Hiring a certified roofer protects your home, your warranty, and your long-term investment. Coastal Windows & Exteriors is a GAF Master Elite roofing contractor and woman-owned exterior remodeling company serving 730+ towns across Massachusetts, New Hampshire and Maine with 7,000+ installations completed since 2011, and certification means rigorous training, proper insurance, and proven accountability.

What Certification Actually Means for Your Roof

GAF Master Elite Status Is the Gold Standard: Only 2% of roofing contractors nationwide hold this certification. It requires customer satisfaction history, insurance verification, and ongoing professional development.
Manufacturer Warranties Require Certified Installers: GAF’s strongest warranties — including 50-year comprehensive coverage with unlimited wind speed protection — are only available through certified contractors like Coastal Windows & Exteriors.
Insurance Compliance Protects You: Certified roofers carry full liability and workers’ compensation coverage. That protects your home and your finances if anything goes wrong on-site.
Training Translates Into Better Workmanship: Certified crews install the GAF 6-layer system in precise sequence. Even small installation shortcuts can compromise an entire roof’s performance over time.
Accountability Beyond the Sale: Certified contractors are subject to manufacturer oversight. A certified company can’t simply walk away from a problem job without consequences.
A Certified Team Saves You Money Long-Term: Roofs installed by certified contractors typically need fewer repairs and last closer to their full lifespan. Cheaper labor often costs more across 20 years.
Roofs for Heroes Reflects Our Values: Coastal Windows & Exteriors received an honorable mention Minuteman Service Award for our Roofs for Heroes initiative — a program serving those who serve our country.

Our Recommendations for Homeowners

Top Recommendation: Hire a GAF Master Elite-certified roofer with 1,000+ verified reviews for the strongest combination of skill and accountability.
Best for Warranty Protection: Certified contractors offering manufacturer-backed 50-year warranties with unlimited wind speed coverage.
Best for Complex Roof Projects: Award-winning certified roofers with experience on dormers, valleys, and multi-pitch designs.
