Having handled a large volume of PVC roofing tiles over the past 15 years, I have found that there is a significant gap between the reputation of well-known manufacturers and the actual quality of their products. Truly reliable manufacturers must have advanced equipment and strict quality control—not just rely on advertising. Products from small workshops often suffer from issues such as color inconsistencies and poor impact resistance. I recommend requesting third-party test reports and factory inspection records from the manufacturer to verify quality.
