The answer to 'how long does drip edge last' is that drip edge typically lasts between 20-30 years when properly installed and maintained. Drip edge is a metal flashing installed along the edges of a roof to help direct water runoff and prevent water damage to the roof and home. It is a critical component of a roof system that helps protect the home's exterior from water intrusion.
The lifespan of drip edge can vary depending on the material used, the quality of the installation, and the environmental conditions the roof is exposed to. Aluminum and galvanized steel drip edge tend to last the longest, while cheaper materials like vinyl may only last 10-15 years. Proper installation by a professional roofer and regular inspections/maintenance are key to maximizing the lifespan of drip edge.
