The main types of roofs and their advantages

Roof shapes for the house.

Before making a roof, you need to decide what materials will be used for roofing, thermal insulation, waterproofing, and so on. It is necessary to draw up an exact plan on which all dimensions will be applied, it is desirable that everything be in digital values. It is not necessary to know the area, it is necessary in order to accurately calculate the amount of material for construction and not overpay. After collecting all the information, the developer can begin to install a roof for the house.

Any specialist in this field should know what types of them exist. They are single-slope, double-slope, three-slope, hip, half-hip, gable and multi-slope. The easiest way to calculate those of them that do not have kinks. But increasingly, builders are making multi-pitched and hip roofs, so the material has to be carefully calculated. If in simple roofs all surfaces are presented in the form of regular triangles or trapezoids, then in the latter case they can have a wide variety of geometric shapes.

Norms of living space in Moscow, the Moscow region and St. Petersburg

Each region fixes housing standards with its own regulations. For example, Moscow has Law No. 29 “On Ensuring the Right of Residents of the City of Moscow to Housing”, which establishes:

accounting rate in the amount of 10 sq.m. per person for individual apartments and 15 sq.m. for apartments that are provided by a court decision to different families.
the norm of providing housing area per person equal to 18 square meters. meters.

Based on the norm of housing, apartments are provided with an area of \u200b\u200bnot more than:

44 sq.m. - one-room apartment, for families of two people who are married;
54 sq.m. - two-room apartment, two tenants who are not spouses;
62 sq.m. — two-room apartment for a family of three, two of whom are married;
74 sq.m. - three-room apartment, for three unmarried tenants.

Each family member of four or more - 18 sq.m. per person. The resulting area of the apartment cannot exceed 9 sq.m.

Families of Muscovites, where there are disabled people with disorders of the musculoskeletal system, are provided with housing in buildings built in compliance with the standards of the rehabilitation program.

Law No. 407-65 "On the procedure for keeping records of citizens as those in need of residential premises ...", which is in force on the territory of St. Petersburg in relation to housing standards, prescribes them in less detail.

Grant rate:

a single person is supposed to - 33 sq.m.;
for families with two or more people - 18 sq.m.

Accounting norm for housing area in St. Petersburg:

residents of individual apartments - 9 sq. m. of total area;
residents of communal apartments - 15 sq.m of total area.

The above norms are used when providing individual apartments and rooms in communal apartments.

If housing is located in a hostel, then the standard is at least 6 sq.m. per person, with a ceiling height of at least 2.1 meters.

How to calculate square meters

From time to time, we face the problem of how to calculate square meters: when calculating utility bills or during repairs, when you need to calculate how many rolls of wallpaper you need to paste over the walls, or how many cans of paint.

In fact, all these data are indicated in the technical passport, which gives a clear layout of the apartment, indicates the number of square meters of each room and the total area of the apartment.

How to calculate square meters of walls

If you don’t have a passport, but you still need to find out, for example, how to calculate the square meters of walls, then it’s actually not so difficult to do this. To do this, you will need school knowledge of geometry. Namely, the formula for the area of a rectangle is S= a*b. That is, you need to multiply the height of your walls by the width. To do this, do the following:

Measure the width of the wall. This is best done along the floor or ceiling lines, as these lines are the most perpendicular.
Change wall height. This is the distance from floor to ceiling. As a rule, in “Khrushchev” it is 2.5 m, in “Brezhnevka” - 3 m, in “Stalinka” - 3.5 or 4 m. But it is best to measure it yourself, so as not to miscalculate.
Find out the area. The resulting values \u200b\u200bshould be multiplied among themselves - and you have the sum of square meters of one wall.
The amount of areas. Since there is not one wall in the room, but four, the same operations must be done with the rest of the walls, and then add up the resulting 4 areas. As a result, you will have square meters of the walls of the entire room.
Subtract excess. Each room has at least one entrance. In modern apartments, redevelopment with different arched and other openings is very fashionable. Naturally, if you need to calculate the number of wallpaper rolls, then you do not need this distance. Therefore, measure the height and width of the opening, multiply them and subtract the resulting number from the total number of meters of walls.

As you can see, there is nothing complicated about this. If you are interested in how to calculate the square meters of a room, then this is even easier.

