Most home builders are quite surprised when they learn how to install metal roofs over asphalt shingles. They are used to seeing them used on homes made of clay or wood and are not accustomed to the durability and toughness of metal roofs. But, once a home owner installs a roof made of metal on his home, he will realize that its tough and long-lasting features come from its sturdiness and thickness. This is also one of the reasons why many home owners prefer metal roofs over other types of roofing.
The first step in learning how to install metal roofs over asphalt shingles is to find a qualified and experienced roofer. There are a number of contractors around town that would be willing to undertake this project but it helps if you get recommendations from people you know and trust. Once you have some names of contractors in your area, you can contact them and ask for quotes on getting metal roofs installed over asphalt shingles. When getting quotes from different contractors, make sure you are specific about what kind of materials they will use to cover your house. For instance, you may not want to have asphalt shingles on the top of your house if you have a gazebo or patio.
Next, you need to determine which underlayment you will use. A good contractor should be able to recommend an underlayment that suits your needs. In most cases, the usual underlayment is made from recycled rubber, but you may want to look around and see if you can find one that is made from natural rubber. Another option you have is using a thick synthetic underlayment that will help the roof to last longer. Underlayments serve as a layer between the roof and the slates so it is very important that you choose one that best meets your needs.
One other thing you need to consider when learning how to install a metal roof over asphalt shingles is whether or not you need to have two layers. Usually, this is only necessary for commercial buildings that are located in areas that get a lot of snow fall. Otherwise, there would be no need for the underlayment. If your house is located in a part of the country that does not have two layers of asphalt shingles, then you may be fine with one layer. However, in most cases, it is always better to have two layers so that the eventual failure of one of the layers does not lead to complete failure of the entire roof.
The final step in learning how to install metal roofing over asphalt shingles is to make sure the contractor you hire uses high quality steel on the project. You can do this yourself by using high grade stainless steel screws and bolts. You should also check to see if the screws are galvanized, which helps prevent corrosion. If the shingles are made from asphalt, they are generally covered in either tar or another metal that will serve as a protective coating. This coating is important because it will protect the metal underneath from the elements and keep it looking new for many years to come.
When learning how to install metal roofing over asphalt shingles, you will find that it is a relatively straightforward process. It may require you to purchase a few tools, but overall the job will not take more than an afternoon to complete. Once you learn how to install metal roofing over asphalt shingles, you may decide you want to install a metal roof over slate tiles on the roof of your home. No matter what your motivation, learning how to install metal roofing over asphalt shingles is a great way to improve the look of your roof. In addition, it is far less expensive than purchasing a new slate roof.
