For notes on the effective design, detailing , installation and maintenance of residential roof drainage systems, see the Fact Sheet: Water Overflow & Residential Gutters.

Important Information regarding Gutters and Roof Drainage System Design:

The design and installation of guttering and downpipe systems needs to comply with the Building Code of Australia and referenced Australian Standards AS/NZS 3500 part 3 and AS/NZS 3500 part 5; as well as the Plumbing Code of Practice for your state. For more information about the relevant standards, please consult the office of Fair Training NSW website and their brochure on overflow measures for residential gutters or your local Fair Trading Authority. Further information can also be found from the Australian Steel Institute in their document "Requirements for Overflow Measures for “High Front” Quad Gutters".

The Legislation in some states (including New South Wales) requires that all gutter and downpipe installations be undertaken by a suitably licensed installer. (In New South Wales this means an installer who holds a current certificate issued by the NSW Office of Fair Trading.) Please refer to relevant Government agency for further details.

Metroll’s hi front quad gutter has 8000 mm2 of slot capacity in every ten metres of gutter. Therefore if a 100 x 75 downpipe or smaller downpipe is required for normal water flow when designed in correctly for a 10m length of gutter, the fixed overflows will be not smaller than the downpipes connected to the eaves gutter. The spreadsheet attached is useful to allow calculation of the rainfall rate for which the slots provided for Metroll hi-front quad gutter and overflow between the back of the gutter and the fascia for a specified distance from the ridge to the gutter. The user simply changes the distance from ridge to gutter to get the appropriate answer, and then can compare that information to the 20 year rainfall intensity in mm/h that can be determined using the Create IFD tool at . The location of your site for entry into that tool can be obtained from In circumstances where the overflow capacity is insufficient, additional overflow measures will be required. These can include the measures referred to in"Requirements for Overflow Measures for “High Front” Quad Gutters".And also the use of our ‘spacer spring clip’. That spring clip will provide additional overflow capacity, and the calculated overflow capacity can be obtained using the modified spreadsheet tool available by clicking this link.
