Ice Rings At Drain Bowls
Meltwater refreezes in the drain sump overnight and lifts the membrane edge at the clamping ring. Next thaw, water runs under the sheet right into the deck.

As a Jasper commercial roofing contractor, we install and replace TPO, EPDM, and metal roofs on plants, shops, and offices across Dubois County.
Jasper commercial roofing work starts at the low points, because that is where winter meltwater collects on plant and shop roofs.

Long, flat roofs over Dubois County plants hold snow for days. It melts in afternoon sun, runs toward the drains, and refreezes there at night, so ice dams form right at the lowest point of the roof.
A new roof here gets tapered insulation that moves water toward each drain, new clamping rings and strainers, and edge metal set to shed water off the perimeter.
What we find on Jasper roofs after a hard winter.
Meltwater refreezes in the drain sump overnight and lifts the membrane edge at the clamping ring. Next thaw, water runs under the sheet right into the deck.
Ice in gutters backs water up under the edge metal. The leak shows along the exterior wall inside, often mistaken for a wall problem.
A lap that sits in standing water for days of thaw stays wet far longer than its design allows. Old tape and cold welds open first there.
Wind piles snow along parapet walls, and the melt soaks the base flashing for days. Flashing that ends too low lets water behind it.
Water that gets under the membrane at a drain spreads outward through the insulation. Cores in a ring around the drain show how far.
Units set in the line between high spots and drains sit in running water each thaw. Their curb corners leak before anything else.
The benefits that matter most on a melt-prone roof.
Tapered insulation builds slope toward each drain, so melt runs off instead of sitting. Seams and curbs spend less time underwater.
New clamping rings, strainers, and membrane flashing at each bowl close the most common winter leak point on flat plant roofs.
Edge metal and gutters set to the right height keep backed-up melt out of the wall line, where stains used to show inside.
Dry boards under a sealed membrane hold heat in the plant. Wet insulation removed at tear-off stops rotting the deck.
Each system gets the same drain-first detailing in Jasper.

Welded TPO with tapered insulation suits Jasper plants that cool in summer and face melt at the drains every winter.
Evansville TPO roofing
Rubber membrane stays flexible through Dubois County freezes, a good match for older shop and office roofs with simple layouts.
Evansville EPDM roofing
Plant roofs with exhaust and heavy units get curbs raised clear of the melt path and walkways to each unit.
Evansville industrial roofing
Sloped metal panels shed snowmelt into gutters, ending ponding on shop roofs that never drained right.

Every Jasper roof plan starts with where the water goes.


We map high and low spots, check each drain bowl and gutter, and core around the drains to see how far water has spread.
Tapered insulation gets laid out on a drawing so every area falls toward a drain. Crickets go behind curbs and along parapets.
Drain bowls get new clamping rings and strainers. Edge metal and gutters are set to shed melt off the perimeter.
Membrane, seams, and flashing finish one section at a time, sealed before the crew leaves so a thaw overnight finds nothing open.
Plant, school, and retail roofs in these towns get the same work. Building elsewhere? Call us or send us a message.
What Jasper owners ask about drains, meltwater, and cost.
Snow that melts in the afternoon refreezes overnight at drains and gutters. The ice dams hold meltwater against seams and flashing that were built to shed water, and it finds a way under. Clear drains, real slope, and tight flashing prevent most of it, along with a drain and seam check every fall.
We do. TPO, EPDM, and metal roofs on manufacturing, warehouse, and commercial buildings in Jasper are all part of the work, and each job opens with a roof survey and core samples. If your building sits just outside Jasper, call or send a message to check whether it is in reach.
Small shops get the same roof walk and written scope as large plants. On a shop roof the work often comes down to a few drains, a stretch of edge metal, and one or two curbs, which can be done in a short job with little disruption.
Price follows the roof: its size, how many layers come off, how much tapered insulation the drains need, and the curbs and edges to flash. Wet insulation found at the drains adds tear-off. After a roof walk with cores, you get a written price broken out by area.
A full scope covers tear-off or re-cover, new insulation with slope toward the drains, the membrane or panels, and flashing at every curb, wall, and drain. Edge metal and gutters are included where melt has been backing up. The written scope lists each item by roof area.
Send the building address and which drains give you trouble. We walk the roof and write up the work.
