What a roof replacement actually costs

Installed cost per square by material, what moves the number, and a worked takeoff.

What is a roof square?

The trade's only unit: 100 square feet, and how squares become bundles and dollars.

6 min

Roofing labor cost per square

How crews pace the work, and what pitch, storey height and tear-off do to the labour line.

Hip vs gable roof

Same squares, different takeoff: waste, ridge cap, eaves vs rakes, wind and venting on one 40 × 30 footprint.
