Roofing in Rocky Hill
Why Rocky Hill homeowners
call Pro Gen.
Rocky Hill is a tiny borough along the Millstone River and the Delaware and Raritan Canal, and much of it is within a historic district. Many homes date to the 1800s and early 1900s, with steep roofs, porches, and old chimneys. Roofing here needs a careful approach to old decking and attention to how the house looks from the street.
19th and early 20th century homes with steep gable roofs, porches, and chimneys, plus some later houses on the edges of the borough.
Every Rocky Hill 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.

What we check on Rocky Hill roofs
Historic district approval
Certain exterior work in the historic district needs approval before it starts. Choose materials with that review in mind.
Old chimneys and flashing
Old chimneys often have worn flashing and mortar. Re-flashing during a re-roof prevents leaks.
Porch roofs
Low-pitch porch roofs on older homes often need a membrane instead of shingles to stay watertight.
What we do
Two jobs.
Done properly.
Full replacements and repairs. Both done by our own crews, both photographed from the air.

Do I need a permit to replace a roof in Rocky Hill, NJ?

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.
Can you fix a leak in Rocky Hill today?
Yes. Emergency leak and tarp calls in Rocky Hill are dispatched the same day. We stop the water first, photograph the cause from the air, then quote the permanent fix.
Does my Rocky Hill home need approval before a roof replacement?
If it is in the historic district, certain exterior work requires approval through the Planning Board before it starts. Check with the borough first. We can supply shingle samples and specifications for your application.
