All those who have had to build are well aware of the seriousness of the choice of blood material. Any attempt to save on this part of the building is most likely to be compromised, as stated by the " lot " , so the search for a reasonable compromise is well found.

The selection of a type of reference material and ultimately determines the calculation of the cost of work, that is, how much the roof should be built.

In addition, the type of building that is built has a significant impact on the cost of the roof. For temporary construction, for example, there would be a perfectly simple cover not designed for long periods of service. In the case of capital housing, the life of the roof should be compared to the life of the entire building.

When selecting suitable material for the roof, it should also be borne in mind that its full cost would include all additional costs, namely:

• Cost of maintenance materials;
• Maintenance costs;
• transport costs, etc.

Example calculation of roof costs

Example of roof costs

Clearly, the roof of the turtle will cost you much more than the coating of other materials because it will require a more powerful and, as a consequence, a more expensive system. We're suggesting that you compare the cost of a roof from different materials in the example of an extra-urban house built on an individual model project. The basis of the calculation is as follows:

Cover of roof

Basic roof parameters for our calculation:

• The roof is 200 square metres.
• It's 20 meters long.
• The Andes and Frontons are 16 and 40 metres respectively.
• Carniza length is 20 meters.

The use of ad hoc tables (see annex) which provide data on the cost of 1 square metre of the finished roof, taking into account all additional costs, will allow you to make an approximate estimate of the future budget.

For our example, the cost of 1 square metres of blood is approximately 2,600 to 3,000 roubles. And the most expensive thing is a roof from a soft turtle, and the cheapest. - from polyester metallurpies.

Costs for different blood material

Values for different materials

Previous calculations clearly indicate the following: An integrated assessment of the cost of building the roof of the house shows that the increase in the value of the fully filled roof (depending on the material used) occurs in the following sequence:

1. Polyster metallurpine.
2. A soft turtle.
3. Polyurethane Metal.
4. Cement and cement.
