Both aluminum and steel gutter guards offer unique benefits. Aluminum guards are lightweight, resistant to rust, and typically more cost-effective. They are also available in a variety of colors to match your home’s exterior. On the other hand, steel gutter guards are extremely durable and can withstand heavy debris and harsh weather conditions. However, they may be more expensive and potentially susceptible to rust over time. Your choice between aluminum and steel should depend on your budget, aesthetic preference, and the specific demands of your local climate.
