Commercial Roof Repair & Replacement

A guide to commercial Roofing in Houston, TX.

Houston’s climate is notoriously tough on roofs intense heat, heavy rain, and the threat of hurricanes all put a commercial roof to the test. A reliable roof is your building’s first line of defense against these extremes. Houston averages nearly 50 inches of rain each year, and tropical storms can bring hurricane-force winds and torrential downpours . Without a sound roof, this severe weather can lead to leaks, interior water damage, mold, and costly business interruptions. Neglecting timely repairs only increases the risks what starts as a minor leak or loose flashing can rapidly escalate into structural damage. In short, maintaining a sturdy commercial roof in Houston’s climate isn’t just about protection; it’s about preserving your property, operations, and investments for the long term.

Who Needs Commercial Roof Repair in Houston

Virtually any commercial property in the Houston area may eventually require roof repair or replacement. The harsh climate doesn’t discriminate – all types of facilities need a solid roof and periodic maintenance. Some of the commercial buildings that commonly require roof repair in Houston include:

• Office Buildings – High-rises and office parks need leak-free roofs to protect employees and equipment.
• Warehouses & Industrial Properties – Large flat roofs on warehouses and factories often face ponding water and UV damage.
• Retail Centers & Malls – Big retail buildings and shopping malls have extensive roofing that must prevent leaks over stores.
• Apartment Complexes & Senior Living Facilities – Multi-family buildings need reliable roofs to protect residents’ homes.
• Storage Facilities – Self-storage unit centers rely on roofs to keep clients’ belongings dry.
• Churches & Community Centers – Large halls and gathering spaces need sound roofs for safety and comfort.
• Schools & Hospitals – Institutional buildings have zero tolerance for leaks that could disrupt learning or patient care.
• Gyms, Restaurants, and Entertainment Venues – Any business serving customers needs a secure roof to avoid closures.
• Municipal Buildings – Government offices, community shelters, and other public buildings also require strong roofing.

In short, if you own or manage a commercial building in Houston, from a small restaurant to a sprawling industrial park, roof repair is eventually part of upkeep. Houston’s climate ensures that even well-built roofs will face wear and tear that needs addressing.

Common Types of Commercial Roofing Systems

Commercial roofs in Houston come in a variety of materials and system types. Each has its own advantages in terms of lifespan, energy efficiency, cost, and maintenance. Flat roof replacement in Houston is especially common, since many commercial buildings have low-slope roofs. Below are the most common commercial roofing systems and how they compare:

Roofing System	Average Lifespan	Energy Efficiency	Typical Cost (Installation)	Maintenance Needs
Asphalt Shingles – commonly used on sloped roofs (e.g. apartments, churches)	20–30 years (premium shingles may last longer)	Moderate (darker shingles absorb heat; cool roof options available)	Low–Moderate ($3–$7 per sq. ft)	Moderate (inspect after storms; replace damaged shingles; clean debris)
Built-Up Roof (BUR) – layers of hot asphalt and felt	20–30 years (can reach 40+ with excellent care)	Low–Moderate (often dark gravel surface, can add reflective coating)	High ($6–$14 per sq. ft)	Moderate (regular inspections; check for cracks in asphalt)
Modified Bitumen – asphalt-based rolls with polymers	~20 years (often longer with good maintenance)	Low (black surface standard; reflective granule options available)	Moderate–High ($5–$12 per sq. ft)	Low–Moderate (durable against foot traffic; inspect seams/flashing)
TPO (Thermoplastic Polyolefin) – single-ply membrane	20–30 years	High (white reflective surface reduces heat)	Low–Moderate ($3–$9 per sq. ft)	Low (welded seams; periodic cleaning and seam checks)
EPDM (Ethylene Propylene Diene Monomer) – single-ply rubber	20–30 years	Low (typically black, absorbs heat; some lighter-color variants exist)	Moderate ($4–$10 per sq. ft)	Moderate (check seams for adhesive wear; protect from punctures)
Metal Roofing – steel or aluminum panels (often standing seam)	40–50+ years	Medium–High (metal reflects some heat; cool roof coatings can improve reflectivity)	High ($6–$15 per sq. ft)	Low (annual check for loose fasteners or rust; long lifespan with minimal upkeep)
Spray Polyurethane Foam (SPF) – sprayed foam with coating	20–30 years (recoat every 10–15 years to extend life)	High (seamless insulation + reflective top coating)	Moderate ($5–$8 per sq. ft)	High (must reapply protective coating periodically; keep drains clear of debris)
Green Roof / “Cool” Roof – vegetative roofs or highly reflective roofs	Varies (green roof membrane 30+ years protected by soil; cool coatings 5–10 years before recoat)	Very High (vegetation or white coatings greatly reduce heat)	Green Roof: Very High ($10–$30+ per sq. ft); Cool Coating: Low ($2–$5 per sq. ft)	Green roofs: High (landscaping care, drainage); Cool roofs: Low (recoat and clean periodically)

As the table shows, each roofing system balances cost and performance differently. For example, a traditional Built-Up Roof has a long track record and can last decades, but it’s heavy and labor-intensive to install. Single-ply membranes like TPO and EPDM are lighter and often cheaper, with TPO offering superior reflective qualities ideal for Houston’s heat. Metal roofing costs more upfront but lasts the longest often well beyond 40 years and is extremely wind- and hail-resistant. SPF foam roofs create a seamless insulated layer great for energy savings, though they need more frequent maintenance to keep the protective coating intact. Green roofs (which incorporate soil and plants) and other cool roof solutions focus on energy efficiency and stormwater management; they can dramatically lower rooftop temperatures and even extend the life of the underlying waterproofing. However, green roofs have high installation costs and require ongoing vegetation maintenance, whereas a simple white reflective coating is a more cost-effective way to achieve a “cool roof.”

In Houston, choosing the right roofing system means considering both the climate demands and your budget/maintenance capacity. For instance, a white TPO or a coated metal roof can help cut cooling costs in our extreme heat. On the other hand, a warehouse might opt for modified bitumen or BUR for toughness against foot traffic and machinery. Understanding these roofing options will help you and your contractor select the best fit for your commercial building.

