Roof reconstruction: the subtleties of the roofing work

Any building has its own resource, and sooner or later requires major repairs. Tidying up the walls is not the last task. Much more important event will be the reconstruction of the roof, which sometimes may require the complete replacement of all parts with new ones. The very process of reconstruction involves the preservation of the appearance when changing components. So the roof after the repair should be significantly updated, without losing the old properties and characteristics.

The process of reconstruction is needed in various cases, it is the need to expand the attic, and the replacement of damaged elements, or simply redevelopment of the roof. If you have to work with the roof, you can be sure that the process will be large-scale and relatively long.If the building has become more frequent dribbling of the ceiling, or the level of humidity in residential premises has risen, this indicates that some kind of malfunction has started on the roof.

Reconstruction of the roof of a private house, is the front of work, which has a clear goal, and is intended to improve the level of comfort of the people living in it. For work, they usually dismantle the old coating, check the integrity of the beams and floors, and, if necessary, replace them with new parts. If you need to insulate the ceiling, you can strengthen the crate so that it can withstand it. Ventilation is also provided, which allows materials to breathe, which contributes to longer operation.

Any reconstruction involves the improvement of the structural or operational characteristics of the building, making it more robust and reliable. The priority direction in this industry is the creation of new structures, and not the strengthening and repair of old ones. Strengthen the crate should be in the event that the roof is expected to increase loads. If the weight of the new roof is much greater than before, then it is better to completely replace the crate.In this case, the calculation of the cross section and the step of the beam for a certain roofing material.

If the roof itself is replaced, then you should pay attention to the truss system. In this case, the pitch, cross-section of the rafters, racks and their dimensions, struts and diagonal legs are checked. In cases where there is a need to perform a new roof configuration, then new calculations and construction of a completely new construction are performed.

Thus, minor repairs to the roof can be done as needed, but as soon as its results cease to produce the expected result, more extensive work is needed. The same applies to the processes with the change of external indicators or weight increase on the roof, in each case there are specific features of the work that you need to know and use correctly.

If during the operation of the house there are obvious problems with the roof, you need to find out and carry out appropriate repair work, up to a complete reconstruction of the roof.

The most common problems with the roof are the following factors:

• errors in the design process;
• defects in the installation of the structure;
• improper operation.

If miscalculations were made during the design, this will cause the truss structure to deform. This violates the integrity of the roof. Errors can also be in the process of calculating insulation, when in winter the roof will freeze and become covered with ice, from which the roofing material will start to deform.

With improper installation, you can also get a lot of problems. If you do not comply with the technological requirements and deviate from the plan outlined by the draft, problems with operation cannot be avoided. If low-quality material was laid on the roof, then very soon it will make itself felt by leaks and loss of heat.

To know exactly what needs to be addressed, it is important to find a professional who can correctly determine the cause of the problems. This will be the start to create a plan for the repair of the roof and estimates for it.

To carry out work on the reconstruction of the roof, a number of goals are set:

• Work with under-roofing space, increase its dimensions, and decrease. These works involve the creation of a new roof design, the activation of the wall and partition.
• Using the attic in the new quality, for which there is a need to repair the roof.

• Adherence to standards of sanitary standards in the event that the attic is allocated for living space.
• Change the attic to the attic.
• Additional building next to the house in the form of a kitchen or garage, which receives part of the roof of the house.
• A complete set of windows in the attic, to increase the amount of light in the room.
• Creating doors and balconies right on the roof of the house.

There are a number of other reasons that may necessitate the reconstruction of the roof:

• deterioration of the roof structure ahead of time, due to improper operating conditions;

• the consequence of the poor quality of work performed by the builders of the house in relation to the construction of the roof;
• careless attitude to the roof, a long lack of repair, even if it is badly needed;
• lack of ventilation in the roof construction project and its overlap.

These are possible reasons for which you may need to reconstruct the roof with a change in its appearance.

To understand which way to repair the roof to choose, you need to understand what kind of problem had to face. You should not rush to remove the roofing material until all communications, water and sewage pipes have been checked, if everything is in order, then you should pay attention to the roof sealing, you need to check if there are any contaminants on the surface or partial roof chips.When flat roofs are not uncommon is the displacement of the roof, which leads to negative consequences.

