High-quality gutter guards, such as those made from stainless steel or aluminum, can last 20 years or more with proper maintenance. Foam or plastic guards typically have a shorter lifespan, lasting around 5–10 years, depending on weather conditions and debris levels.

The lifespan of gutter guards depends on the material. Metal and micromesh guards last longer than foam or plastic options, but regular maintenance is key to ensuring that all types of guards function effectively over time.
