Damage to the roof for reasons such as aggressive exposure to precipitation, sudden temperature changes, improper installation of the roof, exceeding the maximum permissible load on the roof, and not only, is considered quite common. In some cases, the owners of houses or developers of multi-storey buildings at some point decide to completely or partially update the roof, that is, replace the old roof with a new one, a more modern or high-quality one.

Complete or partial replacement of the roof, implying the renewal of individual elements, is called professional roof repair. What technologies and materials are used for repairs and in compliance with what rules the work is carried out will be discussed in this article.

What defects are there in the roof and why a repair is necessary for it

Any roof can have defects that appear as a result of the following processes:

1. Poorly rendered services for the initial installation of the roof;
2. Errors in the design of the roof structure;
3. Operational errors;
4. Low-quality materials;
5. Incorrect or untimely repair;
6. Wear the roof structure after a certain period of time.

Possible defects and damages:

1. Leaks – These are the most common defect in almost any roof. Flat roofs are most prone to leaks. Leaks, as a rule, occur due to improperly performed waterproofing of the waterproofing of the roof;
2. Concrete damage and corrosion damage to reinforcement, which is usually characteristic of reinforced concrete structures;
3. Metal corrosion – relevant mainly for metal structures;
4. Holes and cracks;
5. Opening of folds and ridges;
6. Destruction of the paintwork;
7. Displacements of individual structural elements – are relevant mainly for roofs made of metal tiles, slate, and other piece products.

Important: Remember, small defects or minor problems in the roofing structure, without proper and timely repairs, can very quickly turn into a serious problem requiring complete replacement of the roof, major repairs or serious manipulations (reinforcement or injection), which will subsequently lead to large monetary investments.

Roofs to be repaired by type of structure

The complexity of the repair work, their cost, timing, and other various nuances, as a rule, very much depend on the type of structure or building where the work needs to be done.

The main types of buildings:

1. Private houses, private cottages, and townhouses;
2. Apartment and multi-storey buildings;
3. Panel houses;
4. Industrial buildings and warehouses complexes;
5. Administrative buildings, business centers, and shopping centers.

Each type of building has its own characteristics, which directly affect such indicators as technical regulations, deadlines, their complexity, and frequency.

Features of repairing the roof of a private house

A private house — is usually a small structure with a flat, pitched, or combined roof. It can be a private cottage or a country house. 

As a rule, in private cottages, townhouses and houses there are no regulations for planned roof repairs and the need for repairs appears mainly when people living in the house detect leaks, wetting, condensation, or other problems affecting the functionality of the roof or its aesthetic appearance (paint fading, metal corrosion, etc…).

The most common problems with roofs in private homes are their leaks, which can lead to damage to property, finishing elements, the formation of dampness, mold, and mildew. When leaks appear, the main type of repair for pitched roofs is their busting or sealing of joints, and for flat roofs, it is the performance of work related to partial or complete replacement of waterproofing.

You can read more about their repair and restoration of waterproofing in the following articles:

• Waterproofing of the roof: methods of its construction and types of materials for performing high-quality work;
• Roof waterproofing repair: Methods, materials, and prices;
• Waterproofing of a flat roof. Recommended materials, methods of their installation, and prices for work.

Professional repair of the roof of a private house includes an inspection by specialists of the coating and, if necessary, its subsequent restoration. First, the damaged sections of the material are removed, and then the complete or partial replacement of all removed elements is carried out. The work is completed, as a rule, by processing all minor defects present on the roof and complete waterproofing of the base.

When working with the pitched roof of private country houses, it is also important to pay attention to the integrity of the truss system of the house and take into account the maximum permissible load on the structure at the stage of choosing a roofing material.

For example, a sheet roof is not suitable for all buildings and can cause serious damage to the integrity of walls and floors if the load on the structure is calculated as illiterate. It is not recommended to place objects on the roof of ordinary houses, by type, pools, or flower beds with plantings, without preliminary calculation of loads and the installation of the correct roof layers.

Features of repairing the roof of an apartment building

As a rule, apartment buildings or multi-storey buildings have certain regulations for planned and major repairs of the roof, regardless of the detected problems or leaks. However, if problems with the roof of multi-apartment or multi-storey panel houses are detected, they should be immediately addressed without waiting for a planned replacement or repair, otherwise, the damage may increase and turn from a small problem into a big one.

