Beyond the Storm: A Guide to Class 4 Impact-Rated Roofing

The “Class 4” Performance Matrix

• The Gauntlet: To earn a UL 2218 Class 4 rating, a material must withstand a 2-inch steel ball dropped from 20 feet without cracking or fracturing the backing.
• The Reward: Homeowners in Kentucky and Ohio can see insurance premium discounts of 10% to 35% after installing certified Class 4 materials.
• 2026 Grant Opportunity: The Strengthen Kentucky Homes (SKH) program now offers grants of up to $10,000 for eligible Kentucky homeowners to fortify their roofs against wind and hail.
• The Bottom Line: In a region facing increasingly frequent “Supercell” storms, a Class 4 roof is no longer a luxury—it is a financial shield that prevents massive deductible spikes and Actual Cash Value (ACV) depreciation.

Protecting Your Asset with Impact-Resistant Technology

Your roof is your home’s first line of defense. Dealing with the aftermath of a Midwest hailstorm is more than just a repair—it’s a disruption to your life and a hit to your finances. At American Roofing and Metal, we “Love What You Do,” which means we take a personal interest in helping you choose materials that end the cycle of repeated storm claims.

1. What Does “Impact-Resistant” Actually Mean?

Not all “tough” roofs are created equal. The industry standard is the UL 2218 Class 4 test. This forensic-level evaluation simulates the impact of 2-inch hailstones hitting your roof at nearly 90 mph. While a standard architectural shingle will fracture or “bruise” under these conditions, a Class 4 rated system—often made from SBS-modified (rubberized) asphalt or rigid materials—remains watertight.

2. Material Options for High-Impact Zones

If you are tired of filing insurance claims every spring, consider transitioning to a more permanent, rigid roofing material. We offer a full suite of Class 4 solutions:

• SBS-Modified Asphalt Shingles: These “rubberized” shingles bend instead of breaking, providing the highest impact rating in a traditional look.
• Standing Seam Metal: Naturally resistant to impact and wind, metal is a “Lifetime” solution for the Ohio Valley climate.
• Synthetic Slate & Tile: High-performance polymers designed to mimic the look of historic stone with impact durability.
• Natural Slate & Stone-Coated Steel: Proven heavyweights that provide superior protection against large-diameter hail.

3. Navigating the Insurance Landscape

The insurance market in Kentucky, Ohio, and Indiana has shifted. Many carriers are moving toward Actual Cash Value (ACV) policies, which pay out less as your roof ages.

• The “Class 4” Advantage: Installing an impact-resistant roof can often help you qualify for Replacement Cost Value (RCV) endorsements, ensuring your carrier pays for the full cost of a new roof, not just a depreciated fraction.
• Substantial Credits: Most major insurers provide annual premium credits to homeowners who can provide a UL 2218 certification from their contractor.

Impact-Resistant Roofing FAQs

How do I get the “Strengthen Kentucky Homes” grant?

The SKH program began accepting applications in early 2026. To qualify, you must work with an approved contractor (like American Roofing and Metal) and install a roof that meets specific wind and hail resistance standards.

Is a Class 4 roof really worth the extra cost?

Yes. While Class 4 shingles typically cost 10% to 25% more than standard shingles, they often pay for themselves within 5–7 years through insurance premium savings and by avoiding the $1,000–$5,000 deductibles associated with storm claims.

Can “Class 4” shingles still get damaged by hail?

A Class 4 rating means the shingle did not rupture or crack through the matting. While massive hail can still cause cosmetic surface damage, the roof remains watertight, preventing the interior water damage that leads to expensive restoration.