How to calculate the square meters of a room

The basic formula is still the same. Only now we need the length and width of the floor.

We measure the width. If you have furniture along the wall, do not immediately drag it somewhere. You can easily measure the width along the wall or ceiling - the room consists of rectangles, and its parallel sides are equal.
We measure the length. We measure the adjacent wall / floor / ceiling.
We find the area. We multiply the received numbers - and that's it.

If you need to calculate the square meters of the entire apartment, the principle is the same: we count each room, corridors and closets, and then add everything together.

It's that simple.

Main stages of work

The calculation of the roof area should always start with :

getting acquainted with the future project of the roof of the house and remembering the most key parameters: ridge length, slope angle, height, width and length;
determining the type of roofing material to be used.

One of the most important characteristics is a special calculation coefficient, which is present in absolutely all formulas. Its value depends on the angle of the roof slope and is determined by the following relationships :

with a slope of 9 ° slopes, the coefficient will be 1.01;
for 14° - 1.03;
for 18° - 1.05;
at 23° - 1.08;
at 27° - 1.12;
for 34° - 1.2.

The specified range of roof slope angles is the most popular options used in construction in our latitudes. It is possible to determine the parameters of a structure with a complex geometric shape by breaking it down into separate small figures, which can be easily calculated by summing up the obtained values at the end. Experts recommend adding about 10% to the result, which is the standard margin in construction.

Calculating the area of a rectangular room

A room that does not have any, even small, ledges and niches, or, simply put, is rectangular - the easiest option for taking measurements and calculating area values. Here it is enough to recall the simplest formula from a mathematics course - how the area of \u200b\u200bsuch a figure as a rectangle is calculated. To do this, you need to measure only the width (A) and the length of the room (B). Thus, we get that S (area) will be equal to the value that will be obtained by multiplying the two indicators A and B.

All measurements are given in meters. Centimeters are indicated after the decimal point. For example, the length of the wall turned out to be 376 cm, then it turns out (in 1 m - 100 cm) that the length of this wall will be 3 m 76 cm.

If the room has a fireplace, then you need to calculate its area and subtract from the resulting figure. After all, flooring will not be laid under the fireplace. Of course, if we are not talking about the dismantling of this structure.

In order not to suffer with manual calculations on paper and not to master computer programs, you can use the help of online calculators. This opportunity is provided by a lot of Internet resources. In a special window, it is enough to enter all the data, and after clicking the "calculate" button in a new field or on a new page, the final calculated data will open. Usually, all indicators are entered in meters, but other units of measurement can be specified if desired.

Advantages of online calculators:

no need to count manually;
you can easily get the area of \u200b\u200bany figure;
the speed of calculations and their accuracy are high.

The importance of roofing

Currently, all over the world, including Russia, such a branch of the national economy as construction is developing at a rapid pace. Since ancient times, this type of activity has been highly valued and in demand. And to this day, nothing has changed. Thousands of new houses are built every year, new ones are equipped and repaired. Owners of private houses, who decorate their property, are especially interested in construction. It can be small cottages, houses or large cottages. One of the important stages of construction is the roofing.

Building a house is never complete without a roof, so you should carefully approach the design of this part of the house, because. it is she who protects the house from precipitation and other natural influences.

The house, that is, its appearance, is largely determined by it. The roof can be covered with various materials: slate, metal tiles, metal sheets and so on. The work requires accurate calculations of the material and the necessary tools. Both specialists and the owner of the house can cover it, it all depends on the desire and skills. Plus, you can save good money. Let us consider in more detail how to calculate the area of this part of the house, because this is one of the main and most important preparatory stages in the course of work.

Preparation for calculations

Before you start calculating the quadrature of the roof, you need to find out exactly what shape it has.

If it is complex with uneven edges, it is always possible to divide it into several simple shapes and calculate their size (area).

What shape is the roof most often: rectangular, square, trapezoidal, triangular, parallelogram shape.

In addition, the more different shapes of slopes on the roof, the more difficult it is to calculate its area. But this fact should not stop.

The main advantage of any roof is that its area can be calculated by breaking it into simple shapes. Let's consider in more detail.

What are the roofs:

Flat or flat. They have a minimum slope angle, no more than two or three percent of the horizon.
pitched. They have an inclination angle of ten percent or more (relative to the horizontal plane or horizon level).