Signs You May Need Commercial Roof Repair

How do you know when it’s time to call in the pros for a roof repair? Often, your roof will show warning signs long before a catastrophic failure. By staying vigilant for these common indicators, building owners and facility managers can catch issues early and minimize damage. Here are some signs you may need commercial roof repair in Houston:

• Active Leaks or Water Stains: The most obvious sign is water dripping inside or discolored stains on ceilings/walls. If you notice drip spots during rain or brown rings on ceiling tiles, water is infiltrating the roof system. Even a sporadic leak is cause for inspection don’t ignore a “small” leak, as moisture can spread and worsen hidden damage.
• Bubbling or Blistering in Roofing Membrane: Blisters, bubbles, or wrinkles on a flat roof membrane (like on modified bitumen or BUR) signal trapped moisture or air under the surface. When heated by the sun, this trapped moisture forms vapor that pushes up the roofing, creating blisters . Blistering not only indicates a problem but can lead to cracks and leaks if those bubbles burst or grow.
• Ponding Water: After a heavy Houston rain, ponding (standing water) on a flat roof that remains for more than 48 hours is a red flag. Ponding often means the drainage is poor or the roof deck has low spots. Persistent standing water will accelerate roof deterioration and can even add unsafe weight. It’s a clear sign your roof needs better drainage solutions or repairs to restore proper slope.
• Higher Energy Bills: A less obvious clue is a spike in heating/cooling costs. Wet insulation from roof leaks loses its effectiveness, forcing your HVAC to work harder. If your utility bills have been climbing for no apparent reason, it could be due to a roofing issue allowing heat transfer. Waterlogged insulation greatly reduces its R-value (insulating power) and drives up energy usage , so unexplained energy inefficiency might point to a roof leak or moisture problem.
• Mold or Musty Odors: Mold growth in the building (often accompanied by a musty smell) can result from chronic roof leaks. If you detect mildew in upper floors or near ceiling tiles, moisture could be entering from above. Mold not only damages building materials but also poses health risks, so its presence warrants checking the roof and attic for leaks.
• Visible Damage or Debris: It’s wise to do periodic visual checks of your roof (or have a professional inspection). On the roof surface, look for cracked or missing roofing material, torn seams, loose flashing, or rusted metal. On metal roofs, corrosion or rust spots can indicate water standing or coating breakdown. Also watch for gravel from a BUR washing into gutters, which means the roof’s protective top layer is degrading. Any visible wear-and-tear is an early sign repairs may be needed.
• Vegetation or Algae Growth: If plants are growing on your roof or you see algae and moss, it means water is lingering long enough to support growth. Tiny plants or moss can root into roof materials, widening cracks. Vegetation is a symptom of excess moisture either from ponding water or a leak and should be addressed by cleaning and repairing the affected area .
• Recent Storm Damage: After a major storm (common in Houston’s spring and hurricane season), you may notice new problems: for example, damaged flashing, lifted membrane seams, or punctures from wind-blown debris. It’s smart to inspect the roof after any severe weather. Even if leaks aren’t obvious yet, storms can create vulnerabilities that will leak later. Don’t wait for the next rain to find out proactive repairs after a storm can save money long-term.

If you spot any of these warning signs, schedule a professional roof inspection promptly. Addressing issues while they are small (a minor tear, a bit of ponding) is far more cost-effective than waiting until water is pouring through the ceiling. In Houston’s climate, problems can escalate quickly, so early detection is key.

What Causes Roof Damage in Houston

Roofs in the Houston area face a perfect storm of damaging factors. Understanding the common causes of roof damage can help you prevent problems and explain why even well-built roofs might develop issues over time. Here are the major culprits behind commercial roof damage in Houston:

• Sun & UV Exposure: Houston gets intense sun and high UV index for much of the year. Ultraviolet radiation and heat cause roofing materials to break down over time. For instance, asphalt in BUR or modified bitumen can dry out, crack, or become brittle under relentless sun. Seals and caulks on the roof also degrade from UV exposure. The heat itself causes thermal expansion and contraction daily heating and cooling cycles can stress materials and create gaps or splits, especially in older roofs.
• Heavy Rains & Poor Drainage: Houston’s heavy downpours and thunderstorms can overwhelm roof drainage systems. If gutters or interior drains clog (perhaps from debris or leaves), water may pool on the roof. Standing water (ponding) will deteriorate roofing membranes and can seep into any tiny gap or seam. Torrential rain is a big challenge for Houston roofs if water isn’t drained off quickly, even a small flaw can turn into a leak during a storm . Over time, chronic ponding also can lead to structural deck damage from the weight of water.
• Hail Storms: While not as frequent as in North Texas, Houston does experience hail. Hailstones can range from pea-sized to golf ball-sized in severe storms. Hail impacts can puncture membranes, crack shingles or tiles, and dent metal roofing. Even “hail-resistant” roofs can suffer damage in an intense storm. Often hail damage isn’t obvious without close inspection membranes might have tiny punctures or scouring that lead to leaks later. It’s wise to have a post-hail inspection if your building is hit by a hailstorm.
• Hurricanes & High Winds: Houston’s coastal location means occasional hurricanes or tropical storms (and frequent squall lines) that bring extreme wind gusts. High winds can uplift roofing materials tearing off shingles, peeling up membrane sheets, or even prying off metal panels if they aren’t securely fastened. Debris blown by wind (like tree branches or gravel) can become missiles that puncture the roof. The combination of wind-driven rain is especially damaging, as water can be blown sideways into roof seams or under flashings. Hurricane-force winds (74+ mph) can wreak havoc on a roof; even strong thunderstorms with gusts 50–70 mph have caused major roof damage in Houston .
• Temperature Swings and Humidity: Houston is humid nearly year-round. Moisture in the air can work its way into roof materials (especially if they have tiny breaches), contributing to mold or rot in the decking. Also, while Houston doesn’t get extremely cold, winter cold fronts can swing temperatures from the 80s down to freezing occasionally. These fluctuations can cause materials to expand/contract and moisture to condense. Over years, that movement can loosen seams and flashings. Humidity plus warmth can also encourage mold growth on or under the roof if leaks are present.
• Faulty Installation or Repairs: Unfortunately, some roof problems trace back to human error. If a roof was not installed to high standards say, improper flashing around HVAC units, poor adhesion of seams, or inadequate fastening it will be prone to premature failure. Similarly, a subpar repair (using the wrong materials or a quick patch job) might not hold up. In Houston’s climate, any weakness is quickly exposed by the weather. That’s why using an experienced, reputable roofing contractor is critical (more on that below). A well-installed roof will resist Houston’s climate much better than a poorly installed one.
• Lack of Maintenance: Many roof issues are compounded by neglect. If minor wear and tear isn’t addressed, small problems grow. For example, leaves accumulate and clog a drain then the next storm causes ponding that seeps into a tiny hole, turning it into a leak. Or a minor seam separation goes unfixed and expands with each rain. Over several seasons, neglected maintenance can snowball into the need for major repairs or even early roof replacement. Regular maintenance is especially important in Houston to cope with the fast-growing algae, debris from trees (like live oaks dropping leaves year-round), and frequent storms.

