Prerequisites for radical measures

Everyone agrees that flat roofs are appealing in terms of cost and structure. Without a doubt, unskilled home craftsmen and "left" construction brigades start their construction without a clue about the guidelines and construction principles for flat roofing systems. Such sculptors’ technologies are cruelly violated, which invariably produces unsatisfactory outcomes, such as:

• Wetting the insulation. The reasons are in non -compliance with laying layers of the roof pie and in the low quality of the compounds of the waterproofing carpet. Wet thermal insulation is significantly heavy and loses the technical characteristics laid down by the manufacturer. Weight increase is extremely undesirable for roofs with a base from corrugated board, which is tritely deformed and sags from overload. A wet environment contributes to the appearance of a fungus that pose a threat to the base and walls made of any building material. Due to the wetting, insulating qualities of insulation are reduced by half at least.
• Stagnation of water rain and talus type. Accompany the non -compliance of the slopes of the flat roof directing atmospheric water to water intake funnels and gutters. The formed puddles are very favorable for the origin of the flora, actively destroying building materials that are not adapted to the neighborhood with it. With a sharp drop in temperature to minus marks, stagnant water will simply tear the coating.
• Vimitation of the roofing carpet. It occurs when an excess of pressure in a roof pie. The phenomenon is associated with the illiterate distribution of layers and with an incorrectly calculated thermal insulation thickness. The consequence can be not only the appearance of numerous bubbles, which it does not make sense to eliminate in separate. The coating may crack from an excess of pressure.

The reasons mentioned below are a result of roofers’ subpar work. In actuality, there are far more detrimental effects of careless work. Only those that result in drastic changes have been mentioned; strategies for preventing damage that can be predicted with certainty are provided in a different article.

In addition to compromised technologies that interfere with the roof’s regular functionality, improper material selection also plays a role. For instance, the coating will lose plasticizers if the PVC polymer membrane comes into direct contact with heaters made of polystyrene or polyurethane. Glass chloride must be laid in order to prevent a membrane and isolation.

The roof will need to be repaired well before the manufacturer’s promised deadline if the required dividing layer was not supplied. Furthermore, nobody offers to make up for the damage to the coating caused by a poorly constructed roofing pie. Additionally, if the membrane is covered with an outdated bitumen carpet that lacks a dividing element, you shouldn’t expect a refund.

Bitumen or bitumen-polymeric materials make the perfect vapor barrier layer for bituminous roofs with a concrete base. Without a dividing layer, the regular polyethylene on the concrete base cannot be placed. The only thing that is inappropriate is glass chlower. Cement milk corrodes him ruthlessly. Both vapor barrier options are appropriate for membrane-coated roofing, however polyethylene is preferred because of its lower cost.

Applying a polymer coating over a rough base is prohibited. It is imperative that the roofing system not come into contact with sharp objects that could compromise the material’s integrity.

It is imperative to keep organic solvents, oils, fats, and agents containing gasoline off the roof. Preventing plant rooting, dusting off of the roof, and excessive movement in areas not meant for heavy roofing operation are all necessary. non-adherence to the regulations Capital repairs using a cardinal transformation are the fatal outcome.

Apart from the eloquently detailed requirements for reconstruction, there is one other template reason: the collection. Climate factors are acting intensely, causing the roof and litter layers to age.

The device’s materials need to be completely replaced because they are no longer aesthetically pleasing and have poor technical qualities. The outdated roofing pie isn’t always changed, though. A new system is installed on top, or a superstructure in the shape of a pitched roof is constructed, if it is in good condition.

Options for reconstructive technologies

Selecting the best technique for comprehensive flat roof repair is entirely personal and is contingent upon several favorable factors. The building owner’s financial means, their desire for extensive renovations, and the extent of the roofing system’s damage are among the influencing factors.

We categorize the fundamental reconstruction techniques into the following kinds in light of the variations in the tasks given:

• Complete update of roofing pieA. It is carried out when the thermal insulation is wet due to the absence, incorrect laying or damage to vapor barrier.
• Updating insulation and waterproofing coating. Performed with irrevocable damage from getting wet of thermal insulation due to impressive damage to the waterproofing carpet.
• Roof reconstruction with an additional insulation device. Realize in the case of an insufficiently favorable microclimate in the internal premises of the structure.
• The device is slopes. Conducted when the stagnation on the roof is formed, on which during the construction period they did not make a rally.
• Building in the form of a pitched roof. Carried out with the aim of forming an attic or a residential attic, if the initial construction of a flat roof was considered as a stage to further restructuring of the building.

The technological and financial aspects of flat roof reconstruction techniques vary greatly. You must fully acquaint yourself with the sequence and volume of actions before using any of them. You should rationally evaluate their own abilities, the object’s condition, and the expediency with great care.

