Calculating your roof pitch is a comparatively easy course of. All you want is just a few fundamental instruments and just a little little bit of math. On this article, we’ll stroll you thru the steps concerned in calculating your roof pitch so to get began in your challenge with confidence.
As soon as you understand your roof pitch, you can begin searching for roofing supplies and planning your challenge. So let’s get began!
Learn how to Calculate Roof Pitch
Calculating your roof pitch is a straightforward course of that requires just a few fundamental instruments and just a little little bit of math.
- Measure roof rise
- Measure horizontal run
- Use Pythagorean theorem
- Calculate roof slope
- Convert to levels
- Use pitch ratio
- Frequent pitch varieties

As soon as you understand your roof pitch, you can begin searching for roofing supplies and planning your challenge.
Measure Roof Rise
The roof rise is the vertical distance from the horizontal aircraft of the roof to the best level of the roof. To measure the roof rise, you will have a ladder, a tape measure, and a degree.
1. Arrange your ladder. Place the ladder in opposition to the aspect of your home, ensuring that it’s secure and safe. Lengthen the ladder to a top that’s barely above the best level of your roof.
2. Connect the extent to the ladder. Place the extent horizontally on the ladder, ensuring that it’s degree with the bottom. You need to use a bungee twine or a rope to safe the extent to the ladder.
3. Measure the gap from the extent to the best level of the roof. Use the tape measure to measure the gap from the underside of the extent to the best level of the roof. That is the roof rise.
4. Repeat the method on the opposite aspect of the roof. The roof rise must be the identical on either side of the roof. If it’s not, then you will have to search out the typical of the 2 measurements.
After you have measured the roof rise, you possibly can transfer on to the following step, which is to measure the horizontal run.
Measure Horizontal Run
The horizontal run is the horizontal distance from the sting of the roof to the middle of the ridge board. To measure the horizontal run, you will have a tape measure and a helper.
1. Arrange your tape measure. Lengthen the tape measure to the complete size of the roof. Have your helper maintain one finish of the tape measure on the fringe of the roof, whilst you maintain the opposite finish on the middle of the ridge board.
2. Measure the gap. Learn the tape measure to find out the horizontal run. That is the gap from the sting of the roof to the middle of the ridge board.
3. Repeat the method on the opposite aspect of the roof. The horizontal run must be the identical on either side of the roof. If it’s not, then you will have to search out the typical of the 2 measurements.
4. If in case you have a gable roof, additionally, you will must measure the size of the gable finish. That is the horizontal distance from the sting of the roof to the height of the gable. You need to use the identical technique as you used to measure the horizontal run.
After you have measured the horizontal run and the gable finish (if relevant), you possibly can transfer on to the following step, which is to calculate the roof slope.
Use Pythagorean Theorem
The Pythagorean theorem states that in a proper triangle, the sq. of the hypotenuse is the same as the sum of the squares of the opposite two sides. We will use this theorem to calculate the roof slope, which is the angle at which the roof rises from the horizontal.
1. Draw a proper triangle. Think about a proper triangle with the roof rise because the vertical aspect, the horizontal run because the horizontal aspect, and the roof slope because the hypotenuse.
2. Sq. the roof rise and the horizontal run. Multiply the roof rise by itself to get the sq. of the roof rise. Multiply the horizontal run by itself to get the sq. of the horizontal run.
3. Add the squares of the roof rise and the horizontal run. Add the sq. of the roof rise and the sq. of the horizontal run to get the sq. of the hypotenuse.
4. Take the sq. root of the sq. of the hypotenuse. This gives you the size of the hypotenuse.
The roof slope is the angle between the hypotenuse and the horizontal. You need to use a calculator to search out the angle. As soon as you understand the roof slope, you possibly can convert it to levels or use it to calculate the roof pitch.
sensibly
Convert to Levels
The roof slope is usually expressed in levels. To transform the roof slope from radians to levels, you need to use the next system:
- Multiply the roof slope by 180.
- Divide the end result by π.
For instance, if the roof slope is 0.5 radians, then the roof slope in levels can be:
0.5 radians * 180 / π = 28.6 levels
Use Pitch Ratio
The roof pitch will also be expressed as a ratio. The pitch ratio is the ratio of the vertical rise of the roof to the horizontal run of the roof. For instance, a roof with a pitch ratio of 4:12 has a vertical rise of 4 inches for each 12 inches of horizontal run.
- To calculate the roof pitch ratio, divide the roof rise by the horizontal run.
- Simplify the fraction, if doable.
For instance, if the roof rise is 8 inches and the horizontal run is 12 inches, then the roof pitch ratio can be:
8 inches / 12 inches = 2/3
Frequent Pitch Sorts
The most typical roof pitches fall between 1/4:12 and 12:12. A roof with a pitch of 1/4:12 has a really slight slope, whereas a roof with a pitch of 12:12 has a really steep slope.
The next are a number of the most typical roof pitch varieties:
- 1/4:12 to 2:12: It is a very low pitch, and it’s typically used on sheds and different outbuildings.
- 3:12 to six:12: It is a average pitch, and it’s typically used on residential houses.
- 7:12 to 12:12: It is a steep pitch, and it’s typically used on industrial buildings and church buildings.
The kind of roofing materials that you simply select may even have an effect on the roof pitch. For instance, asphalt shingles can be utilized on roofs with pitches as little as 2:12, whereas steel roofing can be utilized on roofs with pitches as steep as 12:12.
You will need to examine your native constructing codes earlier than you begin building in your roof. Some areas have restrictions on the roof pitch that’s allowed.
Examine Native Constructing Codes
Earlier than you begin building in your roof, it is very important examine your native constructing codes. Some areas have restrictions on the roof pitch that’s allowed. These restrictions are in place for security causes. A roof that’s too steep will be harmful to work on, and it will also be extra inclined to wind harm.
To search out out the roof pitch restrictions in your space, you possibly can contact your native constructing division. They may be capable to give you a duplicate of the constructing code, which can include the data you want.
In case you are planning to construct a roof with a pitch that’s steeper than the utmost allowed by the constructing code, you will have to use for a variance. A variance is a allow that lets you construct one thing that doesn’t meet the necessities of the constructing code. To use for a variance, you will have to submit a request to the native constructing division. The constructing division will then evaluate your request and determine whether or not or to not grant you a variance.
You will need to notice that constructing codes can change over time. Subsequently, it’s at all times a good suggestion to examine the most recent constructing code earlier than you begin building in your roof.
