Knot of metal

It’s critical to comprehend the significance of each component when it comes to roofing. The metal roof knot is one such crucial component that is frequently disregarded but is necessary for the stability and longevity of the roof structure. This tiny but important component keeps the other roof components securely in place so they can endure the weather over time.

The metal roof knot connects various roofing system components by acting as a connector. Usually constructed from sturdy materials like galvanized or stainless steel, it offers protection from elements like wind, rain, and snow. It strengthens the roof’s overall integrity, guards against potential damage, and ensures structural stability by securely fastening components like support beams, trusses, and roof panels.

Resistance to corrosion and deterioration is one of the metal roof knot’s main benefits. This feature is particularly crucial in humid and wet climates, where conventional materials may eventually deteriorate. Homeowners can greatly increase the lifespan of their roof and save maintenance and repair costs by selecting a high-quality metal knot.

In addition, the metal roof knot’s installation and design enhance the roof’s visual appeal. Thanks to recent developments in roofing technology, knot designs can now be subtle and elegant, blending in perfectly with the building’s overall aesthetic. This visual integration guarantees a harmonious appearance that matches the building’s architectural style in addition to improving curb appeal.

Types of Metal Knots Common Uses
Slip Knot Basic knot for temporary metal fastening
Clove Hitch Secure knot for metal wires or ropes

We examine the complex function of metal fasteners, sometimes referred to as the "knot of metal," in roofing at "All about the roof." These essential elements improve weather resistance and durability while also securing roofing materials. We learn about the types, advantages, and methods of installation of these fasteners and how important they are for preserving structural integrity and protecting against adverse weather. Your roof’s lifespan and performance can be greatly impacted by knowing the significance of these little but powerful components, whether you’re a homeowner or a roofing expert.

Metal tape roof – reliable protection of a country house

For continued efficient operation, it is equally important to install all of the metal roof pie components while working on the roof’s construction.

The installation of the additional roof components, the spillway system, and the pediment bearings constitute the last step, after which the metal roof is deemed complete.

The device of roofing nodes

It is not always the case that the installation of metal tile sheets comes before the device on the premature elements’ roof surface. As per the construction guidelines, a portion of the metal tile roof nodes must be installed either prior to or concurrently with the main work.

Differentiating between the following structural roofing nodes is customary:

Cornice node and cornice strip installation

The purpose of the cornice is to seal off the roof’s base. It shields the rafter system from outside threats. Before beginning to fasten the metal tile sheets, raise the cornice.

Usually placed on overhanging overhangs, a solid crate has cornice strips fastened to its first board. Roofing screws with a neoprene gasket are used to secure the strips; they are twisted after 20 to 30 centimeters and overlapped by 10 centimeters.

Counseling! Adherence to overflow is imperative in order to avert plank vibration during gusts of wind.

It is advised to set the comb an overhang to the cornice length in addition to cornice strips. The lattice design will allow ventilation while shielding the roof from bird penetration. This component is particularly crucial when working with high-profile metals.

Upper and Lower Endovs are the End Nodes.

The yendovs are fastened with roofing screws in a step of 30 cm, just like the cornice strips, with a 10 centimeter overflow between the fasteners. The sealing tape is used to improve sealing.

The upper Endova is affixed to the metal tile upstairs, while the lower one is nailed to the crate. You can fasten yends with special brackets. The gap between the yendov and the metal tile should be noted. Since the cut sheets are typically positioned where the apples are fastened, they are covered with mossy decorative strips to provide protection.

Crucial! Under every yendov, extra boards must be installed! Every extra component for metal tiles is put in overlapping fashion, and a continuous crate should be placed underneath them all.

Metal tile front-line unit with wind or end strips

The planks for the right and left pediments are used to complete them. Starting from the bottom, the strips are mounted with a 10-cm overlap. installation of the strips following the installation of each metal tile sheet.

Metal tile wind bar

In particular, if the metal tile sheets were cut, the strips need to completely enclose the edges of the sheets. With the required institution on the waterproofing film board, the front-line bar is nailed to the windboard.

