How to calculate the area of ​​the roof: important nuances

At the preparatory stage of the calculations necessary to carry out a number of activities:

• originally recommended to prepare a plan of the building roof in terms of its inclination
• second step is measurement of construction tape.It is advised to resort to certain programs on the calculation that allows to obtain the most accurate data
• Based on the results of measurements should determine the type of roofing

often used for a long time tested formula for the calculation of the size of the roof plane.Considering the most common form of triangular rays, should apply the formula of the science of geometry.

originally measured the angle of the ramp.He is a major in subsequent computational processes.Consider the roof slope coefficient:

1. angle of 9 degrees is 1,01
2. coefficient of 14 degrees is 1, 03
3. At 18 degrees - 1,05
4. 23 degrees angle has a coefficient of 1,08
5. angle of 27 degrees -1,12
6. maximum angle of 34 degrees - 1.2 coefficient

roof, which has a complex structure - hipped, hipped, trehskatnaya and others - is subjected to the calculation of the phase space.It is divided into parts, the total area is considered separately, after all is added.Often the final result is added plus ten percent (taking into account the small errors).

How to calculate the area of ​​the roof: consider the different slopes of the roof

Since metering area roofing system and determining the required number of building material, you need to decide which kind of roof deals zamerschik.Consider each type of ramp separately.

Calculating area pent roof

Pent roof is one of the simplest designs.Its calculation does not require any professional knowledge.Shed option often has a standard coating.The classical form of such a roof - rectangular.Based on the knowledge gained in school, area of ​​a rectangle - the length and the width multiplied by each other.It is enough to know the parameters of length and width of the roof.

roof area calculation of the two ramps

Gable roof is triangular in shape.The calculation of its area produced by the geometric formula.A roof slope naimenuem "C", 50 per cent of its width should be divided by cos 30 degrees (cosine 30).Result - 0,866.

Calculating the size of the planes gable roof has its own calculation of the subtleties.It is necessary to take into account the peculiarities of a gable roof, consider them to approximate example:

• One ramp has a length of 5 meters
• Its ridge element 8.5 meters

Calculated: 5 * 8.5 * 2 = 85 square meters (multiplied by two by two the number of rays).We get the value of the roof.

Some material requires its own calculations.Just calculate the area of ​​the roof slopes are not enough.Given the high prevalence of roofing metal tile, consider his calculations.

metalocherepitsy One layer is often the default settings:

1. single wavelength is sold with the parameters width 1.1 m, length - 0.35 m
2. three-wave - width 1.1 m, length 0.5 m

Knowing the type selectedmetal, you need the length of the ridge element divided by the width of the seam.The result is rounded towards higher value.This will be the amount of sheets to cover the gable roof.

Note: the original is found clear parameters in sheet metal manufacturing companies.Calculation of building materials other types of roofing may vary.

Roof area with complex designs

roof having more than two rays, called the complex in its calculations.Before the start of their worth to get acquainted with important tips:

1. Initially advised to divide the entire surface of the roof of the building into separate components.This will simplify the calculation of the total area.Calculate the area of ​​individual squares, rectangles and triangles much easier
2. calculation result gable roof all of the individual components is recommended multiplied by the cosine of the angle
3. roof Slope is measured from the tip of the eaves and to the skating element
4. received the sum of each individual element are added to each other,and get the final figure
5. Even a simple ramp may have extra add-ons.Add-ins is measured separately
6. When calculating the cost to take into account the details of ventilation, chimney channels, window frames, parapet installation, hatches.These parameters take into account when ordering roofing

formula for calculating the area of ​​the roof

Additionally, it is worth mentioning features of area calculation.You have to remember about:

• form the roof;
• parameters of additional elements;
• presence of overlap;
• method of roofing;
• type of roofing.

When roofing slate using the formula area: S = (2 XA + B) * (2 XA + C) * cos30.
components of the formula:
A - width of the overhang;
B - the length of the walls of the building;
C - width.
The angle take 30 degrees.When
roof metal tile expect further valleys, ridge board, cornice overhang.Material not buy a stock on laps.Its area of ​​formula: S = (B * h) / 2.
components of the formula:
S - area of ​​the entire surface;
B - length of the base of the triangular roof;
H - height.

Important note: The maximum area of ​​a precise calculation can give the wrong number of indicators required a roofing material.It is important to take into account the angle of the roof construction look.It is necessary to take into account all the nuances of the roofing system and calculate the area of ​​a pitched roof as accurately as possible.
