The technology of laying metal tiles on the roof

Metal tiles are becoming more and more popular as roofing materials because of their strength, visual appeal, and simplicity of installation. By fusing contemporary engineering with useful application, metal tile roofing technology provides homeowners with a dependable way to shield their houses from the weather. Metal roofing tiles, in contrast to conventional roofing materials, are strong and lightweight, making them appropriate for a variety of architectural styles and climates.

Careful planning and preparation are the first steps in the installation of metal tiles. The first thing roofers do is make sure the roof structure is sturdy enough to hold the weight of the tiles. In order to ensure longevity and safety, this frequently entails examining and strengthening the underlying framework. When the base is prepared, an underlayment or weatherproof membrane is added to form a barrier that keeps out moisture and leaks.

The ease of installation of metal tiles is one of their main benefits. Roofers usually start at the eaves and work their way up to the ridge, carefully fastening each tile to guarantee a precise fit and correct alignment. It is common to find interlocking panels or tiles, which not only makes installation easier but also improves the roof’s resistance to water intrusion and wind uplift.

The aesthetic appeal of metal tiles has been enhanced by contemporary manufacturing processes, which provide a broad selection of colors, textures, and profiles to match any architectural style. While enjoying the greater durability and minimal maintenance of metal roofing, homeowners can select from options that resemble more conventional roofing materials like slate or clay tiles.

In summary, the technology used to install metal roof tiles combines creativity and usefulness. It offers homeowners a resilient, aesthetically pleasing roofing option that increases the curb appeal and value of their homes while withstanding the weather.

Metal Tiles Technology of Laying
Lightweight Metal tiles are lightweight, making them easier to handle and install compared to traditional roofing materials.
Weatherproof They provide excellent weather resistance, protecting homes from rain, wind, and snow.
Installation Process The process involves preparing the roof surface, laying down underlayment for moisture protection, and then carefully placing and securing each metal tile.
Tools Needed Basic tools like measuring tape, screwdrivers, and a metal cutter are typically used during installation.

Roofing system installation tools

Prior to beginning work, the following tools must be ready: hammer, long rails, roulette, mounting knife, marker, screwdriver with screw nozzle, cord, self-tapping screws, and tools for cutting roofing materials.

The electric jigsaw, the hand-held lever scissors (left, right, and straight), the knife for cutting off small pieces of metal, and the electric scissors (cutting down) are the instruments used to cut the roof.

The sections of the profile need to be painted using a specific paint spray can after it has been cut. Zinc will be shielded from further corrosion as a result.

It is forbidden to use an abrasive circle or grinder to cut roofing material! Such cutting compromises the zinc itself as well as the polymer coating, which will cause additional oxidation and corrosion.

Calculation of the required number of materials

It is necessary to measure the roof, account for all protrusions and elements, and determine the number of rows that will be on the future structure in order to determine the amount of material required for laying the metal tile. This is accomplished by using a straightforward instruction that makes calculating the quantity of material simple.

For instance, the roof slope’s width is six meters. Additionally, the profile’s useful width—also known as its effective length—is 1.11 meters, as stated by the profile’s manufacturer. (6/1.11) = 5.40 will be the number of rows; rounding to the nearest whole number yields 5 rows.

The length of the roof slope from the cornice to the skate, plus the overhang, which is between 40 and 50 mm, plus 150 mm (if multiple rows are being used), which are minimal with horizontal overlap, are measured to determine the length of the sheets and their quantity.

For instance, the length of the measured roof slope is 7 meters. In that case, the necessary length is 7 + 0.05 + 0.15 = 7.2 meters (assuming two sheets are laid side by side).

The majority of metal tile producers let customers select the length of the profile cutting. The maximum length is eight meters, but using sheets that are no longer than four to five meters is most practical, according to experience. As a result, two rows of metal tiles were installed in the aforementioned examples.

What you need to know when using a roof profile

Prior to installing metal tiles, you should be aware that following a few easy guidelines will guarantee the materials’ long-lasting performance.

