End LapsRed Rust At End Laps
Water lingers where one panel overlaps the next, so rust starts there first. We grind it back, prime it, and set fabric before coating.
We do commercial metal roof coating in Sturgis, where damp ground near the Ohio River keeps laps, washers, and gutters wet longer than on higher land.


Sturgis sits close to the Ohio River, and buildings on low ground there stay damp longer after rain and fog. Longer wet time speeds rust at end laps, screw washers, and gutter bottoms.
Our Sturgis roof walks focus on the spots where water lingers. North-facing slopes collect mildew and algae, downspouts clog and back water onto the eave, and gutter hangers rust loose.
These four conditions show up most on Sturgis metal buildings near the river.

GuttersA blocked downspout backs water into the gutter and over the eave edge. Clearing it protects the roof edge and the foundation below.
MildewShaded slopes stay wet into the afternoon and grow mildew and algae. Washing removes them so primer and coatings can grip.
InsideLeaks near exterior walls often trace to rusted gutter hangers and outlets. Those get replaced before the field coat goes on.
On a damp property, a sealed roof surface slows the rust that wet laps and gutters cause.

Coating closes the end laps, screw heads, and gutter seams where Sturgis roofs stay wet longest. Steel that is still firm keeps its strength under the coat instead of rusting through.
Catching rust at the laps while the panels are still firm keeps the work to prep and coating, which costs less than new metal.
Shops and offices in Sturgis stay open while crews work on the roof above, with ladder access placed away from the entrances.
Once coated, the roof needs washing, gutter clearing, and touch-ups rather than screw-by-screw repairs every year.
Three coatings cover most Sturgis metal buildings, chosen by how fast each roof section drains.

Exposed-fastener roofs get new washers, sealed laps, and primed rust under a full coat.

Call UsOn damp properties the cleaning and drying stages take longer. Here is the order the work follows.
We walk the roof and the eaves, checking end laps, washers, gutter hangers, outlets, and downspouts, and note where rooftop units need electrical work. Damp spots get a moisture check before anything else.

Downspouts and outlets are cleared, and mildew and algae are washed off the panels. North slopes get more drying time before primer.

Rusted gutter hangers and outlets are replaced, end laps are ground back and primed, and loose screws are swapped for larger ones.
Coatings go on after dew clears and the panels test dry. We measure thickness and check that gutters drain freely before the job is closed.
Along with Sturgis, we coat commercial metal and low-slope roofs in Henderson and these four towns.

Answers on river damp, rooftop units, and inspections for Sturgis building owners.
Watch for longer wet time. Buildings on low ground near the river keep panels and gutters damp, which speeds rust at laps, washers, and gutter bottoms. Check north slopes for mildew, end laps for red rust, downspouts for clogs, and gutter hangers for rust.
It can push start times back. Panels stay wet with fog and dew until the sun clears them, and coating goes on dry metal only. We test panel dryness at the building and start later in the morning when river fog lingers.
Start with Sturgis city hall. The state Union County sheet sends local electrical inspection questions to the city office where the work happens or to the County Judge Executive’s office in Morganfield. Unit work comes up when curbs are rusted, conduit crosses the panels, or a unit is replaced during the coating.
If the unit is due soon, yes. Swapping it first means the new curb gets flashed and coated once, instead of cutting into a fresh coating later. Units that stay get their curbs sealed, corners reinforced, and conduit supports resealed.
Building permits in Union County fall to the state building inspector, because the state contact sheet lists no local one. Coating-only scopes with no structural change are the simplest to clear; re-panel work or structural repairs are the items to raise.
Flooding at ground level is a site issue, separate from the roof. The roof’s part is gutters and downspouts that move water off the building and away from the walls, so we make sure they drain before coating.
