Thanks hr(bob) and others.

It looks like I did get the fast, easy, crappy, and wrong method of hanging
the gutters. There is definitely no caulk around the screws.

I did some http://YouTube.com searching and found gutter installation videos
and they all show that when using the gutter roof hangers with straps the
straps get nailed on under the shingle -- not through the shingles.

One brand of the hangers is Amerimax Home Products 5" Mill Finish Roof
Hanger with Strap (21030). Here's a link to a photo that shows them being
mounted under the shingle:
