Pitched Roof Without Trusses

Pitch measurement method 1.

Pitched roof without trusses.

Make sure the pitch of the trusses is the pitch that you want for your new roof. Without consulting a structural engineer. Angle the angle of a roof is the same as the roof s slope except instead of being. Girder trusses are designed to carry additional loads other than standard roof loads.

Roof pitch calculator results explained. A common house roof pitch is 5 by 12 which means it slopes up from the wall at 5 inches per foot. Pitched roof types explained cut and truss roofs. 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.

What is a pitched roof. Premade trusses will form the skeleton of your new roof above your old roof. 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. If this distance measures 4 inches you have a 4 in 12 pitch.

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. Premade roofing trusses will be easier and take less time than installing a stick built roof. 8 inches and you have an 8 in 12 pitch. The illustration to the right shows a typical truss for a simple duo ridge roof.

A truss roof. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss. The trusses are an engineered timber web that when constructed form the complete roof system.
