As science and technology continue to innovate and advance, our country's chemical industry is also making continuous progress. The rubber and plastics industry has made significant technological progress. The new type of waterproof material on the roof provides a material basis for the development of a single-story roof. Since then, single-layered roofs based on rubber and plastic have appeared in the field of low-slope roofing.

According to RSI Magazine's recent report, the new type of roofing waterproof material in the United States has been growing at an alarming rate. It has developed into a new type of roofing waterproof material that deserves our attention and is now being comprehensively introduced for the reference of our waterproof material industry peers. Monolithic roofing has achieved amazing growth in new types of waterproof material. It is well-known that the new roofing waterproof material technology has changed little in the 100 years before the 1960s.

All countries in the world use hot-tacked asphalt to lay 3 to 4 layers of bituminous membranes as a waterproof layer for new roofing waterproofing materials. This is called new laminated waterproof material (BUR). The United States is no exception. With the advancement of the chemical industry, the rubber and plastics industry has made significant technological progress, providing a material basis for the development of new waterproof materials for single-layer roofing and new waterproof materials. In 1962, the United States Carlyle Company laid a new type of EPDM roofing waterproof material membrane on the roof of the Chicago International Airport, creating a precedent for a new type of single-layer roofing waterproof material. Since then, new single-layer roofing waterproofing materials based on rubber and plastics have appeared in the field of new waterproof materials for low-slope roofs.

However, the initial development of new single-layer roofing waterproofing materials has been slow, and people are still habitually keen on more reliable laminated roofing new waterproofing materials. The world resource situation in the 1970s brought opportunities for the development of new waterproof materials for single-story roofing. First of all, the 1973 Arab oil embargo resulted in soaring oil prices and a shortage of new waterproofing materials for roofing of high quality roofing. At the same time, higher energy prices have increased the demand for new thermal resistance roofing new waterproof material systems.

This makes the new waterproof material for single-layer roof more attractive because it can be directly laid on advanced insulation boards such as polyisocyanurate and expanded polystyrene. At that time, some functional problems occurred in the new type of waterproof material for laminated roofs, such as double-layer failure and foaming on polyurethane insulation boards.

In spite of this, the new roofing waterproof material contractor was still cautious about the use of monolayers, and the new waterproof material for flat roofs was not modified asphalt. In 1997, it accounted for less than 10% of the new waterproof material market for low slope roofs. Since then, the material quality of new-type waterproof materials for single-story roofs has been continuously improved, construction technologies have been improved and improved, and new-type waterproof materials for single-story roofs have been rapidly and continuously growing, increasing to 25% in 1984 and increasing to 48% in 1987. Over half of the year, accounting for 54% of the market, has become a new type of roofing waterproof materials.

According to statistics, in 2005, the U.S. single-story roofing new waterproof material association member company provided a new type of waterproof material roll of 288.7 million m2 of roofing, which was more than twice the supply in 1984, and the huge output was seen. Single layer of roofing new type of waterproof material advances in solving problems and improving quality. Like many new technologies, single-layer roofing new waterproof material has experienced growing pains. In the 1987 investigation, the new type of waterproof material contractor on the roof encountered the most problems in the single-layer roofing new waterproof material. When the market share of single-layer roofing new waterproof material exceeds 50%, some contractors have reported that the destruction and recall of single-layer products are the most, as high as 75%.
