Laying metal step by step

Laying metal step by step

Stacking metal will allow to build a reliable and durable roof for your home.

workflow can be considered simple, even for novice roofer, since the material used is characterized by light weight and ease of installation.

Currently increasingly favored construction products produced domestically.

For example, among roofing materials has gained the attention of consumers metal Grand Line.

Building products company Grand Line differ affordable price category, high-performance and a variety of shades.

Using roofing and flashings Grand Line, as well as observing the rules of metal styling, you can step by step to build any type of roof - a roof broken line, a simple gable, gambrel or hipped usual.

According to experts, the most difficult moment in the roofing assembly is considered to be the frame battens and laying of heat and waterproofing.

hope that a little easier building process will enable the steps below and video material on the installation of metal.

Installation instructions metal

to

stacking of metal with their hands on the roof of the house was successful and qualitative results were obtained, it is necessary to know the correct sequence of actions.

Complete instructions for installation of metal includes more than 10 items of work that must be done step by step:

  1. calculates the volume of material required (stropilovka, fasteners, the number of waterproofing, thermal insulation and so on.);
  2. Held assembly of rafters and frame crates;
  3. Set Cornice strip - for the subsequent installation of sewers;
  4. mounted frontal board, filing is performed eaves;
  5. Fasten holders under the gutters gutters;
  6. Implemented by laying a waterproofing layer.Along the rafters fixed counter-lathing;
  7. To make the roof structure rigidity mount additional boards;
  8. constructs Cornice strip, settling flagon;
  9. install on aprons for chimneys.Lay vapor barrier - roofing material.Just as a vapor barrier can be applied not only roofing material, and asphalt;
  10. Under stropilovku mounted counter-strips, paving the insulation;
  11. Mount metal roofing, roof design is carried out and inspection openings;
  12. Carry out design of the upper valley;
  13. install on adjacent rails, fix the ridge beam;
  14. Make a roof railing and constructing catwalks;
  15. On the roof drains installed around the perimeter.

How to calculate the amount of material?

metal tiles are produced in the form of sheets of steel, their appearance simulates laid overlapping small fragments of tiles.

There is a complete and working or usable width of sheets, size Full size exceeds 8-12 cm size working.It is said that to the calculation of the material, this fact was taken into account.

Horizontal desired number of sheets to determine the following scheme: the length of a sheet of roofing material divided by the size of its working width.Next, the resulting number is rounded.

Driving roofing pie

for the future length of the row of metal taken such a scheme: the measurement is the length of the slope of the roof (from the eaves to the ridge batten strips), the resulting number is added to 15 cm (size of overlaps), plus the value of the eaves.

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

If it is necessary, the size of sheets can be increased up to 4000-4500 mm, which allows them to make a more comfortable styling.

Places butt joints between sheets of ramps is performed so that when laying metal overlaps the bevels.

length product is chosen, given that the cut edge does not lay down a notch or corrugation crest.

If two sheets, the bottom sheet should have a length of 15 cm longer for the organization are stacked to overlap one row.

Features rafters installation for laying metal

stropilovki For the construction of the roof beams are used 100x50 mm or 150h50 mm.Step stropilovki between elements should not exceed 900 mm and be less than 600 mm.

If you want to increase the step, it is recommended to carry out further installation of the boards on the crate that will eliminate sagging sheet metal.

For the construction of rafters and frame crates taken only well-dried wood, otherwise under the influence of heat, wagged his tree.

Moreover, the whole wooden construction material is treated with antiseptic compositions.

Primer allow protect the wood from rotting and prolong the lifespan of the roof.

To subsequently truss system is not twisted, determine the angles and the length of the rays, and then customize the board to the required size.

After stropilovka mounted, set eaves board, whereby the construction obtains additional strength.

next step - fixing the front of the board, it also gives stropilovke rigidity and fixed with nails to the end stropilovki.Eaves sheathe using battens or soffits.

stropilovki During the construction of the roof is necessary to ensure ventilation under the roof.

