Installation of metal with their hands

Metal largely superior to other types of roofing, such as slate, galvanized sheet metal, shingles, and so on.Laying material likely to trust professionals, but you can perform the installation of metal with their hands.

Product Benefits

the strengths of the metal include:

• low weight (about 4-6 kg / m²);
• ease of installation and repair work;
• a wide range of colors;
• absence of harmful components in the composition;
• high strength (rigidity is achieved through the ribs);when properly installed in a material thickness of 0.5 mm can withstand a load of over 200 kg / m²;
• resistance to temperature changes;
• minimal thermal expansion.

only increased noise during precipitation can be attributed to shortcomings, but it can be solved by mounting the glass wool layer.

Coating metal tile roof begins with calculations.

Step 1. Calculations

First, let us clarify one important point.Visually, the roof covered with this material is made up of rows and waves (the first pass across the ramp).The distance between rows is called a step.If the sheet in step 35 cm tiles and six waves, it is called a module.Modern building materials market offers sheets 1, 3, 6 and 10 modules.

Important!You can order the tiles on the individual sizes, if desired, but it will cost considerably more expensive.It should be remembered that the length of the sheet should not exceed 7 m and be less than 45 cm.

The calculations take into account the layout and the fact that the joints and the waves should form an integral coating on the entire length of the slope.Determine the number of modules on the roof area calculated amount of material.

Besides the metal, the kit also includes:

• strips of steel length of 2 m;
• steel sheets 200h125 cm, having the same color as the tile.

strips are usually designed for roofs made with the slope in 30ᵒ, although, if desired, can be made fit to 11-70ᵒ.

Important!The minimum slope at which allowed the installation of tile is 11ᵒ.

Step 2. Preparation of all necessary

For the installation of tile you need the following equipment:

• metal scissors;
• ladder;
• electric drill;
• longest rail;
• screwdriver;
• mounting tape;
• meter;
• hammer;
• marker;
• personal protective equipment (gloves, plastic glasses).

also need such supplies:

• waterproofing;
• tiles;
• roofing strips;
• aerorolik;
• strip for ridge and ends;
• laths;
• screws, washers, seals thereto;
• board 2,5h10 cm;
• guide board.

Step 3: Base

As stated earlier, metal weighs a little, so reinforced basis does not need - need regular crate of wooden slats.Step crates should be calculated on the size of the tile to the installation does not drive the screws into the void.

Important!When calculating step also takes into account the location of the windows - not desirable to put them over the rafters.

Step 4. Insulation

Insulation is necessary not only to prevent heat loss, but also to protect from the rain noise.First rafters covered with steam insulating material (for example, "Izospanom" or "Yutafol").Next fit insulated layer (thickness not exceeding 25 cm), hiding the antioxidant film and is attached to the rafters with wooden bars.

Important!The material between the bars should be a little slack (about 2 cm), so that condensate can drain off only in the gutter.

Step 5: Assembling of tiles.Basic rules

1. Installation can be done one of two ways.If the right start stacking sheets, each new overlaps the previous one.If on the contrary, that overlap the previous sheet.
2. In order to correct mounting four-leaf tiles, arranged overlap of each other, first grab, aligned, and only then finally connected with one screw.
3. Screws should be of good quality, because of their period of roofing services largely depends.It must be galvanized screws with sealing head of a propylene rubber, sealed filling hole when tightening.
4. At the junction of four sheets appears thickened.It must be removed, which part of the angle is cut or rectified capillary ditch, which is under the stamping line.

Step 6. Individual elements

Step 1. Socket strips are fixed overlapping (about 2 cm).wave size is adjusted to the width of the ramp, or comb can meet at the gable.

Step 2. added roofing lath, then between her and the sheet material is placed an additional seal.

Step 3. At arrangement of tubes or boxes that are below the ridge sheets are taken from one unit - two pieces for each design element.

Step 4. When sloping ramps between the material and the ridge bar is set aerorolik which prevents the penetration of atmospheric precipitations under the horse.

Step 5. Skate fixed on the rails located at the ends of the structure.This must be done in such a way that it extends 2-3 cm. In the case of all flat elements attached ridge overlapping, and if it is semi-circular, according to the profile of the lines only.

Important!If the slope of the roof exceeds 45ᵒ, you should calculate in advance the compatibility of a particular model of the ridge bracket with this angle.If you do not, the consequences can be very dire, until complete replacement of roofing.

Also worth noting is that the strap skates if necessary, you can bend and unbend, so they repeated the angle of inclination of the roof.

Step 7. Construction of the valley

Each valley is secured additional board.Mounting in this case starts from the bottom and is performed in the overlap of 25-30 cm. Below the cornice clipped the bottom bracket, it is made by flanging.Under each obortovku horse and is enclosed seal.

gap remains (at least 8-10 cm) between the axle and the sheets.The cut sheets and a half inches from the stamping line twist screws.However, when fixing the fixture is made of 25 cm from the axis of the valley.If everything was done correctly, at the end of the work sheet in place of fixture will be in contact with the board, where the valley.

Important!If mistakes have been made, then the fixing will be in other locations, and as a result, gaps are formed on the surface through which the roof will leak.

To cover trimmed sheets laths are used, the installation of which need to be aware of some important points:

• installation must be done from the bottom up;
• between the tiles and the lining is not necessary to lay the seal;
• products lie overlapping (minimum 10 cm);
• screws used to fix the lining, must not damage the valley.
  

  Protection valley

often beginning and ending valleys are on the roof slope.Take, for example, the installation of a roof window.Here the valley is enclosed by a separate board.For the window cut-out in the list is done, and the sealing material is placed along the walls.This overlaps the eaves bar.

then locked the valley strips, pre-cut at the edges.Released Keep as tightly stick to the sheet of tile.

rays in trapezoid or triangle

If the roof slopes have a trapezoidal or triangular shape, it is necessary to install additional bars.

Step 1. bars are mounted on either side of the "backbone" on the roof of the fold line.

Step 2. Set cornice board is going to crate.

Step 3. constructs curtain systems.

Step 4. It is placed tiles.This is accomplished through one of the edges or axes.Frontpage attain to the level of the cornice at the bar.

Important!It is unacceptable that the distance between the cut angle plates installed near the "ridge", was more than 10 cm.

Step 5. the following actions to install ridge units.Skating strips are aligned with the corner of "ridge".If you are using a straight horse, it is cut according to the corners, and if the semi-circular shape, the installation will require additional plugs (preferably plastic).

Step 6. Ridge lath falls strictly under the "ridge" axis.Run is just enough if the same angles rays, and if different, that, accordingly, difficult.To control the junction rays mounting tape used bright colors.

Features care material

As already mentioned, the metal is covered with a polymer layer, which protects against corrosion.But constant exposure to ultraviolet radiation, precipitation and dust sooner or later becomes the cause of destruction of the protective layer.That is why metal roofing should be cleaned regularly.

1. dirt and dry leaves are washed away with a damp lint brush.
2. To remove more difficult dirt, you can use special cleaning agents for plastic surfaces.
3. not use aggressive chemical agents - they can destroy the protective layer.
4. Drains cleaned by water jet under pressure.The spray should be directed from the ridge to the eaves.
5. only those tools that, in principle, unable to damage the coating can be used to clear snow from the roof.

If all these rules metal will last about 50 years.
