How poorly designed is your roof frame to have to use such a cheap and light roof system? Is this a mobile home?

I have never worked on one, but if the membrane is the "roof", why bother with any slate? I strongly agree with John.

Personally, I think it's junk!! We were asked to repair this type of light weight roof that was 2 years old. It's very difficult to get around the roof. Any pressure on the slate causes the slate to slide out of the hooks, because the HDPE/PTFE sheets are so slick. The hooks are do not have very much strength and slates get disheveled from stronger winds. HIGHLY ADVISE AGAINST IT!!!

does anyone have experience with so-called lightweight slate installation using interlaced PTFE membranes and no headlap. This would be like doing cedar shake. It is advertised on the web and locally as a cedar shake replacement because it's light, only 6 pounds per foot. Uses standard roofing slate and PTFE sheets not roofing felt between courses.
