What are Corrugated Roofing Sheets?

 What are Corrugated Roofing Sheets?

Corrugated roofings are metal sheets that are rolled and formed into metal panels. These are installed to the roof with screws and come in a round and wavy shape. Their excellent durability makes them ideal for commercial, residential, and agricultural applications requiring tough metal roofings.


Safety Reminders

Before installing your corrugated roofing sheets, safety should always be your priority first. Don’t forget to wear the following protective equipment:

  • Rigging gloves
  • Steel capped boots

Also, use a ladder to help you load the roofs you need to install. Don’t forget to remind your children to stay away from the location of your installation to prevent any harm, especially when you’re working on a DIY project.


Fixings and Flashings You’ll Need

  • Screw and nails – these fixings must be installed at the top of the corrugation sheets at 200-300mm centers.
  • Eaves filler – these are made to fill the space between your eaves and sheets which is made by the corrugations.
  • Wall flashing – this is needed when your roof sheets are about a wall to avoid the entry of water.
  • Ridge cap – this is used to protect the ridge of your roof.
  • Verge – this helps to finish the sheets where your roof meets the gable.


Materials You’ll Need For Installation

  • Tape measure
  • Hand saw or circular saw
  • Drill
  • Straight edge
  • Fixings and flashings

Let’s now discuss how to install corrugated roofing sheets. Make sure to prepare all the necessary materials you need.


Determine the Accurate Overlap and Overhang

Did you know the reason why corrugated sheets are designed in a wave-like pattern is to make the adjacent sheets overlap easily with one another? That’s how innovative corrugated sheets are. The length of the overlap varies on the pitch of your roof. Don’t forget to allow for an overhang of at least 60-70mm to let the water run off without coming into contact with purlins or rafters to avoid dampness.


Cut the Corrugated Roofing Sheets to Size

Cut the Corrugated Roofing Sheets to Size

Measure the length of your rafters and also the space between them to give you a better idea of the area size of your sheets to be cut to. You can either use a hand saw or a circular saw when cutting your sheets.  


Determine the Overlap Direction

If the wind is blowing from the east, then your sheets on the left should overlap those on the right and vice versa. This helps to avoid the wind from blowing your corrugated sheets apart.


Fix the First Sheet to Your Purlins

Fix the First Sheet to Your Purlins

Make sure to align the first sheet at the edge part of the roof. After that, fix the screws and nails through the sheets and into the purlin. Do not overtighten it, just run it vertically.


Fix the Remaining Sheets

Always remember to overlap each sheet with the one before it and secure it using vertical fixings.


Add Flashing

The flashing should be installed at the eaves, ridge, and at a point where your roof is next to a wall.

Other Tips for Installation

To ensure your safety before and during installation, these are the other tips you should remember.

  • Avoid fitting your sheets on windy days as sheets can easily be blown away and it’s also risky for your part.
  • Don’t cut the sheets during cold weather as this may cause damage. Make sure to store the sheets in a warm room for 2-4 hours before cutting.
