What You'll Learn
Galvanized vs. Stainless Steel Nails
Choosing the right nails for cedar shake installation is critical to ensuring longevity and aesthetic appeal. Among the options, galvanized and stainless steel nails stand out, but their suitability depends on specific project needs and environmental conditions. Galvanized nails, coated with a zinc layer, offer corrosion resistance at a lower cost, making them a popular choice for budget-conscious projects. However, in coastal or highly humid areas, the zinc coating can degrade faster, potentially compromising the nail’s integrity over time. Stainless steel nails, while more expensive, provide superior corrosion resistance due to their chromium content, which forms a protective oxide layer. This makes them ideal for harsher environments where moisture and salt exposure are concerns.
When deciding between the two, consider the long-term exposure to elements. For instance, if your cedar shake siding will be in direct contact with saltwater or heavy rainfall, stainless steel nails are the safer investment. Their higher upfront cost is offset by reduced maintenance and longer lifespan. Galvanized nails, on the other hand, are sufficient for inland or less exposed areas, where the risk of corrosion is minimal. Always ensure the nails are compatible with cedar to avoid chemical reactions that could stain or damage the wood.
Installation techniques also play a role in nail selection. Stainless steel nails are harder and more brittle, requiring precise drilling to avoid bending or breakage. Galvanized nails, being softer, are more forgiving during installation but may not hold as firmly in dense cedar. For best results, use a nail gun with adjustable depth settings to ensure consistent penetration without overdriving. Pre-drilling is recommended for stainless steel, especially in colder climates where the wood may be harder.
A practical tip is to match the nail color to the cedar shake for a seamless appearance. Stainless steel nails are naturally silver, which may stand out unless painted or stained. Galvanized nails often have a darker, zinc-gray finish that blends better with untreated cedar. If aesthetics are a priority, consider using ring-shank nails, which provide better grip and are available in both materials.
In conclusion, the choice between galvanized and stainless steel nails hinges on budget, environment, and desired durability. For most homeowners, galvanized nails offer a cost-effective solution, while stainless steel nails are the premium choice for maximum protection. Assess your project’s specific demands to make an informed decision that balances performance and expense.

Proper Nail Length for Cedar Shakes
Choosing the right nail length for cedar shakes is critical to ensuring a secure, weather-resistant installation. Too short, and the nails may not penetrate the sheathing adequately, compromising the roof’s integrity. Too long, and they risk protruding through the shake, creating entry points for moisture and weakening the wood. The ideal nail length balances penetration depth with material thickness, typically ranging from 1.5 to 2 inches for standard cedar shakes. This ensures the nail anchors firmly into the roof deck without damaging the shake itself.
Analyzing the anatomy of a cedar shake reveals why nail length matters. Shakes are often 3/8 to 5/8 inch thick, with an additional 1/2 inch of roofing felt or underlayment beneath them. A 2-inch nail allows for 1 to 1.25 inches of penetration into the sheathing, providing a strong hold. Shorter nails, such as 1.5 inches, are suitable for thinner shakes or when using a double layer of underlayment, but they require precise placement to avoid under-penetration. Always measure the combined thickness of the shake, underlayment, and sheathing to determine the appropriate nail length.
Practical tips can streamline the selection process. For example, use a nail gauge or caliper to measure the shake thickness before starting the project. If in doubt, opt for a slightly longer nail and test its penetration on a scrap piece of sheathing. Additionally, consider environmental factors: in high-wind or seismic zones, longer nails (up to 2.25 inches) may be necessary to meet local building codes. Always consult manufacturer guidelines or a roofing professional for region-specific recommendations.
Comparing nail lengths highlights their impact on longevity and performance. A 1.5-inch nail, while cost-effective, may not provide sufficient hold in areas prone to extreme weather. Conversely, a 2.5-inch nail, though overkill for most installations, could be beneficial for thicker shakes or heavy-duty applications. The key is to match the nail length to the specific demands of the project, ensuring both structural integrity and aesthetic appeal. Proper nail length is not just a detail—it’s a cornerstone of a durable cedar shake roof.

