As a Winchester commercial roof repair contractor, we fix leaking seams, flashing, fasteners, and drains on business, industrial, and farm buildings across Clark County.
Winchester commercial roof repair starts with how far the damage has spread. Find your roof in the rows below to see where repair fits and where a bigger plan takes over.
| Roof Condition | Repair | Restore | Replace |
|---|---|---|---|
| One or two leaks at a seam, curb, or drain | Usually Fits | Rarely | Rarely |
| Backed-out screws and cracked washers on metal panels | Usually Fits | Sometimes | Rarely |
| Worn surface with many small defects, dry insulation | Sometimes | Usually Fits | Rarely |
| Blisters spread across a built-up or modified bitumen field | Sometimes | Usually Fits | Sometimes |
| Wet insulation under large areas of the roof | Rarely | Sometimes | Usually Fits |
| Rusted deck showing through from inside the building | Rarely | Rarely | Usually Fits |
A moisture scan settles the middle rows. Wet boards under a small share of the roof get cut out and repaired first.
Each service starts with the symptom an owner usually notices first. Pick the one that matches your building.
Membrane, built-up, and modified bitumen roofs get repaired with the method each sheet was built for: hot-air welds on TPO and PVC, primer and cover tape on EPDM, new plies on gravel roofs.
Typical Repairs
Metal buildings leak at screws, end laps, ridge caps, and gutters. Crews work row by row along each purlin, swap worn fasteners, reseal laps, and replace rusted panels with matching profile and gauge.
Typical Repairs
Leak tracing begins at the stain and works upslope, matching it to curbs, seams, drains, and pipe boots above. Water travels along deck flutes and purlins, so the opening often sits well away from the drip.
Typical Repairs
Plant roofs get repaired in small sections around shifts, with lockout on moved units, hot work permits for torches, and floor barricades wherever rusted deck gets cut out from above.
Typical RepairsMove stock and equipment out of the drip zone, set a bucket, and call us. We start at the stain and trace the water back to the roof.
Most roof trouble shows up in two places at once. Match what you see inside to what is usually happening on the roof above it.
Drips along a straight line that follows the roll width overhead.
A TPO, PVC, or EPDM lap has lost its weld or adhesive, often near corners where the sheet flexes.
Pinhole drips in rows, usually near the eaves or the ridge.
Rubber washers have hardened and cracked, and panel movement has worked screws loose from the purlins.
Water around a diffuser or unit hanger after wind-driven rain.
Base flashing at a rooftop unit curb has split, or water piles up on the curb with no cricket behind it.
Stains near columns and interior drain lines after heavy storms.
Leaves and grit block the strainer, so water stands for days and pushes at nearby seams.
Soft or sagging ceiling tiles away from any curb or seam.
Moisture trapped between built-up or modified bitumen plies has pushed them apart into blisters.
Rust streaks or flaking on the underside of exposed metal decking.
Water drawn uphill into an end lap has rusted the lower panel edge until it holds moisture year round.
Every visit follows the same order, so the cause gets fixed instead of the symptom.
We walk the roof above the problem and check seams, flashings, curbs, drains, and fasteners nearby. Moisture readings show whether insulation under the leak has gotten wet.
Starting from the stain, the crew follows the deck flutes, purlins, and slope upward until the opening turns up. A hose test on one section narrows a hidden source.
You get photos and a short plain list naming each spot, what failed, and whether it calls for repair, restoration, or replacement.
Patches, reflashing, fastener swaps, and drain work go in with materials matched to the roof system so the fix bonds to what is already there.
After the next heavy rain, a look at the ceiling under each repair confirms it is holding. Notes go into the building record for the next inspection.
Small repairs done early keep water out of the insulation, which is what usually turns a patch into a large job.
Sealing a seam the week it opens keeps boards under the membrane dry, so the repair stays a patch and the roof keeps its insulating value.
Stopping drips over racks, machines, and offices protects what sits under the roof and keeps aisles and floors safe to use.
Fresh screws and washers on a metal roof keep water off the purlins, which slows rust at the laps and along the framing.
A repair visit that photographs each problem area lets you budget the next repairs or a restoration instead of reacting to the next storm.

Short answers to the questions that come up first on a roof repair call.
Any fix that brings a damaged part of the roof back to watertight without replacing the whole system counts as a repair.
On Winchester buildings that means resealing a TPO or EPDM seam, patching a hail puncture, reflashing a curb under a rooftop unit, swapping worn screws on metal panels, or resetting a clogged drain.
Nearly every commercial roof type takes a repair while the damage stays limited and the material underneath still holds a patch.
TPO and PVC get heat-welded patches, EPDM gets primer and cover tape, modified bitumen gets new cap sheet, gravel roofs get repaired in plies, and metal panels get fasteners, sealant, or a panel swap.
Price follows the size and spread of the damage, how much material has to come out, and how hard the roof is to reach.
Wet insulation, rusted deck found under the membrane, rooftop units that have to be moved, lift access, and matching an older roof system all add to a job. Catching a leak early keeps more repairs at the small end.
Small patch and seam repairs usually stay outside permit review.
When a permit is needed, it goes through the City of Winchester Building Inspections office, which covers the city and all of Clark County and reviews structures of 200 square feet or more. Deck replacement, new curbs, and structural work are the repairs to call that office about first.
Yes, most repair work happens from the roof while the building runs below.
Crews plan the roof access point, keep the area under deck work closed off, and finish each section watertight before leaving. Tell us about deliveries, shifts, and loading dock hours so the work fits around them.
As soon as you can schedule it, since water that reaches the insulation spreads out under the membrane.
A single wet seam can soak several boards before the stain inside grows. Photograph the stain, note the storm, and keep the drip zone clear until the crew arrives.
Tell us where the water shows up and what kind of roof sits above it. We will come inspect it and explain the repair.
Leave a name and number and we will call you about the leak or repair.
