Roof Slope Factor Calculator

That s your roof pitch multiplier.

Roof slope factor 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. To use this you must take the required measurements so you can input them in the required fields. Rise run rise run slope. 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.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. For help converting any slope from one way of expressing it to another see roof slope expressed as rise in run degrees and percentage. For example if the roof pitch is 45 then sec 45 1 414213.

Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level. 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. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

To accurately calculate the area of your roof you must first determine its slope or pitch. Here are the steps to follow for the roof angle calculator. Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used. To obtain an accurate roof pitch measurement properly measure the rise and run.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Then you ll be able to measure slope from an unfinished attic space under the roof. 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. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.

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. To do this simply convert the rise and run as a fraction to a decimal form eg. Outside of the u s a degree angle is typically used.
