Metal andalusia

In recent years, profiled metal has been used as a roofing material. Metal tile or professional sheet of different colors and shades, can decorate the roofs of residential, industrial and civil buildings. This material has become popular due to easy and quick installation, and the reasonable price for this material makes it special. Every year there are new types of metal tiles - one of them is Andalusia, which is characterized by a hidden method of fastening. In this article we will look at the technical characteristics of the Andalusian metal tile and its installation features.

The advantages of metal tiles

Among the differences between Andalusia and other types of metal tiles, the method of attachment to the crate and between themselves should be highlighted. The result is an improved appearance. Fastening occurs at the expense of the Z-shaped lock. In addition, each sheet is equipped with a hole for the screw, and the place of attachment is closed with the next sheet during installation.

The advantages of metal tiles Андалузия:

• The metal tile Andalusia after installation forms a hermetic structure, which does not have through fastenings.
• The tiles are smaller, so it’s easier to work with and easier to transport.
• A simple mounting system allows installation to the non-professional.
• No need to buy screws for the color of the roof covering.
• The deep profile of the sheets provides greater aesthetics and durability of the roof.
• Similar in appearance with natural tile.
• The manufacturer declared a warranty period of thirty years.

For objectivity, mention should be made of the shortcomings of this roofing material. It has a great price, and installation can be difficult for those craftsmen who are used to working with other types of coating. Moreover, there is a danger of incorrect marking of the roof, so it will not be possible to whip up metal roofing.

Profile Views Andalusia

Today, there are several types of Andalusian roofing:

• One-step.
• Two-step.

These two species differ in the size of the sheets and the height of the profile. Thus, the profile height is 7 cm, the wave step is 4 cm, and the sheet thickness is 0.5 mm.

• Metal tile under the order. In this case, the sheets will not have hidden locks, since the fastening will be done by an open method.

Metal tile coating

Special attention should be paid to cover sheets. It is glossy or matte. It is made of pural, polyester and other materials. You can choose a shade from a palette of forty colors, some of which are quite exotic.

Sheets are made of galvanized steel, which is covered with several layers of primer and polymers. This prevents corrosion, protects against moisture, UV rays and other possible effects.

Preparation for installation

Before installing Andalusia, you must check the roof diagonally and for tightness. If a small discrepancy is found, it can be leveled by using additional elements. Additional support boards, valleys and other safety features must be installed around the pipes. Also fixed bottom plate endy. If you plan to install gutters after roofing, you should fix the gutter hooks, the ledge bar and the gutter itself.

Using metal Andalusia, it is recommended to make the roof slope from 25 ° to 30 °. If you install with a smaller slope, the metal will have a less pronounced appearance.

Note! As a rule, sheet trimming is carried out directly at the installation site. Therefore, for cutting, you can use electric or manual shears for metal. If possible, you can use a circular saw or jigsaw.

Cutting sheets with an abrasive wheel is unacceptable, as it can damage the polymer coating, and edge corrosion will form at the ends after cutting. The resulting chips after cutting must be gently swept away. If you can not do without scratches, they can be painted over.

Features of mounting crates

It is important to follow the installation instructions for metal Andalusia. In the manufacture of crates should consider some tips and recommendations:

• The installation of rafters is carried out in steps of 600–700 mm Then the vapor barrier and sound insulation are made. Its fastening is carried out by the bars of a contra-lattice.
• For rafters, a bar of 5–15 cm is needed, for a batten - 3 × 10 cm, for a counter grille - 3 × 5 cm.
• Depending on the profile, the crate step is selected. We should not forget that the bottom board of the batten should be 15 cm wide, since the gutter will be fastened to it.
• The very first board of the batten will be 2 cm thicker than all the other boards. This is due to the fact that the first wave of the sheet will fit below it.
• If the bottom row fits on a special bar, then the first board is of normal thickness.
• The overhang of the roof should be 40–50 centimeters, so the initial strips are mounted with this calculation.

Mounting sheets

If the roof has horizontal sheets, then fitting parallel to the eaves is not necessary. If the ramp is rectangular, then you can start fixing sheets from either side of the roof. To do this, pull the cord on the ridge, which will be the main guideline when laying the sheets. Secure the first sheet in a special hole, it is in the upper left corner. Secure the next five sheets with a temporary mount using self-tapping screws.

Note! For best results, start laying each row from the middle of the ramp. So less likely that vertical and horizontal shift sheets will occur.

The process of mounting sheet metal is performed in the following sequence:

• The profile is fastened to the crate. The edge of the sheet is covered with the edge of the next, as a result, all attachment points will be hidden.
• After laying the first sheet temporary fixings need to be removed. The installation of the second, third and subsequent rows is carried out in the same manner.

This method of roofing of metal Andalusia is possible only on rectangular roofs. Installation on complex roofs is carried out by other technologies.

Finishing work - making gable

At the end of the roof is mounted wind strip. It will protect the profile from the wind, as well as serve as a decorative part. These strips are fixed with self-tapping screws 4.8 × 35 mm in 80 cm increments into the upper crest of the wave. With the butt in 70 cm steps. The overlap of the plank should be 10 cm.

General tips and tricks

It is not recommended to cut the tile sheets of the grinder, as this can cause negative consequences. Damage to the polymer coating, and also appears the likelihood of corrosion. As for the subsequent care, it is in the careful removal of construction debris. To do this, you can use a hose with water or a soft bristled brush. Every spring, it is necessary to clean the gutters from foliage and other contaminants, as well as to carry out a visual inspection of the roof. Thus you prevent the destruction of the roof and save money on repairs.
