As a Groton commercial roof repair contractor, we find the source of the leak or damage and repair flat, metal, and industrial roofs on working buildings.
Most Groton commercial roof repair calls start with one of these four signs, and each one points to a different part of the roof.
Water pushed sideways through open laps, coping joints, or wall flashing gets carried along the deck before it drips inside.
We trace the path from the stain back uphill on the roof, test the suspect joints, and reseal or reflash the one letting water in.
Clogged strainers, a drain sitting higher than the roof around it, or crushed insulation leaves a low spot in the field.
Drains get cleared and reset, wet insulation in the low area is cut out, and tapered pieces move water toward the outlet.
Salt air and age wear out rubber washers, and rust starts where cut edges and fastener heads stay damp.
Failed screws come out, oversized fasteners with new washers go in, and rusted-through panels are swapped for matching profiles.
Service traffic, vibration, and heat from the equipment crack the flashing where the curb meets the roof.
We cut back the damaged membrane, reflash the curb, and add walkway pads on the path technicians use.
Moisture readings and core cuts decide this, so the answer comes from the roof itself. Here is how the three paths compare.
One open seam, boot, or flashing joint
Dry around the opening
Seal, patch, or reflash that one spot
Leaks caught after a storm or two
Ponding, rust holes, or a stain that keeps returning
Wet in one area, dry around it
Cut out wet layers, rebuild the section, tie into the roof
Damage limited to one part of the roof
Leaks moving around the roof every season
Wet across large areas
Tear-off and a new roof system
Roofs at the end of their life
Four repair services cover the roofs on most Groton commercial buildings, from small shops to plants.
Membrane seams, punctures, blisters, and drains on low-slope roofs over offices, shops, and warehouses. The damaged area gets rebuilt and tied into the field around it.
Exposed-fastener and standing seam roofs on shops, marine buildings, and warehouses, where screws, laps, and edge trim let go first near the water.
Active leaks traced from the ceiling stain back to the seam, curb, or flashing that lets water in, with moisture readings before any patch goes down.
Plant and fabrication roofs with exhaust fans, heavy curbs, and wide spans, repaired in sections so production keeps running below.
Call and tell us where the water shows up inside, what the weather was doing, and whether drains or scuppers sit near that spot.
Every repair follows the same order, so the patch goes where the water actually gets in.
Inside, we mark every stain and drip. Up top, we check the seams, curbs, drains, and flashing uphill of each mark and take moisture readings across the area.
Core cuts show whether insulation under the membrane is dry, damp, or soaked. That result sets the size of the repair before any material gets ordered.
Membrane gets patched with the same type already on the roof, metal panels with the same rib profile, and flashing with compatible sealants and fasteners.
You get photos of the source, the repair, and anything else on the roof worth watching, so you know what to check before the next storm.
Each repair targets a part of the roof that wears out on its own schedule.
Heat, cold, and building movement open membrane seams and metal end laps a little more every season.
Cleaned, dried, and resealed seams shed water again, and the repair ties into dry material on both sides.
Leaves, gravel, and grit fill strainers, and loose clamping rings let water slip under the membrane at the drain bowl.
Reset rings, new strainers, and reflashed drain bowls move water off the roof before it backs up.
Sealant joints at curbs, parapets, and wall flashing dry out, crack, and pull away first.
New flashing and counterflashing close the gaps where most commercial roof leaks start.
Coastal salt corrodes screw heads, coping, and edge trim, so fasteners loosen and the roof edge lifts in wind.
Corroded parts are replaced with metal suited to salt exposure, and the edge is fastened down again.

Repairs
Membrane seams, punctures, drains, curb flashing, metal panels, fasteners, and edge trim make up most of the work on flat, metal, and industrial roofs. We find where the water actually enters first, since it often travels several feet along the deck before it drips inside.
Sections
Yes, when the rest of the roof is dry and holding. Damaged membrane, insulation, or panels in that area are cut out and replaced, and the new material ties into the existing roof. Moisture checks around the edges confirm the damage stopped where we think it did.
Repair Or Replace
Readings decide it. A few failed seams or flashings on an otherwise dry roof call for repair. Wet insulation across many bays, seams failing all over the field, or a damaged deck point to replacement. We show you the moisture map so the choice rests on evidence.
Leases
That depends on how the lease assigns roof work. Some put it on the landlord, some split routine repairs from major work, and net leases can pass roof costs to tenants. Read the roof clause before approving work; our photos and findings help both sides agree on scope.
Cost
Damaged area size, the roof system, and how much wet insulation turns up in core cuts matter most. Flashing count, curbs and drains involved, roof height, access, and staging also move the price. Each repair is priced after the roof has been inspected.
First Call
Groton and the fifteen towns listed above are covered. Move stock away from the drip, catch the water, and call with the room, the nearest wall or column, and the weather. Those details point the crew to the right section of roof.
Tell us what you see on the ceiling or the roof, and we will set up a visit to find the source and repair it.