By being aware of these causes, building owners can take preventive steps like keeping drains clear, applying reflective coatings to combat UV, and scheduling routine inspections to catch installation flaws or emerging issues. While you can’t control the weather, you can fortify your roof and maintain it so it weathers Houston’s challenges as best as possible.

Houston Weather Considerations for Roofing

Because of Houston’s unique weather profile, commercial roofing here isn’t one-size-fits-all. Climate should inform both your choice of roofing material and your maintenance plan. Here are key Houston weather considerations when it comes to commercial roofs:

• Intense Heat & Sun: Summers in Houston are brutally hot (often 95°F+). Roofing materials that handle high temperatures and UV exposure are a must. Light-colored or reflective roofs (so-called “cool roofs”) are popular because they reflect sunlight, keeping the building cooler and reducing AC costs. For example, TPO and PVC membranes are typically white and offer great UV reflectivity, making them smart choices for Houston’s sun . If you have a darker roof, adding a reflective coating can help. Also, materials like metal or concrete tiles have high heat tolerance. During installation, using UV-resistant sealants and flashings will prolong the roof’s life under intense sun.
• Hurricane-Force Winds: Houston’s roofing must be prepared for the worst-case scenario of a tropical storm or hurricane strike. Even though they are infrequent, when a hurricane comes, it can cause catastrophic roof failures if not properly built. Choose roofing systems and attachment methods with high wind ratings. For flat roofs, this means strong adhesion or mechanical fastening patterns that meet Miami-Dade or similar standards. Wind uplift resistance is critical large single-ply sheets, for instance, need sufficient fastening or they can peel in a storm. Houston building codes may require certain wind standards; a knowledgeable contractor will ensure your roof meets or exceeds those. Additionally, regular inspections before and after hurricane season (which runs June through November) are wise. Consider installing hurricane straps or extra securement on edges and flashings as part of upgrades.
• Heavy Rain & Drainage Design: As noted, Houston gets a lot of rain, and sometimes very quickly. A well-designed commercial roof in Houston should have adequate slope (even “flat” roofs are built with a slight pitch) and redundant drainage. This may include multiple drains or scuppers so that if one clogs, another can handle overflow. When choosing a roof system, consider how it handles standing water for instance, certain membrane roofs can tolerate temporary ponding better than others. Schedule roofing work in seasons with less rain if possible (late winter or early spring often has fewer huge storms than late spring/summer). And always inspect your roof drainage after fall leaves or storms keeping those drains open can’t be overemphasized.
• Humidity and Thermal Shock: Houston’s humidity means mold and mildew can be an issue on roofs (especially in shaded or north-facing sections). Materials that resist mold growth (some membranes have biocides built-in) can be beneficial. Also, the combination of high humidity and occasional cool nights means condensation can form. Make sure your roof assembly has proper vapor barriers and insulation to prevent condensation on the underside of the roof. Thermal shock when a cold rain hits a hot roof or a cold front rapidly cools the roof at night can stress materials. Metal roofs handle thermal cycling well, but built-up roofs might develop small cracks. That’s why periodic inspections are important to catch any weather-related stress fractures early.
• Seasonal Maintenance Timing: In Houston, you can perform roof work virtually year-round (since winters are mild), but timing can still help. Many owners schedule major roof projects in cooler months (October through March) to avoid peak hurricane season and extreme heat. However, emergency repairs can’t wait if it’s July and the roof needs fixing, a professional roofer will still get it done, often by working earlier or later in the day to avoid midday heat. Also consider scheduling a biannual inspection one in the spring (to prep for hurricane season) and one in the fall (to address any summer damage and clear drains before winter). This schedule aligns with Houston’s weather patterns and can extend your roof’s life.
• Hail and Impact Resistance: Not every roofing material handles hail equally. If your building is in an area that has seen hail storms, you might prioritize impact-resistant options. Modified bitumen and BUR gravel roofs actually fare well against small hail due to their thickness and surface texture. Metal roofs can get cosmetic dents but usually remain weathertight (choose a thicker gauge metal for better hail resistance). Some single-ply membranes can be ordered in greater thickness for more durability. Additionally, installing a cover board under the membrane (a common practice in high-end commercial roofs) can help absorb hail impact and protect the underlying insulation.

In summary, Houston’s climate pushes a roof to its limits so design and maintain your roof with those extremes in mind. A roof that might be fine in a mild climate could fail early here. By choosing the right materials (e.g., reflective, wind-resistant) and staying on top of maintenance (especially for drainage), you’ll ensure your commercial roof can handle Houston’s heat and storms for years to come.

Repair vs. Replacement: Making the Right Choice

One of the biggest questions building owners face is whether to repair an existing roof issue or go for a full replacement. It’s not a trivial decision roof replacement is a significant investment, but sometimes continuing to patch an aging roof ends up more expensive (and risky) in the long run. Here’s how to evaluate repair vs. replacement for your commercial roof:

1. Age of the Roof: Start with the roof’s age relative to its expected lifespan. If your roof is only halfway through its life and has a few issues, repairs make sense to get the full value out of the roof. For example, a 10-year-old TPO roof (with a 20-year lifespan) likely has many serviceable years left fixing localized problems is worthwhile. Conversely, if your roof is near the end of its lifespan or already past it, replacement should be strongly considered. An older roof will often develop one issue after another; patching it repeatedly can become a money pit, and older materials might fail in new spots unpredictably.

2. Extent of Damage: The size and spread of the problem areas are critical. A rule of thumb used in the industry (and even some building codes) is if more than about 25% of the roof area is damaged or leaking, a full replacement is more cost-effective. Extensive damage could mean widespread leaks, pervasive moisture under the membrane, or many failing seams. In those cases, doing numerous spot repairs might cost nearly as much as a new roof without the lasting benefit. Also, if damage is substantial, building codes may require bringing the whole roof up to current code when you do repairs. Rather than patching all over, it can be smarter to invest in a new, warrantied roof that resets the clock on your roof’s lifespan.

3. Condition of Underlying Deck and Insulation: Sometimes what’s under the roof membrane influences the decision. If a leak has caused deck rot or saturated insulation over a broad area, those sections will need replacement anyway. If testing (like infrared scans or core samples) shows a lot of wet insulation, a roof replacement is often advisable to properly remove and replace those materials. A repair could fix the membrane, but trapped moisture can continue to cause problems (mold, deteriorating decking). A new roof job would address the full assembly (deck, insulation, membrane), ensuring the entire system is sound.

