Stainless steel nails are good for fastening tiles and slate. Galvanized roofing nails, or steel nails coated in zinc, are perfect for asphalt shingles, and they hold up well against rust. Aluminum nails should be used for surfaces made out of metal and siding.
What size roofing nails should I use?
NRCA does not recommend the use of staples for fastening asphalt shingles. Roofing nails should be round-headed, sharp-pointed 11-gauge galvanized steel or the equivalent corrosion-resistant roofing nails. Nail head sizes recommended are 3/8-inch to 7/16-inch diameter. Nail heads should be low profile, smooth and flat.
Do you need galvanized nails for roofing?
Roofing nails tend to be galvanized, a process that makes stainless steel resistant to rust by coating it in a layer of zinc, which does not rust. Galvanization is very important when it comes to roofing nails, but even here you need to be careful because there are different types of galvanization.
Are ring shank nails used for roofing?
Ring shank nails are characterized by parallel rings or “ribs” along the shanks. When driven into wood, the rings separate the wood fibers, which then push back once a rib passes through. … Ring shank nails are best used for roofing systems with soft-wood decks because they provide a better grip.
Which is better roofing nails or staples?

How long do Galvanised nails last?
A key benefit of using Hot Dip Galvanizing is its durability. Data shows that galvanizing can provide between 34 to 170 years of protection for steel.
Can roofing nails be too long?
Yes, they can. If they are too long, they will protrude through the sheathing at the roof overhang and be visible. We call these “shiners.” If they are too long over the rest of the roof, it is unimportant, and they probably have marginally greater holding power.
What does a 4/12 pitch or a 12 12 pitch mean?
Roof slopes are most commonly defined by the rise-over-run ratio. If a roof slope “rises”, say, 4 inches when measured 12 inches along the bottom of a horizontal roof truss, the roof slope is said to be 4:12; i.e., 4 inches of rise per 12 inches (one foot) of run.
Is hand-nailing a roof better?
Some roofers believe hand-nailing shingles gives them more control over the process. They can use “feel” to determine if the nail is deep enough and in the right location. Since hand-nailing takes a bit more time, they have the chance to correct any mistakes on the spot. On the other hand, labor costs will be higher.
Why is hand-nailing shingles better?
