Which Nails Should be Used as Roof Sheathing Nails?

Any time you are working on your roof, this is a project you need to do absolutely correctly. Something as simple as the fasteners you select for the project will significantly impact whether the finished project is high-quality and lasts for years to come. The wrong fasteners could leave it vulnerable to being wrecked by the next big storm to blow into town.

We want you to be satisfied not only with your final project but also have as easy a time as possible to complete it. That is why we want to go into as much detail as possible about selecting the right roof sheathing nails. Which nails are the right kind for the task ahead?

The Best Nails to be Used as Roof Sheathing Nails

Using the proper nails to attach sheathing will enable your roof to withstand strong winds. Traditional sheathing material typically means plywood or oriented-strand-board (OSB) panels. If you need to install new roof decking or OSB, you’ll need to nail it to the roof truss. 

Common nails are acceptable nails for OSB roof sheathing. Builders generally use 8d common nails, which are approximately 2 ½ inches long and 131/1000 inches wide in diameter. 

Types of Nails Recommended

For roof sheathing, professionals almost always recommend using nails over screws. Nails offer better flexibility and are quicker to install, making them ideal for roofing projects. Additionally, nails can accommodate the natural movement and expansion of roof materials better than screws. Here’s a breakdown of the commonly used nail types for roof sheathing:

8d Cooler Nails

An 8d cooler nail is commonly used for residential roof sheathing. The "8d" refers to an 8-penny nail, which typically measures between 2 3/8 to 2 1/2 inches in length. This size nail is perfect for securing plywood or OSB sheathing. Cooler nails have a slightly smaller shank diameter than standard nails, making them less likely to split wood when driven in.

10d Nails

For commercial applications or heavier sheathing materials, a 10d nail may be used. These nails are longer and thicker than 8d nails, offering more holding power. However, they are less commonly used for residential roofs.

Vinyl-Coated Framing Nails

Vinyl-coated framing nails are another option, especially when using a nail gun. The coating reduces friction, making it easier for the nail to penetrate the sheathing material. This can be useful for large-scale projects where speed and efficiency are key.

Screws or Nails for Roof Sheathing?

When it comes to securing roof sheathing, nails are the preferred choice over screws. While screws provide strong holding power, they are less flexible than nails and can lead to structural issues. 

Roofs are subject to constant expansion and contraction due to temperature and humidity changes. Nails allow for this natural movement without compromising the structure’s integrity. On the other hand, screws might crack the wood or break under pressure.

Nail Length for Roof Sheathing

The recommended nail length for roof sheathing is 2 3/8 to 2 1/2 inches. An 8d nail meets this requirement and is ideal for residential applications. If your sheathing is thicker or for commercial buildings, a 10d nail might be necessary. 

Ensure that the length is sufficient to penetrate through the sheathing. Also, make sure that at least 1 inch into the rafters or trusses for a secure hold.

A Few Other Considerations to Keep in Mind

Your choice in nails isn't the only big decision you'll be forced to make as you plan for and carry out the project. A few other tips to keep in mind include:

Do I Need Galvanized Nails for Roof Sheathing?

For the best performance from your fastener, you should use nails that are made of hot‐dipped galvanized steel. Be sure to use at least 12-gauge or thicker. The length of the nail you need to use will depend on the thickness of the sheathing and shingles.

Space Them Out Correctly

Nail spacing for roof sheathing depends on local building codes, which can vary based on climate and other factors. The nails should be spaced no more than six inches apart and attached 3/8 inch from the sheathing panel ends and edges. Experts also recommend using 10d box nails as spacers to estimate 1/8-inch spacing between the end of the sheathing panel and edge joints.

Don't Overdo it!

When installing the sheathing, you will want to drive the roof sheathing nails securely into the framing members. Be sure to aim the nail in the middle, rather than at the edge. This ensures that the nail is fastened securely. 

You may be tempted to overdrive the nails into the rafter, but this should be avoided. It can actually weaken the connection between the sheathing and trusses instead of strengthening it.

Nail Gun for Roof Sheathing

Using a nail gun can significantly speed up the roof sheathing process. Choose a framing nailer compatible with 8d nails, as this is the standard size for most residential roof sheathing projects. Make sure the nail gun is correctly adjusted for the length and type of nail you’re using. This is to avoid over-driving or under-driving the nails.

Selecting the right nail size for roof sheathing is a critical step in ensuring the structural integrity of your roof. In most cases, an 8d cooler nail is the best option for residential applications. On the other hand, a 10d nail may be used for heavier commercial materials. 

Galvanized nails are only necessary if you’re working with pressure-treated wood. Remember to check your local building codes for specific nail spacing requirements. Also, always use a nail gun for faster installation.
