When purchasing PVC roofing tiles, the biggest concern is the wide variation in quality. Since they all look pretty much the same on the surface, they are prone to warping and fading after two or three years of use. In fact, it’s not difficult to determine the quality of PVC roofing tiles. As long as you keep a few key points in mind during the purchasing process, you’ll naturally have a clear idea of what to expect.
PVC Roof Tile QualityHow to determine
The most straightforward way is to examine the cross-section. Stand the tile upright and hold it up to the light. If it is high-quality PVC roofing tile, its cross-section will be very dense and uniform. You should not see any obvious air bubbles or discoloration in the cross-section. The color should have a matte finish.
You can hold it in your hand to get a feel for its weight. For items of the same size and specifications, the heavier it is, the higher-quality the materials used. If this tileIt has a very springy feel, That indicates the additive has been added in the correct amount. It also shows that its flexibility meets the required standards.
Please double-check the information on the manufacturing license. Roof tiles produced by properly licensed manufacturers typically have the relevant standards, production batch number, and specific production date directly stamped on the back; these markings should be clear and legible.
If a product merely bears a certification label whose clarity and accuracy cannot be guaranteed, or if the product itself lacks any form of identification whatsoever, it is highly likely that the quality of the raw materials used and the overall production and processing procedures have been unnecessarily simplified or cut corners at multiple stages.
What Are the Characteristics of Poor-Quality PVC Roof Tiles?
The one thing that people can feel most directlyThe smell is pungent. Break off a small piece of the material and give it a sniff; a qualified product will have only a very faint plastic odor; If the smell is very pungent, has a sour odor, or has an unusually strong sweet smell, then you can generally conclude that recycled materials or low-quality plasticizers were used, causing the product to become very brittle in cold weather.
Another way to inspect the product is by examining its surface. Poor-quality PVC roofing tiles have an abnormally high gloss, appearing as if they’ve been coated with a thick layer of wax; this is typically caused by an excessive amount of powder in the filler. Scratch the surface firmly with your fingernail; if powder comes off or deep scratches remain, this indicates that the outermost layer of material is too thin.
Under these circumstances, after four to five years of continuous use, the wallpaper is prone to chalking and peeling. The hassle involved in having to tear it down and re-wallpaper often far outweighs the initial savings of a few dozen yuan.
When selecting PVC roofing tiles, be sure to focus on the material cross-section, manufacturing markings, and surface odor. Don’t just compare prices, and don’t be fooled by the packaging. As long as you choose the right material and stick with qualified manufacturers, these tiles will last for over a decade on your roof.
