When a person plans to build his own house, it is important for him to choose high-quality material. In addition, everyone wants to save. Many people want to choose the most reliable and at the same time cheap material. Roofing professional sheet can be considered just such a building component. Often you can encounter a problem such as a lack of information about a particular model. Not every seller shows his best side.
So that nothing like this happens, you need to stock up on information before starting a choice. This will help to make the right choice and create the conditions for a quality building for many years.
Roofing sheet
Profiled metal sheets have become actively used in any construction. This is a choice not only of professional masters, but also of beginners. This component is suitable for roofing, although today it is used in other areas. Each building material has its own characteristics, it is they who confuse the inexperienced craftsman. But basically it is worth paying attention to the thickness and quality of the roofing sheet.
Before buying, you should understand these indicators in order to accurately choose the right one. After all, the manufacturer guarantees quality only with proper use. On the market there is a whole assortment used for its intended purpose:
- For walls of outbuildings.
- Canopies.
- Fences.
- The ceilings.
- For the roof.
It is clear that the main thing is to choose the right roofing sheet. Because he has many serious tasks. In addition, it is exposed to all natural phenomena, and the roof over your head should be reliable.
How to make a choice?
Before buying, you should understand what we are dealing with. This is a profiled metal sheet with many hard ribs. Due to them, a high level of strength and immunity to physical impact is acquired, as well as resistance to wind and other adverse weather conditions. To create a roll of steel is used. On special devices, separate sheets are made. Their configuration affects the overall strength.
In addition, additional processing is used in the production. She makes indicators even better. You can compare the roofing sheet with a cake in several layers:
- A sheet of steel is the basis.
- Then comes the zinc coating on both sides.
- Further, compositions that resist corrosion are used. Application is carried out around the perimeter.
- Another component that allows you to create maximum protection is the primer.
Today, a galvanized roofing sheet can have a different color scheme. It is clear that at the production level special paints are used. This is a unique creation system, after which the original design of building material is obtained. It is under such a coating that the house will be in full protection. But there are other types on the market:
- Steel sheet. It is produced without any additional treatments.
- Aluminum or copper. According to the characteristics, this material is similar to the previous one.
- Roofing in several variations - perforated, rolled, bent under various textures.
- Galvanized roofing sheet, but without additional coating. Its cost is lower, but the service life is small. It is rarely seen on the roof. It is used more often for outbuildings.
All of the listed roofing profiled sheets have different thicknesses . In addition, construction masters recommend that when buying, pay attention to the fact that the full width has differences from the useful one. There are such types of elements:
- Carrier.
- Facade.
- Wall.
- Ceiling.
- Shuttering.
When buying a lot of questions. It is necessary to determine in advance which type is suitable. Only in this way the purchase will be carried out correctly and it will become easy to cover the roof.
What should not be forgotten when choosing?
There are three simple directions that will help make the choice right and error-free:
- When buying, pay attention to the thickness and level of additional coating (to create an ideal roof, the bearing and the wall are suitable). Moreover, in the first there is an additional recess, which gives its advantages. As a result, when the roof is covered with an overlap, a good groove is formed under the water. The start will be at the ridge, and then to the gutter. But the wall does not have such a feature.
- When a professional sheet with a capillary groove is selected, then the store should find out if it bends. Because some manufacturers do not fulfill it reliable, and when it bends, its main purpose (protection) is lost.
- To cover the facade of the building, fixing the roofing profiled sheet - this is quite appropriate. But in the reverse order you should not do this. From this it is easy to conclude that the facade corrugated board is not suitable for the roof.
These are important features. They are taken into account when choosing. Having such data in the store, you can not ask unnecessary questions to the seller, but choose clearly according to the given parameters.
Grades of building material
It can be noted that the characteristics of the profiled roofing are different. There is a huge range of brands. If a person works in the construction field, then he knows where to read the necessary information and make a choice. Often found on sale:
- S-21. According to the masters, this is the best model of professional sheets for creating high-quality roofing. But before that, you need to create a suitable crate so that the step does not exceed 0.7 meters.
- NS-35 is a roofing sheet, the characteristics of which are the highest (wave height - 35 mm). It is also often used as a fence.
- NS-44. It is used to create a strong roof, because there are additional stiffeners.
- RN-20. This is a unique material because it fits in any direction. He made a groove for drainage, and the area of work is more than 1 meter.
What do these letters mean?
C and H is the beginning of the names (wall and bearing), but the second model is suitable for the roof. The numbers make it clear the size of the length and wave. But when choosing it is better to give preference to those companies that conduct production according to GOST, since the technical conditions no longer give high quality. It is always worth the seller to be interested in having a certificate.
