Operated roof: general characteristics

Principles for the construction of the roof in operation

Roof with additional operation has different functions. Its quality and long-term use depend on the initial correctness of the arrangement of the roofing pie. It is important to clearly define the quality of the roof and its exact ability to withstand the load. These calculations are best entrusted to the designer. It will provide data on the amount of weight possible for placement on the roof surface, the optimal material variant and the roofing method with the help of a self or computer calculation.

Before developers should face the current and main question, what weight is able to withstand the roof pie flat roof? Answer: 25 tons per square meter. Of course, roofing materials are of super strength.
During operation, the roof is constantly exposed to ultraviolet rays. The used building materials are used with the characteristic "UV-stable".
The load on the surface of a flat roof comes from the pressure of the elements placed on it: the car, the movement, the movement of the person.

Classification of roofs in use

Roof pie consists of several layers. Its main function is to protect the room from getting wet. It consists of a roof heater and its waterproofing layer. Waterproof film is laid on the layer of the insulation, not allowing excess moisture to penetrate the material( mineral wool) and protecting it from evaporation, dampness and mold formation. This laying prolongs the service life of the roof and has the name of inversion( aligned in reverse order).

It is important to note: a quality roof will be obtained with the correct and most accurate calculation of the load on the roof. It is necessary to know the functional features of the roof. When constructing a parking lot( has the maximum load), expensive materials of impeccable quality are chosen. With a responsible approach of developers, the roof will not require repair for several decades.

There is a traditional type of pie roof. It includes in its structure:

• FEM;
• Separator and filter layers;
• Drain profile-film;
• Waterproof carpet;
• Insulation layer;
• Steam insulation;
• Cement-sand interlayers;
• The layer creating the slope;
• Overlapping plates.

The so-called "roof pie" forms the centers performing the tasks:

1. Formation of the gradient. Its parameters can have a value of up to 3 percent. He takes care of the water flow. If its design is incorrect, atmospheric precipitation will form accumulations and gradually destroy the building materials of the roof. To create a corner, use:
   • concrete;
   • slag;
   • expanded clay and leveling screed.
2. Waterproofing unit. Its task is to protect against leaks. Material of protection against moisture - film and hermetic adhesives( often used isospane).Term of application - up to half a century. Properties:
   • is resistant to loads;
   • is resistant to stretch marks.
3. Insulation layer. Thermal insulation is used. The goal is to keep the heat inside the premises and not to miss the heat in the summer. The layer of insulation should not allow moisture to pass through. In the event of a leak, condensation appears on the ceiling of the rooms, leading to imminent repair work.
4. Drainage layer. Its function is drainage. The drainage layer looks like a core and a kind of filter. Its structure is made of geotextiles, expanded clay and profiled film.

Advantages and disadvantages of different types of roofs in use

Positive qualities of the roof inversion system:

1. The heat insulation layer is able to distribute heat evenly and help protect the waterproofing layer from fluctuating air temperature.
2. Application of the mineral wool EPAS for thermal insulation is not very expensive.

   

3. The insulation of the roof can be removed from the waterproofing

Negative features:

1. Lack of possibility to use cotton wool for thermal insulation
2. layer Drainage occurs through a special funnel having a complex structure. This contributes to costly purchases of
3. . The EPPS can not use loads on individual sections of the
4. . The EEPP has a flammable surface. It should be protected with an additional layer of primer, concrete

Traditional roofed roof, its pluses:

1. It can be used for any type of insulation
2. Use of non-combustible thermal insulation materials

Cons:

1. Short-term use of waterproofing film
2. Roofing pie weighs heavily due to the mass of mineral wool

Types of exploitedroofs by appointment

On the main tasks of the roof are divided into:

• Terraces. They have different finishes - artificial or natural. They are used in the role of sports courts, recreation areas. The top cover is laid on additional: paving slabs are placed on the tier of sand-cement embankment. The drainage of such a roof is represented by a container or funnel.
  
• Flat roof. It is a green variant with plantations( lawns, flower beds).It is necessary to correctly organize the root system of plants and choose the appropriate soil layer for them. The drain is represented by a funnel.
• Parking roofs. Their goal - the placement of car parking. Such roofs have a high load on the roof surface. High-strength materials are used for them.
• Operated roof with pedestrian stripes. They are combined zones: recreation, car parking.
