The answer to 'lifespan of flashing repair' is that a properly installed and maintained flashing repair can last 10-15 years on average. Flashing is the thin metal or plastic material used around roof penetrations, edges, and transitions to prevent water leaks. When flashing is repaired correctly using the right materials, it can provide a long-lasting, waterproof seal that protects your roof.
The lifespan of a flashing repair depends on factors like the quality of the installation, the type of flashing used, exposure to the elements, and proper maintenance. With regular inspections and prompt repairs when needed, a flashing repair can continue to function well for many years. However, over time, even the best flashing repair will eventually need to be replaced as the materials degrade.
