Drips At Screw Rows
Washers are cracked and screws spin loose in the purlins.
As a Greenwood commercial metal roof repair contractor, we replace backed-out screws, reseal lifted laps, rebuild flashing, and swap rusted panels on steel roofs.


Greenwood commercial metal roof repair handles most steel roofs we walk. These four cases show where repair fits and where it stops.
Washers are cracked and screws spin loose in the purlins.
Sealant at the laps has dried and the panel edges have lifted.
Panels along the low edge are holed, and the field panels are solid.
Holes run across the field and the purlins under them are corroded.
Steel roofs fail at the fastener, the lap, and the edge. Each card names what drives it.
Screw heads standing proud of the rib with rust stains below them.
Daily heating and cooling works the screw loose. The washer stops sealing and water follows the shank inside.
A dark line of dirt along a panel lap and drips under it.
Factory sealant dried out, so the lap opens slightly whenever wind pushes the panels.
Orange streaks on the wall below a gutter that overflows.
Water held at the low edge kept the steel wet until the coating wore off and rust started.
Light spots on the floor below a skylight that never used to leak.
Hail cracked the translucent panel or split its lap with the steel next to it.
Flapping sounds on windy nights and a gap at the ridge.
Gusts pried trim screws loose. Rain now blows under the ridge cap and down the panel ribs.
Drips beside a unit that sits on a steel roof.
The curb cuts across several ribs, and its upslope cricket has rusted or lost its sealant.
Each repair keeps the steel roof you have and fixes the part that failed.
Worn screws are pulled and replaced with oversized ones and new washers that bite fresh steel in the purlin.
Laps are cleaned to bare metal, sealed with butyl tape, and covered; unlocked standing seams are re-crimped first.
Holed panels come out and new ones in the same rib profile and gauge go in, lapped and fastened to match.
Rusted trim, failed closures, and cracked pipe boots at ridges, walls, curbs, and eaves are replaced.
Here is the same steel roof before and after a repair visit.
Holes at the low edge grow each winter. Book an estimate and we will count the panels that need swapping.
Five steps on every steel roof.
Each run is walked from ridge to eave, with screws, laps, trim, and skylights checked along the way.
Sample screws are checked for spin and washer cracks, and purlins under rust spots are probed for strength.
Panels to swap, screw rows to change, and trim to replace are listed with photos and a price per item.
New panels match the rib pattern and gauge, and every lap and screw row is sealed before the day ends.
Swapped panels and resealed laps are photographed and dated for your records.
Membrane roofs, hidden leaks, and plant roofs each have their own service.

Seams, blisters, and drains on low-slope membrane roofs.

Stains traced uphill to the curb, boot, or lap.

Fan curbs, exhaust areas, and roofs over production lines.
Repair versus replacement, service life, seams, and flashing.
Usually, yes. Leaking screws, open laps, worn trim, and a handful of rusted panels are all repair work.
Replacement comes up when rust has holed panels across the whole roof or the frame under it has bent. Every panel run gets walked before we say which one your roof needs.
Steel roofs on commercial buildings commonly stay in service for decades, and repairs carry them through that span. The panel finish, gauge, screw type, and upkeep set the pace. Exposed screws and trim wear out first, long before the panels themselves.
The lap is cleaned to bare steel, butyl tape or sealant goes into the joint, and reinforced mastic or seam tape covers it. Screws next to the lap get tightened or replaced, since panel movement around them is what opened it.
Loose and rusted trim comes off, old sealant and closures are replaced, and flashing at ridges, walls, curbs, and eaves is refastened or rebuilt. Cracked rubber pipe boots get swapped.
Dents alone rarely leak, so dented panels usually stay. What gets repaired is what hail breaks: split laps, cracked washers, holed skylights, and damaged ridge and trim. Photos come first for any claim.
Yes. Replacement panels are ordered in the same rib profile and gauge, and trim is bent to match the shapes already on the building.
Send the address and a photo of the panels if you have one. We will walk every run and price the repairs.
