The professional sheet is actually a universal building material. It is widely used to implement a wide variety of ideas. At present, very attractive and elegant roofs are found, which are covered with a bright professional sheet.
General information
In most cases, monophonic overlapping can be seen. However, there are also geometric patterns in the form of rectangles and stripes. Due to this, the roofs of houses have their own special style. Some homeowners are wondering: how to cover the roof with a professional sheet with their own hands? In addition, many do not know how to care for him. In this case, it is recommended that you familiarize yourself with all the nuances inherent in this material. After that, it will be possible to work with him independently.
Clear benefits
Laying the profiled sheet on the roof has its own characteristics. Before installing it, you should familiarize yourself with the advantages of this material. Many would like to carry out all the work on their own. This is not surprising, since currently hiring a professional team of workers is quite expensive. In this case, you can do without it. A roof made from a profiled sheet, made with its own hands , is a completely feasible task. This is the main advantage of this material.
Additional Information
Roofing with a profiled sheet is best done in three. At the same time, assistants may not have special knowledge in this area. Laying the profiled sheet on the roof is carried out by technology. In general, the work is not particularly difficult. Even beginners will cope with this task. Arranging a roof from scratch or overlapping it can be done in a fairly short period of time.
Main characteristics
Many begin to think about how to properly cover the roof with a professional sheet. After all, the roof must be reliable and durable. Here a few words should be said about the material itself. Its main component is a cold-rolled metal sheet. In most cases, it is coated with polymer on top. Due to its thickness, the profiled sheet is quite resistant to wind loads. The paint coat is also very important. It prevents corrosion and precipitation from damaging the coating. Naturally, in this case, the installation result will turn out to be quite reliable.
Preliminary calculations
Before covering the roof with a professional sheet, you need to take into account the climatic features of a particular region. For example, in an area where a large amount of snow falls in the winter, it is best to choose a material of the appropriate thickness. Recommended profile height - not less than 20 mm. The cost of this material is quite affordable. This also applies to all additional roof elements. So, we can assume that the question of the reliability of such a roof is closed.
Accounting for the necessary materials
Before you cover the roof with a professional sheet, you need to calculate the required number of elements. There are a few things to consider. First of all, you need to take into account the fact that the sheets are mounted with an overlap. The edges of the material are superimposed both horizontally and vertically. In addition, there is a need to take into account the size of the overhang of the roof. The calculation of vertical overlaps depends on the profile. It should be carried out with overlapping waves. Different brands of profiled sheets have different wave steps. The amount of material will be calculated according to the angle of the ramp. Only after all these calculations have been completed can you start covering the roof.
Horizontal overlap
Its size depends on the angle of the roof slope. Further it is required to be guided by the following recommendations:
- Slope angle up to 15 degrees. Then the overlap can be more than 20 cm.
- The slope angle in the following limits: 15-30 degrees. In this case, the amount of overlap varies: 15-20 cm.
- The slope angle is more than 30 degrees. Recommended overlap size is up to 15 cm.
The size of the overhangs depends on the brand of the profiled sheet. In this case, we are talking about the height of the ribs. If the overhang is small, then moisture can get under the roof. Thus, the decay of the wood from which the rafter system is made will inevitably occur.
Steam and waterproofing
This must be taken care of before covering the roof with a profiled sheet. For vapor barrier, special films are used. It is worth noting that the range of such products in specialized stores is very wide. Roofing material is recommended to be used only as a last resort.
Working process
Ruberoid or film is attached to the rafters using a stapler. Then comes the crate. It should be noted that these elements should be stacked from the bottom edge of the roof. Due to this, moisture will not be able to penetrate the wood. It should be noted that the device of the crate depends on the brand of the profiled sheet. At a certain thickness of the material, it must be made continuous. In most cases, the step of the crate is set in accordance with the angle of the slope of the roof and the size of the profile. Basically, it is in the following range: 50-100 cm. Moreover, each wooden element of the rafter system must be treated with a special antiseptic. Thus, the tree is protected from fire and decay.
