If you’re considering upgrading the exterior of your home, one option that may come to mind is cedar shake siding. Cedar shake siding is not only visually appealing but also durable and long-lasting. However, if your home already has existing siding, you might wonder if it’s possible to install cedar shake siding directly over it. In this article, we will delve into this question and explore the considerations and steps involved in the process.
The Importance of Preparation
Before diving into the installation process, it’s essential to understand the importance of proper preparation. Installing cedar shake siding over existing siding requires thorough inspection and addressing any underlying issues. Failure to adequately prepare the existing siding can lead to aesthetic and functional problems down the line.
Inspect the Existing Siding
Begin by inspecting the current siding. Look for signs of damage, rot, or any potential issues that could affect the installation of the new cedar shake siding. If you come across any deteriorated or rotted sections, it’s crucial to replace or repair the damaged area before moving forward with the installation. This step ensures a solid foundation for the cedar shake siding and prevents any future problems.
Cleaning and Preparing the Surface
Next, thoroughly clean the existing siding to remove any dirt, debris, or contaminants that could interfere with the installation process. Use a power washer or a hose with a high-pressure nozzle to achieve a deep clean.
Once cleaned, let the surface dry completely before proceeding. This step is crucial as moisture trapped beneath the new cedar shake siding can result in mold, mildew, or rot over time. Ensure the surface is completely dry to prevent any potential water-related issues.
The Importance of an Air Gap
When installing cedar shake siding over existing siding, it’s crucial to create an air gap between the two layers. An air gap functions as a moisture barrier and helps reduce the likelihood of moisture retention, which can lead to rot and other structural problems over time.
To create the necessary air gap, install vertical furring strips over the existing siding’s surface. These furring strips should be made of a moisture-resistant material, such as pressure-treated wood or plastic, and should be placed vertically at regular intervals across the wall.
Applying the Cedar Shake Siding
Now that the preparation work is complete, it’s time to begin the installation of the cedar shake siding.
Start by covering the furring strips with a layer of building wrap or house wrap. This water-resistant barrier further protects against moisture and acts as an additional line of defense.
Next, begin the installation of the cedar shake siding from the bottom, working your way up. Each cedar shake should overlap the one below it, ensuring proper water drainage and preventing moisture retention.
Secure each cedar shake with corrosion-resistant nails or staples. It’s important to follow the manufacturer’s instructions regarding the appropriate fasteners and their placement.
Finishing Touches
Once the cedar shake siding is in place, make sure to complete the project by considering the finishing touches. These include trim work, sealing any gaps or joints, and applying paint or stain as desired.
Additionally, regular maintenance is crucial for the longevity and appearance of cedar shake siding. This may involve periodically cleaning, inspecting for damage, and reapplying finishes to protect against weathering.
While it is possible to install cedar shake siding over existing siding, proper preparation and attention to detail are crucial. By thoroughly inspecting, cleaning, and creating an air gap, you’ll ensure a sturdy and long-lasting installation. With regular maintenance, your newly installed cedar shake siding will enhance the beauty and durability of your home’s exterior for years to come.
