How to calculate the tilt of the roof

When it comes to building or renovating a roof, one of the most important aspects to be considered is the inclination. The correct tilt of the roof is essential to ensure proper drainage of rainwater and avoid problems such as infiltrations and structural damage.

Why is the tilt of the roof important?

The tilt of the roof is important for several reasons. First, it determines the way rainwater will be drained. If the roof does not have the proper inclination, water can accumulate and cause infiltration, damaging the structure and causing moisture problems inside the house.

In addition, the tilt of the roof also influences the durability of the material used. Inadequate tilt roofs may suffer from dirt, moss and algae, which can decrease their service life.

how to calculate the tilt of the roof?

There are different methods for calculating roof tilt, but one of the most common is the use of a simple formula:

inclination (%) = (height/length) x 100

To use this formula, you will need to measure the height of the roof (from the lowest point to the highest point) and the roof length (from the edge to the highest point). Then simply replace the values ​​in the formula and calculate the slope in percentage.

For example, if the roof height is 2 meters and the length is 10 meters, the slope will be:

inclination (%) = (2 /10) x 100 = 20%

Another common method for calculating roof tilt is the use of a bubble level. Just position the level on one of the tiles and check the indicated slope.

What is the ideal tilt for the roof?

The ideal tilt for the roof varies according to the type of tile used and the region where construction is located. In general, it recommends a minimum slope of 10% (ie a 10 centimeter elevation each meter long).

However, in regions with a high incidence of rainfall, it is recommended to increase the inclination to ensure more efficient drainage. In areas with drier climate, the slope can be slightly smaller.

Conclusion

The tilt of the roof is a fundamental aspect to be considered in any construction or renovation project. Calculating the correct slope is essential to ensure proper drainage of rainwater and avoid future problems. Use the methods mentioned in this article to calculate the slope of your roof and consult a specialized professional to get specific guidelines for your case.
