Roof Replacement — Massachusetts license requirements
01 The project
The starting point is the work itself — Roof Replacement in Massachusetts. The job determines which trades are involved, and the trades determine which license classifications may be required.

02 Jurisdiction
This project is evaluated for Massachusetts — the volume-threshold state. There is no project-value general-contractor licence: the individual Construction Supervisors License (OPSI/BBRS, 780 CMR) turns on building type and the 35,000-cubic-foot test (a registered design professional controls larger buildings), the HIC registration (c. 142A) governs the home-improvement contract on existing owner-occupied 1–4 unit property, and the trades are licensed individually (248 CMR plumbing/gas, 237 CMR electrical). Massachusetts jurisdiction page.
Local building and permit fees were not read — LOCAL_AUTHORITY_REQUIRED — and the CSL initial licensure fee is unpublished (NOT_VERIFIED). Massachusetts imposes no surety bond and no state general-liability minimum on these credentials (verified absences; the Guaranty Fund is the consumer instrument), but every employer needs workers' compensation. State requirements are not the complete story for any city or town.
03 Trade → license
Relations below are recorded per state — only this jurisdiction's classifications are shown.
Trades involved: Roofing.
- May require CSL-SPEC-ROOF — Specialty CSL — Roof Covering confirmed S-MA-HIC-RES rule MA-BUILDING-PERMITChart verbatim: 'Roofing, new or replacement | CSL yes | HIC yes | permit yes — Roofing CSL minimum.' The roof-covering class may not supervise structural roof elements including sheathing (SCOPE-MA-CSL-ROOF-COVERING); minor repairs keep the CSL column at 'yes' with the permit column 'maybe' (permit needed unless the building official calls it an ordinary repair).
- Alternative path CSL-UNRESTRICTED — Construction Supervisor License — Unrestricted confirmed S-MA-CSL-WHEN rule MA-CSL-REQUIREDALTERNATIVE — an unrestricted (or restricted/one-and-two-family) CSL also satisfies the supervision requirement where the work reaches structural roof elements: 1-/2-family dwellings of any size need 'a licensed construction supervisor or a registered design professional'.
- May require HIC-REGISTRATION — Home Improvement Contractor Registration (HIC) confirmed S-MA-HIC-RES rule MA-HIC-REGISTRATIONChart verbatim: 'Roofing, new or replacement | … | HIC yes' — the contractor who signs the homeowner's contract must hold the HIC registration (existing, owner-occupied 1–4 unit property).

06 Rule: MA-BUILDING-PERMIT
The official 'What work requires an HIC, CSL, or building permit?' chart (mass.gov) decides job-by-job — including the numeric local triggers: a fence under seven feet needs no permit or CSL; masonry or exterior retaining walls over four feet need permit + CSL; a shed needs permit + CSL above 200 sq ft of floor area on 1–2 family lots (120 sq ft for others); roofing new/replacement, insulation, demolition, siding, windows and solid-fuel appliances are permit + CSL + HIC. 'For general guidance only … always consult with the appropriate building official.'

Above 35,000 cu ft the RDP controls and no CSL is required (MA-CSL-VOLUME).

09 What decides a Massachusetts re-roof
| Question | Massachusetts answer | Source |
|---|---|---|
| Chart decision | CSL yes | HIC yes | permit yes — 'Roofing CSL minimum' (rule MA-BUILDING-PERMIT) | S-MA-HIC-RES |
| Minor roof repairs | permit column maybe — 'unless considered an ordinary repair by the building official' | S-MA-HIC-RES |
| Scope of the roof-covering class | may not supervise structural roof elements, including sheathing — a restricted/unrestricted CSL takes that | S-MA-CSL-WHEN |
| Who signs the contract | must hold the HIC registration (c. 142A §9) | S-MA-HIC-REG |
Note: the official HIC/CSL/permit chart (19 job types with CSL / HIC / permit columns) and the 35,000-cubic-foot threshold (Above 35,000 cubic feet the registered design professional controls and no CSL is required) are stated in full on the Massachusetts jurisdiction page.