For example, if the waterproofing of a flat roof in an apartment building is broken, water will penetrate under the waterproofing coating, and then into the thickness of the concrete floor, since concrete without proper protection is a sponge for water.

Such an impact on concrete forms pores, capillaries, and microcracks in it. If you do not take measures in time, then over time the water will penetrate more and more into the cracks that have formed, freeze in winter, and thaw in spring, which will eventually lead to these minor defects expanding and turning from a microcrack into a serious crack that can affect the bearing capacity and integrity of the structure.

In order for the roof to serve for a long time and justify the efforts spent on its repair, it is necessary to order regularly a professional inspection of the structure from construction companies.

Such a service includes an analysis of the rafter system, waterproofing, lathing (if available), the entire roofing layers, as well as the places where horizontal structural elements adjoin vertical ones. A planned assessment of the condition of the roof allows you to detect damage in time and start repairing them as soon as possible.  The most favorable time for inspection– -is the spring period after heavy precipitation.

Features of repair of the roof of an administrative building and an industrial structure

Restoration of the integrity of the roofing layers of large buildings is carried out only by proven construction companies. The technology of dismantling the roof and subsequent laying of its new elements does not differ from the standard method of partial or complete replacement of the roof. In the case of administrative buildings and industrial enterprises, construction work is usually carried out at a high altitude and should be carried out taking into account all safety recommendations.

Fences are installed on the territories adjacent to the building to prevent the appearance of accidental pedestrians in dangerous areas. As a rule, when organizing regular professional inspections of the roof, major repairs are not quite required. Only planned compensation for all damages and updating of the appearance of the roof is carried out, which does not take very much time.

Roofs are to be repaired by the type of material they are made of

Any roofing, regardless of the material from which it is made, tends to deteriorate over time. In addition, a significant role in the issue of roof damage is played by aggressive environmental factors (for example, temperature drop), illiterate installation, and improper operation of the roof of the building. Because of these and some other reasons, there is a violation of the integrity of the roofing structure. Further, we will study the types of roofing materials and the features of their repair.

Metal tile

Metal tile is a fairly reliable material made of thin sheets of metal that are coated with zinc. Galvanized steel protects against corrosion and other damages. Nevertheless, the metal tile sheets and the joints between them need high-quality waterproofing, which will not allow the destruction of the under-roof space due to the effects of excess moisture. 

Metal-based material traditionally attracts owners of private houses and developers of apartment buildings with a pleasant appearance, a rich assortment of colors, and resistance to environmental factors.

Profiled roofing

Profiled flooring is characterized by a large number of fasteners, as well as vertical and horizontal joints. For this reason, the roof of such material periodically needs repair, regardless of whether it is properly operated. 

Repair features: To restore the integrity of the roofing sheet and to fill all joints and gaps, various sealants are used, for example, silicone, polyurethane, and acrylic, as well as bitumen mastics.

Surfaced roll materials

We are talking about the so-called soft roofs and flat roofs. Surfaced products, sold in hardware stores in the form of tightly wrapped rolls, are a bitumen-based coating that is deposited on the base with the help of burners in overlap with each other. As a rule, rolled sheets, over time, swell (due to the ingress of water under the waterproofing carpet), crack, and deform. Repairs to such a roof can be carried out locally or thoroughly.

The disadvantages of the deposited sheets are mainly in the presence of many seams (joints) between the rolls and the lack of 100% adhesion to the base. Accordingly, if over time the seam has parted somewhere or a microcrack has appeared, then water penetrates under the waterproofing carpet and begins to spread under it, manifesting itself indoors in the weakest place and it is absolutely not necessary that it goes under the carpet over this place, which greatly complicates the local repair of this type of roof.

For more information about the roll and surfaced waterproofing and how to repair them, you can read the following article – Roll waterproofing installation with detailed instructions for its installation;

Instructions for the maintenance of rolled roofs can be downloaded by clicking on the link below:

• Maintenance of roll roofs. General rules for the maintenance of roofs with roofs made of rolled materials

Fold (Seam roof)

The seam roof belongs to metal and, like other metal coating options, has excellent performance characteristics. Unlike metal tiles, the seam fits tightly and hermetically and is fixed in a hidden way, eliminating the need to use self-tapping screws. Therefore, moisture does not penetrate through the mounting holes and does not fall under the roof space of the roof.

