The answer to 'flashing warranty' is that the warranty on roofing flashing typically lasts 10-20 years, depending on the material and installation quality. Flashing is the metal or rubberized material used to seal around roof penetrations like chimneys, vents, and skylights. A proper flashing installation is critical to preventing leaks and water damage. The warranty period can vary, but most quality flashing materials are designed to last the lifetime of the roof when installed correctly.
Homeowners should review the warranty details provided by the flashing manufacturer and roofing contractor. Proper maintenance, such as regularly inspecting and resealing flashing, is also important to maximize the lifespan. If flashing issues arise within the warranty period, the homeowner may be able to get it repaired or replaced at no additional cost.
