To install corrugated roofing start by cutting your panels to length with an angle grinder.
Corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch.
Take care the first piece is aligned precisely perpendicular square to the edge.
Minimum pitch for corrugated metal roof.
Install the roofing screws vertically along each rib in the panel.
Be sure the larger edge is laid so that the small edge of the next panel will overlap it.
Install metal panels or shingles align the first metal roofing panel so that it overlaps the edging by 1 2 to 3 4 of an inch and is square to the roof line.
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.
Space the screws about 12 in 30 cm apart down the entire piece of metal.
Once the first sheet is in place you need to install the remainder of the lowest row of corrugated metal roofing.
Generally keep your weight evenly distributed over the soles of both feet to avoid concentrating your weight on either heels or toes.
Beginning at the outside edge of your roof place each panel directly onto the purlins that are attached to the roof trusses.
Use your neoprene washer head screws to secure the metal to the sheathing.

Place nails on the center of the ridge of the metal where it bends away from the roof rather than towards the roof.
Use about 19 to 21 nails per sheet.
Use specialty nails with washers to secure each corrugated metal sheet.
Place the metal sheet at one corner of the roof overhanging the edge of the roof by 2 inches.
Next pre drill holes on the end and side ridges of the panels spacing the holes 6 to 8 inches apart.
