If you’re tired of products that don’t live up to their names, learning what an impact-resistant roof is should brighten your day. The impact-resistant roof does what it promises, resisting damage from hail, falling branches, and high wind. It’ll even stand up to the occasional stray golf ball if you live near a local golf course. We’ll discuss the pros and cons of installing an impact-resistant roof.

What Is an Impact-Resistant Roof and Who Needs One?

So, what is an impact-resistant roof? Impact-resistant roofing consists of materials with a design made to withstand damage. They can look like other common roofing materials, but they defy damage from storms better than traditional shingles. They can withstand hail stones from severe thunderstorms, debris from windstorms, and other items that may fall on your roof.

Do you need an impact-resistant roof? If you live in an area that often has severe storms, you will receive benefits versus a roof consisting of standard materials. You may even save money on your insurance premiums by installing this kind of roof. If you think your roof might be at risk during the next storm, call a local emergency roofer for an assessment.

How Does an Impact-Resistant Roof Work?

Two testing organizations—Underwriters Laboratories and FM Approvals—provide durability ratings for all roofing materials, including impact-resistant materials. During testing, the organizations drop steel balls or ice balls onto the shingles from varying heights and then measure the damage.

Shingles come in four classes:

  • Class 1: Can withstand steel balls 1.25 inches in diameter from a height of 12 feet

  • Class 2: Can withstand steel balls 1.5 inches in diameter from a height of 15 feet

  • Class 3: Can withstand steel balls 1.75 inches in diameter from a height of 17 feet

  • Class 4: Can withstand steel balls 2 inches in diameter from a height of 20 feet

Shingles that receive a Class 4 designation are the most impact-resistant, while Class 1 is the least impact-resistant. To be considered impact-resistant, the roofing materials must have a Class 4 designation, although some brands may market themselves as impact-resistant with a Class 3 designation.

What Materials Work As an Impact-Resistant Roof?

Multiple kinds of materials can qualify for designation as an impact-resistant roof, including:

  • Asphalt shingles

  • Metal

  • Concrete

  • Plastic

  • Resin

  • Rubber

The most common impact-resistant roofing materials are either asphalt shingles or metal, although the other materials also deliver good results. Not all roofers are able to source or install every potential impact-resistant roof material.

Pros and Cons of an Impact-Resistant Roof

Although the impact-resistant roof is able to stand up to hail and other types of damage, it does carry a higher cost than standard roofing materials. Here are the pros and cons of an impact-resistant roof.

ProsCons
Limits storm damageCostlier up front
Protects from leaksSome design limits
Lower insurance costHeavier materials
Fewer repairs neededTougher to install

Is an Impact-Resistant Roof Worth It?

You’ll often pay a premium of 10% to 20% for impact-resistant asphalt shingles versus standard shingles. You also could choose to install a metal roof, which is a naturally impact-resistant material. However, metal roofs cost more than asphalt roofs for the materials and installation.

If you have a home or business property insurance policy with a high deductible, your impact-resistant roof may survive a hail storm that other roofs don’t. This means you don’t need to replace it and can save the deductible amount. 

The Insurance Institute for Business & Home Safety estimates people who live in areas with frequent thunderstorms must replace their shingle roofs an average of every seven to 10 years because of storm damage. Without damage, a shingle roof’s average life span is about 25 to 30 years. Having an impact-resistant roof could save you from having to pay the deductible once or twice every roughly 30 years.

If you don’t live in an area that has hail storms, though, the extra cost of the impact-resistant roof probably isn’t worth it. A local roofing company can advise on what the impact-resistant roof will cost to install and whether these materials are a good value for your location.

Are Impact-Resistant Shingles Worth It?

Impact-resistant shingles are more expensive than standard ones, but they’re often worth the added investment if you live in an area that sees extreme weather. You can expect to pay between 10% and 20% more for the materials, but you stand to avoid expensive roof damage over the life of the product.

When you consider the average cost to repair hail damage on a roofaround $4,250—it’s easy to see how paying more up front for your shingles can save you money. You’ll be less likely to need roof repairs or a full roof replacement after hail damage or another severe weather event. 

Frequently Asked Questions

You can check beneath your shingles to see if they’re listed as Class 4 or Class 3. Class 4 are technically the only shingles considered impact-resistant, but Class 3 shingles are still fairly resistant.

Yes, impact-resistant roofs can lower your homeowners insurance. Some insurance companies offer discounts or reduced rates if you use Class 4 or Class 3 shingles.

The lifespan of an impact-resistant roof averages 30 to 50 years, depending on the quality of the shingles and the amount of wear and tear it endures. Some high-quality shingles may last even longer. For comparison, a standard asphalt roof lasts about 20 years, so choosing an impact-resistant option can increase your roof's lifespan by 50% or more, particularly in regions prone to extreme weather.