4. Frequency of Repairs: Look at the track record. Have you had to call for roof repairs frequently in the last couple of years? If leaks or issues keep popping up, that’s a sign the roof is failing overall. When repairs become more frequent and costly, it’s usually time to stop patching and plan a replacement. Not only does this save money long-term, it also buys peace of mind you don’t have to worry about the next rainstorm causing another leak once a new roof is in place.

5. Cost Considerations: Upfront cost is a big factor. Generally, repairs will cost less than a full replacement at any given time. If budget is tight, you might opt for targeted repairs to buy some time. However, consider the long-term cost: multiple repairs add up, and they don’t come with the long warranty that a new roof would. It might be helpful to get quotes for both repairing and replacing. For instance, if a repair is quoted at, say, $20,000 and a full replacement is $60,000, you then weigh how many years the repair might extend the roof versus a new 20-year roof. Sometimes building owners choose a middle road: do essential repairs now, but start budgeting for a replacement in the near future (perhaps in the next fiscal year). Also keep in mind that new roofing can improve energy efficiency, which has an economic benefit over time (lower utility bills) effectively offsetting some of the replacement cost.

6. Future Plans for the Building: Consider the bigger picture. Are you planning to hold onto this property for many years, or possibly sell it soon? If selling or refinancing, a new roof can increase property value and make the building more attractive (no one wants to buy a building with a known bad roof). If you plan to keep it, a replacement might align with a capital improvement plan to reduce maintenance headaches. Sometimes, owners phase their re-roofing or instance, replace one section this year, another section next year especially on very large facilities, to spread out costs.

In the end, get a trusted professional opinion. A reputable Houston commercial roofer (like Amstill Roofing) can inspect the roof and give you an honest assessment of whether repairs will suffice or if a replacement is recommended. They should provide reasoning e.g., “the membrane is failing across the field, not just in one area, which is why replacement is wise.” Understanding the why behind the recommendation is important. You want to make an informed decision balancing cost, risk, and the expected remaining life of the roof. Remember, a good contractor will act as a partner in this decision, not just push the most expensive option. At the end of the day, safety and protecting your business are the top priorities – if a patch will safely get you 5 more years, great; if not, investing in a new roof could save you from disaster in the next big storm.

Maintenance Best Practices for Commercial Roofs

The key to maximizing your commercial roof’s lifespan (and avoiding surprise leaks) is regular maintenance. Think of your roof as a critical asset that needs periodic care much like changing the oil in a vehicle. Especially in a climate as challenging as Houston’s, proactive maintenance can add years to a roof’s life. Here are some best practices for maintaining a commercial roof:

• Schedule Regular Inspections: Frequent roof inspections are your first line of defense. It’s recommended to have a professional inspect a commercial roof at least twice a year typically once in the spring and once in the fall . Spring inspections catch any winter damage and prepare for the upcoming heavy rains and hurricane season. Fall inspections check for any issues from the hot summer and ensure the roof is ready for cooler, wetter winter months. Additionally, always schedule an extra inspection after any major storm or hurricane that might have caused damage. Regular inspections will catch small problems (like a hairline membrane crack or a loose piece of flashing) before they turn into leaks.
• Keep Drainage Systems Clear: One of the simplest but most impactful maintenance tasks is keeping gutters, downspouts, and internal drains clear of debris. Given Houston’s tree foliage and occasional high winds, roofs can accumulate leaves, twigs, and trash that clog drainage. Make it a routine (part of the inspection or separate quarterly task) to clear out all drains. Ensure that strainers over internal drains (if your flat roof has them) are free of leaves. Proper drainage prevents ponding water which, as discussed, can severely damage the roof. It’s cheap and easy to do, but the consequences of neglect can be expensive.
• Address Minor Repairs Promptly: If an inspection or your own observation reveals any issue, fix it promptly. Do not procrastinate on repairing small things like a torn seam, a small puncture, a loose piece of metal flashing, or a couple of missing shingles on a sloped roof section. Houston’s climate will exploit any vulnerability; a little tear can become a wide open seam after a few rounds of heating, cooling, and wind. Prompt repairs (often inexpensive) prevent them from ballooning into major leaks (which are costly). For example, re-sealing a gap around an HVAC curb now can save you from interior water damage later.
• Maintain Rooftop Equipment: Many commercial roofs have HVAC units, vents, skylights, solar panels, or other equipment installed on them. These are points where the roof has penetrations and flashings common leak sources if not maintained. Work with your HVAC contractor to ensure condensation lines aren’t leaking on the roof and that units are properly flashed. If an HVAC tech accesses the roof, have them inform you of any damage they might accidentally cause (tools dropped can puncture membranes). Likewise, check that pipe penetrations have intact seals. Essentially, any accessory on the roof needs to be well-integrated with the roofing system maintenance on those will prevent them from becoming weak points.
• Ensure Proper Ventilation: This is more applicable to pitched commercial roofs or attic spaces under the roof. Proper attic ventilation (via ridge vents, soffit vents, etc.) helps reduce heat and humidity build-up under the roof, which in turn extends roof material life and prevents moisture issues. For flat roofs with no attic, ventilation of the building still matters for controlling indoor humidity. While this is a step removed from the roof surface, it’s part of holistic roof health a dry, cooler underside of the roof is less prone to issues.
• Apply Reflective Coatings or Sealants as Needed: Over time, the roof’s original surface may wear down. Many commercial roofs benefit from periodic re-coating or sealing. For example, a modified bitumen roof might be coated with an aluminum or elastomeric coating every 5-7 years to rejuvenate its UV protection. SPF foam roofs must be recoated every decade or so to protect the foam. Even metal roofs can be sealed at seams or have a new paint coating applied to prevent corrosion. These maintenance coatings can extend roof life significantly by adding a fresh protective layer. They’re much cheaper than a replacement and can often add several years of service. Always use a coating compatible with your roofing material and installed by professionals according to manufacturer specs (to maintain any warranty).
• Document and Plan: Keep a log of all inspections, maintenance, and repairs. This history is invaluable. It helps you track recurring issues (e.g., that one area that ponds water) and informs future decisions (like when to schedule a replacement). Many roofing companies offer maintenance plans or even roof asset management programs that provide detailed reports. Even if you maintain it in-house, record what was found and fixed each time. Having a documented maintenance history can also be beneficial for warranty claims or when selling the building, as it shows the roof was well cared for.
• Train Staff for Roof Awareness: If you have facility management staff, ensure they know the basics of roof care. For instance, if they need to go onto the roof, instruct them to avoid stepping on fragile areas and to report any issues they see. Minor things like closing roof hatches gently (to not damage flashing) or not dragging heavy equipment across the roof can prevent incidental harm. Essentially, treat the roof as a sensitive asset because it is.

