Installing cedar siding can enhance the beauty and durability of your home’s exterior. One common question that arises during installation is whether to place the nails on the top or bottom of the siding boards. In this article, we will provide you with a clear and concise explanation of where to position your nails when working with cedar siding, ensuring that the information is accessible to both technical and non-technical readers.

Understanding Cedar Siding:

Cedar siding is a popular choice due to its natural beauty, resistance to decay, and durability. It consists of horizontal boards that overlap, creating an appealing and weather-resistant façade for homes. The placement of nails is critical to the overall performance and aesthetics of the installation.

Top or Bottom: Where to Place Cedar Siding Nails?

The choice of whether to place the nails on the top or bottom of cedar siding boards depends on several factors. Let’s break it down:

1. Nailing on the Top:

2. Aesthetics: Placing nails on the top of the boards results in a cleaner and more visually appealing finish. The nail heads are hidden beneath the overlap of the board above, providing a seamless look.

3. Weather Resistance: When you nail from the top, the overlap of the board above prevents water from seeping into the siding, offering enhanced weather resistance.

4. Tradition: This method is traditionally used in cedar siding installations and is preferred for its timeless appearance.

5. Nailing on the Bottom:

6. Accessibility: Nailing on the bottom may be more accessible and easier for some installers, especially if they are using a ladder or reaching upwards.

7. Speed: Some installers argue that nailing from the bottom can be a faster method, as it doesn’t require as much precision when it comes to aligning the nails.

However, it’s essential to understand that whichever method you choose, the key is to ensure that the nails are placed in a consistent and secure manner. The precise location of the nails along the siding boards matters more than whether they are on the top or bottom.

Technical Details to Consider:

1. Nail Selection: Use corrosion-resistant nails, such as stainless steel or hot-dipped galvanized nails, designed for outdoor use. The length of the nails should be sufficient to penetrate the siding, sheathing, and into the framing by at least 1 1/2 inches.

2. Spacing: Space the nails approximately 1 inch above the overlap point of the siding boards. For a secure installation, nails should be spaced 16 to 24 inches apart, both horizontally and vertically.

3. Angle and Technique: Insert nails at a slight angle, aiming for the sheathing or framing. Ensure the nail heads are countersunk just below the surface of the siding for a flush finish.

Conclusion:

When it comes to the placement of nails in cedar siding, you have the flexibility to choose between the top or bottom. Each method has its advantages, but the key is to be consistent and precise in your placement. Use the right nails, maintain proper spacing, and ensure the nails are securely driven to provide a durable and visually appealing cedar siding installation. Always prioritize safety, and consult the manufacturer’s recommendations for the specific siding product you are using for additional guidance.
