THE MATH

Roof repair cost formula

Total = max($500, area × rate × layers) + disposal

A small leak repair runs about $4/sq ft, a section about $5.50 and a partial re-roof about $6.50, materials and labor included. Two layers add 25%. Debris disposal is ~$180.

PRACTICAL EXAMPLE

100 sq ft, small leak repair, one layer

The $500 job minimum applies. Disposal = $180. Total ≈ $680.
