Tim,
I was having a discussion with a couple friends about installing a shingle roof. They both said the clear cellophane tape on the bottom of the shingle is to be removed before installation. I say that is an integral part of the bonding system and should be left on. What's the story?
Thanks,
Ron Tyson

Ron,
This is a fairly common question and I feel you will be surprised by the answer. Both you and your friends are wrong. The tape's sole purpose is to prevent the shingles from sticking to one another when they are stacked on top of one another in the pack. You can clearly see the pieces of tape line up with the blobs of asphalt cement on the tops of the shingles. But when you install the shingles, the cellophane tape is five inches up the roof from the dabs of cement and it does nothing to help bond one shingle to another. As I stated it is supposed to keep them apart.
You do not have to remove the tape. It is an enormous waste of time.
