Corrugated metal roof installation instructions

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. 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. Then, add screws approximately every 8 inches along the outside edge and bottom of the panel. 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 saw or tin snips for this. Start the next row above the last panel on the previous row.

Repeat steps 2 and 3 to finish the first side of the roof. Begin by cutting the peak on one side of the peaked roof. On the opposite side, you'll need to repeat this procedure yet again. Add a matching peaked ridge cap to the top of the roof.

This peak piece should be positioned on top of the roof, overlapping the metal row beneath it. As you did with the metal sheets, use washers and screws to connect them together. After you've cleaned the chimney, seal any obvious seams with roofing cement or caulk. The sealer should be allowed to dry for at least 12 hours. To extend the life of your metal roof, you may want to paint it with a clear-coat polyurethane sealer.

You may do this with a paintbrush, but many people prefer to use a paint sprayer on large roofs.

Place them directly onto purlins that are attached to the roof trusses, beginning on the outside edge. These will stop the entry of rain, wind, and pests.

Screw down the panels. Pre-drill the holes, and use 10 by 2 in Adjust the lap so that the last panel completes the coverage without making a cut lengthwise. Complete the opposite side.

Choose PVC roofing to let light in. They allow daylight to enter through them. If cost is a factor, PVC is a cheaper alternative to sheet metal.

PVC will block out the heat from the sun much more effectively than sheet metal, which will act like a radiator. Some PVC is translucent, but filters ultraviolet rays, and comes in a variety of colors. The disadvantages of PVC are that it's not as durable as sheet metal, is noisy in the rain, and can easily break off during high winds.

Pick metal roofing for greater durability. One of the strongest features of corrugated metal is its durability. Modern galvanized steel or aluminum is resistant to rust, and can easily last up to years. Metal roofing resists rot, is not susceptible to insect damage, and is non-combustible a boon in fire-prone areas.

One downside is that the metal sheets have a susceptibility to denting, both in installation and during hailstorms. Metal roofing can also be significantly more expensive than PVC.
