Is Your Flat Roof Draining Water?

Many businesses and some homes have flat roofs. As the name implies, a flat roof is in contrast to the sloped roofs that are most common in residential homes. If you are concerned about your roof or looking to replace your roof, you should call flat roof experts. There are unique challenges to a flat roof that not every roofer is equipped to handle. One of the biggest challenges of a flat roof that isn’t a consideration with a sloped roof is the retention of water.

Water Retention

Because they are flat, the roofs of business have a propensity to gather water. As it rains, that water ponds on the top of the roof and won’t drain. Many managers who see the ponding on their roofs worry that it could be doing some kind of damage. That’s especially true if the roof is sagging where the ponds occur. The answer is more complex than a simple yes or no. Roofs can be designed to retain water or designed to drain it. Some businesses have flat roofs that are designed to hold onto water after it rains. The water helps cool off the roof and the entire building. The ponds act the same way sweat does. As the water evaporates, it takes heat with it and cools down the surface. Talented Wiltshire roofers can tell you if your roof is supposed to retain water.

Sloping Problems

Roofs that aren’t supposed to retain water are built with a tiny slope. That slope is almost imperceptible but it is enough to cause water to run downhill. If your roof is holding water, it could be because the slope was never steep enough. It’s also possible that the roofing material has just warped and shifted enough to negate the slope. Whatever the case may be, knowledgeable experts can help you determine if it’s a problem and how to fix it.
