The main material used on the roof of the gate and Poh San Teng temple uses wood-based materials. In ancient times, during the reign of the Ming Dynasty (1368 - 1644), many buildings were built using wood-based materials because wood is generally very strong, easy to find and durable. The technique used in the process of making the roof of Poh San Teng Temple is not to use nails but replace it with a chisel technique. For example, another building that uses wood as the main material in its manufacture is the Yingxian Wooden Pagoda, the oldest still living in China, which was built in 1056 based on wood.

The engineering Chinese used a system of cantilever and braces to provide buildings with sweeping roofs that usually sloped upward at an angle. The cantilevered roof appears to float above the main structure and reinforces the focus on horizontal symmetry.

In this system, building pillars are lined with carved stone cladding. The main purpose is to prevent the bottom of the pole from damage due to moisture. The main feature of the Chinese log frame system is that it allows a structure to expand without limitation.

From the design of the roof curve can also see that the ancient roof has smart, elegant, streamlined features. Its style is the highlight of Taoist Culture. Therefore, Chinese ancient roof contains both rational "ritual", but also contains the emotional "music". It is under the strict system but keeps its flexibility. Although it is in the method of modular system, it is sill flexible. Therefore, China ancient roof design is generated by fusing multicultural and has obvious cultural characteristics of "Neutralization". The solemn and intelligent features of roof itself can be sensed in the viewer's visual attention to resonate emotional experience with each other.
