Sloped Roof Truss

Select an angle of slope away from a house into an area with good drainage and complementary to an existing house or other building.

Sloped roof truss.

The maths behind this number is that it is the square root of rise run 2 1. Use prefabricated mono trusses for the easiest and best framing on a single slope roof. It s often used for sheds garages or extension of an existing roof. The more complex the truss framework is the greater quantity of these joints will be required.

A mono truss is a one sloped truss that forms a right angle triangle. If desiring a clearspan the overall height of the roof trusses should be no more than 12 feet. Conventional slope roof range between 4 in 12 and 8 in 12. That is the roof s rise.

These steel joints are needed to support the overall truss. 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. The vertical rise of the top chord per 12 horizontal inches is the roof pitch or slope. The run or the base number is 12 inches.

Trusses are the more modern engineered method for supporting a roof. Roof pitch calculator results explained. A low slope roof is anywhere from 2 in 12 to 4 in 12. Angle the angle of a roof is the same as the roof s slope except instead of being.

The rise will be the elevation change over the 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 4 12 pitch means 4 inches of rise in 12 inches of run. Measure the outline of the structure to be roofed with a tape measure or get dimensions from a house plan.

Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. Roof slope style. Truss a network of pre made usually double sloped beams connected or bridged by a bottom beam or brace. 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.

There are two main categories of roofing. A flat roof has a slope of 2 in 12 or less. The same thing is true for the bridge of the truss. The run always remains constant at 12 inches.

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. The common truss pictured above is an a frame that fits double sloped houses. A mono truss roof allows for more sunlight and visual space proper drainage and relatively cheaper.
