Design of Drainage.

Roof drainage systems can be affected by a number of variables and must be designed and detailed by suitable qualified trade or professionals. The design of roof drainage aims to protect people, property and the building.

Rainwater System Design Recommendations

All Permalite® gutters are designed to be fixed with supports spaced at no more than 900mm intervals, including stop ends. All screw fasteners must be minimum 304ss with rivet fasteners being aluminium. Lap joints should have a minimum overlap of 25mm in the direction of water flow and be sealed and fastened.

The minimum gutter fall should be 1:200 for effective gutter operation and prevention of ponding. Gutter lengths should not exceed 12.0 meters, on site joints within this length should be as recommended. Bridge expansion gap with an aluminium saddle flashing should be fixed to one gutter only.

Maximum Lengths for drainage (m)

For the complete specification tables on maximum sheeting length for drainage by product, please refer to our Aluminium Roofing Solutions Manual.

Box Gutters

Box Gutters should be fabricated from aluminium sheet, preferably of alloy 5251 or 5052 and the next standard thickness to the thickness of the roof. I.e. 1.2mm thick box gutter for 0.9mm thick roof. The minimum aluminium thickness for box gutters is 0.9mm.


It is very important that flashings be made from materials that are compatible with the cladding. Flashings should conform to AS/NZS 2179.1:1994, and AS/NZS3500.3:2003.

We are able to supply flashings which are in line with the same metal specification as the roofing sheet. Where custom made flashings are required the metal should be to the following specification:

Alloy: 5251/5052 preferred, 5005 alternatively.
Temper: H32 or H34
Thickness: 0.90mm

50mm Gable roll – made from min 0.8mm marine grade aluminium and available as pre painted finish in lengths up to 3m.

Roll type ridge – made from min 0.8mm marine grade aluminium and available as pre painted finish in lengths up to 6m.

Permalite® can supply superior grade aluminium gutter, flashings, fascias and accessories for rainwater goods.
