Traditional corrugate roofing requires a minimum pitch of 8 degrees — a limitation which can make it difficult to preserve the look of lower pitch heritage roofs and verandahs, and can limit design possibilities on modern projects. Roofing Industries offers two innovative corrugate profiles which overcome this issue, enabling roof pitches as low as 3 or 4 degrees while maintaining a corrugate look.

True Oak Corrugate: Preserving the traditional corrugate look on heritage roofs down to 4 degrees

True Oak Corrugate delivers a classic corrugate look with a deeper, rounder sinusoidal wave profile. This profile offers greater strength and spanning compared to traditional corrugates, and with a minor adjustment in rib height can be installed as low as 4 degrees. 

True Oak Corrugate's suitability for lower roof pitches has made it a popular choice for refurbishing Victorian-era heritage builds which often feature roofs and verandahs at pitches below 8 degrees. This allows architects to preserve the traditional corrugate look of the building, while meeting modern performance standards. The profile is also increasingly specified for modern builds where it provides a striking corrugate look. 

True Oak Deep: Bringing a bold corrugate look to modern roofs as low as 3 degrees

For projects where an even bolder corrugate aesthetic is desired, Roofing Industries provides True Oak Deep. This heavier gauge profile has a significantly higher rib height than traditional corrugate, creating a strikingly deep sinusoidal wave that creates distinct shadowlines. The profile can be installed as low as 3 degrees, bringing new architectural options to low pitch roof design. 

Originally designed as a replacement for traditional fibre cement corrugated, True Oak Deep has become a popular choice for new builds due to its eye-catching appearance, exceptional strength and suitability for lower pitched roof designs.
