The answer to 'lifespan of drip edge' is that a properly installed and maintained drip edge can last 20-30 years or more. Drip edge is a vital roofing component that helps direct water away from the roof edge and fascia, preventing water damage and rot. It is typically made of aluminum, galvanized steel, or vinyl and is installed along the roof's edge during the roofing process.
With proper installation and regular inspection/maintenance, drip edge can provide decades of reliable service. However, factors like weather, climate, and damage can impact its lifespan. In coastal or high-moisture areas, drip edge may need to be replaced sooner due to corrosion. Homeowners should visually inspect the drip edge periodically and have any damage or deterioration repaired promptly by a professional roofer to ensure it continues to protect the roof edge effectively.
