Common Questions

Quick Answers.

Preferred is the entry tier — most installers can qualify. Platinum Preferred is the elite tier with stricter requirements: customer satisfaction scores, ongoing training, financial verification, and annual review. Less than 1% of contractors carry it.

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.
