Metal tiling step by step

The installation of metal roofing will allow to build a reliable and durable roof for the house.

The work process can be considered simple even for a beginner roofer, as the material used is lightweight and easy to install.

At the moment, preference is given to building products of domestic production.

For example, among the roofing materials, the attention of consumers was won by the metal tile Grand Line.

Building products of the company Grand Line are distinguished by an acceptable price category, high performance characteristics and a variety of shades.

Using roofing materials and additional elements of the Grand Line, as well as observing the rules of laying a metal roof, you can step by step erect any type of roof - a broken mansard, simple gable, hip or ordinary four-slope.

As experts note, the most difficult moment in roofing works is the installation of the skeleton of the battens and the laying of heat and waterproofing.

We hope that the step-by-step instruction and video material on the laying of metal tiles will help us to ease the construction process a little.

Installation instructions for metal tiles

To lay the metal tile with your own hands on the roof of the house was successful and was receiveda qualitative result, you need to know the correct sequence of actions.

Complete instructions for the installation of metal tiles includes more than 10 items of work that need to be done step by step:

1. Calculate the amount of material required( rafters, fasteners, the amount of waterproofing, thermal insulation, etc.);
2. Installation of rafters and skeleton of the battens;
3. The curtain rod is installed - for the subsequent arrangement of gutters;
4. The frontal board is mounted, the roof overhangs are sewn;
5. Holders under the gutter gutter are attached;
6. The layer of waterproofing is laid. Along the rafters is fixed counter-lathing;
7. To add rigidity to the roof structure, install additional boards;
8. A curtain rod is being constructed, equipage is being arranged;
9. Assemble chimney aprons. Lay a layer of vapor barrier - ruberoid. Also, as a vapor barrier, not only roofing material, but also pergamine can be used;
10. Under the rafters are mounted counter-strips, laying heat insulation;
11. Mount metal, perform the design of mansard and inspection apertures;
12. Execute the decoration of the upper valley;
13. Conducting the installation of adjacent rails, fix the ridge bar;
14. Make a roofing fence and build transitional bridges;
15. Gutters are installed on the roof along the perimeter.

How to calculate the amount of material?

Metal shingles are produced in the form of steel sheets, their appearance simulates overlapping small fragments of the shingles.

There is a full and working or useful width of the sheets, the dimensions of the full size exceed the working dimensions by 8-12 cm. It is said that this fact should be taken into account when calculating the material.

Horizontally the required number of sheets allows you to define the following scheme: the length of the sheet of roofing material is divided by the size of its working width. Further, the resulting number is rounded up.

For the future length of the row of metal tiles, the following scheme is taken: the length of the roof slope is measured( from the cornice to the ridge beam), 15 cm( the overlap value) is added to the resulting number, plus the value of the eaves.

Today, the market offers a metal tile with a length of sheets from 700 mm to 1200 mm.

If necessary, the dimensions of the sheets can be increased to 4000-4500 mm, which will make their laying more convenient.

Places of butt joints of sheets between skates are made so that when laying metal tiles overlap the bevels.

The length of the items is selected, taking into account that the cut edge does not fall under the step or wave sheet.

If two sheets are laid for one row, then the bottom sheet should be 15 cm longer to create an overlap.

Features of the installation of rafters for laying the metal tile

For the construction of the roof rafter, 100x50 mm or 150x50 mm beams are used. The step between the elements of the rafters should not exceed 900 mm and be less than 600 mm.

If it is necessary to increase the pitch, it is recommended to additionally mount the beams on the lathing, which will eliminate the sagging of the metal tiles.

For the construction of rafters and the skeleton of the battens, only well-dried wood is taken, otherwise the wood will turn under the influence of heat.

In addition, all the wooden building material is treated with antiseptic compounds.

Primer will protect wood from decay and prolong the service life of the roof.

To ensure that the rafter system is not skewed, the angles and length of the skates are determined, and then the boards are adjusted to the required dimensions.

After the rafters are mounted, a cornice board is installed, due to which the structure receives additional strength.

The next step is the fastening of the frontal board, it also gives the rafters rigidity, and are fixed with the help of nails to the end of the rafter. Overhangs of the roof are covered, using a lining or soffits.

During the construction of roof rafters, it is necessary to provide ventilation under the roof.

