The answer to 'how often to replace soffit' is that soffit typically needs to be replaced every 20-30 years, depending on the material and climate. Soffit is the exterior material that covers the underside of a roof's overhang, and it plays an important role in protecting a home's structure from the elements. Over time, soffit can become damaged, worn, or discolored, requiring replacement to maintain the home's curb appeal and prevent water damage.
The lifespan of soffit depends on the material, with vinyl and aluminum soffit lasting longer than wood or fiber cement. Homes in harsher climates with more extreme weather may also need to replace soffit more frequently. Regular maintenance, such as cleaning and inspecting the soffit, can help extend its lifespan. If you notice any cracks, holes, or other signs of wear, it's a good idea to have a professional roofing contractor evaluate the condition of your soffit and recommend replacement if necessary.
