How much deposit can a roof replacement contractor ask for in Massachusetts?

Massachusetts law caps roof replacement deposits at 33% of the contract. On a typical $21,970 roof replacement, the maximum legal deposit is $7,316. The statute is MA 940 CMR 18.05 (Home Improvement Contractor Act). Any contractor demanding more is in violation of state law — refuse and report to the state contractor licensing board.

Industry standard for roof replacement: 10%. Fast turnaround (1–3 day install). Industry standard: 10% deposit OR zero deposit for insurance work (insurer pays the contractor directly via ACV check). Most legitimate Massachusetts contractors will follow this norm regardless of whether the state has a statutory cap.

Yes — anything above 33% is illegal in Massachusetts under MA 940 CMR 18.05 (Home Improvement Contractor Act). File a complaint with the state contractor licensing board, share the written request, and consider it a permanent red flag against that contractor. Reputable contractors know the law.

Best practice in Massachusetts: 10% deposit at contract signing → milestone-based progress payments tied to inspectable phases (rough-in, mid-build, substantial completion) → 5–10% retention held until punchlist + final inspection sign-off. Never pay materials in full upfront; if your contractor goes under, the materials supplier owns those goods, not you. Pay via check or credit card — never wire transfer to a personal account.
