Definition of roofing nail :

a short nail usually with a large flat head and a barbed shank used for securing roofing paper or asphalt shingles to roof boards.

Roofing nails are cleverly designed to help you do a better job. Though they vary greatly in material, size and type, all roofing nails share one helpful characteristic: a diamond‐shaped point. This point is expertly designed to keep the decking intact when it punctures through.

We'll walk you through the types, sizes and materials you may choose from when picking a roofing nail. Ultimately, it is best to refer to your building codes and   roofing manufacturer   for more specific guidance. In your building codes and international building codes, nails may be referenced as "fasteners" along with staples and screws.

Basic Types of Roofing Nails

There are basic types of roofing nails:
1. Smooth Shank

The shank of the nail is the part of the nail that punctures through the material you are nailing. Simply put, smooth shank nails have a smooth shank. They are the most basic type of roofing nail and cheaper than the other two options.

2. Ring Shank

A ring shank nail is also called an annular roofing nail or corrugated roofing nail. As its many names suggest, this type of nail has rings along the shank. They aren't connected, as they are with screws. Still, these rings give the nail extra staying power, or grip, in the shingles and sheathing.

The head diameter is typically a standard 3/8-inch for all roofing nails. A larger-size head might increase the risk of exposing part of the nail head in standard nailing locations on the shingle.

One   IKO test   found that ring shank nails have 300% more strength than smooth shank nails. So, choose these nails where performance, especially wind resistance, is a priority.

Roofing Nail Materials

You can find each of the three types of roofing nails in the three materials we list below. Whichever material you choose for your nails, remember that roofing nails are on the exterior of homes and therefore the outer surface needs to be corrosion-resistant. In fact, in some coastal regions, the building codes require the entire nail to be corrosion-resistant, not just the outer surface.

1. Steel

Steel makes for strong nails. Of course, as your nails will be on the exterior of a home, they must have rust and corrosion protection. For steel, this means stainless steel or galvanized steel. Stainless steel nails are best used for slate and ceramic roofs or asphalt shingle roofs in coastal climates.

For   asphalt roofing shingles , use galvanized nails. Galvanization adds a layer of zinc onto the steel that significantly inhibits rust and corrosion. There are two methods of galvanizing nails: hot‐dipped and electro‐galvanized. The hot‐dipped method results in a thicker layer of zinc that lasts longer, so they are preferred.

2. Copper

Copper is strong and naturally resists rust and corrosion. You may prefer to use copper roofing nails on a roof with other copper accents. Copper nails are most often used on roofs with copper flashing and accessories. However, as roofing nails will usually be hidden by the shingles above them, steel nails don't detract from the look of the roof.

3. Aluminum

Aluminum is a weaker metal than steel and copper. However, aluminum nails are still used on asphalt shingle roofing by some roofers. Aluminum nails are more prone to corrosion, as well as chemical and salt damage, than steel nails.

Length of Roofing Nails

Roofing nails are available in lengths ranging from one to two inches. Roofers seek to use just the right length of nail so that the decking (or OSB) is completely punctured by the nail. The puncture must be complete so that the whole diamond tip is past the wood.

Therefore, you have to plan out your sheathing thickness, shingle thickness and nail length carefully. If you're using typical architectural shingles and 3/8-inch-thick sheathing, you'll need 1‐inch nails. If your building codes require thicker sheathing, you'll need 1 ¼-inch nails.

When installing thicker shingles, you may need to use a longer nail in order to penetrate the OSB beneath fully. Also, when   installing ridge and hip shingles , you'll need nails that are about a half an inch longer, as they need to penetrate more shingle layers.

You may find roofing nails identified by their penny length. The penny system is an old way of classifying nails. It is represented by the letter "d." Here is a handy chart to help you find the right size of roofing nails if they are only listed in penny length.

Roofing Nail Gauge

Roof nails are available in 12-, 11- and 10-gauge. The lower the gauge number, the thicker the nail. Under most building codes in North America, 12 gauge is the minimum thickness of nails allowed on a roof. Roofing nails that are 11- or 10-gauge are also allowed by most building codes as they are thicker and sturdier. However, you may find they are more expensive.

