What drives the cost of a roof repair

Dollar figures in this section are US national figures in US dollars.

  1. Roofing material

    Slate and metal need specialized labor; average repairs run from about $400 (flat, foam or single-ply) to $1,800 (slate).

  2. Roof size

    Larger roofs mean more material and time for the same kind of repair.

  3. Size of the damaged area

    A few missing shingles cost far less than a section of decking.

  4. Severity of the damage

    Leaks that have reached decking or framing need more than surface work.

  5. Access

    Steep or high roofs need more safety equipment and time.
