Why should I hire a GAF certified roofing contractor?

Hiring a GAF certified roofing contractor ensures you receive superior warranties, factory-trained installation, and verified quality standards.

Franklin homeowners who choose certified contractors gain coverage that non-certified installers simply cannot offer.

Here’s what GAF certification delivers:

Enhanced Warranty Coverage — GAF Master Elite contractors can offer Golden Pledge warranties covering materials AND labor for 25 years with 50-year material coverage. Non-certified installers offer only limited material warranties without workmanship protection.
Factory Training — Certified contractors complete ongoing training on proper installation techniques. Correct underlayment layering, flashing details, and ventilation requirements directly affect how long your roof lasts.
Verified Business Standards — GAF certification requires proper licensing, insurance, and proven reputation. You’re hiring contractors who’ve been vetted by the manufacturer, not just whoever offers the lowest bid.
Exclusive Products — Certain high-performance products are only available through certified installers. Access to complete roofing systems means better protection than mix-and-match component installation.
Accountability — GAF backs certified contractor work. If issues arise, you have manufacturer support beyond just the contractor’s promise. This matters if contractors change ownership or go out of business.
Fewer Than 3% Qualify — GAF Master Elite status represents the top tier of roofing contractors. Rigorous requirements mean you’re choosing from proven professionals, not the entire contractor population.

GAF Certification Overview

Best Overall: Choose GAF Master Elite contractors for maximum warranty protection and proven quality.

Best Value: The cost difference for certified installation is minimal compared to warranty value over 25+ years.
