The run or the base number is 12 inches.
Sloped roof to truss.
A mono truss is a one sloped truss that forms a right angle triangle.
Roof slope style.
A flat roof has a slope of 2 in 12 or less.
Select an angle of slope away from a house into an area with good drainage and complementary to an existing house or other building.
The maths behind this number is that it is the square root of rise run 2 1.
Conventional slope roof range between 4 in 12 and 8 in 12.
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.
This is the most traditional classic design of roof truss and probably the one that first springs to mind when timber trusses are mentioned.
The run always remains constant at 12 inches.
Use prefabricated mono trusses for the easiest and best framing on a single slope roof.
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.
A low slope roof is anywhere from 2 in 12 to 4 in 12.
It consists of a triangle formed from a tie beam at the base and two sloping rafters joined at the top.
A king post then runs from the apex to the centre of the tie beam.
There are two main categories of roofing.
That is the roof s rise.
A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper.
Roof truss designs king truss.
