Roof pitch is a term describing how steep or flat your roof slope is. Contemporary houses often have flat roofs which shouldn. Greek says one must keep rafter length in range of 1 9 to 1 7 th of span but as per roman style the standard dimensions are kept about 1 3 to 2 9 th of span with an angle of 23 to 24 degree. Roof pitch angle and slope factor charts.

If this isn t practical then perform the same measurement on the underside of the roof. Usually average roof pitch is determined using the same roof length method. Roof pitch calculator results explained. Angle the angle of a roof is the same as the roof s slope except instead of being.

A mono truss is a one sloped truss that forms a right angle triangle.

Girder trusses are designed to carry additional loads other than standard roof loads. Common or standard trusses are symmetrical and have standard four inch heels. These loads can be other trusses that attach by sitting on top of the girder. This is the distance between trusses.

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. A truss with the same pitch and heel on both sides and a peak at the center is called a common truss. We included a roof pitch chart below the 7 12 example image and the calculator below that.
