Curb Flashing Repair in Fortville
Cracked or short flashing at HVAC curbs lets water over during heavy rain. Taller, resealed flashing keeps it out. New flashing is run up the curb and sealed under the unit rail.


As a Fortville commercial roof repair contractor, we repair curb flashing, pipe boots, and service-path wear around the rooftop units on flat and metal business roofs.
Fortville commercial roof repair on shops and offices often centers on the equipment up top.
Rooftop units, exhaust fans, and gas and condensate lines each break through the roof. Service techs then walk the same path to them every season, and the membrane along that path wears thin.
So the walk covers each curb, boot, and line support, and the paths between them. Repairs reflash the curbs, replace split boots, and add walkway pads where feet keep landing.

Equipment-heavy roofs on Fortville businesses wear in these six places.
Cracked or short flashing at HVAC curbs lets water over during heavy rain. Taller, resealed flashing keeps it out. New flashing is run up the curb and sealed under the unit rail.
Service traffic wears paths into membrane. Pads laid along those paths take the foot traffic instead. Pads also mark the safe route to each unit for the next technician.
Rubber boots around gas and vent pipes crack in sun and cold. New boots and clamps seal them. Pitch pockets around odd-shaped supports get topped off or rebuilt.
Laps beside units get stepped on and flexed. Rewelded or taped seams hold up again. A walkway pad placed over that stretch keeps it from happening again.
On metal business roofs, screws near units loosen with vibration and let water along the row. Oversized screws with fresh washers grip the worn holes.
Unit condensate lines that drain onto the membrane keep one spot wet. Rerouting them to a drain helps. Algae around a wet spot is often the first clue on a white membrane.
Most leaks around rooftop units end at the curb. A few point to the roof around it.
| What We Check | Curb Repair Covers It | Plan For More Work |
|---|---|---|
| Curb flashing | Cracked or short, curb solid | Curb itself rotted or loose |
| Membrane near units | Worn along one path | Worn across the equipment area |
| Insulation | Dry beside the curb | Wet around several units |
| Unit changes | Same unit, same curb | New unit needing a new curb |
Sealing around equipment protects the rooms the units serve.
Rooftop units often sit over offices, sales floors, and kitchens. Reflashed curbs and new boots keep water out of the ceiling right where people work.
Walkway pads spread service traffic off the membrane. They cost little next to a torn membrane.
New boots stop drips around gas and vent lines. Clamps get tightened so the boot moves with the pipe.
Repairs happen up top while the shop stays open. Noisy steps get timed outside your busiest hours.
Call and tell us which unit. Curb flashing and boots are quick to check and quick to reseal.
Equipment roofs get a unit-by-unit check.
Every curb, boot, condensate line, and support gets checked, with flashing heights measured. Units with past leak history get the closest look.
If a unit needs to be shut down or moved, timing gets set with the owner and their HVAC contractor.
The scope lists repairs by unit, plus walkway pads along service paths. Any unit with a rotted curb is flagged for the owner and their HVAC contractor.
Curbs get new flashing, boots are replaced, worn seams are repaired, and pads go down on the paths. Condensate lines draining onto the membrane get rerouted to a drain where possible.
Before-and-after photos for each unit go to the owner for the building file.
Three equipment details shape repairs on Fortville business roofs.
Short curbs let water reach the top of the flashing in heavy rain. Taller flashing fixes it without moving the unit.
Gas, electrical, and condensate lines each pass through the roof with their own boot or pitch pocket to seal.
Units serviced several times a year wear the membrane faster, which is where walkway pads earn their place.
Along with Fortville, we repair commercial roofs in Anderson and four other towns.

Rooftop units, boots, and business roofs in Fortville.
Curb flashing cracks or sits too low, and seals around ducts and lines dry out. Water then runs into the ceiling below the unit.
Yes. Pads along service paths take foot traffic off the membrane and keep it from wearing thin.
Both. On Fortville shops and offices that usually means closing seams, swapping damaged flashing, replacing leaking screws, and resealing drains.
We explain what caused each problem, so the owner knows whether a repair is enough or the roof is near replacement.
Most can, since the work stays on the roof. Noisy steps or unit shutdowns get timed with the owner.
Only when a unit must be moved or opened. Otherwise the curb and boot work goes ahead on its own.
Rubber boots harden in sun and cold, then crack where the pipe flexes. A new boot and clamp seal the pipe again.
A small collar filled with sealant around odd-shaped supports. When the fill shrinks, it gets topped off or rebuilt.
Tell us which units and where the water shows. We will check every curb and boot and write up the repair.
