When it comes to impact-resistant roofing, understanding the class 3 vs class 4 shingles insurance discount can mean the difference between leaving hundreds of dollars on the table every year or locking in real long-term savings.

What Are Impact-Resistant Shingles?

Not all shingles are created equal. The roofing industry uses the UL 2218 test to measure impact resistance.

How the UL 2218 Test Works

  • Class 1: 1.25-inch impact
  • Class 2: 1.5-inch impact
  • Class 3: 1.75-inch impact
  • Class 4: 2-inch impact

Both qualify for discounts, but Class 4 typically earns significantly higher premium reductions.

Does Every Insurance Company Offer a Discount?

Discounts vary by insurer and may require documentation.

The Cost Difference Between Class 3 and Class 4

Class 4 shingles typically cost $500–$1,500 more depending on roof size and product.
