How to cover the roof with a profiled sheet. Correct fixing of corrugated board

The profilist is in fact a universal building material. It is widely used to implement a variety of ideas. At present, very attractive and elegant roofs are often found, which are covered with a bright profiled sheet.

General information

In most cases, you can see single-color overlap. However, there are also geometric patterns in the form of rectangles and stripes. Thanks to this, the roofs of houses have their own special style. Some homeowners are wondering: how to cover the roof with a proflist sheet with your own hands? In addition, many do not know how to care for him. In this case, it is recommended to familiarize yourself with all the nuances inherent in this material. After that, you will be able to work with it yourself.

Clear Advantages

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 do all the work independently. This is not surprising, since at present the hiring of a professional team of workers is quite expensive. In this case, you can do without it. The roof of the profiled sheet, with its own hands, is quite feasible. This is the main advantage of this material.

Additional Information

Cover the roof with a profiled sheet is best made by threesome. In this case, assistants may not have special knowledge in this area. Laying of the profiled sheet on the roof is carried out according to the technology. In general, the work is not particularly difficult. Even novices will cope with this task. The construction of a roof from scratch or its overlap can be done in a fairly short period of time.

Main characteristics

Many people start to think about how to properly cover the roof with a profiled sheet. After all, the roof must be reliable and durable. Here you should say a few words about the material itself. Its main component is a cold-rolled metal sheet. In most cases, it is coated with a polymer on top. Due to its thickness, the profiled sheet is quite resistant to wind loads. Also very important is the paint and varnish layer. It does not cause corrosion and deposits damage the coating. It is natural that in this case the result of the installation will turn out to be quite reliable.

Preliminary calculations

Before you cover the roof with a profiled sheet, you need to take into account the climatic features of a particular region. For example, in an area where a lot of snow falls during the winter, it is best to choose a material of the appropriate thickness. The recommended height of the profile is not less than 20 mm. The cost of this material is fairly affordable. This also applies to all additional elements for the roof. So, we can assume that the question of the reliability of such a roof is closed.

Accounting for required materials

Before you cover the roof with profiled sheet, you need to calculate the required number of elements. Here you need to consider several points. 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 roof overhang. Calculation of vertical overlaps depends on the profile. It should be carried out with overlapping waves. Different grades of profiled sheet have a different wave pitch. The amount of material will be calculated according to the angle of the ramp. Only after the completion of all these calculations can begin to cover the roof.

Horizontal overlapping

Its size depends on the angle of the roof slope. Further it is required to be guided by following recommendations:

1. The angle of the ramp is up to 15 degrees. Then the allowance can be more than 20 cm.
2. The angle of the ramp in the following limits: 15-30 degrees. In this case, the amount of admission varies: 15-20 cm.
3. The angle of the ramp is more than 30 degrees. The recommended size is up to 15 cm.

The size of the overhead depends on the size of the overhangs. In this case, we are talking about the height of the rib. If the overhang will be small, then under the roof can get moisture. Thus, inevitably there will be decay of wood from which the roofing system is made.

Steam and waterproofing

This should be taken care of before covering the roof with a profiled sheet. For the vapor barrier, special films are used. It is worth noting that the range of similar products in specialized stores is very wide. It is recommended to use the ruberoid only as a last resort.

Progress

A ruberoid or film is attached to the rafters using a stapler. Then comes the turn of the crate. It should be noted that these elements must be stacked from the bottom edge of the roof. Due to this moisture can not penetrate to the wood. It should be noted that the device of the lath depends on the brand of the profiled sheet. At a certain thickness of the material, it must be made solid. In most cases, the step of the crate is set in accordance with the angle of the roof slope and the size of the profile. In general, it is in the following range: 50-100 cm. At the same time, each wooden element of the truss system must be treated with a special antiseptic. Thus, the tree is protected from fire and rotting.

