As an Old Mystic commercial roof repair contractor, we fix winter leaks at parapets, scuppers, and drains, starting with a temporary seal and finishing the permanent repair.
Old Mystic commercial roof repair calls pick up when snow melts during the day and refreezes at night. Ice builds at cold parapet walls, scuppers, and drains, and meltwater backs up behind it until it rises over flashing or slips into a seam.
A winter leak usually gets two visits. The first clears ice from the outlet and seals the opening so water stops reaching the room below. The second, in milder weather, rebuilds the flashing or seam with materials that need warmth to cure.
Winter leaks tend to show up after a thaw, and each sign below traces back to ice or snow sitting somewhere specific on the roof.
Daytime melt runs toward a drain or scupper that is still frozen, so the water pools behind the ice and finds a seam.
We open the frozen outlet, clear the ice dam around it, and seal the seam the pooled water reached.
Meltwater backs up against a cold parapet and rises above the base flashing, then runs into the wall cavity.
The base flashing gets a temporary seal now and is raised higher in spring so backed-up water stays below its top edge.
Cracked joints in a scupper box let water freeze inside the wall opening when it should be draining off the building.
Ice gets chipped clear, the scupper joint is sealed for the season, and a new scupper liner goes in when weather allows.
Snow drifts against rooftop unit curbs, then melts into curb flashing joints that opened during fall temperature swings.
Snow is cleared from around the curb, the joint is sealed temporarily, and the curb flashing is rebuilt when it warms up.
Handling winter leaks in two stages protects the building now and leaves a lasting repair for the seasons ahead.
Each thaw sends more water into ceilings and walls, and repeated soaking ruins tile, drywall, and the insulation above them.
A quick temporary seal on the seam or flashing stops the water during the cold months, so interior damage stops growing before spring.
Outlets that freeze shut turn the whole roof into a holding pond every time snow melts.
Clearing ice and resealing outlet joints gets meltwater off the roof before it backs up into seams and flashing.
Base flashing that sits too low lets backed-up water overtop it during every thaw-and-freeze cycle.
Raising and rebuilding the flashing in spring keeps future meltwater below its top edge at the parapet.
Ice expanding inside small seam gaps pries them open a little further each winter.
A cold-weather patch holds the seam shut until a warm, dry day allows a full seam repair with proper adhesion.
Small shops, offices, and warehouses around Old Mystic mix flat and metal roofs, and winter hits each one in a different spot.
Flat roofs get frozen drains opened, seams patched for the season, and parapet flashing rebuilt once weather warms, with wet insulation replaced in low spots.

Metal roofs get attention at eaves and valleys where ice builds, with fasteners, laps, and eave closures resealed after snow slides or drifts.

Thaw-time leaks get traced from the ceiling stain to the frozen outlet, parapet, or curb above it, with a temporary seal placed right away.

Industrial roofs with heavy curbs and exhaust fans get snow cleared from equipment bases and curb flashing sealed where meltwater gets in.

Call and tell us when the leak started, whether it shows on sunny days after snow, and which wall or drain sits nearest the stain.
Winter repairs follow two stages, a seal for now and a full repair later, spread across these four steps.
Crews clear snow from the work area and walkways, tie off on slippery surfaces, and chip ice from frozen drains and scuppers before looking for the opening.
Once the source shows, a cold-tolerant patch or sealant goes over the seam, flashing joint, or curb so meltwater stops reaching the room below.
When surfaces are dry and temperatures allow proper curing, we come back to rebuild flashing, raise low spots, or replace the damaged membrane.
Drains and scuppers get a final flow check after the permanent repair, so the next thaw has a clear path off the roof.

Repair Cost
Snow and ice removal, the extra visit for a temporary seal, and the size of the permanent repair set most of the cost. Wet insulation found by core cuts, the number of drains or scuppers involved, and roof access in icy conditions also change the price we quote.
Businesses
Repairs are planned around opening hours, with snow cleared from walkways and roof access points before crews start. Temporary seals go on quickly to keep shops and offices dry, and the permanent flashing or seam work gets booked for a mild stretch that suits the business.
Temporary Repairs
Long enough to get through the cold stretch, but it is meant as a bridge to the permanent repair. Patches set on cold, damp surfaces bond less well than repairs made on dry membrane in mild weather, so we schedule the follow-up visit when we place the patch.
Ice Dams
Parapet walls stay colder than the middle of the roof, so meltwater refreezes as it reaches them and builds a ridge of ice. Water then backs up behind the ice and can rise above the flashing or seep into seams. Clear drains and properly raised flashing reduce the problem.
Tell us where meltwater is coming in, and we'll seal it now and plan the permanent repair for milder weather.
