Now you know how to install corrugated metal roofing.
The installation of synthetic, corrugated metal sheet materials is typically a do it yourself project for those with at least some DIY experience. If you want to save money, you can purchase a few pieces of corrugated roofing materials and perform the installation on your own. Many homebuilders choose to use flat roofing materials as an option for the installation of corrugated roofing. You will need roofing felt, newspaper to fill in the joints, some aluminum screws and nails, metal sheet metal strips, and ridge caps. Before starting the installation, remember to check the weather. You may also need to invest in some roof protection accessories like roof tar paper and roof protective coatings.
It is recommended that you use flat roofing materials for this project so that you won’t need to double up on the tar paper and roofing nails you initially purchased. If you are installing over already existing corrugated metal sheets, make sure that the seams are accurately measured. This means that you must use a tape measure to determine the length of each individual panel. Measure the width as well, since you may need to cut the metal sheet further to fit across the seams. Once you have the measurements, mark the panels with a pencil so that you can properly identify which side you will be working on first.
Start by positioning all the components on the roofing panels and secure them with the roofing nails you have purchased. Start nailing the metal sheets together starting with the topmost row and working your way down the sides and bottom. Be sure to secure each piece to the adjacent piece. After you complete the bottommost row, you can start working your way up the sides and top. It may take some time, but when you learn how to install corrugated roofing panels the process becomes much faster and you won’t have to stop and stretch or otherwise work the panels.
When you learn how to install corrugated metal roofing, it is a good idea to practice at an open space with landscaping or a small garden. You can easily break the panels into sections and install one at a time. Or, you may want to try attaching three at a time. If you need help, there are many do-it-yourself books or websites that offer step-by-step instructions. Before starting your installation, be sure to line the edges of each piece of corrugated metal with roofing felt. This will act as a guide when you apply the nails.
To learn how to install corrugated metal roofing, it takes time and effort, but the result will be durable, beautiful material that can easily add charm and beauty to any structure. The greatest advantage is that it is cost effective. Metal roofing sheets are inexpensive, compared to wood, fiberglass and other materials. If you have the opportunity to remodel or repair an existing building, then the corrugated roof is a great way to spruce up the roof without a huge financial investment.
