Most gutter guards sold in Troy 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.
Hillside runoff pushes joint sand downhill, and the city's shaded, damp microclimate lets moss establish in walkway joints within a couple of seasons.
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.
