The first step in installing metal roofing over asphalt shingles is to choose the right material. The most common type of metal roofing is standing seam steel, which is more expensive than other options. It is made of long panels that run vertically. In contrast, steel shingles are smaller panels laid in horizontal rows.
The material you choose must be compatible with the existing roof. You may use an underlayment to level it before you install metal roofing. Alternatively, you can build a frame out of 2x4s that supports the metal panels. You will need to measure each side of the roof, and run the frames every 24 inches. Once you’ve done this, you can install the metal panels.
Before installing metal roofing over asphalt shingles, it is important to check the condition of your existing roof. To make sure that you’re getting the most out of your investment, you should prepare the roof with framing and underlayment. Taking the time to measure and choose the right metal roofing will ensure a successful installation. Also, removing the asphalt shingles will reveal any problematic areas in the roof structure.
Aside from being an excellent investment for your home, metal roofs are environmentally friendly. They contain between 25 and 95 percent recycled materials. This means that they won’t create as much waste as shingles do, which is great news for the planet. Moreover, a metal roof will last decades, so you won’t have to worry about replacing it.
Installing metal roofing over asphalt shingles is easy, but you must ensure that you follow proper installation methods to avoid any problems. During the process, you should also check that everything is straight and that no mechanical issues are present. Also, you should check if the plywood that supports the shingle roof is good enough to support the screws. If the wood is too weak, it will be unable to hold the metal roof. This will also make your roof more vulnerable to the wind.
Before starting the process of installing metal roofing over asphalt shingles, you should check the building codes in your area. Some building codes do not allow the installation of metal roofing over asphalt shingles, so you may have to remove your existing roof first. In addition, it is important to consider the weather conditions in your area, since metal roofs can become damaged by strong storms. If you live in an area where storms occur regularly, you should consider taking out a homeowner’s insurance policy to protect your property.
Installing metal roofing over asphalt shingles will save you time and money. It will save you from having to remove your current shingle roof, which will involve countless hours of labor. In addition, metal roofing will last many decades longer than the asphalt-shingle roof.
