Yes, but only if you choose the right type. Many basic systems let pine needles and small debris through, which defeats the entire purpose of having protection in the first place.We install micro-mesh systems with openings small enough to block pine needles, maple seeds, and even shingle grit while still allowing water to flow freely. The mesh is fine enough to catch debris that would normally slip through larger openings.For Commack homes with pine trees or other needle-dropping trees, we specifically recommend stainless steel micro-mesh guards. They’re the most effective solution for keeping gutters completely debris-free year-round.
