Under national standard testing, PVC roofing tiles exhibit good impact resistance at room temperature and can withstand a 120-kilogram falling ball impact. High-quality PVC formulations show no cracks or perforations even at -30°C. However, low-cost products made from recycled materials available on the market may become brittle when frozen; it is necessary to review test reports to ensure the reliability of the data. Since hail impacts are concentrated, resistance to such impacts requires further verification.
