01Drone Inspection
We fly the roof before quoting. You see every slope, valley and flashing on the estimate.

Full roof replacements, leak repairs, flat roofs and chimney flashing for Ho-Ho-Kus homeowners. Our own crews, GAF-certified installation, and a drone inspection on every Ho-Ho-Kus job, free with your estimate.



North NJ's most populous county. High demand for architectural shingle replacements and emergency leak repairs in historic and luxury homes. In Ho-Ho-Kus that usually means architectural shingle replacements on older homes, chimney and skylight flashing repairs, and the occasional flat-roof coating on additions and garages.
Every Ho-Ho-Kus estimate starts with a drone flight. You get the photos whether or not you hire us, so you know exactly what's up there before you spend a dollar.
