When constructing a roof, metal roofing is increasingly being used. Modern, lightweight and durable material is very popular due to the mass of advantages over others. In this article, we will tell you in detail how to install it. Do not be afraid to take on the installation of the roof, because having learned how to cover the roof with metal tiles - the video material about which we recommend watching, you will do an excellent job.
Preparing the roof for installation of the coating
Before starting roofing work, it is necessary to prepare the base. Carefully measure the slopes diagonally. If the dimensions match, then the roof is flat.If distortions are observed, they must be eliminated by aligning the edges of the overhangs in a straight line.
Who knows how to properly cover the roof with metal tiles, more than once faced with the fact that the roof that was not aligned in advance leaked in the future.
The next step can be considered the manufacture of a batten, for which a board with dimensions from 10 × 2.5 cm is suitable. For a counter-batten, a beam of 5 × 2.5 cm is taken.
Strictly along the line of the overhang of the cornice, the first board of the future crate is nailed. The thickness of the first board should be 1-1.5cm more than the others. This must be done in order to equalize the difference in the levels of the support points of the initial and subsequent sheets of tiles.
Between the board going to the eaves and the distance following it should be 30 / 40 cm. All subsequent batten boards are mounted 35-45cm apart. This distance will depend on the dimensions of the tiles you purchased.
Advice! To determine the desired distance, you can put two pieces of boards parallel on the ground, then cover them with a sheet of tiles. It will be seen how much the protrusion of the element will allow water to drain. A very large protrusion is undesirable, as the water will overflow, and a small one will cause the wind to blow the tiles between the gutter and the board.
To understand how to properly cover the roof with metal tiles, it is advisable to try to lay several of its sheets on the boards in advance and measure the optimal distance. Then the crate will turn out to be of high quality and reliable.
After its installation, you can attach the ridge and wind strips. The wind bar is attached above the crate at a distance equal to the size of the tile sheet. The skate is additionally fixed with boards.Then attach the cornice strip to the roof overhang.
Brackets for fastening future gutters are also installed before laying the tiles. They are located 50-60 cm apart, taking into account the slight slope of the gutter for water to flow down it.
The gutter is fixed on the brackets, and the eaves rail is installed on the crate in such a way that the lower edge of the gutter is blocked by its lower edge. This is necessary to drain the condensate that collects on the film into the gutter.
After the final installation of the crate, before the metal tile is laid, the roof must be lined with layers of insulation, as well as hydro and vapor barrier. Along the way, ventilation and chimney pipes are brought out.
Insulation is not required if a cold roof is provided and the room is intended for business purposes, and not for living.
The vapor barrier film is laid as the first layer. It will protect the next layer of insulation from moisture coming from inside the room. The film is laid, carefully fastening the seams with a special adhesive tape.
Next, you can lay a layer of insulation, which also has soundproofing properties. The third layer is made out with a waterproofing film, the seams of which are also neatly joined with a slight overlap and fastened together.
If the roof is not carefully prepared, the metal tile will not lie flat, and this is fraught with roof leakage and frequent repairs. After all the preparatory work, you can proceed directly to laying the roofing sheets on the roof.
Required Tools
For self-assembly, you will need the following tools:
- screwdriver or electric screwdriver;
- hammer;
- long straight rail to control straight lines;
- markers;
- special scissors for cutting metal;
- cutting electric scissors;
- jigsaw;
- hacksaw for metal.
After all the materials and tools have been purchased, and the roof has been prepared for installation, we proceed to the most important moment - we cover the roof with metal tiles.
Tiling
If you plan to cover a hipped roof, you should start laying from the highest point, moving evenly down. The gable roof is covered starting from the left or right end. Starting from the right, set each subsequent sheet on the last wave of the previous one.
If you started on the left side, then the next sheet is inserted under the wave of the previous one.
The installation sequence should be as follows:
- The first sheet at the ridge bar is attached to the crate with a self-tapping screw;
- The next coating element is set so that the lower edge is perfectly even, then the overlap is fastened with a self-tapping screw from the outside of the wave under the lower part relative to the first convexity.
