National Baseline & Scope Drivers
Tearing off and replacing a residential roof, including underlayment, flashing and disposal. National planning range for this job sits between $8,000 and $45,000.
Key Price Drivers for Roof Replacement
- Material: Architectural asphalt shingle is the baseline. Standing-seam metal runs two to three times more, and tile or slate higher still, with structural implications.
- Roof area and pitch: Roofing is priced per square, meaning 100 square feet. Steep pitches above 6:12 require staging and fall protection that add 20 to 50% to labor.
- Layers to tear off: Each existing layer adds labor and disposal cost. Two or more layers must come off; a single layer sometimes may be roofed over, though it is rarely a good idea.
- Decking condition: Rotten sheathing is not visible until tear-off. Contracts should state a per-sheet replacement price so the change order is not a negotiation on the day.
- Complexity: Valleys, dormers, chimneys, skylights and multiple planes all add flashing detail, which is where roofs leak and where skilled labor is spent.
