How to Cover the Roof of a Container House

Covering the roof of a container house requires selecting appropriate methods based on the type of house, with common steps including roof panel installation, waterproofing treatment, and detail refinement.

1. Roof Panel Installation

Roof panel installation for container houses is typically carried out after wall panel installation. Taking the installation process of Zhongnan Steel Structure container mobile houses as an example, during wall panel installation, positions need to be reserved on the roof. Then, the roof panels are placed over the top frame of the house to ensure a tight connection between the roof panels and the house frame. There are various options for roof panel materials. The common one is container corrugated panels, which generally have a thickness ranging from 1.2 to 3.0 mm. These panels are roll-formed from weather-resistant steel plates or galvanized steel plates. This material has high strength and can meet the basic load-bearing and protective requirements of the house. Some container houses may also use other prefabricated roof panel materials, similar to the combination with light steel structure walls. However, during installation, special attention should be paid to the firm connection with the overall house to prevent issues such as looseness and water leakage.

2. Waterproofing Treatment

Waterproofing is a crucial step in covering the roof of a container house. After roof panel installation is completed, comprehensive waterproofing treatment should be carried out on the roof. You can refer to the requirements of some waterproofing projects, such as applying waterproof coatings on the roof to form a continuous waterproof membrane and prevent rainwater penetration. For parts of the roof that are prone to water leakage, such as joints and edges, structural sealants should be used for sealing treatment to ensure good waterproof and sealing performance of the container. Structural sealants can effectively fill the gaps between the container bodies and prevent rainwater from entering the house through the gaps.

3. Detail Refinement

After the overall installation of the house is completed, detail refinement of the roof is also necessary. Check the flatness of the roof to ensure that the ridge lines form straight lines at places such as gable walls and wall bases, that the water-adding parts are straight, that the connecting pieces are straight both horizontally and vertically, that the seams between the long-direction overlapping sheets of the colored plate structures form straight lines and are perpendicular or parallel to the relevant axes. At the same time, ensure that the surface of the colored plates is evenly glossy, free of contamination and damage, that the connecting pieces are firmly fastened without loosening, that there are no indentations on the plate surface, and that the surface of the colored plates has no wrinkles or misaligned holes.
