Drainage systems are an important consideration for any flat roof, terrace or balcony. Familiar forms include eaves gutters, roof outlets such as water shoots or hoppers, as well as internal drainage systems. In warm construction types, they can be part of the tapered insulation scheme too.
There should be a smooth transition for water to flow into gutters and so they are often lined with the same materials or waterproofing membrane as found in the main horizontal areas. Flat roof construction should have a minimum fall of 1:40 to ensure a finished fall of 1:80 as per BS6229:2018. Guidance of gutter sizes, number and position are considered in guidance BS EN 12056-3.
