How to decorate and design the roof of a rural villa?

The roofs of self-built houses in rural areas can be either sloped or flat. However, the waterproofing and thermal insulation methods must be based on the geographical location. If it is in the north, it is necessary to first consider the roof structure level. Level it with cement mortar, then lay the insulation layer, and finally add a waterproof layer. There are more options to choose from, such as waterproof membranes and waterproof coatings. Finally, a protective layer should be added, and tiles or other decorations should be laid as needed; if it is in the south, because the average temperature is relatively high, the waterproof layer should be under the insulation layer, and the subsequent deconstruction process is the same.
