Points to note when choosing roofing materials

  1. Know the weight of the corresponding roofing materials, do you need to strengthen the house structure?
  2. Is the cost of the roofing material within your budget and can you accept the service life?
  3. Does the installation and maintenance of the roofing material require additional problems and costs?
  4. Can the roofing material provide good performance under the weather conditions in your area?
  5. Does the roofing material conform to the color and style of the building?
  6. Does the selected roofing material comply with local fire protection codes?

Factors influencing the durability of roofing materials

  1. Slope: Slope is an important factor for the normal function of the roof system. When the use of single-layer roofs and low-slope roofs have become a popular practice, it provides designers with an opportunity to design economical roofing systems and save the overall building cost.
  2. Drainage: The roof drainage system and slope are two completely different concepts. Drainage refers to the ability of the roof system to take water away. In the construction of new buildings, drainage is a simple design element that must comply with the requirements of the code.
  3. Fixing: The three commonly used laying methods for waterproofing membranes are empty roofing, mechanical fixing, and full adhesion. Coiled roofing with a protective layer (PMA) is the fourth type of composite fixing method, that is, the roofing coil is fully glued or not fully glued, but the insulation material requires pressing.
  4. Material durability: The durability of the material refers to the ability of the roof system to resist the spread of fire, weathering, natural or man-made influences without causing significant changes in the function of the coil.
  5. Constructability: Constructability refers to construction factors, including constructing a roof system on a specific building, and considering the location, height, construction method, purpose, and living conditions of the building.
  6. Maintenance: All roof systems should be maintained during their life cycle. Proper maintenance can extend the life of the building and ultimately reduce the cost of the owner. The choice of roofing system should also consider the difficulty of its maintenance. For waterproof membranes with exposed, coated, sandy or fine-grained surfaces, it is easier to maintain, and routine inspections are sufficient.
  7. Sustainability: The characteristics of sustainable roofing include reducing heat island effect, enhancing light reflectivity, eliminating rainwater block, and also including the impact on the environment (such as the impact of roofing materials on the environment during production, installation, handling, and disposal).

Applications of roofing materials

  1. The workshop, hood for vehicle: color steel tile, asbestos tile, PVC tile, etc., with short service life and good price.
  2. Private houses: clay tiles, glazed tiles, Spanish tiles, chain tiles, cement tiles, etc., bulky and unsightly, with good prices.
  3. Temples, pavilions, and other ancient buildings: ancient architectural ceramic tiles, ancient architectural metal tiles, etc., characteristic products.
  4. Wooden house, light steel structure: asphalt shingles, colored stone metal shingles, etc., asphalt shingles have a short service life, and metal shingles are expensive.
  5. Small villas, clubs, hotels, high-end residential areas: asphalt shingles, colored stone metal shingles, solar shingles, resin shingles, etc., relatively speaking, they are more beautiful and expensive.
