Massachusetts has one of the most rigorous contractor licensing systems in the country. Unlike many states that require only a single license or registration, Massachusetts mandates two separate credentials for roofing contractors: the Construction Supervisor License (CSL) issued by the Board of Building Regulations and Standards (BBRS), and the Home Improvement Contractor (HIC) registration through the Office of Consumer Affairs and Business Regulation.
The CSL demonstrates that the contractor has passed an examination covering the Massachusetts Building Code (780 CMR) and is qualified to supervise construction projects. The HIC registration is a consumer protection mechanism that provides homeowners with access to the state Guaranty Fund and ensures contractors meet basic financial responsibility requirements.
Both credentials are independently verifiable through state databases at mass.gov/bbrs. Always verify both before signing any contract.
Understanding the Construction Supervisor License (CSL)
The CSL is the cornerstone of Massachusetts construction oversight. Issued by the BBRS, it certifies that a contractor understands and can apply the Massachusetts Building Code (780 CMR) to construction projects. There are two classifications that matter for residential roofing.
Unrestricted CSL
Holders can supervise any residential or light commercial construction project of any size in Massachusetts. This is the highest level of CSL and indicates the contractor has passed a more comprehensive examination.
- Multi-family buildings of any size
- Commercial roofing projects
- All single-family residential work
- No project scope limitations
Restricted CSL
Holders are limited to supervising construction on one- and two-family dwellings and certain smaller projects. This is the more common license type among residential-only roofers.
- Single-family homes
- Two-family (duplex) buildings
- Standard residential roof replacements
- Cannot supervise multi-family or commercial
For a standard single-family roof replacement, either CSL type is acceptable. If your home is part of a multi-family building or condo complex, insist on a contractor with an Unrestricted CSL.
Home Improvement Contractor (HIC) Registration
The HIC registration is Massachusetts’s primary consumer protection tool for residential construction. While the CSL ensures technical competency, the HIC registration ensures financial responsibility and legal accountability.
Who Needs It
Any person or business that solicits, undertakes, or performs home improvement work exceeding $200 in Massachusetts. This includes all roofing work — full replacements, repairs, and even significant maintenance projects.
What It Provides Homeowners
Access to the Massachusetts Home Improvement Contractor Guaranty Fund, which compensates homeowners up to $10,000 per project when a registered contractor fails to perform. Without HIC registration, you have no access to this fund.
Renewal and Continuing Education
HIC registration must be renewed periodically, and contractors must demonstrate continued compliance with insurance requirements. The CSL also requires continuing education credits to maintain. Both credentials can lapse — always verify current status, not just initial issuance.
What Massachusetts Requires from Roofing Contractors
Construction Supervisor License (CSL)
Massachusetts requires a CSL from the Board of Building Regulations and Standards (BBRS) for anyone supervising construction work including roofing. Two types exist: Unrestricted (any project size) and Restricted (limited scope, typically 1-2 family dwellings).
Home Improvement Contractor (HIC) Registration
All contractors performing residential home improvement work over $200 — including roofing — must register as a Home Improvement Contractor with the Office of Consumer Affairs. This is separate from and in addition to the CSL.
$500,000 General Liability Insurance
Massachusetts mandates a minimum of $500,000 in general liability coverage for roofing contractors — significantly higher than many other states. This protects homeowners against property damage during the project.
Workers' Compensation Insurance
Massachusetts has zero tolerance for uninsured workers on job sites. Workers' compensation insurance is mandatory for any contractor with employees. Penalties include criminal charges, fines up to $1,500 per day, and stop-work orders.
Massachusetts Building Code (780 CMR) and Roofing
The Massachusetts Building Code, codified as 780 CMR, governs all construction activity in the state including roofing. Understanding how this code affects your project helps you evaluate whether a contractor is cutting corners or following the rules.
Permit Requirements
Massachusetts requires building permits for roof replacements in all municipalities. Your contractor must pull a permit from the local building department before work begins. The permit ensures the project is inspected by a local building inspector for code compliance. Any contractor who suggests skipping the permit is breaking state law.
Ice and Water Shield
Due to Massachusetts’s harsh winters, 780 CMR requires ice and water shield membrane along all eaves, valleys, and penetrations. The membrane must extend at least 24 inches beyond the interior wall line. This is non-negotiable in Massachusetts and is a critical protection against ice dam damage.
Ventilation Standards
The code mandates adequate attic ventilation ratios to prevent moisture buildup and ice dams. A qualified contractor will assess your soffit and ridge ventilation during the estimate and recommend corrections if your current ventilation does not meet code. Improper ventilation voids most manufacturer warranties.
Wind Resistance Requirements
Massachusetts falls within wind zones that require specific shingle ratings and fastening patterns under 780 CMR. Coastal communities — including Cape Cod, the South Shore, and the North Shore — have additional high-wind requirements. Your contractor should specify which wind rating applies to your location.
How to Verify a Massachusetts Roofing Contractor
Four steps before you sign anything.
Verify the Construction Supervisor License (CSL)
Visit the BBRS online license lookup to confirm the contractor holds an active CSL. Verify whether it is Unrestricted or Restricted, and confirm it matches the contractor’s legal business name. The CSL number should appear on all contracts and permits.
BBRS License LookupConfirm HIC Registration
Separately verify the contractor’s Home Improvement Contractor registration through the Office of Consumer Affairs. The HIC registration is a different credential than the CSL — a contractor can have one without the other, and you need to confirm both are active.
