Rated 1 out of 5 by from Such a piece of junk!!! the product supposed to stick together on the sides. but the seams opened when a little rain happened. and now i have to redo the whole thing. such a garbage. even if you heat it with the gun it will not hold the seams. i would not trust such a horrible product.

Says "suitable for primed plywood decks". What is the recommended primer?

Asked by: Etangbuilder
According to GAF, Home Depot does not carry this type of primer. GAF could not suggest a different brand of similar primer outside the U.S. So customers should think twice about buying this product without the recommended deck primer. How about a comment from Home Depot Canada?

Could i apply the cap sheet on bare plywood? aka does the bases sheet must be installed?

Asked by: Bill
Hello, you do not need to use an underlayment with the Liberty Cap sheet. The Liberty Cap can be applied directly to primed plywood. You can prime the plywood with an ASTM D41 type asphalt primer. Our primer is Matrix 307. Thanks for your question.

Can this product be used over foam board insulation for the exposed area of foundation walls?

Asked by: Janette
It will stick to almost anything permanently. The adhesive is very aggressive. I don’t know if foam board is strong enough to carry its weight though.  Depending on the quality of the foam, it could tear apart under weight of membrane.  But prob okay?  It will rip the top layer of plywood off if you try to remove it

Link provided on page only gives pdf Installation Instructions in French. Can you please include a link to English Installation Instructions ?

Asked by: But I like my adblocker
The Product was easy to apply to the flat roof after cutting it to length as the roll was too heavy for one person to lift it to the roof , I know it said two people to install but I am one person doing it myself . it was easy to lay it out and apply it . I rate it a 10

I'm applying Asphalt primer \[ASTM D41\] on my low slope pressure treated plywood roof. The instructions indicate it requires up to 4 hours to dry. Is there a maximum time frame before applying self-adhesive cap sheets ? Say can I wait until the next.

Asked by: Mario55
I waited until the next day and it was fine

I was told that the drip edges should not be against the fascia [1"x 8" pine]. there should be a gap between them ... Correct ? The fascia can be installed after the drip edges have been attached to the roof edges and the cap sheets installed ...Correct ?

Asked by: Mario55
Yes. Drip edge first the. The roll roofing past the drip edge 1/2”. I sealed all edges with roofing sealer.

Do I have to put shingles on top of this product

Asked by: Loco 2020
The Liberty Cap Sheet is intended to be installed on low slope roof applications. The Liberty Cap Sheet has a granule surface and it is not recommended to install shingles over this product.