The primary function of the metal tile end bar is to keep wind from entering the roof structure, although it also serves as a protective element for the crate, insulation, and rafter system.

When metal tiles are nailed, the wind bar should reach the top of the wave; screws are fastened to both the side and the top of the bar. It is advised that wind plane overlap rise to 50 centimeters.

Halled node: next to the roof’s sloping areas

Wherever the bearing wall is adjacent to the roof of a house, garage, outbuilding, or terrace, the metal tile outlet knot forms. A metal profile that matches the metal tile’s color is used to make the adjustment.

A sealing tape is used to secure the waterproofing film to the wall at the designated spots. The ventilation gap between the film and the wall is visible.

The adjacent bar is fastened to the top of the metal tile with a 10 cm overlap. The seal is placed between the bar and the roofing.

The top portion of the roof, or skate node

In the final turn, skate strips are put on a metal tile roof. When installing, pay close attention to any ventilation gaps and place a sealant between the tile and ridge. The skate bar is fastened with a 10-cm overlap, and screws are added after that distance.

It is traditional to nail the skate block to the upper section of the roof at a distance of 50 centimeters.

Under the skate bar, metal tile sheets are connected, but they are not sealed together; there is a 20–25 cm gap. The mesh air element is fixed to protect the cornice and roof from precipitation.

Pipes for ventilation and smoke

The attic windows and the chimney’s passage through the metal tile should be equipped on the roof with extra care. The so-called "apron" is made twice around the pipes: once before metal tile sheets are installed, and once more on top of them. There should be a continuous crate surrounding the pipes.

Going through a tile made of metal

First, a strobe is made around the pipe’s perimeter, excluding the seams in the masonry. A thick ribbon is used to seal the area between the pipe and the crate. The upper portion of the bar is inserted into the strobe, and the "aprons" are wider than 20 cm from the smooth roof sheet. The crate and pipe are fastened with self-tapping screws.

Take note: The upper "apron" is not installed in a metal tile incision designed to keep water out of the roof structure.

Additional elements of the roof of metal tiles

Snow retainers are essential components of a metal tile roof that must be installed. It is particularly crucial in snowy winter weather that the snow is dispersed throughout the slopes rather than avalanching off the roof or falling over the house’s entrance. The length of the slopes, the slope of the roof, and the quantity of snow sediments present during the winter months all factor into the calculation of the required number of snow retainers.

Elements with tabs for metal tiles

Moving will be necessary in order to perform maintenance and a preventive inspection on the roof. guarantees the safe transportation of roofing fences or supporting components during installation.

Producers of metal roof tiles also provide their products for use on ventilation ducts, smokers, and television antenna outputs.

Depending on the customer’s preference, pre-order metal tile components based on specific dimensions or purchase standard components. Most of the time, the strips and skates are not larger than 3 meters at the factory. Premature elements typically have colors that match the metal tile’s color.

The caliber of roofing work determines how sealed the metal tile roof will be and how long the roofing will last. Therefore, when installing any premature elements, keep in mind that their installation is what determines the roof’s integrity. It is crucial to follow the guidelines for all additional strip overlaps, tighten the screws to the correct spacing, and inspect the roof as a preventative measure.

Safeguarding a home from harmful environmental elements, making sure a heating and ventilation system is operating efficiently, and establishing a microclimate that is conducive to life

Step -by -step technology for the device of metal -based roof

Installing a high-quality metal tile roof requires a thorough understanding of work technology, proficiency with locksmith tools, and preparation of all required materials. The detailed instructions for the entire technological process are provided below. DIY roofing roof is installed (though multiple helpers will still be required for moving and delivering metal sheets to the location of fastening).

The main characteristics of the material

The design of the metal tile roof is composed of 0.35 to 0.7 mm thick steel sheets, which are galvanized on both sides and externally covered with a polymer composition (playsol or polyester). The thicker the sheet, the more robust and stable the roof. Metal tile sheets typically measure one meter in width and one to seven or eight meters in length.


