- Release on:2020-11-10
PVC roofing is a great way to top a garden shed, shop, or patio. It is an easy, low-cost work, and you can do it yourself. You only need some basic tools and materials. We will see two methods for installing the PVC roofing panels. The first method is to cut the panels to the desired length. Most panels come up to 16 feet, which means 4.9 m in length.
In fact, the length of sheets can be customized. you just need to measure the length and ask the factory cut sheets to right length, which is convenient. Allow for a minimum of 18 inches which means 46 cm if you need to lap to complete the run. Tin snips are slow but safe. Wear work gloves and find the longest pair you can. The next step you need to drill holes in them. Use a 3⁄16 inches which is 4.8 mm drill bit. Spacing for the holes on the ends and sides of the panels should be 6 to 8 inches which is 15 to 20 cm.
The next step is installing the panels. Place them directly onto purlins that are attached to the roof trusses, beginning on the outside edge. Close or cover the back end. These will stop the entry of rain, wind, and pests. Screw down the panels. Drilling the holes, and use 10 by 2 in which is 25.4 by 5.1 cm screws with polycarbonate washers. Continue across the roof until it is completely covered, lapping over the previous panel by at least 2.5 inches which is 6.4 cm minimum. Next, complete the opposite side. If your roof is 2-sided and not just a single slope, repeat the installation on the other side of the roof, and install a corrugated ridge cap as you proceed across with the panels.
