As a Kingston commercial roof repair contractor, we close old curbs, flash new ones, and repair leaks left behind by rooftop equipment changes.
Replacing a rooftop unit often leaves the old curb, unused pipe supports, and open holes behind. A Kingston commercial roof repair contractor closes each one, because a curb capped with plywood or an empty pitch pan is a common leak source.
Kingston is an unincorporated community in Madison County, where electrical permits go through the county office. New equipment usually needs electrical work, so the roof repair and the wiring are planned together.
Equipment changes leave a trail of small openings on Kingston roofs. The featured one causes the most leaks.
When a unit is removed, the curb is sometimes covered with plywood and left in place. The wood rots, the flashing around it splits, and water runs straight into the opening the unit used to fill.
Usually MeansRemove the curb, infill the deck, and patch the roof over it.
Water dams on the uphill side of a new curb and works into the corner flashing.
Unused supports on blocks wear holes in the membrane underneath.
Pans with no pipe left in them shrink and crack, then leak around the base.
Dropped screws and panel edges pierce the sheet along the path the install crew walked.
Closing every opening after an equipment change keeps the new unit from bringing new leaks.
Equipment-related repairs in Kingston come down to these four jobs.
Abandoned curbs are removed, the deck opening infilled, and the membrane patched over it. A curb kept for later gets a sealed metal cap.
New curbs get flashing run up the sides and under the counterflashing, plus a cricket on the uphill side so water flows around them.
Unused supports are pulled and the membrane under them patched, and empty pitch pans are sealed or removed so nothing is left open.
Where new units need wiring, electrical permits go through the county office, and the electrician and roofer share the schedule, so the curb is flashed right after the unit is set and before the next rain.
Plan the old curb closure and the new curb flashing alongside the install. Send us the address and the equipment schedule.
Repairs around an equipment swap work best when they follow the install.
Before the swap, the roofer walks the roof and marks every curb, support, pitch pan, and pipe that the change will leave behind or affect.
Once the old unit is out, its curb is removed or capped, the deck infilled, and unused supports and pans are pulled and patched.
Flashing goes up the new curb and under the counterflashing, and a cricket is added uphill so water runs around it.
After the install, the path from the hatch to the unit is checked for punctures and debris, and photos go to you.

Abandoned curbs, unused pipe supports, and open holes where old units sat. Each needs a closure: remove the curb and infill the deck, cap a curb kept for later with sealed metal, pull unused supports and patch under them, and seal or remove empty pitch pans.
Kingston is unincorporated, in Madison County, and electrical permits there go through the county office. When a new unit needs wiring, the electrician pulls that permit, and the roof work around the curb is scheduled to match. Agreeing on the dates early keeps the old opening from sitting open between the electrical and roofing work.
A curb blocks water flowing down the roof, so it dams on the uphill side and works into the corner flashing. A cricket splits the flow around the curb, which keeps the flashing from sitting in water. Crickets are built from tapered insulation under the membrane, so they become part of the roof around the curb.
Remove them when the opening will never be used again, then infill the deck and patch the roof. Cap them with sealed metal only when new equipment will go back in that spot. Either way, the opening is closed as soon as the old unit comes out, so rain has no path into the building.
Ask them to carry off screws, panels, and cut-offs, use walkway pads along their route, and schedule a roof walk after the work. Punctures found right after the install are quick patches. Keeping a roof access log also ties any damage to the visit that caused it, which makes it easier to sort out who repairs it.
Tell us about the equipment change and the roof, and we will plan the closures and new curb flashing.
Leave a name and number and a roofer will call you back about the leak or damage.