How to mount a professional sheet on the roof: basic recommendations
In this case, it is required not only to correctly lay the material. It is also necessary to deal with interfloor ceilings. Speaking about how to mount a professional sheet on the roof, it is necessary to say about some of the nuances in the work. In particular, this applies to the delivery of material. It is also necessary to pay due attention to its rise on the roof. It is recommended to be careful. Otherwise, the corrugated sheet may be damaged or scratched. When covering the laths, it is also important to be extremely careful. In addition, you should take care of security. Before covering the roof with a professional sheet, it is recommended to wear protective clothing and gloves. It is recommended to walk on the roof exclusively in soft shoes. In this case, one should step on the ridge. During installation, the correct determination of the type of rafter system is of great importance. This also applies to the step in accordance with which the placement of elements. The performance is affected by the type of material and plumb angle. Roofing is necessary only taking into account these parameters.
Mounting Features
Before covering the roof with a professional sheet, you need to decide on the flooring option. Then you need to work with the plank flooring under the valleys of the valley. Next is the fastening of the end elements.
How to cover the roof with a professional sheet?
Directly mounting itself begins with the laying of the cornice strip. It should be noted that it must be located below the waterproofing layer. Then you can start attaching profiled sheets. This must be done from the end. Hip roofs are common. In this case, the algorithm of actions is slightly different. Work begins at the center of the hip. Fastening one sheet will require about 7-8 screws. Some joints should be given special attention. In some cases, steel rivets are used. Before completing the strengthening, it is imperative that all sheets be aligned to the end of the roof slope. In this case, the overlap of the material is calculated taking into account the angle of the ramp. The lining size is 150-200 mm. The overlap should not be less than one wave.
Installation of additional elements
Laying corrugated board involves placing places near the ridge of the roof, pipes and valleys using metal sheets. All this can be done independently.
Dormer window
In this case, the construction of a short valley is implied. It is necessary to cut the sheet near the lower edge of the groove. You should get two identical parts. This is necessarily taken into account in the calculations of materials for installation works. First, put the bottom sheet. After it comes the bottom film. Then comes the turn of the roofing sheet.
End element
The length of the strap is about two meters. Recommended material overlap is 50-100 mm. Installation itself should begin on the plumb side. Next, you need to move towards the ridge of the roof. Near it, you need to cut off the excess. The entire end plate must be covered (at least one wave of corrugated board). Next, it will be necessary to attach it to the corresponding board, as well as profiled sheets in the comb. Recommended step is 1 meter.
Ridge level
In this case, specialized smooth elements are used. According to the recommendations of specialists, under the profiled sheet should be installed seals. They should be with a small corrugation or repeat the profile of the roof itself. Recommended overlap length - from 100 mm. On the side of the sheet, you need to fix the bar using self-tapping screws. Recommended pitch is 400 mm. Each fastener, made independently, should be under the skin or in the gate. In this case, the ridge seal is used for protection. Side abutment is set up a little differently. For these purposes, a longitudinal seal is required. It can not be used on steep slopes.
Feedthrough elements
Each output pipe consists of two parts: upper and lower. The latter is selected in accordance with the profile of the roof. It is recommended to install the snow pack immediately. The recommended pipe diameter is 100 mm. Ventilation elements need insulation. Here's how to cover the roof with a professional sheet.
Some rules of care
In principle, this process is also not particularly difficult. In order for such a roof to clear, ordinary rain will be quite enough. However, water is unable to carry branches, leaves and other debris with it. For this reason, regular surface cleaning is recommended. This must be done every year. Gutter systems also need regular cleaning. This also applies to grooves. Heavily polluted places are often found. They can be washed with a soft brush. It can also be done with water from a hose. Recommended pressure is up to 50 bar. It happens that the dirt eats heavily into the roof. In this case, you need to use special tools that are designed to clean painted surfaces. There is a simple algorithm of actions. First you need to apply the product on the surface. For a better impact, it will take him a few minutes. Next, the product is washed off with clean water. Complex stains should be cleaned with rags. It is pre-soaked in a solvent. Then the roof must be rinsed with water. It is highly recommended not to clean the roof with products that are not intended for this. The fact is that with a similar effect, the sheet or surface of the polymer may be damaged. Ice and snow are removed on their own. To do this, you can use wooden or plastic spatulas. In this case, care must be taken. Otherwise, scratches cannot be avoided.
