How to put up corragated roofing.

To install corrugated roofing start by cutting your panels to length with an angle grinder. Continue adding panels until the roof is covered. Insert about 20 nails into the humps of the ridges spread equally throughout the panel. The silicone will spread and adhere creating a seal.

You may need to cut panels to fit angles using a circular saw with a metal saw blade. Metal roofing is also available in the form of shingles. Using galvanized nails attach the moldings. Lay the roofing felt.

Step 4 line up the second sheet overlapping the first by one ridge and install it in the same manner. Next pre drill holes on the end and side ridges of the panels spacing the holes 6 to 8 inches apart. Continue this process until all the panels are safely affixed to the ceiling. Buy the metal panels.

The screws should be fastened at least 1 inch deep into the beams. The corrugation should run up the roof toward the ridge. Line up the first panel at the bottom corner of the roof near the lip and hammer it in place with 3 inch metal roofing nails. Use the rounded molding strips on the vertical rafters and the corrugated ones on the horizontal cross braces.

Attach the moldings using galvanized nails to prevent rusting in case of any leaks. For a secure and attractive finish you should use molding strips on top of the rafters. Beginning at the outside edge of your roof place each panel directly onto the purlins that are attached to the roof trusses. Be sure before you fasten the roofing itself however that you lay down closure strips underneath where the screws will go.

This will prevent leaks that lead to rusting. Screw the new panel in place as described. Drill a hole in the top corner on the valley of the corrugation not on the ridge. Ideally the wood beams will be located every 2 feet or 6 feet apart for steel beams.

Install the panel so that the short lip overlaps the large lip. Use the corrugated molding strips on the horizontal cross braces and the rounded ones on the vertical rafters. Place it at one bottom corner allowing an overhang of two inches on each edge. 2 corrugated metal roof installation instructions.
