If you're replacing a roof in hail country, the question comes up fast: should you pay extra for Class 4 impact-resistant shingles?
What Class 4 means
UL 2218 Class 4 is the highest rating in a standardized test that drops steel balls on roofing. It measures resistance, not immunity.
The math
- Expect a moderate premium over standard architectural shingles. See our cost guide
- Many Texas insurers offer a premium discount for Class 4 roofs. Get the actual figure from your agent
- Keep the manufacturer certificate and invoice to prove the rating
Caveats
- Some insurers limit cosmetic-damage coverage on impact-resistant roofs
- Installation quality still matters most for leaks
