How to Install Metal Roofing Over Shingles

If you’re wondering how to install metal roofing over shingles, you’ve come to the right place. Although it’s not a DIY project, the steps outlined below will provide you with the necessary tools to complete the project successfully. Before you begin, make sure you have a thorough understanding of local building codes. Depending on your city, you may not be allowed to install metal roofing over shingles. If you’re not sure about your city’s rules and regulations, you can always hire a professional to install your new roof.

When installing metal roofing over shingles, it is important to follow instructions. The first step is removing the old shingles. This process is important because it requires some special tools. This will ensure that you have a flat surface, and you’ll need a ladder to reach the roof. It’s also helpful to remove old shingles before beginning. This will help protect the new roofing. In addition, it will reduce the amount of noise that your roof is subjected to when it rains.

Before installing the new metal roofing, you need to measure the area of the roof and determine the slope. You’ll need to use a carpenter’s level and a tape measure to get an accurate measurement. The length of the roof divided by twelve will be the slope. Next, multiply the area by the slope to get the square footage of the roof. After determining the square footage, you can order the metal roofing panels. Be sure to leave room between the old shingles and the new metal roofing.

Then, it’s time to add underlayment. This will help prevent the new metal roofing from abrasion and damage from UV rays. An underlayment is also essential to protect the new roof from dew point and abrasion. This will allow for quick evaporation of any water that may have collected underneath. You should also install purlins on top of the old roof deck. After the old roof has been removed, you can start attaching the metal roofing panels to it. Then, you can paint the roof with a fresh coat of paint to give it a new look.

When you’re ready to install metal roofing, you’ll need to prepare the roof deck and the attic. The attic temperature will rise, which can lead to condensation. In the long run, this can cause corrosion to the metal. It also affects the wood underneath. By using an underlayment, you’ll prevent any rusting of the metal. This way, you’ll protect your new roof from damage and still have a beautiful roof.
