Roof Pitch Calculator – Rafter Calculator – Roof pitch to angle convertor

Here’s a simple roof pitch calculator that help users estimate roof pitch, rafter slope, or roof slope. The Calculator ask for values for Rise and run of roof. The calculator give result of roof pitch, slope in percentage, and angle in degrees. Here’re the formulas to use:

Roof Pitch = rise / (run/12)

Roof slope = (rise / run)*100

Roof Angle = inverse tan of (Rise / Run)

Sure! Here is the HTML code for a simple calculator that asks for the rise and run of a roof and displays the roof pitch, slope in percentage, and angle in degrees:

Rise:
Run:

Roof Pitch:
Slope: %
Angle: degrees

How to use this roof calculator?

To use this calculator, simply enter the values for the rise and run of the roof in the input fields, and then click the “Calculate” button. The calculator will then display the roof pitch, slope in percentage, and angle in degrees.

What is a roof pitch?

Roof pitch is a measure of the slope of a roof. It is the vertical rise of a roof over a horizontal length, typically measured in inches per foot. Roof pitch is important because it determines the amount of water and snow that a roof can shed, as well as the type of roofing material that can be used. In general, steeper roofs are better at shedding water and snow, but they may also require more expensive materials and labor to install.

How to calculate the roof pitch?

There are several ways to calculate roof pitch.

One common method is to measure the vertical rise of the roof over a horizontal distance of 12 inches.

For example, if the rise of the roof is 6 inches and the horizontal distance is 12 inches, the roof pitch would be 6/12, or a pitch of 1/2.

Another method of calculating roof pitch is to use a level and a tape measure. To do this, hold the level against the roof at the point where you want to measure the pitch. Then, measure the horizontal distance from the level to the roof at the highest point of the roof. This distance is the rise of the roof. Divide the rise by the horizontal distance to determine the roof pitch.

Types of roof pitch or slope

There are several different types of roof pitch, including low pitch, medium pitch, and high or steep pitch. Low pitch roofs have a slope of less than 3/12, and are typically found on ranch-style houses or other low-slung buildings. Medium pitch roofs have a slope of 3/12 to 6/12, and are common on most residential houses. High or steep pitch roofs have a slope of greater than 6/12, and are typically found on commercial buildings or houses in areas with heavy snowfall.

Importance of roof pitch

The importance of roof pitch depends on the climate and the type of roofing material being used. In areas with heavy snowfall, steeper roofs are necessary to prevent snow from accumulating and causing damage to the roof or the structure of the building. In hot, dry climates, low pitch roofs may be more suitable because they allow for better ventilation and heat dissipation. It is important to choose the appropriate roof pitch for your location and needs to ensure that your roof is functional and durable.
