HVAC Curbs
Units vibrate, and their curb flashing loosens at the corners. Each curb is re-sealed and reinforced with fabric where the coating meets it. Fabric goes up the curb wall as well as across the panel.
As a Conshohocken metal roof coating contractor, we re-flash curbs, stacks, and pipe boots, then coat the roof around them so details stay sealed.


Roofs in Conshohocken often carry more equipment than open panel. Every Conshohocken metal roof coating job there starts at the penetrations: HVAC curbs, exhaust stacks, pipe boots, and conduit supports. Each one moves and corrodes on its own schedule.
We check flashing, sealant, and corrosion at every opening, rebuild what fails, and plan how technicians reach the units afterward.
Rebuilt details then get tied into the coating with reinforcing fabric and extra film, so the openings and the field move as one surface. We also mark the routes technicians use, so walk pads go where boots actually land and new flashing is left alone while it cures.
Penetration-heavy roofs leak at their openings first. These are the details we rebuild before coating.
Units vibrate, and their curb flashing loosens at the corners. Each curb is re-sealed and reinforced with fabric where the coating meets it. Fabric goes up the curb wall as well as across the panel.
Rubber boots crack in sun and cold. Split boots get replaced so coating ties into a sound collar. New boots are sized to the pipe, then sealed and coated.
Exhaust stacks rust at the base where water collects. That steel is cleaned, primed, and flashed again. Primer goes on the cleaned base before new flashing.
Blocks and straps holding conduit trap water and rub the panels. We lift or reset them so coating can pass underneath. Pads go under reset supports to protect the coating.
Service visits wear the same lines to every unit. Those paths get walk pads or heavier film. Routes get marked on a roof plan for the facility.
Layers of caulk around openings hide gaps. It gets cut back to clean metal before new sealant and coating go on. Cut-back joints are re-sealed with one compatible product.
With the openings rebuilt, the coating ties every penetration into one sealed surface.
Penetration-heavy roofs in Conshohocken usually get one of these plans.
Every opening rebuilt, then the field coated with a system matched to the panels. Each curb and boot gets fabric before the topcoat.
Flat zones around units, where water lingers, get silicone, tied into the panel coating. Fabric goes into the silicone at every unit base.
Pads on the routes to equipment, with an agreed schedule for service visits after coating. Technicians get the marked roof plan before their next visit.
Openings fixed now, with the field coating planned for the next budget year. Field coating can follow when the budget allows.
Areas disturbed by new units get detailed and tied into the existing coating. New curbs get flashed before coating is restored.
Call us. Leaks under equipment usually start at the curb or a nearby pipe boot, and we check those first.
These four calls set up a coating job on a roof full of equipment.
Every curb, stack, boot, and support gets checked, along with the panels and laps between them. Each opening gets a photo and a note on the roof plan.
Loose flashing, cracked boots, and corroded bases are listed and fixed before coating starts. Boots, flashing, and base metal are priced per opening.
Service calls are timed around the coating so new details cure before anyone kneels on them. The facility gets the coating dates in advance.
Panels and flat equipment zones may take different products, joined with a planned transition. Transitions get fabric and extra film at the seam between products.
Each penetration gets a final look once the coating cures, and owners get a list of the openings rebuilt for their service records. Leaks at a rebuilt detail get rechecked on the next visit.

Yes. Penetrations need sound, compatible flashing before the coating around them goes on. We check movement, corrosion, and old sealant at each opening, and coordinate equipment service so new details are left undisturbed.
Only firm, clean sealant that passes checks. Layered or cracked caulk is cut back so new sealant bonds to metal.
The count of penetrations matters most on these roofs. Planning ranges run about $2.50 to $4.00 per square foot, rising with curbs, stacks, boots, and the flashing work each one needs.
If your building is in Conshohocken or close by, call with the address and we will confirm coverage.
We coat commercial office, lab, and light industrial roofs in and around Conshohocken, starting with their penetrations.
The new curb gets flashed and the coating around it is cleaned, reinforced, and recoated to match. Calling before installation lets both trades plan the detail.
Only around overspray or when a curb is being re-flashed. Most work happens with equipment running, scheduled with the facility.
The facility contact and, where units need to be lifted or shut down, the HVAC contractor. We agree the timing with both before the work day.
Ask us to check the openings on your roof, or call to talk through the units and leaks you have.