The following are some benefits of metal roofing:

  • small weight (per square meter accounts for no more than 6 kg) due to the maximum possible thinning of the steel sheet: from 0.4 mm to 0.7 mm;
  • resistance to temperature differences;
  • Easy to replace deformed sheets of material;
  • resistance to corrosive exposure;
  • long service life (up to 50 years) and reliability;
  • a relatively small cost of the material;
  • A huge selection of coverage colors (at least 25 different colors and shades).

It is advised to consider material with a thickness of 0.5–0.6 mm when selecting a suitable metal tile. This is because a sheet with a lower weight has a higher likelihood of deforming in the vicinity of the nodes, necessitating replacement. Because an increase in strength also increases the strength indicators of the entire roof pie, the thickness of the metal sheets is a crucial feature. In addition, the weight required to maintain the roof increases with the thickness of the roofing (up to 1 mm), necessitating reinforcement of the rafters.

Basic installation rules

The device for the metal tile roof must be constructed in compliance with the regulations in place, the primary ones of which are outlined below.

The typical metal roof has a minimum inclination of 14 degrees. If the roof is intended to have a gable shape, the lower left corner of the slope is where the sheets are laid first, and each subsequent sheet is positioned on top of the preceding one, accounting for overlap in a single wave. Should the inclination angle be less than 14 degrees—which is not totally accurate—the overlap must already be completed in two waves.

Roof apparatus

When it comes to a tent roof, you should begin the arrangement at the highest point of the structure and work your way down in opposite directions.

The very last metal sheets’ lower edges should stick out from the cornice by at least three to five centimeters. Additionally, boards need to be tied around the edges and at the bottom of the steel sheets.

When installing a metal tile roof, screws with rubberized gaskets are inserted into the lower edge’s sheet waves in steps of 7-9 pieces per square meter.

It is necessary to cover the hobe with compacted extra materials. It is appropriate to use semi-cylindrical details at the upper ends of the profiles because of their shape, which makes them more dependable and securely held on the skate.

You will need an intermediate design first, and then a macing element mounted on the skin using this structure, in order to make the roof yendov.

The roofing system’s inner angle device

Gaps always occur when adding more roof components, which need to be sealed immediately. Use sealing tapes and silicone sealant appropriately for this.

The metal coating in the undercarriage is extremely cold from the inside, and developers frequently observe condensate buildup. Therefore, it is crucial to correctly assemble the metal roof, including layers of material in advance, providing high-quality vapor barrier and ventilation, in order to avoid having to spend money replacing spoiled material.

Necessary tools

Get ready the following tools so that you can use your hands to cover the roof with a metal tile:

The sheet is fastened using self-tapping screws

  1. Drill-shuruvret (mandatory the presence of a nozzle under a self-tapping screw with a hexagonal hat);
  2. A tool for cutting metal sheets (for example, a low -speed disc with teeth of solid alloys, an electric jigsaw, a metal hacksaw or a special nozzle for a drill designed to cut metal);
  3. Measured rail and roulette;
  4. Tracer cord;
  5. A hammer (except for the standard one, you will also need rubber, which is used if necessary to correct the structure of the structure without damaging the protective coating of the metal tile sheet);
  6. A pistol with a silicone sealant;
  7. Marker.

Metal sheets should never be cut with an abrasive circle grinder as this will permanently burn the cut and any surrounding coating.

From corrosion, which will show up in areas where a grinder has been used, to paint or protective film smoothing out flaws in metal tiles. In this instance, it is not possible to avoid replacing the coating.

Features and composition of the roof pie under the warm roof

When building a metal tile roof, having a properly equipped insulation pie is crucial. One cannot rely on the most comfortable operating conditions of the future roof by ignoring its styling because every component of this pie plays a crucial role. As a result, we shall examine each phase in detail. Remember that the roof pie’s layers have a distinct styling sequence that cannot be altered in any way.

