Screws Backing Out of the Panels
Rubber washers dry out and crack after years of sun and cold. As panels grow and shrink with every freeze and thaw, screws loosen and each hole turns into a drip line.

As an Elkhart metal roof coating contractor, we reseal screws, laps, and rusted panels, then coat the whole roof while production keeps running below.
Elkhart metal roof coating jobs usually begin with one of these six conditions. Each one gets repaired before any coating goes on.
Rubber washers dry out and crack after years of sun and cold. As panels grow and shrink with every freeze and thaw, screws loosen and each hole turns into a drip line.
Long panel runs on plant roofs move the most at their laps. Old butyl tape shrinks away, and wind-driven rain pushes sideways under the overlap toward the purlins.
Water lingers at eaves, gutters, and cut panel edges, so corrosion starts there first. Surface rust brushes off and takes primer; a few more winters and it eats through the steel.
Lake-effect bands off Lake Michigan can reach Elkhart County. Snow piles at the low edge, melts by day, refreezes at night, and pushes water up under the lowest laps.
Plastic skylight panels craze and split, and the flashing around their curbs pulls loose. A stained ceiling tile under a skylight row is often the first sign a plant manager sees.
Factory paint breaks down into a chalky film you can wipe off with a finger. That film keeps coating from bonding, so we pressure-wash it away before any primer goes down.
Five steps, in the order they happen on an Elkhart roof. Step one sets both the scope and the price.
We walk each panel run, check screws, laps, skylights, and gutters, and cut a core wherever wet insulation looks likely. You get photos and a written scope before any price.
Lift spots, material staging, and work zones get set around shipping doors, employee parking, and shift changes. Rooftop air intakes near the spray zone get scheduled with your maintenance staff.
Loose screws come out and larger ones go in with new washers. Laps get fabric and sealant, rust gets brushed and primed, and then the whole roof is pressure-washed.
Base and finish coats go on at the thickness the system calls for, sprayed or rolled. Wet film gets measured across every section, and thin areas get another pass.
A final roof walk checks each detail against the scope. You keep the product data, the measured thickness, and photos of the work for your maintenance file.
Five systems cover the metal, low-slope, foam, and shingle roofs we coat around Elkhart. Each card shows where that system fits.

Commercial metal roof coating for exposed-fastener and standing seam roofs. Every loose screw gets replaced or capped, laps get fabric, rust gets primer, then the coating goes on in measured passes.
Commercial Metal Roof Coating detailsSilicone stands up to water that sits after rain or snowmelt, so it goes on low-slope bays, gutters, and spots beside curbs. Later recoats need silicone again, which we plan for now.

Water-based acrylic suits sloped panels that drain fast. It flexes as the steel moves, reflects summer sun, and recoats easily, but it needs a dry stretch above its minimum temperature to cure.
Acrylic Roof Coating details
Spray foam fills panel ribs and laps with one insulated layer, then takes a silicone or acrylic topcoat. It can also build slope toward drains on roofs that hold water.
Spray Foam Roofing details
Shingle coating fits commercial shingle roofs that are aged but flat and still sealed. Missing shingles get replaced and flashing gets sealed first; curled or soft roofs get a reshingle recommendation.

Three paths for an aging metal roof. Find the condition you see up top, and the dots show which path usually fits it.
| What You See On The Roof | Repair and Coat | Spot Repairs Only | Replace Panels |
|---|---|---|---|
| Loose screws and open laps across the whole roof | Usually Fits | Sometimes | Rarely |
| One or two leaks at a known skylight or gutter | Sometimes | Usually Fits | Rarely |
| Surface rust on panels that still hold a screw | Usually Fits | Sometimes | Rarely |
| Wet insulation in a few core cuts | Sometimes | Rarely | Sometimes |
| Rust holes through panels over wide areas | Rarely | Rarely | Usually Fits |
| Wet insulation across most of the roof | Rarely | Rarely | Usually Fits |
Coating changes the roof surface and the building under it. The main gain comes first, then three more owners notice.

Most metal roof leaks start at screws, laps, and curbs. Coating seals every one of them under one continuous film, so water has fewer ways in and the panels quit rusting at those spots.
A light, reflective topcoat keeps sun off the steel, so mezzanines and upper offices under the roof run cooler on July afternoons.
Nothing comes off the roof, so assembly lines, paint booths, and shipping docks keep working while the panels are coated overhead.
Once the finish wears thin years from now, the roof gets cleaned and recoated over the same base, with no tear-off and no new panels.
We coat commercial metal roofs in Elkhart, Goshen, Warsaw, Kendallville, Columbia City, and Angola.Outside these towns? Please call us or send us a message.
Manufacturing plants and storage buildings with long panel runs, often coated a section at a time so work continues inside.
Goshen metal roof coating →Industrial metal roofs crowded with exhaust vents and rooftop units, where curb flashing gets sealed before any coating.
Warsaw metal roof coating →Warehouses, light industrial shops, and farm buildings with exposed-fastener panels and washers past their service life.
Kendallville metal roof coating →Commercial and agricultural metal buildings where we check underside moisture before deciding a roof can take a coating.
Columbia City metal roof coating →Storage and light industrial roofs that carry heavy winter snow, with extra attention at eaves, gutters, and end laps.
Angola metal roof coating →Six questions Elkhart owners ask before a coating job, answered for the roofs they manage.
Coating fits when the panels and purlins are solid and the leaks trace back to screws, laps, and rust spots. Replacement fits when panels have rusted through across large areas or wet insulation runs under much of the roof. On big RV plant roofs, coating keeps panels in place over the assembly lines.
Usually, when the steel has years of structure left. A coating seals the details that leak for well under the cost of new panels and skips the tear-off. Where purlins are bent or panels are perforated across the roof, the money is better spent on replacement, and the roof walk shows which case you have.
Yes. Pole barns, farm shops, and machine sheds with exposed-fastener panels coat well when the steel is intact. We swap worn screws, seal ridge caps and end laps, prime the rust, and coat. Heavy drip from condensation inside points to ventilation or insulation, so we flag that before pricing.
Plan a recoat once the old coating chalks heavily, cracks, or peels, and before bare steel or rust spreads across large areas. A roof walk every year or two, plus one after a hail storm, shows when that point is close. Caught on time, a recoat means cleaning, spot repairs, and a fresh topcoat.
Our published ballpark for commercial metal roof coating runs about $2.50 to $4.00 per square foot, against roughly $5 to $8 for replacement. Rust treatment, the number of screws to swap, seam reinforcement, the coating system and thickness, roof height, and lift access all move the final number after the roof walk.
Lake-effect bands off Lake Michigan have reached Elkhart County, according to the National Weather Service. Repeated snow keeps panels and gutters wet and builds ice at the eaves, where meltwater backs into laps and screw holes. Sealed laps and capped fasteners under a coating shed that water better, and we check the eaves each spring.
