Copper or stainless steel nails are recommended for slate roofs. The nails should have a wide, flat head and be 1-1/2 inches long.

Rubber roofs

Rubber roofs are typically installed with roofing screws rather than nails.

Copper roofs

Copper roofs are typically installed with copper nails. The nails should be 1-1/2 to 2 inches long and have a large head.

Metal roofs

Screws are typically used to install metal roofs rather than nails. However, if nails are used, they should be galvanized, have a large head, and be at least 1-1/2 inches long.

Slate shingles

Copper nails are recommended for slate shingles. The nails should be 1-1/2 to 2 inches long and have a wide, flat head.

Laminate shingles

1 inch to 1-1/4 inch roofing nails are typically used to install laminate shingles.

Wood shake shingles

Stainless steel or hot-dipped galvanized nails with a ring shank are recommended for wood shake shingles. Nails should be 1-3/4 to 2 inches long.

Cement shingles

Cement shingles are typically installed with roofing screws rather than nails.

How to choose the right roofing nails

Step 1: Determine the type of roof you have

Different types of roofs require different types of roofing nails. Consider the material of your roof, such as asphalt shingles, wood shakes, or metal panels, and look for nails that are appropriate for that material.

Step 2: Consider the size of the nail

The length and gauge of the nail are also important factors to consider. The size of the nail should be appropriate for the thickness of the roofing material being used. Using nails that are too short or too thin can result in inadequate attachment and an increased risk of damage or failure.

Step 3: Choose the right material

Roofing nails are available in various materials, including stainless steel, galvanized steel, aluminum, and copper. Each material has its own unique benefits and drawbacks, such as cost, durability, and resistance to corrosion. Consider the climate and environmental conditions in your area when choosing the right material.

Step 4:Think about the long-term

Investing in high-quality roofing nails can save you money in the long run. Cheap or low-quality nails may be more affordable upfront but can result in costly repairs or replacement down the line. Look for roofing nails that are designed to withstand the elements and last for many years.

Step 5: Look for a reputable brand

Choosing a reputable brand for your roofing nails can ensure that you are getting a high-quality product that has been tested and proven to work effectively. Look for a brand that is well-known in the industry and has a reputation for quality and reliability.

Basic types of roofing nails

Ring shank: Ring shank roofing nails have a textured shaft with small rings that run perpendicular to the nail’s axis. They come in various lengths, ranging from 3/4 inch to 2 inches, and gauges, typically 12, 11, or 10. The head of the nail is typically large and flat with a diameter of around 7/16 inch to 1/2 inch.
Smooth shank: Smooth shank roofing nails have a straight, smooth shaft with no texture. They also come in various lengths and gauges, typically ranging from 3/4 inch to 2 inches in length and 12, 11, or 10 in gauge. The head of the nail is typically smaller than that of a ring shank nail, with a diameter of around 3/8 inch.
Square cap: Square cap roofing nails have a large, flat head that is typically made of galvanized steel or aluminum. The head of the nail measures around 3/8 inch to 7/16 inch on each side, making it square-shaped. The shank of the nail is typically smooth or ringed, with a length of around 1-1/2 inches.

Screw shank: Screw shank roofing nails have a spiral, threaded shaft that provides excellent holding power. The thread creates a screw-like effect that grips the wood, holding the nail securely in place. They come in various lengths, typically ranging from 1-1/2 inches to 3 inches, and gauges, typically 11 or 10. The head of the nail is typically flat with a diameter of around 7/16 inch to 1/2 inch.

Can roofing nails be too long?

Yes, roofing nails can be too long. Using nails that are too long can lead to several problems, including:

Damage to the roofing material: If the nail is too long, it can penetrate through the roofing material and into the roof deck or framing below, causing damage to the material and potentially compromising the integrity of the roof.

Increased risk of leaks: If the nail penetrates too deeply into the roof deck or framing, it can create holes or gaps that can allow water to seep into the roof and cause leaks.
Reduced holding power: Using nails that are too long can reduce the holding power of the nail, as the excess length can prevent the nail from being driven in fully and securely.

What to do if you installed sizes over roof with the wrong size roofing nails

Assess the damage: Check the roofing material and roof deck to determine if there is any damage caused by using the wrong size nails. Look for signs of shifting or movement in the roofing material, as well as any holes or gaps that may have been created.

Remove the incorrect nails: If you have used nails that are too long or too short, carefully remove them and replace them with nails that are the correct size -nd length for the roofing material.
Add additional nails: In some cases, adding additional nails to the roof may be necessary to provide additional support and holding power. Be sure to follow the manufacturer’s recommendations for the appropriate number of nails for your specific roofing material and application.
Seal any gaps: If there are any gaps or holes in the roofing material caused by the incorrect nails, be sure to seal them with roofing sealant or another appropriate material to prevent water from seeping into the roof and causing leaks.

