For commercial roofing there are three common types of drainage systems. We break down each of these system types below. Check it out:
#1 Inner Drains
This type of drainage system is commonly installed at the center of a large commercial building roof. Inner drains keep water from the foundation and walls via system of pipes that drain the water through the roof.
#2 Rain Gutters
A match fit for nearly every type of building, the rain gutter is the most common type of drainage system.
Not only can this system effectively control the water flow from your roof, but it is also a cost-effective option. Just be sure that you schedule maintenance of this drainage system throughout the entire year to keep the rain gutter and downspouts in working condition.
Another cost-effective option for drainage systems is a scupper system. This system directs water through a metal box along the building’s outer walls.
Scuppers are particularly popular for flat roofed buildings.
