The answer to 'how often to replace fascia' is that fascia boards typically need to be replaced every 15-20 years, depending on the material and local climate conditions. Fascia is the horizontal board that runs along the lower edge of a roof, providing an important structural and aesthetic function. Over time, fascia can become worn, cracked, or damaged due to exposure to the elements, which can lead to leaks, water damage, and other issues if not addressed.
Regularly inspecting the fascia and making any necessary repairs or replacements is an important part of maintaining the overall health and longevity of your roof. If the fascia is in good condition, it may not need to be replaced for several decades. However, if it is showing signs of significant wear or damage, it's generally best to replace it sooner rather than later to prevent more serious problems from developing.
