Cedar shingles have a reputation for being finicky, but that’s only true if you treat them like drywall. The material expands and contracts with humidity, so rigid adherence to spacing, overlap, and ventilation is non-negotiable. Skimping on underlayment or using the wrong nails? You’ll pay for it in five years when the first shingle starts cupping. The pros don’t rush this project; they respect the material’s quirks. That’s why this guide emphasizes installing cedar shingles siding with an eye on longevity, not just speed. We’ll dissect the tools you’ll need (and why a cheap hammer is a false economy), the optimal weather conditions for nailing (hint: not in direct sunlight), and the hidden details—like starter strips and counter-battens—that separate a DIY disaster from a showpiece exterior.
There’s a reason historic New England clapboard homes still stand after 200 years: cedar shingles, when installed correctly, outlast most modern siding materials. But the devil is in the details. A single improperly sealed joint can compromise years of work. This isn’t just about aesthetics; it’s about protecting your largest investment. Whether you’re restoring a century-old farmhouse or cladding a modern cabin, the principles remain the same. The goal? A finish that’s not just visually stunning but structurally sound. Let’s get to the tools, techniques, and trade secrets that turn raw cedar into a lasting legacy.
The Complete Overview of How to Install Cedar Shingles Siding
Installing cedar shingles siding is a multi-stage process that demands patience and attention to detail. Unlike vinyl or fiber cement, cedar is a natural product with inherent variability—each board has its own grain, moisture content, and dimensional tolerance. This means rigid adherence to manufacturer specifications isn’t just recommended; it’s essential. The process begins long before the first shingle is lifted: with meticulous surface preparation, precise measurements, and the selection of the right fasteners. A common mistake among DIYers is treating cedar like a one-size-fits-all material, but its organic nature requires a tailored approach. For instance, the spacing between shingles must account for seasonal swelling; too tight, and they’ll buckle in winter; too loose, and they’ll gape in summer. The key is balancing aesthetics with functionality, ensuring the siding not only looks handcrafted but performs like a fortress.
Professionals often divide the installation into three critical phases: the foundation (sheathing and underlayment), the shingle application (laying, nailing, and overlapping), and the finishing touches (sealing, caulking, and trim). Each phase builds on the last, with errors in one stage cascading into problems down the line. For example, inadequate sheathing ventilation can trap moisture, leading to rot before the shingles are even installed. Meanwhile, the wrong nail gauge or pattern can cause shingles to split or loosen over time. This guide will walk you through each phase with an emphasis on the nuances that separate a mediocre job from a masterpiece. Whether you’re working on a 100-square-foot shed or a 3,000-square-foot mansion, the principles of how to install cedar shingles siding remain consistent: precision, patience, and respect for the material.
Historical Background and Evolution
The use of cedar shingles dates back to Indigenous North American tribes, who recognized its natural resistance to decay and insects. Early European settlers adopted the technique, refining it into the durable clapboard siding that defines colonial architecture. By the 19th century, cedar shingles became a staple in coastal regions, where their ability to withstand salt air and humidity made them indispensable. The material’s popularity waned in the mid-20th century with the rise of vinyl and aluminum siding, but a resurgence in sustainable building practices has brought cedar back into favor. Today, it’s prized not just for its longevity but for its eco-friendly credentials—cedar is a renewable resource that requires minimal chemical treatment compared to treated lumber.
Modern cedar shingle installation has evolved with advancements in wood science and tool technology. While the basic principles remain unchanged, contemporary methods incorporate moisture-resistant underlayments, corrosion-resistant fasteners, and specialized sealants to enhance durability. The shift toward pre-primed and pre-treated shingles has also simplified the process, reducing the need for on-site staining. Yet, despite these innovations, the core skill—handling cedar’s natural movement—remains unchanged. The material’s ability to expand and contract with temperature and humidity means installers must still adhere to strict spacing and ventilation guidelines. This historical continuity underscores why installing cedar shingles siding remains both an art and a science.
Core Mechanisms: How It Works
The structural integrity of cedar shingle siding hinges on three interconnected systems: the sheathing, the underlayment, and the shingles themselves. The sheathing—typically plywood or oriented strand board (OSB)—must be flat, dry, and properly ventilated to prevent moisture buildup. Without adequate airflow, trapped humidity can lead to mold, rot, or even insect infestations. The underlayment, often a synthetic or felt paper, acts as a secondary barrier against water intrusion, especially during heavy rain. This layer is critical because cedar shingles, while water-resistant, aren’t waterproof; their overlapping design relies on the underlayment to shed excess moisture before it penetrates the sheathing.
