Spengler Industries Quadro Roof panels


Hi Guys,
One of my general Contractors has asked me to bid on the Quadro Roof panels. Basic 4:12 roof pitch with a few Hips, 30 square roof. I have never installed them, Has anyone any experience with these Roof panels? Any feedback would be greatly appreciated,
Thank you


No but charge at least 2x as much as you think it should cost.

This may not be enough either…
