Roof slope factor calculator.
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.
The maths behind this number is that it is the square root of rise run 2 1.
This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.
First convert the pitch to a slope.
Using a tape measure make a pencil mark 12 inches from the end of a carpenter s level.
Rise run rise run slope.
Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used.
For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.
For example if the roof pitch is 45 then sec 45 1 414213.
That s your roof pitch multiplier.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
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.
If you know the roof pitch in degrees find the secant of the slope using a scientific calculator.
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.
To do this simply convert the rise and run as a fraction to a decimal form eg.
Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run.
To accurately calculate the area of your roof you must first determine its slope or pitch.
For help converting any slope from one way of expressing it to another see roof slope expressed as rise in run degrees and percentage.
To use this you must take the required measurements so you can input them in the required fields.
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.
