Has one split seam or a torn flashing corner
Cleaning and a hot-air weld or primed tape close the lap, and the rest of the field stays as it is.

Is This Roof a Fit for Flat Roof Repair?
A Henderson flat roof repair contractor starts with the membrane type and how wet the boards are. These four cases show where a flat roof job begins.
If Your Roof
Holds water for days after a storm
Clearing the outlets comes first, then crickets or tapered insulation can correct the low bay.
Start WithDrainage Repair
If Your Roof
Shows bubbles across a modified bitumen surface
Large or broken blisters get cut out, dried, and patched, and small stable ones get marked and watched.
Start WithBlister Repair
If Your Roof
Feels soft underfoot across whole sections
Wet insulation across the field means patching would chase leaks, so core cuts decide the next step.

What a Henderson Flat Roof Repair Contractor Finds on Low-Slope Roofs
Flat roofs show trouble inside first. Each pair links what you see in the building to the part of the membrane that let water in.
Stain Near A Rooftop Unit
A ring spreads on the ceiling under a unit or exhaust fan after rain.
Split Curb Corner
Flashing at the curb corner opens up, and water runs under the membrane toward the drip point.
Sagging Ceiling Tiles
Tiles bow and turn soft along one bay of the building.
Open Field Seam
A TPO weld or EPDM seam tape lets go, and water spreads through the insulation before it shows.
Drip After Service Work
New drips show up a week after the HVAC contractor was on the roof.
Puncture From Dropped Screws
A dropped screw or tool, stepped on, pushes through thin or aged membrane along the service path.
Water At The Back Wall
Water runs down the inside of an exterior wall near a downspout.
Blocked Scupper Or Drain
Leaves and a crushed strainer stop the outlet, and backed-up water finds the drain flashing.
Commercial Roof Repair Options for Henderson

| Seam Weld Or Tape | TPO laps rewelded, EPDM laps primed and taped, cover strips on aged seams | One or a few open laps with dry boards underneath |
| Blister Cut And Patch | Loose membrane cut away, area dried, matching patch lapped past the cut | Large or broken blisters on modified bitumen and built-up roofs |
| Puncture Patch | Matching membrane patch over the hole after the board below is checked | Holes along service routes and hail marks on thin membrane |
| Drain And Scupper Repair | New strainers, retightened clamping rings, patched drain flashing, reflashed scupper boxes | Outlets that back up or leak at the bowl |
| Ponding Correction | Lowered drain sumps, crickets at rooftop units, tapered insulation in a low bay | Water that stays on the roof after storms |
Benefits of Repairing Your Roof
Flat roof repairs pay off where water collects. Each row names the spot where you see the result.
- Seams
Laps That Shed Water Again
Rewelded TPO laps and retaped EPDM seams close the gaps water uses to reach the insulation, so the field around them keeps working as one sheet.
- Insulation
Boards Stay Dry And Firm
Catching a puncture before it soaks the board keeps the roof firm underfoot, and a dry board under a patch is a board that stays in place.
- Drains
Faster Drainage After Storms
Strainers, clamping rings, and cleared scuppers get water to the outlets, which takes weight off the deck and slows membrane wear in low bays.
- Walkways
Fewer New Holes On Service Paths
Walkway pads along the routes HVAC crews use put a wear layer between boots, dropped screws, and the membrane.
Water Standing on the Roof?
Ponding that stays after a storm finds weak seams and adds weight to the deck. We clear the outlets and find the low spot.

Flat Roof Repair Visits in Henderson
Each flat roof visit follows the same order, so wet boards are found before any patch goes on.
What The Inspection Covers
- Membrane type and age
- Field seams and laps
- Curb corners and pipe boots
- Drains, strainers, and scuppers
- Moisture readings and core cuts
- Service routes to units
- 1
Inspect Your Roof
We walk the field and the edges, probe seams with a seam tool, and take moisture readings around every stain location and soft spot.
- 2
Open Up Suspect Areas
Blisters get cut, punctures get checked, and a core cut shows whether the insulation under a damaged area is wet.
- 3
Replace Wet Boards
Soaked insulation comes out and new board goes in, so the patch sits on a dry, firm base and the leak stays gone instead of returning as a soft spot.
- 4
Weld Or Tape The Repair
TPO and PVC get hot-air welds, EPDM gets primer and seam tape, and modified bitumen gets a matching cap sheet patch.
- 5
Clear And Test Outlets
Drains and scuppers get cleared, missing strainers get replaced, and every new weld gets probed before the crew comes down.
Related Repairs for the Same Building

Many shops have a flat office wing beside a metal warehouse roof, so both roofs get checked on one visit.

Plant roofs add exhaust residue and heavy foot traffic to the usual seam and drain work.

Question about your own roof?
Call UsWhy do blisters form on a flat roof, and should they be cut open?
Trapped moisture or air expands under the membrane on hot days and lifts a bubble between the plies. Small blisters that stay put get marked and watched.
Large or broken ones are cut out, the area is dried, any wet insulation is replaced, and a matching patch goes over the cut. A cluster of blisters points to deeper moisture, so core cuts come before more patching.
What fixes ponding water on a commercial flat roof?
Getting water to the outlets faster. The first step is clearing debris from drains, strainers, and scuppers.
If water still sits in a low bay, the fixes grow from lowering a raised drain sump, to adding crickets around rooftop units, to tapered insulation or a new overflow scupper. A sagging deck under the pond needs an engineer before any roofing work.
How are split seams repaired on TPO and EPDM roofs?
TPO seams are cleaned with membrane cleaner and rewelded with hot air, and a welded cover strip goes over laps that have aged. EPDM seams are cleaned, primed, and resealed with seam tape and a cover strip.
When years of sun leave old TPO that refuses a test weld, a cover strip or patch takes the place of rewelding the original lap.
How is a puncture in a flat roof membrane fixed?
Clean around the hole, check the board underneath for water, and cover the damage with matching membrane that laps past it on every side.
Punctures on Henderson roofs come from dropped tools and screws during HVAC service, hail on thin membrane, and boots grinding debris into the sheet. Walkway pads on service routes cut down on new holes.
What repairs do clogged roof drains and scuppers need?
Clearing comes first, then a look at the strainer, the clamping ring, and the flashing at the bowl, since backed-up water finds every weak spot around an outlet.
Crushed or missing strainers get replaced, loose clamping bolts get retightened, split drain flashing gets patched, and rusted scupper boxes get reflashed or swapped. Fall leaves are the main reason outlets clog here.
