DuBois Commercial Roofing With Drains in the Scope
DuBois commercial roofing on a warehouse treats every drain as part of the replacement, since a new membrane over a bad outlet repeats the old leak.
We inspect each drain bowl, clamp ring, and pipe connection, then check the slope around it. Bowls set high, cracked rings, and sagging insulation all hold water, and each one gets fixed before new membrane goes down.
Drains also need to work during construction. Temporary outlets and the order of tear-off keep water moving off open and finished sections, so rain never pools on bare deck or fresh insulation.
- Bowl, clamp ring, and pipe checked at each drain
- Tapered board and crickets set to each outlet
- Temporary water routes kept open during work

Most leaks we trace on area warehouses start at or near a drain.
Water Inside Below a Drain
Call NowLeaks right under a drain point to a failed clamp ring or a cracked pipe connection.
Bowls Sitting Above the Roof Surface
Repair FirstA bowl set too high leaves a ring of standing water around it. Tapered sumps fix the height.
Freeze-Thaw Damage at Outlets
WatchIce in a ponded ring cracks the membrane, and each thaw lets more water in.
Sagging Insulation Near Drains
Repair FirstWet, crushed board lowers the roof surface and creates ponding water on a flat roof.
Missing Overflow Drains or Scuppers
WatchA single blocked drain with no overflow lets water climb the curbs and walls.
Rusted Deck Under Ponded Areas
Call NowYears of standing water can rust steel deck flutes under the low spots. Cores and a look from below show whether those sheets need replacing before new insulation goes down.

DuBois Owner Questions
Answers for warehouses and plants in DuBois.
Drains
How Should a Warehouse Plan for Drains During Roof Replacement?
Include drains in the scope as working parts of the new roof. We inspect connections and the surrounding slope, then tie new roof details into the existing drainage. Outlets also need to work during construction so no opened or finished section collects water.
When Is Roof Drain Replacement Needed?
When the bowl is cracked, the clamp ring is corroded, or the bowl sits so high that tapered sumps cannot fix it. Many drains only need new inserts or rings, and the inspection shows which. Pipe connections below the deck get checked from inside when access allows.
Ponding
What Causes Ponding Water on a Flat Roof?
Sagging or wet insulation, drains set above the roof surface, deflected deck, or too little slope toward outlets. Cores and a level survey show which cause applies, and the reroof fixes it with tapered board and drain work.
Is Some Standing Water After Rain Normal?
Small puddles that dry within a day or two are common. Water that stays longer, freezes, or grows each year signals a slope or drain problem worth fixing in the reroof. Ponding also hides membrane damage, so we probe those areas closely.
Warehouses
How Does Warehouse Roof Drainage Change in a Reroof?
New tapered insulation, crickets between drains, and sumps at each bowl. Overflow drains or scuppers get added where the roof layout calls for them. Downspouts and leaders get checked so water leaving the roof has somewhere to go.
Will Stock Stay Dry During the Work?
Each section is covered by the end of the day, and drains stay working throughout. We also protect stock under the active section when the owner asks. Racks near drains get extra attention, since a leak there would land first.
