In Texas, hailstorms are common and can happen with little warning. They often occur from March through May, though severe events can happen any time of year.
When hail hits a roof, the damage depends on the size of the hail and the type of roofing material. Some materials crack or dent, while others are built to handle impact better.
This article explains how well different roofing materials handle hailstorms. It also introduces important terms and ratings used to measure hail resistance.
The Importance Of Hail Resistant Roofing
Hail resistant roofing protects homes in areas where hailstorms happen frequently. Texas consistently ranks among the top states for hail damage claims according to the Insurance Information Institute, with thousands of incidents reported annually.
When hail damages a roof, it can lead to leaks and interior water damage. This often results in costly repairs beyond just the roof itself. Selecting materials that resist hail impact helps maintain your roof’s integrity longer.
Most hail damage occurs during spring and early summer in Texas, though storms can happen year-round. The severity varies by region, with some areas experiencing more frequent or larger hailstones than others.
Understanding UL 2218 And Class 4 Ratings
The UL 2218 impact resistance test is the industry standard for measuring how well roofing materials withstand hail. This test involves dropping steel balls of various sizes onto roofing samples to simulate hail impact.
Based on the results, materials receive ratings from Class 1 (lowest resistance) to Class 4 (highest resistance). These ratings help homeowners compare how different products might perform during actual hailstorms.
- Class 1: Minimal impact resistance
- Class 2: Moderate impact resistance
- Class 3: High impact resistance
- Class 4: Highest impact resistance (best for hail-prone areas)
Class 4 materials offer the best protection against hail damage. Many insurance companies recognize this by offering premium discounts for homes with Class 4 rated roofing in hail-prone regions like Texas.
Comparing Common Roofing Materials In Hailstorms
Different roofing materials respond to hail impact in unique ways. Some dent but remain watertight, while others might crack or break under the same conditions.
| Material Type | Impact Rating | Typical Lifespan | Cost Range ($/sq ft) | Hail Resistance Level |
|---|---|---|---|---|
| Standard Asphalt | Class 1-2 | 15-20 years | $3.50-$5.50 | Low |
| Impact-Resistant Asphalt | Class 3-4 | 25-30 years | $4.50-$7.00 | High |
| Steel (Metal) | Class 3-4 | 40-70 years | $7.00-$12.00 | Very High (may dent) |
| Aluminum (Metal) | Class 2-3 | 40-60 years | $6.00-$10.00 | Moderate-High |
| Clay/Concrete Tile | Class 2-3 | 40-50 years | $8.00-$15.00 | Moderate (can crack) |
| Slate | Class 3 | 50-100 years | $15.00-$30.00 | High (can crack) |
| Synthetic (Rubber/Polymer) | Class 4 | 30-50 years | $7.00-$12.00 | Very High |
1. Asphalt Shingles And Best Hail Resistant Shingles
Standard asphalt shingles often suffer granule loss and cracking during hailstorms. The impact can expose the fiberglass mat underneath, leading to further deterioration and potential leaks.
Impact-resistant or “hail proof shingles” are specially designed with stronger materials. These best hail resistant shingles use reinforced fiberglass mats and polymer-modified asphalt to better absorb impact without breaking.
- Reinforced structure: Impact-resistant shingles have a stronger fiberglass mat that resists tearing
- Better adhesion: Enhanced granule adhesion prevents the protective top layer from washing away
- Flexibility: Polymer modifications allow the shingle to flex rather than crack when struck
Many major manufacturers like Owens Corning and GAF offer Class 4 rated shingles that perform significantly better in hailstorms than standard options.
2. Metal Roof Hail Resistance And Performance
Metal roofs, especially steel roofing, rank among the best roof for hail storms due to their durability. While hail may cause cosmetic denting, metal roofs rarely leak as a result of hail impact.
Steel roof hail damage typically appears as shallow dents rather than punctures or tears. The thicker the metal (measured by a lower gauge number), the better it resists denting from hailstones.
Aluminum and copper roofing materials dent more easily than steel but still maintain their water-shedding ability after most hailstorms. This makes metal roofing a practical long-term investment in hail-prone areas.
- Functional vs. cosmetic damage: Metal roofs may show dents but rarely leak after hail
- Material thickness matters: 24-gauge steel resists denting better than 29-gauge
- Texture helps hide damage: Textured finishes make dents less noticeable than smooth surfaces
3. Tile And Slate Against Hail
Clay and concrete tiles provide moderate protection against small hail but can crack when hit by larger stones. Their brittle nature makes them vulnerable to impact, especially as they age and become more rigid.
Slate roofing, though extremely durable against weathering, can also crack when struck by large hail. Both materials rely heavily on high-quality underlayment to prevent leaks if the surface material becomes damaged.
