Budget drivers
What moves the final price.
Tear-off and disposal
Existing layers, weight, access, and disposal requirements affect labor and hauling.
Decking condition
Soft or damaged sheathing is often priced as a per-sheet allowance until the roof is opened.
Roof geometry
Steep slopes, valleys, dormers, chimneys, and multiple levels increase setup and detail work.
Roofing system
Shingle line, underlayment, ice protection, ventilation, flashing, and warranty level should be named.
Permit planning
A checklist before work begins.
- Confirm whether a roofing permit is required for the exact scope.
- Ask whether tear-off, decking, and final inspections are required.
- Confirm contractor registration or licensing documentation the municipality expects.
- Ask who schedules inspections and how approved work is documented.
- Keep product approvals, contract, change orders, and inspection records together.
Better bids
Questions for every contractor.
- How many existing layers are included in the tear-off price?
- What is the unit price for decking replacement?
- Which shingle, underlayment, ice barrier, flashing, and ventilation products are specified?
- How will attic ventilation be evaluated and corrected?
- What workmanship and manufacturer warranties apply, and who registers them?
- How will landscaping, gutters, siding, and the driveway be protected?
