Hip roof w/vaulted ceiling

[sammm]

Is it possible to have a building with 8' walls and still have at least a 10' ceiling in the center area?

Could trusses be manufactured to accomplish that? Most hip roofs I've seen have horizontal rafters running wall-to-wall (on the top plates) across the width of the building.

Sissor (sp?) trusses

yes, like trbomax said, scissor trusses. but you could also put a raised ceiling, or just put joist(windbeams) at 10' height

Sure is. Scissor trusses are probably the most popular way but it depends how much of the area of your building you want to have the 10' ceiling and how fast you want it to get down to 8' at the walls.

Or look at some of the old hiproof barns or wood quonsets.

Or, look into vaulted parallel chord trusses.

Thanks for the replies. The building is only going to be 16x24 (that's as big as I can fit on my property) and I'd like to be able to add a lift (MaxJax most likely) after it's built.

Any downside to having the joists at 10' vs. sitting on the top plate?

I'll check out scissor trusses too. Thanks again!

sam, the ceiling joist, besides giving you some place to attach your ceiling to, suport your 2 outside walls from bowing out from the weight of your rafters, roof. as long as its done right, theres no reason why you cant move the ceiling joist up to 10'.

To help clear up a misconception... a traditional barn is not a hip roof. It is a gambrell roof.

A hip roof has no gable end, it has eaves all the way around the building.


...just sayin'

Here's mine - it's a single bay, 16x25. It has a hip roof and the ceiling is vaulted. This is a composite of seveal pics, so you have to overlook the distortion, but hopefully you'll get an idea of the inside.

That's exactly what I want mine to look like, thanks! The size is almost the same as my plan too....I'm planning 16x24. What is the pitch of your roof?

I'm guessing your roof was all stick built? What about the sill plates? They look much beefier stacked 2x4's. Engineered beams?

Yup, it's stick built and is attached to the house. Sill plates are stacked 2x4's in that garage.

Bringing this one back for one more question. According to the triangle calculator I found, the finished ridge height (outside) of my building should be 14'. If it's 16' wide with a 1' overhang and an 8/12 (33.69 degree) pitch.

8' walls plus the 'a' length = 14

I supplied the 'A' angle of 33.69, and the 'b' length of 9 (1/2 width of building + 1' overhang)

Make sense?

yes it does, (inverse tan)(8/12) = 33.69 degrees

BTW, your roof rafter will need to be 10.81 ft

9 / cos(33.69) = 10.81
