A hand nailed roof trump s a gun nailed roof any day.
Hand nail vs gun nail roofing.
Hand nailing shingles is better than using a nail gun or a pneumatic nailer because it allows the roofers to feel the nail placement and ensure optimal installation.
Some roofers think that using a nail gun delivers the same level of precision as hand nailing.
However most manufactures claim that either method is a viable option.
Hand nailing can be fast but the same man at the same skill level doing the same job will perform faster using a gun and compressor.
Most times the roofs that have been put on with a nailer all nails stay in the wood when tearing off.
Over or under pressurized nail guns can result in nails that are either driven too hard or not driven deeply enough.
I have roofing crews that can hand nail just as fast as a gun.
There just are not many shinglers that have the skill level to keep up with a man with a gun.
A hand nailed roof is hands down a better roof than using a nail gun.

A good contractor will inspect the roof sheathing after it is removed to determine if nail misses are likely to occur.
I have also torn off both hand nailed roofs and gun nailed roofs.
Hand nailed roofs most nails come out during tear off.
If this is the case hand nailing should be preferred over the use of a nail gun.
As far as it taking longer.
When you use a gun usually a third or under driven a third or over driven and a third or correct.
But it s important for these roofers to always test their tools before using them.
