Designing Roof Drainage

Roof drainage systems should be designed and detailed by a suitably qualified trade or professional in accordance with the BCA and the Australian Standards. Particular reference should be made to the correct sizing of gutter; quantity and placement of downpipes; and the provision of appropriate overflow devices.

In the design and detailing of a roof drainage system, consideration must be given to a range of factors such as:

  • rainfall intensity
  • roof catchment area
  • gutter size/capacity
  • gutter fall
  • gutter outlets (sumps, rain heads, nozzles)
  • downpipe size, quantity and placement
  • overflow consideration
  • material selection and
  • jointing
