Roofing
Roof Replacement Cost by Material and Roof Size
Estimate tear-off, underlayment, flashing, labour and regional factors for a new roof.
Roof area, pitch, layers, access and flashing details can matter as much as the selected shingle or panel.
Key takeaways
- Price the roof surface, not floor area.
- Compare complete assemblies and warranties.
- Insurance is not a maintenance plan.
Measure the right area
Roofing is priced from roof surface area, not living area. Pitch, overhangs, attached garages and complex intersections increase measured area. Contractors often quote in squares, where one square equals 100 square feet of roof surface.
Material and assembly
Asphalt shingles are common and comparatively economical; metal, tile and slate can cost substantially more and may require structural or specialty installation. Compare the full assembly: underlayment, ice-and-water protection, ventilation, flashing, fasteners and manufacturer-compatible components.
What a complete quote includes
Confirm tear-off layers, deck replacement unit prices, disposal, permits, flashing, vents, warranty registration and cleanup. Ask how rotten decking will be documented and approved. Verify contractor liability and workers' compensation coverage.
Insurance and storms
Home insurance generally addresses covered sudden damage, not ordinary wear or deferred maintenance. Do not assume a policy will fund replacement because a roof is old. After a storm, document damage, prevent further loss safely and contact the insurer before authorizing major work.
