Renailing a cedar shake roof can be a daunting task, especially when the original nails used are Electro-Galvanized (E.G.) nails. In this article, we will explore the considerations and steps involved in this process, providing clear and concise technical information for both professionals and non-technical enthusiasts.
Understanding Electro-Galvanized (E.G.) Nails
G. nails are steel nails that have been coated with a thin layer of zinc through the process of electro-galvanization. This zinc coating provides some protection against rust and corrosion but may not be sufficient for long-term use in outdoor applications, such as cedar shake roofs. Over time, exposure to the elements can cause these nails to deteriorate, leading to loose or damaged cedar shakes.
Why Renail a Cedar Shake Roof with E.G. Nails?
If your cedar shake roof was originally installed with E.G. nails, there are several compelling reasons to consider renailing it:
1. Improved Durability: Upgrading to more corrosion-resistant nails can significantly extend the lifespan of your cedar shake roof.
2. Enhanced Safety: Loose or damaged shakes can pose a safety hazard and are more susceptible to wind damage.
3. Preventing Leaks: Loose or deteriorated shakes can allow water infiltration, potentially leading to leaks and interior damage.
4. Maintenance: Renailing can be part of routine maintenance, ensuring your cedar shake roof remains in top condition.
Steps to Renail a Cedar Shake Roof
1. Assess the Roof
Start by inspecting the roof to identify loose or damaged shakes. Carefully walk the roof and mark areas that need attention.
2. Choose the Right Nails
Opt for hot-dipped galvanized or stainless steel nails, which are highly corrosion-resistant and well-suited for cedar shake roofing. These nails are available in various lengths, so choose the appropriate size based on your shakes.
3. Remove E.G. Nails
Gently pry up and remove the E.G. nails from the damaged shakes using a nail puller or a flat pry bar. Be cautious not to damage the shakes during this process.
4. Replace Shakes if Necessary
Inspect the shakes you removed. If any are damaged or split, replace them with new cedar shakes to ensure the roof’s structural integrity.
5. Install New Nails
Use a nail gun or a hammer to install the hot-dipped galvanized or stainless steel nails. Drive the nails through the shakes and into the roof deck, ensuring a secure and snug fit. Be mindful of the recommended nail placement guidelines to maintain the roof’s integrity.
6. Seal and Finish
Consider applying a sealant to the nail heads to further protect against water infiltration and improve the roof’s appearance.
Final Thoughts
Renailing a cedar shake roof originally installed with E.G. nails is a worthwhile investment in the long-term durability and safety of your roofing. Choosing the right nails and following proper installation techniques are essential for a successful project. Regular maintenance and inspection will help you detect and address issues promptly, prolonging the life of your beautiful cedar shake roof.