By following these best practices, you’ll extend the life of your commercial roof and minimize unplanned downtime. In fact, major roofing manufacturers often state that with proper maintenance, a roof can last well beyond its warranty period. A little proactive care goes a long way. As one major roofing company notes, regular maintenance can “significantly extend the life of your roof” meaning more years before you need to invest in a new one. Plus, a well-maintained roof is far less likely to surprise you with leaks during the next Gulf Coast downpour. It’s peace of mind worth pursuing.

The Commercial Roof Repair Process

If you’ve never been through a commercial roof repair or replacement before, you might wonder what the process looks like. While every project has its unique aspects, most professional roofing contractors in Houston (including Amstill Roofing) will follow a general series of steps to ensure the job is done safely and effectively. Here’s what to expect in a typical roof repair process:

1. Initial Inspection & Assessment: The process starts with a thorough roof inspection. A roofing expert will come on-site to assess the condition of your roof, identify problem areas, and determine the cause of any issues (for example, locating the source of a leak). They may take photos, measure the roof, and possibly do moisture scans if leaks are widespread. After this assessment, you should receive a detailed report or explanation of what was found, along with repair recommendations. In the case of a significant issue, they might also discuss whether repair or replacement is more appropriate (as covered above).
2. Repair Proposal & Estimate: Based on the inspection, the contractor will prepare a scope of work for the repair and provide an estimate of the cost and timeline. The proposal will outline what they plan to do e.g., “replace 10 feet of metal flashing along west parapet, patch 3 membrane blisters, reseal around 4 pipe penetrations.” Reputable roofers will be transparent about costs for labor, materials, and any contingencies (like wet insulation replacement if found). You’ll have a chance to review this and ask questions. Once you agree and sign off, the project will be scheduled.
3. Scheduling and Preparation: The roofing company will coordinate with you to schedule the repair work at a convenient time. They’ll consider weather forecasts (avoiding rainy days for open-roof work whenever possible) and your business operations. Many Houston commercial roof repairs can be done with minimal disruption to the building occupants often work is done early or on weekends if needed to avoid, say, a busy retail time. Before work begins, the contractor will acquire any necessary permits (for larger repairs or structural work, permits may be needed, though minor repairs typically do not). They’ll also stage any needed equipment for instance, setting up ladders or cranes to hoist materials, and placing tarps or protective plywood to safeguard your property (landscaping, AC units, etc.) during the repair.
4. Safety Measures: On the day of work, the crew will first implement safety measures. This includes wearing appropriate fall protection harnesses, setting out warning signage or caution tape on the ground (to keep people away from the work zone), and adhering to OSHA safety guidelines. Roof work can involve hazards like open flame (if using torches on mod-bit repairs) or heavy materials, so a professional crew will make safety a priority for both workers and anyone in/around the building. If the building is occupied, they may coordinate to temporarily restrict access to certain entrances or areas directly below the roof work for safety.
5. Execution of Repairs: Now the actual repair work takes place. The specifics vary by roof type, but generally:
   • Damaged material will be removed or cut away. For example, if a section of membrane is punctured, they’ll cut out a neat section around it.
   • The area is cleaned and prepped. This could mean removing wet insulation, cleaning debris, or drying the area.
   • New materials are installed to fix the issue. This might involve patching a membrane (welding a new piece of TPO over a hole), installing new flashing or metal strips, applying roofing cement or sealant to cracks, or even replacing a few shingles or panels on sloped sections.
   • For larger repair jobs, they might work section by section to keep the roof waterproof. If any portion of the roof is opened up (exposing the substrate), they’ll close it up before the day’s end or before any rain. In Houston, experienced crews keep an eye on pop-up thunderstorms they will cover any open areas with tarp if a surprise rain shower comes.
   • The materials used will match or be compatible with your existing roof. Often, they will use manufacturer-approved repair kits so that your roof’s warranty remains valid (if still under warranty).
   • Throughout the process, the crew should maintain a clean work environment tossing scraps into a trash bin, not leaving loose screws around, etc., both for safety and cleanliness.
6. Quality Checks & Final Inspection: After the repair work is completed, the crew will do a final walkthrough/inspection of their own. They’ll double-check that all seams are sealed, all flashings are secure, and that the repair meets the project specs. They may do water testing for leaks if appropriate (for instance, spraying water to ensure a leak is indeed fixed). They will also ensure no tools or debris are left on the roof. If it’s a replacement or large repair, a supervisor or project manager might do a formal final inspection, possibly with you (the client) present to go over what was done. In Houston, if a permit was pulled, an inspector from the city may need to sign off on the work as well for code compliance (this is more common in full replacements).
7. Clean-Up: A good contractor will leave your property as clean or cleaner than they found it. All old materials, debris, and trash will be removed and hauled away. If any fell around the building, they’ll pick it up. Many roofers use magnets to collect stray nails if they were working with fasteners. This step is important for safety (no one wants to find a roofing nail in their tire) and is a mark of professionalism.
8. Documentation & Warranty: You should receive documentation of the repair. This may include an invoice describing the work performed, photos of before and after (some companies provide this), and details of any warranty on the repair. Many roofing contractors will warranty their repair work for a certain period (e.g., 1 year warranty on patches, etc.), and materials may carry their own warranty. If your roof was under a manufacturer warranty, documentation of proper repair by a certified contractor is important to keep that warranty intact. Keep all these records.
9. Ongoing Support: After the repair, a top-notch roofer will often provide guidance on maintenance to prevent future issues. They might suggest you to inspect a bit more often, or they may offer a maintenance program. Also, you’ll have their contact info so you can reach out if any issue arises with the repaired area. Reputable Houston roofing companies (like Amstill) stand by their work if that patch somehow doesn’t hold during the next storm, you can expect them to make it right.

For a full roof replacement, the process will include more steps (like tearing off the old roof, extensive installation work, and possibly a longer project timeline), but the general customer experience is similar inspection, proposal, scheduling, safety, execution, final inspection. In either case, communication is key. You should feel informed at each stage: knowing when crews will be on your building, who to contact with questions, and what to expect next. This is why choosing a reliable contractor is so important they make the process smooth and keep you in the loop.

