asbestoa roof shingle

should the thin plastic strip on the back of the shingle be removed before installation, or does it stay in place?

Leave it on. The plastic strip only lines up with the seal-down strip WHILE THE SHINGLES ARE IN THE PACKAGE. If they seal in the package, they're ruined.

THough the manufacturers don't say anything about it, the plastic strip is in the 'nail-zone' and may be a part of the component to give the nail more holding power.

Some manufacturers even have a label stating NOT to remove it.
