Truss Options - Fine Homebuilding Valley Trusses When a house has one section running perpendicular to another, the intersecting roofs form valleys To build these valleys with trusses, you run the first roof frame straight through the main section of the house After sheathing the main house, use step-down valley trusses to build the intersection are on top of the roof deck
Building Hip and Valley Roofs With Trusses - Fine Homebuilding Our methods for assembling hip-and-valley truss systems have evolved a great deal since that first puzzled attempt The biggest advance in our technique came when we described the process to our crane operator He suggested assembling some of the trusses on the ground and lifting whole hip sections onto the house in one shot It worked like a
Installing Valley Trusses???? - Fine Homebuilding For two intersecting roofs Usually, I would stick frame but the truss company sent valley trusses I thought since they were here already it would be faster But I have no experience with these so any suggestions for the install are appreciated Thanks Edited 6 25 2005 9:24 pm ET by BHACKFORD
Framing Tricky Truss Roofs - Fine Homebuilding We start with a girder truss because once the girder truss is fastened to the other trusses that it helps to support, these assemblies are sturdy and largely self-bracing We also find it easier to compensate for irregularities in the layout by adjusting common trusses rather than girder trusses and the hip and valley trusses that attach to them
Roof valley with trusses - Fine Homebuilding I thought it might be informative to show how my truss supplier details members when dealing with a valley and large overhangs This pic shows how the large 40 5″ overhang and 13 5″ heelstand is done with the common trusses, and how “clipped tail” trusses are required at the valley
Trussed valley Q - Fine Homebuilding In the left valley, I clipped the truss lines to the valley, and here is where I modeled my "valley block" which ties the ends of the clipped truss tails together In the drawing, the garage roof ridge is vertical, and the its roof joins the house roof at a right angle
Truss valley overframing - Fine Homebuilding (ie: They build a 4' valley, then 8', 12',16', etc ) My suggestion for laying them out is to run a string line where the ridge should be Then slide the trusses up the slope until they touch the string and nail them wherever they land Valley trusses always seem to fit so poorly that there's no point trying to calc exactly where they should go
Conquering Complicated Roofs - Fine Homebuilding Measure the distance from the valley birdsmouth to the hip birdsmouth; the valley’s run will always be longer than the hip’s run by this amount 7) FIND THE PLAN ANGLES I typically draw in the ridges, but they’re really only useful to include when you have a broken hip or want extra accuracy when calculating valley-jack lengths
Framing a Roof Valley - Fine Homebuilding The valley rafter has a different pitch The run of the valley rafter is longer than the run of the common rafters, so it takes 17 in of run for the valley rafter to rise the same distance that the common rafters rise in 12 in Therefore, the pitch of the valley rafter is 12-in-17
Hip-Roof Framing Made Easier - Fine Homebuilding Framing a hip roof is a head-scratcher for most carpenters, but it doesn’t have to be The process became a whole lot easier for me when I realized that the primary challenge in building a hip roof is one of layout, not math
