Flat roof repair
Water on a flat roof moves slowly and finds every weakness.
It can travel under the membrane before it drips, so the stain on your ceiling may sit far from the opening. That’s why we check the whole area around a leak, not just the spot above the stain.
How we work
How we repair a flat roof
Check the whole area. Find the opening.
A roofer works around and upslope of the leak until the cause is found, and photographs it before anything is fixed.
- Seams, laps and blisters
- Parapet caps and wall flashings
- Drains, scuppers and equipment curbs
- Vents and skylights
Repair with what your roof is made of.
Damaged membrane is cut out, open laps are resealed and failed flashings are rebuilt, with materials that work with your existing roof system.
Open drains. A repair that stays dry.
We make sure nearby drains and scuppers are clear, because a repair lasts longer when water isn’t standing on it.
Patch or replace, said plainly.
A targeted repair makes sense when the rest of the roof is in reasonable shape. If the membrane is worn out across the surface, we’ll tell you that more patching only delays a flat roof replacement. Either way, the scope and price are in writing before we start, and you get photos of the finished repair.
Where leaks start
Where flat roofs leak
Most leaks begin at details, not in the middle of an intact membrane: the drains, seams, flashings and everything that passes through the roof.

I had a problem with water leaking into my attic from the flashing around the chimney, and the team was very helpful from the start. Tony was the roofer working with me, and he was always professional and friendly. He took care of resealing the flashing and chimney, which made the leak much better right away. He kept in touch with me after the work, and now we’re working on sealing the chimney even more to make sure everything is perfect. I feel confident that the team will get everything fixed up right. Based on my experience so far, I’d definitely give them five stars. Thanks to everyone there for their hard work!”

Frequently Asked Questions
Straight answers about flat roof repair.
Why does my flat roof leak in big storms but not light rain?
Light rain may drain away before it finds a weak spot, but a heavy storm deepens the water on the roof and pushes it into open laps, cracked flashings and overflowing scuppers. Water that’s still ponding after the storm is a clue that drainage is part of the problem. A flat roof inspection shows you where the water is getting in.
Can you fix blisters on a flat roof?
Yes. Small blisters that are still intact are often left alone and watched, while cracked or growing blisters are cut out and patched. We’ll show you which ones need attention and explain why.
The leak is near a wall. Is it the roof or the wall?
It can be either. On roofs with parapets, water often gets in through cracked parapet caps, gaps in the stucco or failed wall flashings rather than the roof surface itself. We check the parapet from cap to base and tell you exactly where the water is entering.
Do you repair flat roofs on garages, patio covers and additions?
Yes. These smaller low-slope roofs leak for the same reasons as the main roof, usually at the seams, the drainage or the joint where they meet the house. They get the same photo-documented approach as any other repair.

What if you find more than one problem?
We photograph each one and list it in your written scope, so you can decide what to fix now. If the roof is sound overall but has a handful of small issues, a flat roof tune-up may cover them in one visit.
