Figuring out slope of roof.

The minimum roof pitch for shedding snow is around 30 or a 6 12 or 7 12 slope although this is not a definite as the material of your roof the direction of the snow and wind are some factors that can affect whether or not snow will slide as roofs of as little as 10 have been reported to shed snow. You will need to express this size in terms of square feet. Access one of the rafters then take the measurement this way. If you are trying hard to work out how to figure roof pitch measurements the calculator takes away all of those problems for you more or less instantly.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. To avoid this problem from occurring you should always look for a roof pitch calculator to help you take things a step further. Here s an easy safe way to determine the pitch from inside your attic. Knowing the pitch of your roof is useful when designing an addition installing skylights or cutting new rake boards.

The first step in a free roofing estimate is measuring the roof dimensions. It is often compared to slope but is not exactly the same. Angle the angle of a roof is the same as the roof s slope except instead of being. 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.

Common roof pitches and equivalent grade degree and radian angles. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. The most precise way to find the roof s slope is by measuring it from the underside. Calculate the roof slope.

Roof pitch calculator results explained. How to measure roof pitch. Most roof s have a pitch in the 4 12 to 9 12 range. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.

Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance. For example if your tape measure found a 6 inch vertical distance to the 12 inch mark on your level the slope is 6 12 or 6 in 12.

Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure. Either way let s see how you can calculate the slope of a roof without using a roof slope calculator.
