Necessary Fixings and Flashings for Your System

1. Decided What Necessary Overlap and Overhang

The sheets can easily overlap with one another because of it is designed in a “wave like” pattern, why it named corrugated sheeting. The length of this overlap will depend on the pitch of your roof, which should be detailed in your manufacturer’s guide. An overlap of 150mm is often recommended for roofs with 10° pitches, whilst 300mm is recommended for 5° pitches. Always allow for an overhang of at least 60-70mm so that water can run off without coming into contact with rafters or purlins, which can lead to damp and structural weakness.

2. Cut the sheets to size

Measure the length of your rafters and the distance between them. This should give you an area size for the sheets to be cut to. Depending on the material of your sheet you may need to use either a circular saw or hand saw. Either way, the sheet should be secured to a workbench so that you can get an even cut.

3. Choose the Overlap Direction

We overlapping the sheets in the direction of the wind. For example, if the wind is blowing from the east often if your area, the sheets on the left should overlap those on the right. This will prevent wind from blowing your sheets apart during the installation. This also very important in the following days.

4. Fix the First Sheet

Align your first sheet at the edge of your roof, ensuring that the necessary overhang is maintained. Then, fix your screws or nails through the corrugation and into the purlin. These should be run vertically and not overtightened. And then fix the remaining sheets. The rest of the sheets can then be fixed. Remember to overlap each sheet with the one before it and secure using vertical fixings.

6. Add Flashing

Some flashing pieces will be similarly be corrugated and as such can also be overlapped with your sheeting. Flashing should be installed at the ridge, eaves and at any point where your roof abuts a wall.

Extra Tips When Installing Corrugated Roofing

If you are thinking about installing corrugated roofing on your home or business, there are a few things you should know before getting started. Here are some tips to help you install corrugated roofing:

Make sure you have the right tools for the job. You will need a hammer, screwdriver, drill, saw, and screws. Measure the area where you will be installing the roofing. This will help you determine how much material you will need. Cut the panels to size using a saw. Make sure to wear protective eyewear when doing this. Drill holes in the panels using a drill bit that is slightly smaller than the screws you will be using. This will prevent the screws from splitting the panels. Install the panels by screwing them into place with the screws. Start at one end and work your way down the length of the panel.

When purchasing your sheets, try to order flashing and fixings of the same brand. This will guarantee that every part of your roof system will be compatible. When storing non UV protected sheets outside ensure they are protected from any direct sunlight that may cause cracks or distortions. Try to avoid fitting on particularly windy days as sheets can be blown away and damaged. Avoid cutting PVC in cold weather as this may cause serve damage. These sheets should be stored in a warm room for 2-4 hours before cutting.
