Foam gutter guards typically last between 3 to 5 years, depending on the climate and the amount of debris they encounter. Over time, foam can degrade due to exposure to sunlight, moisture, and debris, making them a more temporary solution compared to metal or micromesh options.

Foam guards are an affordable option, but they have a shorter lifespan compared to more durable alternatives. In areas with heavy debris or extreme weather, foam may need to be replaced more frequently to maintain effectiveness.
