How to make a roof of metal profile with your own hands: technology and practical advice

To protect the roof today can be used a variety of materials. One of the most popular certainly is the sheets (corrugated sheet). It is made by cold rolled steel of high marks. Make a roof from metal sheets if desired with your own hands, as one of the obvious advantages of this material is the ease of installation. Used corrugated sheets for roofs of all sizes and configurations. Today, such roofs can be seen everywhere.

What is a corrugated sheet

Sheet metal is a plate of fairly thin metal (0.5 to 1 mm) coated with a polymer layer. Its surface is made in the form of waves. The dimensions of the metal sheets for the roof can be very different. When choosing a kind of material, you must first pay attention to wave height and thickness used to manufacture metal.

The Main advantages of corrugated sheets

The main advantages of metal profile, in addition to ease of installation sheets, include:

• Light weight (from 3 to 20 kg);
• Fire resistance;
• Environmental cleanliness (sheets completely safe for human health);
• Durability (sheets of this material are not afraid of UV exposure, temperature changes, acid rain, etc.);
• Price (corrugated sheet – one of the most inexpensive materials today);
• Aesthetic appeal;
• High degree of strength;
• Recyclability.

Disadvantages of metal profile

The disadvantages of this material is attributed primarily noise. However, when using a sufficiently thick insulation layer, which in this case may be considered as noise, the effects of such disadvantage can be reduced almost to zero.

If the damage of the external decorative layer on the leaves can develop corrosion. Some disadvantage is the fact that, arranging a roof of metal sheets, we need to ensure that the joints between the elements were as sealed. Otherwise, the finished roof will leak.

Types of material

Speaking of applications, there are three types of sheets:

1. Material brand “”. Used for finishing walls.
2. Profiled Sheet brand “N”. Has the most high strength characteristics and can be used for roofing.
3. Material brand “HC”. Can be used for the device of fences, walls, and protection of roofs.

Actually corrugated sheet – this is the cheapest kind of metal profile. Besides him, there is the metal – very aesthetic and practical material. The roof, covered it, looks great. Thus, the corrugated sheet and metal – the main types of metal profile for the roof.

Milestones in the construction of this roof type

Installation of a roof of metal sheets is performed in several stages:

• The unit truss system;
• Installation of a vapor barrier;
• Installation of insulating material, while most commonly used mineral wool;
• Installation of waterproofing layer;
• Device sheathing;
• Installation of drainage system;
• Installation of sheet metal profile;
• The covering of the rafters from the attic.

Steam-, hydro - and thermal insulation in this case is arranged in exactly the same way as for any other roofing material. The crate is stuffed with the size of sheets of sheets.

Installing drainage systems

Before starting the installation of the roof metal sheets, it is desirable to arrange the drainage system. At the first stage on the crate are fixed the holders of the gutter. The edge of the latter should ultimately be located approximately 3 cm below the edge of the future roof. Otherwise possible deformation when snow melts in the winter. After the holders are installed, they inserted the gutter. Next to the crate is attached to the eaves plank. Its installation is performed so that the overlapped edge of the gutter. Also on top of the eaves plank will need to bring the edge of the waterproofing membrane.

Calculation of a roof of metal profile

The Roof of metal profile with your own hands will be arranged with the savings in that case, if they made the necessary calculations. In this regard, consider especially:

1. The Number of elements in a horizontal row. For this we first measure the length of the roof. Of course, respectively in the horizontal direction. The resulting figure is divided by the width of the sheet. Also take into account the length of overlap between elements.
2. To calculate the length of leaves and number of rows needed for the length of the slope (vertically) to allow the length of overlap and the length of the overhang.

To find out how much you will need screws, it is necessary to calculate the area of the future of the roof and the resulting figure multiplied by 6.

Training materials

Before you begin installation of the roof, you need to prepare the tools. At hand should be:

• Constructionlevel and plumb;
• Tin snips or a jigsaw is needed for cutting sheets;
• Soap;
• Pencil and square;
• Screwdriver;
• Screws.

The corrugated sheets must be transported and raise the roof with maximum accuracy. Otherwise, you can damage the protective polymeric layer.

Installation worksheets on rays

Now let's see what actually gets a roof from metal sheets with your hands. Mounting plates start from the bottom. To the sheathing they are fastened by screws at the bottom of the wave. This will ensure reliability of installation. The overlap must occur not less than one wave. One 1m² of the roof shall be at least 6–7 screws. Horizontal overlap (between the rows) should be about 20 cm

Trim pediment

In the production of calculation required for the cladding of gable material is taken into account, exactly how it will be laid. The most economical is considered a horizontal mounting method. In addition, in this case, the house will look more aesthetically pleasing. In the calculation it is necessary to consider the fact that prirezku takes about 10–15%.

For the entrance is quite suitable wall corrugated sheet brand “”. You can also use the material “N” and “HC”. After performing heat - and waterproofing mounted frame of wooden slats. They will need to pre-consolidate windproof film. The sheet then can be cut using a hacksaw on metal or jigsaw.

Arranging a roof from metal sheets, should be extremely careful in terms of the possibility of damage to the polymer coating. Otherwise, you will significantly reduced the lines of a design, as the elements will eventually begin to rust. So use for cutting the sheets the grinder is not recommended. To strengthen cut the sheet to the frame should start from the bottom corner. All elements are mounted overlapped.

Installation of seahorse

The Device of a roof of metal profile also includes the installation of the skate. The junction of the rays at the top closes the ready-made item that can be purchased simultaneously with the purchase of sheets. The skate is made from the same material as the main elements. He needed to prevent under sheets of water. Laying in this case should begin to run from the opposite direction prevailing in the specific area of the winds side. Are mounted the skating elements with an overlap of 15–20 cm in the ridge with a pitch of 20-30 cm For mounting use the screws.

In that case, if the angle of slope of the small roof, under the ridge elements should be put a special sealant, which can also be purchased at the hardware store. Between him and the crest should be a small ventilation gap.

Setting the valley

Mounting a roof from metal sheets, it is necessary among other things to properly install valley. In this case, it is very important to good sealing. The valley is called the trough, included in the internal oblique crossing of the slope. It is mounted on a solid crate, arranged on both sides. Horizontal elements are joined with an overlap of 10–15 see the joints in the mandatory treated with a sealant. In order to better induna strap was attached to the roof, use a special self-expanding seal.

At the moment it seems more than appropriate use for the protection of the roof of such modern material as the sheets. The installation of the roof in this case can be performed in a short time and without the involvement of professionals. For a little money home owners will receive a reliable protection of its interior from all adverse environmental factors.
