OK. If I (and the OP and his neighbor) were "wrong" about removing the
tape, then I cry "Mia Culpa"!

But I've seen construction industry manufacturers etc include all
manner of strange, weird, and sometimes flat-out crazy stuff in
their instructions ...

So I gotta ask the shingle-cognoscenti some simple questions:

1.) Why do they put the tar strip on the bottom of the shingle
(if not to allow bonding with other shingles on install)?

2.) Given that the plastic tape over the tar strip is to
prevent bonding -prior- to install, why wouldn't one
remove the tape -at- install time to promote bonding???

Is not my impression that shingles are designed to flap in
the wind. Is my impression that they are designed to fasten
to the outer roof -and- to bond together.

Absolutely.

They don't put the tar strip on the bottom, they put it half way up just
over where the tabs are joined together.

Becuase the plastic strip is also in the middle of the shingle, so that
when they're stacked neatly, but you don't apply them to the roof like
that, you spread them out, and the tar strip then is hitting a place on
the shingle where the plastic ain't and you get fine adhesion.

Correct, and unless you apply them to the roof with a 1" reveal or less,
you're going to get that adhesion. The only exception to that would be if
the pitch is so steep that you don't have enough pressure on the seal
strips in which case the mfg recomends applying adhesive.

Removing the plastic strips is both a waste of time and possibly going to
damage the shingles as they're not designed to have that part removed.

Mea Culpa. I should've reviewed shingle construction and
application before responding.

> 1.) Remove the tape.

Where do you get this info from (aside from your beleif)?

The manufacturer says leave it on in their instructions. The tape itself
has do not remove stamped right on it. I have never done it (because I can
read and follow instructions). I have NEVER seen ANY pro remove it. The
shingles are picked from the stack, dropped in place (if you're real good)
and pop-pop-pop-pop (6 pops for mansard or high wind areas).

I'd worry more about the residual radioactivity in the shingles. Tom
