true…all of that. In this particular case, nothing shady at all. Just a case of a contractor that doesn’t know his trade. The agent contacted a different roofer after all this feedback.

And what was their opinion?
No.
The cellophane will not melt, it’s not like that.
If cellophane is in the way of the tar strip, it must be removed, as cellophane will never stick.
Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.
Once shingles are installed, the cellophane strips no longer align with the adhesive, and the cellophane does not have to be removed . In fact, it should not be removed because it often carries printed information about the shingles.
This asphalt shingle adhesive glue-strip is intended to bond to the three tabs of the next shingles nailed atop of this one when the roof is later warmed by sunlight. The success with which asphalt shingles bond together as the glue strip is heated by sun exposure is a factor in protecting roof shingles from wind-damage and blow-off.
Kinda hard to do with cellophane atop glue strip unless degraded with heat. Nail shingles for well over 10 years.
The cellophane tape aligns with the adhesive strip when the shingles are oriented a certain way inside a package of shingles. The cellophane tape is designed to isolate the adhesive strip of one shingle from sticking to another shingle inside the shingle package. When the package is opened and the shingles are peeled apart, the cellophane tape is supposed to stick to the shingle face without the adhesive strip. This means, normally, the cellophane tape does not need to be removed during installation because the new orientation of shingles in the installation(different from inside the package) causes the cellophane tape to be out of alignment with the adhesive strip of another shingle(so the shingle can stick).
However, we don’t live in a perfect world. Occasionally, inside the shingle package, the bond between the cellophane tape and adhesive strip is stronger than the bond between the cellophane tape and the other shingle. This causes the cellophane tape to stick to the adhesive strip instead. When the shingle with the adhesive strip blocked by the cellophane strip gets installed, it does not stick to the other shingle. This is wind damage waiting to happen, so either the cellophane tape must be removed or the shingle replaced. This also happens occasionally with the first or last piece of shingle in the package because the shingle wrapper also gets stuck to the adhesive strip too, causing the same problem.

It amazes me as to how much you guys can talk about flippin’ adhesive strips.
Yep. I did an inspection back in sept. On a brand new home, and about 1/3rd of the shingles had the cellophane over the tar strips.
Well, the builder didn’t fix it right away, and about a week later, hurricane Ian came through, and ripped half the roof off.
