Roof area — not house area — drives the bill, and pitch inflates it: the same footprint gains surface as the roof steepens. Contractors measure in squares and price $450–$950 per square for asphalt in Mercer, so pinning down the square count is the fastest way to sanity-check a quote.
Architectural asphalt is the Mercer default and the price anchor. Metal roughly 1.8×s the job, cedar about 1.5×, and slate 3.5× or more — but the multiples buy lifespan: metal and slate can outlast two or three asphalt roofs. Match the material to how long you'll own the house.
Steep roofs add 25–50% for staging, harnesses, and slower work; a second shingle layer adds $50–$100 per square of tear-off; and tight urban lots — common around Mercer — add cost for dumpster placement and material handling on three-story homes.
Nobody knows the deck's condition until tear-off. Rotted sheathing runs $70–$120 per sheet to replace, and 5–10% of sheets commonly need it on older roofs. An honest quote states its per-sheet price up front rather than leaving decking as an open-ended extra.
