I'm installing a small, 3 square SA "Liberty" roof. The base sheet was a dream and it worked perfectly. The cap sheet is sucking. I assumed that the same method would be used on the cap sheet but I was wrong. The plastic sheet did not want to pull out easily like the base. It was a combination of the weight and the interference from the overlap area, both the plastic and the slightly rough membrane. Apparently you have to flop half of the whole length over and that will be tricky. If things don't go perfectly, it will be a shit show.
@@sirjohnahayfalcon It was a new product for me and I knew it would be a gamble. I'm 70 so it may last a lifetime :). If not, I will accept the consequences.......or paint it. :)
If you are thinking long term re roofing, the first nailed down base sheet will allow the adhesive layers to be removed easily. If you stick that shit to OSB, it ain't comin off.
@@jackconnolly2665 If considering the re-roofing, how about keep the plastic sheet and not pull out from the bottom of the nail base sheet, use nails to hold the base sheet on the plywood roof. Is that working?
@@geoffyang9984 The stuff I used was far too slick with the plastic in place. It would be so slippery that you'd need 10X the nails (and nail holes) to keep it in place. When completed, the adhesive turns it into one large stuck down piece with no nail penetrations.

I had to paint a liberty roll roof with gaco silicone because the Liberty roll wasn’t waterproof

Is the base sheet necessary before installing the CAP sheet on all roof types? I'm wanting to apply over a metal roof.
yes it is
Where to buy it
ABC Supply.
Why use two base sheets? One wasnt even fiber