The latter, in turn, are divided into single-slope and multi-slope (one-, two-, and so on). A fairly common option for building a roof is the so-called gable, that is, a gable ordinary roof.

It has two absolutely identical sides, having the shape of rectangles, in which one side is a long edge running parallel to a long wall, and the other is a segment located at an angle.

To calculate its area, you need to multiply the length by the width, and also by two, since there are two slopes. When carrying out calculations with more complex forms, you will have to divide them into simple ones, calculate each of them and add (sum).

To make a correct and accurate calculation. you must first draw a diagram of the location of the elements of the roof with the drawing on this plan of dimensions expressed in one system of units. If a plan has been preserved after construction, you can consult it or use it for calculations.

To determine how much roofing material is needed for hydro-, noise-, vapor barrier of a house, it is necessary to calculate the roof area.For simple single-pitched or double-pitched roofs, it is enough to know only two measurements, and for complex shapes, you will have to divide the plane into several simple geometric shapes.

Important points to consider before making calculations

How to calculate the square of the roof of the house? To begin with, it is worth studying the memo for accurate calculations:

It is necessary to divide a non-rectangular roof into parts of a complex configuration to simplify further calculations.

These parts can be triangles, squares, rectangles, and so on.
To calculate the amount of building material that will cover the roof, it is important to take into account the quality of the coating.
The area of a pitched roof for the purchase of soft, galvanized, slate material can be calculated by the formula. S = (Width of eaves x 2 + Length of house) x (Width of eaves x 2 + Width of house) / cos (Angle of inclination).

If the width of one slope (the segment from the corner of the roof to the ridge) and its length are known for a gable roof, the simplest formula is used to determine the area of \u200b\u200bthe rectangle. Namely: S = A x B. Here A is the length, B is the width. The resulting value is multiplied by two, since there are exactly two slopes.

Calculation scheme for a gable roof

When dividing a roof of a complex shape into several simpler figures and further carrying out calculations, the formula for the area of \u200b\u200ba right-angled triangle can be useful: S \u003d 1/2 x A x B. Here the letters A and B indicate the legs, that is, those sides of this geometric figure that are adjacent to right corner of the triangle.

To calculate the area of an isosceles trapezoid (if one of the roof slopes has a regular trapezoidal shape with sides of the same length), in addition to the width of the slope, you need to know the length of the base of the trapezoid (usually this is the length of the house or a little more) and its height h (perpendicularly drawn segment, connecting the top of the ridge and the base of the trapezoid slope): S = (a + b) / 2 x h.

When dividing the entire roof surface into different geometric shapes, it is necessary to arm yourself not only with a tape measure, but also with formulas for calculating the area of a triangle, rectangle, trapezoid and parallelogram.

How to calculate the square of the walls

Determining the area of walls is often required when purchasing finishing materials - wallpaper, plaster, etc. This calculation requires additional measurements. To the already existing width and length of the room you will need:

ceiling height;
height and width of doorways;
height and width of window openings.

All measurements are in meters, since the square of the walls is also usually measured in square meters.

Since the walls are rectangular, the area is calculated as for a rectangle: we multiply the length by the width. In the same way, we calculate the dimensions of windows and doorways, subtract their dimensions. For example, let's calculate the area of the walls shown in the diagram above.

Wall with a door:
- 2.5 m * 5.6 m = 14 square meters m. - the total area of \u200b\u200bthe long wall
- how much does a doorway take: 2.1 m * 0.9 m = 1.89 sq.m.
- wall excluding doorway - 14 sq.m - 1.89 sq.m. m = 12.11 sq. m
Wall with a window:
1. square of small walls: 2.5 m * 3.2 m = 8 sq.m.
2. how much does a window take up: 1.3 m * 1.42 m = 1.846 sq. m, rounding up, we get 1.75 sq.m.
3. wall without a window opening: 8 sq. m - 1.75 sq.m = 6.25 sq.m.

Finding the total area of the walls is not difficult. We add up all four numbers: 14 sq.m + 12.11 sq.m. + 8 sq.m. + 6.25 sq.m. = 40.36 sq. m.

