Ogee Roof

A curved roof based on the "ogee" curve.

Ogee

Two equal and opposite arcs of a circle joined into a smooth flowing curve that is both convex and concave at the same time.

This double curved roof gets it's name from the geometric curves that define it.

Immediately reminiscent of Byzantine and eastern architecture you may think that shapes like this are not to be seen in new residential construction. Think again, scroll down!

The modern ogee curved lines of all steel roof construction.

These roofs are incredibly easy to create. The main beams do not need to be rolled to define the shape of the roof instead they are made in straight sections and the cleats that hold the steel purlins are cut to varying lengths to create the curves.