If we talk about how to repair the roof, then there are:

1. Partial repairs, they are carried out if there is some damage in the roof.
2. In case of damage to the roof by more than 37%. In this case, a major overhaul is carried out, where all damaged places are completely replaced and new ones are installed in their place.
3. For minor local damage to the roof, you can carry out local repairs.
4. If one or several leaks were found, then patches of special material are superimposed on them.
5. If you detect small cracks, you can seal them with a construction tape or use sealant.

Alteration of the dacha at home will not take long, because in a wooden dwelling the roofing elements will quickly deteriorate. To replace the old roof, if it has decayed or began to leak, you can build a new one or make a partial repair. It is not capital houses that are often built at the dacha, which means that works on its improvement and permanent repairs will be permanent. In order to somehow change this, you need to redo the house into a partially residential one, for which it is screwed up with bricks and a new, reliable roof is being built.

If the house is built reliably, it is not necessary to make global changes., it will be enough to replace the damaged parts and adjust everything to a new one. In the country house are often organized various extensions, and in a small area they are built right next to the house. For convenience and speed of construction, a new roof is not built, but the existing one is lengthened. For a wooden house, it is important to choose the right materials for both the roof and for insulation, in order to minimize the risk of fire hazardous situations.

The reconstruction process is essentially a voluminous work and requires different types of work, these are:

• change of old roofing sheets to new ones, if they are worn out or have mechanical damage;
• the process of reconstruction of the roof, and as part of it, work with rafters, and their replacement, if there is such a need;
• reconstruction, due to which the dimensions of the roof will change significantly;
• carrying out a complete reconstruction of both the roof and the attic.

The most logical variant of the course of work, if necessary, to cut off the roof or make some changes in its design, is thinking about what should be on top of the house and selecting a qualified team of workers who will put everything into life.

In this case, the workflow will look like this:

• experts will inspect the roof and together with the owner of the house will create an approximate drawing of the future construction;
• since the appearance of the roof and its dimensions will vary, you need to obtain the appropriate permission to work;
• when everything is decided, it is necessary to proceed to the calculation of the estimate for construction;
• highly skilled workers legally confirm their activities and are responsible for them.

If you have to replace the roof with your own hands, then you should prepare and study the regulatory framework that deals with the reconstruction of any part of the house. It is important not to delay the construction process in order to meet the three-year period when the documents were agreed, otherwise the procedure will have to be repeated. To make a really strong and reliable roof, it is important to have a very serious knowledge base so that the finished structure is not dangerous for others.

Replacement and repair of roofing can be done in two ways:

• Work immediately with the entire roof, when both roof slopes are reconstructed at once. In this case, a protective frame with an awning is erected above the house.
• Work with each slope is made separately, which allows to reduce the cost of work. No need to build any awesome awnings.

To protect the house from precipitation, it is best to choose a material that will allow couples to go out, but will not let rain fall on the surface of the house, which was left without a roof. Properly installing such protection, the repair process can be carried out in any season. Installation of an awning process is not simple and requires the knowledge and skills that real professionals have in this matter. With all the advantages of this technology, there are a number of disadvantages associated with the fact that the awning limits the working area and prevents the use of long beams and boards from which the rafters are mounted. In addition, such protection for the house requires considerable resources, which are included in the cost of repairs, and make it more expensive.

Because of this, repair and installation of roofs is often done with the help of the second option, where work is divided into stages and carried out in pieces. In this case, work is carried out only if it is warm and sunny outside. If it rained, the work stops and the open part of the roof is covered with foil.

In order to begin the reconstruction, it is necessary to conduct a full examination of the pie., built, mineral insulation and waterproofing.All elements that have reached the end of their service life must be removed, we rework the necessary parts, and only after that we do the repair. If the roof will also serve as a ceiling for the attic, and even the attic itself, then you need to take care of ventilation during construction.

Insulation, lathing and rafters should interact so that there is an air cushion between them, this will increase the insulation. The optimal value of the ventilation gap is five centimeters. It is important to keep this distance along the entire slope. It is necessary to take care of the air circulation in the direction: horse-eaves, which will save from autumn leaves and birds, looking for a refuge. The ridge of the roof should also be equipped with an aerator, which is a ventilation outlet that looks no different from the roofing material.

