Hip Roof Without Ceiling Joists

It seems to me that.

Hip roof without ceiling joists.

I ve worked on homes 120 years old with 1x6 hips and no sign of bracing or king posts and no sign of failure either. The shape and size of a roof depends on the span and the floor. As a follow up to my previous post on a 18x25 hip roof can i place an lvl beam 18 span so that the ceiling is now essentially split into 2 sections each one 18 wide and 12 5 long. With no posts under the hip or ridge would it want to kick out and the ridge go down.

The angles are basic and even the ceiling framing is a snap because it generally runs parallel to the rafters. Gable roofs without ceiling joists provide a much higher and triangular shaped ceiling inside the home. Not necessarily because it can create a vaulted ceiling and more open space. This is a short description of three methods for installing ceiling joists beneath a hip roof where rafters near the wall line don t provide much room to work.

I had done the structural engineering for a 2 story addition.

In pitched roof systems such as hip roofs and gable end roofs collar ties and ceiling joists span across the ceiling space and obstruct the view. If you want a simple roof go for a gable.

In this design the tops of the rafters attach to a load bearing ridge beam that runs along the length of the roof. Whats people lookup in this blog. A gable roof consists of two upward sloping sides that slope at the same angle and from the end look like a symmetrical triangle. Problem is the new owner wanted a cathedral look and during remodeling the contractor saw no problem in removing all the ceiling joists that basically act as tension ties and gave the owner what he wanted.

A structural ridge is the standard alternative to ceiling joists. A truly open or cathedral ceiling provides a clear unobstructed view to the underside of the roof s rafters. However the rafters on the roof need to connect from one side of the roof to the other to give it rigidity and strength and what ceiling joists do this traditionally w. With ceiling joists properly in place the roof is supported by the fact that it is made up of 4 triangles.
