Roofing Nails: Everything You Need to Know About

Roofing nails are the most fundamental fasteners in the roofing industry. They hold roofs together, support them, and prevent them from leaking. Roofing nails can also help strengthen a roof or make it last longer.

Most people, however, need to be better versed in the advanced technology that goes into choosing and using them. This blog will educate you on roofing nails, from their types and materials to size charts, to ensure your nail work is perfect.

What are Roofing Nails?

Roofing nails are one of the main components for installing shingles, underlayment, insulation boards, felt-to-wood substrates, and vinyl siding. They come in different materials but must be corrosion-resistant for exterior use.

Customers often consider buying roof sealants, underlayments, and shingles with roofing nails to ensure a reliable installation. Roofing nails have a smooth or ring shank for improved pull-through resistance.

This allows them to grip the material they're fastening better, making it less likely that the nail will slip while pounded into place. That is why they are commonly used for shingle and underlayment installation.

Types of Roofing Nails

Three types of roofing nails can be used for different applications.

Ring Shank Roofing Nails

Ring shank nails are ideal for high-wind areas, offering 300% more strength than smooth ones. They can be used for various roofing applications, including flat and pitched roofs and tiled and shingle roofs.

The ring shank design allows them to lock into place without creating gaps, making them reliable and durable. The different types of roofing nails available include smooth, coil, and ring shank nails.

Smooth shank nails are the most basic option, while ring shank coil roofing nails are threaded, creating a locking effect for added durability and reliability.

Smooth Shank Roofing Nails

Smooth shank roofing nails are specialized fasteners that attach roofing materials to a building's roof decking or sheathing. These nails have a smooth, cylindrical shaft without any thread, making driving into the decking or sheathing easier.

In addition, the head of the nail is larger than the shaft, providing a secure hold and preventing the nail from pulling through the roofing material. Smooth shank roofing nails are typically made from galvanized steel or other corrosion-resistant metals to prevent rust and extend their lifespan.

They come in various lengths and gauges, and the appropriate size for a particular roofing project depends on the type of roofing material used and the thickness of the roof decking or sheathing.

Square Cap Roofing Nails

Square cap roofing nails are specialized fasteners that attach roofing materials to a building's roof decking or sheathing. These nails have a square-shaped cap designed to provide a larger surface area for the roofing material to attach to the decking or sheathing securely.

Square cap roofing nails are typically made from galvanized steel or other corrosion-resistant metals to prevent rust and extend lifespan.

They come in various lengths and gauges, and the appropriate size for a particular roofing project depends on the type of roofing material used and the thickness of the roof decking or sheathing. 

Standard Roofing Nails

Standard roofing nails are common fasteners that attach roofing materials to a building's roof decking or sheathing. These nails have a smooth or threaded shank and a larger head, which provides a secure hold and prevents the nail from pulling through the roofing material.

Standard roofing nails are typically made from galvanized steel or other corrosion-resistant metals to prevent rust and extend lifespan.

They come in various lengths and gauges, and the appropriate size for a particular roofing project depends on the type of roofing material used and the thickness of the roof decking or sheathing.

Coil Roofing Nails

Coil roofing nails secure roof shingles, rafters, and tiles. They come in multiple sizes for a perfect fit. In addition, they can be galvanized to ensure long-lasting durability. These nails are available in ring shank or smooth shank.

Bostitch offers a variety of coil roofing nails to meet your needs. In addition, their galvanized finishes offer added durability. Whether working on a residential or commercial project, coil roofing nails will help you do the job right the first time.

Roofing Nail materials

In terms of materials, three types of roofing nails are available: steel, stainless steel, and aluminum. The three types of roofing nails are designed for different applications.

Steel

Steel materials for roofing nails must be protected from rust and corrosion so they may be coated in various coatings. One of these options is stainless steel, which is highly resistant to both forms of corrosion.

Another common option is galvanized steel, which has a protective layer of zinc coating that prevents rust formation. This coating makes it more expensive than stainless steel, but it is still a popular choice due to its durability and resistance to corrosion.

Other materials for roofing nails include aluminum, which has high strength but low weight, and steel, which is more affordable but less corrosion-resistant than other options.

Copper

Copper nails are perfect for roofs with copper accents, as they resist rust and corrosion. These nails are essential for installing slate roof tiles and copper roofing components, including copper valleys.

Roofing nails with new protein washers are suitable for installing metal or fiberglass roofing, creating a seal against water. When buying roofing nails, customers often consider purchasing roof sealants, underlayments, and shingles to create a complete roofing package.

Steel nails are a suitable alternative to copper nails for Roofing, as they won't detract from the roof's appearance since shingles will hide them. They are also more cost-effective and less harmful to the environment.

Aluminum

Aluminum Nails are commonly used for Roofing projects. They are strong, durable, and lightweight, making them an ideal choice for roofing applications. They can be used with various materials, including metal and fiberglass roofs.

