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 that is installed along the edges of a roof to help direct water away from the roof deck and fascia. It is a critical component of a roofing system, as it helps prevent water damage and leaks.
The lifespan of drip edge can vary depending on the quality of the material, the climate, and how well the roof is maintained. Higher-quality metal drip edge, such as aluminum or stainless steel, will generally last longer than lower-quality options like galvanized steel. Drip edge in harsher climates with more exposure to the elements may also have a shorter lifespan than in milder regions. Proper installation and regular inspections and maintenance can help extend the life of drip edge as well.
