Curbs Too Low To Flash
A unit curb that barely clears the panel leaves no room for flashing. Water backs up behind it in heavy rain and finds the curb seam.
Montgomery County · Rooftop Units
We handle metal roof coating in Mount Sterling for retail, office, and warehouse buildings, sorting rooftop units, vent stacks, and gas lines before the coat.
Rooftop equipment causes more coating trouble here than the steel itself, so we sort it first.
Curbs under rooftop units often sit too low for proper flashing, vent stacks lose their rubber boots, and gas lines lie straight on the panels. Each one turns into a leak path once the field is coated around it.
Montgomery County's state listing names HVAC and plumbing inspectors, so changes to units or vent stacks involve those trades as well as ours. We line them up first, then seal the roof once, after their work is done.

Six conditions show up on most equipment-heavy roofs in town.
A unit curb that barely clears the panel leaves no room for flashing. Water backs up behind it in heavy rain and finds the curb seam.
Rubber boots on plumbing vents crack in the sun. The crack opens at the base, right where the stack passes through the steel.
Lines laid straight on the roof trap water and rub through coating. Supports lift them clear so the panel underneath gets coated too.
Units on low-slope steel block the flow. A small cricket behind the curb steers the water around it toward the eaves.
Condensate from rooftop units dribbles onto the panels when its line is clogged or loose. That constant wet spot rusts the steel beside the curb.
Service techs walk the same path to each unit for years. Screws along that route loosen and washers crack under the foot traffic.
On a Mount Sterling roof crowded with equipment, a coat finished after the trades pays off for everyone in the building.
Equipment-heavy roofs in Mount Sterling usually take one of these three.
Screws, laps, and rust get fixed, then the field and every curb are coated in one pass.
Low-slope steel that holds water behind curbs takes silicone once crickets are in.
Foam builds slope beside units and adds insulation under a topcoat.

We walk the panels and every unit, curb, and stack, then check inside for stains under the equipment.
HVAC and plumbing contractors raise curbs, swap vent boots, and lift gas lines before any coating starts.
Screws, laps, and rust get fixed across the field while the trade work wraps up.
Every curb and boot gets reinforced coating, then the field is coated to thickness in one finished pass.

The Kentucky HBC handles commercial construction permits here, because Montgomery County's state listing has no local building inspector.
That matters most when a job grows past coating, such as new panels over rust, new skylight framing, or a raised curb. Write the scope down in plain terms before you call.
Montgomery County's listing names an HVAC inspector and a plumbing inspector based at the county health department. Raising a curb, replacing a vent boot, or rerouting a gas line brings those trades in.
Booking them before coating means the roof gets sealed once, after their work.
Yes, as long as the curb sits high enough to flash. Reinforced coating is worked into the seam where the curb meets the panels and up the curb wall.
Curbs that sit too low get raised first, or water keeps finding that seam.
Units keep running most of the time. Intakes get shielded when coating is sprayed near them, and a unit gets disconnected only while its curb is being raised.
Those short shutdowns get scheduled with the building ahead of time.
Tell us how many units and vent stacks sit on the roof, roughly how old they are, and whether any changes are planned.
A unit due for replacement soon is best swapped before coating, so the new curb gets flashed and coated with the rest.
Foot traffic on the same path to each unit wears any roof surface over time. Walk pads along those paths protect the coating, and the screws on that route get checked at each visit.
Ask your HVAC contractor to mention any soft or dented panels they notice.
