Excellence in every shingle, dedication to every project
A roof protects everything under it, so quality is the first thing to judge a roofer on, not an extra.
Top roofing contractors pursue certification from manufacturers like GAF, North America's largest roofing manufacturer, ensuring expertise with industry-leading materials and installation methods. Ask to see a contractor's current certificate; manufacturers issue them, and they can lapse.
Massachusetts requires contractors working on existing owner-occupied homes of one to four units to register through the Home Improvement Contractor program, and registration gives homeowners certain protections, including a state guaranty fund. Roofing work also needs a Construction Supervisor License held by someone responsible for the job. New Hampshire has no state roofing license, so there, ask for insurance certificates.
A quality job uses manufacturer-grade materials throughout. Every shingle, flashing piece, and underlayment should be chosen for durability and weather resistance, because a roof is only as good as its weakest layer.
Certified installers follow manufacturer specifications precisely. Proper installation is critical: a premium roof installed poorly won't deliver the protection it should. Ask whether the roofer photographs each stage.
No hidden fees, no surprise charges. A detailed estimate breaks down materials, labor, and timeline, and the final bill should match it.
Expect written warranty coverage on both materials and workmanship. A roofer confident in their work offers a workmanship warranty measured in years, not months.
From first inspection to final walkthrough, a careful roofer documents the job. Ask for photos, material certifications, installation records, and warranty documents to keep.
The six checks a well-run roofing job goes through
Comprehensive assessment of current roof condition, identifying damage, wear, and structural concerns.
Careful choice of premium materials matching project needs, climate, and aesthetic preferences.
Expert installation by certified technicians following manufacturer specifications precisely.
Regular inspections throughout installation confirm every detail meets the contract and the manufacturer's specifications.
Thorough walkthrough with photos documenting completion and quality of every installation detail.
Ongoing warranty coverage and maintenance guidance ensuring long-term roof performance.
A good roofer comes back to fix anything that isn't right. Ask how callbacks are handled before you sign.
Questions after installation should go to the same project manager you dealt with during the job, and they should answer quickly.
Roofers who have worked in Dracut and Lowell for years live on word of mouth, which is a good reason to ask neighbors who they used.
