Commercial Roof Drainage and Ponding Repair
After an Arlington storm, ponding near a roof drain might come from a blocked strainer, a sag, or a downstream restriction. A wet spot inside a retail suite near an I-20 parapet can also come from overflow that has travelled along a wall. Establish how each roof section is supposed to drain before choosing a repair.
Separate roof drainage from property and municipal concerns
Map drains, scuppers, and overflow paths to their discharge points. Note whether water is collecting on the membrane, backing up at a private outlet, or affecting an area downstream. Arlington publishes separate reporting guidance for public stormwater concerns. The property team should record where it sees the problem so it can direct the issue to the appropriate owner.
Verify what remains after debris is removed
Photograph the standing water and drain detail before clearing debris. Revisit the condition after another rain where practical. Persistent water near a low point or overflow can require a roof slope review, a plumbing investigation, or an assembly repair. On an expanded industrial building, inspect transitions that can separate two otherwise adjacent drainage areas.
Check downstream effects before changing an outlet
A revised scupper or discharge can move water toward an occupied walkway or loading apron. Show the existing and proposed discharge path to the building team before approving the change. If it affects the site's drainage system, coordinate review of that connection with the appropriate design or facilities contact.