We count the number of tiles

Knowing the area of the room, it will not be difficult to calculate the amount of flooring. Let's figure out how to figure out how many tiles you need for a particular room. To do this, you need to find out what is the area of \u200b\u200bone element of the tiled coating. Knowing these data, it is easy to make the necessary calculations. For instance:

room area - 15 m2;
the size of one tile unit is 0.20x0.30 m.

Thus, the area of one tile will be 0.2x0.3 \u003d 0.06 m2. Further, the total area of the room is divided by the area of one tile and we get: 15 / 0.06 \u003d 250 units.That is how many tiles it will take to close the entire subfloor in this room. In exactly the same way, the amount of laminate or parquet board, as well as other materials, is calculated.

To calculate the floor area in a room, and then the material consumption, it is enough to know elementary mathematical formulas and be able to use a calculator. Having the latter at hand (and now every phone has a calculator), you can make calculations quickly. The main thing is to be careful when taking measurements.

As can be seen from the above data, the minimum indicators of housing provision standards are almost the same in the regions of Russia. Please note that this is the lowest limit of indicators, which may increase depending on the circumstances. But less than its norm cannot be applied.

How to calculate the roof area of a house

At the beginning of construction, the question always arises, how to quickly and correctly calculate the roof area? This operation seems simple only at first glance. In practice, it turns out that the calculation can be quite difficult even for experienced craftsmen. Since the total amount of money spent on the construction of the roof directly depends on its correctness. Given the high cost of building materials and the cost of installation work, you can try to reduce the cost of the entire project. Let's try to figure out what is needed to perform the correct quadrature calculation.

How to calculate the area of a room

For this, only minimal knowledge of school mathematics is required. Everyone remembers that the area of a rectangle is equal to its length multiplied by the width using a calculator. This rule should be used when measuring floors and walls in rectangular or square rooms, such as a bathroom. You can write the formula:

S \u003d A * B, where S is the quadrature of the room we are looking for, and A and B are the length and width.

But even in such a simple formula, you need to double-check yourself. Few houses have walls and floors that are perfectly even. In order not to make a mistake when buying materials, you need to measure the room not only in the corners, but also check the height or width in the middle of the room. If these values differ from previous measurements upwards, then it is necessary to use them when calculating in order to take materials with a small margin. Let it be better to stay a little than end at the very last moment, when the repair is already coming to an end.

Measuring the area of walls with windows and doors

The previous measurement method is suitable for ceilings, floors, as well as walls in which there are no openings. If they are, then, as a rule, they have the same rectangular or square shape.

It is necessary to measure the area occupied by windows and doors. To do this, in the same way we measure and record their length and width and calculate their quadrature. As a result, from the total quadrature of the wall, we subtract the obtained values \u200b\u200bfor the openings on the calculator and get the desired figure.

For example, the area of the walls in a room is 36 square meters. After measuring the window, they found out that its dimensions are 4 square meters. This means that the materials for finishing the room must be bought with the expectation of 32 square meters.

Measurement of a room with niches

In the event that the room has an irregular shape, it has ledges, niches or pieces of furniture that cannot be moved, then the principle used to calculate the area is similar to calculating the area of a room with windows. Different niches can affect the area of \u200b\u200bwalls and floors. For a correct calculation, you need to separately measure the area of \u200b\u200beach such element and subtract it from the total quadrature of the surface we need: in the same way, we subtract the area of \u200b\u200bsmall rectangles from the large one on the calculator.

Measuring the area of an irregularly shaped room

If the room is not rectangular and has various protrusions or a polyhedron shape, then it is better to calculate its quadrature through the perimeter. For example, such protrusions include a bath or shower in the bathroom.

The perimeter of the room is easy to measure. This is the sum of the lengths of all its sides. To do this, just walk with a tape measure along all the walls and summarize the resulting segments.

Now, knowing the perimeter of the room, we need to schematically depict it on paper. You need to draw a sketch that is as similar as possible to the room and divide it into regular shapes, the quadrature of which is easy to calculate: triangles, squares, rectangles and sectors. We sign each measurement on the sketch and calculate the areas of the resulting figures:

To find the area of a triangle, multiply the lengths of its legs and divide by 2.
For a segment: we need to take its radius R and multiply it by half the arc length L.
For a circle, you need to square its radius and multiply by pi. It is equal to approximately 3.14 and has a constant value.

