Installing metal roofing over asphalt shingles requires certain preparation. In some municipalities, you can only install metal roofs on homes with two or more layers of shingles. For this reason, it’s best to remove one layer of shingles before installing a metal roof. In other cases, your options may be limited by the condition of your existing shingles. Missing or deformed shingles, or even curled shingles, may prevent you from installing metal roof over shingles.

If you decide to install metal roofing over asphalt shingles, you must follow the manufacturer’s guidelines for the installation process. For example, you need to space the metal roof panels in a specific pattern depending on the orientation of the home. Also, you must use the proper fasteners and nails to attach the panels to the framing. To do this properly, you must measure the total square footage of the roof and add 10 percent to account for waste. You also need to order roofing screws in the color of your roof.

When installing metal roofing over asphalt shingles, you should remove the old shingles to prepare the surface. After the shingles have been removed, you should lay the underlayment, which will keep water from leaking onto the metal roof. Once this has been done, you can install the metal roofing over the existing roof. Make sure that you have a professional who has the necessary skills to complete the installation. A professional will make sure that the metal roof is properly installed and is water-proof.

Before installing the metal roofing over shingles, you must check local building codes. Many building officials will only permit the installation of metal roofs over a single layer of shingles. Others will approve it over two layers, although they may object to the process.
