Why Your Clients Will Love Class 4 Impact-Resistant Shingles

As a contractor, you’re always looking for ways to bring more value to your clients—whether through durability, curb appeal, or smart long-term investment. One product that checks every box? Class 4 impact-resistant shingles.

These high-performance shingles are designed to withstand the harshest weather conditions, from wind-driven hail to falling branches, making them an ideal upgrade for homeowners across Western PA and beyond. At CGR Wholesale, we supply Class 4 shingles from trusted brands like Atlas and CertainTeed so you can offer your clients roofing solutions that truly stand the test of time.

What Are Class 4 Impact-Resistant Shingles?

Class 4 is the highest rating a roofing product can receive under the UL 2218 impact test—a standardized test that drops steel balls onto the shingle surface to simulate hail impact. To earn a Class 4 rating, shingles must show no cracking, tearing, or rupturing after multiple impacts.

This rating means they provide:

• Superior hail and storm resistance

• Greater resilience to flying debris

• Reduced risk of shingle damage during high winds or storms

Why Homeowners Appreciate Class 4 Shingles

1. Storm-Resistant Peace of Mind

Western Pennsylvania sees its share of harsh weather—especially spring and summer storms. Class 4 shingles give homeowners confidence that their roof can handle impact without failing, leading to fewer emergency repairs or insurance claims.

2. Potential Insurance Discounts

Some insurance companies offer premium discounts for homes protected by Class 4 shingles, particularly in hail-prone areas. This benefit makes it easier for contractors to upsell premium products with real ROI for the homeowner.

3. Longevity & Durability

Class 4 shingles often feature advanced manufacturing processes like SBS (Styrene-Butadiene-Styrene) polymer modification or reinforced fiberglass mats. These materials help extend the roof’s overall lifespan by standing up better to wear and tear.

4. Enhanced Property Value

Installing high-performance shingles like Atlas StormMaster® Shake or CertainTeed’s IR lines adds value and marketability to a home—especially for buyers looking for low-maintenance exteriors and smart energy choices.
