8Thus I have described the precautions to be taken at the beginning of a building, to prevent defects. The same importance does not attach to the roof, with its beams and rafters, because if these at any time are found defective, they may be easily changed. I have also explained how those parts which are not built solid are to be strengthened.
8I have now shown how buildings can be constructed without defects, and the way to take precautions against the occurrence of them. As for replacing tiles, roof timbers, and rafters, we need not be so particular about them as about the parts just mentioned, because they can easily be replaced, however defective they may become. Hence, I have shown by what methods the parts which are not considered solid can be rendered durable, and how they are constructed.