By understanding the repair process, you can approach it with confidence rather than concern. When you work with a trusted partner like Amstill Roofing, the process will be professional and efficient, with an emphasis on quality and minimal disruption to your operations. You’ll be left with a solid repair and peace of mind that the problem was resolved correctly.

Cost Breakdown: What to Expect

Cost is often the first question building owners have about roof work: “How much will this cost me?” The answer, of course, depends on many factors roof size, type, extent of damage, materials chosen, etc. Below, we offer a general cost breakdown for commercial roof repair and replacement in Houston. These are ballpark figures to guide your budgeting; for an exact quote, an on-site inspection is needed. Prices can fluctuate with material costs and market conditions.

1. Repair Costs: Minor repairs can be surprisingly affordable, while major repairs approach replacement costs. Here’s a rough guide:

• Small patch or leak repair: Typically $500 to $1,500. This might cover fixing a couple of membrane punctures, sealing a small flashing gap, or replacing a few damaged shingles on a small area.
• Moderate repairs: $2,000 to $5,000. This could include multiple leaks to address, replacing sections of metal flashing, repairing a larger area of membrane, or fixing issues around several penetrations. The crew might be on site a full day or two for this level of work.
• Extensive repairs: $5,000 to $15,000 (or more). This might involve issues over a widespread area but stopping short of full replacement. For example, applying a roof coating over the entire roof for restoration, or replacing one whole section of a multi-section roof. At this stage, one must evaluate if full replacement of that area is more cost-effective. However, coatings and restorations can extend life and come in lower than a tear-off replacement.

Keep in mind, if your roof is under warranty, some repairs might be covered or need to be done by a certified contractor to maintain coverage. Also, emergency repairs (like tarping a hole after a storm) might have additional after-hours fees, but those are usually temporary fixes billed on time and materials.

2. Replacement Costs: Roof replacement is usually priced by the square foot for materials and labor. Here are typical ranges for different roof types in Houston (materials + installation):

• TPO or PVC single-ply: Approximately $4 to $9 per sq. ft in Houston . That means a 10,000 sq. ft flat roof replaced with TPO could cost on the order of $40,000 $90,000. TPO is on the lower end of cost among single-ply options, whereas PVC can be a bit more due to material cost.
• EPDM rubber: Roughly $4 to $10 per sq. ft , similar to TPO/PVC. EPDM can sometimes be a bit cheaper material-wise, but often the costs end up comparable. So, a 10,000 sq. ft EPDM roof might be $40,000–$100,000.
• Built-Up Roof (BUR) or Modified Bitumen: Typically $5 to $12 per sq. ft . These multi-ply systems involve more labor (and heavy materials like asphalt), so while materials aren’t very expensive, the labor pushes the price up. A built-up roof for 10,000 sq. ft might be in the $50,000–$120,000 ballpark. The range is wide because the number of plies (layers) can vary, and adding insulation or a reflective cap sheet also affects cost.
• Metal Roofing: $6 to $15 per sq. ft on average . Simpler corrugated metal panels might be on the lower end ($6-$8), while high-end standing seam architectural metal can be on the higher end ($12-$15). A 10,000 sq. ft metal roof could thus range from $60,000 up to $150,000. Metal has a higher upfront cost but remember it also lasts the longest.
• Spray Polyurethane Foam: Around $5 to $8 per sq. ft for the initial installation . So a 10,000 sq. ft foam roof might be $50,000–$80,000. However, note that you’ll also have periodic recoating costs down the line. Some building owners like SPF because it can be installed over an existing roof (no tear-off), saving disposal costs.
• Green Roof (vegetative): This is highly variable, but extensive green roofs (thin soil, hardy plants) often run $10 to $30 per sq. ft, while intensive green roofs (thicker soil, gardens, trees) can be $30 to $100+ per sq. ft . Green roofs also may involve structural upgrades to handle the weight, which is an extra cost. Because of the cost and complexity, green roofs are less common in Houston except on certain eco-friendly or high-profile buildings.
• Roof Coatings: If your roof is a candidate for restoration with a coating (rather than replacement), that might cost $2 to $5 per sq. ft . This is significantly cheaper than a full replacement and can extend the roof’s life by 5-10 years. Not all roofs qualify (the existing roof must be fundamentally sound), but it’s worth asking your contractor if a coating is an option.

To put it in perspective, let’s consider a typical Houston scenario: say you have a 20,000 sq. ft warehouse with an aging BUR roof. To completely tear-off and replace with a new modified bitumen roof, you might expect a quote around $150,000 (20k sq. ft at ~$7.50/sf). If you choose TPO instead, maybe it’s a bit less, around $120,000 (at ~$6/sf). If the roof is still mostly okay and you opt for a restoration coating, perhaps it’s $50,000 (at $2.50/sf) to buy another 5-10 years of life. These numbers are illustrative, but they highlight how the choice of material and method impacts the cost.

3. Other Cost Factors: In addition to the basic ranges, be aware of other factors that can affect price:

• Tear-Off vs. Overlay: If the old roof needs to be removed (torn off) before installing the new one, that adds labor and disposal cost. Some roofs can be overlayed (a new membrane over the old) if code allows and if there’s only one existing layer. Houston codes typically allow up to 2 roofing layers in many cases. Doing an overlay saves money but is only advisable if the existing roof is dry and stable.
• Insulation: Commercial roof replacements often include new insulation for energy code compliance. The thicker the insulation (measured in R-value), the higher the material cost. This is usually worth it in the long run for energy savings, but it’s a line item to consider.
• Flashings, Deck Repairs: A replacement quote might include an allowance for replacing sections of rotten deck or extensive new sheet-metal flashings. If once they start work, they find more deck damage than expected, there could be extra charges (usually outlined in the contract as per-foot cost for wood replacement).
• Height and Accessibility: A roof that’s 3 stories up in a tight urban lot might cost more to service than one that’s easily accessible with a ladder. Cranes or special equipment could be needed to hoist materials. Similarly, if your roof has a lot of HVAC units (which require careful work around), that could add labor time.
• Warranty Level: Opting for a longer or no-dollar-limit (NDL) warranty from a manufacturer may require using their certified installers and premium materials, which can increase cost slightly. However, many owners opt for it because it provides peace of mind (typically 20-year guarantee or similar).
• Timing and Demand: Roofing is somewhat seasonal. After a big storm or hurricane in Houston, demand for roofers spikes and so do prices due to workload (and sometimes material shortages). Planning a project in a slower period might yield more competitive pricing. Also, rising oil prices can affect roofing (asphalt is an oil product, as are many synthetics), so costs can fluctuate year to year.