A folded sheet can cover complex areas, for example, domed or bilbous. Also, the fold is characterized by a long service life, lightweight, a huge variety of colors, and resistance to the effects of environmental factors. This roofing is perfect even for roofs with a slope from 3 to 16 degrees.

Membrane roof

Membrane roofing is used to protect roofs from the effects of precipitation, and the environment. Holes and scuffs appear on them much less often than on other compositions, and with proper installation and proper care, the seams between the membrane sheets may not diverge for more than ten years.

However, no one is immune from unpleasant accidents and the human factor, so periodically the membrane roof needs repair. And here we can highlight another obvious advantage of such a high-quality, albeit expensive material: the repair of the coating is carried out quickly, using a minimum number of tools, and does not require huge costs.

For more information about roll and membrane waterproofing and methods of its repair, you can read the article  – Membrane waterproofing: Types of materials and methods of their installation.

Copper roof

The copper roof has a lot of positive characteristics. For example, copper has a long service life, ease of installation, resistance to corrosion, temperature changes, and moisture, high fire resistance, as well as ease of repair. Restoring a copper coating is as easy as metal tile coating.

 The only drawback of this metal is its inevitable fading over time: due to the effects of oxygen and humidity, copper first acquires a brown and then a greenish tint, which is explained by oxidation

Composite roof tiles

Composite tile – is a durable and reliable material used everywhere to protect roofs from various environmental influences. This material is based on thin sheets of steel coated with an alloy of aluminum and zinc, and outside the composite tile is processed with small granules of natural stone and sometimes with a protective acrylic glaze of various colors. Thanks to this structure, the metal component of this tile are reliably hidden from the eyes of the observer, as well as the stone coating perfectly protects the roof from the effects of wind and precipitation.

As a rule, composite tile sheets are made in accordance with the size regulations: their length is 140 sm, and the width can be different. Fluctuations in the thickness of steel sheets, according to GOST, should not exceed 0.1 mm. Such a tile has high strength and is fireproof. This is due to the fact that the composition of the acrylic coating includes silicone that can withstand temperatures up to 135 degrees. This is an excellent indicator because it means that composite tiles will be able to withstand open fire for at least 6 hours.

Composite tiles are made in such a way that they do not emit any toxic substances when heated by sunlight. Moreover, it is characterized by high elasticity and good thermal conductivity, which means the need to install insulation deep into the roofing layers. And the service life of the composite composition is determined by the thickness of the aluminum and zinc coating. For example, if there are 190 grams of aluminum zinc per 1 squire meter,  then the manufacturer guarantees at least 50-year service life of the tile.

Ceramic tiles

Another subspecies of tile, namely the ceramic version, is also often used for roof decoration. Among its characteristics are a lot of positive properties, for example:

• Resistance to any climatic influences, including wind, frost, ultraviolet radiation, and precipitation;
• The ability to natural ventilation through micropores, thereby reducing the likelihood of mold and mildew formation;
• Fire resistance and ability to tolerate exposure to direct sunlight;
• Long service life: ceramic tiles retain an attractive appearance for several decades;
• This material is also characterized by high rates of heat and sound insulation so that the residents of the house will be reliably protected from the cold and extraneous sounds;

However, ceramic tiles have their drawbacks. For example, ceramic tile sheets have a lot of weight, which increases the load on the truss system and the structure of the house. It is quite possible that for the installation of such tiles, additional reinforcement of the lathing will be necessary. In addition, the process of laying ceramics involves contacting a construction company with similar services and even ordering special equipment capable of lifting heavy sheets onto the roof.

Repair features:  Repair of ceramic tiles involves removing the damaged part and replacing it with a new element.

Metal

The subspecies of metal roofs include folding, corrugated board, and metal tiles, which were discussed a little earlier, as well as sheet metal, such as copper, aluminum, iron, and stainless steel, which is well known to everyone. Metal is a rather demanding coating that needs to be properly installed, properly operated, and regularly treated with protective emulsions.

Also, on roofs covered with metal, it is categorically contraindicated to install objects that need the regular attention of people, for example, gardens or vegetable gardens. Otherwise, cracks and scuffs will quickly form on the metal, and the roof itself will soon lose its appearance and become unusable.

