1. Steps To Install Corrugated Metal Roofing By following the 10 simple instructions below, you will be able to install a corrugated metal roof on your garage or shed. STEP 1: MEASURE YOUR ROOF Without getting up on the roof itself, you can get the measurements simply by measuring the length and width of the roof and then multiply these together. If the roof has a peak, then you will need to get the measurements of both sides of the roof. Also remember: you will need slightly more than the measured amount of material due to the need for overlap on the roof. The suggested overlap for a roof is 4 inches. STEP 2: BUY THE METAL PANELS Depending on the area of the roof, you can use different sized panels. You can either buy large metal panels of up to 32 feet in length and then cut them to the right size, or you can purchase pre- cut metal panels at a home improvement store that may be only 10 or 12 feet in length. If you need to cut the sheets, you can use an angle grinder, a circular saw or tin snips.

If you are installing a metal roof on a structure like a patio cover, you may not need this insulation layer. (Instead, you can just secure the metal roof directly to the wooden beams.) Cut the roofing felt to fit with a utility knife. The roofing felt will lay horizontally along the plywood deck of the roof. Attach the roofing felt with roofing staples. Make sure you overlap each layer by at least 4 inches. STEP 4: LAY AND SECURE THE FIRST METAL PANEL When laying the metal, you will need to start from the bottom corner of the roof and work across. After you have finished each row of panels, you will then need to start a new row that overlaps the old row by at least 4 inches. You can think of this process as moving across the bottom of the roof and then progressively getting higher and higher until you reach the peak. When you start with the first metal panel, position it so that it overhangs the edge by at least 4 inches. Now slide a washer onto a 1 ½-inch wood screw and use your screwdriver to secure it to the plywood of the roof. As a rule of thumb, you want it to be tight enough to hold it in place, but not so tight that you’ve dimpled the metal. Then, add screws approximately every 8 inches along the outside edge and bottom of the panel. STEP 5: COMPLETE THE FIRST ROW When it’s time to lay another metal panel, overlap the previous piece by at least one rounded corrugation. This will help to weatherproof the roof. Drive screws into the overlapped edge and bottom of each successive sheet. For the last panel of every row, you may need to cut it to size, keeping in mind the need for overlap. You can use a circular saw or tin snips for this. STEP 6: FINISH THE FIRST SIDE OF THE ROOF Start the next row above the last panel on the previous row. Overlap the row below by 4 inches. Repeat the process to finish the first side of the roof. STEP 7: LAY AND SECURE THE METAL PANELS ON THE OTHER SIDE You will then need to repeat this process on the other side of the peaked roof.

You will then need to let the cement or caulk dry for at least 12 hours. STEP 10: PAINT THE ROOF To give your metal roof even more durability, you can paint it with a clear-coat polyurethane sealer. You can use a paintbrush for this, although some people prefer to use a paint sprayer for a large roof area.
