Installation of Monterrey metal tiles + step-by-step instructions
It is not difficult to work in metal roofing tiles. In order to create a roof that is both durable and effective, it is enough to purchase high quality materials, and the essence of the work helps to master the step-by-step instructions for installing Monterrey metal tiles.
Features of Monterrey metal roof tiles. As a rule, experienced craftsmen assure that in order to correctly lay the profiled roofing, it is enough to align and correctly attach the metal tiles, and other operations are almost no different from the installation work of a simple sheet profiled roof type.
In reality, things are not so easy.
In fact, Monterrey metal shingles have certain features.
- Wave type profile is ideal for roofing. Monterrey waves made of galvanized thin steel are more stable and stiff.
- Monterrey roofs require special attention to the quality of the battens. If in the food direction the stiffness of the sheet is quite enough, then the waves across the material will be very weak, and therefore it is not worth saving on the counter-lattice.
- There are several types of profile with different step and wave size. The difference in parameters primarily affects the cost of the coating and preparation for installation.
- The durability and quality of the material depends on the manufacturer of the Monterrey metal roof tiles.
Please note that the RANNILA STEEL plant created and launched a very original and beautiful profile in production. For a long time, metal tiles of this type were produced in Finland and have long become the standard of quality.
At the moment, dozens of foreign and Russian companies make metal coating with a branded profile. The original profile is most often forged, unlike other models. In the Russian Federation, you can find Monterrey, which is produced in Voronezh, in the vastness of China or in the Siberian outback. The roof covering is stamped on the most modern equipment made of metal, which is made in Russia. For this reason, it should not be surprising that the assemblies for the Monterrey metal tiles purchased in various places may simply not fit the roofing, and the future installation of the coating can become hellish torture.
Another difference is the specific surface pattern is perfect for building roofs of any design and style. Art Nouveau and modern techno styles have become an exception to the rule; for such roofs, experts advise a more modern "chocolate" Cascade. Most designers, not without reason, say that the metal tiles Cascade and Monterrey are antipodes, but they are identical in quality and durability.
The presence on the construction market of many copies of a real product of Finnish origin and generics often confuses customers ..
. For example, it is quite possible to purchase metal tiles with a sheet thickness of 0.03 cm with an authentic profile and a distinctive polymer-type velvet coating.
The thickness of the improved material of the Monterrey metal tile is 0.04 cm, which is 20% less than the standard.
It is believed that this is an economy class material, despite the fact that the Finnish classic roof covering has a metal thickness of 0.05 cm, without corrections for geometry and secondary parameters. The installation of a lightweight roof will be seriously complicated, and therefore the manufacturer produces shorter type sheets. Due to the small thickness, the sheet will bend strongly, as a result of which the installation of the lathing for metal tiles will need to be made denser, with a smaller step. In addition, due to the smaller dimensions of the sheets, the number of joints increases.
It is impossible to reduce the length of metal shingles overlaps for certain reasons, as otherwise the roof would be terrible to hold water. As a result, the consumption of roofing material for covering a roof of a uniform size will increase by 20% compared to installing a Finnish metal roof. The installation scheme of the Monterrey metal tile is special, and an example of a lightweight type of roofing can be the type of Monterrey Lux tile. Its main parameters are as follows:
4 cm, the excess of one step over the leaf, the next one is 1.5 cm.
Moreover, Lux is considered a very high-quality roofing coating and is used for small buildings with a pitched length of up to 6 meters, and such metal tiles are also made from Russian metal and from foreign raw materials. When buying a generic metal tile, you need to know 100% in which country the steel sheet is produced. The best is Belgian or Swedish steel, it is usually imported to create domestic luxury and premium finishes. The worst steel is from China and Southeast Asia. Monterrey from RF metal takes an intermediate position.
Moreover, you can find offers of Supermonterrey shingles, and its only difference from the simple one will be the profile, which is slightly higher. He has an average ridge height of 2.5 cm, and the excess of rows is 2.1 cm.
Finnish original tile
For comparison, we present the parameters of the classical model Standard:
- Height of the ridge in wave 3.
9 cm, step / period 3.5 cm.
- Metal thickness 0.05 cm.
- Full and useful clearance in width is 1.
1 meters and 1. 18 meters.
- The weight of each square is 4.65 kg, with 0.275 kg for the zinc protection.
It turns out that with a high profile, with a greater thickness of zinc and the main metal, the Finnish Monterrey is only 0. 15 kg heavier than the metal tile Lux. This means that the generic has a much thinner zinc layer and protective coating, and is worse in density than the original product.
The usual size in the width of the sheet is 1.1 and 1.
