Stripped Holes
Screws reset into worn holes spin without biting. The hole needs an oversized fastener or a new panel section. Upsized screws only go in where the purlin is solid.

As a Northampton commercial roof repair contractor, we fix fasteners, laps, skylights, and flashing on metal shops and older industrial roofs.

Northampton commercial roof repair on metal shops usually comes down to how each panel is held down.
A failed screw on an older metal roof is rarely just a screw. The washer, the hole in the panel, and the purlin under it all need checking, because a stripped hole or rusted support lets the new fastener loosen again.
We check the laps beside every failed fastener too. Panels that move enough to loosen screws often open their side laps in the same spot. Rusted supports get flagged in the same report.
Older Northampton shops and industrial buildings leak from these five areas most.
Screws reset into worn holes spin without biting. The hole needs an oversized fastener or a new panel section. Upsized screws only go in where the purlin is solid.
Surface rust on the support below a leaking screw weakens its hold and spreads under the panel. Rust that flakes under a scraper gets reported for repair.
Translucent panels go brittle and crack, and their laps with metal panels open first. New sheets are sealed into the metal laps on both sides.
Panel sidelaps open where movement has loosened the stitch screws along them. Fresh tape and stitch screws close the lap again.
Where a metal roof meets a masonry wall, the counterflashing pulls out and water runs behind it. New counterflashing is set into a cut reglet where the masonry allows.

Repairing an older metal roof at its fasteners and laps keeps the sound panels on the building.
Screws that bite into firm purlins stop the panel movement that opens laps. Stitch screws along the laps get the same check.
Cracked skylight panels get replaced with new translucent sheets of the same profile. Panels are fastened on the same pattern as the originals.
Only holed sheets come off, so the roof keeps its existing panel runs and trim. Trim and closures are reused wherever they are still sound enough.
Notes on rust and supports across the roof help plan the next round of work. Supports with heavy rust are flagged for a structural look.

Get An EstimateFour stages on every metal shop roof.
Walk the panels along the purlin lines on safe footing, checking screws, side and end laps, skylight panels, and the flashing where roof meets wall.
Suspect screws are pulled so the hole and the purlin under it can be checked for rust and stripping before anything goes back in.
Holes get oversized fasteners or a panel swap, and the laps beside them receive new butyl tape and stitch screws.
Photos and a sketch show each repaired fastener, every swapped panel, and the rusted supports to watch on future visits.

Answers for Northampton shop and building owners.

Check the washer, the hole in the panel, and the support under it together, plus the laps nearby for movement or rust. A fix that only adds sealant over a loose fastener leaves it free to move, so we restore real attachment first.
We do. Metal shop roofs in Northampton are repaired from our Allentown base, covering fasteners, laps, skylight panels, and wall flashing on older buildings.
Many Northampton properties pair a metal shop with a flat office wing. Each roof gets the repair method that fits its own system, and both go into one written scope.
Translucent panels turn brittle with age and crack around their fasteners, and their laps with steel panels loosen. Replacing the cracked panel with a matching profile closes the leak and brings back daylight.
Screws with rusted heads or cracked washers are next in line to leak. Replacing them during a repair visit, after checking the purlin, keeps the panel tight around them.
Fastener resets and panel swaps work in cold weather as long as the panels are dry and free of frost. Sealant tapes need clean, dry laps, so work on frosty mornings starts once the sun has dried the roof.
