This installation guide for Gaoyi PVC roofing tiles is based on my actual experience working on construction sites. Because PVC roofing tiles are relatively lightweight and can be joined quickly, they eliminate the cutting step required for resin roofing tiles and weigh more than half as much as color-coated steel roofing tiles, making them a hassle-free choice for factories, carports, and warehouses. Next, I’ll explain the process in detail, covering three key aspects: the furring strips, tile installation, and finishing the edges.
How to Control the Spacing and Fastening of Joists
C-channel steel or square tubing is typically used for the purlins, and the spacing between them should be kept within the range of 60 to 80 centimeters. If the span is large, a smaller spacing value should be selected. Last year, I worked on a carport project in Suzhou. When the spacing was set at 80 centimeters, a typhoon struck. The roof surface as a whole did not deform, but the joints were pulled slightly taut. If the spacing had been any wider, the structure would have appeared unstable, which could have caused the roof tiles to curl up.
You must use self-tapping screws and include rubber washers, Make sure there is one nail per holeUnder no circumstances should you use ordinary nails and force them in by hammering. This is because, after PVC roofing tiles are subjected to external forces, if they are secured with ordinary nails, they will become loose within just two weeks. Once rainwater pours in, the entire project will be for nothing, and carrying out rework and repairs later on is far more troublesome than simply starting over from scratch.
Overlap Width and Edge Finishing: Easily Overlooked Details
The width of the overlaps must be maintained between 20 and 25 centimeters, and they should be arranged in a downward direction following the flow of water. On one occasion, to save time, the panels were overlapped by only 15 centimeters. As a result, during a heavy rainstorm, rainwater seeped directly through the gaps and stained the entire ceiling below.
When finishing the edges, you should use special grooved clamps for securing them. Never use silicone sealant, as it will delaminate and fall off after a week of exposure to intense summer heat, and is even more prone to cracking in the cold winter months.
The edge-closing channel must be pressed into the roof surface to a depth of 5 millimeters., Only by doing this will it not be blown away when the wind picks up.
If you want to know how to install those Gao Yi PVC roof tiles, the secret to this entire tutorial is actually very simple—it’s just three steps. These three steps are: first, set up the framework properly; second, stack the tiles tightly; and third, make sure the seams are completely sealed.
As long as you follow all three steps mentioned above, you’ll essentially avoid any leakage issues. Under normal use, it should last for eight to ten years without any problems.
