If you are doing a corrugated roof, it is better to use metal or polycarbonate. You can ask professional roofers or even the employees in Lowes or Menards and they will tell you this Ondura stuff is not as good as metal or polycarbonate. They all cost pretty much the same (polycarbonate is a little more than metal or the Ondura panels).
I am doing a clear polycarbonate for my pen this spring. Where the pen is does not get much sun light plus we have long winters so I am going with clear rather than opaque.
This polycarbonate stuff is amazingly strong. I pulled a piece at Menards and put it on the floor. I then stepped on it and walked on it and it won't break. Some manufactures advertise it (in video) so a truck can run over it without breaking it. It will deform first but as soon as the load is off, it goes back to its original shape.