If an unperforated filing is used, then it is necessary to make several holes in each rafter board. Then the lining is primed with an antiseptic compound and varnished.

While installing the holders under the gutters, the hooks are fixed on the cornice board or rafters.

To do this, pre-cut the wood in the wood, where the legs of the holders are installed, then each of them is bent and fixed with screws.

If the order is violated, and the mounting of the holders is carried out after the laying of the tile sheets, they are recommended to be fixed on the frontal board.

Installation instructions for roofing cake for metal tiles

It is impossible to build a quality roof and make the correct laying of metal tiles without laying the interlayers of waterproofing, heat-insulating and vapor-insulating material.

To prepare the load-bearing structure for laying the finishing roofing, the following work is carried out:

Steam insulation

On the inner side of the rafter, a vapor barrier is used, usually a ruberoid is used. The functional purpose of the material is to hold the steam.

The ruberoid becomes a barrier to moist air rising from the room to the attic, and prevents it from penetrating into the insulation.

Video:

If you skip this step, the condensate will settle directly on the insulation, due to which the insulation will be rotted.

As the cardboard-based felt is rapidly losing its technical properties, the construction market offers its analogue based on polyester.

The ruberoid of this type has good elasticity and higher resistance to external factors.

Thermal insulation

After the roofing material is laid, one or several layers of insulation are placed on top of the roof from above. The number of layers depends on the type of thermal insulation and the climate of the region.

Warming can be carried out and before the roofing material is laid, then the insulation can be made from inside the rafter system, which is very convenient.

In another case, the thermal insulation must be mounted from the outside of the roof.

Waterproofing

For buildings built for auxiliary purposes, insulation is not required. But here to avoid leaks, you have to take care of the waterproofing of the structure.

The film for the waterproofing of building elements has the property of passing steam through itself and not letting the moisture back in.

The existing waterproofing material is divided into several types: anticondensate, classical and diffusive.

The first type of waterproofing has a fleecy surface that collects moisture and prevents it from draining. As soon as the air becomes dry, the moisture evaporates. With its arrangement make a two-circuit ventilation.

For the classic type of waterproofing, it also provides for two-level ventilation.

Video:

One gap of at least 3-5 cm is made between waterproofing and metal, the second - between the heater and the layer of waterproofing.

Diffusion film - its device requires a single-circuit ventilation, a gap of 3-5 cm is made between the moisture barrier layer and the tile. The film is pulled over the heater.

Assembling the tiling for metal tiling

The technology of laying the tile provides for the pre-installation of the planking over the waterproofing layer.

The installation instructions for the battens may differ, since the way it is mounted depends on the roofing materials used.

The way of mounting the skeleton of the battens:

• The counter-crate is made - for its manufacture a bar of 30x50 mm is used, which is fixed to the rafter legs. Its purpose is to organize the gaps between waterproofing, crates and roofing;
• Next, using a board or bars with a cross-section of 50x50 mm or 60x60 mm, the skeleton of the crate is made. The installation is carried out on top of the counterbrush and parallel to the cornice board, the step between them depends on the dimensions of the roofing sheets.

Following the order of work, do not forget about the device of the apron around the ventilation and chimney pipes.

This step is necessary to ensure tightness in the place where these structural elements are located.

First of all, the apron is made from the inside of the structure, and after laying the metal tile, its exterior is executed.

More detailed acquaintance with the arrangement of the roofing under the roof will allow the following video material.

Features of metal tiling

It is better to lay the metal tile on a rectangular inclined surface with the lower edge of the ramp - this may be the left corner.

The first sheet of the product is baited on the lower bar of the rafter.

Temporary fastening will allow later to straighten this sheet if there is a mismatch when laying the subsequent products. But it is better to lay out the first sheet using a level.

Next, the subsequent sheets are overlapped. The order of laying all the rows is from the bottom edge to the ridge beam.

Screws are screwed lower by 1.5 cm of the stamping line, between the waves, in the areas where the beam of the crate is present.

When installing from the lower edge of the ramp, it is recommended to use the longest products, which will reduce the overall load on the roof.

In this case, do not leave the roof cornice open, since from the roof directly onto it will be rain water. To avoid this, it will be sufficient to perform a descent of the roof 40 mm down.

To complement the above material on the theme of laying a metal tile will allow a thematic video.
