If Your Roof
Has Firm Panels And Leaks At The Screw Rows
Washers have dried out but the steel holds, so fastener work and a full coat stop the drips.

R-Panel And Standing Seam Roofs
Bardstown Commercial Metal Roof Coating
Commercial metal roof coating for Bardstown warehouses, shops, and equipment buildings. We treat the rust, fix every exposed screw, seal the laps, then coat the panels.
Quick Facts
- Red and white rust primed
- Stripped screws upsized
- End laps sealed full width
- R-panel and standing seam
Is This Roof A Fit?
A metal roof coating works over steel that is still solid. These four situations cover most of the commercial metal roofs we walk around Nelson County.
If Your Roof
Is Standing Seam With Lifted Seams At The Splices
Hidden clips stay put while seams and end splices get sealed, after the panel brand is checked.
Start WithSeam Sealing And Coating
If Your Roof
Has A Few Rusted-Through Sheets Near The Gutters
Those sheets are cut out and matched with new panels, and the field is then primed and coated.

If Your Roof
Sags Between Purlins Or Has Rusted Framing
A coating adds no strength, so structural repair or a new roof comes before anything else.

What Fails First On A Metal Roof
Exposed-fastener R-panel roofs leak at the parts that pierce or overlap the sheet. These rows show the usual trail from stain to cause.
Rusty Fastener Tips Above The Racking
Likely Cause
Wallowed screw holes let the sheet move, so the washer never seals no matter how tight the screw gets.
What We Do
Remove the screw, upsize to the next diameter, cap the head, then prime and coat.
Orange Streaks Below The End Laps
Likely Cause
Debris collects at the step where the upper panel overlaps the lower one, and the tape inside dries out.
What We Do
Clean out the lap, seal it across the full panel width, and reinforce it with fabric.
Chalky Powder On Galvalume Panels
Likely Cause
White rust forms on galvanized or Galvalume coatings that stay damp, and paint sheds as chalk with age.
What We Do
Wash with a maker-approved cleaner, then apply the primer listed for that surface.
Rattling Rake Trim On Windy Days
Likely Cause
Trim screws back out and wind lifts the edge, which opens a path for rain behind the panel ends.
What We Do
Refasten the rake and eave trim, seal the joints, and carry coating onto the trim face.
Commercial Roof Coating Options for Bardstown
Several systems go over primed steel. The choice depends on how fast the roof drains, how much foot traffic it sees, and what you want at the next recoat.
Acrylic Over Primed Steel
Gable roofs and steady pitches drain within hours, which suits water-based acrylic. It stays bright and accepts many coatings at the next recoat.
Silicone Over Primed Steel
Shallow R-panel roofs that hold water at end laps or behind rooftop units take silicone, which handles standing water better than acrylic.
Foam Plus A Top Coat
Closed-cell foam over the ribs adds insulation and buries screws and laps in one layer. It raises the roof edge, so trim gets reworked.
Benefits of Coating Your Roof
These are qualified gains. Each holds only when the rust, screws, and laps are handled before the coating goes on.
Keeps Solid Panels On The Building
Coating a roof with firm panels costs less than tearing off steel that still has years of use in it. The screws, laps, and rust spots get fixed, and the panels you already own stay in place under one waterproof film.
Rust Slowed At The Laps
Primer plus coating keeps dew and rain off the hidden steel inside panel overlaps, where rust starts first on R-panel roofs.
Work Stays Above Your Racking
Crews work from the roof surface, so shelving, equipment, and stock inside stay where they are while the coats go on.
Future Recoats Instead Of Tear-Off
When the top coat wears thin years later, a cleaned roof takes a fresh coat of the same family over the existing film.
Rust Stains Spreading From Your Laps?
Send photos of the end laps and screw rows when you call. Rust that stays on the surface is usually ready for primer and coating.
Our Metal Roof Coating Sequence
Exposed-fastener roofs need far more detail work than standing seam roofs. This is the order we follow on each of them.
- Step 1:
Inspect Your Roof
We walk the panels between purlins, check every screw row and lap, and read the panel brand on standing seam roofs. From inside, stained purlins and wet insulation show where water has been landing.
- Step 2:
Grade The Rust
Surface bloom, red rust at laps, white rust on Galvalume, and rust-through holes each get marked on a roof sketch. Holes get patched or the sheet gets swapped before prep moves on.
- Step 3:
Clean And Prime
Panels are pressure washed, loose scale comes off with wire brushes, and the primer listed by the coating maker goes on every rusted area and any surface that calls for it.
- Step 4:
Fasteners, Laps, And Trim
Screws are tightened, upsized, or added at end laps and ridge caps. Laps get mastic or seam tape with fabric, and lifted trim is refastened before the base coat.
- Step 5:
Base Coat And Finish Coat
Two coats go on at the film thickness the product sheet calls for, with the finish coat in white or a light color unless the building calls for another.
Other Ways To Coat A Metal Building
Some metal roofs need a different finish or added insulation. These services cover those cases.
Silicone Roof Coating
Shallow metal roofs that hold water behind rooftop units or at gutters take silicone for its resistance to standing water.
Silicone coating details
Acrylic Roof Coating
Steeper metal roofs that shed rain quickly suit acrylic, which stays bright and recoats easily.
Acrylic coating details
Spray Foam Roofing
Buildings that drip on cold mornings or cost a lot to heat get foam over the panels for insulation.

Which Metal Roofs Around Bardstown Are Good Candidates?
Stiff panels, surface rust
Roofs with stiff panels, rust limited to surface bloom, and leaks that trace to screws, laps, or ridge caps make the strongest candidates. That covers many warehouses, shop buildings, church fellowship halls, farm equipment buildings, and metal-roofed retail strips. Widespread rust-through, crushed ribs, or framing that sags between purlins means those areas get new panels before coating.
Does Prep Differ For Standing Seam And R-Panel Roofs?
Yes, quite a bit
On an exposed-fastener R-panel roof every screw passes through the sheet, so fastener rows take most of the prep time. Standing seam panels hide their clips under the seam, so the work centers on seams, end splices, and trim screws. Standing seam panels also move more on their clips, and some manufacturers limit what goes on them.
Can You Coat Over A Rusty Metal Roof?
Yes, after priming
Surface rust is cleaned and primed with a rust-inhibiting primer, and that pairing is the most common metal roof restoration. Flaking scale comes off with wire brushes or grinders, while tight rust gets cleaned and treated so primer grips it. Holes where the steel is gone get a patch or a new panel section first.
Do I Need A Permit To Coat A Metal Roof In Nelson County?
Ask code enforcement
Call Nelson County Code Enforcement before work starts, since the state building department lists that office as the local inspector. Coating, foam, and panel replacement are treated differently, and foam or new panels change the roof assembly. Have the address, roof area, panel type, and planned work ready. Historic district buildings also go to the Historic Review Board.
How Often Should A Coated Metal Roof Be Walked?
Twice a year
Plan one walk in spring and one in fall, plus a look after any hailstorm or high wind. Check the end laps, ridge caps, and screw rows first, since those are the spots that opened up before the coating. Dated photos from each walk make it easy to spot a thin area spreading between visits.
