Before you start, here is the math. Your living space is divided by the number of stories to estimate the home's footprint. Next comes the slope factor (1.12 walkable, 1.30 steep) and a 1.10 overhang allowance; the result is the roof's surface in square feet. Roof area times a per-square-foot rate for your material gives the range.
The rates come from the cost rows in our roof replacement cost guide. Shingles run from about $4.59 per sq ft (Missouri asphalt, This Old House, 2026) to $8.00, the top of HomeBlue's 2024 St. Louis-area range, which covers architectural and Class 4 shingles. Metal uses HomeBlue's St. Louis-area range of $8 to $13, and This Old House's 2026 Missouri metal average of about $8.51 falls inside it. HomeBlue's figures come from a cost model, not local bids.
