All,

I just had the roof redone, and am seeing that some shingles have air
pockets underneath. My thought is that each sheet of shingle should
be fastened to the one beneath, without void. It seems like I have 3
feet of adhesion, .5 feet lifted off (about 1 inch off), and another
3 feet of adhesion. Is this normal? Is each shingle sheet expected
to adhere completely to the one below? Any advice would be
appreciated.


What do you mean by 'shingle sheet'? Shingles are normally much smaller
than the dimensions you've listed.
