The choice of fasteners for your roofing project is crucial to ensure durability and longevity. Cedar shakes, known for their natural beauty and weather-resistant properties, require the right type of nails to hold them securely in place. One common question is whether galvanized nails can be used for cedar shakes on a roof. In this article, we will provide a clear and concise answer.
Understanding Cedar Shakes
Cedar shakes are a popular roofing material due to their natural resistance to insects, decay, and their ability to withstand harsh weather conditions. When installing cedar shakes, it’s essential to choose the right nails to maintain the integrity of the roof.
Galvanized Nails: The Basics
Galvanized nails are steel nails that have been coated with a layer of zinc. This galvanization process provides several benefits, such as enhanced corrosion resistance. There are two main types of galvanized nails: hot-dipped and electro-galvanized.
Hot-dipped galvanized nails are coated by dipping them into molten zinc, creating a thick, protective layer. Electro-galvanized nails are coated with a thinner layer of zinc through an electroplating process.
Using Galvanized Nails with Cedar Shakes
Galvanized nails, particularly hot-dipped galvanized ones, can be used with cedar shakes on a roof with the following considerations:
1. Corrosion Resistance: Galvanized nails are known for their corrosion resistance, which is a significant advantage in roofing applications where exposure to the elements is constant. Cedar shakes can last for many years, and using galvanized nails helps ensure that the fasteners remain intact and resistant to rust.
2. Material Compatibility: Cedar is naturally acidic and can react with some metals, causing staining or corrosion. Galvanized nails are a suitable choice for cedar shakes because they resist this corrosive interaction, making them a practical and durable option.
3. Fastener Length and Gauge: The choice of nail length and gauge is important. Cedar shakes are typically thicker than asphalt shingles, so it’s crucial to use nails of an appropriate length (typically 1-1/2" to 2-1/2") and gauge to ensure a secure attachment.
Electro-Galvanized vs. Hot-Dipped Galvanized
While both types of galvanized nails offer corrosion resistance, hot-dipped galvanized nails are preferred for cedar shakes on roofs due to their thicker zinc coating. This extra protection helps the nails withstand the harsh conditions of outdoor exposure over time.
Conclusion
In summary, using galvanized nails, especially hot-dipped ones, for securing cedar shakes on a roof is a practical and reliable choice. The corrosion resistance of galvanized nails, their compatibility with cedar, and the availability of appropriate lengths and gauges make them a suitable option for your cedar shake roofing project. Ensuring the longevity and stability of your cedar shake roof begins with the right choice of fasteners, and galvanized nails fit the bill nicely.
