Thomaston Commercial Roof Repair Contractor
Drain Bowls, Strainers, And The Seams Meltwater Reaches
As a Thomaston commercial roof repair contractor, we repair flat roofs that leak when drains freeze and meltwater backs up against seams and curbs.
Thomaston Commercial Roof Repair for Winter Drain Leaks
Thomaston commercial roof repair in winter often comes down to one frozen drain and the water it holds back.
When a drain ices over, daytime meltwater has nowhere to go. It pools around the drain, rises against seams, curbs, and flashing never built to sit under water, and freezes again at night, prying laps open a little more each cycle.
We repair the seams and flashing that leaked, then find out why that drain froze: a raised drain bowl, a crushed strainer, heat loss from the building, or a roof that slopes away from it.
- Drain height compared with the surrounding roof
- Strainers and clamping rings checked
- Seams and curbs inside the ponding ring repaired
- Ice-prone low spots marked for re-sloping
Ice and Meltwater Commercial Roof Repair Problems in Thomaston
Winter leaks on flat roofs trace back to water that cannot leave the roof.
Ice-Capped Drains
A thin sheet of ice over the drain grate stops all flow. Snow melting on a sunny afternoon then spreads across the roof instead of draining away.
Drain Bowls Set High
When insulation settles around a drain, the bowl ends up higher than the roof beside it. Water collects in a ring around the drain even in summer, then freezes there.
Laps Opened By Freezing
Water that seeps into a seam expands as it freezes. Each cycle widens the gap, so a lap that held all fall starts leaking by February.
Curbs Standing In Water
Rooftop unit curbs inside a ponding ring sit in slush for days. Their base flashing was built to shed water, and standing water finds the corners.
Ice Dams At Low Edges
Ice that builds along a low roof edge or gutter traps meltwater behind it. Water then backs up under edge metal and into the insulation.
Warm Spots Over Heated Rooms
Heat escaping through a poorly insulated section melts snow from below. That water refreezes at the colder drain, which is why one drain freezes while others run.
Commercial Roof Repair for Thomaston Shops and Plants

Water Reaches The Drain
Resetting a raised drain bowl and replacing a crushed strainer lets meltwater leave the roof before it can refreeze around seams and curbs.
Insulation Stays Dry Through Winter
Closing laps opened by ice keeps meltwater from soaking the insulation, which holds its value and keeps the deck from rusting.
Fewer Freeze Cycles At Joints
Once ponding rings are gone, seams and curb flashing stop sitting in slush, so the freeze and thaw that pries them open has nothing to work on.
A Plan For Re-Sloping
Low spots we mark during the repair go on a list for tapered insulation or crickets, so the owner can budget that work for a warmer season.
Thomaston Commercial Roofs: Repair Work for Frozen Drains
Repairs cover the drain itself and the roof around it.
Drain Bowl Reset And Reflash
Clamping ring removed, the drain flange cleaned, new membrane flashing and sealant installed, and the bowl lowered where it sits above the roof.
Seam Repair Inside The Ponding Ring
Laps opened by ice are cleaned, dried, and rewelded or covered with reinforced patches that run well past the damaged length.
Curb Corner Rebuilds
Base flashing at curbs that sat in meltwater gets new corner pieces and a taller wrap where the roof holds water against it.
Crickets And Tapered Insulation
Wet insulation around the drain is cut out and replaced with tapered boards or a cricket that slopes water toward the outlet.
Slush Ring Around Your Roof Drain?
Standing slush around a drain means meltwater is sitting on the seams nearby. Call and tell us which drain is iced over, and we check the roof around it first.
Our Steps for Thomaston Commercial Roof Repair in Winter
Winter drain calls follow four steps, from the outlet outward.
Inspect Your Roof
We clear snow from the drain area, check the strainer and clamping ring, and measure how far the ponding ring reaches across seams and curbs.
Stop The Active Leak
Open laps and curb corners inside the ring get a cold-rated temporary seal so meltwater stops entering while the roof is still wet.
Find Why The Drain Froze
Drain height, roof slope, and heat loss from the rooms below are checked, since a drain that sits high or runs cold will ice over again.
Make The Lasting Repair
Once conditions allow, the drain is reset and reflashed, seams are rewelded, and wet insulation near the outlet is replaced with tapered board.

What Thomaston owners ask once the drains start icing up.
Why do Thomaston flat roofs leak when roof drains freeze?
A frozen drain holds meltwater on the roof, and that water rises against seams, curbs, and flashing that were built to shed water and now sit in it. Ice also pries laps open. We repair those leaks, then check drain height, strainers, and heat loss to see why the drain keeps freezing.
Should roof drains have heat cable in winter?
Heat cable at a drain or scupper helps on some roofs, especially where one outlet freezes again and again. It treats the symptom, though, so we check drain height and slope first. A drain reset or re-slope often fixes the cause without adding power to the roof.
How often should flat roof drains be cleared before winter?
At least once in late fall, after the leaves drop, and again after any big storm. Strainers clogged with leaves freeze into solid plugs. Clearing them before the first hard freeze keeps meltwater moving off the roof through the winter.
What drives Thomaston commercial roof repair cost for drain leaks?
A simple strainer and clamping ring reset is a small repair. Price climbs when the drain bowl needs lowering, wet insulation around it must be replaced, or tapered insulation is added to fix the slope. Winter work also adds snow clearing and temporary seals.
Do you handle commercial roof repair for Thomaston businesses during winter?
Yes. We clear the work area, seal active leaks with cold-rated materials, and schedule the permanent drain work for a dry stretch. Shops and plants keep running, since the work happens on the roof.