  • To transport the profile by car, it is necessary that the body length is larger or equal to the length of the profile sheet;
  • overalls can consist of a conventional construction overalls, gloves and soft shoes (rubber sneakers are quite suitable) so as not to damage the profile material. When working on the roof, it becomes only on the doom and in the deflection of the wave;
  • With manual transportation, it is necessary to carry the sheets in an upright position so that distortions do not occur that may lead to further deformation of the material;
  • For storage of the metal tile profile, bars of 200 mm thick with a step of 500 mm are used. If the shelf life of the profile exceeds one month, then it is necessary to unpack the sheets from the factory packaging and shift with rails, taking into account the maximum height of 70 cm, the stacks received;

  • It is necessary to make a control measurement of the roof. After the rafters are installed, the rectangularity of the slopes is measured. The difference in the two diagonals of the roof should not exceed two centimeters, and all installed rafters should be located in the same plane;
  • Check the minimum slope angle of slopes, which is at least 14 °.

Selection and installation of self -tapping screws

The profile is secured to the crate using galvanized screws. Because the service life of high-quality fasteners is commensurate with the service life of the metal tile (30-50 years), the quality of self-tapping screws must be treated seriously.

Select unique, proprietary screws with the required color and gasket made of EPDM (ethylene-propylene-dien-monomer) rubber to accomplish this.

Using an electric drill or screwdriver with a speed and reverse switch, they are fastened. If the material layer sustains haphazard damage during the laying process, the damaged area needs to be covered with a masking aerosol applied with a cane.

The screws should be sufficiently tightened, but not so tight that the sealing gasket is forced.

Rules for fastening metal tiles

All structural components need to be treated with an antiseptic agent before installation can begin. The rise to the roof along one sheet is where the technology of metal tile laying and fastening starts. Special lifting belts or lags are used, which run from the ground to the edge of the roof, depending on the building’s height.

The first sheet of metal tile is leveled along the roof’s end and cornice, with the length of the sheets matching the slope. Roofing screws with colored heads and EPDM gaskets are used to fasten profiles. The dimensions are 4.8 x 28 mm for a wooden crate and 4.8 x 20 mm for a metal crate. The length of self-tapping screws that are ultimately needed is determined by the type of profile and is provided by the metal tile supplier.

The screws are inserted through one wave in a checkerboard pattern in the sole of the wave at the fitting locations to the crate. Six to eight screws are used approximately every square meter of profile.

The edge of the second sheet is positioned beneath the edge of the first and aligned if the metal tile is laid from the left to the right. Lay the second sheet first to the first if you are going from right to left. The placement of subsequent profiles must resemble the preceding one.

The first sheet is placed on a crate that has been removed 40–50 mm above the cornice’s edge. It is fastened to the crate at the cornice with a self-tapping screw and to the skate’s edge with a single temporary self-tapping screw.

The second profile sheet is then put in place. In order to achieve this, the sheets must be precisely and firmly joined to one another with a lateral longitudinal overlap to prevent gaps and distortions. Self-tapping screws, measuring 4.8 × 20 mm, are used to connect them, passing through the top of the wave and beneath the profile’s transverse wave. From the cornice to the skate, the connection begins.

Three or four metal tile sheets are joined in this manner. The block of profiles is aligned with respect to the cornice once a temporary self-tapping screw that was put on the first sheet close to the skate is unscrewed.

On both sides of the block, control measurements of the removal are made. The sheet is clearly correctly aligned if the dimensions match, and it only needs to be screwed evenly to the crate with one self-tapping screw. The remaining sheets are fastened to the crate and at the joints.

Following installation, a soft brush must be used to remove the shavings from the drilling and circumcision, and the damage must be tinted with special paint.

When a roof slope consists of multiple rows, it is necessary to appropriately apply a different principle to the roof profile. The way the sheets are extended in this instance is depicted in the figure below. The drainage grooves on the longitudinal edges of the connected metal tiles dictate the installation process. When constructing metal tile sheets, the longitudinal wave’s sole is fastened to the crate and the sheets are joined along the roof slope using a drill bit that is at least 150 mm in diameter.