Onduline

Onduline is a profiled sheet made on the basis of bitumen and cellulose. Sometimes Onduline is called a euroshifter. It is used everywhere and is characterized by an acceptable cost, but this is far from its only positive property. For example, Onduline has high heat and noise insulation, does not conduct electric current, and is characterized by excellent water resistance, as well as the presence of a corrugation that provides ventilation of the under-roof space.

Unfortunately, the material under consideration also has a number of disadvantages. It is not durable: its service life is approximately 15 years. After this time, the roofing should be completely replaced, that is, most likely, a major repair of the roof will be necessary. In addition, onduline is unable to withstand significant temperature changes. Frost makes it brittle, and under the influence of heat, Onduline sheets begin to melt, which is why it is quite difficult to choose the time of year suitable for carrying out work on its installation and repair. Among other disadvantages of Onduline: fire hazard, fading under the influence of sunlight and rough, and preventing snow from falling off the roof.

Roof repair works: Types of work performed and their features

Professional repairs, which according to their characteristics are divided into current, emergency, and capital, may need absolutely any design, starting from a two-storey private house and ending with a large apartment building or even a large apartment building, an administrative building, or even an industrial enterprise.

The quality of work on the restoration of the roof is affected by the initial stage of repair, namely professional inspection of the coating and drawing up a plan of further action. This process would be best entrusted to representatives of a construction company whose specialization is performing this type of turnkey work.

The urgency of the repair is divided as follows:

• Current repair and restoration of the roof – imply the replacement of less than 40% of the total surface area of the roof. Such work is organized in case of minor damage to the roof and only in cases where it is a roof and only in cases where it is possible to uniquely identify the damaged areas and/or places of leaks.
  
• Major repairs – are carried out when more than 40% of the surface is damaged, and are carried out in three stages: removal of the old coating, cleaning and processing of the work surface, and laying of a new roof.
  
• Emergency repair – is used, as the name implies, in emergency situations, and the amount of work varies depending on the percentage of damage.

Repair technologies vary depending on the material from which the roof is made. With some, you need to be extremely careful, while others withstand serious mechanical loads. What is the repair features characteristic of different materials?

Repair of a flat roof

A flat roof — is a structure where there is no slope or there is, but a very small one. This type of roof is highly susceptible to precipitation, as they have the properties to linger on the surface, creating pressure on the completed waterproofing system. In the absence of high-quality insulation, water penetrates into the roofing layers and begins to destroy gradually the concrete base, leading to wetting, leaks, increased moisture, fungus, cracks, and corrosion of the reinforcement.

The scheme of the arrangement of a flat roof

For more information about the repair and waterproofing of a flat roof, you can read in the article – Waterproofing of a flat roof. Recommended materials, methods of their installation, and prices for work.

Most often, the protective coating of a flat roof is made of the following materials:

• Surfaced rolls based on bitumen
• PVC, Air defense, and EPDM membranes

Features of repair of surfaced or soft flat roofs:

By the nature of leaks in the room under the roof, it is sometimes very difficult to determine the place where it comes from the outside, since the surfaced products do not have 100% adhesion to the base and water can walk under them. That is why, in the presence of this type of roof, it is recommended either to remove it completely by installing a new coating or to apply a new layer of surfaced material or compositions like liquid rubber or polyurethane to the entire existing base.

If it is impossible to carry out major repairs, it is possible to perform local repairs of damaged areas by local opening and installing the so-called patch.

Scheme of local repair of a soft rolled roof:

For more information about the roll and surfaced waterproofing and how to repair it, you can read in the article – Roll waterproofing arrangement with detailed instructions for its installation.

Features of repair of membrane flat roofs:

The most common types of damage to the membrane roof are sheet cuts and divergent seams between these sheets. In both cases, membrane patches are used for the existing membrane using hot or cold technologies.

The first technology involves cleaning the damaged area and fixing a patch to it using a welding dryer. For better fastening, the membranes are passed through the patch with a roller. The dimensions of the new section of the membrane should be 5-10 sm larger than the damaged area on each side.

In the second method, cold, standard construction glue will be used. First, the work surface is also cleaned of any dirt, the patch is fixed to the damaged place, and its edges are rounded beforehand a sealant is applied around the perimeter of the patch, which is distributed using a roller.

Work on the local repair of the membrane is carried out by installing patches in damaged areas. At the same time, it is important to note that the membrane roof is laid on the base with one large carpet made of different rolls, fastened together with a special drier, glue, or installation. At the slightest microcrack, seam, or joint, water gets under the membrane and spreads freely under it, manifesting itself in the weakest place. This fact in most cases does not make it possible to perform high-quality local repairs and eliminate leaks to the need for a complete replacement.

