A GAF Certified Roofing Contractor You Can Trust
D & H Roofing is proud to be GAF Certified — and Certified Plus — bringing factory-trained quality and enhanced warranty protection to every Gainesville-area roof.
When you hire a roofing contractor, credentials matter. D & H Roofing is a GAF Certified (Certified Plus) contractor — a factory certification held by only a limited share of roofers. GAF is North America’s largest roofing manufacturer, and their certification tells you our work meets the standards their roofing systems are engineered to.
Combined with being family-owned, fully licensed and insured, and backed by over 20 years of experience, our GAF status means you get a roof installed the right way — and protected the right way.

GAF Certification FAQs
What does GAF Certified mean?
GAF is North America’s largest roofing manufacturer. A GAF Certified contractor has been vetted by GAF and is authorized to install GAF roofing systems to factory standards — and to offer enhanced manufacturer warranties. Only a limited percentage of roofing contractors earn this factory certification.
Is “Certified Plus” better than standard certification?
Yes. GAF Certified Plus is a higher recognition tier that allows the contractor to offer stronger, longer manufacturer warranty coverage on qualifying roof systems. D & H Roofing is GAF Certified Plus.
Does GAF certification come with a warranty?
Certification itself is a credential, but it unlocks access to enhanced GAF manufacturer warranties on qualifying installations — coverage that non-certified contractors cannot offer. Ask us which warranty options fit your project.
