How to install galvanized steel corrugated roof panel.

To install corrugated roofing start by cutting your panels to length with an angle grinder. Place the first screw about 7 inches from the bottom and each subsequent screw about 18 to 24 inches apart along the vertical run. On hip roofs this crew prefers to begin at the center and work outward. When it comes to installing the metal screws be careful not to drive screws too deep.

Install the roofing screws vertically along each rib in the panel. By installing the first panel square the rest will follow suit. The washer under the screw head should seal to the surface of the panel without bulging or shifting. This will keep the wall straight as you place additional panels.

Install the first galvanized roof panel at one bottom corner. Secure the screws but do not overtighten. Beginning at the outside edge of your roof place each panel directly onto the purlins that are attached to the roof trusses. Fasten it with galvanized screws with plastic washer caps by using a screw gun.

Side laps should still face away from the wind. Start at the end of one wall and use square up.
