On many construction projects flat roofs are used as a simple and cost saving method of roofing a build. However when installing a flat roof there are several key issues which will need to be addressed. One issue is that of drainage. During heavy rain a flat roof will collect water on top of it, so a drainage system will need to be installed in order to handle the large quantity of water which will otherwise build up on top of the roof.
A solution to this potential problem is to install a water outlet. A water outlet is simply a piping system with a filter or grate on the top of the system to prevent blockages. There are many different types of outlets in different sizes which can be fitted in different areas of the roof for optimal drainage. A system like this will prevent the roof from overflowing with water during heavy rain, avoiding structural damage to the roof.
