I just purchased 4 squares of Owens Corning Classic 3 tab shingles. The front and rears have a tar strip however the rear tar strip is covered with a thin plastic transparent cover that says “DO NOT REMOVE”.
The instructions seem to say that the tar cover is for storage (I gues so the shingles do not stick to each other) and it says on it “DO NOT REMOVE”. It seems intuitive that if the tar strip is there it must have a purpose which would require removal of the covering? The instructions totally gloss over this assuming you already know the answer.
Not knowing what to do on this is holding up my install. Does anyone have the proper skinny on this?
