Flat Roof Repair Summit, NJ
A Summit roofer who works on low slope roofs can fix open seams, splits, blisters, failed flashing and clogged drains on EPDM, TPO, PVC, modified bitumen and built-up roofs, once the leak is traced to its real source. Call (908) 679-5768 to reach a local roofer.
Water sits on a flat roof longer than on any other kind of roof, and that is where the trouble starts. Instead of shedding water fast, a low slope roof depends on an unbroken membrane, tight seams and working drains, so one open lap or clogged scupper can send water inside. Most flat roofs are not truly flat, by the way: they are built with a slight slope, ideally about a quarter inch per foot, toward drains, scuppers or gutters.
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. Moisture meters, an infrared scan at dusk or a small core cut show whether the insulation is wet, which changes the repair.
Until the visit, keep safety first. Stay off the roof during or after a storm, keep away from edges and skylights and avoid any soft or spongy areas, which may be a rotted deck. 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.
Many flat roof repair calls in Summit also turn up a need for flat roof replacement or rubber roof repair.

Call nowThe process
What happens during a flat roof repair
The repair has to bond to the existing roof and stop the real leak.
Check the system
Every flat roof type has its own repair method, so the membrane is identified before anything else. Asphalt products, for example, damage rubber membranes.
Find the source
Inspection covers every seam, curb and penetration near the leak, along with drains and scuppers. If the source is unclear, sections are water tested one by one.
Moisture check
Moisture readings or a small core cut show whether the insulation under the leak is wet. Wet insulation is cut out and replaced, because it never dries under a sealed membrane.
Make the repair
The patch matches the roof: primed tape for rubber, hot-air welded membrane for TPO and PVC, and new cap sheet for torch-down. Blisters are opened, flattened and sealed with a patch.
Reseal flashing
Flashing at parapet walls, curbs, skylights and vents is re-adhered or replaced, and termination bars are refastened. Most flat roof leaks start at flashing rather than in the open field.
Clear the drainage
Drains, scuppers and gutters are cleared, drain strainers are replaced and low spots are noted. Persistent ponding points to a slope problem that a patch cannot fix.
What is included

Flat Roof Leak Repair Summit, NJ
Flat roof leak repair is mostly detective work. The real hole is often several feet away from the wet spot, at a seam, curb, drain or edge. That is why patching the spot above the stain so often fails.
A good Summit roofer checks the most common leak points first: seams, wall flashing, curbs around HVAC units, pipe penetrations and 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 Summit, NJ
A low slope roof has some pitch but not enough to shed water as quickly as a standard roof. These roofs are common over porches, sunrooms and additions, and they are covered with many different materials. Shingles below 2 in 12 are not allowed under most codes, and between 2 and 4 in 12 they need a doubled underlayment, so leaks often trace back to the wrong material for the pitch.
Swapping shingles for a membrane on a low porch roof often ends recurring leaks. Smaller repairs on low slope roofs include resealing flashing where the porch meets the house wall and replacing worn roll roofing. Ask the Summit roofer whether the roofing material fits the slope.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Summit, NJ have the roof checked in the fall and again after the snow melts.

Flat Roof Repair FAQ
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. Ask the roofer whether the roof is a good candidate after repairs.
Does standing water damage a flat roof?
Standing water that lingers two days or more harms most flat roofs. Ponding stresses the deck, ages the membrane and turns pinholes into leaks. 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. If moisture readings show wet insulation over large areas, replacement usually makes more sense. A moisture scan helps make that call.
What causes flat roof leaks?
Seams, flashing and drains cause most flat roof leaks. Repeat leaks often mean the real source was never found, or wet insulation was left under the patch. Call (908) 679-5768 to have the roof checked properly.
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.
