Our metal roof coating services in Altoona cover five systems, and the roof surface, slope, and drainage decide which one goes on your building.
These metal roof coating services in Altoona all start with the same inspection, then follow the system that fits the roof surface and drainage.
Ribbed and standing seam panels get screws fixed, rust treated, and laps sealed before two coats go on. This is the main service for shops and warehouses. Shops with exhaust stacks get each collar rebuilt before the field is coated.

Low-slope sections that hold water after storms take silicone over a matched primer, with the low spots and drains investigated first. Wet insulation under those spots is replaced before coating.

Pitched metal that drains quickly takes an acrylic build with fabric at the laps, scheduled for warm, dry days so each coat cures. A white topcoat also reflects summer sun off the panels.

Flat roofs that need insulation get foam sprayed over a dry deck, then a protective topcoat that keeps sunlight off the foam. Overspray is controlled around cars, walls, and rooftop intakes.

Commercial shingle sections, such as mansard faces, get coated only when the shingle maker allows it and the tabs still lie flat. Brittle or curled tabs point to reshingling instead.

Dot positions show the usual fit; adhesion tests and the inspection decide your roof.
Call us with the roof type and the problem you see, and we will tell you which inspection to start with and what it will look for.
The same steps sit under every system, with the materials and primers changing to suit the roof surface.
We walk the surface, the edges, and each curb, then test the existing finish and check the insulation for water before naming a system. The notes list every repair by location.
Screws, laps, flashings, wet insulation, and blocked drains get repaired first, since coating covers these details and makes them hard to find later. Drains and gutters are cleared so water leaves the roof before any coating starts.
Washing, rust treatment, and the primer the product calls for go on in the order that system needs, section by section. Bare steel is primed during the same shift it is cleaned.
Base and top coats go on at the rated thickness, and we gauge the build at laps, curbs, and edges before calling the roof finished. Thin spots get another pass before we move on.
A final walk covers the repairs made, the coating build at the details, and what to look at after each winter.
Cost
Price follows preparation more than product. A roof with tight screws and light rust costs less to coat than one with hundreds of failed washers, whatever system goes on. The ballpark range for coating runs about $2.50 to $4.00 per square foot, and the inspection pins down where your roof sits.
The inspection notes list each screw row and lap that needs work.
Yes. A shop with a pitched metal roof and a flat addition often takes acrylic or metal coating on the panels and silicone or foam on the flat section. Each area gets its own primer and details, and the transition between them is flashed so water crosses the joint cleanly.
Where steel is rusted through, panels are replaced as part of the job and listed separately, so the coating goes over a roof with no holes in it.
Process
Every active leak is traced and fixed first. Coating over a leak buries the evidence, so we find the screw, lap, or flashing that lets water in, repair it, and only then build the coating over that spot.
We coat in sections, starting away from doors and docks, and keep material and equipment on one side of the building. Tenants and staff get notice of which area is being washed or coated each day. Each area is coated and checked before the next one opens.
Wet board is cut out and replaced before any system goes on, since trapped water under a coating keeps damaging the deck and the new surface.
Coating Choice
Drainage decides most of it. Acrylic needs water to run off, so it suits pitched panels; silicone tolerates water that lingers, so it suits low spots. Silicone over acrylic is fine; the reverse rarely bonds. The existing surface and the next recoat count too, because only silicone bonds well over silicone.
Foam fits a flat roof that also needs insulation or has an uneven surface to build up. The deck has to be dry and firm, and the foam needs its topcoat renewed over time to protect it from sunlight. The foam thickness can also be tapered to push water toward the drains.
Halls often combine a metal or flat roof with a shingle face. Each surface gets its own system, and the joints between them are flashed so water crosses cleanly.
Start with a ballpark from your roof size, or call and walk through which system suits your building.
