Expert Verdict — Reviewed by the SuperArbor Pro Desk

Choose Duration STORM where hail is a concern or insurers offer Class 4 credits; the WeatherGuard backing is what separates it from standard Duration shingles. Register the System warranty and use matching OC starter and hip & ridge to preserve the 160 MPH wind rating and Class 4 system coverage. Verify color on an actual sample or installed roof, since monitors vary.

Install per the manufacturer's installation instructions and local building code, and use proper fall protection when working on steep-slope roofs.