Types of building material
When choosing, you need to pay attention to the main indicators: cost, type, external data, the angle of the roof. Price indicator is everyone’s business. There is not much to talk about it, because the finish budget is calculated individually. But the rest must be taken into account. If the quality is too low, then it is worth considering what the manufacturer saved. But mainly this indicator is affected by the additional coating and thickness.
Sometimes there is such a feature that the same material at different points of sale has unequal parameters in price. Therefore, before making the final purchase, it is better to find out all the nuances and features. It is clear that bypassing intermediaries is an opportunity to save money. In addition, those who produce, work on an individual order and perform cutting sheets of the desired length. If you communicate with the masters, then they help not only to correctly calculate the required amount for the roof, but also to suggest what components will be required during the installation of the roofing profiled sheet.
Coating
The coating of the material itself may be different (as well as the thickness of its application). It is good to use bright colors for the roof, since there is an additional application on them - this is plastisol. Polyester is chosen by those for whom external indicators are important. But the material is not so effective when exposed from the outside. The best option is plastisol, since it practically does not fade, is resistant to damage. But its price will be higher than the usual option.
The polymer used in the coating based on polyurethane, withstands all negative precipitation. As a result, the structure will be protected as much as possible in any weather. Any corrugated board should have a protective layer of zinc, but the thickness is already different - from 0.5 mm. It is clear that if this indicator increases, then the corrosion resistance will be better. It is the external indicator that is important for designers, but the masters of construction say that the look also affects quality.
Inspection
Few people focus on a thorough examination of the roofing profiled sheet. This is a mistake, because then it will be too late to prove that it was acquired a marriage. To cover the roof served a long period of time, you must completely eliminate such misunderstandings:
- Uneven paint.
- Transitions in the color scheme when the material is unevenly coated.
- The presence of chips or small cracks.
- The strength of the coat of paintwork (it crumbles or not).
At the same time, the sheets themselves must be smooth, including the edges. With slight bending, the material should return to its original position immediately. Such a sheet will never break if the quality is high. Some believe that the angle of the roof is of great importance. In the presence of precipitation, a load distribution occurs, which affects the service life of the entire structure. Therefore, even at the planning stage, appropriate material is selected.
These are the simplest recommendations that will help you to easily select the required material. Only such a roof will be a reliable protection for all residents. And the owner will not spend money in vain. For the design to last for many years, do not forget about the correct installation.
Installation work
The weight of the roofing profiled sheet is different (from 4.7 to 6.43 kg / m 2 ), therefore, when carrying out work, this fact must be taken into account. It is not always possible to handle one person. Today, several styling methods can be noted. The procedure itself is too extensive, and it is difficult to say in a few words. But everyone can get a couple of important recommendations. The first indicator is the overlap of the sheets. He will hang from the slope of the roof:
- From 30 degrees, the sheets go over each other at 100-150 millimeters.
- From 15 to 30 degrees - 150-210 millimeters.
- Up to 14 degrees - 200 millimeters.
If a non-standard angle
It also happens that the angle of inclination is minimal (for example, 12 degrees). Then it is quite possible to apply sealant. It’s definitely impossible without him. When there is planning of work, it is worth taking the number of sheets, as well as creating conditions for submitting them to the roof in more than one place. Mounting is another important point. It must be done so as not to damage the material. Weather conditions for the installation should be chosen suitable.
Conclusion
So, we found out how to choose the right building material and how to install it. It is worth noting that the laying of the roof is a rather time-consuming process that can take a long time. To reduce this time, you can use the services of professional builders.
When profiled sheets become a topcoat, you can give a countdown of installation work:
- Fastening professional sheets.
- Installation of the crate.
- Work on the counter grill.
- Layout of waterproofing material.
- Rafters with insulation.
- Plywood covering the insulation.
- Vapor barrier.
- Indoor work.
Depending on the purpose of the roof, a heater is selected. These are mainly matte materials. The film of hydro and vapor barrier is fixed with an overlap. To maximize protection, construction tape is used to bond at the joints.
Cutting
An important point is the cutting of the sheets themselves. In the process several options of tools can be applied:
- Jigsaw - the most convenient and fastest way.
- Hand saw with a disc.
- Hacksaw.
The grinder is not used, since it is difficult to achieve the desired result with it. But best of all, when the size of the roofing profiled sheet is cut immediately in the company where the purchase is made. After all, the edged edge must also be enameled, otherwise it will be a weak point of the entire structure. But the ideal fastening component are self-tapping screws with a rubber seal. The final chord will be fixing the skates, parapets and plums. After that, we can say that the roofing work with the professional sheet is completed.
