Are you planning to switch or restore your roof? Earlier than you begin, you will must know your roof pitch. That is the angle at which your roof rises from the horizontal, and it is an necessary think about figuring out the kind of roofing supplies you should utilize and the price of your undertaking.
Calculating your roof pitch is a comparatively easy course of. All you want is just a few fundamental instruments and a bit little bit of math. On this article, we’ll stroll you thru the steps concerned in calculating your roof pitch to be able to get began in your undertaking with confidence.
As soon as you realize your roof pitch, you can begin looking for roofing supplies and planning your undertaking. So let’s get began!
Easy methods to Calculate Roof Pitch
Calculating your roof pitch is an easy course of that requires just a few fundamental instruments and a bit little bit of math.
- Measure roof rise
- Measure horizontal run
- Use Pythagorean theorem
- Calculate roof slope
- Convert to levels
- Use pitch ratio
- Frequent pitch sorts

As soon as you realize your roof pitch, you can begin looking for roofing supplies and planning your undertaking.
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 want a ladder, a tape measure, and a stage.
1. Arrange your ladder. Place the ladder towards the facet of your own home, ensuring that it’s steady and safe. Prolong the ladder to a peak 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 stage with the bottom. You should use a bungee wire or a rope to safe the extent to the ladder.
3. Measure the space from the extent to the best level of the roof. Use the tape measure to measure the space 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 facet of the roof. The roof rise must be the identical on either side of the roof. If it’s not, then you will want to seek out the typical of the 2 measurements.
Upon getting measured the roof rise, you may 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 want a tape measure and a helper.
1. Arrange your tape measure. Prolong 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 space. Learn the tape measure to find out the horizontal run. That is the space from the sting of the roof to the middle of the ridge board.
3. Repeat the method on the opposite facet of the roof. The horizontal run must be the identical on either side of the roof. If it’s not, then you will want to seek out the typical of the 2 measurements.
4. When you’ve got 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 should use the identical technique as you used to measure the horizontal run.
Upon getting measured the horizontal run and the gable finish (if relevant), you may 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 are able to 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 facet, the horizontal run because the horizontal facet, 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 will provide you with the size of the hypotenuse.
The roof slope is the angle between the hypotenuse and the horizontal. You should use a calculator to seek out the angle. As soon as you realize the roof slope, you may convert it to levels or use it to calculate the roof pitch.
sensibly
Convert to Levels
The roof slope is commonly expressed in levels. To transform the roof slope from radians to levels, you should utilize the next method:
- Multiply the roof slope by 180.
- Divide the outcome by π.
For instance, if the roof slope is 0.5 radians, then the roof slope in levels could be:
0.5 radians * 180 / π = 28.6 levels
Use Pitch Ratio
The roof pitch may 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 potential.
For instance, if the roof rise is 8 inches and the horizontal run is 12 inches, then the roof pitch ratio could be:
8 inches / 12 inches = 2/3
Frequent Pitch Varieties
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 among the most typical roof pitch sorts:
- 1/4:12 to 2:12: This can be a very low pitch, and it’s typically used on sheds and different outbuildings.
- 3:12 to six:12: This can be a average pitch, and it’s typically used on residential properties.
- 7:12 to 12:12: This can be a steep pitch, and it’s typically used on industrial buildings and church buildings.
The kind of roofing materials that you just 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 verify your native constructing codes earlier than you begin development in your roof. Some areas have restrictions on the roof pitch that’s allowed.
Test Native Constructing Codes
Earlier than you begin development in your roof, it is very important verify 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 could be harmful to work on, and it may also be extra inclined to wind injury.
To search out out the roof pitch restrictions in your space, you may contact your native constructing division. They may have the ability to offer you a replica of the constructing code, which can include the data you want.
If you’re planning to construct a roof with a pitch that’s steeper than the utmost allowed by the constructing code, you will want to use for a variance. A variance is a allow that means that you can construct one thing that doesn’t meet the necessities of the constructing code. To use for a variance, you will want 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 word that constructing codes can change over time. Due to this fact, it’s all the time a good suggestion to verify the most recent constructing code earlier than you begin development in your roof.
