Roof Picth Slope

So if your roof rises 4 inches for every 12 inches of horizontal length then the pitch of your roof is expressed as 4 12.

Roof picth slope.

It determines how many inches the roof should rise for every 12 inches expanding on the horizontal side. However most often a ratio of pitch also fraction is slang used for the more useful slope of rise over run of just one side half the span of a dual pitched roof. Roof pitch is the degree of building s roof slope. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

Some people prefer high pitches and some other choose low roof pitches each has their own advantages and disadvantages. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

If a roof increases in height by four inches for every foot of horizontal run it is considered to have a 4 in 12 pitch or just a 4 pitch talk in terms of pitches and you will always be understood in the roofing universe. The pitch of a roof is its vertical rise over its horizontal span. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Roof pitch is the measurement of roof steepness.

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. Roof pitch is simply the slopecreated by the rafter. For example a roof with a pitch of 2 12 3 12 will work best with 3 tab shingles the roofing most commonly found on homes in jacksonville. So the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally.

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. A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible. 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. Understanding your roof s pitch and slope by knowing the pitch of your roof you will know what type of products can be used and the best ways to go about applying them.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Roof pitch refers to the slope which the rafter creates.
