houses here usually have a 20 year warrantee, the frames are usually either steel or american soft wood, believe it or not, the walls are mostly brick veneer or concrete render, some plastic and timber cladding, pretty much the same as american houses so far. it all goes to shit in the usa when it comes to your choice of roofing material, instead of using concrete tiles or steel to match the rest of the house you choose bitumen soaked paper, you have no guttering or downpipes either so there is zero steel barrier to protect the most vulnerable part of the roof, the outer edges.