For ease of calculating the area of irregularly shaped rooms on the Internet, you can now find online calculators. It is convenient to use them: you need to choose the layout of the room and enter your measurements, and the program will automatically calculate the dimensions of the room. With their help, you can quickly find out the square footage of the bathroom, kitchen, non-standard living quarters.

Step by step calculation of the area of the room

Step 1. First of all, you need to prepare all the measuring tools, as well as a piece of paper and a pen. On paper, you can pre-draw a diagram of the room, trying to preserve the geometry as much as possible and display all the niches and details of the room. Roulette is used as long as possible.

Step 2 Measure the length of the room. If it is so large that there is not enough tape measure, then measurements are taken in stages. To begin with, a measurement is made for the maximum length of the tape measure, a mark is made at the place of its end, from which it is then again measured to the end of the room.

Step 3. The width of the room is measured (along the wall with a shorter length). The tape measure is located at right angles to the previously measured wall of the room (length). The received data is recorded.

Step 4. The obtained indicators are multiplied among themselves. For these purposes, it is recommended to use a calculator. If necessary, the area value is rounded up.

Step 5. If you need to measure the area of a complex geometric room, then first the complex figure is divided into several simple ones - squares, triangles, rectangles. The object is depicted on a piece of paper schematically, schematically divided.

Step 6. Each figure is measured separately. For example, rectangles, triangles.

Step 7. The area of each figure is calculated.Further, all the obtained values \u200b\u200bare summed up and the total exact floor area of \u200b\u200bthe room is obtained.

What tools are used to calculate areas

Various computer programs can be used to calculate the area of a room, and various mathematical formulas for calculations are also used. But the dimensions of the sides of the geometric figure, which corresponds to the room, will have to be removed in any case.

Table. Tools for taking measurements of the room.

Necessary for recording received readings. If the readings are not recorded, then you can quickly get confused. Also, paper and writing utensils will be useful for drawing up a floor plan.

With its help, all dimensions are determined directly. The larger the room, the longer the tape measure will have to be purchased. You should not use a soft fabric centimeter tape, which cutters use - it is quite short and soft, so it will be inconvenient to take measurements and errors can be made.

Required for all mathematical operations. It is convenient in that it will reduce the risk of errors.

A handy device that allows you to quickly and accurately take measurements of any room.

May be needed to measure angles in a room. It is worth remembering that even seemingly right angles are not always so. And sometimes you need to know the exact size of the angle.

Manual calculation on a piece of paper is convenient in that all parameters can be immediately measured on the spot and make the necessary adjustments. But it’s quite easy to make a mistake with the manual method of calculations, so it’s better to recalculate all the indicators once again.

To automatically calculate the area of a room, it is convenient to use various graphic editors. It can be AutoCAD, ArchiCAD or SketchUP. They create a figure according to the shape of the room, the dimensions of all its sides are indicated when creating the layout. The area of the room will be given by the program automatically and with high accuracy (up to centimeters and millimeters). Everything will depend on the accuracy of the measurements taken. Especially the use of these programs is recommended if it is necessary to calculate the area of a room that is complex in its geometry. The disadvantage of this method is the need for at least a superficial study of programs, as well as the use of computer technology.

Accounting norm and norm for the provision of living space

The concepts of these terms are given in Article 50 of the RF LC.

The provision norm is considered to be the smallest number of residential meters to calculate the total area of \u200b\u200bthe premises that will be provided to the family under a social lease agreement.

Most regions take 18 square meters as a basis. m. of area, they are used as the norm of provision. This size is minimal and can be increased in some cases:

a room or an apartment with one room is provided;
housing is transferred to a person with chronic severe illnesses.

The standards are also being increased for employees of internal affairs bodies with a rank not lower than a colonel, as well as for persons with an academic degree. However, the increased rate cannot result in more than two established values.

The accounting norm is the minimum living space that is accepted to recognize a family in need of improved housing conditions. Citizens whose premises will be less than this value have the right to take the appropriate queue. This applies only to those citizens or families who are recognized as low-income.