The arrangement of layers

Thus, the ingredients of the warm roof pie are as follows:

  • Longitudinal shoulder straps and rafters (this is the roof frame, roofing);
  • Vapor barrier, producing steam from home, but not passing it from the street. The film for vapor barrier is attached from the inside of the crate;
  • Thermal insulation material (for example, mineral wool), laid between the lags of the roof structure (it is necessary to leave a place for ventilation between layers of the pie, because with high humidity the material loses its heat -insulating properties);
  • Contact – layer of pie, the function of which is the fastening of the roofing crate. It is attached parallel to the rafters, pressing a layer of waterproofing material;
  • Chatter -(Bars with a cross section of 50×50, attached along the slope with a step of 30-35 cm.);
  • Waterproofing membrane – is needed in order to prevent the penetration of condensate setting inside the roof. Waterproofing is laid in such a way that there is a free space between it and the insulation, as well as between it and the coating,.
  • Metal tile – creeps directly on the crate.

Airflow within the undercarbon area

Features of the roofing cake under the cold roof

Compared to a warm roof, the roofing pie’s circuit is substantially simpler for a cold roof. The only things included in the pie are waterproofing, metal tile sheets, and a crate.

Rooftop appliance devoid of insulation

The film must first be secured with tiny nails or a construction stapler. Next, the equivalent is placed on top of it, and the waterproofing film is pressed by the screws that fasten it simultaneously.

Similar to a warm roof pie, the waterproofing is fastened with a small indentation (roughly 2-3 cm) from the covering material and the crate. Speaking is designed to allow condensate that builds up beneath the roof to easily flow into the drainage tray. Moisture will rapidly cause the roof to corrode if the waterproofing is attached with a large fit rather than a retreat. A similar crate to that used for a warm roof is laid on top of the waterproofing and counterparty. In this instance, installing a vapor barrier is not necessary.

Due to the lack of noise insulation, as in a warm roof, residential buildings rarely use the technology of a roofing device made of metal tiles without insulation.

Installation of the skate of the roof

Make sure the area beneath the roof has consistent ventilation before installing the ridge bar. In the event that spot ventilation is chosen as a solution, they must be compacted at the edges to prevent deformation.

Setting up the skate

If the horse is round in shape, the fixation is done along the lines of a metal-plastic profile; if it is flat, the strips are mounted in an overlapped pattern.

The skate plank is adjusted to the ridge slope, bent or not bent, as needed, to create the skating nodes of the roof with the triangular and trapezoidal shape slopes.

End nodes

You need an intermediate design and a mockery element mounted on this design in order to properly equip the roof nodes from metal tiles. Endov also needs to be reinforced by adding more floorboards to the crate and fastening them in between the main bars.

Yenddov installation

The yendova planks are installed from the cornice to the skate, with a 0.2–0.4 m overlap. You must form the side on the lower bar at the cornice level. It is necessary to create a seal directly beneath the skate and under the final bar of the Endov.

It will be appropriately trimmed to a distance of 7–10 cm from the axis on both the apple metal bordering one side and the other.

Self-tapping screws hold the endova in place, and if the sheets are removed, they must be fastened to the endova at the locations where the metal overlap of the tanks meets the plane where the valley valves are reinforced:

  • on the bar, retreating from the axis of about 30 cm;
  • on the profile, along the very bottom of the wave, below the stamping of 1.5 centimeters.

Occasionally, special overlays are added to the roofing sheet cuts, overlapping the sheet at least 10 centimeters and laying down from the bottom up. These pads serve a decorative purpose as well as lowering the possibility of blinking snow masses beneath the obliquely overlapped sections of metal. Additionally, it is simpler to slide in the yendova because of overlays and water.

Pipe detour technology

Along with even slopes, other components of the roofing structure include ventilation pipes, channels, and chimneys. This makes the process of overhanging the roof difficult, so you must follow these additional guidelines:

  • First, waterproofing is laid on the sides of the installed object;
  • After that, you need to install a groove on the surface of the slope, which will remove water. It should stand at a distance no further than 0.8 m from the high wall of the pipe;
  • Further, according to the instructions, an additional crate is placed slightly above the passage;
  • The steel sheets of the roof are cut on both sides of the pipe.