4. Financing and Tax Considerations: Paying for a big roof job can be daunting. Some roofing companies offer financing or payment plans for large projects. Also, be aware that tax laws can help under IRS Section 179, many businesses can deduct the full cost of a new commercial roof in the year it’s installed (rather than depreciating over decades) . That is a huge incentive, effectively lowering the net cost of a roof replacement for many companies. Additionally, energy-efficient roofing might qualify for tax credits or utility rebates. Always discuss with your accountant or financial advisor, but realize that the sticker price of a roof could be partly offset by tax benefits (and remember the value of protecting your assets).

In summary, while the cost of commercial roof repair or replacement in Houston can vary widely, having a rough idea of ranges helps budget and avoid sticker shock. A small repair might be a thousand bucks; a full flat roof replacement might be in the six figures. The best approach is to get an inspection and quote for your specific situation. A trustworthy contractor will explain the costs in detail and even suggest options at different price points (for instance, good, better, best materials). By being informed and planning ahead (perhaps setting aside reserves in your capital budget for inevitable roof work), you can manage this significant building expense in a responsible, predictable way.

Choosing the Right Roofing Contractor

Selecting a roofing contractor is arguably as important as choosing the roofing material. A well-installed mediocre material will outperform a poorly-installed premium material any day. In Houston, you have many roofing companies to choose from here’s how to identify a reliable, high-quality commercial roofing contractor that will be a true partner in protecting your building:

• Experience and Track Record: Look for a contractor with a long history in the Houston area and specific experience with commercial roofs. Commercial roofing (especially flat roofs, metal, etc.) is a specialized skill set you want a company that isn’t just a residential shingle roofer dabbling in flat roofs, but has a proven track record with the systems you need. An experienced contractor will have seen Houston’s worst weather and know how to build roofs to withstand it. Don’t hesitate to ask for references or examples of similar projects they’ve completed (e.g., “Have you done a roof on a shopping center or warehouse like mine?”).
• Proper Licensing and Insurance: This is non-negotiable. Ensure any roofer you consider is fully licensed to operate in Texas and carries adequate insurance (both general liability and worker’s comp). Unfortunately, after big storms, “fly-by-night” unlicensed roofers show up offering quick fixes avoid those. A reputable company will readily provide proof of insurance and licensing. This protects you in case of accidents on the job or any issues with the workmanship.
• Knowledge of Local Codes and Requirements: Houston and its surrounding municipalities have building codes that dictate roofing practices (especially for windstorm compliance closer to the coast). Your contractor should be well-versed in these. For example, certain counties require inspection stickers for windstorm compliance on roof replacements. The contractor should handle permits and ensure the roof meets or exceeds code. Familiarity with Houston’s building code and any special requirements (like energy code for commercial roofs, hurricane straps in coastal zones, etc.) is a sign of a true professional.
• Manufacturer Certifications: The best contractors often have certifications from roofing material manufacturers (e.g., GAF Master Elite for shingles, or Carlisle/Versico authorized installer for single-ply membranes). These certifications mean the crew has been trained on those products and can offer the enhanced manufacturer warranties. For instance, Amstill Roofing is a certified Versico installer an indication of expertise with TPO/PVC systems. Choosing a certified contractor can give you peace of mind that they will install the roof per the highest standards set by the manufacturer.
• Local Presence and Stability: A roofing company with a local Houston office (or offices) and that has been in business for many years is preferable. Local presence means quicker response if you have a need, and it means they understand Houston’s climate intimately. Stability is important because of warranties you want the roofer to be around years from now if you need to call on a workmanship warranty. Amstill Roofing, for example, has been serving Houston since 1974 that longevity speaks volumes. Be cautious of out-of-town companies that flood the area after a hurricane; they might do the job and vanish, leaving you high and dry if something goes wrong later.
• Reputation and Reviews: Check the company’s reputation. Read customer reviews and testimonials, not just on their website (which will always be positive), but on third-party sites like Google, Yelp, or Better Business Bureau. Look for patterns: are customers consistently satisfied? How does the company respond to any negative feedback? A high volume of positive reviews (especially on commercial projects) is a great sign. For instance, Amstill Roofing has over 1,000 Google reviews which indicates a large number of satisfied clients in the community . You can also ask colleagues or other property managers for recommendations word of mouth in the business community is valuable.
• Detailed Written Estimates: A professional contractor will provide a clear, written proposal or estimate for your roofing work. It should outline the scope, materials, timeline, and payment schedule. Be wary of any roofer who only gives a verbal quote or tries to pressure you into signing quickly. You have the right to take time to review and compare bids. The level of detail in an estimate often reflects the contractor’s thoroughness. It should also specify warranty terms (e.g., 2-year workmanship warranty, 20-year manufacturer warranty on materials, etc.).
• Communication and Professionalism: Pay attention to how the contractor handles communication from the first call. Are they responsive to inquiries? Do they show up on time for appointments? Are they willing to answer questions and explain things in layman’s terms? A roofing project can be complex you want a contractor who communicates clearly and treats you with respect. Professionalism during the bidding phase likely translates to professionalism on the job site (e.g., crews in uniform, job site kept tidy, etc.). Trust your gut if something feels off or if they are overly pushy, it might be best to walk away.
• Fair Pricing (Not Just the Lowest Bid): While cost is important, the lowest bid is not always the best. Be skeptical of any quote that is dramatically lower than others the contractor might be cutting corners, using subpar materials, or not fully understanding the project scope. A decent contractor might not be the cheapest, but they provide value in quality of work and reliability. It’s better to spend a bit more for a roof done right than to save a little now but pay more later in repairs. That said, a good contractor will be competitive and transparent about their pricing. If one bid is higher, ask why they might be including something important that others left out.
• Safety and Crew Training: Roofing can be dangerous work. A responsible contractor has a strong safety program and trains their crew in safety protocols. This protects workers and you (from liability and accidents on your property). You can inquire about their safety record or what safety measures they plan for your job. Companies that invest in training (both for installation skills and safety) demonstrate professionalism.
• Contract and Payment Terms: When you choose a contractor, make sure everything is put in writing in a contract. Do not rely on handshake deals for something as major as a roof. The contract should detail the scope, timeline, warranties, cleanup, and payment terms. In Texas, it’s common not to pay full cost upfront a reasonable deposit, then progress payments or payment upon completion is standard. Never pay 100% in advance. Also, ensure the contract addresses how change orders are handled (if unexpected work arises). A solid contract protects both parties and ensures everyone is on the same page.

