Cedar shakes are a popular choice for roofing and siding due to their durability, natural beauty, and resistance to insect damage. However, proper installation is crucial to ensuring the longevity and performance of cedar shake products. Nailing cedar shakes too tightly is a common mistake that can lead to various issues including splitting, warping, and reduced overall performance. In this article, we will discuss whether cedar shakes can be nailed too tightly, the potential consequences of this mistake, and tips for proper installation.
Understanding the Importance of Nail Placement
Before delving into the topic of nailing cedar shakes too tightly, it is essential to understand the importance of proper nail placement. Cedar shakes are typically hand-split, resulting in variation in thickness and width. Therefore, the nails used during installation must be carefully positioned to allow for the natural expansion and contraction of the wood. The goal is to secure the shakes firmly while allowing enough freedom of movement to prevent damage.
The Consequences of Nailing Too Tightly
Nailing cedar shakes too tightly can have several negative consequences. Firstly, overdriven nails can cause the wood to split. This is particularly common when nails are placed too close to the edges of the shakes. Splitting compromises the integrity of the shakes and may lead to leaks and accelerated deterioration.
Secondly, tightly nailed shakes may experience warping or cupping. When cedar shakes are nailed too tightly, the wood is unable to move naturally in response to fluctuations in temperature and humidity. This can cause the shakes to warp, resulting in an uneven surface and potential dislodging of individual shakes.
In addition to splitting and warping, tightly nailed cedar shakes may not be able to expand and contract properly. This can lead to increased stress on the shakes and the overall system, potentially reducing the lifespan of the roof or siding. Furthermore, improper nail placement can compromise the waterproofing qualities of cedar shakes, allowing water to penetrate the structure and leading to moisture-related problems such as mildew and rot.
Best Practices for Cedar Shake Installation
To avoid nailing cedar shakes too tightly, there are several best practices to keep in mind during installation:
- Use the Right Nails: Selecting the appropriate nails is crucial. Stainless steel or hot-dipped galvanized nails are recommended to prevent corrosion and maintain longevity.
- Placement and Spacing: The shaking hand method is commonly used to ensure proper nail placement. Nails should be centered approximately 3/4″ to 1″ above the exposure line, leaving enough room for expansion and contraction. Adequate spacing between shakes is also essential to allow for movement.
- Nail Angle: Nails should be driven in at a slight angle, typically around 45 degrees. This helps to secure the shakes reliably while accommodating the natural movement of the wood.
- Consult Manufacturer Guidelines: Each cedar shake manufacturer may have specific installation guidelines to follow. It is important to consult the product instructions and adhere to any specific recommendations provided.
Nailing cedar shakes too tightly can have detrimental effects on the overall performance and longevity of the roofing or siding system. Splitting, warping, reduced waterproofing, and compromised structural integrity are all potential consequences of this installation mistake. By following best practices and being mindful of proper nail placement, cedar shake installations can ensure optimal performance and longevity, maintaining the natural beauty and durability that makes cedar shakes such a popular choice for homeowners.
