The warranty

A warranty you can hand a homeowner.

WeatherLok is a 60-year system. The warranty stands behind the roof, not just the first year, and it is written so a builder can pass it straight to the homeowner at closing.

It covers the ratings shown on this page. The transferable terms are confirmed directly from the warranty document, and the full document is available on request so you can read every line before you spec it.

Certifications & approvals

Independently tested. Verified before published.

WeatherLok is independently tested to 110 mph wind, Class 4 hail (UL 2218), and Class A fire. Formal code-approval numbers, ICC-ES, Florida Product Approval, and Miami-Dade NOA, are published here as each report is issued. We list a rating only when the issued report backs it.
