Under the roof of your home

People say that the main roof is above your head. In principle, why do I have a house without a roof, it makes no sense in it, but you can’t do without walls without walls. Also, the components of the roof and walls are not unimportant. For the roof, you can choose any material, it can be natural tiles, there can be a metal tile or folding roof, or can a shale roof, etc. But whatever material you choose, you still need to think about security and elements that ensure this security.
