dtontarski Posted October 15, 2014 Report Share Posted October 15, 2014 I have never observed a roof framed with other than rafters or engineered roof trusses - that is until yesterday. Yesterday I inspected a 1986 rural built home with roof framing that ran parallel to the home's load-bearing walls. Has anyone every observed a roof framed in this manner?

Erby Posted October 15, 2014 Report Share Posted October 15, 2014 Yes, as long as the rafter ties are there, it's not a problem. Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted October 15, 2014 Report Share Posted October 15, 2014 Yes, as long as the rafter ties are there, it's not a problem. In this case they wouldn't be rafter ties, they'd be ceiling joists. There is no outward thrust- each framing member is a beam and all the load is vertical.

Marc Posted October 15, 2014 Report Share Posted October 15, 2014 If the walls are not load bearing then beams are needed to transfer the weight of the roof/ceiling assembly to load bearing columns. It's akin to an ordinary house with a garage; a beam across the front of the garage opening transfers the weight of the ceiling and roof to the sides.

mjr6550 Posted October 16, 2014 Report Share Posted October 16, 2014 I see this done in some old row houses with low-sloped gabled roofs. Just think of it like a flat roof-ceiling joists spanning from bearing wall to bearing wall. There is an issue with this type of framing when used on a roof that does not have a relatively low slope. The roof load is partially transferred to the narrow dimension of the joist and therefore the joists cannot span as long as if they were oriented vertically.

Jim Baird Posted October 20, 2014 Report Share Posted October 20, 2014 ...looks pretty short up there, and I think I see a break of slope into more than one direction? Low slope all the way, ergo the fatness of frame members? mjr states description well. Quote Link to comment Share on other sites More sharing options...

Rob Amaral Posted March 24, 2015 Report Share Posted March 24, 2015 Not seen a modern light frame building, but that's a 'common purlin' method of running framing... Quote Link to comment Share on other sites More sharing options...
