Coastal Windows & Exteriors is a GAF Master Elite contractor serving 730+ towns across Massachusetts, New Hampshire and Maine with 7,000+ installations completed since 2011. When choosing a roofing company, look for verified credentials and a strong warranty.

Qualities That Define a Trustworthy Roofer

GAF Master Elite certification comes first: This status belongs to only 2% of contractors nationwide. It demands training, insurance compliance, and consistent homeowner satisfaction.
Review volume signals a track record: Look for a roofer with 1,000+ verified reviews and a 4.8-star rating. Volume plus consistency points to dependable work.
Strong warranties protect your investment: Top crews back their work with a 50-year comprehensive warranty. Unlimited wind speed coverage marks a serious roofing company.
Twice-yearly inspections show real care: A quality roofer helps you inspect in spring and fall. That habit catches small issues before they grow into costly repairs.
Financing reflects stability: A company offering financing up to 20 years holds solid lender relationships. That backing signals a business built to last.
Local experience matters: Our team has completed 7,000+ installations. That depth shows in every project we finish.

How to Compare Roofers

Top Recommendation: A GAF Master Elite roofing contractor with 1,000+ reviews and a 50-year warranty.
Best for Budget: A crew offering transparent, itemized estimates and flexible financing.
Best for High-Value Homes: An award-winning company with a proven record on lakefront properties.
