Commercial Roof Repair in Wausau, WI
Water rarely gets into a commercial roof where it shows up inside. It enters at a flashing, a seam, a pitch pocket around a rooftop unit or a cracked drain bowl, then runs along the deck or under the insulation and drips out somewhere else: over a desk, a stock shelf or a production line. Finding where it gets in is the whole job. We trace the leak on the roof, photograph what failed, and give you a written price before any work starts. In central Wisconsin the same culprits come up every year: seams and flashings worked loose by a long winter of freeze and thaw, meltwater backing up behind snow and ice at the drains and parapets, punctures from snow shovels and HVAC service traffic, and spring rain arriving before the drains have thawed.

Sound like your roof?
Not sure what is wrong or what it should cost? If any of these sound familiar, tell us about the roof. We'll tell you what it probably is, then confirm it on the roof and give you a written price before any work starts.
- Ceiling tiles stained or sagging after rain or a thaw
- Water dripping near light fixtures, columns or along an outside wall
- Leaks that only show up when snow on the roof starts to melt
- Membrane seams lifting, blisters, or bare spots in the gravel
- A leak that keeps coming back in the same place after someone patched it
Leaking right now? Protect the inside first
Move inventory, files and electronics away from the drip, shut off power to any light fixture or panel that is getting wet, and put down buckets or plastic. Keep people out from under a ceiling that is sagging with water above it. Don't send staff onto the roof during a storm, in the dark, or when it is icy or snow-covered. Low-slope roofs have skylights, open edges and slick membranes. Then request service: an active leak can usually be dried in temporarily until a permanent repair is possible.
From the first call to a dry roof
Tell Us About the Roof
The building, the roof type if you know it, and what is happening: an active leak, a stain, ponding water, storm damage, or a roof that is just getting old. Active leaks go to the front of the line.
Roof Assessment
We walk the roof, trace the problem, check the drains and flashings, and take core samples or moisture readings where the insulation might be wet.
Written Options and Price
You get a written scope and price. When more than one approach makes sense, repair, coating and replacement are laid out side by side with what each one buys you.
Work Done and Documented
The work is done to the manufacturer's specification, and you get a photo report and any warranty paperwork for your files.

Most leak repairs, such as a seam, a flashing, a pitch pocket or a drain, run about $350–$2,500. Repairs that cut out and replace wet insulation, or rebuild long runs of parapet flashing, cost more. You get a written price before work starts. Replacement and coating costs are in the cost guide.
Usually because the patch went over the stain, not over the entry point. Water often gets in several feet, or several bays, away from where it drips. Tracing the leak to the actual seam, flashing or drain fixes it. See how flat roof leaks are found and fixed.
Meltwater runs to the drains under the snow. If a drain or scupper is frozen, the water backs up behind ice and sits against seams and flashings that never see standing water in summer. Opening the drains stops today’s leak; sealing the weak detail stops next year’s. See ice dams on flat roofs.
Many repairs, yes. Some adhesives, primers and coatings need dry surfaces and minimum temperatures, so in a cold spell we make a temporary repair to stop the water and come back for the permanent one when conditions allow. More in roofing in a Wisconsin winter.
We work on all the common low-slope systems: EPDM, TPO, PVC, modified bitumen, built-up tar-and-gravel roofs, and metal roofs. If a roof is under a manufacturer warranty, tell us, because repairs on it may need to follow that manufacturer’s specifications.
