THE SHORT ANSWER
Where do flat roofs usually leak?
Most flat-roof leaks start where the membrane is interrupted — drains, HVAC curbs, pipe penetrations, seams and old patches. That’s where we look first, and we photograph what we find so you can see it.
Commercial repairs we do
Flat roof repair
Built-up, modified bitumen and single-ply roofs — patches, drains, HVAC curbs, pipe penetrations and much more.
Shingle roofs
Repairs on commercial shingle roofs, backed by our Owens Corning Platinum Preferred training.
Tile roofs
Underlayment, flashing and broken-tile repairs on commercial tile roofs.
Can a flat roof be restored instead of replaced?
Often, yes. When the membrane is still sound, sealing the problem areas and restoring the roof can extend its life for far less than a replacement. If it’s failed across the roof, we’ll show you why.

Commercial flat roof leak along the walls in Marysville (95901)
Water was coming in along both walls of a first-story lab. Earlier repairs on both walls had failed. We removed the old membrane in the leaking wall and field areas down to the deck, installed new 60 mil TPO up the walls with new fastening plates and hot-welded seams, sealed the drains, and closed off the edge of the repair from the old roof with termination bar and a silicone seal.
Soft spots and dry rot on a commercial flat roof in Auburn (95603)
This TPO roof, with solar panels on it, had soft spots in four areas along the walls and in the open roof, about 150 sq ft in all. We cut out the membrane at each soft spot, replaced the rotted decking, installed new matching insulation and new 60 mil TPO secured with fastening plates, hot-welded and probe-checked the seams, then probe-checked the rest of the roof and sealed any open seams.
Elk Grove (95624): flat roof drain leak
Water was getting in at a roof drain and along the parapet wall of a commercial building. We sealed the open seams and drain with liquid flashing and coated the section in silicone.