Getting around a brick chimney

Only by adhering to the following installation guidelines will the design be dependable:

  • During fixation of the apron with self -tapping screws, the seal will properly use;
  • The nearest peak of the wave of steel sheet should be closed by the apron;
  • Initially, the internal, and only then the external, upper apron, which should be 10 cm, is covered with a metal profile.

Water and snowmelt will unavoidably flow into the apron if it is placed directly in the cut, giving you no chance at all of having a warm, functional roof.

The metal tile roof design is strong and long-lasting, and if you adhere to the installation guidelines for both the metal sheets and the complete roof, your roof will also have outstanding performance qualities.

The advice of experts in metal tile roofing technology will enable you to properly block the private structure with your own hands.

How to install roof nodes from metal tiles?

Every metal tile roof knot needs to be installed correctly, adhering to all guidelines and specifications. This is critical to the overall roofing system’s dependability and integrity. Ultimately, the roof serves as an external component of the entire roof system, intended to shield the house from atmospheric precipitation.

Diagram 1. The ridge node scheme.

Because of this, the material used to make roofing needs to be fairly dependable, long-lasting, and easy to repair in the event that damage occurs. Metal tiles, a modern roofing material, fully satisfy these requirements. Still, all the benefits of a metal roof can be undone by rules breaking and mistakes made when installing the nodes.

Metal tape roof and its design

The profiled steel sheet that makes up the metal tile has a thickness ranging from 0.4 to 0.6 mm, and its surface mimics the tile roof’s surface structure. The leaf is coated in zinc to stop corrosion, and then a layer of polymer that has been painted in various colors is applied on top of the zinc layer. The following are the primary benefits of metal tiles:

Figure 2: Scheme of wind planes.

  1. Corrosion resistance, strength and this is due to a long service life, reaching 50 years.
  2. Small specific weight, which greatly facilitates the process of transportation and installation.
  3. Resistance to temperature extremes and fire safety.
  4. A very attractive and aesthetic appearance that gives the whole house an elegant appearance, which is facilitated by a variety of color shades.

Layers of vapor barrier, insulation, and waterproofing material are placed beneath the roof to provide warmth. Metal roof tiles make up the surface roof. Starting from the lower edge of the roof slope, its sheets are placed on a rafter crate, with a minimum 10-cm overlap required. The roofing assemblies are installed concurrently, or sometimes even earlier. There are various types of structural nodes found on roofs, such as ridge, pediment, wall, apple, and cornice nodes. There are specific guidelines for the installation of every component of the metal tile roof.

The device and installation of the ridge unit

The part of the structure that crosses over the upper horizontal rib of the roof slopes at the intersection is called the skate. Ensuring the subcutaneous space is ventilated is its primary purpose. In a tremendous wind, he also assumes the primary load. There are six known varieties of skates, each specifically made for a particular kind of roof. Nowadays, low-rise construction most frequently uses a semicircular-shaped horse with a standard width or narrowed (rice). 1).

Figure 3 shows where the cornice bar is located.

Last to mount is the horse.

He is installed atop a waterproofing layer or seal and is slightly bent to fit snugly into the sloping roof.

The extreme bar should be two to three centimeters from the edge, and installation should start on the leeward side of the end.

The next strips are positioned with a 10-cm overlap and join along the lines where the stamping is done.

Subsequently, a sealing puck is used to mount the strips, which have a 4.8 mm cross section and an 80 mm length, to the roof sheets in a wave crest at an 80 cm step. Starting from the ends, insert the plugs.

Pediment and its installation

The left and right pediment planks, referred to as the "other winds" (rice. 2), are part of this node. Following the installation of the roofing sheets, they are mounted with a minimum 10-cm overlap, working from the bottom up. If they were previously cut, they must fully enclose the edges of the roof sheets. Waterproofing needs to be brought underneath the pediment bar, which is fastened to the pediment. Such a bar’s primary function is to keep strong wind gusts from destroying the multilayer roofing structure.

There are two planes in which the front-line bar must be fastened. It is fastened to the roofing sheets in the lower portion of each second wave using the same self-tapping screws as the horse. This bar is fastened to the end board with self-tapping screws in a perpendicular plane at a maximum step of 80 cm. Here, the fixed state ought to be higher than the crate all the way up to the roofing wave’s height.