However, they are weaker than copper and steel nails. In addition, the outer surface of roofing nails must be corrosion-resistant to ensure they perform their function while protecting the underlying structure.

To ensure long-term performance, roofing nails must be installed correctly to avoid potential issues such as corrosion, chemical damage, and salt damage. Aluminum nails are suitable for use with a wide range of materials, from asphalt shingles to sheet metal fabrication.

They provide superior performance at a reasonable cost and are an affordable and efficient solution for roofing projects.

Roofing Nail sizes chart

A roofing nail size chart provides information on the length and gauge of nails for different roofing materials. Nails used for shingles and underlayments should be made of corrosion-resistant materials and be of the proper gauge for the type of material being nailed.

Nail lengths vary based on the nailed material but typically fall between 8 and 12 inches. When nailing roofs, it is important to use a hammer with a round-shaped head and a nail that is the right length for the job.

Proper nailing techniques are essential for optimal shingle performance and to comply with building codes.

Choosing the right type of Roofing Nail

Before purchasing roofing nails, it is necessary to consider a few factors.

Roofing material

When installing roofing materials such as shingles or underlayments, roofing nails are vital. Properly using roofing nails will ensure that the job is completed successfully.

However, choosing the right type of roofing nail for the project depends on the type of material being installed and the type of roof being replaced. For instance, nails for installing underlayment may be thin and flat, while nails for installing shingles may be thick and round.

Therefore, choosing a nail with a head that best fits the installed material and the type of roof being replaced is important.

Climate and weather conditions

Roofing nails install roofing materials, such as shingles and underlayments. They should be corrosion-resistant to protect the integrity of the roof.

Proper nailing techniques are essential for the optimal performance of asphalt shingles and underlayments. For instance, if you are installing shingles in a coastal region, you need to use rust-resistant nails.

On the other hand, if you install them in a cold climate, you may want to use nails designed for outdoor use.

Type of roof

Roofing nails may be used to install shingles and most types of roofing underlayment. Three basic materials are available for roofing nails: steel, stainless steel, and aluminum.

Roofing nails should be corrosion-resistant and capable of holding the weight of the shingles or other installed materials. Different types of nails are available to suit specific needs.

For example, coil roofing nails can be used with roofing nail guns for rapid delivery. To ensure proper nailing techniques are used, following the instructions provided with each type of nail is essential.

Length and gauge of the Nail

Roofing nails must have the required length and gauges to fasten shingles or panels to a roof securely. This can be verified by checking the specifications of the nail, which should include a minimum 12-gauge shank and a 3/8-inch diameter head.

The type of roofing nail largely depends on the type of materials used for the project. For example, nails for asphalt shingles typically have a 16-gauge shank, while concrete ones typically have an 11-gauge shank.

The installation process for roofing nails

Preparation of the roof

Roofing nails install shingles and roofing underlayments on residential and commercial buildings. They are typically made of either steel or zinc-plated steel with one or two heads. The heads are designed to penetrate the roof surface and hold the materials in place.

To ensure that the roofing nails are strong enough to support the weight of the roof, they are typically installed with a fastener, such as a screw or bolt, above them.

Common types of roofing nails include neoprene washer roofing nails for metal or fiberglass roofs, and coastal areas may require entire nails to be corrosion-resistant.

Positioning of the nails

Roofing nails are used to install shingles and many types of roofing underlayments. They should be driven no closer than 1 inch from the edge of the shingle according to the manufacturer's specifications.

Roofing nails are ideal for installing shingles and most types of roofing underlayment, but they must be positioned correctly to ensure a secure and steady installation. In addition, nailing errors must be fixed immediately to avoid negative effects on shingle performance.

Driving the nails

Roofing nails must be hammered into place or shot with a pneumatic nail gun to ensure they stay in place. When driving nails on a metal roof, it is important to ensure that you use the correct type for the application.

For instance, roofing nails for perimeter walls require different types from those used for roof installation. Additionally, when nailing a metal roof, you must use rubber washers under the metal roofing to help prevent leaks over time.

Overdriving and underdriving

Roofing nails are used to install shingles and most roofing underlayments, including those used in installing metal or fiberglass roofing.

Nails must be driven with sufficient force to create a seal against water when installing these materials, which can be accomplished by driving them with an impact driver or by using grip-Rite® roofing nails with a neoprene washer.

Overdriven nails can be tapped in with a hammer, while underdriven nails must be removed and the hole filled with asphalt roofing cement.

Safety precautions

Roofing nails are used to install shingles and underlayments on Roofing. To ensure optimal shingle performance, using the correct type of nail for the job is crucial.

Roofing nails for exterior applications must be corrosion-resistant to withstand a home's elements and high-traffic areas. They must also be able to penetrate various materials, including cedar, cypress, and other types of wood.

For best results, follow proper nailing techniques, including quantity and location. This will help ensure a solid installation with minimal shingle damage.

Pros & Cons of Roofing Nails
