Roofing in Leonia
Why Leonia homeowners
call Pro Gen.
Leonia has a long history as a home for artists and writers, and much of its housing reflects its early twentieth century growth: Victorians, colonials, and foursquares on hilly, tree-lined streets. Overpeck Creek and its park run along the western side of town. Many of these older houses have steep roofs, porches, dormers, and brick chimneys that need careful work.
Victorians, colonials, foursquares, and Tudors from the early twentieth century, plus post-war homes. Mostly asphalt shingle, with some slate.
Every Leonia 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 Leonia roofs
Steep older roofs
Victorians and foursquares often have steep pitches, multiple gables, and dormers that need careful setup and flashing.
Porch roofs
Front porches on older homes often have low-slope roofs that leak where they meet the house.
Canopy and gutters
Mature trees across town keep gutters full and add storm risk.
What we do
Two jobs.
Done properly.
Full replacements and repairs. Both done by our own crews, both photographed from the air.

Leonia questions
Roofing questions from Leonia
How much does a new roof cost in Leonia?
Most full replacements in Leonia 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.
Do I need a permit to replace a roof in Leonia, NJ?
Leonia is a borough, and its construction office issues the permit for roof replacement. We handle the filing and inspections. Pro Gen handles the application, fees, and the final inspection for you.
How long does a roof replacement take in Leonia?
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 Leonia today?
Yes. Emergency leak and tarp calls in Leonia are dispatched the same day. We stop the water first, photograph the cause from the air, then quote the permanent fix.
My Leonia Victorian has a leaky porch roof. Is that a big job?
Usually not. Porch roofs are small, and leaks typically come from worn membrane or flashing at the house wall. We can repair or replace the porch roof without touching the main roof if it is in good shape.
