Russellville metal roof coating planned around rooftop HVAC. We measure every curb first, then seal and coat so units keep running.
1Measure The Curbs
2Seal Around UnitsThe Russellville Angle

On Russellville metal buildings, rooftop HVAC units decide much of the work. Curbs, duct transitions, and condensate lines all pass through the panels.
A coating over existing steel leaves those units alone. Foam or new curbs raise them, and the city then asks for HVAC plans before the state permit. We sort out which path fits on the first roof walk, before anything is priced.
Russellville Roof Signs
HVAC units bring service traffic and water to the roof. These show up most.
Runoff dams on the uphill side of each curb and rusts the flashing first.
Lines that empty onto the roof keep one patch of steel wet all summer.
Technicians walking the same line scuff paint off the panel ribs to bare metal.
Dropped screws from service visits puncture coatings and roll into gutters.
Low curbs leave no room for foam without raising the unit.
Water at a supply grille means the curb or duct boot is leaking now.
For Russellville Buildings
These hold when curbs are flashed and sealed first.
Each curb gets fabric and base coat on its uphill side, where water dams against it after every rain.
A coating-only job keeps units in place, so no HVAC plan review is needed.
A light top coat cuts the heat load on the roof around condenser coils.
Granulated walk paths guide HVAC technicians to each unit and protect the coating from boots and dropped tools.

Russellville Job Sequence
Curbs get settled first because they decide whether permits come into it.


We measure every curb, trace condensate lines, test panels around units, and note any unit that has to move.
Coating only keeps units where they are. Foam or new curbs go to the Building Official with HVAC plans first.
Panels get washed, condensate lines get piped to gutters or drains, and loose screws get replaced.
Curb corners and duct boots get fabric in base coat before the field is touched.
Field coats go on, then granulated paths mark the service route to each unit.

Answers for Russellville owners with rooftop equipment.
HVAC Plans
The City Building Official takes permit applications, and the city uses the International Building Code for commercial work. When units move or get replaced, HVAC plans and load calculations go to the Building Official before the state HVAC permit.
A coating-only job over existing panels keeps that step off the schedule. If foam or new curbs raise the units, plan curb heights and duct transitions early so the plans are ready before the crew arrives.
Power Provider
Russellville Electric Plant Board serves inside city limits, with close to 4,000 accounts in TVA's directory. Buildings outside town can be on Warren RECC lines.
Either way, the provider matters when units shut down for spraying, and conduit straps through the panels need their holes sealed.
Curb Height
A coating adds only mils, so existing curbs stay as they are. Foam adds inches, which can bury short curbs and flashing.
We measure each curb against the planned finished surface before recommending foam, and list any unit whose flashing would end up buried.
Condensate
Into a gutter, drain, or splash block off the panels, instead of onto the roof surface.
Constant drip keeps one patch of steel wet all summer and wears coatings fastest there, so rerouting lines is part of the prep. A short run of pipe to the gutter usually does it.
Service Visits
Not if they use the marked paths. Granulated walk paths take the traffic, and dropped screws get picked up during maintenance.
Ask service companies to report any gouge so it can be patched before water gets under it.
Unit Replacement
If a unit is near the end of its life, swap it first. Pulling a unit after coating means cutting through the new film around its curb.
Ask your HVAC contractor about timing during the roof walk. The new curb and flashing then get coated with the rest of the roof, and the city plan step happens once.
Foam Option
When the building has little insulation and the steel drips in winter. Foam fixes that, but it raises the roof surface around every curb.
Units with tall curbs handle it easily. Short curbs need raising first, which brings the HVAC plan review, so we price both paths for you to compare.