- The quality of the joints between the sheets is checked, insufficient or uneven overlaps are leveled by slightly lifting the top sheet and leveling the bottom one. The sheets are fastened with self-tapping screws along the top of the wave. It is important to ensure that the screws do not touch the crate, otherwise the sheets will not be able to move when leveling.
- After installing 3-4 sheets of tiles, the lower edge is carefully aligned with the eaves. Only after that the sheets are finally fixed.
- Next, you should cover the roof with metal tiles in the same sequence, so that each subsequent sheet is placed under the previous one with the same overlaps.
Advice! During installation work, you will probably encounter the problem of cutting sheets. It is impossible to cut a metal tile with a grinder or abrasive cutters. The fact is that heating up and melting from such tools, the coating of the sheets is destroyed, which is why the tile will become unusable in the future. Therefore, you need to use special scissors for metal or an electric saw.
If the edges of the sheet are still damaged, they should be painted with a special protective paint. The same is recommended to be done in case of accidental formation of chips and scratches on the sheets. Otherwise, the sheet will quickly rust from moisture and the roof will have to be repaired.
Before covering the roof with a metal tile, if partial repairs are necessary, it is necessary to unfasten the sheets adjacent to the damaged one.
When laying the shingles, make sure that the edge of the gutter is just below the edge of the shingles. The size of the indent should be 2.5-3cm.
A properly positioned gutter relative to the roof will prevent snow from damaging it. Gutters with a round profile are inserted into fixed holders at the back.
Gutters having a rectangular profile are inserted into the holders, according to the instructions attached to them, and fixed.
When roofing a roof with a metal tile with your own hands, you should pay attention to all the nuances of installation. Otherwise, you will have to redo the work.
Particular attention should be paid to chimney and ventilation pipes, as well as the outlet for installing the antenna.The antenna lead is cut off at the top before installation, then installed on the rack. All joints are fixed with silicone glue, and then with screws.
To remove ventilation, a neat hole is made in the tile sheet, after which silicone glue is applied to the passage element and fastened to the tile with screws.
When we cover the roof with metal tiles with our own hands, you should pay special attention to the chimney. It is necessary to ensure the tightness of the seams adjacent to it.
To do this, you can make a special apron from the inside as follows:
- Take a bar, and, leaning it against the wall, make markings on the brick.
- Poke the marked line with a grinder.
- Cut the bar in the right place and attach it with a self-tapping screw. Do this around the entire pipe.
- After inserting the edge of the apron into the gate, cover it with silicone sealant.
- Under the lower edge of the inner apron, drive a flat sheet, the so-called tie.
- Make a small rim along the edge of the tie with pliers or a hammer.
- Mount a sheet of tiles on top of the tie.
- Before you make the roof of the house with a metal tile, you should arrange an external apron. To do this, use the upper adjoining strips. Carry out their installation without leading the upper edge into the strobe, but simply attaching it to the wall.
Installation of additional elements
After finishing laying the tiles on the roof, you can proceed with the installation of additional elements. These include snow retainers, walkways, roof fencing, lightning rods.
If you do not carry out the initial installation, but cover the roof with metal tiles, then it is possible that grounding has already been installed before.If not, then you should definitely do it.
Note! Roofs of metal houses very often attract lightning, so it is important to take care of safety. In addition, household appliances powered by electricity can be damaged by lightning strikes.
If you want to know how to properly cover the roof with metal tiles, the video instruction contains all the step-by-step steps, including the installation of grounding. Typically, lightning rods are used in three types - mesh, antenna and rod. For an ordinary residential building, the last two types are more often used, and mesh ones are installed on large buildings.
On our website you can find instructions on how to properly cover the roof with metal tiles, video tutorials on this topic will tell you in detail about the work process. Do-it-yourself installation with a serious approach will cost you much less than attracting the help of workers. The process of work is not as complicated as it might seem at first glance.
By following all the rules, you will be able to cope with this work on your own. And the quality of the final result will depend only on you.