Can I Use Screws for Roofing Shingles?

You cannot use screws for roofing shingles, only roofing nails are approved fasteners. Screws leave small gaps in the material they are driven into, and this may be enough to allow for a leak. If you were considering using screws for their extra security, consider ring shank nails instead.

What Type of Nails Should be Used with Shingles?

For best performance, you should use ring roofing nails that are made of hot‐dipped galvanized steel. You should use 12-gauge or thicker. The length of nails you use depends on the thickness of the sheathing and shingles you use.

How Many Nails per Square?

Estimating your roofing materials   is key to your success, so you'll want to know how many nails you'll use in a square. That depends on the   exposure and coverage of your shingles . With higher coverage, you'll lay down fewer shingles in a square and therefore use fewer nails. For example, when using   Cambridge ™ shingles, you'll use roughly 240 nails, because of their Advantage size. If you're installing by the High Wind Application, you'll use two more nails a shingle, so 360 nails per square.

The Cost of Roofing Nails

The cost of your roofing nails will depend on a few factors, including material, type and length. Also note that nails are sold by the pound, and if you're a professional roofer, it may benefit you to buy in bulk in order to reduce costs.

What Type of Nails for Felt/Underlayment?

Roofing felt is a type of underlayment that professionals install beneath a roof's shingles. Unlike self‐adhering underlayments, such as   ice and water protector , felt underlayment needs to be fastened in place with nails. Specifically, you'll need roofing cap nails. These have large plastic caps for heads, which help prevent water intrusion.

Don't confuse these cap nails with gasket roofing nails. Roofing nails with gaskets are intended for metal roofs. The gasket is rubber, not plastic. You want roofing nails with plastic washers for roof underlayment.

What Type of Nails for Roof Flashing?

Roofers tend to use the roofing nails they already have on hand to install flashing. You don't need to use cap nails or another special type of nail for this purpose.

What Type of Nails for Sheathing?

If you need to install new roof decking or OSB, you'll need to nail it to the roof truss. There are fewer requirements for these nails than those used to secure shingles. Common nails, or even wood screws, may be acceptable nails for OSB roof sheathing. You should check with your building code and local bylaws to confirm.

How to Fix Nail Pops in a Roof

Nails can pop above the roof surface for a number of reasons. Perhaps they were underdriven in the first place. Nails that didn't fully penetrate the sheathing may work their way up over time. Or, if a roof's decking has warped or bent, it can pull nails out of place. Whatever the cause, it's important to fix any nail pops in a roof to prevent damage.

Fixing the nails is simply a matter of removing them,   removing the shingle and installing a new shingle . Be sure you to use the correct nail length and place it properly.

Do not simply hammer the nail down, renail it in the same spot, or use the same shingle. All of these methods could allow water through the roof. For example, if you remove the nail and drive it back into the same spot, your aim won't be perfectly accurate. There will be a tiny gap on one side of the nail or the other. Even if it is imperceptible to you, water will find it.

If you use the same shingle and add the nail back in a different spot, you're leaving behind a hole where the nail once was. Some suggest you fill this hole with roofing cement, but this repair option must be done carefully to maintain the roof's water-shedding performance.

How to Seal Exposed Nails

Exposed nails are those with visible nail heads. Sometimes homeowners put in new nails when trying to   attach something on the roof . However, this is a detriment to the roof's performance.

Ideally, your roof will not have any exposed nails, with the exception of the last cap shingle (and those nails should be covered in roofing cement.) Otherwise, all new nails should be inserted so that they are covered by the shingle above them.

Can You Reuse Roofing Nails?

If you take off a shingle for repairs or take off the whole roof in   preparation for a reroofing job , you'll have a ton of roofing nails on hand. You may be tempted to reuse these to save on costs. That's a bad idea. Not only is it tedious to yank these nails out, but their zinc coating will also be worn. Plus, they may have been otherwise damaged. It's not wise to attempt to reuse them, as they may cause problems on the new roof.
