Sloped Roof To Truss

Roof slope style.

Sloped roof to truss.

The maths behind this number is that it is the square root of rise run 2 1. The run always remains constant at 12 inches. Roof truss designs king truss. Pitch slope the pitch or slope is the incline of the roof expressed as a fraction describing the rise over the run.

The rise will be the elevation change over the 12 inches. Conventional slope roof range between 4 in 12 and 8 in 12. A low slope roof is anywhere from 2 in 12 to 4 in 12. A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper.

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. Select an angle of slope away from a house into an area with good drainage and complementary to an existing house or other building. A flat roof has a slope of 2 in 12 or less. A mono truss is a one sloped truss that forms a right angle triangle.

This is the most traditional classic design of roof truss and probably the one that first springs to mind when timber trusses are mentioned. Measure the outline of the structure to be roofed with a tape measure or get dimensions from a house plan. 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. Use prefabricated mono trusses for the easiest and best framing on a single slope roof.

That is the roof s rise. The run or the base number is 12 inches. It s often used for sheds garages or extension of an existing roof.
