Bushfire regulations apply in some areas.

Corrugated - Suits higher pitches

A very popular profile which maintains the old style character of the iron roof, it is economical, versatile and user friendly.

Its main limitation is its minimum pitch of 5 degrees (1 in 12). Less than this invites leaking and can shorten its life.

Mid span 1200mm   End span 900mm. Usually a minimum span of 900mm is used as this gives adequate support when sisalation is used.

Mini Flute - Decorative corrugated

Used for walls, ceilings and decorative applications, it also lends itself well to bay windows and awning canopies complimenting the main corrugated roof.

TL5 - Suits medium pitches

A useful roofing material when a 5 degree pitch is not obtainable as TL5 is suitable for a minimum pitch of 2 degrees (1 in 30) and using material of the same thickness as the corrugated example the minimum spans are increased. Mid span 1700mm  End span 1300mm. As the cost is about the same as corrugated there is a significant saving as less supports are required. (Sisalation support needs to be considered).

Decking Roofs

Because of their high rib profile decking roofs are suitable for pitches as low as 1 degree, which makes them ideal for flat roof additions and verandahs or carports where available height is limited and avoiding the need for extra materials required in a conventional roof. There are many types of decking available, but we recommend Fielders King Klip which as a hidden clip system which eliminates the need to pierce the roof with fasteners, thus eliminating potential leaks.

In the above examples material with a base metal thickness of .42mm was used, a thicker material will give a greater span, so this needs to be considered when making roofing material selections.
