Flat roof repair in Bernardsville NJ usually starts with water that should have run off and did not. This is an old Somerset Hills borough, full of large estate-era homes with rear additions, sunroom roofs, and porch decks that went flat decades ago. Those sections hold water.
We work on the membrane systems they are built from, and we cover Bernardsville on a regular service run out of our Clifton base.
We Find the Real Source
The wet spot inside is rarely under the failure. We trace it to the open seam or the bad flashing before anyone seals a thing.
Worth the Drive
We serve Bernardsville from our Clifton base. We schedule it as a planned run, so you get a set date.
A Number in Writing
You get an itemized figure after the free inspection.
Who Signs Off on the Work in Bernardsville
The Bernardsville building department issues the borough's permits, and its inspector does the sign-off. A seam patch or a drain re-flash on an addition is the kind of ordinary repair that usually needs none. For membrane replacement or deck work, confirm the requirements with the department.
We are registered with the New Jersey Division of Consumer Affairs as a home improvement contractor, NJ HIC #13VH11720500. You can check that on the state licence verification portal before you hire us, or anyone else. We install GAF and Owens Corning roofing systems and are not enrolled in either manufacturer's contractor certification program.

Why Bernardsville Has More Flat Roof Than It Looks
Drive the streets up in the Mountain Colony and you see steep, complicated rooflines in Tudor Revival and Colonial Revival styles, with large slate and shingle fields. The flat roofs sit behind them, on rear additions, enclosed sleeping porches, kitchen bump-outs and the connectors between a main house and a converted carriage house. Most of those low-slope sections are flat roof membrane rather than shingle.
In the Somerset Hills, every renovation that pushes the footprint out tends to add another flat or near-flat section. The joint where it meets the original pitched roof is where leaks start. We repair both systems, so one company handles that transition.

Warning Signs on a Low-Slope Roof
Early signs of a failing flat roof include water still standing two days after a storm, seams lifting at the edges or curling into fishmouths, soft or spongy spots underfoot, a ceiling stain under a dead-flat section, and old coating that keeps peeling. Any one of those is worth a look, and two together call for a prompt inspection.
Flat Roofing Is Its Own Trade
A pitched roof drains by slope, while a flat roof depends on its seams, flashing and drains. A tar job over an EPDM seam tends to last one summer before the first hard freeze opens it again. Bernardsville roofs deal with cold winters and nor'easters, so the membrane has to be detailed for that.
Membranes We Work With
EPDM rubber is the black membrane on most residential flat roofs out here. It lasts for decades when the seams and flashings are kept up. When EPDM does fail, the seams are usually the problem.
TPO repairs have to be welded, never glued, because a glue patch on TPO will leak.
Modified bitumen, the torch-down rolls, shows up on plenty of older Bernardsville additions. Blisters and open laps get cut out and patched with the same material.
What Wears Out a Flat Roof Up Here
Ponding water is the big one. Anything still sitting forty-eight hours after rain is shortening the roof's life. Sometimes the real fix is drainage.
Backed-up drains and scuppers come from the heavy tree canopy in this part of Somerset County. Clogged drains leave water standing on the roof.
Freeze-thaw opens a hairline gap in a seam over a winter of cold nights. Foot traffic also punctures membranes.
The Pitched-to-Flat Transition
This is the first joint we check on a Bernardsville addition. A steep main roof sheds onto a flat addition off the back, and when the original flashing at that joint fails, water runs behind it and into the wall.
We rebuild that transition with counter-flashing into the pitched roof, a membrane that turns up the wall far enough, and a kick that sends water out onto the flat field where the drains can take it.
Patch, Coat, or Re-Cover: The Math
A seam repair suits a sound EPDM or TPO membrane. A silicone or acrylic coating suits a worn but dry roof. A re-cover suits a membrane that has gone brittle across the whole field.
Replacement is for a roof that is wet underneath, because covering trapped moisture keeps the water in. The free inspection tells us which roof you have, and on a tricky one a moisture scan settles the question.
Winter repairs are possible: some products need warmth to cure, so a cold-weather call gets a temporary seal and a finish pass once it warms up.
Estates, Carriage Houses, and Small Commercial
Not every flat roof out here sits on a single-family house. The borough has its share of converted carriage houses, pool houses, and the flat roofs over connectors between buildings on the larger properties around the Cross Estate and the Olcott Avenue side of town.
Down by the historic downtown and the Bernardsville train station there are mixed-use buildings with membrane roofs carrying HVAC units, and those curbs are the first place to check for a leak. Every penetration a tenant adds is another seam to watch.
For owners with more than one building, we can put the roofs on a twice-a-year check, with drains cleared, seams walked and photos filed, and several buildings can share one schedule.
We run flat roof jobs to Bernardsville and the nearby Somerset Hills towns, from a one-story pool house to a large estate.
What Sets the Number on a Flat Roof
System type drives a lot of it.
EPDM, TPO, and modified bitumen each repair differently. Then it comes down to how much ponding the roof carries, how far the water reached into the deck, and how many seams and flashings have to come apart. A single failed seam is an economical fix.
Widespread membrane failure means a re-cover or replacement, and we talk that through with photos in hand.
A Warranty and a Phone Line
Roof repairs carry a 2-year warranty, and roof replacements carry a 50-year warranty. We are licensed and insured, and the same roofers who walk your membrane and write the number also weld the patch. Seniors and military get a $500 discount, and 0% financing is available.
