Video — Gutter Helmet is terrible for your roof, especially with needles
Gutter Helmet aka Harry Helmet aka Gutter Topper installs between the 1st and 2nd course of shingles, causing a “leveling off” of the slope of the roof. This pitch change creates a dead spot where water collects and pools ON the roof, resulting in that water soaking through the shingles thereby rotting the roof deck over time. This creates exactly the problem it is sold to prevent: water damage. There is no point in spending your hard earned money on something that just creates a worse problem than clogged gutters.
