David Lanfear owns an eco-friendly home building service in the United States called Bale on Bale Construction．He says he laughed when some friends first told him about houses built of straw．But after doing his own research, he learned that building with straw bales makes a lot of sense．He has now helped to build more than ten straw bale houses and says the building material is becoming more widely accepted．To build the houses, he fills a wood frame with tightly packed bales of straw．Next he coats the walls inside and out with layers of clay plaster．He says the common ideas about straw houses continue, including stories about the threat of fire．As a matter of fact, straw bale houses have done well when tested for fire resistance．And his builders use the same building methods as traditional builders to keep out rain．He says we use what we call good shoes and a good hat, and that would be a solid foundation and a really good roof

What does the underlined sentence mean?

Thanks

It means that his builders do not differ from the usual method of building to keep out rain.
i.e. a solid foundation and a good roof. (As in the final sentence of your quote).