Flat roof reconstruction methods

Based on his personal preferences and the signs mentioned above, the owner must choose which of the two methods of complete alteration to prefer. Our job is to provide flat roof restoration and overhaul options so that the best option can be thoughtfully selected.

Complete update of the roofing pie

The age of construction and the roof’s service life are not always direct indicators of when the roofing system needs to be completely updated. Despite numerous lantings and the master’s enormous efforts, the new design is freely flowing while the old design can obstinately withstand atmospheric attacks. But before you begin, it’s a good idea to check how long the manufacturers of the materials say the roof will last and how long the old house can still be used.

The algorithm used to update a flat roof’s roofing is as follows:

• We dismantle metal strips holding the roofing on vertical planes, aprons, cuffs.
• Remove the additional hydraulic tank laid along the adjoining and around the roofing.
• We delete fillets installed along the line of conjugation of vertical surfaces with the plane of the roof, remove the roofing funnels and details of the passages.
• Eliminate the spoiled roofing, insulation, then a vapor barrier layer if it was.
• We cleanse the base of dust and pollution formed during the dismantling period.
• We reimburse the surface prepared for work.
• We lay a vapor barrier layer selected in accordance with the type of base. On a concrete basis, we melt the bitumen waterproofing, warming up the back of the roll material with a gas burner. On the profiled by the profile, released from the roofing system, we put a plastic film with an overlap of contacting canvases. Polyethylene vapor barrier sheets are carefully glued with tape so that it turns out a whole hermetic canvas. The vapor barrier layer is laid down on vertical walls. The result should be a semblance of a pallet with sides, the height of which is 5 cm larger than the thickness of thermal insulation.
• We lay the thermal insulation, the thickness of which we calculate in advance according to the instructions of SNiP 23-02-2003. In mechanical systems, we fasten the slabs with two self -tapping screws with plastic telescopic fungi. In ballast analogues, we fix the insulation only along the overhangs, if there are, parapets, walls and around passes at the rate of 3-4 fasteners per meter. When arranging adhesive brothers, we act according to the name.
• We mount the fillets to the previous places and glue the additional waterproofing carpet along the lines of conjugation.
• We lay the selected type of waterproofing coating. In the process of laying, we mark the place of overlapped passages on the material. We put bitumen roller materials in 4-6 layers, we fuel or glue in accordance with their technical category. We put the membrane coating in one layer. The waterproofing coating is laid with a vertical plane of 10-15cm.
• We cut the material cruciate in the places of roofing passages, install waterproofing cuffs, then water intake funnels and t.D.
• The edges of the bitumen waterproofing carpet are fastened on vertical walls with metal strips, the edges of the membrane carpet are glued with glue specially designed for this procedure.

The modern bitumen roof needs to be shielded from high steam pressure. In reconstructions, the waterproofing coating’s lower layer is partially bonded using stripes in accordance with the breathing system principle. As a result, strange concepts arise that aid in the condensation of steam from thermal insulation. There are installed vapor-outlet floods in addition to the entire area.

With a diffusion membrane, the suggested precautions are not required. She passes the extra steam freely, no further ploys or gadgets.

Variations on the topic of update

If the vapor barrier layer was expertly chosen, flawlessly applied, and undamaged, a similar, albeit somewhat shorter, cycle of work is completed. Due to poor panel connections or damage to the waterproofing carpet, thermal insulation became wet.

In the event that localized repairs involving opening swollen areas and drying the insulation proved unsuccessful, the damaged coating and thermal insulation should be removed. Once the base has dried, new roof pie layers should be installed using the procedure outlined.

Only roofing needs to be removed in order to reconstruct a roof without water outflow slopes. Employing wedge-shaped insulation plates to complete work on the arrangement of inclinations to internal or external water receivers makes more sense. With pre-made roofing racket solutions, you can quickly reconstruct a flat roof without incurring high labor and material costs.

A similar plan calls for an improvement in the roofing system’s thermal insulation layer. Prior to work, the waterproofing carpet and roof accessories are removed. Slabs of thermal insulation are installed over the current insulation layer. The upper layer’s mineral components must have a stiffness of at least 60 kPa.

It is important to arrange the newly formed thermal insulation layer so that its seams don’t line up with those of the layer underneath. According to custom, the insulation is fixed using a mechanical, adhesive, or ballast method.

After thermal insulation is complete, a brand-new roofing carpet is installed. Remember that mineral wool can be covered with bitumen coatings and a membrane without the need for separating layers. The membrane can only be applied to polystyrene foams if a glassoluste or geotextile preliminary device is used as a dividing layer.

