Roof nail guns are mainstream and accepted by just about every roofing material maker out there. It is very important the guns drive the nails properly per the written directions of the shingle manufacturer, so make certain to make the effort to check out the written installation guidelines about this.

While you’re taking a look at the guidelines, take notice of the kind of nail the shingle maker suggests so you don’t void the guarantee. Understand the fastener is the lifeline of the roof material. It’s vital the fasteners last longer than the real roofing material. If the nails or fasteners rust and fail, the shingles can succumb to gravity and/or be blown away in a moderate breeze.

You need to be worried about using inferior roof nails.

When it comes to galvanized nails for roofs, the gold requirement is hot-dipped galvanized nails. These steel nails are cleaned chemically then immersed in a vat of molten zinc that in some cases consists of some lead. The molten zinc is normally between 815 and 850 degrees.

It doesn’t take long for the steel nails to rise to that temperature. When they do, the steel atoms vibrate quickly and interlock with the zinc atoms creating a zinc-steel alloy that withstands rust rather well. When the nails come out of the molten zinc, they likewise have an extra finish of pure zinc on them. Zinc does not rust, and the finishing safeguards the steel from the devastations of water. The best nails get a 2nd dipping in the molten zinc bath.

Other processes for galvanizing nails just do not provide the level of security that hot dipping does. Hot galvanizing, for instance, is a process where zinc dust or chips tumble in a hot drum with cold steel nails. This process doesn’t sufficiently warm up the steel to produce a zinc alloy on all the nails. It is, however, more affordable for nail producers.

Another process is to plate nails mechanically with zinc dust. The cold steel nails topple around with the zinc dust, tiny glass beads and a chemical. The glass beads and the chemical work to use a thin covering on zinc on the nails. Again, this process doesn’t develop the all-important alloy, and the zinc finishing can be unequal and thin.

A 3rd procedure is electroplating. Here the cold steel nails are immersed in a chemical liquid and electricity is applied to the option. The result is a thin covering of zinc on shiny nails that nearly look too good to be true. They do not have much zinc on them and, as I can confirm, they rust in short order when exposed to the elements.

Years ago, it was difficult to find hot-dipped galvanized nails that would work with nail guns. Luckily, it’s possible to obtain them for almost any roof nailer. Make certain your contract with the roofing professional defines hot-dipped galvanized nails, and focus on the minimum length required by the shingle maker.

If you’re using a thin shingle to a wood surface area and no other shingles are present, you might be able to get by with nails that are only 1 1/4 inch long. The shingle guarantees are specific about the nail length, and you desire the ideal nail so they have enough holding power to resist blowing off by strong winds.

To differentiate between nails, you probably need experience. The first thing to look at is the labeling on packages or containers the nails come in. The phrasing should state hot-dipped. If you just see the word galvanized, that’s not enough. Don’t be deceived by the words “hot galvanized” either. It’s got to state hot-dipped galvanized.

Hot-dipped galvanized nails not utilized in a nail gun are normally distinctive. Typically, they have clumps of zinc on the shaft or the finishing of zinc is rather uneven on a few of the nails. You may even find small ingots of zinc in the box or nail container. Other techniques of galvanizing leave a much smoother appearance on the nail surfaces than hot dipping.
