Not true. Maybe the tape is designed to transfer itself from the
adhesive tar strip to the shingle above it in the bundle, but it did
not on the shingles that were blown off. In other words, the tape
remained on the adhesive tar strip thus preventing adhesion.
Furthermore, many of the shingles that were not blown off can be
easily lifted. Gusts on that particular day were 50 mph and we can
expect more of that type of wind in March.


: The shingles mystery -- it pops up every three months. What IS that clear
tape on the back of shingles for?!! To remove or not to remove ... that is
the question ... answered here!

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

DEAR 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. These dabs of asphalt cement indeed are
the glue that allows the shingles to bond together once the roofing is
installed. But think for a moment. 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.

You do not have to remove the tape. That would be an enormous waste of time.