Repair of metal tiles

In case of damage to metal tiles, both current and major repairs are carried out quite easily. The sheets are either removed from the roof and then replaced with new ones, or processed as necessary. If a hole is formed on the metal tile, a patch is made of the same material, which is placed on top of the sealant layer. Especially dangerous elements of the roof that require increased attention are the ends, from which sheets of metal tile often depart with insufficient strong fixation. 

Important: As a rule, when problems are detected, damaged or incorrectly installed sections are moved again. Sometimes problem areas are covered with special waterproofing mastics.

Repair of the roof from different types of tiles

Shingles are considered as a material on which it is quite easy to detect damage. A positive feature of the tile is that it takes no more than a few hours to repair most of the damage. 

For example, damage to individual sheets of ceramic, composite, metal, or other tiles can be eliminated by simply replacing the affected part with a new one. The old element is removed, the area under it is cleaned and prepared for fixing a new tile sheet, and then this sheet is fixed to the roof.

In case of minor defects, you can completely refuse to replace the tile sheets. It is enough to treat the damaged element qualitatively with the help of a roofing sealant or adhesive composition. However, if several tiles are damaged at once, it would be best to sort out these areas and replace the sheets with new ones, rather than trying to treat them with a sealant.

If the problem is a violation of the integrity of the waterproofing layer, then it is necessary to carry out simple manipulations. First, the gap is treated with putty, after which a new protective layer is applied, designed to protect the roof from moisture. After installing the protective layer, the resulting seams can be painted: this will make the appearance of the roof more attractive.

There may well be damage to the ridge roof made of tiles. In this case, the repair or replacement of the skates is carried out, as well as the correction of the geometry of the roof, that is, the installation of additional reinforcement. To do this, it is necessary to remove the roof and the lathing, install the beams on the rafter system and assemble the entire roofing layers back. If a violation of the integrity of the roof is found in the depth of such a layers, then it will not be possible to solve the problem, otherwise than by disassembling the roof.

Metal roof repair

Repair work aimed at restoring metal roofs is best trusted by professionals since metal sheets are quite fragile and require careful treatment and ideally are for the use of specialized equipment.

In the case of a seam coating, it can be quite difficult to detect damage. The problem may lie both in the joints and junctions, and in the folds themselves, and be so small that it will be almost impossible to detect it. Then an experienced damage analysis is used, namely, observation from inside the room of the areas and the nature of the resulting leaks.

When the damage is detected, there may be several further scenarios. Or seams and joints are processed using, for example, sealing tape. If the problem is in the folds themselves or in their connection, it is necessary to remove the roofing material, clean the roof base, and lay the roof again.

In addition to the sealing tape, rubber cords, roofing sealants, and paints based on liquid rubber or polyurethane are used to compensate for damages that do not require the removal of the elements of the seam roof. The latter option is perfect for eliminating local damage that does not affect the condition of the roof.

Compared with a seam roof, the profiled roofing is difficult to install and operate, since it has a large number of additional elements, for example, fasteners. To date, both superficial and deep damage to profiled flooring is quite common, requiring varying degrees of attention. To repair such a roof, sealants and mastics are used, which fill through holes, gaps in the joints, cracks, crevices, and many other disadvantages.

Important: Special polyurethane waterproofing compounds can be applied locally or completely to metal coatings, which protect the metal not only from water penetration, but also from exposure to ultraviolet rays, corrosion and fading. If certain sections are deformed, their local dismantling and installation of a new one is also allowed. When carrying out spot repairs, special tapes are also used for processing joints and seams.

Repair of slate roof

It is quite simple to detect defects in the slate coating. The problems that indicate the need for repair include cracks on the upper and lower waves of the sheets, as well as across the waves, cracks in the slate coating, chips formed as a consequence of the snow-rich winter, as well as moss that corrodes the slate.

There are several ways to restore a slate roof. For example, bitumen-based compounds-resins and sealants are widely used. The resin, heated to 150 degrees, is poured into the cracks formed between the sheets and forms a waterproofing film, and the sealant is able to seal the cracks and eliminate the need for additional sealing of the treated gaps.

