Hip Roof Ceiling Joist Layout

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.

Hip roof ceiling joist layout.

Now i can hang 2x6 ceiling joist 12 5 long from the external wall to the lvl beam. A hip roof design refers to a roof where the roof sides slope downwards from a middle peak with the rafter ends meeting the exterior walls of the house. A truly open or cathedral ceiling provides a clear unobstructed view to the underside of the roof s rafters. Surveyors and structural engineers utilise data from tables below to help calculate the correct size strength and centres of roof timbers for the required spans and loadings.

For pitched roofs flat roofs and ceiling joists. Each of the four sides of the roof slope downward there are no upright or vertical parts no gables etc on a hip roof. With premanufactured trusses or with rafters and ceiling joists commonly called stick framing. Surveyors span tables for designing roof rafters.

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. 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. The angles are basic and even the ceiling framing is a snap because it generally runs parallel to the rafters. There are two common ways of framing the roof of a house.
