Metal roofing is becoming more common on homes across Texas and the U.S. Some homeowners choose it when replacing an older roof, while others start with metal for new construction. This guide explains both the benefits and drawbacks of metal roofing systems to help you understand how they work.
Understanding Metal Roof Advantages
Metal roofing refers to a roofing system made from metal panels or shingles. These systems are usually installed in large panels or interlocking sections. Metal roofs are known for their strength, long lifespan, and energy performance.
Common types of metal used in roofing include:
- Steel (most common, with galvanized or galvalume coatings for rust protection)
- Aluminum (lightweight and naturally corrosion-resistant)
- Copper (develops a natural patina over time)
- Zinc (self-healing and used in high-end designs)
1. Durability And Weather Resistance
Metal roofs stand up exceptionally well to harsh weather conditions. Most steel and aluminum panels can resist wind speeds up to 140 mph, making them suitable for storm-prone regions.
- Impact resistant: Metal roofing withstands hail and falling debris without cracking. Many systems achieve a Class 4 impact rating, the highest available.
- Fire safety: Most metal roofs carry a Class A fire rating, offering protection against wildfire embers.
- Wind protection: The interlocking or continuous panel design helps metal roofs resist being lifted during high winds.
2. Longevity And Low Maintenance
One of the biggest advantages of metal roofs is their extended roof lifespan. While asphalt shingles typically last 15-30 years, metal roofing systems can last 40-70 years depending on the material and local conditions.
Metal roofs also require minimal maintenance compared to other roofing materials. Basic care includes removing debris from metal roof valleys and gutters twice yearly and checking for loose fasteners during annual inspections.
3. Energy Efficiency And Sustainability
Metal roofs reflect solar heat instead of absorbing it. This reflective quality can reduce cooling costs by 10-25% in warm climates like Texas. Many metal roofing products qualify for ENERGY STAR ratings when coated with reflective finishes.
From an environmental perspective, metal roofing contains 25-95% recycled content and is 100% recyclable at the end of its life. This contrasts with asphalt shingles, which contribute approximately 11 million tons of waste to landfills annually.
4. Enhanced Curb Appeal And Real Estate Value
Today’s metal roofing comes in various styles, colors, and finishes. Modern manufacturing allows metal to mimic other materials like:
- Traditional shingles
- Wood shake
- Clay tile
- Slate
This versatility makes metal roofing compatible with nearly any architectural style. Some studies suggest homes with metal roofs may see a 1-6% increase in resale value compared to homes with asphalt shingles.
Recognizing Metal Roof Disadvantages
While metal roofing offers many benefits, it also comes with several drawbacks worth considering before making a decision.
1. Higher Initial Cost
The upfront cost of metal roofing is significantly higher than traditional asphalt shingles. A typical metal roof installation costs about twice as much as an asphalt shingle roof for the same house (see our roof replacement cost guide for more details).
| Roofing Type | Initial Cost (Per Sq. Ft.) | Typical Lifespan |
|---|---|---|
| Asphalt Shingles | $4-$8 | 15-30 years |
| Steel Roofing | $8-$14 | 40-70 years |
| Aluminum Roofing | $9-$15 | 40-70 years |
| Copper Roofing | $15-$25+ | 60-100 years |
Though metal roofs cost more initially, their longer lifespan may provide better long-term value by avoiding multiple replacements.
2. Noise Concerns
Many people worry that metal roofs are noisy during rain or hailstorms. Without proper installation, this can be true. However, when installed with solid roof decking, proper underlayment, and insulation, a metal roof is typically no louder than other roofing types.
The noise level depends on:
- The type of underlayment used
- Whether there’s an attic or ceiling insulation
- The specific metal roof profile installed
3. Denting And Hail Damage Risk
Metal roofs can dent from large hailstones or falling branches, though the risk varies by material. Softer metals like aluminum and copper are more susceptible to denting than steel.
The thickness of the metal (measured by gauge) also affects dent resistance. Lower gauge numbers indicate thicker metal that resists denting better. For example, 24-gauge steel offers better dent resistance than 29-gauge steel.
4. Complex Repairs And Specialized Installation
Installing a metal roof requires specialized skills and experience. Improper installation can lead to problems like leaks or reduced lifespan.
Finding qualified contractors for metal roof installation or repair can be challenging in some areas. When roof repairs are needed, matching the exact color and profile of existing panels may be difficult, especially if the original product has been discontinued.
Differences Between Metal Roofs And Shingles
When comparing metal roofing to asphalt shingles (the most common residential roofing material), several key differences emerge:
- Lifespan: Metal roofs last 40-70 years compared to 15-30 years for asphalt shingles.
- Weight: Most metal roofing is lighter than asphalt shingles, putting less stress on the home’s structure.
- Energy efficiency: Metal reflects heat while asphalt absorbs it, potentially saving on cooling costs.
- Appearance: Metal offers various profiles and finishes, while asphalt provides a more traditional look.
- Installation: Metal typically takes longer to install and requires specialized skills.
Metal roofing performs particularly well in areas with extreme weather conditions like high winds, heavy snow, or intense heat. Asphalt shingles remain popular due to their lower cost and widespread availability of qualified installers.
Latest Trends In Metal Roof Technology
The metal roofing industry continues to innovate with new technologies that address previous limitations and enhance performance.
Cool roof coatings now incorporate infrared-reflective pigments that reflect heat even in darker colors. These coatings help metal roofs maintain energy efficiency regardless of color choice, expanding design options while preserving energy benefits.
Integrated solar systems combine metal roofing with photovoltaic technology. Standing seam metal roofs provide an ideal platform for solar panel attachment without penetrating the roof surface, maintaining weather protection while generating renewable energy.
Improved insulation systems with higher R-values are being incorporated into metal roof assemblies. These systems enhance thermal performance and reduce potential noise concerns, addressing two common hesitations about metal roofing.
Steel roofs for homes now come in more residential-friendly profiles, including metal shingles that closely resemble traditional roofing materials. These options allow homeowners to enjoy metal’s durability while maintaining a conventional appearance that fits neighborhood aesthetics.
Is A Metal Roof Worth It
The value of a metal roof depends on several factors specific to each homeowner’s situation:
- Climate considerations: Metal roofing excels in areas with extreme weather, including high winds, hailstorms, heavy snow, or intense heat.
- Long-term planning: Homeowners planning to stay in their home for decades benefit more from metal’s longevity than those expecting to move within a few years.
- Budget flexibility: The higher upfront cost requires more initial investment, though long-term savings may offset this over time.
- Home design: Some architectural styles naturally complement metal roofing, while others may require careful material selection to maintain aesthetic harmony.
- Local regulations: Neighborhood associations or building codes may restrict roofing material choices in some areas.
For homes in Texas, metal roofing offers particular advantages in handling the intense summer heat and occasional severe storms. The reflective properties help manage cooling costs during long, hot summers, while the wind resistance provides security during storm season.
