Pneumatic nail guns vs.
Pros and cons of hand nailing and nail gun roofing.
Gun nailing has the potential to be less accurate.
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.
However most manufactures claim that either method is a viable option.
Using a fast nail gun can be dangerous and does not insure a good roof installation.
Gun nailing can result in nails being over driven too deep into the roof or under driven not flush with the shingle.
I have roofing crews that can hand nail just as fast as a gun.
A hand nailed roof is hands down a better roof than using a nail gun.
Since hand nailing takes a bit more time they have the chance to correct any mistakes on the spot.
A hand nailed roof trump s a gun nailed roof any day.
In roofing projects pneumatic nail guns are the most commonly used tool to drive nails into the shingles.
If the nail is driven outside that area it could impair the roof and void the manufacturer s warranty.
The key difference between the two is accuracy.
The condition of nails can be damaged by gun nailing.
Ensuring that the nails are properly placed each and every time because the head of the hammer stops flush on top of the shingles.
While air gun nailing might seem faster a well trained hand nailer can do it almost as fast.
Contractors who hand nail can feel whether or not the nail catches the wood but don t get that same feeling with a nail gun.
Driving nails with a nail gun can prove to be less than ideal.
Some roofers think that using a nail gun delivers the same level of precision as hand nailing.
