The asphalt strip is covered with a thin cellophane layer to protect
the shingles from adhering to each other during shipment and storage.
When a roof gets hot from the sun some of the tar melts out and adheres
to the shingle below it. A little asphalt goes a long ways. Removing
the cellophane is not neccesary. When shingles first came out, a roofer
would have to add a small splatering of tare under each shingle. This
was very time consuming and a real pain. It did'nt take long to figure
out they could pre-apply the asphalt, but needed the cellophane to
protect the shingles from sticking to each other for shipment and
storage. Hope this helps.