It is necessary to insulate a flat roof that lacked thermal insulation when converting non-residential construction into a heated workshop, garage, or summer temporary assistance. An extensive repair of this kind is comparable to a brand-new flat roof pie. The waterproofing carpet is removed, and then work is done starting from scratch.

Initially, a vapor barrier is installed, with the type of barrier determined by the base. Applying bitumen or bitumen-polymer vapor barrier material to the concrete surface is preferable; however, using polyethylene to arrange a roof with a corrugated board base is more cost-effective. Next, the heat-insulating layer is constructed, with its thickness predetermined. A waterproofing carpet is placed at the conclusion.

Applying foam concrete on top of the renovated roof is a practical method of rebuilding the flat roofing system. Furthermore, a roofing pie that has been moistened doesn’t even need to dry before work begins. Because steam in the concrete will participate in the hydration process as it migrates from thermal insulation to a monolithic fill. A waterproofing carpet can be placed over a layer of foam concrete without risk of it swelling. There is a belief that vapor barriers are unnecessary in these types of roofing projects.

Ballast roof instead of the old

A boring exterior can be brought back to life by changing an ordinary flat roof in a sports area, patio, or green lawn. Wear or marriage in the roof structure is not always the reason for such a reconstruction. In accordance with a recently installed roofing system, you can construct a green roof. The most important thing to do is figure out how the supporting structures—such as the substrate, paving, and thermal insulation—stablely support a pretty impressive mass.

The green ballast roof weighs between 50 and 70 kg per square meter on average. If the operated roof is to be built, then a person’s weight should be added to the mass of the roof pie and the local snow load.

It is important to carefully repair the existing structure before constructing a gravel tribeler or green roof. Should restoring the outdated system prove unfeasible, it ought to be eliminated entirely.

There are two types of ballast roofing systems available:

• Traditional. Characterized by placing ballast on top of waterproofing that protects the insulation. Most often, in traditional options, gravel or small pebbles are used as ballast. The scheme is convenient for quickly reworking a newly laid or well-repaired roof.
• Inversion. Characterized by placing ballast on top of thermal insulation, but between them a separating layer of geotextile or fiberglass must be laid. In this case, the waterproofing is laid under the insulation, thanks to which it also functions as a vapor barrier layer. Thermal insulation in an inversion scheme must be waterproof, which is why extruded polystyrene foam is used. The scheme is convenient for the installation of operated roofs on the base completely freed from the old system.

There are operational and non-operational subspecies for both varieties. The inversion scheme is mainly followed when installing green roofs. It is evident that they can only be arranged in a specific manner. On the operated roof, wooden flooring, paving slabs, etc., can be used in place of the soil-lowering layer.

Remembering to the rafter structure

A device with a rafter structure placed on top of a flat roof makes an excellent foundation. Actually, there are small inclines on this floor that point in the direction of the water’s flow.

They are constructed with a flat roof in mind.

• Rafter roofs without an attic. Helmes, one- and gable. The purpose of their installation is to ensure spontaneous drainage of atmospheric water and in a mild modernization of the building.
• Attic rafters. Broken, holm, one- and gable. They are built to increase the useful space of the house, t.To. Such a method does not need to obtain permits for reconstruction.

The technology consists of the basic installation of the desired type of rafter system on a flat roof. The construction can be based on the existing parapet if its walls are tall enough.

The reconstruction of flat roofs is a major development in the field of roofing solutions. The procedure entails extensive modifications that extend beyond simple surface fixes and include the waterproofing system and the entire structure. Reconstruction is an option for property owners who want to ensure a more dependable and long-lasting roofing system by addressing long-standing problems like leaks, water pooling, and structural integrity.

The secret to a reconstructed flat roof is careful planning and execution. It starts with a comprehensive evaluation of the state of the current roof, pinpointing any weak points and possible areas for repair. After that, a customized rebuilding plan is created, accounting for elements such as building supplies, drainage schemes, and insulation needs. By taking a proactive approach, the roof performs better and lasts longer, requiring fewer repairs and maintenance over time.

The reconstruction of flat roofs has been completely transformed by the latest developments in roofing materials and methods. Property owners now have access to a wide variety of materials that provide exceptional weather resistance and durability. Modified bitumen, EPDM rubber, and PVC membranes are examples of options that offer durable solutions suited to particular climatic conditions and structural needs. These materials support sustainability and energy efficiency objectives in addition to improving the roof’s visual appeal.

In the end, making an investment in flat roof reconstruction is a proactive measure to protect a property’s long-term functionality and value. It not only fixes current problems, but it also gets the roof ready to face new ones in the future. Property owners can strike a balance between performance, durability, and cost-effectiveness by utilizing contemporary technologies and materials, guaranteeing security and peace of mind for years to come.
