With the continuous growth in demand for roofing projects in recent years—including renovations of privately built homes, refurbishments of industrial plants, and restorations of historic cultural and architectural sites—synthetic resin roofing tiles have become the mainstream choice in today’s roofing materials market, thanks to their comprehensive advantages of being lightweight yet strong, weather-resistant, corrosion-resistant, and easy to install. However, the industry is filled with a mixed bag of brands, and substandard products from many small manufacturers often develop issues such as fading, brittleness, and water leakage after just two or three years of use...

The barrier to entry in the resin roofing tile retail industry is low, but most stores go out of business within two years due to poor product selection and insufficient customer acquisition. The key to product selection is to focus on high-volume main colors, stock secondary colors in small quantities, and prioritize thicknesses of 1.5 mm and 2.5 mm, while avoiding overly complex designs. Customer acquisition should focus on a 3- to 5-kilometer radius around the store; specific strategies are not detailed in this article. The core lies in these two key points: product selection and customer acquisition.

The service life of PVC roofing tiles is significantly affected by climate and installation conditions. Humid and hot environments in the south, with high UV exposure, accelerate aging; in regions with large annual temperature fluctuations, the material’s resistance to aging decreases by 5%–8% each year; in coastal areas with high salt fog levels, the service life must be adjusted accordingly. Low temperatures in the north cause the material to become brittle, but dry conditions with little rainfall slow down oxidation. The installation environment is equally important, and its specific effects require further analysis.

Gao Yi PVC roofing tiles are manufactured using a one-piece extrusion process, resulting in a seamless surface that allows rainwater to flow smoothly down the slope. The material is non-absorbent and highly dense, providing excellent waterproofing performance. Water-diverting ribs are installed at the overlaps to guide rainwater away. The installation angle must be greater than 10 degrees; in actual use, no water leakage has occurred even during heavy rains. However, since the tiles themselves do not provide sufficient waterproofing, proper treatment of installation joints—such as the roof ridge and eaves—is equally critical, and special attention must be paid to preventing leaks.

The specifications for synthetic resin roofing tiles primarily include thickness, width, length, and effective overlap width. These specifications vary significantly among different manufacturers, and selecting the correct specifications is critical for the roof’s load-bearing capacity, waterproofing, and wind resistance. Common thicknesses range from 2.5 to 3.0 mm; 2.5 mm is suitable for flat roofs or light-gauge steel structures, while 3.0 mm is recommended for steeply sloped roofs or regions prone to frequent wind and snow. When purchasing, pay close attention to the thickness specified in the warranty and be wary of some...

Recently, demand for PVC-coated steel roofing tiles has been strong, with shipments accelerating as customers place direct orders for specific sizes. Following the end of the rainy season, demand for these tiles has surged in rural self-built homes, factory buildings, carports, and other applications, as they are lightweight, easy to install, cover a large area, and save on labor costs. In urban construction projects, color-coated steel roofing sheets are often the preferred choice. Customers prioritize their light weight, ease of installation, and service life.

With eight years of experience in the building materials wholesale industry, I’d like to share some tips on selecting a PVC roofing tile manufacturer. Avoid making decisions based solely on price quotes; instead, inspect the production line to confirm that the raw materials are brand-new, and examine the tiles’ details—such as their cross-section, color uniformity, and scratch resistance. Additionally, large manufacturers with a good reputation can typically ship orders the same day, helping you meet your project deadlines.

When selecting a manufacturer of PVC-coated steel roofing tiles, consider annual production capacity, warranty duration, and the level of cooperation during installation. Domestic production capacity is concentrated in Hebei and Guangdong. Do not focus solely on unit price; long-term durability is more important. When evaluating production capacity, pay attention to average monthly shipment volume, current orders, and the number of production lines, and conduct on-site inspections of vulcanization machines and production lines. Reputable manufacturers offer a warranty period of at least ten years and products with a long weather resistance lifespan.

The quality of resin roofing tiles depends on the manufacturing process, particularly the raw material ratios and calendering temperature. Neglecting formulation and molding details—such as shortening the mixing time or failing to maintain proper temperature control—can lead to premature peeling, fading, or yellowing of the tiles. Precise control of the proportions of raw materials—such as ASA resin and PVC pellets—as well as the calendering temperature (130–150°C) is crucial for ensuring product quality and service life.

Gaoyi Resin Tile’s export business continues to grow in Southeast Asia, the Middle East, and Africa, with overseas buyers prioritizing compliance with standards, consistent delivery, and cost. The product features superior UV weather-resistant coating technology, excellent color consistency, a low cracking rate, and a high repeat purchase rate. Prices are 15%–20% lower than those of local manufacturers in Southeast Asia, and the cost remains competitive on a CIF basis after ocean freight, making the product suitable for price-sensitive projects. Delivery times for export orders are approximately 4...
