Device endovy

The complex construction of the roof makes the house more attractive, adds respectability to the appearance of the building. When constructing a hip or hip roof, a structural element appears called endova. It is located at the junction of two slopes and is a place where snow accumulates and drains water. That is why endova device implies tightness and high durability.

Definition and species

Endova - a functional part of the roof, it is a gutter formed at the junction of the slopes. Like any joint, it experiences an increased load, so the reliability of the entire roof depends on the strength and proper construction of the roofing element.

There are two types of endova: the lower, which protects the joint from precipitation and the upper, which, in addition to the protective, also performs a decorative function. The method of installation determines the type of element:

• Open Endova — устраивается на пологих скатах, она является простым вариантом. Стыки скатов имеют зазор, в который укладывается желоб и гидроизоляция.
• Closed Endova - used for the roof, which has steep slopes that fit snugly to each other.
• Interlaced dendowa - with this method, the roofing sheets are intertwined with each other, waterproofing is required.

Training

Schemes of the roofing structure are developed at the design stage, at the same time the type of endova is selected, which depends on the angle of the slopes and the material used for the coating. The lower endova is installed on rafters, therefore it should be marked in the roof plan. Depending on the selected roofing material, the structural element at the junction is made of metal or soft tile.

Note! Galvanized steel is a practical choice, it ensures reliable operation of the valley for a long time.

Mounting endovy

The first step of the endova device is the installation of a continuous batten, it can be made from planks stuffed with a number of boards or cut boards, which are antiseptic to protect against moisture. The width of the batten should be about 20 cm in each direction. A solid surface will increase the strength of the node, which has a high snow load.

Laying waterproofing layer, exclude this component is not worth it, because the roof of the roof should provide full waterproofness. For a sealed base, it is better to use a bitumen-based roll material that has basalt dressing for strength. If the waterproofing consists of several parts, the canvas is overlapped.

The open enda type is used more often than others, for its device it is necessary to make a special gutter. The material for it is a strip of galvanized steel, bent at an angle greater than the valley.

The bottom endova has a bend of the edges, preventing water overflow, it starts up with the lower part to the eaves. In this place the overhang is left in 8 cm for reliable fastening. In the place of joining with the ridge the seal is laid. Fastening is made by self-tapping screws to the crate, the drilling step is 30 cm. Laying takes place from the bottom up, if the chimney consists of separate parts, they are superimposed one on another with an overlap of up to 15 cm. The joints are protected with silicone sealant.

Features of the device

When mounting metal sheets, they are cut, leaving up to 10 cm to the center of the valley. Fastening occurs with self-tapping screws, which are twisted, not approaching the center of the angle closer than 25 cm. The self-tapping screws pass through the metal and the end valley, fastening the structure.

Upper endova is made of roofing material, it is fixed after laying the main coating and closes sections of the laid sheets. It is mounted in the upper points of junction of the metal.

To install the valleys on the roof with a corrugated flooring, you will need a device for continuous sheathing and waterproofing, which is 10 cm wider than the ramp of the valleys by 10 cm. With a small angle between the slopes, the magnitude of the lower valleys must be maintained 50 cm in both directions. The overlap of the parts on each other is at least 20 cm. The bottom endova goes under the ridge by 25 cm. After fixing the professional flooring, a decorative strip is laid.

For soft roof endova settles down in an open way. The end carpet is laid on bitumen mastic and nailed. The overlap of cloths is up to 30 cm and is necessarily glued. Ordinary shingles are mounted 30 cm from the axis of the angle, their edges are fixed with bitumen.

Tips for the right device

1. Closed endova more complex and costly, but it looks more attractive.
2. For effective protection, use several layers of waterproofing.
3. In buildings with a large roof area, the valley can measure up to three meters.
4. The framework for a structural element subjected to high loads must be durable.
5. Do not do work in wet weather.
6. Roofing work requires compliance with safety regulations.

Endova is a complex and crucial element of the roof, its installation should be approached, armed with installation knowledge. The work will help numerous photos and video tutorials.
