Analysis of the Causes of Deformation Arching of Resin Tile Roof

There are two main reasons for the deformation of the resin tile roof:

1. It is a quality problem, and 2. It is an installation proble

One: the quality of the resin tile is poor
For example, the resin tile processed from the recycled material is easy to be arched. In addition, when the resin tile is produced, the technology is not closed, resulting in a large moisture content of the synthetic resin tile, resulting in shrinkage deformation. Such a resin tile is formed after being installed on the roof. Uniform crowning.
Two: resin tile installation is not standardized
1. The spacing of the purlins installed on the resin tile is 660mm. If the spacing is too large, the resin tile roof will be arched or sunken;
2. The elastic line should be leveled on the surrounding wall according to the design elevation. The horizontal line is prevailing when the nail is installed. The height of the arching of the horizontal line is 1/200 of the short span of the room, and the longitudinal arching should be suspended;
3. The keel should be straight and should not be twisted and have a thrifty cross-section;
4. The synthetic resin tile is not tightly coupled to the force node, and displacement deformation will occur after the force is applied.
If the thickness of the tile is too thin (3.0mm is the national standard thickness), especially covering the color steel tile, the heat expansion and contraction ratio of the two materials is different, and the thin synthetic resin tile is more likely to be bubbling. Therefore, when we purchase synthetic resin tiles, we must select a regular large-scale resin tile manufacturer or brand. The quality of resin tiles is guaranteed, and we should not be tempted by low prices to suffer greater economic losses. When installing, it must also be strictly in accordance with the installation regulations, so as to avoid unnecessary troubles caused by improper installation.






PVC roofing is one kind of single ply roofing, which means it consists of one layer manufactured in a factory. A PVC roofing membrane is made of thick, flexible UV-resistant thermoplastic material; it may also contain polyester or fiberglass, resins, pigments, plasticizers and other chemicals. The thickness of the roofing membrane varies by manufacturer.

Versatility of PVC Roofing

Although white is a common color since it reflects the sun’s heat, different colors are available. Lighter colors like tan, grey or cream are preferred, and some newer types of PVC roofing contain reflective elements and are also Energy Star or Cool Roof rated. Some brands of PVC roofing can be customized with colors or logos. Some brands have a design which looks like conventional shingles from a distance.

PVC roofing can be made to fit nearly any flat roof shape, and is considered a fire safe material. This type of prefabricated flat roofing material is also inexpensive and has good general weather resistance. However, it is normally not used in areas with heavy rains or snow. PVC roofing is also may become brittle in very cold weather. Most PVC roofing membranes are designed to last about 15 to 20 years, although some premium products may have longer warranties.

Installation Process

Some PVC membranes come in panels, while others are adhered to the roof deck, and other others held down by stone or concrete. Some brands of PVC roofing are fleeced cushioned, which allows the membrane to be installed on rough substrates. Many types of PVC membranes are hot welded or fused together to make waterproof seams. Specialized welding equipment is used to join the roofing components together.

Installing and maintaining flat roofing is very different than installing standard asphalt shingles. The longevity of PVC roofing often depends on the skill of the installer and the quality of the seams. Homeowners should choose an experienced roofer who has worked with PVC roofing extensively. All PVC roofing should also be inspected every 6 months so any potential problems can be quickly fixed.
