When it comes to commercial construction, flat roofs are not new. Having said that, the flat roofs have always been troubled by faulty drainage system, which is often the result of improper construction. During rain and snow, water can pool up and cause leaks. Ice formation during winter, and deterioration in the roof membrane can also occur as a result of water pooling.
So, what’s the solution?
In this short write-up we will discuss three amazing drainage system that can prevent the flat roofs from rain and snow damage.
Interior Drains
Water usually accumulates in the center of the roof. Through interior drains you can deal with that problem. It is a system where drainage pipes are placed at small distance from each other and near the center of the roof. The drain is connected to the external network of pipes and gutters that flushes out the water from the center of the roof. Strainer is usually fitted on the drains that prevent leaves and debris from getting in and choking the drain.
Interior drains are pleasing to the eyes because the system of drains and pipes is not visible from the outside. Having said that, interior drains are a little costly when compared with exterior drainage system. Interior drains usually require less maintenance and are durable too, so when you talk about the value for your investment, it is definitely worth it!
Gutters
These are open pipes that are connected to the edges of the roof designed to carry away the water as it drains from the roof. Gutters, although not the most beautiful drainage system in the world is considered to the most cost effective one. You don’t need any modification in the roof itself if you’re planning to install gutters. Good with moderate level of rain and snow, gutters do require regular maintenance as debris and leaves can easily choke the pipes.
Scuppers
Scuppers are small outlets fitted at the edges of the roof. They take the draining water away from the building. Scuppers are useful and helps protect the foundation in the longer run. Scuppers are more pocket friendly than interior drains and slightly expensive to install than gutters.
One of the downside of scuppers is that they will only word efficiently if the roof is designed in a slope and the water from the roof flows towards them naturally. They are a good option in dealing with heavy rains but not very useful in areas that get a lot of snow.
Conclusion
Deciding the type of drainage system for your roof will depend on your budget, the area you live in and most importantly what the design engineers and contractors think about it. We advise our readers to make sure that contractors you hire do have the experience in installing all these types of drainage system because the effectiveness of a drainage system is one thing and installing it properly is another! So, do you research and keep an eye on the contractor!
Until next time, Adios!