Without attaching the metal tile to the crate, the transverse profile of the tile is fixed at the end of the transverse wave or into the sole of the longitudinal wave above the transverse wave. Four self-tapping screws are needed for this procedure. 8 x 20 mm (metal case).

Installing a dwarf (tent) roof follows the above-discussed principles: start at the top and work your way evenly down both sides.

The previous layered sheet should be blocking each profile’s capillary groove.

We examine the contemporary methods used to install metal tiles on roofs in "All about the roof." This article explores the technology that makes metal roofing tiles aesthetically pleasing and long-lasting. We emphasize how these tiles are made for both practicality and visual appeal, from the benefits they provide homeowners to the detailed method of installing the tiles. This guide gives you a concise rundown of the steps involved in building a safe and fashionable metal-tiled roof, regardless of whether you’re thinking about upgrading your roof or are just interested in roofing technologies."

Fastening of the skate

The attic space must be ventilated in order to prevent the profile sheets from converging under the skating bar. At the peak of every second wave, self-tapping screws hold the horse fastened to the roofing. The overlaps between the planks are concurrently at least 10 cm long. A semicircular skate is installed on a hut roof with tent plugs and Y-shaped linings.

Installation of cornice bar

The frontal board is shielded from atmospheric precipitation and additional damage by the cornice bar. Placks with 300 mm p and 50 mm overwhelming are nailed with galvanized nails.

Installation of yendova

The yendov grounds are set up at the same level as the crate. To guarantee ventilation, there must be a 20 mm space between each valley valve. On the corners of the valleys, the cornice bar is mounted after being cut.

Subsequently, the lower yendova profile is fitted and severed in the pattern of the cornice strip. In the same way that profile sheet boundaries are invisible, draw guides along the Endov plank. A minimum of 200 mm should be left between each guide’s line.

Following roof installation, the decorative upper lining was installed for aesthetic beauty along the entire length of the yendova bar. It is fastened with a step of 300–500 mm in the upper bend of the metal tile’s wave.

Installation of the end bar

Installing the end bar on the end board involves using self-tapping screws at a 1000 mm step to secure it. The bar is fastened to the crate at a distance of 400–800 mm using self-tapping screws that are inserted through the top of the roof sheets. It is imperative that the end bar overlap the wave’s upper crest upon completion of installation.

The technology for installing the skate bar and seal

The ridge bar is directly installed after the universal seal has been fixed. In order to install it, the protective film must be removed, and it must be positioned 25 mm away from the ridge’s edge and toward the center. Self-tapping screws are used to fasten the ridge to the roof sheet in every third longitudinal wave, with a minimum overlap of 100 mm allowed.

Because of their unique combination of strength, style, and ease of installation, metal roofing tiles have completely changed the roofing industry. Their popularity is a result of their exceptional weather resistance and longevity, combined with their ability to replicate the timeless appearance of traditional roofing materials like clay or slate.

The secret to successfully installing metal tiles is preparation. A uniform and secure installation depends on the roof deck being smooth and clear of debris. The lifespan of the roof is further extended by using the proper underlayment, which also improves waterproofing and thermal efficiency.

One of the most notable benefits of metal tiles is their low weight, which makes installation easier and lessens the building’s structural stress. This feature facilitates simple fitting and alignment, which speeds up and improves the efficiency of the installation process. It is combined with their interlocking design.

Additionally, metal tiles can be customized to fit a variety of architectural styles and preferences due to their versatility. Because they come in so many different colors, profiles, and finishes, homeowners can design the exact look they want for their homes.

In summary, the technology used to install metal roof tiles combines aesthetic appeal with functionality. Metal tiles offer an appealing alternative for both contemporary building and renovation projects, whether you’re looking to improve the curb appeal of your house or are searching for a roofing solution that blends durability with simplicity of installation.
