A system and method for securing the wall framing and roof of a building structure against wind. A cable tensioner, located between two uprights of the wall framing and below the top plate, is attached to an anchor secured in the foundation. A cable extends over the first roofing member, under the top plate, over a second roofing member, through the cable tensioner, and over a third roofing member. In another embodiment, a cable tensioner has a vertical sleeve, a hollow tube affixed to the vertical sleeve, a rod extending through the vertical sleeve, and a nut threaded onto the nut for tensioning the cable.
