Commercial roof repair
On a low-slope roof, water rarely drips where it gets in.
It slips under a lap, travels along the deck and shows up over a different office, aisle or bay, which is why a patch above the stain so often fails. A repair is only as good as the diagnosis behind it.
How we work
How we repair a commercial roof
Start with what you know.
Where water shows up inside, when it happens and what has been patched before tell the roofer where to start looking.
- Interior stains and drip locations
- Leaks tied to heavy rain or wind
- Past repairs and patches
Trace it on the roof.
A roofer works back from the leak area, checking every detail that could feed it, from seams and laps to the flashing at rooftop units, drain bowls, scuppers and the base of parapet walls, and photographs what they find.
Fixed to match the roof, with the building open.
You get a written scope and price, plus a note on anything else worth watching. The repair ties into the existing modified bitumen or other low-slope system, and timing, access and noise are agreed with your building contact so the building stays open while we work.
One record for owners, managers and tenants.
Photos of the problem and the finished repair give everyone the same picture. If the roof is worn across the whole surface, we’ll say so plainly, and those photos become the starting point for planning a commercial roof replacement.
Where leaks start
Where commercial roofs leak
Most leaks begin at details, not in the middle of an intact membrane. Condensate from an air conditioner or a plumbing leak can look the same, so a roofer checks those too.

Frequently Asked Questions
Straight answers about commercial roof repair.
Can you repair storm damage on a commercial roof?
Yes. When Santa Ana winds or a winter storm damage the roof or start a leak, call us: a roofer assesses and photo-documents the damage and adds temporary protection if it’s needed to limit further water damage. The permanent repair follows with a written scope and price, and our photos and scope can be shared with your insurance company. Learn more about emergency and storm-damage roof repair.
Our roof drain keeps backing up. Is that a roofing problem?
Often, yes. Debris can clog the strainer, the flashing around the drain bowl can fail, or low spots can keep water from reaching the drain at all. We check all three and repair the roofing side, and if the blockage is deeper in the drain line, we’ll tell you so a plumber can clear it.
Will you need access inside the building?
Sometimes. Seeing where water shows up inside helps us trace a leak, so we may ask to look at a ceiling or the area under a drain. Most repair work happens on the roof, and we’ll arrange any interior visit with you ahead of time.
Can you send the repair details to our owner or tenants?
Yes. Along with the written scope, you get before-and-after photos and a plain-English note on what failed and what we did. It’s easy to forward to ownership, file with your building records or share with the tenant who reported the leak.

How can we keep the next leak from happening?
Most commercial leaks start at details that wear gradually, like a drain that collects debris or sealant that dries out in the sun. Scheduled commercial roof maintenance catches those early and ends each visit with a photo report. If a repair is due, you’ll see a written price first.
