As a Millersville commercial roof repair contractor, we repair winter leaks by following snowmelt routes, clearing iced outlets, and resealing seams that freeze-thaw cycles opened.
Millersville commercial roof repair calls pick up after snow, when meltwater finds joints that ordinary rain runs straight past.
Snow piled against a parapet or in a valley melts during the day and refreezes at night. Ice at gutters, scuppers, and drains holds the melt in place, and water backs up under laps and flashing that were built to shed water, never to sit in it.
We trace the melt route from the pile to the drip, clear and check each outlet, and reseal the joints the freezing has worked open.

Winter leaks follow the melt, so they show up on sunny days after snow. These pairs link each sign with what we check on the roof.
Water appears midday after a snowfall and stops once the evening turns cold.
Snow against a parapet or curb is melting onto a seam or flashing joint that has opened.
A row of heavy icicles hangs at one gutter run, and the wall below stays wet.
The gutter or downspout is frozen shut, so melt backs up under the roof edge.
Melt stands on the roof for days after a thaw, and a ceiling stain grows beside it.
Ice has blocked the drain bowl, and standing melt is working into the membrane around it.
A fan curb started leaking in winter, soon after the unit was worked on.
Service work disturbed the curb flashing, and freeze-thaw cycles opened the gap further.
Fixing the melt route keeps winter leaks from repeating every time the snow comes back.
Winter leaks call for a route-by-route check, from the snow pile to the outlet.
| Detail | Winter Problem | Repair |
|---|---|---|
| Snow against parapets and curbs | Melt sits on joints for days | Reseal or reflash the joint at the base |
| Gutters and scuppers | Ice dams back water under the edge | Clear, reset, or reflash the outlet |
| Interior drains | Iced bowls leave standing melt | Check the bowl and clamp, repair the flashing |
| Fan and unit curbs | Service work loosens flashing before winter | Repair the curb with the equipment trade |

Send the address and where the water shows after a thaw. We will trace the melt route and price the repair once the roof is safe to walk.

We ask which days the leak appears, how much snow was on the roof, and whether any equipment was serviced recently.
Once the roof is safe to walk, we follow the path from the snow pile to the drip and check every outlet along it.
If a serviced fan or unit is involved, we line up with the equipment technician so the curb is resealed after their work.
Opened seams and flashing get resealed or replaced, outlets are cleared and checked, and photos go into your file.

Warehouse leaks traced along the deck to their entry.
Metal roofs with rust hidden under panel overlaps.
Production floors protected before the roof is opened.
Farm and equipment buildings with isolated panel defects.
Fans, winter leaks, ice, and snow questions from Millersville owners.
Yes, wherever equipment movement or exhaust affects the curb flashing. We review the roof detail together with the equipment work so the preparation and reassembly fit. Done separately, a finished patch can get disturbed or exposed again to the condition that caused the leak.
Often, once the roof is safe to walk. Fastened details and welded seams can go on in cold weather, while adhesive steps wait for a dry, mild day. A temporary seal can hold the leak until then.
Heavy wet snow raises a loading question, separate from leaks, that needs a qualified evaluation. We note what we see on the roof, and the loading question goes to someone qualified to assess the structure.
Melt runs into outlets during the day and refreezes at night, building ice that blocks the flow. Damaged gutters, low spots near drains, and blocked downspouts make it worse.
Keep drains, scuppers, and gutters clear of debris before winter, and note where snow drifts against walls and curbs. Send photos of any icing, so the next inspection starts at those spots.