Installation of a cornice node

Cutting scheme (Figure 4).

This node (rice. 3) was designed to shield the edges of the subcutaneous space and the lower portion of the roof from the effects of precipitation, particularly during the winter when blowering snow occurs.

In contrast to the pediment, the cornice is positioned prior to the installation of the roofing, whose sheets ought to be obstructed to allow rainwater to flow straight into the gutter. It is a sheet metal strip bent at a blunt angle along its longitudinal axis, with the same color and design as a metal tank roof.

The cornice bar is fastened to its first board, and a continuous crate is set atop the cornice’s projecting portion. Using a neoprene gasket and the same screws as the metal tile, it is installed with a minimum 10-cm overlap. The overlap is required to stop the section of the cornice bar from vibrating during strong wind gusts. A maximum of 25 cm is used as the step when mounting the self-cutting bar. Installing a comb overhanging the barn’s cornice is a good idea if you want to prevent birds from building their nests beneath the roof.

Design and installation

Endova, which resembles a corner gutter, is an internal docking unit of the roof slopes (Fig. 4). It is made up of two parts: the upper and lower yendova. The upper part is fastened to the crate, while the lower part is placed over the metal tile. Prior to the roof sheets being positioned on a continuous crate, Lower Endova is installed. In this instance, more boards must be positioned underneath it. The installation process is completed in a bottom-up order, with a 20–30 cm overlap. Fighting on its level, the lower element is sliced slightly below the cornice.

It will be necessary to cut the roof sheets to end at the appropriate distance from the yndov’s central axis, which is 6 to 10 cm. A tiny space must be left between the roof sheets and the end, and fixing screws should be positioned no closer than 25 cm from the Endov axis.

There are seals on the valley floors and beneath the upper skate. Protective strips or mosses cover the edges of the cut sheets along the yendovs’ edge.

Junction node and its installation

An independent bar adorns the area where the roofing slopes meet the wall. It has a reverse corner profile that is bent along the longitudinal axis at a dull angle. This kind of bar is installed over a metal tile that overlaps by 10 cm along the roof’s edge. It is fastened to the top of the wave using self-tapping screws and is supported by plastic dowels on the neighboring wall. It is placed with the sealing layer between it and the roofing. Silicone compacts the bar’s adjacent surface to the wall.

You can also arrange the locations of the repair output hatches and chimneys on the roof with the assistance of sections of such a bar. Next, a roofing sealer needs to be applied evenly around the edge of the adjacent area.

The metal tile roof won’t need to be repaired for many years if you follow all the installation guidelines.

Every metal tile roof knot needs to be installed correctly, adhering to all guidelines and specifications. This is critical to the overall roofing system’s dependability and integrity.

Installation of roof nodes from metal tiles

It is crucial to pay attention to the nodes, t. To, when installing a metal tile. The way they are installed determines the roof’s strength, longevity, and tightness.

The quality of each node’s installation determines how reliable the metal roof will be.

The primary metal tile roof nodes are:

Roof nodes installation tools

The following tools must be bought before work can begin:

  • hacksaw;
  • roulette;
  • hammer;
  • pencil;
  • chalk rope for marking;
  • knife;
  • trim for applying adhesive mixture.

The device of cornice nodes

Diagram of Cadet Node Device

Different manufacturers of metal tiles produce cornice strips of different shapes. But in any case, the main principle of installation of the cornice node: in no case do not close the flow of air into a subcutaneous space. The cornice bar can be of different shapes, but it should be installed so that the outer air enters the air blow over the membrane. If you use the roof insulation with two windows, then the air should fall into both ventilation gaps. The condensate flowing through the film must be removed so as not to moisten the wooden roof structures. If the water is installed on the roof, then the cornice bar is installed so that its lower part falls into the gutters of the drainage. All cornice elements are fixed with special roofing nails and are located in a step of about 300 mm, and the overlap of the elements should be at least 100 mm.

