How to cover a roof with roofing material: preparation of bituminous mastic, coating subtleties and repair of roofing material from roofing material

Many developers of country houses cannot afford to purchase expensive roofing materials. Therefore, more and more often they return to the old, time-tested material - roofing material. Moreover, the term of the roofing material is not so short - 15 years. In our article, we will talk about how to cover the roof with roofing material in order to avoid mistakes and perform a high-quality and reliable coating.

Before starting work, first calculate the expected load on mansard roof truss structure, For example.

If you understand that it is too weak, it makes sense to strengthen it or use fewer layers of roofing material.

Although the first option is preferable, since the reduction of roofing material layers will affect the reliability and quality of the roofing.

So, we decided - we cover the roof with roofing material. If you have a new building, then take care of the construction of the crate.

To do this, we recommend using dry edged boards, it is desirable that they have an equal thickness of -30 cm or more. Too thin boards will not be able to withstand a high load, especially in the winter season, when the snow "cap" will cover the roof.

Important: lay the boards on the crate tightly enough, carefully adjusting to each other, leaving no gaps. Although many are limited to a step of 10-15 cm. We are not supporters of this technique. It is better when the crate is made continuous, this will protect against premature leakage and failure of the roof.

One more piece of advice: when calculating the amount of roofing material, do not forget to take into account that you need to overlap the side and butt overlap by at least 10 cm. And when finishing the ridge with roofing material, even more - the overlap should be at least 25 cm.

The basic basics of roofing with roofing material

Further, our story is about how to properly cover the roof with roofing material. In order for the roof to be of high quality and reliable, it is necessary to remove all the filling from the sheets of roofing material.This operation can be performed using only mechanical cleaning methods, or you can moisten the entire surface with diesel fuel.

When laying a roof with roofing material, it is important to take into account its slope. So, if the roof slope is 15 degrees, then it is enough to lay the roofing material in two layers. If the roof slope is less than 15 degrees, then to ensure reliability, we recommend laying the roofing material in three layers.

Not so long ago, bitumen was used for gluing and gluing roofing material. We recommend using bituminous mastics.

The main advantages of bituminous mastics:

• at low winter temperatures, mastics are less fragile;
• have increased heat resistance.

How to prepare bituminous mastic on your own?

A roofing felt roof will last for more than one year, subject to all the technological processes of its laying. Consider the technology for preparing bituminous mastic at home.

The main steps in the preparation of bituminous mastic:

1. One of the fillers must be added to hot bitumen. It can be: peat chips, flour, small sawdust, ground chalk and about 6-7 varieties of asbestos.
2. It is important to know that any filler must first be sifted through a sieve and dried.
3. In order to get 10 kg of high-quality bituminous mastic, you need to take 1.5 kg of filler and 8 kg of bitumen.
4. Load the bitumen into the container, but not to the edges. We take into account that after we will add the filler, and it will be much more convenient to interfere.
5. To stir and remove the pollution foam that appears after the bitumen boils, we recommend making such a device: nail a tin can onto a wooden stick.
6. It is necessary to heat the bitumen until the moment when the foam stops rising.
7. While stirring the boiled bitumen, add the filler.
8. Mix and pour any used oil.
9. Important: bituminous mastic should be used only when hot. After cooling, it loses its characteristics and properties, it needs to be heated again.
10. Do not neglect the safety rules when working with hot material.

After the roofing material has been laid on the roof, fill it with a thick layer of hot bituminous mastic and do not forget to sprinkle with coarse sand. This measure not only helps to strengthen the roof, but also significantly extends its life.

The main subtleties of laying euroroofing material

Despite the outward lightness, putting roofing material on a concrete roof is not so easy. To do this, you need to know that not only does the base need to be clean and dry, it also needs to be cleaned of natural contaminants (moss) and resin.

In order to find out how to properly cover the roof with roofing felt, you can seek advice from specialists. They will definitely prompt and help calculate the required amount of material, as well as help determine the number of layers.

