How to strengthen the decking on the roof

As practice shows, to build a country house ─dovolno expensive hobby.In order to reduce costs, many owners decide to cover the roof built with his own hands.Recently recognized as an extremely popular use of profiled sheet for roofing arrangement.

Survey characteristics proflist

By definition, profiled is a universal construction raw materials.Such articles are covered by a roof, get off the walls, floors, of which built temporary and permanent fencing.They have undeniable positives, ─ reliability, durability, ecological compatibility and durability.Profiled sheets do not require periodic painting, because corrugated board is not afraid of sunlight.

In the manufacture of sheeting is galvanized steel, which is applied to the surface of the polymer coating, making the product becomes like a slate.Today's building materials market offers potential buyers a wide range of types profnastilnyh sheets.They are:

  • have different dimensions;
  • have good corrosion resistance, rigidity and strength.

To create the roof, use the web profile with special groove through which moisture is given.Given the potential operational, wind, snow loads, it is possible to make engineering calculations and results-based decking select the required thickness.

Variety of corrugated board

Species corrugated

Any home owner wants, that laid the roof, over the years, has served faithfully for his master, delighting the eye.In light of this, particular attention is paid to the climatic characteristics of the region.Where there is an increased winter snow, it is advisable to opt for a steel sheet with a high flexi hose.

Basic rules mount corrugated roofing sheets

In the process of mounting a profiled material, like other specialized coatings, laid partial overlapping webs, whose value is determined by the overall slope angle of inclination.

order to correctly lay sheeting on the roof, you must adhere to the following guidelines:

  • if the roof slope less than 14 °, the plates are attached to the horizontal overlap of about 20 cm;
  • optimum overlap is from 15 to 20 cm (tilt roof in the range from 15 to 30 °);
  • when the slope of the roof is more than 30 °, pad size is estimated at 10-15 cm.

In some cases, all of a plurality of longitudinal and transverse joints it is advisable additionally to "grab" with silicone or sealant Thiokol.

matter how difficult and steep ramp may have been, the web should be clearly laid parallel to the eaves.Last aligned precisely horizontally.Accuracy is monitored overhang.Blades of adjacent sheets are fixed with a screw.At the same time, it rules out the possibility that the decorative and protective layer is broken.

Before installing profnastilnyh sheets on the roof dimensions are measured eave defined profile height.Sections are fixed on the roof of the plane with the help of samonorezayuschihsya screws (screws).For more isolated hardware is complemented by rubber sealing washers.Top horse fastened with screws through the top "corrugations".

Construction insulation on roofs profnastilnyh

While the building is operated, the condensate will be formed under the roof.So that moisture does not accumulate there, the roof is constructed in such a way that the temperature behavior inside and outside of the same.This is achieved by proper installation of special heat-insulating and structural elements paroizoliruyuschih and system that ensures proper ventilation space.

order to extend the roof life, prior to installation is laying, which does not accumulate condensate.The best option is the use of steam waterproofing membrane.Planting the latter starts from the eaves towards the ridge.For fixing membranes suited nails with a large hat.

pieces waterproofing film stacked overlap.Thus, binding mezhstropilny sag material of a few centimeters size.Overlap joints are fixed using adhesive tape.

In the upper part are equipped with counter-rafters, which are designed to protect the membrane from damage during mounting sections.Where converge pad and the first board should be provided with air flow.Equip vents, koi are located closer to the ridge.

to air out properly assembled the necessary elements:

  • channels for ventilation;
  • specific intervals separating the roof slab and the horse;
  • ventilation grilles that developing are at the ends of the buildings.
Installation of under-roof insulation

Installing insulation underlay

When developing are ventilation gaps in the fabric waterproofing membrane hoisting set of wooden slats, which help remove excess moisture and condensation.Each unit must be securely fixed.

As mounted on the roof decking

When mounting profile should take into account one thing: the sheet must be positioned so that the edge of the last took place not on the basin and on the top.In turn, the capillary grooves must extend to the outer edge.Raising the roof material is carried on logs long cables.

Corrugated stacked cross belts, and on the first row is added to the allowance of 10-15 cm. Blades secured by roofing screws, hexagon head which works in tandem with the sealing rubber gasket.When screwing it must be ensured that the screws are strictly at right angles, without the possible distortions.Screws will not be released if the color will match the shade profnastilnyh sheets.Sections are fixed on the edges of the canvas, in the middle, and in places of connections.In other words, for every leaf leaves 6 screws.

The sequence of mounting metal sheets

following belt mounted trapezoidal sheet with a 10 cm overlap.Thus, the stacking is carried up to the ridge.In the same way laid and the second ramp.

To cover the roof ridge using conventional galvanized strip (with a width of 40-50 cm), or a special shaped sheet, fastened with screws.

Upon completion of installation work of the roof surface is cleaned of chips and dust, scratches and cuts should be carefully touch up, so as not developed a bead corrosion.After three months, it is advisable to tighten the screws as fasteners for wooden parts may, over time, weaken.

What not to do when working with profiled sheet

There are some restrictions that should be considered when construction and installation works related to the laying of the roof made of profiled sheet.So:

  • - should not attempt to fix profiled sheets with nails, because there is a risk that they may be ripped off by strong gusts of wind;
  • - steel sheet can not be processed by flame cutting, welding and joining.

strictly forbidden to produce cutting corrugated board using the "grinder" because high temperatures can lead to degradation of polymer coatings (such as zinc).As a result, it can rapidly develop rapid corrosion.Scissors for metal, may only be slitting sheets.

If the profiled webs have to share, you have to use blanking Electroscissors or jigsaw.