Examine the installation and configuration of cornice angles using "Metrotile" and "Roser" as examples of two businesses. Although the two companies use different cornice strips, the basic designs of their devices—after a few minor adjustments—are interchangeable and suitable for a variety of roof types.

Let"s start with the device of the cornice of the company “Roser”, we use the cornice bar of profile No. 1. The upper edge of the headboard of the overhang must be made 40 mm above the rafters. Measure 350 mm from the front on both sides of the slope and drive nails into the obtained marks. Pull the cord between the nails and measure the distance from the front of the frontal board to the cord. This is necessary to make sure that the board is straight and everywhere the distance is 350 mm. The first reshetine is installed exactly on the cord and fixed on the rafter structure. All subsequent reshetins will be installed with a constant step of 370 mm to the ridge.

Selections for roof cornices.

Next, we will tell you how to make the installation of a cornice unit with a cornice bar of profile No. 2 of the company “Roser”. The upper edge of the head of the overhang must be installed at the same level with the upper edge of the counterbruck, which holds the anti -Condocent membrane. From the front of the frontal board, at a distance of 30 mm, you need to install the first sieve and attach it with nails. Next, other layers of solid resets are installed with a step of 370 mm. Under the membrane, you need to mount a dropper for the removal of condensed water. If it is not installed, then the water will moisten wooden roof structures.

Next, think about installing the "Cleo" profile cornice unit from the "Roser" company. The first solid and frontal board are installed, depending on the type of barnized bar that is being used. An anti-bird limiter is fixed to the first lattice and placed atop the bar’s cornice. The final reshetins with 360 mm steps are then put in place.

Next, think about the Metrotile company’s cornice installation. Installing a cornice board, which has a 40 mm thickness, should come first. We affix it to the rafters using nails. After that, we mount brackets on a cornice board for a drain or a condensate droppet. Next, the cornice element is installed, working from the edge of the cornice outward.

End nodes of the roof

Generally speaking, the metal tile yards are the most intricate. This is where the roof’s various surfaces come together. cannot be saved during the approval’s installation; otherwise, there would be no leak insurance for the roof.

Typical end node types include:

  • It begins on the cornice and ends on the skate;
  • starts and ends on a slope.

The apple node is the most intricate nodal component of the metal-based roof.

The apple of the apples, which starts on the cornice and ends on the skate, is where we should start. First, you must confirm that the waterproofing was installed correctly. Leave water grafting along the appliance. There should be no mechanical damage to the waterproofing. The yendov then needs to be strengthened with an extra crate. The sods are where the installed droppers are mounted. Installation is done in a bottom-up manner with a 20–30 cm overlap. After cutting the lower bar to just below the cornice line, selecting is completed. The seal is then mounted along the plank sample and beneath the skate.

After that, metal tile sheets are cut to the edge. Therefore, metal tile sheets should be positioned along the valley’s edge and secured with self-tapping screws.

Less than 25 centimeters from the yendova’s axis, the screws cannot be tightened.

All of the cuts are in line with the base thanks to the rubber kiyanka. We then proceed to install the casual of the yendov. The pad must first be mounted, which requires applying it at least 10 cm up from below. We fasten the valley valves to the top edges of the nearby metal tile. The lining lessens the possibility that snow and rainwater will get between the Endov bar and the metal tile. Water moves along the fold’s axial line beneath the yendov lining.

Endova device architecture.

Consider the rules for the installation of yends that begin on the slope and end on the slope. First you need to check the quality of waterproofing. Next, you need to mount between the boards of the step crate on an additional board. Then a metal tile is brought to the side wall of the auditory window. To do this, you need a sheet of metal tile, adjacent to the side wall of the auditory window, cut so that the cutting line is higher than the output of the yendova by at least 20 cm. Next, you need to make cuts in size of the auditory window. Along the walls of the auditory window on a sheet of metal tiles, you need to mount a universal seal. The cornice bar is installed on the cornice overhang of the auditory window, the valves of the yendovs are mounted. The lower part of the yendova bar is cut along the cornice. The lower sheet of metal tiles can be filled. Sheets of the right and left yends are joined in the upper part. A universal seal is mounted along the selection of the EVOVA.

