Roofing Contractors Boston: License Basics
Roofing contractors in Boston must meet stricter licensing requirements than many trades. Here is what homeowners should verify before signing a reroofing contract.

Two Licenses to Check
Massachusetts roofers doing structural work need a Construction Supervisor License, while residential contractors also need Home Improvement Contractor registration for jobs over $1,000.
Both can be verified through the state's online license lookup tools before you sign anything.
Permits for Reroofing Projects
Full tear-offs and major repairs require a building permit from the City of Boston Inspectional Services Department, and inspectors typically review decking, flashing, and ventilation.
Skipping the permit step can create problems later when selling the property or filing an insurance claim.
Insurance and Contract Details
Ask for proof of general liability and workers compensation insurance, since roofing carries higher injury risk than most home improvement trades.
A solid contract should specify materials, warranty terms, and cleanup responsibilities, especially for nail and debris removal in tight urban lots.
What a Typical Boston Reroof Costs
Single-family asphalt shingle reroofs run $8,500 to $15,000, while triple-deckers with more roof area often run $12,000 to $22,000 in 2026.
Flat-roof sections common on rear additions typically use EPDM rubber membrane and cost less per square foot than pitched shingle work.
Typical cost ranges
| Single-family shingle reroof | $8,500 - $15,000 |
| Triple-decker reroof | $12,000 - $22,000 |
| EPDM flat roof section | $6,000 - $12,000 |
| Gutter replacement | $1,800 - $4,500 |
