When a person plans to build his own house, it is important for him to choose a quality material. In addition, everyone wants to save money. Many people want to choose the most reliable and at the same time cheap material. Roofing profiled sheet can be considered just such a building component. Often you can encounter such a problem as the lack of information about a particular model. Not every salesperson is at their best.
So that nothing like this happens, you need to stock up on information before starting the choice. This will help you make the right choice and create the conditions for a quality building for many years to come.
Roof profiled sheet
Profiled metal sheets have become actively used in any construction. This is the choice of not only professional masters, but also beginners. This constituent component is suitable for roofing, although today it is also used in other areas. Each building material has its own characteristics, and it is they that confuse an inexperienced craftsman. But basically it is worth paying attention to the thickness and quality of the coating.profiled roofing sheet.
Before you buy, you should understand these indicators in order to accurately select the right one. After all, the manufacturer guarantees quality only with proper application. There is a whole range on the market, used for its intended purpose:
- For the walls of outbuildings.
- Sheds.
- Fences.
- Ceilings.
- For the roof.
It is clear that the main thing is to choose the right profiled roofing sheet. Because he has a lot of serious tasks. In addition, he is exposed to all natural phenomena, and the roof over his head must be reliable.
How to choose?
Before buying, you should understand what we are dealing with. This is a profiled metal sheet with many rigid 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. Rolled steel is used to create. Separate sheets are made on special devices. Their configuration affects the overall strength.
In addition, additional processing is used in production. It makes things even better. You can compare a professional roofing sheet with a cake in several layers:
- Steel sheet is the basis.
- Then comes zinc coating on both sides.
- Further, compounds are used that resist corrosive effects. Application is carried out around the entire perimeter.
- Another component,that allows you to create maximum protection - this is a primer.
Today, galvanized roofing profiled sheet can have a different color scheme. It is clear that special paints are used at the production level. This is a unique creation system, after which the original design of the 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 processing.
- Aluminum or copper. According to the characteristics, this material is similar to the previous one.
- Roofing in several variations - perforated, rolled, for various textures, bent.
- Galvanized profiled roofing sheet, but without additional coating. Its cost is lower, but the service life is short. It is rarely seen on the roof. Used more often for outbuildings.
All of the listed roofing profiled sheets have different thicknesses. In addition, the masters of the construction business recommend that when buying, pay attention to the fact that the full width differs from the useful one. There are such types of elements:
- Carrier.
- Facade.
- Wall.
- Ceiling.
- Formwork.
When buying, there are many questions. It is necessary to decide in advance which type is suitable. Only in this way will the purchase be made correctly and it will become easy to cover the roof.
What should you keep in mind when choosing?
There are three easy directions,that will help make the choice correct and error-free:
- When buying, pay attention to the thickness and level of additional coverage (to create an ideal roof, a load-bearing and wall one is suitable). At the same time, in the first there is an additional recess, which gives its advantages. As a result, when the roof is overlapped, a good groove under the water is formed. The beginning will be at the ridge, and then - to the drain. But the wall does not have such a feature.
- When a professional sheet with a capillary groove is chosen, then in the store it is worth finding out if it bends. Because some manufacturers do not make it reliable, and when it bends, its main purpose (protection) is lost.
- To cover the facade of the building by fixing the roofing profiled sheet is quite appropriate. But in 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 specified parameters.
Building material grades
It can be noted that the characteristics of the profiled roofing sheet 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:
- С-21. According to the masters, this is the best model of profiled sheets for creating a high-quality roof covering. But before that, you need to createa suitable crate so that the step does not exceed 0.7 meters.
- NS-35 - profiled 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 solid roof, because there are additional stiffeners.
- RN-20. This is a unique material because it fits in any direction. It has a drain groove, and the working area is more than 1 meter.
What do these letters mean?
C and H are the beginning of the names (wall and load-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 firms that produce according to GOST, since the technical conditions no longer provide high quality. It is always worth asking the seller for a certificate.
Types of building material
When choosing, you need to pay attention to the main indicators: cost, type, external data, angle of inclination of the roof. Pricing is everyone's business. There is no need to talk about it much, because the finishing budget is calculated individually. But the rest must be taken into account. If the quality is too low, then you should think that the manufacturer was saving. But mainly additional coating and thickness affect this indicator.
Sometimes there is such a feature that the same material at different points of sale has different price parameters. 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 cut sheets to the desired length. If you communicate with the masters, they help not only to correctly calculate the required amount per roof, but also suggest what components will be needed during the installation of the roofing profiled sheet.
Covering
The coating of the material itself can be different (as well as the thickness of its application). It is good to use bright colors for the roof, as they have an additional application - this is plastisol. Polyester is chosen by those who care about external indicators. But the material is not so effective when exposed to the outside. The best option is plastisol, since it practically does not fade, it is resistant to damage. But its price will be higher than the usual option.
The polymer used in the polyurethane-based coating withstands all negative precipitation. As a result, the building 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 figure increases, then the corrosion resistance will be better. It is the external indicator that is important for designers, but the masters of the construction business say that the appearance also affects the quality.
Inspection
Few people focus on a thorough inspection of the roofing profiled sheet. This is a mistake, because then it will be too late to prove that it was marriage that was acquired. In order for the roof covering to last for a long period of time, it is necessary to completely eliminate suchmisunderstandings:
- Uneven paint.
- Colour transitions when material is uneven.
- Chipped or small cracks.
- The strength of the paintwork layer (whether it crumbles or not).
In this case, the sheets themselves must be even, including the edges. With a slight bend, 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, the load is distributed, which affects the service life of the entire structure. Therefore, the appropriate material is selected at the planning stage.
These are the simplest recommendations that will help you select the required material without any problems. Only such a roof will become a reliable protection for all residents. And the owner will not spend money in vain. In order for the structure to serve 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/m2), therefore, when carrying out work, this fact must be taken into account. It can't always be done by one person. Today, there are several styling methods. 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 sheets. It will hang from the slope of the roof:
- From 30 degrees the sheets overlap each other by 100-150 millimeters.
- From 15 to 30 degrees– 150-210 millimeters.
- Up to 14 degrees - 200 millimeters.
If 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. Without it, you definitely can't. When planning work, it is worth selecting the number of sheets, as well as creating conditions for feeding them to the roof in more than one place. Mounting is another important point. Care must be taken not to damage the material. Weather conditions for installation should be chosen appropriate.
Conclusion
So, we found out how to choose the right building material and how it is installed. It is worth noting that laying the roof is a rather laborious process that can drag on for a long time. To reduce this time, you can use the services of professional builders.
When the profiled sheets become the finish, you can count down the installation work:
- Fixing profiled sheets.
- Installation of the crate.
- Work on the counter-lattice.
- Laying waterproofing material.
- Rafters with insulation.
- Plywood covering insulation.
- Vapor barrier.
- Indoor work.
Depending on the purpose of the roof, insulation is selected. Basically, these are matte materials. The film of hydro- and vapor barrier is fixed with an overlap. To maximize protection, construction tape is used to fasten at the joints.
Cutting
The important point is the cutting of the sheets themselves. Several tool options can be applied in the process:
- Jig saw is the most convenient and fastest way.
- Hand saw with disc.
- Hacksaw.
Bulgarian is not used, as it is difficult to achieve the desired result with it. But it is best when the roofing profiled sheet is cut to size immediately in the company where the purchase is made. After all, the trimmed edge must also be treated with enamel, otherwise it will be a weak point of the whole structure. But the ideal fastening components are self-tapping screws with a rubber seal. The finishing chord will be the fixation of skates, parapets and plums. After that, we can say that the roofing work with the profiled sheet is completed.