How to fix a corrugated sheet on the roof: basic recommendations

In this case, it is required not only to properly pack the material. It is also necessary to deal with interstorey floors. Speaking about how to fix the profiled sheet on the roof, it is necessary to say about some nuances in the work. In particular, this refers to the delivery of material. Also it is necessary to give due attention to its lifting to the roof. It is recommended to be careful. Otherwise, the corrugated sheet may be damaged or scratched. When covering the battens it is also important to observe the utmost care. In addition, care should be taken to ensure safety. Before coating the roof with a profiled sheet, it is recommended to wear protective clothing and gloves. On the roof it is recommended to walk exclusively in soft shoes. In this case, it is necessary to step into the crest. When installing a great value is the correct definition of the type of rafter system. This also applies to the step according to which the elements are positioned. The parameters are affected by the type of material and the angle of the plumb line. Cover the roof only with these parameters.

Mounting Features

Before you cover the roof with a profiled sheet, you need to decide on the option of flooring. Then it is necessary to work with the plank flooring under the slats of the valley. Further, the end elements are fastened.

How to cover the roof with a profiled sheet?

Directly the installation itself begins with the laying of the cornice bar. It should be noted that it should be located below the waterproofing layer. Then you can start fixing the profiled sheets. This must be done from the butt. Often there are hip roofs. In this case, the algorithm of the action is slightly different. Work begins with 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 the completion of the reinforcement, all sheets must be leveled along the butt of the roof slope. At the same time, the overlap of the material is calculated taking into account the angle of the ramp. The size of the lining is 150-200 mm. The overlap should not be less than one wave.

Installation of additional elements

Laying corrugated board involves the design of places near the roof ridge, pipes and ends using metal sheets. All this can be done independently.

In this case, the construction of a short valley is meant. It is necessary to cut the sheet near the bottom edge of the slot. There should be two identical parts. This is necessarily taken into account in the calculation of materials for installation work. First, put the bottom sheet. After it comes the bottom film. Then comes the turn of the roofing sheet.

End piece

The length of the bar is about two meters. The recommended overlap of the material is 50-100 mm. The installation itself should begin at the plumb line. Next you need to move towards the ridge of the roof. Near it, you need to cut off excess. Should be covered (not less than one wave of corrugated board) the entire end plate. Next, it will be necessary to attach it to the corresponding board, as well as profiled sheets in the comb. The recommended step is 1 meter.

Ridge

In this case, specialized smooth elements are used. According to the recommendations of experts, the profiled sheet should be sealed. They should be with fine corrugation or repeat the profile of the roof itself. The recommended lap length is from 100 mm. On the side of the sheet you need to fix the bar using self-tapping screws. The recommended step is 400 mm. Each mount, made independently, should be under the skin or in the shtrobe. In this case, the ridge seal is used for protection. The side adjacency is arranged differently. A longitudinal seal is required for this purpose. It can not be used on steep slopes.

Feedthrough elements

Each outlet pipe consists of two parts: the top and bottom. The latter is selected in accordance with the profile of the roof. It is recommended to install the snowshoe immediately. The recommended pipe diameter is 100 mm. Ventilation elements need to be insulated. That's how to cover the roof with a profiled sheet.

Some rules of care

In principle, this process is also not very complicated. In order for such a roof to clear, it will be enough ordinary rain. However, the water is unable to carry branches, leaves and other debris. For this reason, it is recommended to clean the surface regularly. This must be done every year. Gutters also need regular cleaning. This also applies to the races. Often there are heavily polluted places. They can be washed with a soft brush. Also this can be done with water from a hose. The recommended pressure is up to 50 bar. It happens that dirt is strongly ingrained in the roof. In this case, you need to use special tools that are designed to clean the painted surfaces. There is a simple algorithm for action. First you need to apply the product to the surface. For better impact, it will take several minutes. Then 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 discouraged to clean the roof by means that are not intended for this purpose. The fact is that with such an effect, the sheet or surface of the polymer can be damaged. Ice and snow are removed on their own. You can use wooden or plastic blades for this. In this case, you need to be careful. Otherwise, the appearance of scratches can not be avoided.
