I seem to recall the last time I did a roofing job (11 years ago), I recall removing the thin plastic film on the glue strip, which I assumed was there to prevent the shingles getting all stuck together in the bundle.
However, I'm roofing a new shed and this film is really tough to pull off - not to mention messy. It'll take me longer to pull the film strip than lay the shingles.
Question; is this designed to melt/dissolve; i.e., can I leave it on?
Note that the glue blobs don't have the covering. In the bundle they're lined up with the plastic strips on the shingle above, on the roof of course, the blobs would be under the covering shingle tabs.
