Spantech builds wide span skillion roofs with minimal falls using several straight profiles in the Spantech product range.
A skillion roof is a roof with a single-sloped roof surface, often not attached to another roof surface. They may also be referred to as a mono-pitched roof, shed roof, or lean-to roof. And with Spantech’s ability to build roofs with falls of just 1 degree, they may also be considered ‘flat’ roofs.
Because Spantech panels are rolled on site, they can be manufactured to any length to provide continuous, watertight skillion roofs. The deep standing seam design of Spantech profiles allow for minimal falls of just 1 degree. Spantech profiles can also span wider than typical roof sheeting, significantly reducing the amount of structural steel required in the finished building. This wide span feature helps save construction time and costs.
The features and benefits of a Spantech skillion roof:

Similar Roof Types
A Gabled Roof is a simple roof design shaped like an inverted V.
The Woomera 300 profile is suited to Gable Roofs.
The bold ribs (standing seams) of the Woomera 300 are approximately 110mm high, so Spantech has developed a range of solutions to ensure the ridgeline remains watertight.
These include large up-turned profile ends, capped ends and waterproof foam blocks, plus generous ridgeline cap flashings.
Butterfly Roof is a V-shaped roof resembling an open book.
A box gutter separates the roof into two parts, each running towards each other at an obtuse angle. Butterfly roofs may also be referred to as a V-roof or London roof.
All Spantech’s straight profiles can be applied to Butterfly Roofs.
Note: Because of the deep profile of the Longreach 800 or Longreach 650 profiles, careful attention should be paid to the design and waterproofing of the roof around the box gutter.
Other Wide Span Roofing Applications
Spantech profiles were originally developed for roofing. But the strength and versatility of these unique profiles makes them cost effective and suitable for a wide range of applications.
Spantech builds specialised commercial projects using wide-span roll formed metal profiles developed by Spantech.
