As a Kearney commercial metal roof coating contractor, we tighten fasteners, treat rust, reinforce laps, and coat steel roofs on shops, mills, and warehouses.

Fit Check
Kearney commercial metal roof coating works on steel that still holds a screw. Compare your roof with both cards before you plan the job.
Roof Conditions
These are the conditions that bring most Kearney metal building owners to a coating, listed by where they show up on the roof.
Hundreds of exposed screws hold a typical shop roof down. As washers dry out and screws loosen, each row turns into a line of pinholes that leak in heavy spring rain.
Panels move with every temperature swing, and the overlap between them opens a little each season. Wind-driven rain finds those gaps quickly.
Bottom panel edges at the eaves stay wet longest. Rust starts there, then creeps up under the paint toward the first purlin.
Rooftop units and exhaust fans on mills and plants sit in flashing that vibrates. Caulk along those curbs splits and lets water run along the purlins.
Internal gutters between building sections fill with dust and leaves. Standing water there eats through the gutter liner before anyone sees it.
Coating Options
Three coating approaches fit most metal buildings around Kearney. The roof's slope, drainage, and insulation needs decide which one we recommend.
Screws are capped, laps are taped, and the whole roof gets a base and top coat. This is the most common job on Kearney shops and storage buildings.
Low gutters, valleys, and flat transitions that hold water take silicone, which stays sealed under standing water. Later recoats must be silicone too.
Foam fills the panel ribs and covers every screw in one layer, then gets a protective topcoat. It suits buildings that run cold in winter.
Benefits
A restored metal roof keeps the building working and puts off the cost and mess of new panels.
Restoration keeps every existing panel, purlin, and trim piece in place. The coating seals the details, and the steel underneath stays protected from new rust as long as the coating holds its thickness.
Light coating colors reflect more sun than faded paint, so the steel over offices and break rooms heats up less on summer afternoons.
Each fastener head gets a cap of coating material, which seals the hole the old washer used to cover.
Owners stop hunting new leaks after each storm, because the laps and screws are sealed together instead of one at a time.

Process
The order matters on metal. Skipping a step at the screws or laps is where most coating failures start.
Our first visit covers every panel run, the gutters, and each curb. We probe suspect areas for wet insulation and press on rust spots to find steel that has thinned.
A pressure washer takes off chalked paint, bird droppings, and mill dust. The roof dries before primer goes on, so this step starts early in the day.
Wire brushes and grinders remove loose scale, then a rust-inhibiting primer covers the bare spots. Holed panels get patched with matching metal or replaced.
Loose screws are tightened, stripped ones are swapped for larger ones, and every head is sealed. Laps get reinforcing fabric bedded in base coat.
Spraying the base and top coats over the full roof at the specified thickness finishes the system, with wet film checks along the way.

Answers about prep, price, and weather for metal panel roofs on Kearney commercial buildings.
Coating jobs here plan at about $2.50 to $4 per square foot, the same range the estimate form uses. A full panel replacement plans at about $5 to $8 for comparison. The final number comes after we count fasteners, measure lap runs, and see how much rust treatment the steel needs.
Prep is the difference. A roof with heavy scale, backed-out screws, and open end laps takes more cleaning, primer, and seam fabric than a roof with light surface rust. High eaves, tight lift access, an extra coat, or wet insulation that has to be cut out also add labor, so the inspection narrows the range.
Fastener work comes first: loose screws are tightened, stripped ones are replaced with oversized screws, and every head is sealed. Then the panels are washed, rust is treated, and primer goes on where the product calls for it. Laps get fabric or seam tape in base coat before the finish coats cover the whole roof.
Loose scale is removed with wire brushing or grinding, and a rust-inhibiting primer goes over the cleaned steel. Light surface rust that the primer bonds to can stay. Steel with holes or flaking layers is patched with matching metal or replaced, because coating over active scale lets the rust lift the coating later.
It is a full renewal of the existing roof without removing it: inspection, cleaning, fastener and seam repairs, rust treatment, and a fluid-applied coating system. On mills, the cleaning step also deals with grain dust and vent discharge. The plant keeps running, since the roof stays on the building the whole time.
Hail dents panels and can bruise or puncture the coating, while repeated freezing and thawing works at seams and screws. A coating applied at full thickness takes small impacts better than a thin one. After a hail storm we walk the roof, check seams, caps, and dents, and patch small damage before water reaches the steel.
