What’s the difference between treated and untreated cedar?
Cedar shakes are a popular choice for roofing and siding due to their natural beauty, durability, and resistance to the elements. However, a critical decision homeowners face is whether to use treated or untreated cedar shakes. Understanding the differences between these options can help in making an informed decision that best suits specific needs and preferences.
Untreated Cedar Shakes
Untreated cedar shakes are made from natural cedar wood without any chemical preservatives or treatments. These shakes are valued for their organic appearance and environmental friendliness. They age gracefully, developing a silver-gray patina over time, which many homeowners find aesthetically pleasing. The natural oils in cedar provide some level of resistance to insects and decay, making untreated shakes a durable option.
However, untreated cedar shakes require regular maintenance to ensure their longevity. They are more susceptible to mold, mildew, and rot, especially in humid or rainy climates. Additionally, untreated shakes can be a fire hazard as cedar is a combustible material. Proper installation and regular cleaning can mitigate some of these issues, but they still represent a higher level of ongoing maintenance compared to treated shakes.
Treated Cedar Shakes
Treated cedar shakes undergo a process where preservatives and fire retardants are applied to the wood. This treatment enhances the durability and lifespan of the shakes by making them more resistant to moisture, insects, and decay. The treatment can also significantly reduce the risk of fire, which is particularly important in areas prone to wildfires.
There are various types of treatments available, including pressure treatments that infuse chemicals deep into the wood fibers and surface treatments that coat the exterior. These treatments help maintain the wood’s structural integrity and appearance over a longer period, reducing the need for frequent maintenance and replacement.
While treated cedar shakes offer enhanced protection, they may lose some of their natural appearance due to the chemicals used in the treatment process. Some homeowners prefer the untreated look of cedar and may find the treated shakes less aesthetically pleasing. Additionally, treated shakes can be more expensive upfront, although the reduced maintenance costs can offset this over time.
Choosing Between Treated and Untreated Cedar Shakes
The choice between treated and untreated cedar shakes largely depends on the specific requirements of the project and the homeowner’s priorities. For those seeking a more natural and environmentally friendly option with a traditional look, untreated cedar shakes may be the preferred choice. However, this option comes with the need for more diligent maintenance and a higher susceptibility to the elements.
On the other hand, treated cedar shakes are an excellent option for homeowners looking for enhanced durability and lower maintenance, especially in regions with harsh weather conditions or high fire risks. The added protection against decay, insects, and fire can provide peace of mind and potentially lower long-term costs.
Ultimately, the decision should balance aesthetic preferences, environmental considerations, maintenance capabilities, and budget. By understanding the differences between treated and untreated cedar shakes, homeowners can choose the option that best fits their needs, ensuring a beautiful and durable addition to their home.
