We tested gutter screens on one of our properties a while back they definitely helped reduce large debris, but we still found that fine buildup and shingle grit can clog things up over time. Even with screens installed, we had to stay on top of routine Gutter Cleaning to keep water flowing properly and prevent overflow issues.
The free sample sounds like a good way to see if the product fits your setup, but I’d still recommend pairing any screen system with regular professional cleanings for best long-term results.
