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

Montana has no statutory cap on contractor deposits. No specific statutory cap on residential renovation deposits. For roof replacement, industry standard is 10% — meaning on a $17,745 project, expect $1,775 max. Any request above $2,662 is a red flag.

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 Montana contractors will follow this norm regardless of whether the state has a statutory cap.

Montana doesn't have a statutory cap, but industry-standard deposits sit between 10–25% for most roof replacement projects. A request above 15% is a strong signal of cash-flow problems (the contractor is funding earlier jobs with your money) or outright fraud risk. Get 2 more written quotes before signing anything.

Best practice in Montana: 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.
