Roof surface area
The roof itself is usually larger than the square footage you see on the floor plan. A steeper pitch adds surface area and materials.

The three big cost drivers
Good estimates account for the job—not just the house.
Tear-off and disposal
Removing old shingles, hauling debris, and repairing what is found below the old roof can change a written quote.
Labor and access
Height, pitch, job access, local labor, and permit requirements are the parts that make two similar houses price differently.
What to compare in a bid
A lower number is not always a lower-cost roof.
- Is removal of the existing roof included, or assumed?
- What material and warranty level is actually being quoted?
- Does the price include flashing, ventilation, disposal, and permits?
- What could change after the contractor inspects the decking?
