Compare the systems
Leaf Exterminator, Hydro Flo, Shur Flo or Pro Flo: how the four guards compare.
All four sit on or in the gutter and let water through while debris stays on top. The differences are the filter (micro‑pore, stainless mesh or perforated aluminum), how each one mounts, and the manufacturer’s warranty. Here are the specs as each maker lists them.
