As a Kearney metal roof coating contractor, we clean, repair, and coat exposed-fastener and standing-seam metal roofs on shops, warehouses, and plants in and around Kearney.
Moisture check before any coating
Fasteners and laps sealed first
Mils measured during application
Buildings stay open during work
Coat Or Replace
Kearney metal roof coating fits steel that still holds a screw. Replacement fits panels with rust holes or a soaked deck. Here is how the two compare on one roof.
Work Sequence
Six steps take a leaking metal roof to a coated one, and the building below keeps working the whole time.
Walking every panel run, we probe for wet insulation, count backed-out screws, and mark rust that has thinned the steel. You see which sections qualify for coating and which need new panels first.
Pressure washing strips chalk, dirt, and grain dust so the primer can grip bare paint and galvanizing. Panels then dry fully, which often takes most of a spring day.
Loose scale comes off with wire brushes or a grinder. A rust-inhibiting primer goes on wherever the coating maker calls for one, including cut edges at the eaves.
Every screw gets tightened or swapped for an oversized fastener, then capped. Side laps and end laps get fabric or seam tape set in base coat.
Base and top coats go on by spray or roller at the specified thickness. A wet film gauge checks mils as each section is finished.
Before the crew leaves, a final walk checks each seam, fastener row, gutter, and curb, and any thin spot gets a touch-up coat.
Coating Systems
Each system fits a different roof. The table lines them up by the panel or surface underneath, how they handle standing water, and how they get recoated later.
| System | Best Substrate | Ponding Tolerance | Typical Use | Recoat Path |
|---|---|---|---|---|
| Commercial Metal Roof Coating | Exposed-fastener and standing-seam steel panels | Best on sloped panels that drain | Shops, warehouses, and mills | Recoat with the same chemistry |
| Silicone Roof Coating | Metal, single-ply, and foam surfaces | Handles water that sits in low spots | Low-slope sections and gutters that hold water | Silicone over silicone only |
| Acrylic Roof Coating | Primed metal on sloped panels | Softens under standing water | Well-drained metal buildings | Clean and recoat with acrylic |
| Spray Foam Roofing | Metal and built-up roofs that need insulation | Foam can be shaped to drain | Buildings that need added R-value | New topcoat over the foam |
| Shingle Roof Coating | Asphalt shingles lying flat over a firm deck | Steep slopes shed water fast | Offices, clinics, churches, and retail | Touch-up coats on worn spots |
Call and tell us where the drip shows up inside. We can walk you through what to check on the roof before an inspection.
Why Coat
Coating keeps the existing steel panels in service and seals the details that leak first.
Coating goes on over the panels you already have, so the roof is never open to weather. Mills, shops, and warehouses keep loading and storing while work moves across the roof one section at a time.
White and light coatings reflect more summer sun than weathered galvanized steel, which keeps panel temperatures down over offices and storage rooms.
Sealed screw heads and reinforced laps close the openings where most metal roofs start leaking, across the whole roof at once.
Once the coating wears, the roof gets cleaned and recoated instead of torn off, provided it was kept at its specified thickness.
Roof Zones
Leaks on a metal roof rarely start in the middle of a panel. These five zones are where an inspection looks first.
Gutters packed with leaves and grain dust keep the panel ends wet. Rust starts at the cut edge of the bottom panel and climbs the lap toward the first fastener row.
Side laps open as panels expand on hot afternoons and shrink on cold nights. End laps pull apart once the sealant strip dries out and cracks.
Screws back out over the years, and the rubber washers under their heads harden and split. Each one becomes a small hole that drips during heavy rain.
Exhaust fans, rooftop units, and pipe boots sit in flashing that was caulked once and left alone. Hail and foot traffic crack that caulk first.
Ridge caps and rake trim catch wind-driven rain. Loose closures and missing screws along the ridge let snowmelt drip onto stored goods below.
Service Area
Shops, implement buildings, and storage buildings in these towns are where we coat metal roofs most. Outside them? Call us or send us a message.
Holdrege jobs often cover a storefront roof, a back warehouse, and a canopy, so each section is measured and priced on its own.
Minden implement and storage buildings with exposed screws usually leak at the fasteners and end laps long before the panels give out.
In Gibbon we stage wash days and spray days around loading doors and parking so the business keeps running below.
Ravenna roofs near grain handling collect dust that has to come off before any primer can grip the panels.
After a hail storm, Shelton roofs get a walk that checks dented panels, cracked fastener caps, and bruised coating.
Owner Questions
Short answers to what owners ask before they schedule a coating. The full list is on our FAQ page.
Service life comes down to film thickness, prep, and upkeep. Coating makers commonly rate their metal roof systems for roughly 10 to 20 years at the specified mils. On Kearney roofs, thin spots at gutters, hail strikes, and foot traffic around rooftop units wear a coating fastest, so a yearly walk with quick touch-ups adds the most years.
Coating wins when the steel is still solid and the leaks trace back to screws, laps, and flashing. Replacement makes more sense once panels have rusted through, the deck sags, or probes find soaked insulation over large areas. We check fasteners and probe the roof before recommending either one.
For a warehouse or shop that leaks at seams and screws, it usually is, because one coating system closes those openings and adds a reflective surface. It stops making sense once rust has eaten holes through panels or the framing is damaged. An inspection sorts the roof into areas that qualify and areas that need panel work.
Late spring through early fall works best around Kearney, when panels stay dry and air temperatures stay above what the product sheet requires during cure. Acrylic needs the warmest, driest stretch. Silicone handles cooler days but still needs dry steel, so morning dew pushes start times later in spring and fall.
Plan on about $2.50 to $4 per square foot for coating, compared with about $5 to $8 for a full replacement. Where a roof lands comes down to its size, rust depth, how many seams and screws need work, lift access, the number of coats, and any wet insulation to cut out.
