Pinholes Along The Laps
- You See
- Pinpoints of daylight at the bottom edge of a lap when you look up from inside.
- What It Means
- A few holes mean patches or new panels in spots, then coating. Holes along most laps push the job toward replacement.
We do Elkton metal roof coating on commercial shops, and the first question on an older roof is whether enough solid steel is left to coat.


Coating pays off when most of the panels are still solid steel and the framing under them is dry and straight. Then you pay for prep and coating instead of tear-off, disposal, new panels, and an open roof over your equipment.
Replacement wins when rust-through is widespread or purlins sag. The middle path is re-paneling the worst sections and coating the whole roof afterward. The evidence comes from the roof: how many panels flex underfoot, how many laps show rust holes, and whether ceiling stains follow seams or framing.
These conditions move an older Todd County roof between coating, re-paneling, and replacement.
When the panel count favors coating, an Elkton owner gets these over a tear-off.
Prep and coating replace the cost of removing panels, hauling them away, and buying new steel, when most of the roof is still solid.
Solid panels stay on the building, so only the worst sections leave as scrap if you take the re-panel-and-coat path.
Your equipment and stock never sit under an open roof, since coating happens on top of panels that stay fastened down.
Reinforced lap details close the overlaps where rust holes start, which slows the decline that pushes older roofs toward replacement.
Once the panel count is done, one of these three paths fits most Elkton shop and storage roofs.

Loose screws, open laps, and red rust at the laps get repaired, then the whole roof is coated. This is the common answer for older roofs with firm steel.
Metal roof coating and restorationShop additions with a low pitch hold water at gutters and behind curbs. Silicone handles those wet areas while the steeper main roof takes the coating that fits it.

An uninsulated Elkton shop with mostly solid panels can take spray foam over the old steel instead of a tear-off, adding insulation and a new surface in one job.

Call UsFour steps that start with the coat-or-replace decision.

We walk every run, mark panels that flex, tally rust holes at the laps, and trace inside stains to seams or framing. Overhead service drops near the eave go on the plan too.

You get a marked roof plan showing which panels to keep, patch, or replace, and whether framing needs repair. Coating only goes ahead on a roof with enough solid steel.

Rusted-through panels come off and matching panels go on, screws are tightened or upsized, and lifts are parked where they stay clear of overhead lines.

Rust spots get primer, laps and curbs get fabric, and the field coat goes on at the specified thickness, joining new and original panels under one surface.
Need a roof coated outside Elkton? Call us or send us a message. We also work in Hopkinsville and five more towns across the Pennyrile.

Distribution and shop buildings in Hopkinsville where long panel runs carry many end laps.
Storage rows kept open during coating, with spray days set around customer traffic.
Marine shops near the lake where condensation rust is checked from inside.
Machine sheds where nailed panels are refastened with screws for wood purlins.
Buildings repaired since 2021 where old and new steel meet at reinforced laps.
Farm-supply roofs where bird droppings and grain residue come off before primer.
Answers for Todd County owners weighing a coating against new panels.
When most panels are still solid steel and the framing is dry and straight. You then pay for prep and coating instead of tear-off, disposal, new panels, and the disruption of an open roof.
Widespread rust-through, sagging purlins, or a building that needs a new structure anyway make replacement the better spend, and re-paneling the worst sections before coating sits in between.
There is no fixed number; the pattern matters more. A handful of rusted-through panels scattered across a roof get replaced and the roof is coated. When holes show at most laps along whole runs, or panels flex underfoot across large areas, the steel is past saving and replacement is the honest call.
Start with the Todd County judge-executive’s office or Elkton city hall to confirm current practice, then contact the state building inspector, since the Kentucky DHBC sheet for Todd County lists no building inspector for Elkton.
Ask about recoating panels in place, replacing rusted ridge caps or gutters, and adding weight with spray foam, and keep the answers with your roof inspection notes.
Guthrie follows a different path. Both towns sit in Todd County, but the City of Guthrie has its own local building inspector, while Elkton owners go through the state inspector. If you own buildings in both towns, make two calls and keep two sets of permit notes.
Locate every overhead service drop, weatherhead, and pole near the roof edge, because crews and lifts work along the eave. Pennyrile Rural Electric serves Todd County members and is the right call if a line runs close.
Mark the line on the roof plan, ask about covering or moving a low line, and plan lift positions with clear distance; the mast flashing is sealed after the utility signs off.
Re-paneling adds new steel, removal, and disposal for each section replaced, on top of the coating that follows. Coating alone covers prep and material across the roof. That is why the panel count on the roof walk matters so much to the final number on an older Elkton building.
