From what I heard, shingles usually pucker due to heat. Perhaps
that one area of your roof is subjected to more heat build-up
due to poor air circulation under the roof than in other areas?

You should be concerned about this, especially in the Winter when ice can
back up on your roof and creep under the raised shingle and cause water
damage later when it thaws.

You can easily fix this by picking up a tube of asphalt cement at the
hardware store and put a bead under the puckered shingle. Normally heat
from the sun should be enough to settle the shingle into the adhesive but
you might want to consider something to add weight on top of the shingle
for a few days until the cement sets up.

Hope this helps.

I have a similar problem. The center of the shingles has lifted (as if
the edge has shrunk). This has happened over my garage, as well as the
house. The interior roof surface over the garage is exposed, so
theories about heat, moisture etc. should not apply. I suspect that
it's an inferior shingle. I am considering trying to 'roll' the
shingles flat on a hot day when they are highly flexible. If I have to
reshingle, do I need to remove these puckered shingles first?

Check to see if the cause is a roofing nail working loose. If one is pushing
the shingle up, you don't want it to push through the shingle. That's
what'll happen if you do this on a hot day.

If that's the problem, get a flat bar under the shingle and over the nail
and push it back down. Then glue down the shingle.

Nope, just cut a wedge shaped piece out of the pucker to let it lie down
flat.

I wouldn't accept that you can just glue them down or press them down and
they will stay. They are already beating gravity so your fixes will be only
a temporary fix at best. The first post about shingles around a skylight points to a improper skylight installation. Water may be leaking around the skylight and then evaporating back up thru the shingles lifting them. The house
humidity may be leaking around the skylight up thru the roof shingles.

For the garage roof, I suggest insulating the garage and ceiling including
a vapor barrier. He should check for water leakage too.

If you want to apply another layer, prudence would say you should get your
surface flat before applying the new shingles.