In summary, do your homework before hiring a commercial roofer. The right contractor will not only do a good job on your roof, but they’ll also make the process stress-free and stand behind their work. This is a significant investment you want the team with experience, integrity, and skill. Many Houston businesses ultimately choose Amstill Roofing for these very reasons: a long track record, local roots, strong reputation, and commitment to quality. Whomever you choose, take the time to vet them it’s worth it.

Frequently Asked Questions (FAQ)

Q: How long does a commercial roof repair or replacement take?

A: The timeline depends on the scope of work. A small repair (like patching a leak) might be completed in just a few hours or a single day. A more involved repair (replacing flashing, repairing multiple sections) could take a couple of days up to a week. For a full roof replacement, time frames can range from several days for a mid-sized building to a few weeks for a very large facility. For example, replacing a 20,000 sq. ft flat roof might take 1-2 weeks, depending on weather interruptions and crew size. Weather is a big factor in Houston if rain delays occur, the project extends accordingly (roofers will pause during rain for safety and to protect your interior). A good contractor will provide a schedule and keep you updated on progress. They’ll also work with you to minimize disruption, potentially working in sections so your entire roof isn’t exposed at once, and even doing critical areas during off-hours if needed.

Q: Will my business operations be interrupted during roofing work?

A: Professional roofing contractors strive to minimize disruptions. For minor repairs, you’ll likely notice very little impact aside from perhaps some noise from footsteps or tools on the roof. For major work or replacements, there will be some noise (hammering, drilling, the hum of equipment) and possibly vibration, which can be mildly disruptive depending on your type of business. However, businesses almost always remain operational during roofing projects. Contractors can coordinate to work during evenings or weekends for particularly loud tasks if it’s a concern. They may section off parking areas below where they are working for safety, but they’ll inform you of that in advance. If you run something like a sensitive lab or a recording studio where noise/vibration is a big issue, discuss that with the roofer they can plan accordingly. Overall, expect some level of inconvenience (noise, workers on site), but you should be able to continue business as usual in most cases. Clear communication with your contractor and perhaps notifying your employees or tenants about the project timeline can help everyone prepare for the temporary change.

Q: Are there any tax incentives or financial benefits for roof replacement?

A: Yes, there can be significant financial/tax advantages. Under the current U.S. tax law, many commercial roof replacements qualify for Section 179 expensing, which means you can deduct the full cost of the roof in the same year rather than depreciating it over 39 years . This has been a game-changer for businesses effectively, it can reduce your tax bill substantially in the year you do the roof, helping offset the cost. Additionally, if the new roof improves energy efficiency (for instance, adding more insulation or using a cool roof membrane), it might qualify for energy-efficiency tax credits or deductions (such as the 179D deduction for energy-efficient commercial buildings). In Houston, some utility companies occasionally offer rebates for cool roofing or added insulation as well. On the insurance side, if you’re replacing a roof due to storm damage, your insurance might cover a portion of the cost (typically you pay the deductible, they pay the rest, if it’s an approved claim). Also, having a new roof can sometimes reduce your property insurance premiums, especially if the new roof is fire-resistant or hail-resistant compared to the old one. It’s wise to consult a tax professional about the exact benefits for your situation, but many building owners have been pleasantly surprised at how much of the investment they can recoup at tax time.

Q: How long will my new commercial roof last?

A: The lifespan of a roof depends on the material and how well it’s maintained. Here are rough guidelines for Houston: TPO/PVC single-ply roofs can last 20-30 years, EPDM rubber roofs about 20-25 years (sometimes up to 30), and metal roofs can last 40-50 years or more . Built-up or modified bitumen roofs often last around 20 years, though some well-maintained BURs have gone 30+. A spray foam roof might last 20 years before recoat, but if you keep recoating it, the underlying foam could last much longer. A properly done green roof could last 30-40 years for the membrane (the garden above protects it from UV). Keep in mind these numbers assume regular maintenance. A roof that never sees an inspection or repair in 10 years might not reach its expected lifespan due to unchecked issues. Houston’s sun can age things faster, so coatings and care matter. Many manufacturers offer warranties of 15, 20, or 30 years, which gives a clue to expected life if maintained. Also note, a roof doesn’t necessarily fail right after its warranty ends if you maintain it, you might squeeze extra years out of it. When a roof nears the end of its life, you’ll see signs (leaks, wear) that indicate it’s time to think about replacement.

Q: Can roof work be done in the winter or during cooler months?

A: Absolutely. Houston’s winters are generally mild, with only occasional very cold days. Roofing can be performed year-round here. In fact, winter (or late fall) can be an ideal time for roof projects because there are fewer thunderstorms and the temperatures are easier on workers (and some materials). Certain materials have temperature limits for installation for example, some adhesives or sealants shouldn’t be applied below a certain temperature (often around 40°F). But Houston rarely stays below 40°F for long, and work can be scheduled midday when it’s warmer if needed. The key is ensuring any rain is out of the forecast and adapting to shorter daylight hours in winter. A cold front that brings freezing temps for a night might pause a project, but typically there will be a stretch of clear, cool days after that which are fine for roofing. So, unless it’s an unusually wet or cold winter, roofing goes on. Many businesses actually prefer winter for roof replacement to avoid the peak rainy season and the hottest days. Each season has pros and cons: summer has long days but intense heat (and pop-up storms), spring has rain and hail threats, fall is generally good but can have hurricanes early on, and winter is cool and relatively dry but days are shorter. In Houston, you can schedule roofing whenever it fits your calendar a competent roofer will work around the weather within that window.

Q: What kind of maintenance does a new roof require, and will I get a maintenance plan?

A: A new roof, while low-maintenance, isn’t “no” maintenance. You’ll want to start a regular inspection routine (at least annually, ideally twice a year as noted earlier) even from year one. This is partly to satisfy warranty conditions many manufacturer warranties require proof of regular maintenance. Maintenance for a new roof typically includes checking that drains remain clear, making sure no seals or caulking have failed (perhaps at year 5 or so you might need to re-caulk some flashing), and keeping the roof clean of debris. If you have a rooftop with a lot of tree debris, periodic cleaning is important to avoid those dead leaves causing moisture retention. Some roofing companies offer a maintenance program where they come out annually or biannually to handle these inspections and minor tune-ups for you this can be worth it to prolong your roof’s life and catch issues while under warranty. Ask your contractor if they offer such a program; Amstill Roofing, for example, can set up a maintenance schedule for you. Also, maintain a file for your roof keep the warranty paperwork, inspection reports, and any repair documentation. A new roof is a significant investment, so think of maintenance as protecting that investment. The good news is, a new roof shouldn’t need any major work for many years if installed properly mostly just watchfulness and small preventive measures.
