Installing Metal Roofing Over Shingles

Installing a metal roof over shingles is a great way to improve the aesthetic and structural integrity of your roof. Metal roofing is more durable and longer-lasting than traditional asphalt shingles, and it also offers superior protection against the elements. While it may seem like an intimidating prospect to tackle such a project, it is actually quite straight-forward when you know what steps to take. In this article, we will discuss how to install metal roofing over shingles in an easy, step-by-step format.

Step 1: Prepare the Roof

The first step in installing a metal roof over shingles is to prepare the roof. This involves removing the existing shingles and any nails or other debris left behind. Use a pry bar or hammer to carefully remove the shingles, being careful not to damage the underlying roof deck. Once the shingles are removed, inspect the roof deck for any signs of damage or rot. If any damage is found, it should be repaired prior to proceeding.

Step 2: Install the Underlayment

Once the roof is prepped, it is time to install the underlayment. Underlayment is a protective barrier installed between the roof deck and the metal roofing panels. It helps to protect the roof deck from moisture and provides an additional layer of protection against the elements. When installing the underlayment, make sure to overlap each piece by at least 4 inches and to secure it with nails or screws.

Step 3: Install the Metal Roofing Panels

Now it is time to install the metal roofing panels. The panels should be installed starting at the bottom of the roof and working up. It is important to keep them level as you go, and to make sure that the edges of each panel overlap the previous one. Secure the panels to the roof deck with nails or screws, making sure to space them out evenly. It is also important to make sure that the panels are adequately sealed, either with caulk or with a metal roofing sealant.

Step 4: Install the Ridge Cap

Once the metal roofing panels are in place, it is time to install the ridge cap. The ridge cap is the final piece of metal roofing that goes on the roof. It helps to seal the seams between the panels and protect the roof from water intrusion. Make sure to install the ridge cap with the appropriate sealant or caulk, and to make sure it is properly sealed. This will help to ensure a long-lasting, watertight roof.

Step 5: Clean Up the Roof

The final step in installing a metal roof over shingles is to clean up the roof. It is important to remove any nails, screws, or other debris left over from the installation. It is also important to inspect the roof for any signs of damage or rot, and to make any necessary repairs. Once the roof is clean and free of any debris, you can enjoy the beauty and protection of your new metal roof.

Conclusion

Installing a metal roof over shingles is a great way to improve the structural integrity and aesthetic of your roof. While it may seem like an intimidating prospect, it is relatively straight-forward when you know the steps to take. Make sure to prepare the roof, install the underlayment, install the metal roofing panels, install the ridge cap, and clean up the roof. Following these steps will help to ensure a long-lasting, watertight roof.
