There are several reasons why homeowners might consider installing new shake roofing over existing shake roofing:
- Time and cost savings: Installing new shake roofing over existing shake roofing can save a significant amount of time and money compared to a full roof replacement. Removing the existing shake roofing can be a labor-intensive and costly process, so if it’s possible to avoid it, it can be an attractive option.
- Reduced waste: By installing new shake roofing over existing shake roofing, fewer materials end up in the landfill. This can appeal to homeowners who wish to minimize their environmental footprint.
Considerations and limitations:
While installing new shake roofing over existing shake roofing may seem like an appealing option, several considerations and limitations need to be taken into account:
- Weight considerations: Shake roofing can be relatively heavy, and installing new shake roofing over existing shake roofing adds another layer of weight to the structure. It is essential to ensure that the existing structure can support the added weight without compromising its integrity.
- Roof condition: Before deciding to install new shake roofing over existing shake roofing, it is crucial to assess the condition of the existing shake roofing. If the existing shake roofing is significantly damaged or structurally compromised, it may not be suitable as a base for the new shake roofing. In such cases, a full roof replacement is the best option.
- Roof pitch: The pitch or slope of the roof plays a role in determining whether new shake roofing can be installed over existing shake roofing. Steeper roofs are more suitable for this type of installation, as they provide better water drainage and prevent moisture issues. Shallow roofs may require a complete tear-off to ensure proper installation.
- Code regulations: Local building codes and regulations should be considered when contemplating installing new shake roofing over existing shake roofing. Some areas may require a full tear-off, while others allow for overlay installations. It is crucial to check with local authorities and ensure compliance with regulations to avoid any legal issues down the line.
While it is possible to install new shake roofing over existing shake roofing, several considerations and limitations must be carefully evaluated. Weight considerations, the condition of the existing shake roofing, roof pitch, and local code regulations are all essential factors in the decision-making process.
To make an informed decision, it is advisable to consult with a professional roofing contractor who can assess your specific situation. They will be able to provide expert advice regarding the feasibility and suitability of installing new shake roofing over existing shake roofing. Ultimately, weighing the benefits and risks will help you make the best choice for your home and budget.
