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 West Caldwell homeowners. Our own crews, GAF-certified installation, and a drone inspection on every West Caldwell job, free with your estimate.



West Caldwell is a mostly residential township just west of Caldwell, and our office is only minutes away. Most homes were built in the 1940s through the 1960s, so Cape Cods, ranches, split-levels, and Colonials make up much of the housing, with some larger newer homes. Many of these roofs are on their second or third replacement, and upgrading ventilation and underlayment is often as important as the shingles themselves.
Postwar Cape Cods, ranches, split-levels, and Colonials with simple gable and hip roofs in asphalt shingle, plus some commercial buildings with flat roofs.
Every West Caldwell 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.

Chimney reflash
Skylight
Flat roof coatingHomes from the 1950s and 1960s often have minimal attic venting, which shortens shingle life and promotes winter ice dams.
Dormer valleys and side walls on Cape Cods are common leak points as flashing ages.
Mature yard trees fill gutters each fall, backing water up under the roof edge.
Full replacements and repairs. Both done by our own crews, both photographed from the air.

05GAF architectural shingles, ridge vent, cleanup, then a final drone pass you get to keep.
Most residential replacements are torn off, dried-in and shingled within one to two days.
Most full replacements in West Caldwell land between $7,500 and $22,000 depending on roof size, pitch, layers to remove, and the shingle you choose. Repairs usually run $350 to $1,850. The drone inspection gives you an exact number, free.
West Caldwell is a township, and its construction office issues roofing permits. We file the application and schedule the inspection. Pro Gen handles the application, fees, and the final inspection for you.
Most homes are torn off, dried-in and shingled in one to two days. Larger or more complex roofs can run a third day. Your roof is never left open overnight.
Yes. Emergency leak and tarp calls in West Caldwell are dispatched the same day. We stop the water first, photograph the cause from the air, then quote the permanent fix.
A new roof with ice and water shield at the eaves helps, but ice dams usually come from heat escaping into the attic. Adding ventilation and fixing insulation gaps during the replacement addresses the cause. We look at both when we inspect.