Despite these vulnerabilities, properly installed tile and slate roofs with good underlayment systems can still provide effective protection. If individual tiles break, they can be replaced without requiring a full roof replacement.
4. Hail Proof Roofing With Synthetic Options
Synthetic roofing materials represent some of the most advanced hail proof roofing options available today. These products, often made from rubber or polymer composites, combine flexibility with impact resistance.
Many synthetic roofing products achieve Class 4 ratings while mimicking the appearance of slate, shake, or other traditional materials. Their ability to absorb impact without cracking makes them excellent choices for hail-prone regions.
- Flexible composition: Synthetic materials flex rather than crack when struck
- Consistent performance: Unlike natural materials, synthetic products have uniform thickness and strength
- Lower weight: Most synthetic options weigh less than natural slate or tile, reducing structural requirements
How Different Roof Types Perform Against Large Hail
Large hailstones (1.5+ inches in diameter) challenge even the most durable roofing materials. Impact from these larger stones creates more force and can cause significant damage.
Standard asphalt shingles typically suffer the most damage from large hail, with visible granule loss, cracking, and exposed fiberglass mats. Metal roofing shows more pronounced denting but usually maintains its water-shedding ability.
Tile and slate materials may crack or shatter when hit by large hailstones, especially if they’re older or improperly supported. Synthetic materials generally perform best, absorbing impact with minimal visible damage.
Best Roof Material For Hail Versus Budget Considerations
When selecting the best roof material for hail, consider both initial cost and long-term value. Higher-quality materials typically cost more upfront but may save money through fewer repairs and replacements.
impact-resistant asphalt shingles cost about 10-20% more than standard shingles but last significantly longer in hail-prone areas. Metal roofing has a higher initial price but can last 2-3 times longer than asphalt products.
Many insurance companies offer premium discounts for homes with Class 4 rated roofing materials. These discounts can help offset the higher initial cost of hail-resistant roofing over time.
Signs Your Roof May Need Replacement
After a hailstorm, check your roof for damage that might require repair or replacement. Certain visual cues indicate potential problems that could worsen if left unaddressed.
Watching For Granule Loss And Cracks
On asphalt shingles, look for areas where protective granules have washed away, leaving bald spots or exposed fiberglass mat. These areas appear darker or different in texture than undamaged portions of the roof.
Circular cracks or dents often indicate direct hail impact. Multiple impacts in the same area can weaken the roofing material and lead to leaks over time.
- Granule loss: Dark spots or areas where the protective top layer is missing
- Impact marks: Circular or star-shaped cracks around points of impact
- Exposed fiberglass: White or light-colored areas where the underlying mat shows through
Checking For Ceiling Leaks After Storms
Interior water stains or damp spots on ceilings and walls may indicate roof damage from hail. These signs often appear after rain that follows a hailstorm.
Check your attic for water stains, damp insulation, or visible light coming through the roof deck. These conditions suggest that hail damage has compromised your roof’s water-shedding ability.
Prompt inspection after hailstorms helps identify damage before it leads to more extensive problems. Even small leaks can cause significant interior damage if left unrepaired.
Steps To Ensure Your Roof Is Hail Proof
Taking proactive measures helps maximize your roof’s resistance to hail damage. These steps focus on proper material selection, quality installation, and regular maintenance.
Schedule An Inspection For Hail Proof Roofing

Amstill Roofing offers free roof inspections to homeowners in Houston and surrounding areas. These inspections help determine whether your current roof provides adequate protection against hail or if improvements would be beneficial.
Confirm Proper Installation And Underlayment
Even the best hail proof roof shingles perform poorly if improperly installed. Correct nailing patterns, proper overlap, and appropriate flashing details all contribute to a roof’s hail resistance.
High-quality underlayment provides a secondary water barrier if surface materials become damaged. This extra layer helps prevent leaks even if hail cracks or dislodges the outer roofing material.
- Proper fastening: Correctly placed nails or fasteners improve impact resistance
- Quality underlayment: Synthetic or rubberized underlayment provides better protection than felt
- Adequate ventilation: Proper attic ventilation helps reduce heat buildup that can weaken roofing materials
Upgrade To Best Shingles For Hail
When replacing your roof, consider upgrading to Class 4 impact-resistant materials. These products cost more initially but provide superior protection in hail-prone areas.
Metal roofing and synthetic materials typically offer the best hail resistance, followed by impact-rated asphalt shingles. All three options provide significant improvements over standard roofing materials.
Review warranty terms carefully when selecting new roofing materials. Some manufacturers specifically exclude or limit coverage for hail damage, while others offer enhanced protection against impact damage.
