the HOUSE roof. Position the truss to match the overhang of the Gable Truss tails. Set the dry line on the house roof, in line with the peaks of the 2 trusses, and 1 ½" above the peak of the temporary truss. Place a 16d nail through the roof and attach the dry line. Lay the truss on the house roof to be set LAST.

String a line between the single truss and the truss pack. Release the second truss from the bracing and transfer to the opposite end of the roof. Align the truss with the marks on the wall plate and nail fix into position using either method one or two shown on page five of this guide. Nail fix a timber brace to secure the second truss in place.
