Roof Replacement Using Class 4 Impact-Resistant Shingles

Wisconsin and Minnesota homeowners are all too familiar with storm damage repair due to the effects of hail on their homes. When it comes time for storm damage roof repair or roof replacement, homeowners should carefully research both the roofing contractor they hire and the roofing materials that will be installed on their home.

For homeowners in areas where severe weather and hail are common, Class 4 impact-resistant shingles are an option worth understanding. These asphalt shingles are designed and tested to withstand greater impacts than standard shingles.

What Are Class 4 Impact-Resistant Shingles?

Homeowners considering a new roof installation should understand that asphalt shingles can receive different impact-resistance classifications. Class 4 is the highest impact-resistance classification under the UL 2218 testing standard.

During impact testing, steel balls of different sizes are dropped onto roofing materials to evaluate how well the shingles resist cracking, splitting, and other damage. To achieve a Class 4 rating, the roofing material must meet the requirements of the test without showing specified types of damage.

A Class 4 rating does not mean a roof is hail-proof. Actual hail damage can depend on several factors, including hail size and density, wind speed, roof age, installation quality, and the severity of the storm.

Do Class 4 Impact-Resistant Shingles Help Protect Against Hail Damage?

Class 4 impact-resistant shingles are designed to provide greater resistance to impacts than standard asphalt shingles. For homeowners in Minnesota and Wisconsin, where hailstorms can cause significant roof and exterior damage, that additional impact resistance can be an important consideration when choosing a new roofing system.

However, even an impact-resistant roof should be professionally inspected after a significant hailstorm. A roof inspection should evaluate more than the shingles. Flashing, vents, gutters, siding, and other exterior components can also sustain storm damage.

How Did GAF Impact-Resistant Shingles Perform After a Wisconsin Hailstorm?

Real-world performance can help homeowners understand why roofing material selection matters.

Lindus Construction installed GAF Timberline® ArmorShield® II impact-resistant shingles on a home in Western Wisconsin. After a major hailstorm moved through the area, the home’s gutters and siding sustained hail damage. When our team inspected the roof, the impact-resistant shingles did not require replacement.

This project demonstrates an important distinction for homeowners comparing roofing materials. Impact-resistant shingles cannot guarantee that hail will never damage a roof, but choosing a roofing system designed for greater impact resistance can provide an additional layer of protection during severe weather.

Are Class 4 Shingles Hail-Proof?

No. Class 4 shingles are impact-resistant, not hail-proof.

A Class 4 rating indicates that the roofing material successfully completed a standardized impact-resistance test. It does not guarantee that the shingles will withstand every hailstorm without damage.

Hail size, wind speed, roof slope, roof age, installation quality, and other storm conditions can all affect how a roof performs. That is why homeowners should have their roof inspected after a significant hail event rather than assuming damage has or has not occurred.

What Class 4 Asphalt Shingles Does Lindus Construction Install?

GAF Timberline® AS II Shingles

Lindus Construction offers GAF Timberline® AS II shingles for homeowners looking for a Class 4 impact-resistant asphalt roofing option.

Timberline® AS II shingles combine the dimensional appearance of an architectural shingle with impact-resistant construction designed for homes in areas where hail and severe weather are concerns.

When comparing impact-resistant roofing options, homeowners should look beyond the shingle itself. The roofing system, proper installation, attic ventilation, flashing, underlayment, and contractor workmanship can all affect the long-term performance of the roof.

What Should Homeowners Know About Class 4 Impact-Resistant Shingles and Insurance?

The most expensive home improvement can be the one you have to pay for twice. Even when insurance is involved, hail damage roof repair can still create significant out-of-pocket costs for homeowners.

Insurance policies, deductibles, and roof coverage can vary significantly by insurance company and policy. Homeowners should review their own policy and speak directly with their insurance provider to understand how hail damage, roof age, deductibles, and impact-resistant roofing materials are handled.

Some insurance companies may also offer discounts for homes with qualifying impact-resistant roofing materials. Homeowners should verify eligibility and requirements directly with their insurance carrier.

What Warranty Is Available With GAF Impact-Resistant Roofing?

A roofing warranty should protect more than the shingles themselves. Homeowners should understand whether materials and labor are covered, whether coverage becomes prorated over time, and how long workmanship is protected.

On qualifying GAF asphalt roofing systems, Lindus Construction offers the GAF Golden Pledge® Limited Warranty, including options that provide 50 years of non-prorated coverage on both labor and materials.

That type of warranty protection can be especially important because even high-quality roofing materials depend on proper installation and a complete roofing system that works together correctly.

Are Class 4 Impact-Resistant Shingles Worth It?

For homeowners in Minnesota and Wisconsin, Class 4 impact-resistant shingles may be worth considering because of the region’s exposure to hail and severe weather.

When deciding whether impact-resistant shingles are right for your home, consider:

• The frequency of hail and severe weather in your area
• The age and condition of your existing roof
• The impact-resistance rating of the roofing material
• The quality of the complete roofing system
• Installation and workmanship standards
• Warranty protection
• Potential insurance considerations

The right roofing system should be selected based on your home, budget, long-term plans, and the conditions the roof is likely to face.