It should be clarified that all persons who are registered in the premises permanently and temporarily participate in the calculation of need. But it is impossible to register an unlimited number of people in one living space for the purpose of recognizing a family in need of improved living conditions. This will not be allowed to do by authorized bodies. Most often, the lack of square meters occurs with the appearance of children in the family, who, according to the law, must be registered with their mother.

The authorities of each region independently determine the accounting standard for living space, but it cannot be lower than the provision standards.

Housing standards are applicable when providing housing for a number of categories of citizens who are unprotected and in need of state assistance.

1. Orphans and those left without parental care. This category of housing is supposed to:

at the end of the stay in specialized institutions, as well as at the end of the period of being under guardianship or in foster families;
after completing military service;
after the expiration of the term of stay in places of deprivation of liberty.

The size of the transferred housing under a social lease agreement is subject to regional standards, but may be higher than them. The contract is concluded for five years, and then transferred to personal use. Orphans must be allocated separate housing, representing a well-appointed apartment or house.

2. Settlers from housing, recognized as dilapidated and emergency. Most often, such residents are relocated to the municipal mobile fund, hostels. Here, the established norms must be observed. Although the new area may be smaller than the one from which the resettlement takes place. In the case of privatization of emergency housing, the same number of meters that was owned is offered instead.

3. Resettlement from houses to be demolished. The withdrawal of such apartments is subject to the following conditions:

new housing is provided at the conclusion of a social contract of employment;
the new premises must be well-maintained and in the same settlement;
the area of the new housing is commensurate with or larger than the old housing.

At the same time, if the premises from which the eviction takes place is less than the established norms, the family may apply for an improvement in living conditions.

4. Servicemen. This category of citizens has the right to receive housing from the state. Here, established standards apply, depending on the composition of the family. Each family member should have 18 square meters. m. of living space, and for a single soldier, the room should be 18-25 squares. For this category, the standards are set by regional authorities.

Conclusion, conclusions, recommendations

It can be concluded that covering the roof with one material or another is a rather simple matter. At the same time, it is imperative to select the necessary material, take measurements, following all the instructions, calculate the required amount of roofing and compare it with previous measurements. The basic principle underlying the calculations is the breakdown of large and complex surfaces into smaller geometric structures, for example, regular triangles, squares, trapezoids. This is optional, but it will make things easier and save you a lot of time. If your abilities in mathematics are weak, then it is best to seek help from specialists who know a lot about this matter. They will do everything quickly and efficiently.

There is a formula by which calculations are carried out. It contains data such as the length and width of the house, the length of the rafter leg and the dimensions of the slopes.

For this part of the house, it is important to measure the size of the overhangs and take into account the percentage of expected waste, most often it is 10-15%, and this is a lot. The amount of work is largely determined by the type of house.

Houses can be simple with a shed roof or with intricate outlines, respectively, and the roof surface will be uneven. Laying technique is also of great importance. It's one thing if the pros work, and the other is inexperienced owners who do not know all the subtleties. Therefore, if you plan to cover the roof of your house with your own hands, then this material will help you do everything correctly and consistently. If there are difficulties, then it is better to call a team of specialists.

Final Conclusions

The area when using other materials can fundamentally differ.For this reason, for each particular case, an individual approach, careful analysis and competent calculation are required. The most difficult situation arises when it is necessary to calculate the quadrature of roofs of complex shape. To get a reliable result, you should follow a few simple rules. :

the first step is to divide the plane of the roof of the house into several geometric shapes of a simple shape. Next, using simple mathematical formulas, you should calculate the area of \u200b\u200beach simple figure;
when calculating gable roofs, it is necessary to multiply the resulting quadrature value by the cosine of the angle of inclination of the roof;
the length of the slopes should be measured from the extreme point of the eaves to the ridge itself;
to calculate the absolute area of the roof, it is necessary to calculate the area of all available elements of the roof structure, and then sum them up;
each individual slope can be divided into simple shapes of various shapes, by counting the area of \u200b\u200bwhich, you can calculate the quadrature of the slope.

You should be aware that when calculating the area, it is important not to forget to take into account ventilation ducts, skylights, chimneys, parapets, hatches and other elements. In case of violation of this rule, there is a high probability of a shortage of building materials during the arrangement of the roof

Correct and competent calculation of the area will provide all the conditions for the optimal use of funds associated with the purchase and cutting of material during the construction of the roof of the house.
