Fixing a leak in a metal roof typically costs between $300 to $1,500, with most homeowners paying around $650 for a standard repair. The exact cost depends on the leak location, extent of damage, accessibility, and whether structural repairs are needed.
Metal Roof Leak Repair Cost Breakdown
- Minor leak at seam or fastener - $200-$500 (sealant and flashing repair)
- Panel replacement - $400-$1,000 (removing and replacing damaged panels)
- Flashing repair or replacement - $300-$800 (around chimneys, vents, or valleys)

- Structural damage repair - $1,000-$3,000+ (if decking or rafters are affected)
Common Causes of Metal Roof Leaks
- Loose or corroded fasteners - Screws can work loose or rust over time
- Failed sealant - Caulking around penetrations deteriorates
- Damaged flashing - Metal flashing can separate or corrode
- Panel seam separation - Thermal expansion can cause seams to open
- Penetration points - Skylights, vents, or chimneys are common leak sources
Metal roof leaks should be addressed quickly, as water infiltration can damage underlayment and roof decking. Early repairs are typically less expensive than waiting until structural damage occurs. Always hire a roofer experienced with metal roofing systems.
