How to build a mono pitch roof truss.

The run or the base number is 12 inches. Pitch slope the pitch or slope is the incline of the roof expressed as a fraction describing the rise over the run. For example a slope of 6 12 means for every 12 inches of horizontal distance the slope of the roof will rise 6 inches vertically. Measure 23 1 4 inches in and draw another line for the outside of the second truss.

This online truss calculator will determine the all in cost of your truss based on key inputs related to the pitch width and overhang of your roof. Mark truss locations on the front and back wall caps of the structure. This is the distance between trusses. Then plan for the bottom chord of the truss to be 1 4 inch longer than the floor of the structure.

A mono truss is a one sloped truss that forms a right angle triangle. The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases. It s often used for sheds garages or extension of an existing roof. The rise will be the elevation change over the 12 inches.

This sort of mono pitch construction is known as lean to roof. The standard roof truss spacing is 2. Difference in slope between the top and bottom chords is at least 3 12 or the bottom chord pitch is no more than half the top chord pitch. In such a house although the main roofing comes with a flat ceiling the mono pitched part of the roofing would have a slant.

To build a simple wood truss start by measuring the length and height of the structure you re reinforcing to determine how big your truss should be. A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper. Measure 1 1 2 inches in from one side and draw a line with the speed square to mark the location for the first mono truss. One needs to place the mono pitch roof at a height which is lower than that of the height of the ceiling of the main construction.

Get on a ladder with a tape measure speed square and marker. It will use the current cost of wooden rafters based on the average price found at home improvement stores. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
