If you live in an area that receives a substantial amount of rain, one thing you need to concern yourself with is water draining from the flat roof. In order to do this, you need to hire a roofing contractor to install a roof drainage system on your roof. Below is information about what will happen if you have no roof drainage as well as a type of roof drainage system you can install.
What Happens With No Roof Drainage
Roof drainage flushes water and debris into the right areas. If water is not flushed properly, the water will pool on top of the roof. This is often due to a flat roof that has no slope or a roof that has blocked drains. Pooling water will lead to problems like the roof sagging, roofing materials deteriorating much quicker, and things like algae and moss growing on the roof.
The roof membrane will also be damaged. When installing a flat roof, a roofing contractor first installs a material over the roof. This material is known as the roofing membrane. It is important as this can prevent water from leaking from your roof. Over time the roof will become damaged enough that it will have to be replaced much sooner than you planned.
Roof Drainage System
The most common type of roof drainage system is gutters and downspouts on a roof. Water runs through the gutter system to prevent the water from pooling on your roof. You will also often hear gutters referred to as troughs. Gutters can be made of a variety of materials, such as aluminum, copper, vinyl, or galvanized steel.
The downspouts are attached to the gutters and are equally as important. When water flows through the gutter system the water then flows out of the downspout. You can direct the downspout any way you wish to ensure the water does not pool near your home. You can also install downspout extenders if needed.
One downside to gutters is that you have to ensure they stay free of debris. This is because anything that gets trapped in the gutter, such as leaves, will prevent water from flowing through the gutters. Instead, the water will get backed-up and eventually get under the flat roof and onto the roofing membrane.
