The choice of roofing material is not easy and extremely responsible. After all, every homeowner wants the finished coating to be durable, reliable, easy to maintain and, at the same time, not too expensive. One of the best options today is aluminum roofing.
Such a coating is practically no different in quality from a copper roof, but it is much cheaper.
Aluminum is one of the most common metals widely used in construction and manufacturing. One of the options for using this metal is aluminum roofing.
It must be said that house roof It is a fairly complex and multi-layered structure.It includes elements of thermal insulation, wind protection, protection against the penetration of moisture and steam.
However, the “leading” role in the reliability of the roof being created is played by the roofing material, which is subjected to intense climatic and other external factors.
- Advantages and disadvantages of aluminum roofing
Recently, aluminum-based roofing materials have become very popular. Aluminum has received such distribution due to its undoubted advantages and superiority over other roofing coatings.
- 1.Positive qualities of aluminum roofing
Here are the main advantages of aluminum roofing:
- Diversity of application. Aluminum is a light and sufficiently elastic metal, therefore, with the help of materials based on it, it is possible to cover a variety of roofs, even those that have a complex shape.
- Coating integrity. One of the important advantages of metal roofs is the integrity of the coating. The elements are connected by folding, which eliminates the use of nails, screws and other fasteners.
The use of wide rolls of aluminum-based roofing material to cover the roof allows minimizing the number of joints and increasing the reliability of the coating. - Material quality. The main disadvantage of metal roofs is the tendency of the material to corrode. If roofing aluminum is used, then this disadvantage can be forgotten. Rust cannot occur on aluminum roofing, which is why such roofs last much longer than those made of steel.
- light weight. As already mentioned, aluminum is a light metal, so the roofing material based on it is lightweight. This circumstance facilitates and reduces the cost of installation of the roof.
- High levels of infrared protection. Aluminum is able to reflect direct sunlight, so the roof of this metal helps to prevent excess heat from entering in the summer.
As a result, a more comfortable microclimate is established in the house, and the cost of using air conditioners is reduced.
- Modern aluminum roof - this is a durable coating, since the material has a high degree of resistance to mechanical damage and can last about 70 years.
This strength of the material makes installation easier and simplifies routine roof maintenance work. - Conservationists will love the fact that aluminum-based roofing materials are not only environmentally friendly, but can also be recycled.
- Variety of colors. Today, aluminum-based roofing materials are widely used to paint with the help of paints and varnishes resistant to fading and other external influences.
In addition, polymer coatings based on polyester or polyvinylidene fluoride are widely used to decorate aluminum.
The result is materials that can maintain their attractive appearance for decades. In addition, galvanizing roofing aluminum is gaining popularity, which makes it possible to obtain a material that is similar in quality to expensive zinc-titanium.
1.2 Disadvantages of roofing covered with aluminum
In construction, there are no materials that would differ in ideal parameters. Each of the coatings used has its own disadvantages, which you should know before making a choice.
- Material price. Although aluminum roofing is much cheaper than copper, there are many coatings that are more affordable. However, the rather high cost of materials is offset by its durability, so that the costs incurred will certainly pay off.
- Low level of noise absorption. Coatings made of aluminum, like any other metal, are distinguished by great "musicality" in rain or hail. . A correctly chosen slope of the slopes, as well as the inclusion of a layer of soundproofing material in the roof structure, will help solve the problem.
- The appearance of dents. Aluminum is a rather soft metal, therefore, under mechanical influences of a certain force, dents may appear on the coating, which will spoil the appearance of the roof.
- When painting the roof with unsuitable paints and varnishes, problems associated with cracking and peeling of the paint layer can occur.
2. The main types of aluminum roofing used in modern construction
There are several popular types of aluminum roofing. Among them:
- Seam aluminum roof. This coating is characterized by a high degree of reliability. Unlike seam steel roofing, this option is also acceptable on roofs of complex shape, since aluminum has greater ductility than steel.
- Metal tile "Tegmento" ("Tegmento"). Such a coating is less reliable than a seam roof, but it has an attractive appearance.This roofing option can be recommended for roofs with a slope of at least thirty degrees.
Advice! When using this material for mansard roofs, a combination of coatings is often used. The upper (sloping) part of the roof is covered with a fold, and a metal tile is installed on the front parts, which have a greater slope.
- Metal tile "Prefa" ("Prefa"). This is a material that outwardly resembles natural tiles, but at the same time has the strength characteristics of seam roofs. This effect is achieved due to the fact that during the installation of this type of metal tile, fastening material is not used, the elements are connected by folding.
- Aluminum slate. This type of material is quite popular, as it is easy to install.
- Other types of coatings based on aluminum. Aluminum is a metal that lends itself well to machining, so a fairly large range of coatings is produced on its basis. Among them are such popular ones as "Lemekh", "Shashka", etc.
3. Features of installation of aluminum roofs
Depending on the material chosen, one or another mounting technology is used.
3.1. Aluminum seam roofs
Builders call a seam a connection of metal sheets (pictures). When creating a roof, standing or recumbent folds are used. For the formation of seams, either manual or electromechanical seamers are used.
Mounting Features:
- Before the roofing material is laid, an anti-condensation film must be installed. The purpose of this layer is to keep the metal dry by draining drops of condensate into the drain tray.
- If an aluminum seam roof is mounted, it is recommended to lift the material up one sheet at a time. Sealers must be installed at the installation site.
- It is recommended to use sheets of metal for mounting, which are equal in length to the length of the slope. This will avoid the need to create horizontal folds and increase the reliability of the coating.
Advice! However, the use of sheets with a length of more than 10 meters is not advisable, since the risk of temperature deformations increases when the metal is heated and cooled.
- One edge of the sheet laid in place is strengthened to the crate with the help of clamps (special fasteners).
Advice! The spacing of the clamps should be 600 mm.
- For bending folds, automatic and manual machines are used.
- If it is necessary to use sheets whose length exceeds 10 m, it is necessary to use floating clamps that compensate for temperature changes in the dimensions of the material.
3.2. Installation of aluminum slate
The installation of aluminum slate has much in common with the creation of a seam roof.
- This aluminum roof is mounted without screwing screws into the material, the connections are made by folding.
- Aluminum slate can be mounted on both solid and sparse lathing with a lath spacing of no more than 25 cm.
- For fastening aluminum slate sheets, clamps are used, which are arranged in increments of 30-40 cm and attached to the crate using self-tapping screws.
Advice! When attaching the clamps to the lathing laths, make sure that the self-tapping screw or nail enters the lath strictly at an angle of 90 degrees.
When installing aluminum metal tiles, you should follow the recommendations given by the manufacturer.
4.Conclusions:
Thus, aluminum roofing is a reliable, durable and practical coating. And the relatively high price of the material is offset by its durability and unpretentiousness in maintenance.
