There are several reasons why water may pond on a flat roof. One possibility is that the roof is not pitched enough to allow proper drainage.

Another possibility is that the roof drains are blocked or clogged. If the drains are not functioning correctly, the water has nowhere to go and will pond on the roof.

If you have water ponding on your flat roof, it is important to have it inspected by a professional roofing contractor. They will be able to evaluate the problem and recommend a plan of action on the spot.

Therefore, it is important to regularly inspect your flat roof for signs of wind damage and take steps to repair any damage found.