Ring Shank vs. Smooth Shank Nails
Choosing between ring shank and smooth shank nails for cedar shake installation hinges on one critical factor: holding power. Cedar, a naturally resilient yet lightweight wood, demands fasteners that resist both withdrawal and lateral movement, especially in wind-prone areas. Ring shank nails, with their ridged spiral design, create a mechanical bond within the wood fibers, significantly increasing pull-out resistance compared to smooth shank nails. This makes them the preferred choice for regions with high wind loads or where building codes mandate enhanced fastening.
Smooth shank nails, while easier to drive and less likely to split cedar shakes, lack the same holding strength. Their smooth surface allows for easier penetration but relies solely on friction for grip. This can lead to loosening over time, particularly in climates with extreme temperature fluctuations that cause wood expansion and contraction. For cedar shakes, where longevity and weather resistance are paramount, the trade-off between ease of installation and long-term security often favors ring shank nails.
The decision isn’t solely about strength, however. Consider the cedar shake’s thickness and the roofing underlayment. Thicker shakes may require longer nails, and ring shank nails, due to their increased friction, can be more challenging to drive without pre-drilling. Smooth shank nails, in contrast, glide through wood more easily, reducing the risk of splitting during installation. Additionally, the type of underlayment matters: synthetic underlayments, which are more common today, provide a smoother surface that can accommodate either nail type, while felt underlayments may benefit from the added grip of ring shank nails.
For DIY installers, the choice may also come down to tools and technique. Pneumatic nail guns, when paired with ring shank nails, require careful calibration to avoid overdriving, which can damage the shake. Hand-driving ring shank nails demands more effort but offers greater control. Smooth shank nails, whether driven by hand or gun, are more forgiving in terms of force but require meticulous attention to ensure proper seating without compromising the wood.
Ultimately, the ring shank vs. smooth shank debate for cedar shakes is a balance of climate, code, and craftsmanship. In high-wind zones or where building regulations are stringent, ring shank nails provide the necessary security. For milder climates or projects prioritizing ease of installation, smooth shank nails can suffice, provided they are installed with precision. Always consult local building codes and consider the specific conditions of your project before making a decision.

Nail Corrosion Resistance for Cedar
Cedar shakes, known for their natural beauty and durability, require careful consideration when selecting nails to ensure longevity and aesthetic appeal. One critical factor often overlooked is nail corrosion resistance. Cedar, being naturally resistant to decay, deserves fasteners that match its resilience. Exposure to moisture, especially in humid climates or areas prone to rain, can accelerate corrosion in nails, leading to unsightly stains or structural compromise. Stainless steel nails are the gold standard for corrosion resistance, offering unparalleled durability in both coastal and inland environments. Their higher initial cost is offset by their ability to withstand harsh conditions without rusting, making them a wise investment for cedar shake installations.
While stainless steel nails are ideal, not all stainless steel is created equal. Type 304 stainless steel is suitable for most applications, but for coastal regions with high salinity, Type 316 stainless steel is recommended due to its superior resistance to chloride-induced corrosion. Galvanized nails, often considered a budget-friendly alternative, provide moderate corrosion resistance but are prone to eventual rusting, particularly in acidic environments. Copper nails, though naturally corrosion-resistant, can cause unsightly dark streaks on cedar due to chemical reactions, detracting from the wood’s natural beauty. Hot-dipped galvanized nails, while better than electro-galvanized, still fall short of stainless steel’s longevity.
The choice of nail material also impacts the cedar’s appearance over time. Rust stains from inferior nails can mar the wood’s surface, requiring costly maintenance or replacement. Stainless steel nails, on the other hand, remain invisible to the eye, preserving the cedar’s pristine look. For those concerned about cost, consider this: the expense of replacing corroded nails and repairing damaged shakes far exceeds the upfront investment in high-quality fasteners. Additionally, stainless steel nails maintain their integrity even as cedar expands and contracts with seasonal changes, ensuring a secure hold over decades.
