Learning How to Install Metal Roofing Over Asphalt Shingles
It may seem difficult or even dangerous to learn how to install metal roofing over asphalt shingles. After all, asphalt shingles are quite heavy and you have to be very careful not to damage them by the pressure from the heavy roof panels. Moreover, asphalt shingles have shorter spans and tend to get damaged easily by high winds. However, you can learn the tricks of the trade if you really want to know how to install metal roofing over asphalt shingles.
First of all, you have to prepare the roof for installation. You have to make sure that the roof is flat and clear of obstacles like leaves and debris. The space between two adjacent roof sheets must be equal to the area of the roof. Once you have ensured that the area is square, the next step is how to install metal roofing over asphalt shingles. You need to secure the metal sheets to the roof and start welding by following instructions given in your roofing materials manual.
Asphalt shingles are more vulnerable to weather conditions compared to other materials like metal. The metal is more brittle when it is wet, and it is more susceptible to damages by rain and extreme weather conditions. If you want to learn how to install metal roofing over asphalt shingles, then you should take extra care in handling the sheet metal sheets. If you don’t want to damage them further, then make sure that you handle them properly.
You might think that installation of metal over asphalt shingles is a little difficult. But once you get to know the installation process, you will realize that it is not so. You can easily learn how to install metal roofing over asphalt shingles, even if you are new to the DIY (do-it-yourself) world. This is because the process of installation will not only make your task easier, but will also provide you with an added sense of accomplishment.
When you are learning how to install metal roofing over asphalt shingles, remember that you don’t always need to use nails or screws to attach the metal sheets. There are plenty of options for you. For instance, you can either use clips or hooks to hold the sheets in position. Metal clips are probably the easiest option. Just keep in mind that you should leave at least 4 inches of space between the metal and the roof, in order to allow ventilation.
As for hooks, you might be wondering how to install metal roofing over asphalt shingles when there are already nails in place. However, when it comes to using hooks, you will want to make sure that they are long enough to reach from the rooftop to the base of the building. You also have to make sure that they are strong enough to withstand the weight of the metal sheets. After installing them, simply use clips or hooks to attach them again.
