If you’re considering a new roof for your home, you may be wondering if you can install a metal roof over your existing shingles. While it’s possible to do so, there are several factors to consider before making this choice.
David Spade of Star Roofing highlights that “One of the primary benefits of installing a metal roof over shingles is cost savings. This is because you can skip the process of removing and disposing of old shingles, which can be a significant expense. Additionally, metal roofs are durable and energy-efficient, which can result in long-term cost savings on your energy bills.”
However, there are also some considerations to keep in mind, such as the weight of the metal roof and the condition of your existing shingles.
Before making a decision, it’s important to weigh the pros and cons of installing a metal roof over shingles. By doing so, you can determine if this is the right choice for your home and budget. Let’s take a closer look at the benefits and considerations of this type of roof installation.
Evaluating the Current Roofing Condition
Before you decide to put a metal roof over shingles, it is crucial to assess the current condition of your roof. This will help you determine whether or not it is safe and appropriate to install a metal roof over shingles.
Assessing Shingles for Damage and Rot
Firstly, you should inspect your shingles for any signs of damage or rot. Look for missing or cracked shingles, as well as any signs of water damage or rot.
If your shingles are in poor condition, it is not recommended to install a metal roof over them. The metal roof will not provide a solid base, and it may not be able to support the weight of the new roof.

Understanding Local Building Codes and Permits
Secondly, you should familiarize yourself with your local building codes and permits. Installing a metal roof over shingles may require a permit, depending on where you live.
You should contact your local building department to find out what the requirements are in your area. Failure to obtain the necessary permits can result in fines and other legal issues.
You also need to ensure that the installation of a metal roof over shingles complies with local building codes. Building codes are designed to ensure that structures are safe and secure.
Installing a metal roof over shingles may require additional structural support, and you need to make sure that the installation meets all applicable building codes.
Installation Process and Considerations
Preparing the Roof for Metal Roofing Installation
Before installing a metal roof over shingles, you need to ensure that the existing shingles are in good condition. Any curled, cracked, or missing shingles should be removed and replaced before installing the metal roof.
This will ensure that the metal roof has a solid and stable base to attach to.
Once the shingles have been inspected, it is important to install an underlayment over the shingles. The underlayment will provide an extra layer of protection against moisture and will help to prevent leaks.
It is recommended to use a high-quality synthetic underlayment that is specifically designed for use with metal roofing.
Next, you should install flashing around any roof penetrations, such as chimneys and vents. This will help to prevent water from seeping into the roof and causing damage.
It is also important to ensure that the roof is properly ventilated to prevent moisture buildup and to improve energy efficiency.
Choosing the Right Metal Roofing Materials
When choosing metal roofing materials, there are several factors to consider.
The type of metal panel or shingle, the gauge of the metal, and the finish of the metal are all important considerations.
Standing seam metal panels are a popular choice for metal roofing because they provide a clean and modern look. Metal shingles are also a good option for those who want a more traditional look.
The gauge of the metal is also important, with thicker gauges providing better durability and protection against the elements.
The finish of the metal is another important consideration. A high-quality finish will provide better protection against fading and corrosion, and will also improve the energy efficiency of the roof.
Advantages and Disadvantages of Metal Roofing Over Shingles
There are several advantages to installing a metal roof over shingles. One of the biggest advantages is that it can save time and money compared to a complete roof replacement.
Metal roofing is also more durable and longer-lasting than shingles. Many metal roofs last 50 years or more.
However, there are also some disadvantages to consider. Metal roofing can be more expensive upfront, and it may require additional labor and tools to install.
Metal roofing can also be more difficult to repair if it becomes damaged, and it may not be the best choice for all types of roofs.
