Prefabricated Template for New House Roof

Prefabricated panels can be used for the roof of a new house, but their applicability and potential issues need to be carefully considered. Prefabricated panels are pre-made concrete components. To make them, a hollow mold is first nailed together, steel bars are placed inside the mold, and then it is filled with cement. After it dries, the wooden boards are knocked off to form the panel. However, there are some concerns when using prefabricated panels on roofs.

Firstly, in terms of structural stability
Prefabricated panels are placed directly on brick walls and are not an integral part of the wall structure. This means they cannot provide the effective tensile and stabilizing effects on the walls like a monolithically poured roof can, and only serve the basic function of covering the roof. In the event of geological disasters such as earthquakes, due to the lack of integral connection between the prefabricated panels and the walls, they are prone to displacement, collapse, and other dangerous situations, posing a threat to the lives of the occupants inside the house.

Secondly, regarding waterproofing performance
Prefabricated panels are installed by piecing them together one by one, and the joints are usually connected with concrete or cement mortar. Over time, these connection areas may develop gaps due to material aging, shrinkage, etc., leading to rainwater leakage. Especially in regions with high rainfall, the leakage problem may be more severe, not only affecting the normal use of the house but also potentially causing damage to the interior decoration and structure of the house.

Thirdly, concerning resistance to foundation settlement
If the foundation of the house settles, cracks will form between the prefabricated panels due to uneven stress distribution. These cracks not only affect the appearance of the roof but also further reduce its waterproofing performance and structural stability, increasing maintenance costs and safety risks.

Fourthly, regarding price factors
Currently, the prices of roof prefabricated panels on the market vary depending on factors such as brand, specification, and region. For example, there are different prices like 52.00 yuan per square meter, 159.00 yuan per square meter, and 28.00 yuan per square meter. When choosing prefabricated panels, one should not only consider the price factor but also comprehensively consider their quality, performance, and compatibility with the house.
