The repair itself

Researched minimum charges for a roof repair run from $150 to $300, with $225 typical. A small repair, such as replacing a few blown-off shingles or a cracked pipe boot on an easy-to-reach roof, usually sits near $150. Repairs that involve some flashing work or a small area of shingles come in near $225. More involved single repairs, such as rebuilding a section of valley or reflashing a chimney side, push toward $300, and above it when several are combined.

Decking found under the shingles

If water has been getting in, the plywood under the leak may be soft. Each damaged sheet is replaced, with researched prices from $75 to $120 per sheet depending on thickness and how hard it is to reach. A good repair quote says up front that decking will be priced by the sheet if it is found, rather than leaving it as a surprise.

Pitch, height and access

A one-story ranch with a walkable slope is quick to set up on. A steep roof on a three-story house needs roof jacks, harnesses and more time moving around, so the same repair costs more. Repairs that can be reached only from a lower roof or over landscaping also take more setup.