If the damage is more significant, slate sheets are replaced, which requires at least 2-3 people due to the heaviness of the material. The elimination of damages on the slate coating is also carried out using self-adhesive bitumen-based tapes and roll membranes.

Such compositions are universal and are able to cope with the restoration of any surface. If we talk about more premium and durable options, then it is recommended to use polyurethane waterproofing. In the case of a large area of damage, patching technology is used, that is a patch is made from a slate sheet, which is superimposed on the damaged area.

The working area should be treated with a sealant beforehand. It is worth nothing that not only the slate itself but also the profiled flooring and even onduline will be suitable for making the patch. Also, slate, which is unsuitable for the effects of moss, should be regularly cleaned of vegetation using special solutions. Lichens, moss, and mold are softened and then removed with a brush with the addition of a small amount of water. To prevent the appearance of moss, a primer will help, as well as cover the roof with atmospheric acrylic paint or polyurethane.

Prices for roof repairs depend on its type

The price for the repair of various roofing structures depends on the type of repair structures provided, the materials used in the repair, as well as on the type of roof itself. In addition to the above-mentioned factors, prices may also be affected by the complexity of the work, weather conditions, and other factors. 

Below is the price table, which shows prices taking into account standard indicators. The final prices will be provided by the estimating department in the form of a detailed commercial offer, where the prices for the works and the materials applied to them will be indicated. The final calculation of the price is possible only after the departure of the engineer to the facility, for visual inspection and registration of various nuances that may affect the final price or the final list of works.

What is the best way to choose a leak repair – Major or local?

Most types of roofs are made of materials that do not have full adhesion to the base, which means that when water penetrates under the insulation layer, it can safely move from one place to another. Further, the water that has fallen under the protective carpet goes along the least resistance and manifests itself in the form of a leak or a wet spot in the weakest place.

As you have already understood, the manifestation of water in a certain place absolutely does not mean that it got there from the roof area above this place. It follows from the above that in most cases, when performing local work, you may simply not guess the place where the water comes in from the outside, despite the fact that it seems to you that it comes in there.

When it is worth trying to solve the roof problem with local repairs:

• There are several visible defects that apparently pass water (destroyed areas, incorrectly made joints to protruding elements, incisions, and cracks);
• Small cash budget;
• Unused premises (there is no risk of the destruction of expensive finishes or furniture);
• There is an opportunity and time to try to solve the problem with local manipulations;
• A guarantee for the absence of leaks is not necessary.

When it is better to choose a capital solution:

• Need a long-term warranty against leaks;
• If problems reappear, expensive furniture or decoration may flood;
• It is desirable to make repairs once and forever.

Important: In most cases, when performing local work, no company that respects its name will give you a guarantee that there are no leaks. Any professional understands that he has not installed the roof and, having eliminated even an obvious defect, he can not be sure that the rest of the roof is made without violations and is in perfect condition. There is no guarantee that the water will not find another place in the roof and will not pass inside the roofing layers exactly there, and then come out in a new or in the same weak spot from where it came out earlier.

Turnkey roof repair

It is rare when customers of services related to the repair or replacement of the roof want to hire several different companies to carry out the final repair, for example, one company re3moves the old coating, the 2^nd organization performs waterproofing, the 3^rd one builds the rest of the layers, etc…, it is more profitable and technically correct for the Customer to give all the necessary work to one turnkey hands.

The technical correctness of ordering the repair of the entire roofing layers turnkey from one organization is due, among other things, to warranty obligations, for example, for the absence of leaks. When dividing the work on the waterproofing arrangement and, for example, laying thermal insulation or screed on top of it, upon the occurrence of warranty obligations, the company that performed the work on the installation of insulation may accuse another organization that performed the work on laying insulation on the insulation performed, that it was this company that damaged this work.

Turnkey roof repair services include the following stages of work:

1. Departure of a specialist to the facility for a thorough inspection of the roof, its defects and possible solutions;
2. The visiting specialist offers various technical solutions for the performance of work related to the repair;
3. The estimating department calculates all the options indicated by the visiting engineer and sends them to the customer for consideration;
4. After choosing a certain solution, an official contract is signed between the parties, where all working conditions, services provided, terms, prices, and warranty obligations are prescribed;
5. The exit of the working link led by the engineer and foreman to the facility;
6. Execution of all turnkey works starting from the dismantling of the old foundation and ending with the complete construction of the roofing layers.
