How To Build A Vaulted Roof

A dramatic cathedral ceiling makes a strong statement in a home s interior but make sure to follow the best practices to eliminate mold and wood rot while also saving money on lumber and materials.

How to build a vaulted roof.

When planning for vaulted ceilings in new home construction most architects use a scissors truss which is designed according to the angle of the roof slope that has been planned by the homeowner or architect. For new construction a home with a vaulted ceiling requires special trusses that must be built off site. There are several options for installing insulation in a vaulted ceiling among the easiest options is to install rigid insulation sheets over the rafters which not only provides insulation but also the structural function of enclosing the roof. Special roof trusses are required.

I needed to get the lvl straight and true so i put up the roof rafters very 8. A vaulted roof structure opens the space below for stylistic reasons or for the addition of an attic or loft area. Most construction teams can easily swing and set manufactured trusses but fewer can build a good solid on site truss especially of the type needed for framing vaulted ceilings. This also allows you to save on lumber by using 2.

Of the four basic roof shapes shed flat gable and hip only the flat roof is. These horizontal framing members tie a building s outer walls together and resist the outward force exerted by the roof rafters in conventional framing. This helped but then the rain came. I worked until i couldn t work anymore.

Without joists the walls can bow outward and the roof ridge line may sag. The fabricator then builds the vaulted ceiling which is about half the slope of the exterior roof beneath the scissor truss components. Vaulted ceilings can be constructed by either stick framing which means attaching each joist and rafter individually or by setting roof trusses that come engineered from a truss manufacturer. For example spray foam insulation helps create an air tight seal that eliminates the need for ridge and soffit venting.
