We coat commercial metal roofs on warehouses, shops, storage buildings, and horse barns across Lexington, Paris, and Hamburg, after an inspection of every panel run.
Most leaks on a Lexington metal roof start at a handful of details. These are the ones we find and fix before a coat of anything goes on.
Summer heat and winter cold move the panels a little every day, and that motion walks screws loose. Cracked rubber washers then let water follow the screw shank into the insulation. We replace them with oversized fasteners and seal every head.
Water backs up under the upper panel where two sheets overlap across the slope, especially on low-pitch roofs. Rust starts inside that joint long before it shows on top. End laps get cleaned, treated, and banded with reinforcing fabric.
Chalky white powder means the zinc layer is wearing off. Orange scale at fastener heads and eaves means the steel itself is corroding. Both get cleaned back to firm metal and primed before any coating touches them.
Leaves and grit hold water against the steel for weeks, so gutter interiors rust first and overflow onto the eave panels. We clear them, flush the downspouts, and seal seams and end caps, or replace sections rusted through.
Fiberglass panels yellow, turn brittle, and leak at their laps. You can replace them with new translucent sheets, coat over them, or keep them with screens so nobody steps through during the work.
Wind-driven rain pushes in under ridge caps where the foam closures have shrunk or fallen out. New closures, sealed fasteners, and reinforced cap laps close the top of the roof before the field gets coated.
Metal roof coating is our main work, and four more systems cover the roofs around it. Each card says where that system fits best.
Exposed-fastener R-panel, corrugated steel, and standing seam roofs get cleaned, rust-primed, sealed at every screw and lap, then topcoated as one surface.
Best on: warehouses, shops, self-storage, horse barns

Low-pitch metal and flat sections that hold water at end laps or behind curbs take silicone, which resists breakdown under standing water.
Best on: low-slope sections, box gutters, ponding laps

Shingle Roof Coating in LexingtonCoating changes the details that leak. Here is the same roof before and after the work, part by part.
Start with a ballpark range for coating your metal roof.

A handful of bad sheets is common. They get swapped first, and the whole roof is coated afterward.
Five steps, in this order, on every roof we coat in Lexington.
We walk every panel run, photograph fasteners, laps, skylights, ridge caps, and gutters, and look up from inside where stains show. The findings sort the roof into coat, restore, re-panel, or replace.
Pressure washing takes off chalk, dirt, and white rust. Red rust at screws and eaves is wire-brushed back to tight metal, and the panels dry fully before primer goes on.
Loose screws come out for oversized replacements with new washers. Side laps and end laps get fabric or seam tape set into a base coat, with wider bands where water backs up.
Base and top coats go on with spray rigs and rollers, built up thicker at fasteners, curbs, and ridge caps, while intakes on nearby rooftop units stay shut.
After the topcoat cures, the roof gets a final walk with you to point out the reinforced laps and sealed details, and you keep the photos for your records.
Warehouses, shops, horse barns, and retail centers in these towns are where we coat metal roofs most. Outside them? Call us or send us a message.
R-panel warehouses and storage buildings across Fayette County, plus barns and arenas on the farmland outside the urban area.
Multi-tenant retail and office roofs, metal canopies, and standing seam accent roofs facing the parking lots.
Downtown storefronts and Bourbon County machine sheds, many with service drops and conduit crossing the panels.
Short answers to what owners ask first. The full list is on our metal roof coating FAQ.
Yes, once the screws and laps are repaired first. Topcoat brushed over a loose screw or an open lap splits as soon as the panels move. We tighten or replace fasteners, cap each head, and set fabric into the laps, then coat the whole roof, including curbs, pipe boots, and ridge caps.
It matters most where water lingers. NWS Louisville logged 49.98 inches at Lexington in 2024, close to normal, and every one of those rains crosses the eave and sits at low end laps. We add material at those spots and ask that gutters and downspouts stay clear.
Prep, more than paint. Fastener count, rust depth, the length of laps that need fabric, and the number of skylights and penetrations drive most of the price, along with the coating system and how hard the roof is to reach. A measured roof walk comes before any firm number.
LFUCG's Division of Building Inspection covers all of Fayette County, so a downtown office and a shop near the county line file with the same office. Tell them whether panels, purlins, or skylights come out, and whether foam or new edge metal is planned.
Every panel run. Close-up photos cover fasteners, laps, seams, skylights, ridge caps, and gutters, and we check rust depth and soft spots from the roof and from inside. On a roof with an older coating, adhesion and chalking get tested too. You see the photos before any choice is made.
Often, after testing. An old coating that still grips the panels gets washed, scuffed where glossy, and patched where it peels. A small adhesion test with the new product on your actual roof shows whether it bonds; where it fails, the loose coating comes off first.
