Roofing with Ondura

Looks like a good alternative worth looking into. Anyone heard of or have experience with this stuff?

Looks interesting. A lot of new roofing materials coming out lately.

Ok...
 

I have it on an outdoor open shelter building . We keep the farm tractors in it just to keep them out of direct weather.
It is a little fragile to work with, but the price is right.
You should not walk on it either on low pitches.
VERY simple to install, just like metal corrugated roofs that overlap.:)
