GAF Master Elite certified roofing contractors represent the top 2% of roofers in North America. You get access to stronger warranties and a higher standard of workmanship. For homeowners throughout Sullivan County, knowing what to look for makes the difference between a roof that lasts and one that fails early.
What to Look for When Hiring a Roofer in the Dartmouth-Lake Sunapee Region
- Certification matters: GAF Master Elite certification requires contractors to meet strict standards for training, reputation, and ongoing accountability. This status is earned, not purchased — and it’s the clearest credential to ask about before hiring.
- Verify insurance first: Any contractor working on your home must carry both general liability insurance and workers’ compensation coverage. Always request proof of both before signing any agreement or allowing work to begin.
- Understand the full system: A qualified contractor should be able to explain what is a roofing system. This includes deck protection, leak barriers, ventilation, ridge cap, and starter strips — before any work begins on your home.
- New England shingle experience: In Western NH, contractors need direct experience with New England shingle products built to handle ice dams, heavy snow loads, and repeated freeze-thaw cycles. Regional knowledge is not optional here.
- Check for red flags: Pressure to decide quickly, requests for large cash deposits upfront, or reluctance to pull permits are warning signs. Emergency roof leak repairs can cost up to twice as much as planned repairs.
- Inspection history matters: According to GAF, homeowners near the Vermont border and throughout the Upper Valley should inspect roofs at least twice yearly — spring and fall. A trustworthy contractor will recommend this proactively, not avoid the conversation.

Worth confirming: That your contractor provides a written scope of work, pulls the appropriate permits, and can explain every layer of the roofing system before installation begins.
Avoid entirely: Any contractor who can’t show proof of insurance, won’t discuss permits, or pushes you to sign before you’ve had time to think.
