Only GAF Master Elite contractors can register the Golden Pledge Limited Warranty, the strongest residential roofing warranty available. Standard installers, regardless of experience, cannot offer this level of coverage to homeowners. For NH homeowners evaluating the best roofing materials and the contractor who installs them, Master Elite certification is the most important credential to verify.
What NH Homeowners Need to Know About GAF Master Elite
- Certification Requirements: GAF Master Elite status requires demonstrated business longevity, full insurance coverage, strong customer reviews, and ongoing technical training. Less than 3% of US roofing contractors meet all four requirements.
- Warranty Access: A GAF Master Elite contractor is the only type of contractor who can register a Golden Pledge Limited Warranty for a homeowner. This warranty covers workmanship for 25 years and is not available from non-certified installers.
- System Installation: Master Elite contractors install complete GAF roofing systems including Timberline HDZ shingles, leak barrier, deck protection, starter strip, ridge cap, and Cobra attic ventilation components. Each component is engineered to work together and must be installed in manufacturer-specified order.
- Ventilation Expertise: Proper ventilation is a required element of a GAF system installation. It shifts warm air out continuously, reduces condensation that leads to mold, and keeps insulation in good condition throughout a New Hampshire winter.
- President’s Club Status: The GAF Master Elite President’s Club award goes to top performers within the Master Elite group each year. Coastal Windows & Exteriors has earned that recognition for seven consecutive years.
- Financial Protection: Asphalt roof replacement in New England averages $35,701, with a 68% return on investment at resale. Working with a GAF Master Elite contractor ensures that investment is protected by the strongest warranty and installation standard available.
