As the DFW metroplex moves through the secondary storm season, roofing contractors are observing the real-world performance of Class 4 impact-resistant (IR) shingles. These materials are tested using the UL 2218 standard, which involves dropping steel balls to simulate hail strikes.
Recent inspections across North Texas indicate that while IR shingles do not make a roof 'hail-proof,' they significantly reduce the likelihood of functional damage. Functional damage involves the fracturing of the fiberglass mat, which leads to leaks.
Long-term Value
Homeowners opting for these materials typically see a reduction in insurance premiums. Most major carriers in Texas offer discounts ranging from 10% to 25% for verified Class 4 installations.
- Reduced risk of granular loss
- Lower probability of emergency repairs after mid-sized storms
- Potential for higher resale value
Property owners should ensure their contractor provides a Certificate of Installation for their insurer to secure these rate reductions.
