Typically 15-25% more than standard shingles, but insurance discounts often make them cost-neutral or even cheaper over time. We'll help you calculate your specific ROI.

Are Class 4 shingles worth it in Austin?

Absolutely. Central Texas sees frequent hail storms, and Class 4 shingles both protect your roof and reduce your insurance costs. Most of our customers choose Class 4 for this reason.

Most Texas insurers offer 10-28% premium discounts for Class 4 shingles. Some customers save $500-$1,500 per year. We recommend calling your insurer before installation to confirm.
