End roof - how to do it right?

All owners of country houses want their house or cottage to look unusual, surprising others not only in appearance but also in the internal structure of the roof.

The more complex the shape of the roof, the more unusual the entire building takes on. In this case, the valley will be a key element in the construction of roofs, because the more slopes and valleys, the more complicated the configuration of the entire roof. Let's take a closer look at what a valley roof is.

What is a valley?

Considering such an element as a roof roof, it is worth saying that this is one of the most important elements of the entire roofing system, which is nothing more than the intersection of the slopes that form the gutter. Endovs are the internal (or incoming) corners of the roof, the junction of the slopes (in the form of a tray) is used to collect water.

When designing the entire roofing system, special attention should be paid to the roof valleys, since they are most susceptible to loads in the form of precipitation.

Therefore, when connecting the slopes, rather strict rules should be followed when erecting a roof roof. Materials must meet the highest quality requirements, and erection technologies must be very accurately followed.

At the same time, it does not really matter what type of roof the whole building will crown (hip, in the form of a tent, or a cruciform), in all these types of roofs there is such an element as an endova, and therefore, special attention should be paid to their construction and design.

Even the smallest mistakes in the design of the roof can lead to sad consequences: from ordinary leaks in the roof to its complete collapse if all possible loads (from wind and sedimentary) are not taken into account. Therefore, if there is any doubt in your abilities and ability, it is better to invite specialists at this stage of work.

Design features of the valley and its types

Quite often, you can see that the endova on the roof is made of metal sheets in the form of strips.

They can have their own design features. Depending on this, two types of them are distinguished - the lower endova level, the upper endova level.

The lower bar and its installation are done in cases when a negative angle is formed at the joints. Its main purpose is to prevent moisture from entering through the joints.

The installation of the lower bar must necessarily go even before the stage of installing materials for the roof, such as, for example, corrugated board or metal tile.

The upper plank of the valley, for the most part, bears only a decorative function. It should give the docking areas an attractive appearance. In other words, the installation of the valley, this is the final stage in the exterior design of the roof.

The upper level of the valley is established after the installation of roofing materials.

You need to pay attention to the place of attachment of the valley and choose it very carefully. This will eliminate damage to the bottom of the valley. For fixing, it is best to use roofing screws, and so that there are no leaks in the attachment points, it is necessary to use lining layers.

There are three main types of valley:

• open type;
• closed type;
• intertwined.

Their main differences are only in the variety of methods for joining and weaving roof slopes.

End Roof Design

In the process of designing the entire roofing system, it is necessary to understand that the more complex the shape and type of the roof, the more difficult it will subsequently be its construction.Accordingly, and vice versa, the fewer slopes, and, therefore, the whole structure is supposed to be simpler, the less difficulties there will be with its construction.

If the roof is supposed to be multi-pitched (for example, hip) and with a large number of valleys, then there must be a plan for the future roof with the calculation of the main dimensions of the building, as well as other design features.

To properly design the roof, it is necessary to break the building into rectangles, the largest of all will serve as the main room, and the rest, those smaller, will serve as extensions.

In an approximate scale and indented from the walls, you need to depict the entire perimeter of the future roof. In those places where it is supposed to connect the main room with the annexes, there will be a valley line. Such a line will be the internal angle at which the other elements of the roof converge.

Most often in modern houses, you can see the roof roofs, which are made in the form of the letter T. In this type of roof, there are no differences between the different types of rafters (diagonal and roof).

In this case, we can say the following: both the installation of the endows, and all other stages of the work can be done in exactly the same way as the installation of ordinary rafters. But in this case, special attention should be paid to the correct connection of the ramps and their reliable fastening to each other.

Laying groove

Before you start laying the groove, you need to take care of laying the wooden flooring. For this purpose, you can use a trim board. However, it is worth remembering that it must be treated with special antiseptics.

On multi-pitched roofs, it is impossible to do without an endow, and therefore both the roof and the endow become almost uniform concepts. When laying the groove, you must pay attention to the following features:

1. it is worth remembering that the groove is installed before the arrangement of the crate;
2. after the groove is laid, the edges of the crate must be fixed to the flooring;
3. all ends of the timber used should be suitable for flanging the groove;
4. in the process of laying the groove, its angle should be bent a little more than the angle of the valley itself;
5. all installation should be carried out from the cornice and in the direction from bottom to top;
6. to fix the groove to the flooring, it is necessary to use special roofing nails;
7. if it is necessary to build several grooves, then the minimum overlap should be about 10 centimeters;
8. ribs running across should be aligned during installation;
9. both edges of the groove, providing the best water-repellent properties, must be glued with a strip of foam rubber, it will provide reliable protection of the entire valley from the penetration of excess snow, dirt and water into the roofing material.

In the process of fixing the endow groove, you need to constantly pay attention to ensure that it does not shift.

Weather Protection

Since the endova is one of the most vulnerable elements in the entire structure of the roof, it is natural that it should be as well protected as possible from the influence of weather conditions. To achieve these goals, you can use special roll carpets for valley.

With a slight slope of the roof, you can do with a coating of 4 layers. But it is necessary to connect the previous three layers together. The upper layers are fixed in one row with the canvas on the slopes.

With a slope slope of more than 15 degrees, all three layers also adhere to each other, but with a certain level of conjugation in the slope of the valley.

The groove, whose width is less than 60 centimeters, should be covered with long carpets, and if it is even wider, then pieces of roll coatings can be used. Laying of all layers must be carried out transverse to the whole valley.

End roofs are, first of all, complex types of roofs. The aesthetic appeal and beauty of the whole house, in general, and the roof, in particular, depend on such an element as endova.

Therefore, you need to make sure that at every stage of the work, everything you have in mind is done as accurately and reliably as possible, in accordance with the developed drawings and plans. And only if all the conditions and requirements for the construction of an end roof are met, your non-standard roof will please you and your friends with its unique forms and beauty for many years!
