Roof slope factor calculator.

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. Rise run rise run slope. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. If you know the roof pitch in degrees find the secant of the slope using a scientific calculator.

That s your roof pitch multiplier. For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. For help converting any slope from one way of expressing it to another see roof slope expressed as rise in run degrees and percentage. Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used.

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 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.

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. First convert the pitch to a slope. 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.

For example if the roof pitch is 45 then sec 45 1 414213. To obtain an accurate roof pitch measurement properly measure the rise and run. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. The maths behind this number is that it is the square root of rise run 2 1.

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