When your shake roof nails begin to rust after the warranty period, it’s essential to understand the problem and consider the potential solutions. In this article, we’ll provide clear and concise information about why nails rust on shake roofs, how to address this issue, and what to expect post-warranty.

Understanding the Rust Issue

Causes of Rust

Shake roofs are often installed using galvanized or stainless steel nails during the warranty period. These materials are corrosion-resistant and effective in preventing rust. However, once the warranty expires, environmental factors and aging may lead to rust issues. Common causes of nail rust on shake roofs include:

• Exposure to Moisture: Shake roofs are subject to rain, snow, and humidity. Over time, the constant exposure to moisture can cause nails to rust.

• UV Exposure: The sun’s UV rays can deteriorate the protective coatings on nails, making them susceptible to rust.

• Temperature Fluctuations: Cycles of heating and cooling can contribute to the expansion and contraction of the nails, which may degrade their protective coatings.

Addressing Rust Issues

1. Inspection

Post-warranty, it’s essential to conduct regular roof inspections to identify rust issues early. Check for discolored or rusty nails, loose shakes, and any signs of water damage.

2. Replace Rusty Nails

If rust is detected, it’s advisable to replace the affected nails with new, galvanized, or stainless steel nails. These materials are resistant to rust and will provide a longer-lasting solution.

3. Coating

Consider using a suitable rust-resistant coating on the nails as an extra layer of protection. Be sure to follow the manufacturer’s recommendations for application.

4. Maintenance

Routine maintenance, such as cleaning debris and vegetation from the roof and keeping gutters clear, can help prevent excessive moisture buildup and prolong the life of the roofing nails.

Post-Warranty Expectations

After the warranty period, it’s important to understand that maintenance and occasional repairs are part of the responsibility of owning a shake roof. Rust may occur, but with prompt action and proper care, you can mitigate its impact and extend the life of your roof.

Conclusion

Addressing rust issues on shake roofs post-warranty is a common concern. Understanding the causes of rust, conducting regular inspections, replacing rusty nails with corrosion-resistant alternatives, and implementing maintenance measures can help you manage this issue effectively. While rust may be a part of your roofing journey, proactive care can ensure your shake roof continues to protect your home for years to come.
