Ponding Water on Roof
If you get a leak due to ponding water that’s been on a flat roof for a few months, don’t blame the ponding water – blame the roof. A quality roof completely seals out water. As long as it’s maintained, it will stay sealed and
won’t leak. When a roof is built, it’s designed to prevent water from ponding. Even flat roofs have a slight slope to them. The guideline is ¼” per foot, minimum. The roof should be sloped in a way that guides water
towards the drains. As long as the drains are clear, the water won’t pond. A drain that has been clogged for too long will also cause a lot of ponding water on the roof.
