Frequent Questions

Is it permissible to install new shingles over old ones in Florida according to local building codes and regulations?

In Florida, it is generally permissible to install new shingles over old ones according to local building codes and regulations. However, it is essential to comply with specific guidelines set by the Florida Building Code, as well as any specific requirements from the local authority or jurisdiction.

Installing new shingles over old ones, also known as a «roof overlay» or «re-roofing,» can be a cost-effective option that saves time and labor compared to a complete roof replacement. It allows for the new shingles to be installed directly on top of the existing ones, without removing the old shingles.

However, there are a few important considerations:

1. Building Code Requirements: Check the Florida Building Code and any relevant local building codes for specific guidelines regarding re-roofing. These codes often include requirements for the condition of the existing roof, ventilation, and maximum number of layers allowed.

2. Structural Integrity: It is crucial to ensure that the existing roof structure can support the additional weight of the new shingles. A professional roofing contractor can assess the structural integrity and determine if an overlay is a viable option.

3. Manufacturer Recommendations: Consult the manufacturer’s guidelines for the new shingles being installed. Some manufacturers may require complete removal of the existing shingles before installing their products to maintain warranty coverage.

4. Inspection and Permits: Permit requirements and inspection processes vary by location. It is essential to obtain the necessary permits and have the roof inspected to ensure compliance with building codes and regulations.

While re-roofing can be an acceptable option, it is recommended to consult a professional roofing contractor who is familiar with local building codes to evaluate the feasibility and safety of installing new shingles over old ones in your specific situation.

What are the potential drawbacks or risks of shingling over existing shingles in Florida, particularly in terms of long-term durability and weather resistance?

Shingling over existing shingles can be a cost-effective option for roof replacement, but it does come with some potential drawbacks and risks. In Florida, where weather conditions can be intense, it’s essential to evaluate the long-term durability and weather resistance of this approach.

One of the main concerns is that the added layer of shingles can increase the weight on the roof structure. This can potentially strain the roof’s structural integrity, especially if it was not designed to support multiple layers of shingles. It’s crucial to have a professional Roof Company Orlando assess the condition of the underlying roof structure before deciding to shingle over existing shingles.

Another consideration is the potential for moisture retention between the old and new shingles. If there are any existing leaks or trapped moisture beneath the original shingles, shingling over them might not address the underlying problem. Moisture trapped between layers can lead to mold, decay, and damage to the roof deck over time.

Additionally, shingling over existing shingles can conceal underlying issues such as rotted decking or damaged flashing. These problems should be addressed before installing new shingles to ensure proper long-term performance and weather resistance.

Florida’s climate also poses unique challenges. The intense heat, humidity, and frequent rainstorms can accelerate the aging process of roofing materials. Shingling over existing shingles may not provide optimal ventilation and insulation, which can contribute to increased heat transfer and reduced energy efficiency in the long run.

It’s important to note that local building codes and regulations may have specific requirements regarding the number of layers allowed on a roof. Before deciding to shingle over existing shingles, make sure to consult with a reputable Roof Company Orlando who is knowledgeable about local regulations.

In summary, while shingling over existing shingles can offer a cost-saving solution, it is essential to carefully evaluate the potential drawbacks and risks. Considerations include the structural integrity of the roof, moisture retention, underlying issues, climate factors, and compliance with local building codes. Consulting with a professional Roof Company Orlando can help ensure a thorough assessment and informed decision.

Are there any specific conditions or requirements that need to be met in order to safely and effectively shingle over old shingles in Florida, in compliance with industry standards and best practices?

When shingling over old shingles in Florida, there are certain conditions and requirements that need to be met to ensure safety and effectiveness, in compliance with industry standards and best practices:

1. Inspection: The existing roof should be thoroughly inspected to assess its overall condition. Any damage, such as rot, mold, or structural issues, should be addressed before the new shingles are installed.

2. Weight and Structure: The roof structure should be able to support the additional weight of the new shingles. Florida building codes specify the minimum design loads for roofs, including dead loads (weight of the materials) and live loads (weight of people and objects). Consult with a professional roofing contractor to determine if the roof can handle the extra layer.

3. Local Building Codes: Check with the local building department to ensure compliance with any specific regulations or guidelines regarding re-roofing over existing shingles. Some areas may have restrictions or require permits for this type of installation.

4. Manufacturer Recommendations: It is important to follow the manufacturer’s guidelines for shingle installation. Some manufacturers allow re-roofing over one layer of existing shingles, while others require a tear-off of the old shingles before installing new ones. Always check the product specifications and recommendations.

5. Roof Preparation: Before installing the new shingles, the existing roof should be cleaned and free from debris. Any loose or damaged shingles, nails, or other materials should be removed. Proper ventilation should also be ensured to prevent moisture buildup.

6. Flashing and Underlayment: Ensure that all flashing components, such as drip edges and valley flashing, are correctly installed and in good condition. Additionally, verify that the underlayment, typically a felt or synthetic material, is properly installed to provide an extra layer of protection against water infiltration.

7. Quality of Installation: Proper techniques and industry best practices should be followed during the installation process. This includes correct nailing patterns, use of appropriate fasteners, and proper alignment and overlapping of shingles. Hiring a professional roofing contractor with experience in re-roofing projects is highly recommended to ensure a high-quality installation.

Note: It is important to consult with a professional roofing contractor or building department in Orlando, Florida, for specific guidelines and requirements related to re-roofing over old shingles in the area.

In conclusion, when it comes to shingling over old shingles in Florida, it’s crucial to consider a few factors. While it may be tempting to save time and money by layering new shingles over the old ones, it’s not always the best solution. Roof Company Orlando recommends removing the old shingles to ensure a proper installation and avoid potential issues down the line. By starting with a clean slate, you can address any underlying problems and provide a solid foundation for your new roof. This approach will also allow for better ventilation and prevent excess weight on your roof structure. Ultimately, consulting with a professional roofing contractor will help you make an informed decision based on your specific situation. Trusting the expertise and experience of Roof Company Orlando will ensure the longevity and performance of your roof for years to come.
