Use this roof sheathing replacement cost calculator to estimate a planning range for replacing roof decking or damaged roof sheathing. It combines sheet count, material choice, roof complexity, tear-off condition, access, hidden damage risk, and restoration allowances.
This is not a roofing bid. Roof sheathing replacement costs can change after shingles are removed and soft decking, rot, leaks, bad flashing, mold, framing damage, or ventilation problems are visible.
Estimate your roof sheathing replacement cost
How this estimate works
The calculator estimates the sheathing area, adds roof waste, converts the area into sheets, adds material cost, labor allowance, tear-off coordination, hidden damage risk, restoration, access, and regional cost adjustment.
Why roof sheathing replacement changes after tear-off
Soft decking, rot, mold staining, bad flashing, old leaks, delaminated panels, and damaged edges may not be visible until the roof covering is removed.