Office of Consumer AffairsCall the BBRS directly if needed
If the online lookup is unclear or the contractor’s information does not match, call the Board of Building Regulations and Standards directly to confirm license status and any disciplinary history.
(617) 727-3200Verify insurance separately
Licenses and insurance are tracked independently. Request a current certificate of insurance showing at least $500,000 in general liability coverage. Call the insurance company directly to confirm the policy is active — expired or cancelled policies are a common issue. Also request proof of workers’ compensation coverage if the contractor has any employees.
Massachusetts Home Improvement Contract Requirements
Massachusetts law imposes specific requirements on home improvement contracts that go beyond what many other states require. Understanding these requirements helps you spot contractors who are not following the law.
Required Contract Elements
- Contractor’s HIC registration number
- Construction Supervisor License (CSL) number
- Detailed written scope of work
- Total price and payment schedule
- Start date and estimated completion date
- Three-day right-to-cancel notice
- Description of materials to be used
- Warranty terms and duration
Key Legal Protections
- Deposit cap: Maximum of one-third of total project cost or the cost of special-order materials
- 3-day cancellation right: You can cancel any home improvement contract within 3 business days
- Guaranty Fund: Up to $10,000 compensation per project if a registered contractor fails to perform
- Written change orders: All changes to the original scope must be documented in writing and signed by both parties
- Lien protections: Proper contract documentation helps protect against mechanic’s liens from unpaid subcontractors
7 Red Flags for Massachusetts Homeowners
These warning signs are especially common after nor’easters and severe weather events in Massachusetts.
No CSL or HIC registration number
Massachusetts roofing contractors need both a Construction Supervisor License and HIC registration. Missing either one means the contractor is operating illegally.
Refuses to show insurance certificate
Massachusetts requires $500K in general liability — far more than most states. A legitimate contractor will provide proof without hesitation.
Storm chasers after nor'easters
After heavy storms, out-of-state crews flood Massachusetts with no local license, no local presence, and no intention of honoring warranties. They collect deposits and disappear.
Demands more than one-third deposit
Massachusetts law caps deposits at one-third of the total project cost. Any contractor demanding more is violating state law.
Cash-only payment requests
Cash-only jobs leave no paper trail and make disputes nearly impossible to resolve. Always pay by check or card to maintain documentation.
No written contract provided
Massachusetts law requires written contracts for all home improvement work over $1,000 including the contractor's HIC and CSL numbers. No written contract is a violation of state law.
Pressures you to sign immediately
Massachusetts law gives homeowners 3 business days to cancel any home improvement contract. Contractors who pressure immediate commitment are hoping you waive this legal right.
How to File a Complaint Against a Massachusetts Roofing Contractor
If you have a dispute with a roofing contractor in Massachusetts, there are multiple avenues for recourse depending on the nature of the issue.
BBRS Complaint (CSL Violations)
If a contractor performed substandard work, failed to follow the Massachusetts Building Code, or operated without a valid CSL, file a complaint with the Board of Building Regulations and Standards. The BBRS has the authority to suspend or revoke a Construction Supervisor License and impose fines. Complaints can be filed online at mass.gov/bbrs or by calling (617) 727-3200.
Office of Consumer Affairs (HIC Violations)
For issues related to contract violations, failure to perform, or deceptive business practices, file a complaint with the Office of Consumer Affairs. This is also where you apply for compensation from the Home Improvement Contractor Guaranty Fund, which covers losses up to $10,000 per project caused by registered HIC contractors.
Attorney General’s Office
For cases involving fraud, significant financial harm, or unlicensed contracting, the Massachusetts Attorney General’s Consumer Protection Division can investigate under Chapter 93A — the state’s consumer protection statute. Chapter 93A allows courts to award treble (triple) damages for willful or knowing violations, making it a powerful tool for homeowners.
Why RoofVista Pre-Vets Every MA Contractor
Massachusetts’s dual-credential system (CSL + HIC) is a strong baseline — but credentials alone do not tell you whether a contractor does quality work, carries adequate insurance above the minimums, or has a track record of completing roofing projects on time and on budget. RoofVista goes further so you can compare standardized quotes with confidence.

We confirm every contractor holds both an active Construction Supervisor License from the BBRS and a current HIC registration with the Office of Consumer Affairs before they join the marketplace.
Insurance Coverage Confirmed

Project History Reviewed
Only contractors with verified completed projects and positive customer ratings in Massachusetts are accepted. We review workmanship quality, timeline adherence, and communication.
MA Business Presence Required
Every contractor must maintain an active Massachusetts business address and demonstrate established local operations. Out-of-state storm chasers are screened out at onboarding.
How Massachusetts Compares to Neighboring States
Massachusetts has stricter licensing requirements than most of its neighbors. Here is how the Bay State stacks up.
| Requirement | Massachusetts | Connecticut | Rhode Island |
|---|---|---|---|
| Construction License | CSL Required | Not Required | Not Required |
| HIC Registration | Required | Required | Required |
| Minimum Liability Insurance | $500,000 | $100,000 | $100,000 |
| Guaranty Fund | Up to $10,000 | Available | Limited |
| Exam Required | Yes (CSL Exam) | No | No |
Massachusetts’s $500,000 liability minimum is five times what Connecticut and Rhode Island require. The CSL examination requirement is also unique among New England states and adds a meaningful layer of competency verification.
