The minimum angle of inclination of the roof of the metal: what are the advantages of metal

How long the house will last and the roof will last directly depends on which roofing material will be used. Naturally, it is also important how the building will look externally, as well as how clean the roof will be. In our time, the most popular material has become meteor tile. It has high rates of resistance to the effects of the environment, intensive loads, and also has a good bearing capacity. Naturally, in addition, for durable service, you need to choose the minimum angle of inclination of the roof of the metal. Which optimal parameters to use for this characteristic is described in the article.

What are the advantages of metal tile

This material It has several advantages:

1. Metal light weight . From five to seven kilograms falls on one square meter. With its help cover the roof, which has a complex structure. Thanks to its lightness, it is unnecessary to reinforce rafters. This roof does not load the walls and foundation.

2. Due to the simplicity of installation of the roofing material and the absence of the need for special tools, the cost of work on installation is relatively low.

3. This roofing material has a wide color palette , so you can choose any of them to fit the overall tone of the building.

4. The tiles are made from thin sheets of steel, the thickness of which is from 0.4 to 0.7 millimeter. Thanks to the profile, it is able to withstand heavy loads .

5. The sheet of roofing material is protected against corrosion by galvanized metal and a protective polymer layer that is applied to the surface.

The main advantages of the material are durability, low cost and aesthetic appearance.

What is a slope

The slope of the roof is the angle that forms between the roofing material and the overlap.

In documents, it is indicated in percent or degrees. Calculate its mathematical division of the distance from the highest point and the intersection of the rafters, which is called the ridge into one second the entire width of the building. From the roof slope depends:

• how material the building will be covered;

• construction of the roof and its main parts;

• as far as the roof can resist to atmospheric phenomena;

• cost of work masters of roofers;

• weight of all layers used.

Note! If you change the slope of the roof of metal from 22 to 45 degrees, then the slope will increase by 20%. And this will significantly affect the cost of roofing materials, as well as the weight of the whole structure. In this case, the slope must be determined in the process of designing the entire building in order to have an idea of ​​the load on the foundation.

What determines the slope of the roof

For those people who are completely unaware of construction, it is very difficult to determine what the minimum slope of the roof should be. Here it is necessary to take into account natural factors that constantly have an impact on the roof. These include:

• The snow layer that falls in winter. If the inclination angle is greater, then the snow will slide off.

On our site you can find contacts of construction companies which offer services to design and repair a roof . Directly to communicate with representatives, you can visit the exhibition of houses "Low-rise Country".
• Ability resistance to wind . In such regions where the winds are constantly blowing, it is necessary to make the slope minimal so that the wind gusts glide over the roof and does not create the effect of the sail.

Since this material is very light for covering the building, the crate is allowed to be rare, but when installing rafters, you must strictly adhere to the distance and angle under which they will be installed.

How many degrees should have a minimum angle

The minimum roof slope of a metal tile is 10 degrees. Allowed slope, which ranges from 10 to 90 degrees. Choosing the optimum angle of inclination, it is necessary to take into account that with a small degree the space between the roof and the overlap cannot be used for any economic purposes.

If the largest angle of the roof for the metal tile is set, then it will be very difficult to go out onto the roof, in order to carry out technical work. Moreover, the greater the angle, the higher the ridge and, accordingly, the area to be covered increases.

Correctly calculating the angle of inclination of the roof for metal tiles, the calculator should take into account the following aspects:

1. Model of tile . It should be noted that the majority of manufacturers in the product description indicate the minimum slope of the roof of the metal.

2. Which type of roof is planned: single or dual.

3. How will snow be removed from the roof.

After carrying out all the calculations, and taking into account the above points, provided that the length of the surface of the slope is 6 meters, the minimum slope is set at 22 degrees. Naturally, this result is not specified in the technical documentation. It is calculated by experienced craftsmen in the process of observing the roofs already used.

Calculations

To determine more precisely what the minimum slope of a metal roof tile gable roof should be, you need to know two numbers:

• height from the top of the parapet to the ridge;

• width of the building.

To calculate, divide the distance from the parapet to the skate by half the wall and the result is the desired angle.

To determine the result in percentage, the resulting number must be multiplied by 100.

Important! For the result to be accurate, it is necessary to measure the distance to the ridge not from the overlap surface, since this is a gross error, namely from the upper part of the parapet.

Naturally, there are exceptions in construction, when the slope is only 10 degrees. But this is done in the case of special recommendations for construction. It should be borne in mind that with such a slope an increased load on the surface is created when snow falls. Thus, the crate is solid. In addition, it is necessary to lay a waterproofing carpet on it. The flow under the butt side of the roofing sheets enclose special pads.

Conclusion

It is best, when working with metal tiles, to know the instructions from the manufacturers and follow them all without question. In addition, we must remember that experience is no substitute for anything, therefore, all installation work is better to be trusted by professionals. Turning to a reliable construction company, you get the speed of work and a documented guarantee.
