Abstract
Roofs for houses are primarily constructed off site, are disassembled and transported to the house construction site, and then reassembled, lifted onto the house shell, and nailed or otherwise affixed in place. Each roof section comprises one or more roof panels, ceiling joists, and upright supports. The roof panels include subroofing, roofing, and first joists extending along the slope of the roof, with facia and all other necessary elements to complete a roof provided. The ceiling joists have openings at both ends, and the upright supports have openings at one end with the other end beveled to engage a first joist. Dowels, which have a tapered end for ease of insertion, pin the ceiling joists to the first joist of the roof panel, and the upright supports. Sheet material, such as plywood, splices the upright supports to the first joists. Two roof sections are connected together at their apex by a ventable ridge.
