One contractor says a nail gun is better and another says hand nailing is better. Which is the preferred method?
Hand nailing allows better control and is the way to go. However, it’s usually more affordable to use a gun because hand nailing is more labour intensive. If a gun is used, the pressure should be regulated to keep from damaging the shingle by overdriving the nails. Some guns have built-in pressure regulators, and some don’t. Typically, the tank pressure should not exceed 90 psi; the gun will have the recommendation on it.
