Last year I bought a house that had the stainless steel micro model installed. The house was surrounded by 80’ tall Maples & Birch. TONS OF LEAVES.Yes, it the micro mesh keeps all leaf and seeds out of the gutter 100%. What the manf and dealers won’t tell you is that you must clean the mesh 2x’s a year to get spring pollen, mold, & fall leaf dust off. Otherwise it will eventually keep EVERYTHING out, including WATER. Major ice problems flowing over the gutters. No it was not the result of ice damming. I removed it all & just deal with the leaves 3x’s each fall.Got ranch home with easy access to the gutters - get the micro mesh. Easier to clean that than clean gunk out of the gutter.hire a young buck to climb a ladder. A whole lot cheaper.
