Sloped Roof To Truss

Roof truss designs king truss.

Sloped roof to truss.

Roof slope style. The run always remains constant at 12 inches. Measure the outline of the structure to be roofed with a tape measure or get dimensions from a house plan. This is the most traditional classic design of roof truss and probably the one that first springs to mind when timber trusses are mentioned.

Pitch slope the pitch or slope is the incline of the roof expressed as a fraction describing the rise over the run. A mono truss is a one sloped truss that forms a right angle triangle. A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof. The run or the base number is 12 inches.

A king post then runs from the apex to the centre of the tie beam. The maths behind this number is that it is the square root of rise run 2 1. A low slope roof is anywhere from 2 in 12 to 4 in 12. Use prefabricated mono trusses for the easiest and best framing on a single slope roof.

There are two main categories of roofing. Conventional slope roof range between 4 in 12 and 8 in 12. 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. A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper.

A flat roof has a slope of 2 in 12 or less. It consists of a triangle formed from a tie beam at the base and two sloping rafters joined at the top. That is the roof s rise.
