Shooting Range or Someone’s Roof . . . ?

What you don’t want to hear when your new roof is being installed . . . (sounds like semi-automatic target practice at a shooting range)

Many roofing contractors cut corners so they can save a few dollars . . . using nail guns is one way to cut corners when building a roof.

Why?  Because it’s faster and faster usually means less time / labor which means lower costs for them.  But it’s not better for you, the customer.

Nail guns apply the same amount of pressure on each and every nail.

That may sound good at first but it isn’t. A nail gun has to apply the amount of pressure needed to penetrate the plywood decking and the rafter (usually a 2×4 support board on the back side of the plywood) . . . more wood requires greater force and the nail gun cannot adjust itself for when less pressure is needed.

The nail is meant to sit flush with the shingles but when it sinks in too far, it tears the fabric of the shingle and causes premature failure.  When a nail is only going through plywood (which is around 95% of a roof), it will sink in further than the nails that go into a rafter .

The result is that the nails that only go into plywood penetrate further than they should, creating a small divot or impact crater.

(Some insurance adjusters have even claimed this is a valid reason to deny a claim…we disagree but that’s a topic for another blog).

Another problem with using a nail gun is that the installers will never hold the gun at the proper angle on every nail. So instead of being flush with the roof, the nails will be over-driven and at various angles which leaves the edge of the nail head elevated like a small knife gradually working against the longevity of your new roof.
