As an Alton metal roof coating contractor, we coat older steel shop roofs and give skylight panels, roof vents, and chalked paint their own prep.
Alton metal roof coating work often lands on shop buildings that have seen decades of weather. Chalked paint, surface rust, and loose screws are normal at that age.
The details are what take extra care. Fiberglass skylight panels, ridge vents, and wall fans all break the roof surface, and each one gets its own seal before the field coat.
Age shows up in the details on these roofs.
Coating an older shop roof buys years of service without new panels.
New or sealed skylight panels keep natural light in the shop while stopping drips.
Primer and coating cover chalk and rust so the old panels stay in service.
A coated roof can be cleaned and recoated later, which costs less than new steel.
Fabric-flashed vent bases keep water out at the spots that leak first on older shop roofs.
Older roofs here usually need one of these systems.
Most older steel shop roofs get the full metal coating build with fabric at laps and vents.

We check every skylight, vent, and fastener row, test chalk and rust, and take moisture readings near old leaks.
Cracked light panels and rusted-through steel get swapped for new pieces with matching rib profiles, fastened with new washered screws.
A detergent wash removes chalk, wire wheels take off loose rust, and primer goes on bare metal once a tape test shows the surface is clean.
Vent curbs get fabric and a detail coat, worn screws get replaced a size up, and every head gets sealant.
The coating goes on to spec thickness across the panels and over the detailed vents and skylights, checked with a wet-mil gauge as it goes.

Kingsley metal roof coatingAlton owners with older shops ask these most.
Often, yes, when the panels are still firm. Years of weather leave chalked paint, surface rust, and loose screws, and prep work handles all three. Panels with holes, crushed ribs, or rust at the laps get replaced first, and skylights and vents get their own detail before the field coat.
Coating plans at about $2.50 to $4.00 per square foot. Older roofs land higher when they need new skylight panels, many new screws, or replaced steel at the laps. A roof walk counts those items so the estimate reflects the real roof.
Rarely. Coating happens on the roof, and skylight swaps take only short openings, which we time around your work. Anything under an open skylight gets covered first.
Yes. Alton is one of the Siouxland towns where we coat commercial metal roofs. Call (402) 258-4527 to book a roof walk, or get a ballpark estimate from your roof size first.
Only when they are flat, uncracked, and the shop has no further use for the daylight. Otherwise we replace them with new panels in a matching profile, because coating over a brittle panel leaves a weak spot in the roof.
Working turbine vents are kept, cleaned, and flashed with fabric at the base. Seized or rusted-out vents get replaced, or removed and covered with a new panel section when the shop has no further need for the airflow.
Chalk is loose, powdered paint sitting on the panel surface. Coating applied over it bonds to the powder instead of the steel and can peel. A detergent wash and rinse remove it, and a tape test confirms the surface is clean.
