What the badge means
Certified by the largest roofing manufacturer in North America
GAF certification isn't handed out — it's earned through verified licensing, insurance, and a track record of quality installations. For you, it means the crew on your roof is factory-trained and your new roof can qualify for enhanced GAF warranty coverage that non-certified contractors can't offer.
