Solving A Flat Roof's Drainage Problem

A flat roof's drainage system is one of the most important components of the roof. This is because it prevents water accumulation, something that usually goes a long way as far as extending the lifespan of a roof. Since a good roof drainage system keeps water from pooling on the roof, it prevents premature rusting of the roof's fasteners. It also protects the roof from the added weight that water accumulation exerts on the roof. This helps protect the integrity of the underlying roof structure, keeping it from sinking.

Commercial roof inspections that include the drain system are necessary if you want to enjoy the protection that a good system provides. This is because it will allow you to catch problems before they become worse. Making early repairs will then not only limit the overall repair expenses, but also extending the overall lifespan of your roof. The following are tips that will come in handy in helping you solve a flat roof drainage problem.

Roof filters

If you have a flat roof water pooling problem, the first place you should check is the roof filters. These filters trap leaves and other debris. By doing this, they help protect the drainage system's pipes from getting clogged. Unfortunately, these filters can get clogged. And when they do, they restrict the drainage system's ability to get rid of water on the roof. This then causes pooling.

To solve this problem, use a broom to sweep away any leaves and debris from the filter area. You can then rinse the area with hose. This is usually enough to get the drainage system functioning as efficiently as it should.

Drainage pipes

If your roof doesn't have filters or if its filters are worn out, then the roof's drainage pipes are likely to blame. Continued accumulation of leaves, debris, and dirt may have blocked the pipes, causing the roof drainage problems.

To confirm is this is the case, take a screwdriver and start tapping along the pipes' length. You should hear a hollow-pipe sound. If any section of the drainage piping system produces a dull thud, then you are likely dealing with a blocked pipe problem.

To solve this problem, direct pressurized water down the drainage pipe. The water pressure should be enough to dislodge any loose pieces of debris and dirt. If this doesn't work, try tapping the blocked area for a couple of minutes. The vibrations generated by the tapping will loosen part of the debris, making it easier to be washed off the drainage system. And if it still doesn't work, you will then have to disconnect the affected pipe and then physically drive a pipe or snaking tube down the drainage pipe to unclog it.
