Ponding Water Repair

What This Service Involves

On flat and low-slope Northwest roofs, our sheer volume of rain exposes any spot where drainage falls short and water simply sits. Ponding accelerates membrane breakdown, adds weight, and eventually finds a seam to leak through during weeks of continuous wet weather. Our crews correct the drainage with tapered insulation, added drains, or membrane repairs so water sheds instead of pooling. Eliminating standing water is essential to the longevity of any low-slope system here.

Benefits

Eliminates standing water that degrades membranes; Improves drainage with tapering or added drains; Reduces structural load from pooled water; Extends the life of low-slope roofing; Prevents seam leaks caused by prolonged ponding

Our Process

1) Map ponding areas and trace drainage paths; 2) Determine whether slope or drains are lacking; 3) Add tapered insulation, drains, or membrane fixes; 4) Test drainage and confirm water sheds fully

What Affects the Cost

Size and depth of ponding areas; Drainage corrections required; Type of low-slope membrane; Structural adjustments for slope; Roof access and equipment needs

Best Time of Year

Ponding is most visible during sustained fall and winter rain, and corrections are best built during a dry stretch.
