Wet insulation
Wet insulation is cut out and new boards are fitted so the repair is dry underneath.

Flat Roof Repair South Orange, NJ
A roofer in South Orange can repair a flat roof by finding where water gets through the membrane and patching seams, blisters, punctures and flashing with material that matches the roof, and tell you whether the rest of the roof has years left. One call to (973) 858-1859 reaches a nearby flat roof repair pro.
A flat roof has no steep pitch to push water off, so small defects matter more. The whole system relies on the membrane staying sealed and the drains staying clear, which is why a single defect causes so many leaks. They should slope slightly, roughly a quarter inch per foot, and where they do not, water ponds.
The stain inside is almost never directly under the hole. Moisture travels sideways through insulation and along the deck, so the inspection covers the whole area around the stain. A moisture meter or infrared scan shows how far wet insulation spreads.
Until the visit, keep safety first. A flat roof feels safe but is not: edges have no rail, skylights will not hold a person and wet decks can be weak. Inside, catch drips in a bucket, and if the ceiling sags with water, a small hole away from light fixtures lets it drain into the bucket before it collapses.
If the problem goes deeper than it first looked, a South Orange roofer may also recommend flat roof replacement or rubber roof repair.

Call nowThe process
The flat roof repair process
The repair has to bond to the existing roof and stop the real leak.
Know the membrane
First comes knowing what the roof is made of, since EPDM, TPO, PVC and asphalt roofs need different patch materials. Using the wrong material can make the leak worse.
Trace the leak
Likely entry points are checked first: seams, flashing, penetrations, drains and edge metal. Testing small areas with a hose narrows down the entry point.
Test for wet insulation
A moisture meter, infrared scan or core sample shows how far water has spread. Wet insulation is cut out and replaced, because it never dries under a sealed membrane.
Make the repair
EPDM is cleaned, primed and patched with seam tape, TPO and PVC get a heat-welded patch, and modified bitumen gets a torched or self-adhered patch. Cracked areas are cleaned and covered with new membrane.
Reseal flashing
Flashing at parapet walls, curbs, skylights and vents is re-adhered or replaced, and termination bars are refastened. Edges and penetrations are where most flat roofs fail first.
Drainage
The roofer cleans drains and scuppers and checks that water reaches them. Low areas that hold water may need added slope later.
What is included
Common flat roof repairs
Scupper repair
Clogged drains are cleaned and their flashing checked so water leaves the roof.
Puncture repair
Damaged spots are covered with new membrane before water spreads into the insulation.
Flashing repair
Loose wall and unit flashing is renewed since most leaks start there.
Seam repair
Lifted laps are re-adhered, taped or welded using the method that suits the roof type.

Flat Roof Leak Repair South Orange, NJ
A flat roof leak rarely sits right above the stain inside. Once water gets under the membrane, it spreads sideways and can drip far from the entry point. That is why patching the spot above the stain so often fails.
Seams and flashing are the usual suspects on a South Orange flat roof, along with clogged drains. Once the source is found, the repair uses matching material and the wet insulation beneath it is replaced. Skipping the insulation means the leak seems to keep going.

Low Slope Roof Repair South Orange, NJ
Low slope roofs sit between flat and steep, with a pitch of about 2 to 4 inches per foot. You will find shingles, roll roofing and membranes on low slope roofs. Shingles are allowed on low slopes only with special underlayment, and on flatter pitches they leak.
When the material does not suit the slope, the lasting fix is often to switch that section to a membrane such as modified bitumen, EPDM or TPO. Typical fixes are flashing at the house wall, seams in rolled roofing and damaged edges. For a South Orange porch or addition, ask if the material matches the pitch.

How the weather here affects roofs around South Orange
Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in South Orange, NJ have the roof checked in the fall and again after the snow melts.

Flat Roof Repair FAQ
Why does my flat roof keep leaking?
The most common causes are open seams, failed flashing, punctures, blisters and clogged drains. Repeat leaks often mean the real source was never found, or wet insulation was left under the patch. Finding the entry point and drying out the layers stops the repeat.
Does standing water damage a flat roof?
Lingering water speeds up wear on a flat roof. It wears the surface, adds load and makes any opening leak. Drain cleaning, crickets or tapered insulation solve ponding.
Can a flat roof be repaired instead of replaced?
A repair makes sense when the membrane is sound and the damage is local. Widespread seam failure, cracking or wet insulation across the roof points toward replacement. A moisture scan helps make that call.
Can I just coat my flat roof to stop a leak?
Coating over a leak without fixing it first rarely works. Seams, flashing and punctures need proper repair, and wet insulation has to be replaced before any coating goes on. A coating may make sense after the leak is fixed.
How do I know what type of flat roof I have?
Each flat roof type looks a little different. Rubbery black is EPDM, white plastic sheets are TPO or PVC and gravel over asphalt is built-up. Confirming the type is the first step in any repair.
