The answer to 'lifespan of soffit' is that the typical lifespan of soffit materials is 20-40 years, depending on the material and local climate conditions. Soffit, the underside of the roof overhang, plays an important role in protecting a home's exterior and ventilating the attic space. Properly installed and maintained soffit can last for decades, but factors like weather exposure, moisture, and pests can impact its longevity.
Aluminum and vinyl soffit tend to have the longest lifespan, often lasting 30-40 years with minimal maintenance. Wood and fiber cement soffit have a slightly shorter lifespan of 20-30 years, requiring more regular inspection and upkeep to prevent rot, warping, or damage. Proper ventilation, regular cleaning, and prompt repair of any soffit issues are key to maximizing its useful life.
