It is conceivable that when the shingles were removed from the
packaging at the time of installation, the cellophane strip, instead
of sticking to the underside of the shingle above in the packaging,
stuck to the tar strip on the shingle below. This scenario requires a
manufacturing defect and a really clueless installer.
