In roof design and installation, it is important to prevent ponding water. Ponding water is an indication that something is not working correctly on the roof system. In some cases, ponding water can lead to roof collapse. If there is a rip or tear in the roof membrane, standing water can result in even larger leaks than would be present if the water was properly draining off the roof. Water standing on the roof also leads to algae growth that may damage the roof materials. Ponding water may also freeze in winter.
There are several key items that can lead to ponding water. If there is an accumulation of debris at the gutter, drainage from the roof can be affected. In addition, if the wood blocking was not correctly installed so that the insulation at the roof edge is higher than the wood blocking, ponding water may result.
Another installation mistake that can lead to poor roof drainage is not installing roof drains at the lowest point in the roof. If there is any point on the roof that is lower than the roof drain, water will pond in that area and can lead to roof problems.
