In a time when extreme weather events are happening more frequently, more homeowners are looking for solutions to shield their properties from harm. Installing impact-resistant roofing systems is one of the best solutions. These roofs are made to endure harsh weather, such as hail, strong winds, and flying debris.
To help you out, everything you need to know about impact-resistant roofs in 2024 will be covered in this blog post.
What Is An Impact-Resistant Roof?
Impact-resistant roofs are designed to withstand extreme weather, particularly hail and powerful winds, without sustaining damage. As these roofs are designed to absorb and spread impact energy, they are a dependable option for homes in places prone to extreme weather, unlike standard roofing materials that can break, crack, or dent under stress.
Impact-resistant roofs are made of sturdy materials such as metal, asphalt, or synthetic composites. With this kind of roof, the likelihood of leaks and water damage is decreased, which can result in lower insurance costs. These roofs also typically last longer than traditional materials. Investing in an impact-resistant roof will safeguard your house, boost its longevity, and potentially raise its value.

How are Impact-Resistant Roofs Tested?
As mentioned above, a roof’s ability to withstand sudden forces, such as hail or debris, is called impact resistance. This is especially important in regions where severe weather is common. Organizations like Underwriters Laboratories (UL) and FM Approvals test roofing materials to ensure they can handle these conditions.
UL Testing Procedures
The UL 2218 test checks the impact resistance of roofing materials. In this test, steel balls of different sizes are dropped from specific heights onto the roofing materials.
1. Steel Ball Sizes
The test uses balls ranging from 1.25 inches to 2 inches in diameter, representing different hailstone sizes.
2. Drop Heights
For the highest rating, Class 4, a 2-inch ball is dropped from 20 feet.
3. Damage Check
After the test, the material is inspected for cracks or splits. To earn a high rating, the material must resist damage even after multiple impacts in the same spot.
Damage Criteria
The UL 2218 test not only checks if the material can handle impacts but also assesses the extent of damage. A Class 4 rating indicates no visible damage after testing, while lower classes might show signs of cracking or granule loss on shingles.
| CLASS | RESISTANCE LEVEL | IMPACT SIZE | DESCRIPTION |
| Class 1 | Minimal resistance | 1.25-inch ball | It may get damaged by minor hailstorms. |
| Class 2 | Moderate resistance | 1.5-inch ball | Suitable for light storms but still vulnerable to significant hail. |
| Class 3 | Good resistance | 1.75-inch ball | Handles most hail impacts without severe damage. |
| Class 4 | Exceptional resistance | 2-inch ball | Withstands severe hailstorms and large hailstones; shows no visible damage. |
Certification
Roofing materials that pass the UL 2218 test get certified as impact-resistant. This certification is important for insurance discounts and the materials are marked with the UL logo on the packaging, assuring homeowners of the roof’s quality.
FM Approvals Testing
FM Approvals uses a different method, where ice balls are launched at roofing materials placed at an angle to mimic real-world conditions. This test, known as FM 4473, checks how well the material can withstand multiple hits without getting damaged.
Wind Uplift Testing
In addition to impact resistance, some tests assess a roof’s ability to resist high winds. The wind uplift test ensures the roof stays in place during severe wind events, which is crucial for areas prone to hurricanes or tornadoes.
Types of Impact-Resistant Roofing Materials
1. Asphalt Shingles
Asphalt shingles are a common and budget-friendly roofing choice. When mixed with rubberized polymers, they become more impact-resistant. These impact-resistant roof shingles are made from fiberglass or organic materials coated with asphalt and granules, which makes them flexible and durable against harsh weather.
- Durability: Rubberized asphalt shingles resist cracking and granule loss, especially with higher ratings.
- Cost-Effectiveness: Generally cheaper than other impact-resistant materials.
- Insurance Benefits: May qualify for insurance discounts due to their hail resistance.
- Variety: Available in many colors and styles to fit different home designs.
2. Composite Shingles
Composite shingles blend asphalt, rubber, and other synthetic materials to create strong roofing shingles. They mimic traditional looks like wood or slate while offering better impact resistance. They come in various styles and are often rated Class 4, ideal for severe weather areas.
- Flexibility: Rubber content helps absorb impacts without breaking.
- Longevity: Often rated Class 4, suitable for severe weather.
- Affordability: Typically less expensive than natural materials but offers similar benefits.
- Lightweight: Easier to install than heavier materials like slate.
3. Metal Roofs
Metal roofs, made from materials like steel or aluminum, are known for their strength and long life. They can be treated for better impact resistance and are often made from recycled materials. Metal roofs can also have finishes like stone-coated steel for extra protection and a unique look.
- Longevity: Lasts 50+ years with proper care.
- Fire Resistance: Many types are Class A fire-rated for added safety.
- Wind Resistance: Highly durable against strong winds.
- Low Maintenance: Requires minimal upkeep.
4. Clay and Slate Tiles
Clay and slate tiles are durable and add a classic touch to homes. Clay tiles are made from fired natural clay, while slate tiles come from natural stone. They can last over 100 years, though they are heavier and may cost more to install.
- Natural Strength: Both types are impact-resistant, with slate being especially durable.
- Longevity: Can last over 100 years.
- Fire Resistance: Clay and slate tiles are non-combustible and fire-resistant.