Consider seeking professional help: If you are unsure about how to properly address the issue or if there is significant damage to the roof, it’s a good idea to seek the help of a professional roofer to assess and repair the damage. They can help ensure that the roof is properly repaired and that it will provide long-lasting protection for your home.

What type of material are roofing nails usually made from?

Roofing nails can be made from various materials, but the most commonly used materials are galvanized steel, stainless steel, aluminum, and copper.

Galvanized steel roofing nails are the most commonly used type of roofing nails. They are coated with a layer of zinc, which helps to protect them from rust and corrosion.

Stainless steel roofing nails are another popular option. They are more expensive than galvanized steel nails, but they are also more durable and resistant to rust and corrosion.
Aluminum roofing nails are lightweight and also resistant to rust and corrosion. However, they are not as strong as steel nails and may not be suitable for all types of roofing materials.
Copper roofing nails are also available, but they are typically more expensive than other types of roofing nails. Copper nails are often used in roofing applications where appearance is important, such as on historic or high-end homes.

What is the length of a typical roofing nail?

In general, roofing nails can range in length from about 3/4 inch to 2 inches.

For example, asphalt shingles typically require roofing nails that are around 1 inch in length, while thicker sheathing materials may require longer nails, such as 1 1/4 inch or 1 1/2 inch nails.

What is the diameter of a typical roofing nail?

The diameter of a typical roofing nail can vary depending on the type and size of the nail. However, roofing nails typically have a diameter between 11 and 12 gauge.

What is the typical gauge of a roofing nail?

Gauge is a measurement of the thickness of the nail’s shank, or the part of the nail that is driven into the roof. The higher the gauge number, the thinner the shank of the nail. For example, an 11-gauge nail is thicker and stronger than a 12-gauge nail.

How to hide roofing nails

Overlapping shingles: One common method of hiding roofing nails is to overlap the shingles. By overlapping the shingles, the nails can be covered by the shingles above them. This technique is commonly used with asphalt shingles and can be effective in hiding the nails.
Using adhesive: Another method of hiding roofing nails is to use adhesive instead of nails. This technique is commonly used with metal roofing and involves applying an adhesive to the underside of the metal panels and then securing them to the roof deck. This can create a seamless look without visible nails.

Using color-matched roofing nails: Another option is to use color-matched roofing nails that blend in with the roofing material. For example, if you have a cedar shake roof, you can use color-matched cedar shake nails to blend in with the roofing material and make the nails less noticeable.
Painting the nails: If none of the above options work, you can also consider painting the roofing nails to match the color of the roofing material. This can be a time-consuming process, but it can be effective in hiding the nails and improving the overall appearance of the roof.

What is the difference between shank and screw roofing nails?

The main difference between shank and screw roofing nails is the shape of their shank.

Shank roofing nails have a smooth or ringed shank, while screw roofing nails have a twisted, helical shank that provides superior holding power.

Screw roofing nails are generally more expensive than shank roofing nails.

What type of fasteners should you use for my asphalt shingle roof?

For asphalt shingle roofs, it is recommended to use galvanized steel roofing nails with a shank diameter of 11 or 12 gauge and a length of at least 1 1/4 inches.

The shank should be smooth or have rings to provide better holding power. It’s important to use the fasteners the manufacturer suggests to make sure the roof isn’t damaged and to make sure the job is done right.

What is the corrosion resistance of roofing nails?

The corrosion resistance of roofing nails depends on the material they are made from.

Aluminum roofing nails are very resistant to corrosion. Stainless steel roofing nails are also resistant to corrosion, but they can be more expensive.

Galvanized steel nails are also commonly used for roofing and provide good corrosion resistance.

How often should you check my roofing nails for rust or corrosion?

It is recommended to inspect your roofing nails for rust or corrosion at least once a year, especially before the rainy season.

This will make sure that your roof stays in good shape and that the nails keep giving it enough support and protection from wind and rain.

What type of nails are needed for sheathing?

For sheathing, it’s recommended to use ring-shanked nails with a length of at least 1-1/2 inches and a diameter of 6 d or 8 d.

These nails are designed to provide a strong and secure hold for the sheathing material, and they are less likely to work their way loose over time.

It’s important to follow the manufacturer’s recommendations for the type and size of nails to use with your specific sheathing material, as using the wrong type of nail can compromise the integrity of the roof.
