I had to look up the terms for the various parts of roof framing online, so if I say something that doesn’t make sense, let me know.
My garage has a hip framed ceiling, and I want to finish the inside (insulate, add drywall). I’d like to keep the vaulted ceiling, rather than put in joists and have a low ceiling.
The hip rafters and the ridge rafter are larger than the other rafters (I think the normal rafters are 2x6 and the hips/ridge are 2x8s).
How would you hang drywall for such a ceiling? Do you cut a 2" rafter extension to attach to the regular rafters? Is there some kind of spacer that you attach the drywall to?
I’m not planning on doing this myself, just trying to wrap my head around what would be done.
You can do it that way. They will be an odd dimension so you have to rip a lot of lumber. Or sister an additional board alongside each common rafter and align them with the lower edges of the hips. You do increase the width of the common rafters and complicate the insulating. They may make a metal stud piece that will so this.
Or: just place the drywall only on the commons and butt the sheets into the hips and ridge. This will leave 2" of the hips exposed like beams and can be a neat look. This would be the fastest method.
Whatever you do you should leave ventilating space above the insulation so that must be planned in advance. You will need to add a ridge vent and soffit vents also.
My living room ceiling is hip framed and I covered it with 6" V groove barn siding that butts on the face of the hips. A whole lot of compound bevel-mitres involved!
Another way to deal with the exposed ridge would be to add collar ties fairly high up. Then you have a narrow flat ceiling. My living room is done that way (also with v-groove siding!) and it is a nice look.
Lots of interesting photos. My ceiling is done with wood like those, except they cut their boards to meet at a 90 degree angle, I cut mine to continue straight across the hip:
Now my porch ceiling I cut to meet at a 90 degree angle.
