Choosing a roofer comes down to credentials, experience, insurance, warranties, and communication quality. Coastal Windows & Exteriors checks each of those boxes as a GAF Master Elite roofing contractor and a woman-owned exterior remodeling company, with 7,000+ installations completed since 2011 across 730+ towns in Massachusetts, New Hampshire and Maine.
Homeowners should research thoroughly before selecting a contractor—the right roofer protects your investment for decades.
Here’s how to select a quality roofing contractor:
- Manufacturer Certifications — GAF Master Elite require top-tier contractors. These certifications require training, inspections, and performance standards. Certified contractors offer enhanced warranties.
- Insurance Verification — Request certificates for liability and workers’ compensation coverage. Call insurers directly to verify policies are active and adequate. Uninsured contractors create serious liability risks.
- Local Presence — Established local companies have reputations to protect. Out-of-town storm chasers may disappear after problems arise. Choose contractors with permanent local offices.
- Written Estimates — Detailed quotes itemize materials, labor, and specific scope. Vague estimates lead to surprise charges. Compare at least three written quotes.
- Reference Checks — Quality contractors provide recent local references gladly. Actually call references and ask specific questions. Drive by completed projects when possible.
- Communication Quality — Responsive contractors answer questions clearly and promptly. Poor communication during sales indicates worse service later. Trust your instincts about professionalism.
When searching for a roofing contractor, credentials and local presence matter the most!
Top Recommendations for Choosing a Roofer
- Best Overall: Choose GAF Master Elite or equivalent certified contractors with strong local track records.
- Best Verification: Online reviews plus direct reference calls provide complete pictures of quality.
- Worst Approach: Selecting based solely on lowest bid. Poor workmanship costs more than initial savings.
