To install corrugated roofing start by cutting your panels to length with an angle grinder.
How to put up corragated roofing.
Using galvanized nails attach the moldings.
Beginning at the outside edge of your roof place each panel directly onto the purlins that are attached to the roof trusses.
Next pre drill holes on the end and side ridges of the panels spacing the holes 6 to 8 inches apart.
Use the corrugated molding strips on the horizontal cross braces and the rounded ones on the vertical rafters.
Continue adding panels until the roof is covered.
Buy the metal panels.
Drill the screws into the corrugated metal panels onto the beams every 12 inches.
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.
Drill a hole in the top corner on the valley of the corrugation not on the ridge.
The process can be time consuming but with a nail gun it s significantly quicker.
Place it at one bottom corner allowing an overhang of two inches on each edge.
Use the rounded molding strips on the vertical rafters and the corrugated ones on the horizontal cross braces.
This will prevent leaks that lead to rusting.
Be sure before you fasten the roofing itself however that you lay down closure strips underneath where the screws will go.
Finish the first side of the roof.
Ideally the wood beams will be located every 2 feet or 6 feet apart for steel beams.
Attach the moldings using galvanized nails to prevent rusting in case of any leaks.
Step 4 line up the second sheet overlapping the first by one ridge and install it in the same manner.
2 corrugated metal roof installation instructions.
Lay the roofing felt.
The screws should be fastened at least 1 inch deep into the beams.
Insert about 20 nails into the humps of the ridges spread equally throughout the panel.
Install the panel so that the short lip overlaps the large lip.
Complete the first row.
For a secure and attractive finish you should use molding strips on top of the rafters.
Lay and secure the first metal panel.
The silicone will spread and adhere creating a seal.
Continue this process until all the panels are safely affixed to the ceiling.
You may need to cut panels to fit angles using a circular saw with a metal saw blade.
