Slope Roof To Building

The way pitch also known as roof slope is measured is rise over run.

Slope roof to building.

Roof pitch refers to the slope which the rafter creates. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. Squaring building lines example the picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.

This means for every 12 horizontal units the roof must rise a minimum of one fourth vertical unit. The roofslope auxiliary sloping compound provides a quick and easy way to fill in low spots on flat roofs and achieve positive slope to aid in proper drainage. This patented technology provides a durable finish with the ability to match existing roofing compositions. Roof pitch is the measurement of roof steepness.

In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally. Coal tar built up roofs however can have a design roof slope of 1 8 12 1 percent but no less. Built up roofs must have a design roof slope of 1 4 12 or greater 2 slope. A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible.
