As a Fremont commercial roof leak repair contractor, we trace each stain to the roof detail letting water in and seal it there.
Fremont commercial roof leak repair closes one entry point. Sometimes the trace shows the roof needs a bigger fix.
Water usually enters at a detail and shows up somewhere else. These are the sources we trace most.
Curb flashing, cabinet seams, and condensate lines all leak at rooftop units. Each path gets tested separately.
Dried glazing seals, cracked domes, and folded flashing at curb corners let water past skylights.
Hail splits brittle membrane, cracks skylights, and dents flashing. Active leaks get a temporary seal before photos and repairs.
Counterflashing pulls away from masonry and lets water run down behind the membrane at the wall.
On flat roofs, an open lap several feet away feeds the stain you see. Moisture readings find it.
Pipe boots, conduit supports, and sign mounts crack where they meet the membrane and leak a little at a time.
Each leak source gets a matching repair, and each has a point where the fix turns into a larger project.
| Source | Repair We Make | Bigger Job Signal |
|---|---|---|
| Rooftop unit curb | Reflash the curb, seal cabinet seams, clear condensate lines | The curb itself is rotted or rusted |
| Skylight | Reseal the frame, reflash the curb, or replace the dome | Several skylights fail at once |
| Hail split | Patch splits, replace cracked domes, document impacts | Impacts cover the whole roof |
| Wall flashing | Reset counterflashing and seal the termination bar | The parapet wall is wet inside |
| Pipe boot or support | Replace the boot or flash a new support pad | Many penetrations show the same wear |
Finding the real entry point means paying for one repair instead of three guesses.
Water travels under membranes and along deck flutes, so the drip is rarely below the hole. Tracing with moisture readings and a water test pins the entry point, and the repair goes there instead of over the stain.
Ceiling tile, drywall, and finishes stop taking new water once the source is closed.
Storm and hail leaks come with dated photos and notes owners can pass to an insurer.
Early repairs keep insulation from soaking up water across a whole bay.
Call and describe where the water lands. We set a temporary seal on the active leak, then trace and repair it once the roof dries.
(402) 407-4074Call UsLeak work starts inside and ends on the roof, with a check back inside after the next rain.
Stains, drips, and wet stock go on a floor plan with the bay, column line, or room so the roof search starts above them.
We check curbs, seams, skylights, and penetrations above and upslope of the marks, with moisture readings across the area.
Water runs on one suspect detail at a time while someone watches inside, which confirms the entry point.
The failed flashing, seam, boot, or skylight seal is repaired with materials that match the roof system.
Marked ceiling spots are checked after the next rain to confirm the stain stopped growing.
Once the source is found, the fix often belongs to one of these repair types.
Drains, laps, or blisters found during a trace on a low-slope roof get the full flat roof repair for that area.

Screws, laps, or trim at fault on a steel roof get new fasteners, resealed laps, or matched panels.

Fan curbs, stacks, and process exhausts that leak get plant-grade flashing and membrane repairs.
Fremont industrial roof repairAnswers on tracing, rooftop units, hail, winter repairs, skylights, and cost.
Start with a floor plan. Mark drips, stains, and wet stock, then walk the roof above and upslope of those marks, checking penetrations, seams, and skylights. On big roofs, infrared or moisture meters narrow it down, and a water test on the suspect area confirms the source before any repair.
Three paths are common: the curb flashing, the unit cabinet seams, or a backed-up condensate line. Technicians walking around the unit also wear the membrane nearby. Each path gets tested on its own, then the curb is reflashed or the cabinet sealed as needed.
Stop the water first, then take dated photos of the damage. Hail splits brittle membrane, cracks skylights, and dents metal flashing. Active leaks get temporary repairs, impacts are marked across the roof, and the documentation goes to the owner for the insurer.
Many can, with temporary or cold-weather methods. Snow and ice are cleared from the work area first. Some adhesives and sealants need a minimum temperature, so the permanent repair can wait for a warmer day while the temporary one keeps water out.
Curb flashing fails, glazing seals dry out, or the dome cracks from hail or age. Water also gets in at curb corners where flashing is folded. The dome, frame seals, and curb are inspected, then resealed, reflashed, or replaced.
Most of the cost is in finding the leak and reaching it. A single curb or boot repair is small; tracing water across a large roof, testing several suspects, or cutting out wet insulation adds hours. Access, roof height, and the membrane type set the rest.
Tell us where the water shows up inside. We will trace it to the roof, seal it, and check it after the next rain.
