Hardie siding is a popular choice for homeowners due to its durability, resistance to weather, and low maintenance. However, installing Hardie siding requires more than just the material itself – the choice of fasteners is also an important consideration. One question that often arises is whether roofing nails can be used for this purpose. While roofing nails may seem like a convenient and cost-effective option, it is crucial to determine their compatibility with Hardie siding before making a decision.
In this article, we will delve into the pros and cons of using roofing nails for Hardie siding installation and provide guidance on what types of fasteners are best suited for this type of siding.
Are Roofing Nails Suitable for Hardie Siding?
Using roofing nails for Hardie siding is not recommended. While roofing nails may seem like a convenient option due to their availability and affordability, they are not designed for use with Hardie siding and may lead to a range of problems, such as damage to the siding, potential safety hazards, and a shorter lifespan of the installation. It is recommended to use the specific type of fastener recommended by Hardie, such as corrosion-resistant nails or screws that meet specific length, type, and spacing requirements.
The Pros of Using Roofing Nails for Hardie Siding
1. Cost
Roofing nails are often cheaper than other types of fasteners, making them a tempting choice for those on a tight budget.
2. Availability
Roofing nails are widely available at most hardware stores and home improvement centers, which can be convenient for those without easy access to specialized fasteners.
3. Installation
Roofing nails can be installed quickly and easily using a nail gun, which can save time and effort during the installation process.
The Cons of Using Roofing Nails for Hardie Siding
1. Compatibility
Roofing nails are not designed for use with Hardie siding and may not meet the specific requirements for fasteners outlined by the manufacturer. This can result in damage to the siding, increased risk of moisture penetration, and other issues.
2. Safety concerns
Using roofing nails can create safety hazards for both the installer and anyone who may come into contact with the siding. Loose nails can create a tripping hazard, and improper installation can lead to the siding coming loose or falling off entirely.
3. Longevity
Roofing nails may not provide the same level of durability and longevity as specialized fasteners, which can result in a shorter lifespan for the installation and potential repairs or replacements down the line.
Hardie Siding Fastener Requirements
When it comes to fasteners for Hardie siding, it is important to follow the manufacturer’s guidelines to ensure a safe and secure installation. Here are some specific requirements for fasteners when installing Hardie siding:
1. Type of Fastener
Hardie recommends using either hot-dipped galvanized nails or screws that are specifically designed for fiber cement siding. These fasteners should be able to withstand the expansion and contraction that occurs with changes in temperature and humidity.
2. Length
The length of the fastener will depend on the thickness of the siding as well as the type of sheathing and studs that are being used. In general, nails should be long enough to penetrate at least 1 1/4 inches into the framing or sheathing material. Screws should be long enough to penetrate at least 1 inch into the framing or sheathing.
3. Head Type
The head of the fastener should be a minimum of 0.27 inches in diameter, with a flat or pan head shape. This ensures that the fastener will sit flush with the siding, without causing any distortion or damage to the material.
4. Spacing
The spacing of the fasteners will depend on the type of siding being installed. For HardiePanel siding, for example, nails should be spaced 12 inches apart on center along the perimeter and at least 18 inches apart in the field. For HardiePlank lap siding, nails should be spaced 16 inches apart on center, or as specified by local code requirements.
Other Fastener Options for Hardie Siding
1. Corrosion-Resistant Nails
These nails are specifically designed for use with Hardie siding and are made from materials that resist rust and corrosion. They come in a variety of lengths and gauges and are the most commonly used type of fastener for Hardie siding.
2. Screws
Screws can also be used to install Hardie siding, and they offer some advantages over nails. For instance, screws provide a stronger and more secure attachment, which can be particularly useful in areas that experience high winds or other extreme weather conditions. Additionally, screws can be removed and replaced more easily than nails, which can be helpful in situations where repairs or modifications are necessary.
3. Staples
Staples can be used to install Hardie siding, but they are not recommended as they may not provide sufficient holding power and can lead to premature failure of the siding.
Final Thoughts
While roofing nails may seem like a convenient and cost-effective option for installing Hardie siding, they are not recommended due to their potential to cause damage and safety hazards. Instead, it is recommended to use fasteners that are specifically designed for use with Hardie siding, such as corrosion-resistant nails or screws.
Following the manufacturer’s guidelines for length, type, and spacing is crucial for a successful and long-lasting installation that provides optimal protection and durability. In summary, choosing the right fasteners is a critical component of installing Hardie siding, and using the appropriate type of fastener will help ensure a safe, secure, and durable installation.