Practical installation tips can further enhance corrosion resistance. Pre-drilling holes reduces the risk of splitting cedar shakes and minimizes stress on the nails, prolonging their lifespan. Using a nail gun with adjustable depth settings ensures consistent fastening without overdriving, which can weaken the wood. For added protection, apply a corrosion-resistant coating to the nails before installation, though this is no substitute for inherently resistant materials like stainless steel. Regular inspections, particularly after severe weather, can identify early signs of corrosion and allow for timely intervention.
In conclusion, prioritizing nail corrosion resistance is essential for maximizing the lifespan and beauty of cedar shakes. Stainless steel nails, particularly Type 316 for coastal areas, offer unmatched durability and aesthetic preservation. While the initial cost may be higher, the long-term savings and peace of mind make them the superior choice. By combining the right materials with proper installation techniques, homeowners can ensure their cedar shake roofs or siding remain both functional and visually stunning for generations.

Hand-Driven vs. Pneumatic Nail Guns
Choosing between hand-driven nails and pneumatic nail guns for cedar shake installation hinges on precision versus efficiency. Hand-driven nails, typically stainless steel or hot-dipped galvanized, offer meticulous control, ensuring each nail is placed and seated perfectly. This method is ideal for smaller projects or areas requiring fine detail, such as corners or intricate patterns. However, it demands physical effort and time, making it less practical for large-scale installations. Pneumatic nail guns, on the other hand, streamline the process, driving nails at a consistent depth and speed. They are best suited for expansive roofs or siding projects where time is of the essence. The key lies in balancing the need for speed with the demand for precision, as each method has its distinct advantages and limitations.
For hand-driven nails, the process involves selecting the right type—typically 1¼-inch to 1½-inch stainless steel or galvanized nails—and using a hammer to secure them. This method allows for adjustments on the fly, ensuring each cedar shake aligns perfectly with its neighbors. It’s crucial to avoid overdriving nails, as this can split the wood, or underdriving them, which compromises the shake’s hold. Hand-driven nails are also quieter, making them a better choice for noise-sensitive areas or early-morning work. However, the repetitive motion can lead to fatigue, slowing down the project and increasing the risk of errors over time.
Pneumatic nail guns, equipped with 1¼-inch to 1½-inch roofing nails, offer a faster alternative but require careful calibration. The gun’s pressure must be adjusted to ensure nails are driven flush without damaging the cedar shakes. Over-reliance on the gun’s power can lead to inconsistent results, especially on uneven surfaces. Additionally, the noise and recoil of the gun may limit its use in certain environments. Despite these drawbacks, pneumatic nail guns significantly reduce installation time, making them indispensable for large projects. Proper maintenance, such as regular oiling and nail chamber cleaning, ensures consistent performance and longevity of the tool.
The choice between hand-driven nails and pneumatic nail guns ultimately depends on the project’s scale and the installer’s priorities. For small, detail-oriented tasks, hand-driven nails provide unmatched control and precision. In contrast, pneumatic nail guns excel in large-scale applications where speed and efficiency are paramount. Combining both methods—using hand-driven nails for critical areas and pneumatic guns for the bulk of the work—can yield optimal results. Regardless of the method chosen, selecting corrosion-resistant nails is essential to ensure the longevity of the cedar shake installation, as cedar’s natural oils can accelerate rust in inferior materials.
In practice, seasoned installers often recommend starting with hand-driven nails for the first row or intricate sections, then switching to a pneumatic gun for the remainder. This hybrid approach leverages the strengths of both methods, minimizing errors while maximizing efficiency. Always pre-drill holes when using hand-driven nails to prevent splitting, especially in colder or drier climates where cedar is more brittle. For pneumatic guns, test the pressure on scrap cedar shakes to fine-tune the settings before beginning the actual installation. By understanding the nuances of each method, installers can achieve a durable, aesthetically pleasing cedar shake finish tailored to the project’s unique demands.
