As a Gales Ferry commercial roof repair contractor, we fix metal shop roofs where panels rust through, skylights crack, and end laps start dripping.
Gales Ferry commercial roof repair often means a steel building: a contractor's shop, an equipment barn, or a storage building with exposed-fastener panels. Those roofs leak at the same few places, and we repair them panel by panel instead of reroofing the whole span.
Shop roofs also carry translucent skylight panels that yellow and crack with age. We swap brittle skylight panels for new ones in the matching rib profile, then reseal the side laps so each opening sheds water like the steel around it.
These are the leaks shop owners describe most, with the roof detail behind each one and the repair that stops it.
Rubber washers under the fastener heads harden and split, and screws backed out by heat cycling leave open holes along each purlin line.
Each failed screw comes out, an oversized screw with a new washer goes in, and every head in the run gets sealed.
Old fiberglass skylight panels crack along the ribs, and the sealant at their side laps pulls loose from the steel next to them.
New skylight panels in the same profile go in, with butyl tape at each lap and stitch screws spaced to hold the joint closed.
End laps where two panels overlap mid-run lose their tape seal, and water driven uphill by wind slips into the joint.
We open the lap, clean off dirt and old mastic, lay fresh butyl tape, and restitch the joint before sealing the screw heads.
Debris and standing water at the low edge rust panels from the top side until small holes open just above the eave trim.
Rusted sections are cut out or whole panels replaced, and the eave closure strips are renewed so water stops backing up.
Each repair targets one part of the roof that wears out first on a working shop, and here is what that work changes.
Washers dry out in sun and cold until every screw along a purlin becomes a small leak point.
Replacing the fasteners along that whole line closes the holes at once and keeps you from chasing one drip after another.
Translucent panels lose strength and color, and their thin edges split where the screws pass through them.
New panels bring back daylight and close the cracks, and fresh lap seals keep water from tracking under the steel beside them.
Mid-run end laps open slightly each season as the roof expands and contracts with temperature swings.
A retaped and restitched lap holds the panels tight together again, leaving wind-driven rain no gap to enter.
Leaves, grit, and melting snow collect at the low edge, keeping the steel wet long after a storm passes.
Fresh panel sections and new closure strips at the eave let water drain off cleanly into the gutter below.
Most shop roofs here are metal, but plenty of these properties also have a flat office section or a heavy equipment building out back.
A low-slope office or showroom attached to a steel shop needs its own membrane seams, drains, and wall flashing repaired where it meets the taller metal wall.
Flat Roof Repair details
Panel replacement, skylight swaps, end lap resealing, and fastener renewal on exposed-fastener and standing seam shop roofs, matched to the existing rib profile and color.
Commercial Metal Roof Repair details
When water reaches a workbench or parts rack, we trace it back along purlins and laps to the opening on the roof before cutting anything open.
Commercial Roof Leak Repair details
Fabrication and equipment buildings with exhaust fans, vent stacks, and heavy curbs get flashing and membrane repairs around each penetration while the work inside continues.
Industrial Roof Repair details
Call and tell us where the drip lands, whether it follows rain or melting snow, and if a skylight sits nearby. That narrows down the leak before anyone climbs up.
Four steps take a shop roof from first walk to a closed repair, with the work planned around your doors and equipment.
Starting at the eave, we check each fastener line, end lap, skylight panel, and ridge cap, marking every failed spot with paint so the repair list matches the roof.
From inside the shop, drip marks on purlins and stained insulation facing show which laps or skylights are letting water reach the floor below.
Damaged panels and skylights come out first, then new tape, closures, and oversized screws go in so each repaired section sheds water before we leave.
A hose run over the repaired laps and skylight openings, with someone watching from below, confirms the leak points are closed before the job is signed off.
We take commercial roof repair work in Gales Ferry and fourteen other towns around Groton. If your building sits outside the list, call us or send us a message and we'll say whether we can reach it.
Repair Cost
The number of panels and skylights that need replacing sets most of the price. Fastener count, how many end laps must be opened and retaped, roof height, lift access around the building, and whether insulation under the leak is wet also change the cost. We price the repair after walking every panel run.
Finding Help
Call us with the building's location and a short description of the leak. We repair commercial roofs in Gales Ferry and the towns around Groton, and we start every job by walking the roof so the repair plan matches what is actually up there, panel by panel.
Skylights
Yes, as long as the steel panels next to the skylight are solid. We remove the cracked translucent panel, install a new one in the same rib profile, tape and stitch both side laps, and seal the fasteners. Rusted steel beside the opening gets replaced in the same visit.
Winter Work
Fastener replacement and panel swaps can happen in cold weather once snow and ice are cleared from the work area. Some sealants and tapes need a dry surface and minimum temperatures, so a lap gets a temporary fix first and a permanent reseal when it warms up.
Repair Or Replace
Replacement makes sense when rust has thinned most panels across the roof, purlins are corroded, or leaks keep opening at new laps every season. Isolated holes, a few bad skylights, and failed fastener lines are repair work. We show you photos of each area so the decision rests on what the steel looks like.
Tell us which panels, skylights, or laps are leaking, and we'll set up a roof walk to plan the repair.
