Installing Plastic Roofing Panels
When you are seeking an appropriate covering for a property, you will find that corrugated plastic roofing is a popular choice. The panels will enable you to achieve a strong and stylish roof that is durable and hard wearing. To ensure that the panels offer the greatest benefit, it is essential that the correct installation process is followed.
Step 1 – Plan
Gather the tools and materials needed, which will mean noting the dimensions of the roof you will be working on. Either use a tape measure or check the dimensions obtained with the house details. This will be necessary to determine the number of panels that will be required to complete the project. Make sure you have the correct quantity before beginning.
Step 2 – Measure and Cut
If the corrugated plastic roofing panels cannot be bought at the correct size, you will need to cut them to the necessary dimensions. Carefully measure the panels and mark off the area with a marker. The excess can then be cut using a fine-toothed saw after securing it in a table vice.
Step 3 – Drill
It will be necessary to drill holes in the corrugated plastic roofing panels to accommodate the fasteners that will hold them in place. This will require a little arrangement to ensure that you drill a hole in the fourth corrugation of every panel. The hole should be around 10 mm from the edge, but this should be checked by dry-fitting a panel to test it. Similarly, check the drill bit in comparison to the roofing nail, which should be slightly larger in diameter to allow for expansion of the fastener in changing weather conditions.
Step 4 – Install Panels
If using a base, such as roofing paper, install this in the first instance. Starting at the bottom left of the roof, gradually work your way across the surface when installing the corrugated plastic roofing panels to fit them in lines. Make sure that the fasteners you use are specifically made for roofing purposes, which will help to prevent leakage. Use one corrugation to overlap when installing the panels, making sure that this is continued throughout the installation. After installing all the panels, clear away any debris and waste.
Step 5 – Seal and Finish
After installation, the roof will need to be sealed to avoid the ingress of air and water to make it fully integrated. Flashing will need to be fitted around the edge of the roof to help seal it and direct rainwater into the guttering. Securely nail it in place and use silicone sealant to the edges to add to the waterproofing ability. In addition, the sealant will need to be applied to the exposed edges of the plastic panels used to complete the roof structure.
