The streets off Roanoke Avenue make a grid of front lawns, short driveways and sidewalks that see plenty of foot traffic. Signature Services LLC covers them the whole year: mowing, edging, trimming, mulch and cleanups while things are growing, then plowing, shoveling and ice control once they stop. In a neighborhood that close-packed, a cleared sidewalk is a favor to the entire block, and an even cut line is the difference between tidy and merely mowed. The switch from one list to the other usually happens inside a single week. Riverhead and the surrounding hamlets stay on the route in both directions of the year.
