Roof Slope Factor Calculator

Then you ll be able to measure slope from an unfinished attic space under the roof.

Roof slope factor calculator.

Here are the steps to follow for the roof angle calculator. Roof pitch calculator results explained 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 roof pitch calculator or roof slope calculator is a simple easy to understand tool to use when you need to perform construction work in your home. First convert the pitch to a slope.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. That s your roof pitch multiplier. Outside of the u s a degree angle is typically used.

Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level. Enter 6 into the calculator slope factor 1 1180 multiply the roof length by the gable wall length 40 24 960 multiply this amount by the slope factor 960 1 1180 1073 28 the area of this roof 1073 3 sq. A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof. To do this simply convert the rise and run as a fraction to a decimal form eg.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Rise run rise run slope. To use this you must take the required measurements so you can input them in the required fields. For example if the roof pitch is 45 then sec 45 1 414213.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope.

For help converting any slope from one way of expressing it to another see roof slope expressed as rise in run degrees and percentage. The maths behind this number is that it is the square root of rise run 2 1. To accurately calculate the area of your roof you must first determine its slope or pitch.
