In roofing projects pneumatic nail guns are the most commonly used tool to drive nails into the shingles.
Hand driving nails into shingles allows for the roofer to place the nail on the proper nail line and then drive the nail in.

I see it all the time.
Gun nailing can result in nails being over driven too deep into the roof or under driven not flush with the shingle.
The depth of the nails may not be flush when a nail gun is used.

As far as it taking longer.