The installation of metal tile sheets should come next. With at least 20 centimeters of overlap, the sheet is placed over the yendova leaf that has already been mounted. Install all of the sheets that overlap the end. Six to ten centimeters should be the maximum distance between the sheets and the yendov’s axial line. The screws are twisted into regular spots 11–16 mm below the stamping line when the cut sheets are being fastened. Install a loose lining from below, ensuring that it overlaps by at least 10 cm. Mounting the seal between the metal tile sheets and the yendova cashing is not possible.

Roof pediment nodes

Installing the front-line tiles of the tiles is not difficult. Here, the metal tile is installed on the crate, and lining, siding, or wooden boards are used to fill the lower projecting edge of the roof. The end edges of the tile are blocked by the pediment strips, which are put up with the overlap along the cornice pediments.

Installation of ridge nodes

Skating nodes are mounted on attic roofs and on gable roofs. The roof slopes are formed according to the rafter structure, which consists of a crate and rafter legs. A layer of plywood is laid on the crate, which is closed by a steam -permeable lining material. This material provides ventilation, so that there is no decay of wooden structures. Also, for ventilation, you can use a 50×50 mm bars. They fit between the rafters and plywood. Since the riding nodes are susceptible to the maximum effect of precipitation and wind, skate roofing materials have improved strength properties. Such nodes should withstand heavy loads in winter from the resulting ice and have good tightness.

The roof’s ridge knot.

The skate node can be created in the simplest scenario by placing and fastening the skating tiles on the roof’s incline. However, first the bottom protective film needs to be removed. The rib created by the slopes is parallel to the tile installation. Skating tiles are laid directly on the rib to form the ridge, making sure that there is at least a 50 mm overlap with the stacked roofing material.

More effective is the node, which is performed with additional ventilation. Here, roofing material, bars and plywood are not connected at the top point, so there is a need to install the skate frame. It consists of 6 bars 50x50mm. They are located along the entire length of the roof. The first beam is laid along the upper border of the roof, the rest is parallel to it at equal distances. Then, they are filled with a special moisture -resistant plywood and roof sheets, which are connected at the top point. Further, the skate node is closed with a special skate tile. The lowest ends of the frame are closed by a cornice bar.

Washed roof nodes

Where the roof meets the bearing wall is where the roof’s wall node forms. A sealing tape is used to secure a waterproofing film in these areas. It is important to note the ventilation gap between the film and the wall. With a 10 cm overlap, a unique metal profile is used to create the adjacency. After that, the seal is installed between the roofing and the bar.

The effectiveness of the roof node execution will determine how sealed the roof is. A preventive inspection of the roof should be performed, and all overlaps must be observed in addition to the screws being fastened at the proper distance during installation.

The tightness of the roof can be determined by skillfully mounting the nodes. There are various manufacturers of metal tiles that create strips in various shapes.

Examining the complexities of the "Knot of metal" reveals an important roofing component. This small but essential component ensures stability and durability by acting as a connecting point where different roof elements converge. Its design, which is frequently overlooked due to its simplicity, is essential for protecting against the weather.

In practical terms, the "Knot of metal" serves as a pivot, stabilizing the interplay between the roofing components. Its sturdy design is resistant to wind, rain, and snow, which is essential for preserving the roof’s integrity over time. The dependability of this component emphasizes how important it is for roofing projects, both residential and commercial.

Furthermore, the "Knot of metal" is a perfect example of how functionality and style can coexist in roofing solutions. Made from sturdy materials like aluminum or stainless steel, it adds to the roof’s visual appeal in addition to guaranteeing structural resilience. Its adaptability and dependability in creating both functional and aesthetic harmony are valued by both architects and builders.

To sum up, the "Knot of metal" perfectly captures the meticulousness required in roofing craftsmanship. This little element has a significant impact on the overall functionality and appearance of contemporary roofs, both in terms of its decorative value and its role as a connector. Realizing its significance highlights the need for premium components and careful design to guarantee durable and aesthetically pleasing roofing solutions.
