Industrial roofing contractor for Iowa, South Dakota and the Upper Midwest
A-1 Roofing is a commercial and industrial roofing company based in Platte, South Dakota, working on commercial roofs since 1985. We serve warehouses, manufacturing plants, food processing buildings and cold storage across Iowa, South Dakota, North Dakota, Minnesota, Nebraska and eastern Wyoming. The roof gets inspected first. If the deck is sound, we restore it in place with a coating or spray foam system. If it is not, we repair or reroof it.
What fails, and what we do about it
Warehouses and distribution centers
Seams open across a large roof field, water ponds at the drains, and leaks land on racking and stock.
A moisture survey, then seam and drain repairs and a coating over the existing single-ply or metal roof.
Manufacturing plants and factories
Curbs, penetrations and rooftop equipment multiply the leak points, and a leak over a line can stop production.
Every detail repaired and reinforced, then the field restored with the coating or foam system matched to the substrate.
Food processing and cold storage
Exhaust residue wears at the membrane, and wet insulation over a cold room stops doing its job.
A survey to find the wet insulation, removal where needed, then a coating or foam system sized to the building.
Metal and pre-engineered buildings
Fastener gaskets age, lapped seams work loose and panel edges rust.
Clean, prime and reset fasteners, then coat the panels as one continuous membrane.
Older built-up roofs
The flood coat cracks, plies separate and water tracks between them.
A spray foam conversion when the survey shows the roof is dry enough to keep.
Industrial roofing services
Emergency repair stops an active leak and protects the building. Routine repair fixes known problems such as failed seams, flashings and drains. Contract maintenance puts the roof on a planned inspection cycle and documents it to keep it under warranty.
For larger work, restoration and coatings renew a sound roof in place, and reroofing replaces one that cannot be saved. A free on-site assessment shows which of these the building needs.
What makes an industrial roof a different job
Industrial roofs are large and low-slope, with exhaust, curbs and rooftop units cutting through them and service crews walking across them. Water can run a long way along the deck before it shows up inside, and it may land on stock, machinery or electrical panels when it does. Finding the real entry point comes before any repair.
Why industrial roof restoration comes first
A tear-off opens the roof over stock, equipment and people. Restoration keeps the existing roof in place, so the building stays closed and keeps working below.
It only works on a sound roof. A moisture survey and adhesion test decide that before any price is given. Single-ply, metal, modified bitumen and existing foam roofs usually take a coating. Built-up roofs usually convert to spray foam.
On a coated roof, the crew washes the surface, makes repairs, primes where needed and details the seams and penetrations before the coating goes on. The finished system carries a 10, 15 or 20-year warranty based on the thickness applied.
When industrial reroofing is the right call
Widespread wet insulation, failed adhesion or structural rust-through rule restoration out. In that case we repair what can be repaired and quote the replacement, because a coating over a failed roof only hides the problem for a while. Slope, drainage, exhaust and foot traffic all go into the choice of new system.
Industrial roofing in Iowa
Iowa's food processing plants have some of the largest single-building low-slope roofs in the Midwest, and the state's humidity and freeze-thaw cycles are hard on seams and flashings. A leak over a processing room can reach product, so we check for moisture before anything else.
Our industrial roofers serve Des Moines, Cedar Rapids, Sioux City, Waterloo, Council Bluffs, Marshalltown, Ottumwa and the rest of the state. We are based in Platte, South Dakota, and Iowa is one of our six service states, so ask about timing for your location when you call.
Industrial roofing contractors in South Dakota
South Dakota is home. A-1 serves warehouses, plants and processing buildings in Sioux Falls, Rapid City, Aberdeen and across the state. Hail, high wind and freeze-thaw do most of the damage here, so seams, flashings and roof edges get a close look during the inspection.
What we ask before quoting
We start with the roof type, its age and any warranty still in force. Then we ask what sits under the leak, what hours the building runs and when the roof can be reached. We also want to know what is on the roof, including exhaust, curbs and air intakes, and whether you want to add insulation or only stop the water.

Common questions
- What does an industrial roofing contractor do?
- An industrial roofing contractor repairs, restores, maintains and replaces roofs on warehouses, plants and processing buildings. A-1 leads with restoration, coatings and repair, and quotes a reroof when the roof cannot be saved.
- Is commercial and industrial roofing the same work?
- The roof systems are largely the same, including TPO, EPDM, PVC, metal, built-up and modified bitumen. Industrial buildings add larger roofs, more rooftop equipment and operations that have to keep running below.
- What kinds of industrial buildings do you work on?
- Warehouses, distribution centers, manufacturing plants, food processing buildings, cold storage and metal industrial buildings.
- Can an industrial roof be restored instead of replaced?
- Often, yes, when the deck is sound and the insulation is dry. A moisture survey and adhesion test confirm that first. If the roof does not qualify, we say so and quote the repair or replacement instead.
- What does an industrial roof replacement cost?
- It depends on the roof's size, its condition and how it can be reached. Industry estimates put silicone coating restoration at about $2 to $5 per square foot (West Roofing Systems) and a TPO tear-off and reroof at $7.75 to $12.00 (Commercial Roof Guide, March 2026). We quote from the inspection, whether the building is in Minneapolis, Des Moines or Sioux Falls.
- Can the building keep running during the work?
- Restoration happens above an occupied, operating building, and with no tear-off the roof stays closed. We plan access and staging around the building's schedule before work starts. A reroof takes more planning, and we go through that with you section by section.
- Do you handle leak repair on industrial roofs?
- Yes. A-1 provides emergency response for active leaks, routine repairs and contract maintenance across all membrane types. Call with an active leak and we will give you a real response window for your location.
- What warranty comes with an industrial roof restoration?
- Coating and foam systems carry 10, 15 and 20-year warranties when applied at the required thickness. The term is set by the thickness, so it is part of the scope we quote.
- Do you work on industrial roofs in Iowa?
- Yes. A-1 works across Iowa, including Des Moines, Cedar Rapids, Sioux City, Marshalltown and Ottumwa, along with South Dakota, North Dakota, Minnesota, Nebraska and eastern Wyoming.
