Metal is a practical and popular material with good strength characteristics, a large selection of variations and an affordable price. You can buy products for the roof of your house or other buildings on the Almet website. The technology of installation of roofing materials is simple, if you know the nuances of work. We will describe features of the process, and also how to put a metal tile correctly.
How to properly place the first sheet of metal on the roof?
The first sheet is placed on the end of the roof with a self-tapping screw on the edge of the ridge and near the cornice. Be sure to consider the eaves (35-40 mm). The next should be overlapped or placed under the first. The second option is more reliable, as better tightness is achieved at the joints. You can go both right to left and left to right. Depends on what is more convenient for you.
How to lay metal sheets?
Tile sheets are equipped with a capillary groove. It is needed so that rainwater or melted snow flows freely from the roof. When laying it needs to be covered with the next sheet. The layout of the material should be chosen in advance.
In what order to lay a metal tile?
The installation process begins with the alignment of the first sheet on the cornice line. Often masters use block fastening. What does it mean? The second is joined to the 1st sheet, but not fixed to the lattice. Then in a similar way the third and fourth. Then the resulting block is aligned relative to the cornice, and fastened to the lattice. There are approximately 6-8 fasteners per square meter.
When laying the roof in several rows, the order is slightly different. First put the first tile, over it the second. Alignment and connection is carried out at the end. Then the third is mounted next to the first, and the fourth above it, etc.
How to properly overlap metal tiles?
The overlap between adjacent sheets is two waves of metal. Joining between the bottom and top row is 10-15 cm, and is done to avoid leakage.
How to lay metal tiles with your own hands
If you understand the course of work in advance, it is not so difficult to lay metal tiles. The operation can be performed independently, with your own hands. The team must have at least two people, which will ensure the quality of the installation.
General technology includes the following processes:
- Preparation of the basis.
- Lifting steel sheets on the roof with homemade logs or conveyor belts.
- Definition of the installation scheme. If one row is mounted, then the alignment of the cornice. The block fastening to a lattice on 3-4 elements is used. When installed in several horizontal rows, the alignment is carried out at the end. Particular attention is paid to the joining of sheets in length.
- Self-tapping screws are screwed into the sole of the wave under the elevation. So they are very invisible. You need to make sure that the elements are in the battens at right angles. It is important to tighten tightly, but do not overdo it.
- After laying the roof, attach additional element holders for gutters, snow, gutters, etc.
- The final stage of removal of debris, metal shavings formed during the drilling of steel. Treats joints with anticorrosive agents.
How many metal tiles do you need and how to choose it
Before laying metal tiles, you need to calculate the amount of consumables, as well as choose the right roofing. What factors do we take into account:
calculate the area of the roof. If a one- or two-sloped roof with a simple geometry, no difficulties should arise. If you have a complex configuration, you should use special formulas;
the calculation of the amount of material should be carried out taking into account that the installation overlaps. You also need to add a margin of 10-15% minimum. The managers of the company where you plan to buy the material can help with the calculations;
when choosing it is necessary to pay attention to the thickness of the steel sheet, the type of zinc and polymer coating, the presence / absence of capillary groove;
it is advisable to order products from large manufacturers that provide quality certificates for the product;
it is obligatory to make inspection concerning absence of chips, scratches, cracks, deflections. The protective film must be intact, the color must correspond to that stated in the receipt.
When ordering, choose the optimal length of the sheet to make it easier to mount, and the parameter corresponds to the roof.
Preparation of a basis under a metal tile
The basis is a lattice, which can be made with your own hands. For this purpose use wooden bars in the size of 50х50 mm or boards of 25х100 mm. The tree must be intact without defects. Pre-treated with antiseptics. The step of laying the lattice should be equal to the distance between the waves. At a cornice it can be less than 3-4 cm. Around chimneys, grooves, bars keep within a continuous layer. The whole structure is mounted on top of the roofing pie (vapor barrier, insulation, waterproofing). Roofing material is sometimes used as a waterproofing layer. Budget option. But you should make sure that the bitumen particles do not get on the polymer layer of the tile, otherwise it will be damaged.
What will be needed for laying metal tiles?
To start work you will need the material itself, fasteners, scissors for metal for trimming, a number of measuring instruments (tape measure), screwdriver, transport logs. The master must be in overalls, soft shoes so as not to damage the tiles.
Instructions for laying metal tiles
General technology includes a number of successive steps:
Preparation of the base (lattice).
Lifting tiles on the roof for 1-2 sheets.
Attaching the first sheet to the skate and cornice.
Joining the 2nd, 3rd and 4th to the 1st to form a block structure.
Alignment of the block on the cornice.
Fastening by self-tapping screws on perimeter, in places of connection to a lattice. At the bottom of the cornice fixation in each wave (depression).
Adherence to regulated overlap.
Arrangement of other roofing elements of a groove, a skate, an end lath, etc.
Cleaning the roof from debris. Treats joints with anticorrosive agents in the form of an aerosol.
The instructions are clear. With proper training, construction skills, and the right tools, work is available in a short amount of time.
Calculation of the required number of sheets of metal
Take the example of a sloping roof. 4-5 meters long sheets are the most convenient for installation. To calculate it is enough to measure the distance between the cornice and the skate, as well as their length. For technical documentation, look at the useful width of the sheet. To make it easier to count, the length of the slope will be equal to the length of the sheet. Thus, to determine the number of sheets, you need to divide the length of the ridge by the useful width of the tile and multiply by 2 (because we have two slopes).
If necessary, the specialists of the Almet online store will help not only with the choice of quality goods, but also make the necessary calculations. This way you will know exactly the exact number of sheets.
