Pitched Roof Without Trusses

Without consulting a structural engineer.

Pitched roof without trusses.

Pitched roof types explained cut and truss roofs. A pitched roof construction is the classic old school way of roof construction. Girder trusses are designed to carry additional loads other than standard roof loads. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss.

Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Roof pitch calculator results explained. Pitch measurement method 1. These loads can be other trusses that attach by sitting on top of the girder or they may attach to the side of the girder using truss hangers.

The illustration to the right shows a typical truss for a simple duo ridge roof. If this distance measures 4 inches you have a 4 in 12 pitch. A truss roof is made up of a number of factory made frames or trusses each of which which combine the joist rafter and struts. Premade roofing trusses will be easier and take less time than installing a stick built roof.

A truss roof. 8 inches and you have an 8 in 12 pitch. Make sure the pitch of the trusses is the pitch that you want for your new roof. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof.

What is a pitched roof. A common house roof pitch is 5 by 12 which means it slopes up from the wall at 5 inches per foot. Premade trusses will form the skeleton of your new roof above your old roof.
