Most gutter guards sold in Schenectady fail the same way. Hardware-store screens sag and trap debris on top, and micro-mesh eventually blinds over with shingle grit and pollen until water sheets straight over the front.
Older Schenectady installs were often laid on thin bases with plain masonry sand, so joints wash out fast and edges start to creep after a decade of freeze-thaw.
We install RainDrop® Pro Gutter Guard: a UV-stabilized polypropylene system that retrofits 5" and 6" gutters, handles high-volume roof valleys without overshoot, and sheds ice instead of holding it. Every install starts with a full cleanout and ends with a water flow test.
