1. Understanding Roof Pitch
Roof pitch is the angle of inclination of the roof, set to the most appropriate ratio for the structure you are building to ensure both aesthetic appeal and to prevent water pooling, leading to roof leaks during rainy weather.
Depending on the type of roof, the pitch of the corrugated iron roof will vary. The steeper the roof, the faster water drainage, but this also means using more roofing materials than usual, resulting in increased construction costs. A reasonable pitch for corrugated iron roofs is around 10%.
2. Standards for Roof Pitch in Factories, Residential Homes, and Villas
To prevent water pooling and leaks into the structure during rain, the minimum slope of corrugated iron roofs is 10%, but it varies depending on the structure.
3. Formula for Calculating Suitable Roof Pitch
There are various materials used for producing corrugated iron roofs such as fiber-cement roofs, tile roofs, etc., so each material will have a different slope, specifically:
- Fiber-cement roofs: 30 - 40%.
- Tile roofs: 15 - 20%.
- Steel-reinforced concrete roofs: 5 - 8%.
- Tile roofs: 50 - 60%.
For prefabricated workshops, the minimum slope of corrugated iron roofs ranges from 8 - 10%, typically built from 10 - 30%. Furthermore, you need to understand the weight of the roof to easily calculate the necessary parameters.
4. How to Calculate Roof Pitch, Slope Angle
Firstly, you need to grasp the units of roof pitch, slope angle:
- Roof pitch: Unit is %.
- Slope angle: Unit is degree.
* Calculating roof slope
It's easy to see that the roof slope is calculated using the formula: i = H/L x 100.
Where:
- i represents the roof slope.
- H stands for height.
- L represents length.
For example: If we have a roof length of 25m and a height of 2.8m, then the roof slope equals 2.8/25 x 100 = 11.2 (%).
* Calculating roof pitch angle
To calculate the roof pitch angle, you apply the formula:
Where:
- H represents the height.
- L stands for the length.
For instance: If the roof length is 25m and the roof height is 2.8m, then
Here's how to calculate the roof slope, so you can determine the most suitable roof slope for your construction project.
In addition to checking the roof slope, you also need to check steel shapes in construction to choose the appropriate steel shape for your construction project. This way, your construction project will be sturdy and durable over time.
