Roof drains on flat roofs are one of the most problematic objects. Each of these systems has its own pros and cons. A major maintenance issue shared between all types of roof drains is debris removal. So often we find that inner drains are high on the roof causing water to pool around them.

There are three types of drain systems on a flat roof. The average flat roof does not have an optimized draining system. It is very critical to position drains for maximum effect. Interior drains on flat roofs are commonly used in urban areas.

With this system large square openings are made along the edge of the roof that shoot the water away from the side of the building. The main benefit of inner drains is that the system is hidden from view. Of course the best designed flat roof has the correct amount of pitch to drain the water off naturally. Scuppers are the most effective drainage solution for flat roofs.

Most draining systems on flat roofs have a poor design or are not correctly installed. Inner roof drains are used on flat roofs and include a low section or channel that collects water and feeds it into a concealed drain that leads to an underground drainage system. Inner drains are resistant to freezing but can require careful maintenance to prevent problems.
