If you are planning to repair an existing roof or building a new one. You can look at the selection of roofing materials for the garage, depending on your needs and budget. If you are building your garage from scratch, you can probably view this link https://heydenframeandtruss.com.au/timber-roof-trusses/ to start making the roof by this point.
Some people like to build the roof trusses as part of the wall structure – with each frame standing on two vertical pillars and each set of frames and pillars forming a cross-section of the entire structure. In some cases, it might be a little awkward to work with.
To do this in a slightly more manageable way, you can first erect the wall structure, stabilize it, and then install the frame. When you are ready to work at the head level it is a good idea to place the scaffolding on top. Not only is it safer to work from a ladder, but also easier because both hands are free to work.
This is a job for two to three people. The first thing you need to do is mark the location of each frame at the top of the wall where the frame will eventually be attached. The distance between the fields is determined by the needs of the roofing material of your choice.
Heavy materials require a lot of support, which means less space between frames. Then the first frame is lifted against the wall so that it crosses the garage floor. The frame is then lifted by attaching a long block with small ropes to the very top of the frame then pushing it into an upright position.
