Metal Roof Coating
Rust treatment, fastener work, lap sealing, and a coating system for R-panel, standing seam, and corrugated roofs.
Fits: Steel that still holds a screw

Louisville Commercial Roof Coating Services
Our commercial roof coating services in Louisville cover five systems: metal, silicone, acrylic, spray foam, and shingle coatings, matched to roof type, slope, and the building underneath.

Our Commercial Roof Coating Services In Louisville
Each system fits a different roof. The fit line under each card tells you where it belongs.
Silicone Roof Coating
A coating that holds up under standing water on low-slope metal, flat roofs, and box gutters.
Fits: Roofs and gutters where water sits
See Silicone Roof Coating
Acrylic Roof Coating
A bright white, water-based coating for sloped roofs that drain fast, applied in dry weather.
Fits: Sloped metal with good drainage
See Acrylic Roof Coating
Spray Foam Roofing
Closed-cell foam that adds insulation and fills panel ribs, finished with a protective coating.
Fits: Heated or cooled space under metal
See Spray Foam Roofing
Shingle Roof Coating
Coating for flat, attached asphalt shingles on commercial mansards and steep sections, where the shingle maker allows it.
Fits: Shingles still in fair shape

Metal Roof Coating covers the prep and rust work on steel; the topcoat on a metal roof is often silicone or acrylic.
Which System Does Your Roof Need?
Send the roof type, the slope, and what the space underneath is used for. The roof walk settles the system before anyone prices it.
One Process For Every System
The coating changes from roof to roof. The order of work stays the same on all five systems.
- INSPECT
Step 1: Inspect Your Roof
We walk the roof, check underneath from inside, take moisture readings on flat sections, and test adhesion on painted or coated surfaces before naming a system.
- CHOOSE
Step 2: Match The System
Slope, standing water, insulation needs, and the existing surface decide between metal, silicone, acrylic, foam, or shingle coating, and sometimes two systems on one building.
- PREP
Step 3: Clean And Repair
Washing, rust treatment, fastener work, and sealer with fabric at laps, curbs, and flashing come before any field coat, whatever the system.
- APPLY
Step 4: Apply To The Data Sheet
Each product goes on at the thickness its maker lists, with rooftop intakes, skylights, and parked vehicles protected from drift.
- CHECK
Step 5: Check And Hand Over
Thickness gets checked, missed spots are touched up, and you receive photos of the roof before and during the work.
Choosing A Coating System
Questions about which system goes where, answered for commercial roofs around Louisville.
Question about your own roof?
Call UsWhich commercial metal roofs are good candidates for coating?
Roofs with solid panels, surface rust, and leaks at seams or fasteners are the strongest candidates. Rust holes, sagging purlins, or wet insulation need repair or replacement first.
Around Jefferson County that covers warehouses, shops, farm buildings used for business, churches, and older retail. Standing seam coats well too, with prep focused on end laps, clips, and penetrations.
Silicone, acrylic, or urethane: which coating fits a metal roof?
Silicone fits metal roofs with flat spots and ponding, acrylic fits sloped roofs that shed water fast, and urethane fits roofs with heavy foot traffic or impact. Silicone holds dirt and needs silicone for recoats, acrylic needs warm, dry weather, and urethane carries more odor. On rusty steel, a rust-inhibiting primer goes under any of them.
Should a metal roof be coated, restored, re-paneled, or replaced?
Solid steel with surface rust gets coated, and widespread rust-through or deck damage calls for replacement. Restoration sits between: coating plus heavier repairs like reinforced laps and patched panels. Re-paneling swaps only the holed panels. A rust and moisture survey sorts each section, and one building often lands in two categories.
Can one building get two coating systems?
Yes, and it happens often. A strip center might have sloped metal in front that takes acrylic and a flat rear roof that holds water and gets silicone. Each section gets its own prep and product, and the transition between them is flashed and sealed so water stays out where the two roofs meet.
Do you coat commercial roofs other than metal?
Yes. Silicone and spray foam go on flat built-up and single-ply roofs once a moisture survey shows dry insulation, and shingle coatings go on qualifying commercial shingle sections. Metal is still the roof we coat most, so most jobs include some steel prep even when the building has mixed roof types.
