TECHNOLOGY TODAY PHOTOS & FACTS

Framing: Roof Basics Virtually all roofs on new homes today are built with pre-fabricated trusses which go up much faster than hand-framed roofs, and even on smaller additions it's often easier to order a few trusses and raise those than to frame the roofs by hand. So we'll assume that most people will lean toward trusses in their own projects and explain the following basic steps on how to build a simple gable roof with trusses. Ordering Trusses Marking Cap Plates Securing Gable End Truss Raising Trusses Positioning and Bracing Trusses Building Gable End Overhangs Sheathing Roofs Building Soffits But there's always a bit of hand-framing to be done on a new roof, even if the main structure is built with trusses--especially on additions where the new roof usually has to be tied in to the old roof or to an existing house wall. And you might be interested in a couple other roof projects. So in our next roof framing page, Special Roof Techniques, we'll give you a quick idea on how to tie a new roof into an existing one, how to hand-frame a small hip roof and how to build a gable dormer. CAUTION: Roof work is always dangerous, so please read over some Important Safety Information we've filed on site here before starting your next project

Raising Trusses Once the gable end truss is fully secured, plumbed and braced, you can raise the other trusses up onto the walls. But that can be awkward since trusses are usually long and unwieldy. On large projects, contractors will often hire a crane to lift the trusses up, but that's expensive. Doing it by hand is possible (and cheaper) but it requires adapting steps similar to those below to fit your situation. Set one end of a truss on one wall plate with the truss upside down. Set the other end on the other plate. Swing the truss into its upright position. Rest it against the gable end truss already secured. Raise the other trusses the same way, one by one, and stack them against the gable end truss, making sure the other gable end truss is the last one to go up. Two people can handle this routine if they have ladders and scaffolding standing by to safely climb up into position to swing the trusses up and stack them up one by one. But ideally, there would be a couple people up on the wall plates pulling the trusses up and a couple people below pushing--especially on 2-story buildings. (And possibly a fifth person with a pole or a 2x4 to help tilt up the peaks) MORE TRUSS TECHNOLOGY
