Roof Leak Water Damage Cost Calculator
Roof leaks damage attics, insulation, ceilings and walls, and often go unnoticed until staining appears. This calculator estimates the interior water-damage repair from a roof leak — the roof repair itself is separate — based on affected area and materials, adjusted for your region.

Professional roof leak water damage typically costs $400 – $3,000, averaging about $1,200 for a 200 sq ft single-family home with category 1 — clean water. That works out to roughly $4.00–$10.00 per square foot, with most projects completing in 3–8 days. This type of loss is often covered by a standard homeowners policy — typically around 85% after your deductible.

How this calculator works
Unlike simple square-foot estimators, this calculator builds your total from individual cost components — inspection, water extraction, structural drying, equipment rental, demolition, material replacement, cleaning and skilled labor. Each component is priced from a researched 2026 national baseline, then adjusted by your state's cost index and labor market, the water category, and whether emergency service or mold remediation is required.
What affects your cost the most
- Affected area & rooms: more square footage means more extraction, drying and materials.
- Water category: gray and black water require far more sanitizing and disposal.
- Materials involved: replacing hardwood, cabinets or subfloor costs far more than drying drywall.
- Regional labor rates: skilled restoration labor varies by more than 50% across states.
- Emergency service: after-hours dispatch adds a labor premium.
- Mold remediation: containment and treatment add significant cost when present.
Labor costs
Professional restoration labor runs about $55/hour at the national baseline, before regional adjustment. Typical crews of two work through extraction, tear-out, drying setup and cleaning, with reconstruction billed separately when rebuilding is required.
