ok without ceiling joists? - Page 5

> If snowload is not a factor, I would go with 2X6 16"
> OC rafters and ceiling joists. 10' studs with
> fireblocking to address the overhead concerns. A
> beam to support the ridge and joists. Put continuous
> studs under that wall that supports the beam on both
> ends. Run a doubled up 2X12 beam across the 24'
> section midway. Put some mild 1/4" plate steel in
> it. 16' 2X12 will work if on one side is centered,
> scabbed the remaining ends. And, on other side 2 12'
> sections. Bolt together every foot top and bottom.
> Run a 2X2 on the bottom both sides of the beam.
> Birdmouth the ceiling joists to tie into the beam.
> Toss some plywood on the ceiling joists for a work
> area to build the ridge, tack nail the plywood. Nail
> a 2X6 flat, on top of the beam, full length of the
> beam, and nail it well. That 2X6 edge should be 3/4"
> offset from center of the beam. Nail a 2X6 90
> degrees with end up to the 2X6 you just nailed to the
> beam (you'll see why in a minute, its standing up).
> Double up 2 2X6s, nail together well. Cut down to
> the center, 1.5" slice, the height of the bottom of
> the ridge board. The ridge board will be supported
> by these during intial construction of the ridge, not
> for the ends or where the 2 ridge board join.
> Temporarily brace these 2X6s accordingly to get
> proper plumb and so forth. Mount the ridge boards,
> butt tight, ends can run long for now. Tack-Nail the
> doubled up 2X6s to the ridge board. Beginning at each
> wall, and working to the center, add a 2X6 every 64"
> parallel and underneath the ridge board. The bottoms
> should be nailed to the 2X6 that's standing on end I
> previously mentioned. These actually support the
> ridge. Brace for plumb both ends of these added
> 2X6s. Remove the temporaries. When done, add a 2X6
> between each of these supports at approximately 45
> degrees. Starting at the wall, point on the beam to
> the corner of the ridge and support. Run until
> nearing the center of the ridge, do similar with
> other side. Effectively, a girder truss. Remove any
> temporary bracing. Cut off the wild ends of the
> ridge boards. Add your rafters. Pull up the plywood
> and shove it off. Frame any remaining wall
> structures incidental to the roof framing.
