Metal roofing is becoming increasingly popular as a durable and long-lasting option for homeowners. If you’re considering installing a metal roof over your existing shingles, you’ve come to the right place. In this article, we will discuss the steps involved in installing metal roofing over shingles.
First and foremost, it’s important to note that metal roofing can be installed over one layer of shingles. If you have more than one layer of shingles, they will need to be removed before installing the metal roof. Additionally, it is recommended to consult with a professional roofing contractor to ensure proper installation and adherence to local building codes.
To install metal roofing over shingles, follow these steps:
1. Begin by preparing the roof surface. This involves thoroughly cleaning the shingles to remove any debris, dirt, or loose shingles. Make sure the surface is smooth and free of any nails or protruding objects.

5. Continue installing the metal roofing panels, overlapping each panel by at least one ridge. Use metal roofing screws or nails to secure each panel in place, ensuring a tight and secure fit.
6. Install metal flashing along the edges and corners of the roof to provide additional waterproofing and protection against leaks. Secure the flashing using roofing screws or nails.
7. Finally, seal the seams and edges of the metal roof using a high-quality roofing sealant. This will further prevent water penetration and ensure a watertight roof.
In conclusion, installing metal roofing over shingles is a viable option for homeowners looking to upgrade their roofs. By following the steps outlined above and consulting with a professional, you can enjoy the benefits of a durable and long-lasting metal roof. Remember to prioritize safety and adhere to local building codes throughout the installation process.
Metal Roofing Installation Overview:
Installing metal roofing over shingles is a popular choice for homeowners looking to upgrade their roof’s durability and longevity. It is a cost-effective option that provides numerous benefits. Before proceeding with the installation process, it’s essential to understand the basic overview of installing metal roofing.
The first step in metal roofing installation is to thoroughly inspect the existing shingles. Ensure that they are in good condition and securely fastened to the roof deck. Any damaged or loose shingles should be repaired or replaced before proceeding.
Next, it’s important to measure the roof accurately to determine the amount of metal roofing materials needed. It is recommended to consult a professional metal roofing contractor for precise measurements and assistance with material selection.
After gathering the necessary materials, the old shingles should be prepared for the metal roofing installation. This involves removing any protruding nails or staples and ensuring a smooth and clean surface.
The next step is to install underlayment. Underlayment serves as a protective layer between the shingles and the metal roofing, preventing moisture from seeping through and providing additional insulation. It is essential for the overall performance and longevity of the metal roof.
Once the underlayment is properly installed, it’s time to begin placing the metal roofing panels. Start at the bottom edge of the roof and work your way up. Use appropriate fasteners, such as metal roofing screws or nails, to secure the panels to the roof deck. Follow the manufacturer’s instructions for the recommended spacing and placement of the fasteners.
As you progress with the installation, ensure that the metal roofing panels overlap correctly to provide proper water drainage. This will help prevent leaks and ensure the roof’s integrity.
Finally, it’s important to seal all seams and joints to further enhance the roof’s waterproofing capabilities. Use a high-quality sealant recommended for metal roofing, and apply it carefully to ensure a secure and watertight seal.
Throughout the metal roofing installation process, it is crucial to prioritize safety. Use proper safety equipment, such as harnesses and gloves, and work with caution on a stable and secure surface.
In summary, installing metal roofing over shingles requires careful preparation, accurate measurements, proper installation techniques, and attention to detail. By following these steps and consulting a professional if needed, homeowners can enjoy the numerous benefits of a durable and long-lasting metal roof.
3. Metal Roofing Screws vs. Nails:
When it comes to installing metal roofing over shingles, one important decision you’ll need to make is whether to use screws or nails. Both options have their pros and cons, so it’s important to weigh them before making a decision.
Metal Roofing Screws:
Screws are the most common fasteners used for metal roofing installation. They offer several advantages over nails. Firstly, screws provide better holding power, ensuring that the metal panels stay securely in place even in high winds or extreme weather conditions. They also create a tighter seal, reducing the risk of water leakage.
Another advantage of using screws is that they allow for easier removal and replacement of individual panels if necessary. This can be particularly beneficial if you need to access the underlying shingles for repairs or maintenance.
When choosing screws for your metal roofing installation, opt for self-drilling screws specifically designed for metal applications. These screws have a special coating that helps prevent corrosion, ensuring the longevity of your roof.
Metal Roofing Nails:
While screws are generally recommended for metal roofing installation, nails can still be a viable option, especially if you’re on a tight budget. Nails are typically less expensive than screws, making them a cost-effective choice.
However, nails have some drawbacks compared to screws. They may not provide as secure of a hold as screws, which can be a concern in areas prone to high winds. Additionally, nails can potentially loosen over time, leading to potential leaks or roof damage.
If you choose to use nails for your metal roofing installation, make sure to select galvanized nails that are specifically designed for use with metal roofs. Galvanized nails are coated with zinc, offering corrosion resistance and helping to extend the lifespan of your roof.
In conclusion, while both metal roofing screws and nails can be used for installing a metal roof over shingles, screws generally offer better holding power and a tighter seal. However, nails can be a more affordable option if budget is a concern. Whichever fastener you choose, make sure to follow the manufacturer’s guidelines and consult with a professional roofing contractor for proper installation techniques.
How to Seal Metal Roofing
When installing metal roofing over shingles, it is crucial to properly seal the roof to prevent any leaks or water damage. Here are the steps to effectively seal your metal roofing:
- Clean the Roof: Before applying any sealant, ensure that the roof surface is clean and free of any debris or loose materials. Use a broom or a blower to remove any dirt, dust, or leaves.
- Inspect for Damage: Check the roof for any signs of damage, such as cracks or gaps. Repair any damaged areas before proceeding with the sealing process. This will help ensure a watertight seal and prevent any further issues.
- Apply Sealant: Choose a high-quality sealant specifically designed for metal roofing. Apply the sealant using a caulking gun or a brush, depending on the type of sealant you are using. Start from the bottom of the roof and work your way up, applying a continuous bead of sealant along the seams and edges of the metal panels.
- Smooth the Sealant: To ensure proper adhesion and a professional finish, use a putty knife or a sealing tool to smooth out the applied sealant. This will help create a seamless barrier against moisture and prevent any potential leaks.
