| 2. The sealing might stop the nail from popping up in the future.
| 3. The nail is a bit farther up from the above courses tab's lower
| edge.

| anyway when installed via the directions. I would think if anything
| that the nail should go above the tar seal strip. That way any water
| that might be pulled up under the shingle by capillary action would be

| What do you think?

nail above tar strip and over each notch.
storm nailing is two nails over each slot (1 left of notch, 1right of
notch).
and one nail at each end.

the tar strip is for sealing the shingles NOT the nails.

TIP
make sure nails go thru shingle below.
if nailed above shingle below, the front of the shingle will lift. and
not seal properly.
do NOT remove plastic strip from shingles.
