Calculating the height of a gable roof
To correctly calculate the height of a gable roof, it is necessary to determine the slope angle. This indicator can be found in the regulatory documents called "Code of rules SP20.13330.2011", regulating this type of work. It is based on SNiP 2.01.07-85* "Loads and impacts". The document describes the formula for calculating the snow load for a gable roof and the wind impact formula. Depending on the region and its weather conditions, the permissible roof slope angle varies. In the central regions of Russia, this indicator ranges from 30 to 45 degrees.

Having determined the slope of the slopes, you can calculate the height of the ridge. Here you will have to remember your school geometry course. If you imagine the roof as a triangle, the required height of the ridge will be the unknown leg "a", which will divide its area into two right triangles. The formula for calculating the leg looks like this: a = b * tg α. We will find the second leg "b" if we divide the width of the house in half. Designing a gable roof is usually done along the long side of the building. Knowing the degree of inclination, we will use the table to determine the tangent of the angle.

By substituting all the necessary data into the formula, we can calculate the desired value.

Let's solve the problem: what will be the height of a gable roof under the following conditions:

Given: house 10x12, roof pitch 40 degrees.

The width of the house, equal to 10 meters, is divided in half. Therefore, the leg b=5. The tangent of 40 degrees is 0.84.

Thus, the optimal height of the ridge will be: a=5*0.84=4.2 meters.

You see how simple it is, you didn’t even need a calculator.

When is a house considered one-story?
It may happen that the calculated height of the ridge is not sufficient for optimal use of the attic floor. In this case, you can slightly raise the point of junction of the roof to the side wall of the second floor above the floor level. In order for the house to remain one-story, and you pay less taxes for the area of ​​the second floor, the junction point should be less than 1.5 meters.

The problem of how to calculate the height of a gable roof is faced by saudi arabia mobile database future homeowners. It is not difficult at all to determine the height of the roof if you use the method given in my article. I hope I helped you figure it out. In the next article, I will talk about the heat pump.
