The answer to 'lifespan of drip edge' is that the typical lifespan of a properly installed drip edge is 20-30 years. Drip edge is a metal flashing that is installed along the edges of a roof to help direct water away from the roof and prevent damage to the fascia and siding. When installed correctly and maintained, a quality drip edge can last for decades. However, factors like weather, exposure, and the specific materials used can impact the lifespan.
Homeowners should inspect their drip edge periodically and replace it if it becomes damaged, corroded, or loose. Replacing drip edge is a relatively simple DIY project, but it's important to ensure proper installation to maximize its longevity and effectiveness.
