This document provides details on a roof truss design, including: The roof triangle has equal sides that extend from wall to wall at the base, with the two sides meeting at the center peak. The slope of the roof is stated as a ratio of rise to run, in this case 7/12, with a span of 6 feet and total run of 3 feet. The top chords are placed above the roof triangle and bottom chord below, with the span divided into thirds and quarters to locate the ends of the compression and tension webs. Triangular bearing blocks transfer the roof load between the top and bottom chords and ultimately to the walls. Gussets are applied to joints