So, the minimum number is two layers. The first layer is called bedding, it can be laid without sprinkling.

As a second layer, we recommend using a modern material - euroroofing material. Typically, manufacturers supply this roofing material complete with granite dressing.

For ease of use, we recommend that you first cut the roofing material into sheets with the required length. After that, we cover a certain part of the roof with bituminous mastic, heat it up with a special gas burner and lay euroruberoid.

The main subtleties of roofing with euroroofing material

Here are some useful tips: how to cover the roof with euroruberoid:

Important! The top film of euroroofing material is an indicator of temperature. After the film turns white and burns, you can start laying euroroofing material. Do not overheat euroruberoid sheets, otherwise they will completely melt and lose their quality characteristics.

1. Spread the roof area with bituminous mastic and heat it with a gas burner.
2. Lay roofing material and roll a special skating rink. Such a roller can be used on roofs with a flat surface.
3. If you do not treat the surface with such a roller, then there may be parts where air remains. Subsequently, condensate will accumulate here and gradually this area will become unusable, it will need to be repaired.
4. A roofing felt roof will only be made with high quality when there are no "pockets" with air.
5. If it’s impossible to remove air from such pockets, then you need to use a soft device (it can be a roll of rags), tapping, to attach the roofing felt to the base of the roof.
6. Some specialists lay the reinforcing mesh on the mastic. This measure allows the roofing material not to slip during gluing and ensures its tighter fit to the roof base.

The cosiness and comfort in the house depends on how to close the roof with roofing material.

Therefore, experts are unanimous in their opinion that it is necessary to fulfill the following requirements:

1. Lay the roofing material on gable roof only possible in warm and dry weather.
2. For the convenience of performing work, measure and cut sheets of roofing material in advance.
3. In the event that the roofing material does not fit snugly enough to the base, it must be additionally fixed with a rail.
4. The laid sheet of roofing felt should not have folds in the device of such a design as shed roofing from corrugated board. This will subsequently lead to deformation of the roofing, up to its destruction.
5. The edges of the roofing material must be wrapped under the base of the roof by 20 cm. Thus, you will ensure reliable tightness and protection from moisture.

Rules for repairing roofing from roofing material

If the general requirements and technologies for installing a roofing material from roofing material are not observed, defects in the form of cracks and bubbles often appear on the roof.

If you do not repair the roof from roofing felt in time, then you will subsequently have to make its overhaul, and these are completely different financial expenses.

In order to delay the onset of a major overhaul of the roof, we recommend that cracks and bubbles be identified and removed in a timely manner.

To correct these defects, you will also have to use bituminous mastic.

The sequence of partial repairs:

1. It is necessary to sweep away all the gravel that has crumbled around the edges of the damage with a dry brush. We recommend using a special building hair dryer. A hair dryer will also allow you to deal with natural dirt in the form of moss, other solid particles and dirt much faster.
2. Raise the edges of the defect; for convenience, a cross-shaped incision can be made in the center of the defect.
3. Clean and dry the area where the crack or bubble is located.
4. Apply a layer of heated mastic to the exposed areas of the roof and press the edges firmly.
5. In order for the edges of the crack or bubble to fit and stick as tightly as possible, we recommend using a wallpaper roller.
6. In the event that the edges of the defect do not converge, we recommend using a waterproofing tape or a reinforcing polyester patch.
7. It is possible to eliminate a leak in the roof even in wet weather. To do this, you need to use aerosol compositions for repairing roofs. Instructions for their use are usually written on the packaging.
8. In case of damage to a particularly vulnerable spot of the roof - the connection between the wall of the house and the edge of the flat roof, we recommend using a lead apron. It must be attached with cement mortar on the wall between rows of brickwork.

We hope that our advice and tips will help you cope with even the most difficult task of waterproofing roof corners from roofing material.
