The roof is a part of a building that functions as a cover for all the rooms below it against the effects of heat, dust, rain, wind or for protection purposes. Materials that are generally used for roof frames are wood, both plain wood and carved, which is adjusted to the economic capabilities of each occupant.
The shape of the roof affects the beauty of a building and the selection of the roof type should be adjusted to the local climate, it looks like what the architect wants, the costs available, and the material that is easily available.
The roof frame construction used is the frame of the easel. A truss arrangement that serves to support the roof load including its own weight and at the same time provides shape. Basically construction consists of a series of rods that form a triangle. Taking into account the weight of the roof and materials, the construction will be different from each other. Each arrangement must be a solid unity of form that will be able to bear the burden that works on it without undergoing change.