18 meters. The first dimension is the working width, and the second is the total edge-to-edge distance, it is used for planning transportation. The difference in dimensions appears due to the presence of a thin groove from the capillaries on the left edge. The working width of a metal tile is obtained by installing and overlapping the vertical edge. The sheet length can be from 0.
5 to 8 meters, in practice, they try to cut the material even before being shipped to transport, very long canvases are very inconvenient to transport, rise to the roof and install on the crate. There are restrictions on the dimensions of metal roof tiles for the top sheet. As a rule, the roof slope is sewn up with two rows of coating, and for the sheets on the top row, the manufacturers have compiled a table of prohibitions. The selected sheet length of Monterrey material with a wave step of 0. 35 meters should not fall within the specified size range.
For example, with a slope length of 8.2 meters, the length of the material will turn out to be 4.1 meters, and this is not included in the prohibition range, in which case it is 4.23-4. 33 meters.
The preparatory stage begins with the choice of the installation method for the counter battens, as well as the order of laying the sheet on the roof. Installation is no more difficult than for any other material.
How to make counter-lattice
The assembled building frame should be checked for sharp beams and chips, protruding heads and ends of nails. All this needs to be cut, hammered and sanded to a smooth state. A new stage will be the stretching of the steam waterproofing sheet onto the rafters, it needs to be pulled with a small sag and fixed along the pitched perimeter.
Next, the slats of the control lathing are sewn onto the rafters.
Good advice! So that there is no rupture of the vapor insulation in the places where the lathing is installed, it is necessary to pre-stick the adhesive double-sided tape on the canvas.
The slats of the control lathing for Monterrey are stuffed onto the rafters, not reaching 0.2 meters to the ridge beam, this is required for the future arrangement of the ventilation gap.
Manufacturing lathing for Monterrey
After creating a counter-lathing, it is necessary to consider the installation diagram of the lathing for Monterrey metal tiles.
Usually an inch board with a width of 10 cm is used to create. In this case, on a 10 cm board, the lathing step for metal tiles is 0.35 meters. The first rail needs to be nailed on the cornice at 3.5-4 cm, and the rest must be laid with a step that is equal to the vertical wave period.
If the installed rafters are wide, 0.9-1 meters, then it is better to use a 15 cm board, and the step of the lathing under the metal tiles in this case is increased by 1.5 times.
The most successful type of stacking of sheets is shown in the figure below. Installation on the side planes starts from the gable strip for gable roofs or the line of intersection with the adjacent slope for the hip.
The hip planes begin to spread from the middle of the slope.
What is the overlap of metal tiles
The minimum size of the overlap of two edges in the transverse "wave-wave" direction must be at least 8 cm. The overlap of a pair of Monterrey sheets in the longitudinal direction is chosen equal to the length of the support edge. The recommended size is 13 cm, and for a profile with a step of 0.4 meters, the overlap increases to 15 cm.
Features of laying the material
Up to to start work, it is required to pull two marking cords, one along the eaves strip, and the second along the line of placing the upper edge on the bottom row. When planning the laying level of the first row of metal tiles, it is necessary to take into account the additional overhang of the lower edge above the eaves board. Gently lift the first sheet onto the crate and carefully align with the marking cords and the bubble level. The canvas needs to be fixed with one self-tapping screw in the upper part so that it is possible (if required) to adjust the position relative to the horizontal. The second sheet is laid with an overlap in one row, the third is required to start the second row, and the installation of the fourth is performed near the second.
For correct installation, the following 3 conditions must be met:
- Self-tapping screws must be screwed in neatly perpendicular to the surface of the metal tile, any distortion will lead to the fact that the polymer coating will be damaged.
- Metal shingles are staggered, each sheet needs to be pulled to a wooden base with a small gap.
- Fastening to each sheet is carried out along the cornice, pediments, at the overlap.
The mount should only be installed with silicone washers in the profile recess. The criterion for the correct screwing of the self-tapping screw will be the deformation degree of the gasket, because the tiles should not "pop", and the washer remains slightly pressed against the canvas.
It is sometimes believed that due to the good geometry of the surface, the installation of the Monterrey metal tile can be done on a relatively weak lathing. Certain craftsmen manage to lay horizontal bars only along the overlap line of a number of materials. This is wrong, because such material, unlike ondulin or polycarbonate slate, has high longitudinal rigidity, and therefore, with a strong wind gust, the sheets begin to flap and swing the mount.For this reason, the roof covering must be tightly pressed against the battens, under each canvas there must be no less than 3 horizontal bars of beams.
Step-by-step instructions for installing metal shingles help you understand the basics for roofing.
This is enough to cover a small gable-type roof for a bath or a shed; for more serious objects, the installation must be carried out together with an experienced specialist.
