Short Curb Flashing

- What It Means
- Flashing stops below the snow line; it gets rebuilt higher.
As a Columbia City commercial roof repair contractor, we repair flat roofs where rooftop units, vents, and pipes pass through the membrane.

Columbia City commercial roof repair calls often lead to equipment and pipes added after the roof was installed.
Every new unit, vent, or conduit run cuts a hole in the membrane. When the flashing around it is rushed or too short, water gets in at the first heavy rain or snowmelt. Many flat roofs carry several generations of these penetrations.
We check each one, rebuild flashing to the right height, and add pads where service traffic wears the roof.

Penetrations come first, but the field and drains get checked too.
Sealing penetrations properly ends the leaks that keep returning around equipment.
Flashing at the right height keeps snowmelt and wind-driven rain from topping the curb around each unit.
Walkway pads on the path to each unit take the wear from technicians and their tools.
Old curbs and pipes left from removed equipment get capped or removed so they stop collecting water.
Seams, drains, blisters, and edge metal are inspected in the same visit and listed by urgency.
Penetration repairs fit most roofs. The readings around each one show when the scope grows.
That usually points to the curb above it. Call and we will trace it and rebuild the flashing.
Call Us(574) 384-0858Each penetration gets the same set of decisions.
Every curb, pipe, vent, and conduit run gets checked, along with seams, drains, and edges. Inside, stains get matched to the equipment above.
Moisture readings around each curb and boot show which ones let water in and how far it spread.
Working equipment gets new flashing at full height. Abandoned curbs and pipes get capped or taken out.
Curb work needs some units off for a short time, scheduled with your HVAC contractor or maintenance staff.
Walkway pads go on the service paths, and you get a photo map of every repaired penetration.

Answers for owners and managers of flat roofs in Columbia City.
TPO, EPDM, built-up, and modified bitumen roofs on commercial buildings. Open seams, drain flashing, blisters, and damaged edge metal are the usual repairs, and wet insulation under a leak gets replaced so the patch seals over dry material. Each patch uses the same membrane as the roof around it.
The curb flashing gets checked for height and splits, the unit base and condensate lines for open joints. Failed flashing comes off, new flashing goes on at full height, and a walkway pad protects the service path.
The number of penetrations to reflash, the size of any wet area, whether units must be shut off or lifted, and roof access set the price. It is priced after a free inspection.
Yes. One leaking pipe boot or a single curb is a job we take, with the same inspection and photo report as a larger repair. While we are up there, the rest of the roof gets a walk so any other weak curbs or seams make the list.
Yes. Curbs left from removed units get torn out and the deck opening closed with new decking, insulation, and membrane. Where removal is impractical, the curb gets capped and flashed so it stops holding water against the roof.
