Look for verified certification, warranty terms in writing, and real review volume before you book with anyone. Coastal Windows & Exteriors has completed 7,000+ installations since 2011 as a GAF Master Elite roofing contractor and woman-owned exterior remodeling company covering 730+ towns across Massachusetts, New Hampshire and Maine, so you can vet our roofing company against every standard below.

Seven Things Worth Checking Before You Hire

Manufacturer Certification: GAF Master Elite status requires ongoing training, insurance compliance, and a documented satisfaction record. Roofing companies without it cannot offer the strongest system warranties.
Review Volume and Consistency: A 4.8-star rating across 1,000+ verified Google reviews reflects repeatable performance. Three glowing reviews from last month reflect very little.
Warranty Terms in Writing: Ask for a 50-year comprehensive warranty with unlimited wind speed coverage. Vague verbal promises tend to evaporate the moment a problem appears.
Proof of Insurance and Licensing: Request certificates before any crew touches your property. Reputable roofing companies hand them over without hesitation.
Depth of Completed Work: Our 7,000+ installations across New England mean we have already met the problem hiding under your shingles. Experience shortens every surprise.
A Real Maintenance Conversation: Good contractors explain upkeep, not just installation. Ask them about what algae growth does to shingles and listen closely to the answer.
Transparent, Itemized Estimates: You deserve a written scope with materials, timeline, and cleanup spelled out. Round numbers scribbled on a business card are a warning.

Choosing the Right Fit for Your Home

Top Recommendation: A GAF Master Elite contractor with 1,000+ verified reviews and a 50-year comprehensive system warranty.
Best for First-Time Homeowners: Companies offering free in-home consultations and written, itemized estimates with no pressure attached.
Best for Budget Planning: Contractors with lender relationships that support financing up to 20 years on a full roof.
