As a Sioux City metal roof coating contractor, we clean, prime, and coat steel roofs on shops, plants, and warehouses. Every job starts with a roof walk.
Most Sioux City metal roof coating jobs start with one of these six conditions. Each card names the cause, what you see, and what it tells us about the roof.
Coating keeps the existing steel in place, so the building stays open while the roof gets a new surface.
Crews work from the roof surface, so loading docks, offices, and production floors below keep running. Ladder and lift spots go away from truck lanes and entrances.
Old panels stay on the building instead of going to the landfill. Fasteners, laps, and curbs get repaired, and one continuous film seals the whole surface.
A white coating reflects summer sun that bare or rusted steel soaks up, which keeps the deck and the space under it cooler on hot Siouxland afternoons.
A coating rated for its thickness can be cleaned and recoated near the end of its term, so the steel underneath stays covered for another round.
Five systems cover the roofs we see across Siouxland. Pick the one that matches your roof, or let the roof walk decide.
Fastened LapsExposed-fastener and standing-seam steel roofs that leak at laps and screws. We treat rust, seal every fastener head, and coat the panels in place from ridge to eave.
Low-Slope LapsSilicone handles water that sits on low-slope roofs for days, so it fits older built-up, metal, and single-ply roofs where drains run slow. Later recoats stay silicone.
Sloped PanelsAcrylic suits sloped panel roofs that shed water quickly. It bonds to primed steel, stays flexible through heat and cold, and goes on during warm, dry stretches of the season.
Sprayed FoamPolyurethane foam sprays on as one continuous layer that covers seams and fasteners and adds insulation. A protective coating goes over the foam to shield it from sunlight.
Granule SurfaceShingle coatings bond to the granule surface on pitched commercial roofs where the shingles still lie flat. Curled tabs and soft decking point to repair or replacement instead.
Call and tell us where the water shows up inside. We set up a roof walk, find the source, and explain what coating or repair the panels need.
(402) 258-4527Call UsEvery roof goes through the same five questions, in this order. The answers decide whether we coat, repair first, or recommend replacement.
We walk every section, check fastener lines and laps, and take moisture readings or core cuts where insulation could be wet. Photos of each problem go into your estimate.
Solid steel with surface rust, open seams, or loose screws qualifies. Rust-through across large areas, crushed ribs, or soaked insulation move that section to repair or replacement first.
Slope and drainage decide most of it. Sloped panels that shed water take acrylic or silicone, low spots that hold water take silicone, and roofs that need insulation get foam.
Pressure washing, rust removal, primer, fastener work, and fabric at seams and curbs. Prep usually takes more days than the coating itself, so it shapes the schedule.
Coating plans around $2.50 to $4.00 per square foot and replacement around $5 to $8. We show how the recoat path compares with a full tear-off for your roof.
Most roofs fall clearly into one column once the inspection is done. Here is how we sort them.
| Roof Detail | Coat It | Repair First | Replace It |
|---|---|---|---|
| Panel steel | Surface rust, chalked paint, light pitting | A few rust-through holes or cracked laps | Perforation across many panels |
| Fasteners | Some loose or missing screws | Stripped holes along whole purlin lines | Purlins or clips that no longer hold |
| Insulation | Dry readings across the roof | Wet pockets under a few panels | Soaked insulation over large areas |
| Drainage | Water runs off within a day | Clogged gutters or one sagging bay | Framing sag that traps water roof-wide |
| Curbs and vents | Sealant that is cracked but attached | Rusted curbs or failed pipe boots | Equipment layout changing with a reroof |
Is your building outside these towns? Call us or send us a message. We coat commercial metal roofs in Sioux City, Sergeant Bluff, Onawa, Moville, Kingsley, and Alton.
Shop and warehouse roofs here often need coating staged around loading doors and steady truck traffic.
Sergeant Bluff metal roof coatingFarm supply buildings, steel shops, and storage sheds with rusted laps make up most of the coating work we plan here.
Onawa metal roof coatingCoating jobs here are timed to dry spells, with dew and overnight lows watched closely through spring and fall.
Moville metal roof coatingMoisture readings come first on these roofs, so wet insulation gets cut out before any coating is applied.
Kingsley metal roof coatingOlder shop roofs with chalked paint, skylight panels, and roof vents get each detail sealed before the field coat.
Alton metal roof coatingShort answers to what owners ask most on a first roof walk. The full list is in our metal roof coating FAQ.
Yes, when the rust sits on the surface and the steel underneath is still firm. We remove loose scale, prime the bare spots, and coat over it. Holes where rust has eaten through get a new section of panel first. If perforation shows up across many panels, we price replacement for those sections instead.
Often it is, because a warehouse roof is usually a large, simple field of steel with long runs of laps and fasteners. Coating it keeps the racks, docks, and offices below in use. We check rooftop units, drains, and the insulation first, since wet insulation or a sagging bay has to be fixed before coating.
For planning, coating runs about $2.50 to $4.00 per square foot and replacement about $5 to $8. Where your roof lands depends on how much rust and fastener work it needs, the total square footage, how hard the roof is to reach, and how many coats the system calls for.
Coating makers rate their systems by the thickness applied, commonly about 10 to 20 years. Hail, foot traffic around equipment, and water that sits on low spots shorten that span. A check each spring and after big storms keeps small tears from spreading, and an intact coating can take another coat near the end of its term.
