How To Determine A Roofs Pitch

This roof pitch calculator is a handy tool that will help you quickly assess what is the pitch of your roof of what length of rafters you need for your construction works.

How to determine a roofs pitch.

What is the roof pitch. To accurately calculate the area of your roof you must first determine its slope or pitch. Here s an easy safe way to determine the pitch from inside your attic. After measuring the slope estimate the roof pitch by dividing the slope by 2 if you have a simple gable roof.

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 is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. How to measure roof pitch. Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. How to calculate the pitch of a roof.

The roof pitch is the slope of the rafter. However if you have a more complex roof you may need to calculate pitch section by section. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run.

The pitch is commonly defined as the ratio of rise over run in the form of x 12. Roof pitch is used to describe the slope or angle of the roof. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.

The pitch of a roof refers to its steepness and states how many inches the slope rises for every 12 inches it runs horizontally. Although ceramic tile roofs are expensive they can have a life span of over 100 years. Shingle roofs typically have a life span of 15 30 years while membrane roofs usually last 5 15 years. Knowing the pitch of your roof is useful when designing an addition installing skylights or cutting new rake boards.

Homes and other buildings have roofs with slopes ranging from no slope or flat to very steep slopes. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. You can also use this roof slope calculator to recalculate the roof pitch from degrees to percents. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

How roof pitch is calculated. It is often compared to slope but is not exactly the same. It can be expressed in degrees or as a percentage but is often seen in ratio form such as 3 12 or 6 12. Angle the angle of a roof is the same as the roof s slope except instead of being.