A very effective option for good ventilation of the space is a ventilation turbine, the rotation of which begins with any breeze of wind masses. This option will be successful for residential attic, where you can equip the attic.Due to the special characteristics that apply to this room, it is necessary to strengthen the rafters.

To stay in the attic was comfortable, it is important to take care of the insulating layer. For a pitched roof, whether it is new or one that will be reconstructed, it is best to use fiberglass and stone wool. It is better to work with plates in this case, then, as mats, from time to time can start to sag, which will give cold access to the inside of the room. From modern materials can be distinguished foam glass and polystyrene foam.

A complete list of works on the reconstruction of the roof can be represented as a specific work algorithm, which includes:

• Work with crate. If a complete rework is to be done, then the old structure is dismantled and a new one is being built. If the repair is partial, then the damaged parts change. Depending on the type of roofing, a different pitch of the batten is formed, for asbestos cement it is 75 cm, and for metal tile it is about 40 cm. The outer side of the rafters is completed with a counter grill, on which the layer of hydro and vapor insulation will be attached.
• The process of reinforcing the lathing, for which additional struts are formed, which distribute the weight differently, partially borrowing it over.

• Work to strengthen the valley and eaves overhang, where snow stagnation is most often formed. With the help of a continuous cracking, it is possible to solve possible problems.
• The process of strengthening the supporting structures rafters brackets, bolts, plates, additional racks.
• Work on the creation of roof ventilation, which can be done in several ways: creating additional windows in the roof surface or placing air vents around the eave on the outer wall; the air exchange system must be through, so that there is no accumulation of air in the “bags” and its stagnation.
• The process of insulation of the roof with the help of thermal insulation, which can be placed between or under the rafters. It is important to install a vapor barrier layer, which is further sheathed with a finishing material.

If the reconstruction is carried out on a flat roof, then it is important to properly organize the slopes along which water will drain into the drainage system.This nuance will increase the operational life of the roof and will help in a simpler and easier repair process. The simplest option to create such a slope is a wedge-shaped insulation plates that are laid on the base of the roof or a layer of insulation, it is important to make a slope of 1.5%. If it is possible to withstand such a slope, the water does not stagnate and is well discharged, which helps to preserve the roofing material as long as possible.

If the roof was not previously insulated, then to install the appropriate layers, it is necessary to completely disassemble the roofing pie. If the roof is partially insulated, the whole and uncorrupted material can be left and the rest replaced. Usually they warm the roofs, the base of which is made of plywood, OSB and reinforced concrete sheets.

For the reconstruction of a flat roof, foam concrete is an excellent material, which becomes a buffer zone for steam, which is formed from water and is evenly distributed over the entire surface of the material. This mechanism allows not to disturb the hydro- and thermal insulation, which helps to preserve the roofing fabric in its original form for many years.The effects of cold also do not have a negative effect on the surface, because the vapor particles become freezing when they become crystals, which do not harm the roof material.

The reconstruction process is important to carry out correctly, first work is done with the old roof and its covering. It is important to remove all irregularities, bends and bulges. Laying a new roof should be done on the foundation, which is already fully prepared. The first step is the installation of new waterproofing, and already on it you can mount roofing materials of any type.

If the flat roof has not justified itself and there is a need to make a pitched instead, then it is not always necessary to destroy what was, you can build a new frame over it. Rafters are farms that are made of profile. Working with them is easy and convenient, and immediately after the construction of the frame, you can mount a new roof. The profile of galvanized steel is very reliable for such cases, since it does not deteriorate due to environmental conditions, is not afraid of moisture, heat and does not burn.

Any work on the reconstruction of the roof should be reasonable, and be carried out in compliance with all rules and regulations.It is advisable to know the legal framework in order to avoid all sorts of problems. You can contact the agency for construction and repair, where professionals can help you make a plan of work, calculate the cost of materials, and if necessary do all the work as soon as possible. Although this option will cost much more.

You can do all the work yourself, the main thing is to prepare well for repair., read the literature, watch videos, and do not rush to finish everything in a week. This repair continues for a long time, but the result is worth it, with proper replacement of the roof, you can arrange a full attic room, where the whole family would be happy to be.

The details of the reconstruction of the roof are described in detail in the video.
