Fiberglass is a bit abrasive. Carbide Grit blades would probably be the best. I always used Starrett or Morse bimetal blades. They hold up the best for me due to the varied materials we cut.

Cecil,
You could also get the roof panels in PVC. They are on sale right now at Menards for 10 bucks each for a 2ft x 8ft panel. That would cut the cost well in half from the fiberglass.

I would change the design a bit and put thin a flat panel between each roof panel to increase surface area. You really only need about a 3/8" gap and the roof panels easily provide that.

I think it would be a good idea to see if you could peddle a few.
