1 · Product approvals

Product approvals

Massachusetts has no state roofing product approval system. The residential code requires roof coverings to follow the manufacturer's printed instructions or code evaluation report, which govern where they conflict with the code section.

Where the code conflicts with the manufacturer's printed instructions or a code evaluation report, those instructions or the report govern.Code evaluation reports (ICC-ES, UL, IAPMO): 48 roofing reports

2 · Permit forms

City re-roof permits

Massachusetts uses one statewide building code that cities enforce. Re-roofing is not on the residential permit-exempt list, and the state's HIC chart says roofing, new or replacement, needs a building permit, a CSL and HIC registration. Permit applications must include the HIC registration number.
