Untreated cedar shake roofs offer a natural and rustic charm, but ensuring their longevity and stability requires careful consideration of the materials used. One common question is whether electro-galvanized (EG) nails can be safely used on untreated cedar shake roofs. In this article, we provide a concise and accurate answer to this query.
EG Nails: An Overview
EG nails, or electro-galvanized nails, are a type of fastener with a thin zinc coating applied through an electroplating process. This zinc coating provides corrosion resistance, making EG nails suitable for various indoor and outdoor applications.
Untreated Cedar Shake Roofs
Untreated cedar shake roofs are valued for their aesthetics and natural appeal. However, cedar is a softwood and can be prone to decay, especially in humid and wet conditions. This is why selecting the right fasteners is critical to ensure the longevity and stability of the roof.
Can You Use EG Nails on Untreated Cedar Shake Roof?
EG nails can be used on untreated cedar shake roofs, but it’s important to consider a few key factors:
-
Roof Environment: The local climate and weather conditions play a significant role. If your region experiences heavy rainfall or high humidity, the untreated cedar shakes may be more susceptible to decay. In such conditions, it’s advisable to use hot-dipped galvanized or stainless steel nails for enhanced durability and corrosion resistance.
-
Zinc Coating Thickness: The corrosion resistance of EG nails depends on the thickness of the zinc coating. Thicker coatings provide better protection against rust. Ensure that the EG nails you choose have an appropriate zinc coating thickness for outdoor use.
-
Maintenance: Regular maintenance of the cedar shake roof is essential. This includes inspections, cleaning, and possible treatments to protect the wood from decay.
-
Local Building Codes: Be aware of any local building codes or regulations that may specify the type of fasteners to use on cedar shake roofs. Local requirements can vary.
-
Consult a Professional: If you are uncertain about the best fastener choice for your untreated cedar shake roof, it’s advisable to consult with a roofing professional or contractor. They can provide expert advice based on the specific conditions in your area.
Conclusion
In summary, EG nails can be used on untreated cedar shake roofs, but their suitability depends on factors such as the local climate, zinc coating thickness, and maintenance practices. To ensure the longevity and stability of your cedar shake roof, consider the specific conditions in your area and, when in doubt, consult with a professional for expert guidance on the best fastener choice.
