Class 4 Impact Resistant
Roofing — Save 18–32%
On Insurance Per Year
In Indiana, Illinois, and Michigan's hail corridor, upgrading to Class 4 UL 2218 shingles is one of the highest-ROI investments a homeowner can make. The $800–$1,400 upgrade premium recovers in 12–18 months through annual insurance savings — then generates $800+ per year in net savings for the life of the shingles. One contractor. Free estimate. Carrier discount confirmed before materials are ordered.
What Is a Class 4 Impact-Resistant Shingle?
UL 2218 is the roofing industry's hail impact resistance rating system. Class 4 is the highest rating — achieved by passing a test that no standard architectural shingle can pass: a 2-inch steel ball dropped from 20 feet onto the same spot twice, with no cracking or substrate penetration.
The UL 2218 Test
2" steel ball. 20-foot drop. Same spot twice. No cracking permitted. Standard architectural shingles fail at Class 1 or 2. Class 4 is the maximum rating.
Four Rating Classes
Class 1 (1" ball) · Class 2 (1.25") · Class 3 (1.5") · Class 4 (2"). Only Class 3 and 4 qualify for most insurance discounts. Class 4 gets the highest discount tier.
Extended Service Life
Class 4 resists the granule loss that shortens standard shingle life. Achieves 28–35 effective years in high-hail markets vs. 18–22 for standard architectural.
Same Installation
Class 4 shingles install identically to standard architectural. Same tools, same process, same roofing system. The difference is material composition only.
What Is the Financial Return on Class 4 Shingles?
The math is straightforward — and your matched contractor confirms your carrier's actual discount rate before materials are ordered so the ROI is locked in before you commit.

Which Insurance Carriers Offer Class 4 Discounts?
Always confirm with your agent before ordering materials. Discount percentages vary by state, county, home age, and deductible. Get the confirmation in writing — by email from your agent — before your contractor orders shingles.
What Do Homeowners Say After Upgrading to Class 4 Shingles?
"The contractor confirmed our Indiana Farm Bureau discount before ordering anything. We got 28% off our annual premium — $896 per year savings. The upgrade cost us $1,100 more than standard shingles. We broke even in 15 months. Now it's pure savings every year for the next 30 years."
Brad & Susan H. — Greenwood, IN · Class 4 with IFB 28% discount · March 2026
"We had hail damage twice in 6 years. The second time we upgraded to Class 4 during the insurance replacement. The contractor provided the Certificate of Installation — State Farm applied a 22% discount at the next renewal. Haven't had a claim since. The shingles are genuinely different."
Nicole A. — Schaumburg, IL · Class 4 after second hail claim · December 2025
"I was skeptical about the ROI claim. The contractor showed me the actual carrier form, confirmed my Erie Insurance rate, and calculated the exact payback. 19 months. I asked my agent the next day and she confirmed the discount. Everything the contractor said was accurate."
