Slope Ridge Roof

A roof with one slope historically attached to a taller wall.

Slope ridge roof.

In traditional house framing also called stick framing a basic roof frame consists of opposing pairs of sloping rafters that meet at their top ends at a ridge board or ridge beam. Some sources consider low slope to include 3 12 pitch roofs. Roof pitch or slope is the angle of the roof surface above the flat or horizontal plane. A 4 12 slope is enough to accommodate water runoff but is not suitable for regions that are affected by heavy snowfall.

Ondura 5259 4 in x 39 5 in cellulose fiber asphalt roof panel ridge caps. 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. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

Slopes greater than 18 12 are found on a frame roofs and some mansard style. This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof.

The top end of each rafter is cut at an angle so that it meets flush with one broadside of the ridge board and the ridge is sandwiched between the rafters. Low slope roofs are from 0 to 3 12 in pitch. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. See low slope roofing.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. For pricing and availability.
