What Are the Different Types of Roof Ventilation?

Roofing engineering is one of the main parts of building construction engineering. It includes both materials and equipment used in engineering and technical activities such as design, construction, and maintenance; it also refers to the object of engineering construction and plays a functional role. In particular, in addition to safely carrying various loads, roofing projects also need to have the ability to withstand temperature, wind, rain, ice, snow, and even earthquake damage, as well as deformation caused by temperature differences and expansion and cracking of the base structure. Therefore, the roofing project plays a very important role in a house building that is safe, environmentally friendly, and meets people's requirements for use and aesthetics ^[1] .

Roofing engineering is a sub-project of housing construction. It is a large engineering field. Its main body covers the upper roof slab and all structural levels above it, including:

1. Comprehensive:

With the advancement of science and technology in housing construction engineering, roofing engineering has developed into a comprehensive system with many categories, extensive contents, and complicated technology. The development of roofing system projects needs the attention of construction administrative departments, construction units, and designers. The overall concept of roofing projects should be established, with the goal of improving the overall technical level of roofing projects, unified planning, and promoting the combination of materials, design, and construction and coordinated development capabilities achieve. In roofing system engineering, paying attention to the development of complete sets of waterproof technology is the main goal and task of the building waterproofing industry ^[1]

The development direction of roofing engineering is to promote the development of system technology. Practice has proved that the development of roofing engineering system technology has played an important role in meeting the functional and economical, applicable, and aesthetic requirements of various types of buildings, and is a basic experience of many developed countries. Over the years, based on the introduction of advanced technology, equipment and independent innovation, China has researched, developed and summarized a number of roofing engineering systems with good economic and social effects, promising development prospects and worthy of promotion. The 8 types of roofing systems listed below are the trends and goals of the development of roofing projects in China ^[1]

1. Vigorously promote high-quality modified asphalt waterproof membrane and polymer waterproof membrane;

2. Actively adopt environmentally friendly waterproof coatings and highly elastic sealing materials;

3. Efforts to develop new waterproof technologies and new materials that conform to the "four-section environmental protection" industrial policy;

4. Restrict development and restrictions, and prohibit the use of backward products and technologies;

5. Strictly abide by and strictly implement waterproof material product standards and waterproof engineering technical specifications;

6. Strive to achieve the serialization and matching of waterproof material products, and standardize the professionalization and systematization of waterproof engineering application technology ^[1] .
