When it comes to flat roofs, their biggest problem isn’t always water displacement – it’s where the water goes as it travels down its low slope. For that reason, the drainage you have for your flat roof can be the deciding factor between a long-lasting roof or major problems.
There are three main drainage systems that you’re likely to have for your flat roof. The type of drainage system you have will depend on a number of factors, including square footage, climate, cost, and the building’s architecture.
Internal Drains
Internal drainage systems are composed of an interior network of gutters and pipes that are placed at intervals along the roof’s field, with the main drain located at the center.
Scuppers
Scuppers are openings at the roof’s parapet walls or perimeter curbs that project the water off and away from the building’s foundation.
Gutters
Gutters are installed at the bottom of the slope to direct water to downspouts and away from the foundation.
Each type of system comes with pros and cons. You should work closely with your Exterior Remodel & Design roofer to make the best decision for your structure and budget.
