Corroded Edge Trim
Edge trim near the water rusts at every cut and bend, and loose trim lets wind catch the membrane.
New edge metal suited to salt exposure, fastened and sealed, holds the membrane down along the perimeter.
As a Stonington commercial roof repair contractor, we replace corroded edge metal, coping, and fasteners on waterfront and marine buildings.


Stonington commercial roof repair near the water is mostly a fight with salt. Salt settles on coping, edge trim, flashing, and fastener heads, and corrosion starts at cut edges and scratches. As the metal rusts, sealant joints let go and screws lose their grip.
We replace the corroded parts with materials suited to coastal exposure, reseal every joint we open, and check nearby fasteners while we are on the roof. Marine buildings with wide spans and heavy equipment get the same attention at curbs, seams, and crane bay openings, where salt and exhaust work on the flashing together.
Salt air shows up on roofs in a few clear ways, and most of them start at metal. Each sign below points to a repair we make on waterfront buildings.
Edge trim and drip metal corrode at cut ends and scratches, and rust washes down the wall in long streaks.
Corroded trim comes off, new edge metal suited to coastal exposure goes on, and the membrane is stripped in and sealed.
Fasteners holding the coping rust and lose their grip, so caps shift in wind and open the joints between sections.
We refasten or replace the coping, install new joint covers, and seal the cap so rain stays out of the wall.
Salt eats the washers and screw heads on metal panels, opening small holes along every fastener line.
Failed screws are pulled and replaced with oversized fasteners and new washers, then the heads are sealed along each row.
Sealant loses its bond as the metal beneath it rusts, leaving gaps at counterflashing and penetration joints.
Crews clean rust back to firm metal, treat it, and apply new sealant or replace the flashing piece entirely.
Replacing corroded parts early keeps a small rust problem from opening leak paths along the whole roof edge.

New edge metal suited to salt exposure, fastened and sealed, holds the membrane down along the perimeter.
Screws and washers on metal roofs corrode first, and each failed one becomes a small leak.
Replacing whole fastener lines at once, with sealed heads, ends the chase after one drip at a time.
Coping joints open as fasteners rust and caps shift, letting rain into the top of the wall.
Refastened caps with new joint covers keep water out of the wall and the membrane behind it.
Marine and fabrication roofs carry heavy equipment whose curbs crack their flashing as the roof moves.
Reflashing each curb and treating nearby rusted metal closes the openings where water reaches the deck.
Four repair services cover the warehouses, marine buildings, and commercial blocks we work on across Stonington.

Commercial blocks with flat membrane roofs leak at seams, drains, and parapet flashing. Flat roof repair fixes those details and replaces corroded edge metal along the perimeter.

Metal warehouses and marine buildings lose screws and panel edges to salt. We replace fasteners, reseal laps, and swap panels that have rusted through.

Water inside a waterfront building gets traced to the rusted flashing, open joint, or fastener line letting it in before any repair starts.

Wide marine and fabrication roofs with heavy equipment need industrial roof repair at curbs, crane bay openings, and seams worn by exhaust and salt.

Call and tell us how close the building sits to the water, what the roof is made of, and where you see rust or drips.
Salt damage repairs follow four steps so every corroded part is found and replaced under one plan.
First we walk the whole roof edge, the coping, and every fastener line, photographing rust, loose caps, and failed sealant joints.
Every corroded part is marked as surface rust to treat or metal rusted through to replace, so the repair scope is clear to the owner.
Crews install new edge metal, coping covers, and fasteners suited to coastal exposure and reseal each joint they open.
Before leaving, nearby fasteners, curbs, and flashing get a final check so the next weak spot is on record for the owner.

Coverage
Yes. We take commercial roof repair work across Stonington, Pawcatuck included, on warehouses, marine-related buildings, and commercial blocks. Roofs near the water often need corroded fasteners, edge metal, and flashing replaced, and we make those repairs with materials meant for salt exposure.
Repair Cost
How much metal has rusted through sets the price more than anything else. Surface rust can be cleaned and treated, while panels, coping, or trim that are thin or holed need replacing. Roof size, access, the number of fastener lines, and any wet insulation found also change the total.
Marine Buildings
Waterfront repairs cover edge metal, coping, fasteners, and flashing joints, plus curbs on buildings with heavy equipment. We treat surface rust, replace metal that has thinned, and reseal every joint we open, so the repaired edge holds up to salt and wind.
Choosing Help
Ask which edge metal, fasteners, and sealants they plan to use near salt water, and how they decide between treating and replacing corroded parts. Request photos of each problem before work and of the repaired joints after. Clear answers show they have planned for coastal exposure.
Repair Or Replace
Repair works while corrosion stays at the surface, edges, and fasteners. Once most panels have thinned or rusted through across the roof, repair costs climb past what makes sense, and replacement becomes the practical choice. A close look at panel thickness shows which side of that line the roof sits on.