If you use non-perforated filing, then we need to make a few holes in each rafter board.Then primed trim antiseptic composition and varnish.

During installation holders under the gutters, hooks fixed on the eaves board or rafters.

To do this in the wood doing a pre-grooves, which are set holders feet, then each of them is bent and is fixed with screws.

If the order is broken, and the installation of holders is carried out after laying tile sheets, they are recommended to be mounted on the front board.

Installation Instructions under the metal roofing pie

To build a quality roof and make a correct folding of metal is not possible without stacking layers of waterproofing, thermal insulation and vapor barrier material.

To prepare the support structure for laying finishing roofing, spend the next number of works:

Vapor

From inside the truss construction equip vapor barrier, as it is usually used roofing material.The function of the material lies in the retention of steam.

Ruberoid becomes a barrier to the moist air rising from the room to the attic, and does not allow him to penetrate the insulation.

If you skip this step, the condensate will fall directly on a heater, whereby the insulation undergo decay.

As roofing material on a cardboard base quickly loses its technical properties, the construction market offers its counterpart made on the basis of polyester.

Roofing material of this type has good elasticity and a higher resistance to external factors.

insulation

After the roofing material is laid on top of it from the outside of the roof lay one or more layers of insulation.The number of layers depends on the type of insulation and climate region.

Warming can be carried out and before the laid roofing material, then the installation of insulation can be done from inside the truss system, which is very convenient.In another

insulation case to mount on the outside of the roof.

Waterproofing

For buildings constructed in the auxiliary purposes, insulation need not be applied.But in order to avoid leaks, it is necessary to take care of the construction waterproofing.

film for waterproofing of building elements has the property to pass through a pair out and keep out moisture back.

existing waterproofing material is divided into several types: anti-condensation, and classical diffusion.

first type of waterproofing has a fuzzy surface, which collects moisture and prevents it from draining.As soon as the air becomes dry, the moisture evaporates.In its arrangement make the dual-circuit ventilation.

for classical waterproofing type with its two-tier device, also provide ventilation.

Video:

A gap of at least 3-5 cm is made between the waterproofing and metal tile, the second - between the insulation and waterproofing layer.

diffusion film - it requires a single-ventilation device, a gap of 3-5 cm between doing a moisture layer and the tiles.The film is tensioned by a heater.

Mounting battens under the metal

metal stacking technology provides pre-installation of the waterproofing layer on top of the crates.

Installation instructions crates may be different, as a way to mount it depends on the use of roofing products.

method mount batten carcass:

  • done counter-lathing - for its production are used 30x50 mm board, which is fixed to the rafters.His appointment is the ability to organize the gaps between the waterproofing and roofing battens;
  • Next, using planks or boards with a cross section 50x50 mm or 60x60 mm make the frame crates.Installation is carried out over the counter-batten and parallel to the eaves board, step between them depends on the roofing sheet sizes.

the procedure of work, we should not forget about the apron around the unit and ventilation chimneys.

This step is necessary to ensure the integrity of a place where these structural elements are placed.

primarily apron is made from the inner part of the structure, and it is performed after the metal exterior design styling.

Features stacking metal

Laying on a rectangular metal inclined surface is better to start from the bottom edge of the slope - this may be the left corner.

first sheet products baits on the bottom bar of truss construction.

Temporary fixation will allow later to trim the sheet, if there is a mismatch when installing subsequent articles.But best of laying the first sheet align with the level.

Then, the installation of the following sheets overlap.The order of stacking all series comes from the bottom edge to the ridge beam.

Screws screwed down 1.5 cm stamping line, between the waves, in areas where there is timber battens.

By stacking from the bottom of a slope, it is recommended to use the best long products, which will reduce the overall load on the roof.

We should not leave the eaves of the roof open, as from the roof straight at him will fall the rainwater.To avoid this, it is enough to perform a roof slope of 40 mm down.

supplement the above material on stacking of metal will allow thematic video.
