- Starting at the peak of your gable roof, measure down 36" along each side of your gable and make a mark.
- Using a metal measuring tape, measure the distance horizontally (across) from mark to mark. Use the online Roof...
How do you measure a gable roof?
Tape measure. Math compass. The gable roof pitch is the term used to describe the angle between the horizontal of the ceiling and wall line and the diagonal angle of the roof joists. Gable roof pitch can also be given as ration, described as the rise over the run.
How do you measure the pitch of a roof?
Once you're safely on your roof, measure 1-foot up from the base, which will give you the run. Then place the spirit level at the 1-foot marker, and once it is even, measure from the bottom of the level to the top of your roof. This will give you the rise. For example, if your rise is 6 inches, then your roof pitch will be 6/12.
What is a gable roof pitch?
The gable roof pitch is the term used to describe the angle between the horizontal of the ceiling and wall line and the diagonal angle of the roof joists. Gable roof pitch can also be given as ration, described as the rise over the run.
How do you cut roof pitch for a gable roof?
With printed pitch guide at arm's length, select the pitch lines that closest match your gable's roof pitch. 3. Cut Along Selected Pitch Lines Cut along the edge of the selected pitch lines.
What is the standard pitch of a gable roof?
30-35 degreesGable roofs provide excellent drainage, particularly when designed at an ideal pitch of 30-35 degrees. Subsequently, there is sufficient fall for water runoff and snow when gables are designed at the ideal pitch.
How is roof pitch measured?
The angle, or pitch, of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally. For example, a roof that rises 6 inches for every 12 inches of horizontal run has a 6-in-12 pitch.
What is the most common roof pitch?
between 4/12 and 9/12Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes.
What pitch is 45 degrees?
12/12 pitchA 12/12 pitch roof has a pitch angle of 45°.
What does a 4/12 pitch roof mean?
A roof that rises 4 inches for every 1 foot or 12 inches of run is said to have a "4 in 12" slope. If the rise is 6 inches for every 12 inches of run, then the roof slope is "6 in 12." The slope can be expressed numerically as a ratio.
What does a 6 12 roof pitch mean?
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
What does a 3/12 roof pitch mean?
A 3/12 roof pitch angle is about 14°, so on and so forth. 4/12 is quite typical. Anything under 3/12 is a low pitch roof. Anything above 6/12 is a steep roof pitch since it becomes harder to walk on the roof.

How to find the pitch of a gable roof?
For a simple gable roof, the span (wall to wall) will be twice the size of the run (wall to ridge, horizontally). Divide the slope by two to get the pitch. For a roof with the ridge above one wall, the span is the same as the run. The slope is the same as the pitch.
How to calculate roof pitch?
Before you calculate roof pitch, you'll need to measure the slope of your roof. The easiest way to do this is by accessing a rafter in your attic if you can . If you can’t get to your attic, you can measure slope on your rooftop as long as it’s safe to go up there. After measuring the slope, estimate the roof pitch by dividing the slope by 2 if you have a simple gable roof. However, if you have a more complex roof, you may need to calculate pitch section-by-section. For more on calculating roof pitch and understanding how pitch and slope are different, read on!
How to find the slope of a roof?
1. Access a rafter. Measuring from the underside of the roof is usually the most accurate way to find the slope, since there is no roofing material to make an uneven surface. Any of the following will give you a good measurement: A rafter in the attic. The overhang of a rafter at the end of the roof.
How many feet is a roof pitch?
For example, if a roof is 32 feet from wall to wall and the ridge is 8 feet above the walls, the pitch has an 8 to 32 pitch, simplifying to "1 to 4" or "1/4". Find the pitch. If you do need to calculate the pitch, an estimate or shortcut is usually more practical than measuring the roof's overall dimensions.
What is the slope of a roof?
For example, if one side of the roof rises by 8 inches for every 12 inches of horizontal distance, it has a slope of "8 in 12" or "8:12."
What is the slope of 4 inches?
For example, if you find 4 inches of height with the tape measure at the 12 inch mark on the level, your slope is 4:12 or "4 in 12."
What is the correct term for the ratio of vertical to horizontal distance on a particular plane of the roof?
Slope is the correct term for the ratio of vertical to horizontal distance on a particular plane of the roof. Even carpenters often use the terms slope and pitch interchangeably. For example, if one side of the roof rises by 8 inches for every 12 inches of horizontal distance, it has a slope of "8 in 12" or "8:12.".
