The metal tile is a practical, reliable and affordable roofing. Currently, there are many of its brands. Now the most popular is the metal tile "Monterrey" (installation instructions will be presented below). What is this material? Further in the article we will talk about this coating; installation instructions for the Monterrey metal tile and its analogues will be given.
Main classification
This product has three main options:
- Maxi.
- Standard.
- Super.
The above types are somewhat different from each other. In particular, the profile size and wave step are different.
Main advantages
As mentioned earlier, this roofing is currently very popular. Its affordable price is one of the main advantages. Also, this coating is distinguished by a number of other positive qualities. This material is very resistant to corrosion. In addition, throughout the entire period of operation, it perfectly retains its original color.
Light weight
This advantage is important. A square meter of coating weighs approximately 5 kg. Thanks to this installation work is greatly facilitated. In addition, the entire roofing system will require much lower costs . Installation instructions cover does not provide additional reinforcement.
High speed and ease of work
Many are attracted to the Monterrey metal tile. Installation, the instructions for which are quite simple, is fast enough. A medium-sized roof can be completely covered in a couple of days. This is due to the simplicity of the technology. It is quite possible to equip the roof yourself. Currently, many people use the Monterrey metal tile as a roof covering . The installation instructions for the material are so understandable that they can be laid with their own hands.
Outward appeal
The use of this material provides ample opportunities for design. A wide variety of colors and textures is distinguished by the Monterrey metal tile. Installation instructions are a description of the installation technology. Applying imagination and guided by recommendations, you can realize bold and original design projects. It is also worth noting that this material is safe from the point of view of fire protection and the environment.
Features of the roofing "pie"
It is well known that the roof should effectively protect the interior of the structure from the weather. It is also assumed that its service life will be quite long. In this case, there is a need for proper arrangement of the "pie" before the Monterrey metal tile will be laid. Installation instructions must be followed exactly. "Pie" includes several layers. None of them can be ruled out. Otherwise, the quality of the roof will inevitably deteriorate.
Most often, the "pie" includes the following:
- The outer layer (metal tile "Monterrey").
- Frame (crate on which the material is laid).
- Waterproofing film.
- Design for ventilation (designed for the space between the waterproofing and the crate).
- Inner lining.
- A vapor barrier layer (a film that prevents steam from entering the interior of the house into the insulation layer).
- Thermal insulation.
- Internal counter grill (designed to ventilate the space between the waterproofing film and the insulation layer).
Next, detailed instructions for installing the Monterrey metal tile will be given.
Preparatory work
They need to be taken care of before the Monterrey metal tile is laid. Installation instructions (what are the preparatory work, will be described later) involves careful work with the roof structure. The final result will depend on the quality of preparation. If it is planned to lay metal on the roof during the repair of the roof, then, first of all, the old coating is removed. Then you need to pay attention to checking the correct shape of the ramps. This is also done with new designs during the construction of the house. Next, the width and length of the ramp are measured. In some cases, slight deviations may be detected. Additional elements will help to correct this situation.
Frame
Installation instructions for a Monterrey metal roof indicate the need to equip the supporting structure under the cover. To install the internal counter-lattice, you need bars with a cross section of 50 mm. They cram on rafters. Waterproofing is laid on top of the counter battens. Previously, materials similar to roofing material were used for this. Currently, preference is increasingly given to more modern products. We are talking about waterproofing microperforated films. Their installation is quite free. A slight sag is made. However, the film should not touch the insulation material. The outer counter-lattice is neatly attached from above. The technology is similar to arranging the inner frame. Next, you need to build a crate. This is the construction on which the Monterrey metal tile is laid. For construction, boards treated with an antiseptic should be used.
Necessary calculations
The recommended size of the boards used in the construction of the lathing is 32x100 mm with the condition that the pitch of the rafters will be up to 900 mm. If this value turns out to be larger, then it will be necessary to use boards of a different section. The size of the metal tile should be taken into account when choosing the step of the location of the crate. The distance between the first and second (from the cornice) is up to 300 mm. When placing the rest, the step of the wave of the tile is taken into account. The features of the selected material are also taken into account.
Important information
When installing the end element, certain nuances should be taken into account. The bar must necessarily rise above the lathing plane by a distance equal to the height of the wave profile of the metal tile. The dimensions of this protrusion are 40 mm. In the case of using "Monterrey" type super or standard, the recommended step of the crate - 350 mm, maxi - 400 mm. The most complex roof nodes require the installation of a continuous crate. We are talking about the places where chimneys exit, the formation of internal corners, and so on. In the latter, valleys must be installed. They are prefabricated elements of the roof. Installation is made with an overlap of up to 100 mm. Internal aprons must be mounted where the chimneys exit. For this, abutment strips are used.
Laying Features
This work can be started after the completion of the preparatory phase. Laying is carried out in one or two rows vertically. It depends on the height of the ramp. If there are few joints of the roofing material on the roof, then the coating looks more reliable. Nevertheless, transportation of long sheets and work with them cause a lot of inconvenience.
The main nuances
According to the recommendations of manufacturers, for installation work it is not necessary to use sheets whose length is more than 4 meters. In this case, styling can be done both from right to left, and in reverse order. However, there is also something to consider. If it is a question of laying on the left side, then an overlap of sheets should be formed by placing the next element in the row under the previous one. Installation of the Monterey metal tile in the opposite direction is done differently. The overlap width in both cases will be the same - 150 mm.
Instructions and advice for the installation of metal
The first sheet is laid on the roof. In this case, the protrusion from the cornice should be 50 mm. Due to this, an overhang is formed. Its main task is to prevent the ingress of rain moisture under roofing materials. The sheet must be carefully aligned. It is fixed at the top with a single screw. We need to make sure that it was easy to move. Then you can start laying the next sheet. Do not forget about the overlap width - 150 mm. It must be carefully aligned. Then the sheet is screwed with screws to the previous element. At the same time, it is not fixed to the crate. Laying one or two subsequent sheets is carried out in the same way. Next, you will need to work with the finished block, which consists of 3-4 elements fastened to each other. It should be aligned with the end plates and the cornice. Only then can we begin fixing the sheets on the crate.
Additional Information
Do-it-yourself laying of the Monterrey metal tile is carried out using special self-tapping screws that are equipped with sealing washers from special grades of rubber. The self-tapping screws must be screwed into the deflection points of the wave. For 1 square. m. cover you need eight elements. Also, attention should be paid to bypassing the chimney. According to the information contained in the installation instructions for the Monterrey metal tile, installation of external and internal aprons is required. Manufacturers strongly recommend that you do not ignore these points. The inner apron must be installed before laying the roofing material. To create it, you need to use special abutment bars. Tighter pipe joints require silicone sealant. Installation of the outer apron is done after laying the sheets. For this, elements that are painted in the color of the roofing are used. Connections to vertical walls are arranged in a similar way. Adjoining straps are also used . Recommended overlap is 100 mm. Installation of additional accessories is the final stage of installation. In particular, this applies to roofing ladders, devices for snow retention, the output of antennas and so on. During installation, the protective coating on the sheets must be removed. In the future, this will be very difficult. In some cases, cropping of sheets is required. However, the use of elements with abrasive wheels is prohibited. The fact is that in the process of cutting these materials, heating should be excluded. It destroys the protective coating of the metal tile. In such a situation, it is best to use metal shears for sheet cutting when it comes to the longitudinal direction. For cross-cutting material, the use of a hacksaw or jigsaw is recommended. In order for the metal tile to last as long as possible, the places of the slices are painted over with paint.
