Proper Way To Write The Pitch Of A Roof

How to measure a roof s pitch.

Proper way to write the pitch of a roof. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Pitch is the term used to describe the angle slope or slant of your roof. Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run.

As aforementioned there is no standard pitch of a roof. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. The pitch of your roof is determined by the measurement of the vertical rise by the horizontal run. The roof is one of the most important elements of any building or structure which provides protection from external environmental influences such as winds snowing raining etc.

So let s say a roof rises 6 inches for every 12 inches in depth towards the peak. First measure 12 inches from one end of the level and make a mark. Roof pitch defined and explained. Roof pitch is simply the slopecreated by the rafter.

That is to say the roof pitch expressed as a ratio tells you how many inches the roof rises for every 12 inches of depth. Or the colon can replace the slash as in 2 12 or 7 12. Keep in mind that pitch will determine the material required to meet florida building code as well as the material quantities needed. Roof pitch is often expressed as a ratio between rise and run in the form of x 12.

However you can only use this pitch with built up roofing or specialized synthetic roofing. It requires the proper calculation of the angle of the roof pitch. 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.

The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. 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. The pitch of a roof is its vertical rise over its horizontal span. Roof pitch designations are comprised of two numbers indicating a ratio.
