Common Questions

Quick Answers.

It means we're an authorized member of Owens Corning's contractor network — vetted on licensing, insurance, and installation standards, and factory-trained on OC's full Total Protection Roofing System. That status is what lets us register your install for OC's System Protection warranty package, instead of just a basic shingle-only warranty.

Both are top-tier. GAF Timberline HDZ is our most-installed shingle and the industry standard. OC Duration with SureNail technology has the strongest wind warranty and a slightly different look. We help you decide based on your home, budget, and color preferences.

It's a coordinated system of OC components: Duration shingles, ProArmor synthetic underlayment, WeatherLock ice & water shield, VentSure ridge vents, and Starter and Hip & Ridge accessories. Engineered to work together — not mix-and-matched parts.
