Choosing the right nails for cedar roofing is essential for ensuring the long-term durability and performance of your roof. In this technical guide, we will provide you with accurate and concise information suitable for both technical experts and those new to roofing.

Understanding Cedar Roofing

Cedar roofing is favored for its natural beauty and ability to withstand the elements. Cedar shingles or shakes are a popular choice due to their resilience and aesthetic appeal. To install cedar roofing correctly, selecting the appropriate nails is crucial.

Key Considerations for Cedar Roofing Nails

When it comes to nailing cedar roofing, several technical details should guide your choice of fasteners:

1. Material

Stainless Steel: Stainless steel nails are the preferred choice for cedar roofing. They provide exceptional resistance to corrosion, which is essential given the cedar’s natural oils that can be damaging to many other metals. For cedar roofing, type 304 or 316 stainless steel is often recommended, as they offer the highest resistance to corrosion.

2. Length

Cedar roofing nails should be long enough to penetrate through the cedar shingle or shake, the roof deck, and into the roof trusses. A nail length of 1.5 to 2 inches is generally suitable. This length ensures a secure and lasting attachment while avoiding potential damage to the cedar material. Nails that are too short might not provide enough hold, while excessively long nails can lead to splitting of the wood.

3. Shank Type

Ring Shank or Screw Shank: For cedar roofing, it is advisable to use nails with a ring shank or screw shank design. These shanks offer increased holding power and help prevent the nails from working their way out over time. Ring shank nails have ridges on the shank that grip the wood, while screw shank nails have threads for a similar purpose. Both are effective for cedar roofing.

4. Head Style

Nails with a large, flat head are ideal for cedar roofing. This head style helps secure the shingle or shake effectively while minimizing the risk of damage. The broad head also provides an attractive finish, making it less noticeable once the cedar has aged and weathered.

5. Local Codes and Manufacturer Recommendations

Always consult local building codes and manufacturer recommendations for specific requirements when installing cedar roofing. Building codes may specify the type and length of nails, and manufacturers often provide guidelines for their products to ensure optimal performance.

Proper Installation

To ensure the cedar roofing nails perform as intended, follow these installation guidelines:

• Spacing: Nails should be spaced as recommended by the manufacturer, which typically ranges from 5 to 8 inches apart. Proper spacing ensures secure attachment and helps prevent splitting of the cedar.

• Nail Angle: Nails should be driven in at a slight angle, typically around 20-30 degrees. This angle allows for better penetration and holding power.

• Inspection: After installation, inspect the cedar roofing for any nails that may have been driven too deeply, causing damage to the cedar. Replace any damaged or improperly installed nails promptly.

Conclusion

Selecting the best nails for cedar roofing involves careful consideration of material, length, shank type, and head style. Stainless steel nails with ring or screw shanks are the preferred choice for their resistance to corrosion and superior holding power. Always consult local codes and manufacturer recommendations to ensure compliance with specific requirements. Following proper installation techniques, such as spacing and nail angle, is crucial to maintain the integrity of your cedar roofing and enjoy its natural beauty and longevity.