Once the foundation is set, the shingles are installed in staggered rows, with each row offset by at least half the width of the shingle below. This herringbone pattern ensures that water runs off rather than pooling at the joints. The nailing pattern—typically three nails per shingle, with the top nail placed just below the weather line—balances stability and flexibility. Too many nails can restrict the shingle’s natural movement, leading to cracks or splits, while too few can cause them to loosen over time. The final step, sealing the edges and joints with a high-quality caulk or primer, ensures that no gaps remain for water or pests to exploit. Understanding these mechanics is the first step in how to install cedar shingles siding correctly.
Key Benefits and Crucial Impact
Cedar shingles siding isn’t just a decorative choice—it’s a long-term investment in your home’s structural health and curb appeal. Unlike vinyl, which can yellow or crack under UV exposure, or fiber cement, which requires heavy-duty tools to install, cedar offers a timeless aesthetic that appreciates with age. Its natural insulation properties also contribute to energy efficiency, reducing heating and cooling costs over time. But the most compelling reason to choose cedar is its durability. When properly installed and maintained, cedar shingles can last 30 years or more, far outlasting many synthetic alternatives. This longevity translates to lower replacement costs and higher resale value, making it a smart choice for both historic and modern homes.
The environmental benefits of cedar shingles further solidify their appeal in today’s eco-conscious market. Sourced from sustainably managed forests, cedar requires minimal chemical treatment compared to pressure-treated lumber, reducing its carbon footprint. Additionally, cedar’s natural resistance to insects and decay eliminates the need for pesticides or fungicides, aligning with green building practices. For homeowners prioritizing sustainability without sacrificing durability, cedar shingles represent the perfect balance. The key to maximizing these benefits lies in meticulous installation—every nail, every sealant, and every ventilation gap plays a role in ensuring the siding performs as intended for decades.

Comprehensive FAQs
Q: Can I install cedar shingles over existing siding?
A: Generally, no. Existing siding must be removed to ensure proper ventilation and sheathing integrity. If you’re covering old cedar shingles, they must be in excellent condition, with no rot or mold. Otherwise, moisture will trap between layers, accelerating decay. Always consult local building codes, as some jurisdictions prohibit overlaying siding.
Q: What’s the best time of year to install cedar shingles?
A: Ideal conditions are cool (50–70°F) and dry, with low humidity. Avoid installing in direct sunlight or during extreme temperature swings, as cedar expands and contracts rapidly. Early fall or late spring are typically the best windows. Never install during freezing temperatures or heavy rain, as moisture trapped in the wood can lead to warping.
Q: How do I prevent cedar shingles from warping or cupping?
A: Warping and cupping occur when shingles absorb uneven moisture. To prevent this:
- Store shingles flat in a dry, shaded area for at least 48 hours before installation.
- Use the correct nail size (typically 1¼" ring-shank nails for cedar).
- Maintain proper spacing (⅛"–¼" between shingles and ½" at edges).
- Ensure adequate ventilation behind the sheathing (use ventilation boards or spacers).
- Avoid nailing too close to the edges, which can split the wood.
Q: Do I need to seal cedar shingles after installation?
A: Yes, sealing is crucial for long-term protection. Use a high-quality exterior wood sealant or stain designed for cedar, applied within 30 days of installation. Reapply every 3–5 years, or more frequently in high-exposure areas. Sealant prevents UV damage, water absorption, and mold growth, extending the siding’s lifespan by decades.
Q: How do I handle cedar shingles in high-wind or hurricane-prone areas?
A: For wind resistance:
- Use hurricane clips or structural screws to secure shingles to the sheathing.
- Overlap shingles by at least 1½" to prevent wind-driven rain penetration.
- Install counter-battens (horizontal strips over shingles) to add rigidity.
- Choose thicker shingles (5/16" or 3/8") for better wind resistance.
- Consult local building codes for wind-load requirements in your area.
Q: What’s the difference between cedar shingles and cedar shakes?
A: Cedar shingles are thin (typically 5/32"–3/16" thick), machine-sawn, and uniform in size. They’re lighter, easier to install, and more affordable. Cedar shakes are thicker (3/8"–1"), hand-split, and irregular in shape, offering a rustic, high-end appearance. Shakes require more maintenance (sealing every 2–3 years) but provide superior insulation and a distinctive look. Shingles are better for modern or low-maintenance builds; shakes suit historic or high-end projects.
Q: How do I clean and maintain cedar shingles long-term?
A: Regular maintenance keeps cedar shingles looking their best:
