Element of the roof is the valley. Roof: scheme and device

On a very complex roof configuration, there is usually an element such as endova. Roof, scheme the rafter system of which is designed in this way, should be isolated from precipitation and melted water as thoroughly as possible. EAn element is called a roof element that closes the junction of the two skates forming the inner corner. In such gutters, a great deal of rainwater is always drained. Therefore, when covering the roof, they should pay maximum attention.

Features of the construction of the valley

In order to avoid the leakage of the roof, the gutterSkate joints must be properly waterproofed before installing the main material. In most cases, three main elements are used to cover this important place of the roof:

• waterproofing;
• lower endowment;
• upper end.

The arrangement of a continuous crate is a procedure by which, among other things, reliability can be ensured such an item as endova. Roof scheme which assumes the presence of such elements, or rather, its frame, is assembled by a special technology.

Roofing material or special self-adhesive carpet. The latter option is considered morepreferred. A special tape costs more expensive than roofing felt, but it also protects the joint from moisture much more reliably. The upper and lower end boards usually come complete with roofing material. But sometimes they have to do independently. In this case, galvanized sheet is used, or sheets of aluminum or copper.

Features of the assembly trussing system

The relative complexity of frame assembly is what makes it different. Roof with endovy. Rafter system (scheme such design is presented below) in this case is mounted using additional elements.

Crate under the endova is usually packed after installing the main pit. At the first stage in the place of a break the rafter leg is mounted. Where it has the highest load, a rack with booms is installed.. Next, short ones are brought to the main rafter at the right angle.

At the next stage, the crate of the skates themselves is packed. To do this, use a board that is not too thick. HTo make the end of the gutter, between the elements of the already stuffed crates just additional thicknesses are installed. Thus, the gutter is usually settled under the metal tile.

Under ondulin most often mounted is slightly different endova. Roof, rafters scheme which in this case is the same as when using a metal tile, in the place of a break, sheathes are not on a continuous crate, but on two long boards laid from the ridge to the ledge. The width of these elements usually exceeds 10 cm. Lay the boards down the slope, leaving in the area of ​​the main truss foot axis joint gap 15 cm wide

How to make the lower bar for metal

This item endova is usually made of tin. The width of the continuous crates under the bar more often equal to 60 cm (30 cm on each side of the joint). Depending on the roof construction, angle, etc. this indicator may be more or less. In any case, cut from the tin bottom bar dShould be about 10 cm wider crates. In order that the flowing water does not fall on the truss system and the roofing insulation, the edges are bent on both sides at an acute angle. For the same bumpers in the future using klyimer produced fixation bottom endova to truss system.

Ondulin lower strap

Under this material, as already mentioned,settling in a slightly different endova. The roof, the scheme of which involves the use of two vertical boards as a batten, can also turn out to be quite reliable. But the bar in this case, of course, needs to be done a little differently. For its manufacture in the middle of the strip cut from the tin, the chute is curved. Its dimensions should correspond to the width of the gap between the support boards (15 cm).

Roof end roof: upper plank

This element is most often made from metalsheets coated with a polymer layer. In the selection of the last ensure that their color does not differ from the color of the roofing material. If this rule is not followed, the finished roof will look sloppy. Curved upper endova in accordance with the configuration of the angle of the junction of slopes.

Gutter Waterproofing

This procedure should be carried out as thoroughly as possible when arranging such an important element as endova. Roof scheme which assumes use under the lower level of a continuous obreshetka, usually it turns out reliable. But only if the hydraulic insulator on the gutter is mounted correctly.

Ruberoid strip to solid crate junction attach to bitumen mastic. For additional fixation when using this material can also be used nails with wide caps. They are stuffed on the upper corners of each ruberoid strip in such a way that later they will be under the lap. The width of the latter should be equal to at least 10-15 cm.

Installation of the lower and upper slats

After the waterproofing is fixed,You can start assembling the endy itself. Klyimery lower bar set at a distance equal to the pitch of the main batten. Laying strip strips begin at the bottom. Horizontal overlap between the elements, as in the installation of the waterproofing, make 15 cm.

Sheets of metal tiles are turned into a gutter so that their edges do not reach the central axis by 6-10 cm. Ondulin is preliminarily cut along the extreme lines of the gutter curved in the bottom rail. Upper end set from below. Attach it to the wave in increments of about 20 cm.

Other types of end

The tilt gutter trimming technology described above is the simplest. This is the way that work is usually done. do it yourself However, roof endovy can be sheathed in other ways. On steep slopes, for example, often arrange a closed node. When using this technique, you get the most reliable endova roof. Metal tiles in this case, it may take a little more than using open technology. The fact is that with this method of covering the gutter sheets are butt-joined.

When used as a roofingmaterials of a flexible tile usually apply the bound technology of arrangement of an endovy. In this case, the elements of the roofing material lead directly through the chute to the opposite slope.</ span </ p>
