Ends is an important structural element of the roof

Endova is a trough designed to divert water running down the slopes in the places of their junction. Many people would like to know how to make and mount it. Indeed, today, when the appearance of buildings is given special attention, the roofs often have a very complex shape.

Of what can be manufactured

Endova is a very important structural element of the roof. Therefore, special requirements are imposed on the material used for its production. Of course, he, first of all, should not let the water pass. Strength, corrosion resistance and durability are also important in this case. That's why experts do not recommend using for the device ends metal plastic or polyvinyl chloride. These materials are easy to install, but they are unlikely to last too long. Usually, the galvanized sheet is used for making the ends. In many old houses one can also see this element made of corrugated cardboard.

Today, very often metal plates are used to make the ends. The valley structure, made of them, is somewhat more complicated than the conventional one. Lower, in fact, draws water from the roof. It is usually mounted if the joint has a negative angle. The upper valley is for the most part a decorative element of the roof.

Purpose and types of trends

Endova is an element by which not only water flows down, but snow rolls down. As a result, the material used to skin the stingrays does not deteriorate, and the roof itself does not leak. In modern construction there are only three basic types of trends: closed, bound and open.

Roofing system

In the event that the lath of the roof is made continuous, the trough is laid on the additional fixed strips. In this case the bottom of the valley is lined with a special thermal film. If the crate is not solid and covered with a membrane, then fill the boards in such a way that the width of the resulting support from each side of the ramp is equal to approximately 35 cm. At the same time, a tape from the membrane is laid along the gutter, onto which the main membrane is applied. Connect them using double-sided tape. Under counterlats, put a sealing tape and fix them.

Mounting of the valley

Tin, intended for upholstery upholstery, should be matched to the color of the main material used for the roofing. The sheets are connected in a way to the overlay. The width of the overlap should be at least twenty centimeters. Very often the hardness of the valley is fixed to the roof using self-tapping screws. This is permissible, but undesirable. In the place of fastenings in this case, water will fall, which will shorten the life of the gutter and the roof itself. Endowa is a very important element, and therefore it will be best to secure and secure it with special staples.

The top of the gutter is cut along the ridge from above and along the edge of the roof from below. In this case it is necessary to leave protrusions of 10 cm for folding. The connection points of the valley with the slopes must be sealed using a self-adhesive tape. Under the roof is installed a drain pipe. The width of the chute depends mainly on its length. For a four-meter valley, 25 cm on both slopes will suffice. In the event that the chute consists of several elements, their installation must begin from the bottom. The overlap of the horizontal joints in this case should be at least 10 cm.

How to fix roofing material to the bottom roof

Metal profiles or metal tiles at the junctions are cut from top to bottom so that the edges of the sheets do not reach the axis of the valley about ten centimeters. For their fastening, use clamps or self-tapping screws. The latter are screwed at a distance of at least 25 cm from the axis of the trough. When installing the profiled sheet, the step between the screws is made in one wave.

The tile is fixed in such a way that the edges of the elements do not reach the axis of the valley about five centimeters. Pre-made markup, and then each element is cut using a diamond circle. After trimming, the end faces of the shingles need to be tinted, their color must match the main one. The holes prepared in this way, at the top of the lock, are drilled. Through them the wire is stretched, with the help of which the tile is fastened to the crate. At the final stage set the upper valley. Under it, put a sealing self-adhesive tape.

How to bend a valley

The roof of the roof can be made of a wide strip of galvanized sheet, bent along at the required angle, the value of which depends on the angle of inclination of the roof slopes. In either case, the edges of the chute must also be bent outward. Thanks to this, the water will not become damp under them.

Endova is a significant element of the roof. The tightness of the roof as a whole depends on how correctly it is installed. Therefore, all installation work must be carried out with strict observance of all put technologies.
