Drainage
Blocked drains and outlets differ from structural low spots or inadequate slope. The cause determines whether cleaning, detail work or a larger drainage solution is needed.
A low-slope roof leak needs a compatible repair and a look beneath the surface. Seams, curbs, drains and wet layers can change the size of the job.

Water above a shop floor can begin at a curb, a damaged seam or a drain detail. On a low-slope roof, water can also move within the assembly before it becomes visible inside. The indoor leak is a clue to follow back to the actual opening.
We consider the membrane type and the condition around the failure before choosing repair materials. TPO, EPDM and bituminous roofs need different repair methods and surface preparation.

The roof needs to shed water and keep the layers below serviceable.
Blocked drains and outlets differ from structural low spots or inadequate slope. The cause determines whether cleaning, detail work or a larger drainage solution is needed.
Wet insulation can extend beyond the visible opening. A surface patch alone does not remove that moisture or restore damaged layers.
The repair needs to suit the actual covering and connect to prepared, sound material. Our commercial system pages explain the different membranes.
A defined repair area helps the building keep operating around the work.
Tell us which room or tenant area is affected and whether water is active. That helps connect the roof concern with the building use.
Entrances, loading areas and equipment service paths affect access and staging. The repair plan needs to account for them.
Repeated defects or wet layers across the assembly are reasons to consider commercial replacement alongside further patching.
No. Water can move between roof layers or along the deck before reaching the interior. The repair needs to address the actual entry point.
No. Materials and repair methods must be compatible with the existing system. An unrelated product can interfere with adhesion or future repair work.
No. Drainage and the roof condition need attention. Standing water can reflect a blocked outlet, a low area or another issue requiring a specific remedy.
