Roof Replacement Cost per Square Foot
Understand roof replacement pricing by roof area, pitch, tear-off layers, shingle grade, access and decking condition.
Estimate roof costUse roof area, not home floor area
The roof surface is usually larger than the building footprint because of pitch, overhangs and attached sections.
What changes the installed rate
Roof geometry and jobsite conditions affect labor as much as shingle selection.
- Pitch, height and access
- Number of existing layers
- Valleys, dormers, skylights and chimneys
- Underlayment, flashing and ventilation scope
- Decking repair and disposal requirements
Compare complete scopes
A low rate may exclude tear-off, damaged decking, flashing, permits or disposal. Compare line items rather than the headline total alone.
