Hand Nailing Is FAR Superior To Nail Guns
The head of the hand nail is bigger, thus you get a stronger roof against wind force. Conversely, the head of the nail for a NAIL GUN is smaller in order to fit more nails into the coil that is reloaded repeatedly into the nail guns.
Bigger is Better.
Every nail is hammered with a hand hammer. This ensures that the nails are applied correctly; straight & flush with the shingle. Invariably, on every roof applied with a gun, 100% of the time, there will be nails that:
- Go into the shingle too far (penetrate the shingle)
- Do not go far enough where the nail will be sticking up enough to wear a leak hole
- There will be nails driven at an angle where the head cuts through the shingle because the roofer is swinging the nail gun.
