The answer to 'how long does fascia last' is that fascia typically lasts between 20-40 years with proper maintenance. Fascia is the trim board that runs along the roofline of a home, protecting the roof's edge and the interior from moisture damage. The lifespan of fascia can vary depending on the material used, the climate, and how well it is maintained.
Wooden fascia is the most common type and can last 20-30 years with regular painting and caulking to prevent rotting and weathering. Aluminum or vinyl fascia can last 30-40 years or more with minimal maintenance. Proper installation and ensuring adequate ventilation are also key factors in the longevity of fascia boards.
