As a Dunmore commercial roof repair contractor, we trace warehouse leaks across the roof and set each repair edge where the insulation is dry again.
Dunmore commercial roof repair on warehouses starts by finding how far water spread, because a stain inside rarely matches the wet area above.
Big low-slope roofs on storage and distribution buildings let water run along the deck and soak sideways through insulation before it drips. The stain you see marks the lowest point, which can sit yards from the opening.
We trace the source, core the roof between the stain and the entry, and draw the repair boundary where boards are dry and firm.
Warehouse roofs in Dunmore leak in a handful of repeat patterns.
A brown ring on ceiling tiles over racking, far from any drain or curb.
Water entered upslope and traveled along the deck. The entry gets found on the roof before any patch is placed.
Soft, spongy spots underfoot in the middle of an open membrane field.
Insulation below has taken on water. Cores show how wide it reaches so the repair covers all of it.
Curled lap edges in long runs of membrane between drains.
Freeze and thaw pry loose laps open across wide roofs. New cover strips tie into firm membrane on both sides.
Scuffed and punctured roofing between the hatch and the units.
Service trips cut into the membrane over time. Patches and walkway pads protect the busiest routes.
Warehouse repairs succeed when they stop at dry roofing. These four failures show why.
A patch cut to the size of the ceiling stain leaves wet boards around it feeding new leaks.
Cores set the true wet edge, and the repair extends to dry, firm insulation.
The entry sits uphill of the stain, so patching above the drip misses it.
Tracing finds the opening on the roof, and it gets repaired first.
Soaked boards keep dripping for days after the opening is closed.
Wet boards come out and new insulation goes in before the membrane is sealed.
Long seams on wide roofs open first where water runs to the drains.
Laps are cleaned, primed, and covered with new strips along the drainage path.
The size of the wet area decides which repair fits.
Repairs end where cores show dry insulation, even when that edge sits beyond the stain seen inside.
Small wet areas get the soaked boards replaced and a new membrane piece welded over them.
Seams and flashing along the path water takes to each drain get repaired together.
When a whole bay is wet, that section is rebuilt to the deck while the rest stays in service.
Mark the edge of the stain and the date, then call. That tells us how fast water is moving inside the roof.
Warehouse repairs add mapping and coring before any membrane comes off.
Each stain and drip location inside gets matched to a grid on the roof above.
Seams, drains, and curbs uphill of every stain are checked for the opening.
Samples between the entry and the stain show where insulation turns dry.
Wet boards are replaced and new membrane ties into firm roofing past the boundary.
The final boundary goes on a roof sketch so later leaks can be compared.

The stain sets nothing about the repair boundary. We find the source and how far moisture spread inside the roof first.
New work then connects to dry, firm materials, even when that edge reaches beyond what looked wet from inside the building.
Several yards is common on wide low-slope roofs. Water runs along deck flutes and soaks through insulation before it finds a joint to drip from, so the stain often sits downhill of the opening.
Wet boards come out. Covering them traps water that keeps dripping and softens the roof further, so soaked insulation is cut out and replaced before the membrane is sealed.
Usually, yes. Most warehouse repairs work from the roof, and the openings are small. Where a section is rebuilt over stock, we plan covers and timing with you first.
Photos of each stain, the dates they appeared, and a rough floor plan. Those let us match drips to the roof grid and walk the likely entry points first.
Not always. One stain with a clear entry nearby gets a focused trace and a few cores. Several stains across the building, or soft spots in the field, call for a wider grid of cores so the wet areas are found in one visit instead of over several storms.
Most warehouse roof repairs happen from above, so docks and aisles keep running. When material has to be hoisted near a dock, we pick a time with your shipping staff and keep the lift clear of trucks and forklifts.
Send photos of the ceiling stains and the dates they showed up. We trace and repair the roof above.
