Roofing Nashville: Can You Install a New Roof Over Your Old One?

The Pros and Cons You Should Know

One of the primary advantages of installing a new roof over your old one is the cost savings associated with skipping the removal and disposal of the old roof. However, it is important to consider the potential drawbacks before making a decision. Some of the cons of overlaying a new roof include:

1. Reduced lifespan: When you install a new roof over your old one, the lifespan of the new roof is typically shorter. Additionally, the weight of the new roof can put added strain on your home’s structure, potentially compromising its longevity.

2. Moisture issues: If there is any moisture present on your old roof, it can become trapped between the layers and lead to mold and mildew growth over time. This can cause significant damage to your roof and pose health risks to you and your family.

3. Local regulations: It’s important to note that some cities and states, including Nashville, may have regulations prohibiting the installation of a new roof over an existing one due to safety concerns. It is crucial to check with your local building department to ensure compliance with any regulations in your area.

Your Home’s Structure Matters

Before deciding to install a new roof over your old one, it is crucial to evaluate the structure of your home. The integrity of your home’s structure is a significant factor in determining whether overlaying is a viable option. It is highly recommended to have a professional roofing contractor inspect your home to assess its structural soundness and ensure that it can handle the additional weight of an overlaid roof.

The Best Roofing Materials for Overlaying

If you decide to proceed with overlaying a new roof, it is important to choose the right roofing materials. Certain materials are better suited for this type of installation. Asphalt shingles and metal roofing are two popular choices for overlay roofs. However, if your original roofing material is wood shake shingles, it is generally advisable to remove the old roof before installing the new one to avoid potential issues.

Hiring the Right Nashville Roofing Contractor

When opting for a new roof installation with overlay, it is crucial to hire a certified roofing contractor with experience in this type of installation. They will have the expertise to evaluate your old roof, identify any underlying issues, and make necessary repairs prior to installing the new roof. By choosing the right contractor, you can ensure that the overlay installation is done correctly and that your new roof will perform optimally.

Overlaying a new roof over an old one can offer advantages in terms of cost savings, but it also comes with potential drawbacks. While it eliminates the need for removing the old roof, the lifespan of the new roof is typically shorter, and moisture issues can arise. Before deciding to overlay a new roof, it is important to have your home’s structure evaluated by a professional and to comply with any local regulations. Selecting the appropriate roofing materials and hiring an experienced roofing contractor are key factors in ensuring a successful overlay installation. By considering these factors, homeowners in Nashville can make an informed decision and find a cost-effective solution for replacing their old roof.
