c1224 roof Posted by jeff on 7/27/2005, 8:01 pm My father & I are discussing the pitch of the roof the roof for the c1224. He thinks it is a 10/12 with center at 16'. I think the peak must be off centre because of the upper set back from the front. Can you please let us know who is right to settle this argu..discussion. Also is pre engineered trusses better or rafters for this roof? Jeff  Post a Response

Re: c1224 roof Posted by John on 7/28/2005, 6:34 pm, in reply to "c1224 roof " Hi Jeff: I will settle the argument. You are right. The roof slope is 8in12, and the ridge is offset. It is basically centered over the second floor bedrooms, and the greatroom. It is 13' from the front wall (if the view is to the back) and 19' from the back edge of the veranda. We show this roof built with prefabricated roof trusses. I prefer this as it can be put together at the site quicker with less cutting and site calculations. The trusses accommodate 12" of batt fiberglass insulation. People are not using a spray on rigid styrofoam insulation, which can be sprayed directly to the underside of the plywood roof sheathing. This also acts as a air barrier too. If I were to go this route I would likely use stick framing (rafters and ceiling joists). This system does not require attic ventilation, as the attic is a heated space. I hope this settles the discussion for you. Thanks, John  Post a Response
