The roof coating ondulin is one of the most sought -led services. This is due to a convenient form of sheets of material and its light weight. Being in fact bitumen material, Ondulin does not carry additional load on the foundation and walls of the house. Its installation can be even for those who do not have special knowledge in this industry.

Dimensions and Benefits of Material

The main technical characteristics of the Ontulin sheet are:

• length - 2 m;
• width - 0.96 m;
• thickness - 3 mm;
• mass - 6.5 kg.

In addition to the above positive properties, the material has:

• resistant to temperature differences;
• fire safety;
• long operational period;
• a wide variety of color solutions;
• attractive appearance.

Yes, and the cost of covering the roof of Ondulin is a serious argument to use exactly this material. In most cases, the price is formed from such main components:

• the area of \u200b\u200bthe design;
• features of the roof structure;
• creating a new crate and rafters;
• installations of the drainage system;
• work time limits;
• image of specialists.

Now the cost of covering the roof of Ondulin with the involvement of specialists is from 20 to 35 dollars. / 1 \u200b\u200bm². Therefore, it is better to carry out roofing work yourself. They will cost a maximum of 9-10 dollars. / 1 \u200b\u200bm². Moreover, there will be no special tools to fulfill work. To cut the sheets, we need a conventional hacksaw, for fastening - hammer and nails.

Stages of roofing work

In the process of fastening ondulin, naughters should be given. First, their synthetic heads have another shape than ordinary nails. Secondly, one sheet is nailed with 20 nails. Otherwise, there is no guarantee for creating a high-quality roof.

There are still such rules for using nails when installing Ondulina:

• nails are attached to the penultimate and second wave;
• checked correctness of the location of the sheet;
• the final fastening of the sheet is carried out;
• putting the nails is made at the ends of each ridge and through one to the frame;
• nails are stationed strictly in a vertical position;
• their removal is carried out by a nail with a mandatory lining of the bar;
• hardulin leaf scored by nails should not vibrate.

Ondulin roof coating technology includes the following main stages:

• processing of antiseptic structures of wood;
• creating a crate;
• laying insulation;
• waterproofing work;
• marking and installation of sheets;
• the device of cornices and skates.

In the presence of a fragile surface, screws are used for reliable fastening of the crate. When creating a frame, a place is left for ventilation holes. The thickness of the crate must correspond to the bending of Ondulin.

The fastening step and ondulin depend on the level of the roof level. In particular, when tilting the roof:

• 5-10º Creation of a solid frame from boards (plywood or OSB) with an adhesive roofing material in 30 cm;
• 10-15º - with a pitch of the lattice in 45 cm and the adhesive 20 cm;
• over 15º - respectively 60 cm and 17 cm.

When installing ondulin, attention should also be paid to the direction of the wind, which prevails in this area. First, the roof is laid on Ondulin on a skate, which is located in the opposite side of the frequent busting of the wind.

When three rows of Ondulin are stacked, half the first sheet is placed in the middle part of the roof. This will subsequently facilitate the work on the installation of the rest of the sheets. And three sheets will come into contact at the joints. Despite the fact that the ondulin includes cellulose, the material of the lattop is prohibited. Temperature differences will lead to a disruption of the roofing tightness.

Creating cornice, skates and ventilation

The cornice device provides:

• filling the ventilation comb;
• installation of gutter for water drain.

Ontulin must perform at 7 cm.

Fixing the skate is carried out after full laying of roofing material. Its fastening is carried out to each ridge of Ondulina. Nails or self-tapping screws are used (if there are metal elements). The skate bar is fastened with an overlap at 10 cm.

In the presence of a non-standard roof, besides the mounting of the planks, all the jokes will have to be sealing with silicone sealant. For lining of lateral joints apply to endands. Their installation is carried out on an additionally made crate.

An integral element of any roof is ventilation. Creating high-quality ventilation will prevent:

• overheating at the summer time;
• the appearance of condensate in winter days;
• negative condition of roofing material.

On the Ondulin Roof, the ventilation system is presented:

• several holes in its upper part;
• grid for air output at the end of the attic room;
• space between the skate and the roof;
• additional fans (if necessary).

To simultaneously save heat and create efficient ventilation, you need to use special films. They fit between:

• heat insulating and internal finishing material;
• insulation and roofing material.

Fastening of films is carried out using nails. Seeling the rest of the slots is made by self-adhesive ribbon.

Serious care for the roof of Ondulina will not need. The main thing is to clean it from the leaves. If there is a desire, you can paint the roof when a few years later she will lose its initial brightness.
