Should Flat Roofs Hold Water

Roof systems are simply not designed to hold water.

Should flat roofs hold water.

Even flat roofs contain a slight slope to maintain positive drainage. But such a low slope holds snow and water much longer than a steeply pitched roof and therefore needs a very different material to stay watertight. There s a problem with flat roofs. Leaving water on a flat roof for less time can help minimize roofing damage.

The most common reason that flat roofs hold or pond water is because of inadequate or obstructed drainage. The design of a flat roof can sometimes prevent rain and precipitation water from draining properly making standing water a common problem. Collect dirt which may cause the growth of vegetation or telegraph mud cracking to the roof below. The good news is that this cause of ponding water is usually the easiest to correct with scheduled roof maintenance.

Water does not run off of it very easily. However puddles 1 or more inches deep that linger for days can indicate a significant problem with draining. Flat roofing is not actually flat. By their very nature flat roofs do not completely drain after it rains.

It has a very low slope between 1 4 to 1 2 inch per foot so that it drains water.
