What is the yendova on the roof – functions, device and installation method

Yendova is an important part of roofs, especially those with slanted surfaces, but it’s frequently disregarded. This component is vital for shielding the interior and structure of the roof from the elements. Yendovas are decorative accents that are placed at the edges where the walls and roofing materials meet.

Yendovas serve as a functional barrier to prevent water infiltration. Through the process of caulking the roof-to-wall intersection, they stop precipitation, melting snow, and debris from penetrating into the supporting framework. By lowering the possibility of water damage, this protection guarantees longevity and aids in maintaining the integrity of the roof.

Yendovas strengthen the roof’s edges structurally, offering stability and support. They aid in uniformly distributing the weight of the roofing materials and stop them from lifting or moving as a result of wind or other outside influences. This structural support is essential to preserving the roof’s general robustness and security.

Depending on the particular needs of the roof and aesthetic preferences, yendova designs often combine a variety of materials, such as metal, PVC, or even wood. Contemporary yendovas are frequently made to blend in with the building’s architecture and roof style, improving the building’s overall look.

Ensuring effective functionality during yendova installation requires precise positioning and secure fastening. In addition to improving the roof’s functionality, proper installation also improves the building’s aesthetic appeal. For optimum performance and durability, care must be taken during yendova installation, whether it’s a replacement project or a new roof installation.

What is Endova, its functions

Endova is an internal roof component that is positioned beneath the intersection of two slopes. This is actually an internal gutter, the edges of which "go" to the edge of one side of a complex roof’s neighboring slopes.

Endova is also installed in locations where auditory windows are installed or where a vertical wall connects to a roof slope. This inner component is also known as the mocking.

The primary purpose of the yendova is to keep water streams away from the intersection of the ceiling below the roof slopes and the slopes themselves. In the event that the upper portion is installed, it will serve as the final decorative element and shield the joint edges from corrosion.

What is Endov

The kind of roof that will be installed on the roof dictates the yendova’s composition. The Yendovs include the following for heavy-duty roofing materials, such as asbestos-cement slate or ceramic tiles:

  • waterproofing;
  • a support groove or an additional crate from the boards installed along the junction of slopes on both sides;
  • Lower, main groove of yendovs made of a tin plate.

The sheets are called preferential elements and are painted in a color that resembles the main roof’s sheet tint in order to serve decorative purposes.

The Endova includes a simplified version of a support groove in the form of extra labeling planks rather than a solid crate for light tin roofs (metal tiles, corrugated board, and tin).

The lower portion of the yendova is executed as a unique valley carpet for soft roofs.

Of course! This is a succinct summary of the article’s main thesis: The article provides a clear understanding of yendovas’ functions in roofing systems by examining their role, structure, and installation on roofs. It describes the parts of yendovas and typical installation techniques, as well as how they help with water drainage and weather protection. The goal of this guide is to make the idea of yendovas more approachable for homeowners and enthusiasts who want to learn more about roofing components. Does this fulfill your search criteria?

Features of the rafter system

Only roofs where the joints of two or more slopes are planned, on the one hand of the building, require roof installation.

It can be as simple as half-wool roofs with four skeets or as intricate as multi-story buildings. Regarding the construction of these roofs, initially a yendova plan and a joke crate installation are made.


Since the roof is installed at the intersection of two nearby slopes, setting up the installation scheme is not too difficult.

The Endova installation circuit should include the location of her joint with the skate of the underlying roof if one’s height slopes below the skate of the roof of the other portion of the building.

The transition of roof sheets from the upper portion of one slope to the hobby of another roof should be considered in the same scheme.


Installing the gutter boards so that their surface is in the same plane as the surface of the crate on each slope is the primary prerequisite for installing the crate with the apple on the roof.

If you don’t do this, the snow pressure will cause the roof sheets above the apple to distort at their edges. Soft roof types require the crate to be made continuously.

Endova device

The way the landing is arranged under different roofing types varies: on Endov’s lighter and softer roofs, it forms a whole structure; on heavier roofs, its design permits the indentation between adjacent boards.

There are three versions of the element that can be installed for different types of roofs.

  1. Open – when a gap is left between the sheets of the roof of the jokes for installing the upper yendova. This gutter is installed on top of the joint.
  2. Closed – in this case, the sheets of the roof of the joined slopes are adjusted correctly and accurately, and do not need closing.
  3. Intertwined – consists in alternately overlapping the gutter by sheets of the roof of the joined slopes, with a approach to the next direction.

When using rolled materials to create soft roofs, the third option is most frequently utilized.

Advice: The third version requires that a continuous crate be waterproofed before installing a soft roof.

Metal tile or corrugated board

These are light-weight roof types. They are easily deformed, even in light snowfall, as they are composed of thin sheets of processed tin.

They make an improved crate for them because of this, adding extra planks in between the main boards. Endov in this instance is a flat groove made of the same material with upward-facing edges.

The majority of builders choose to install roof sheets with a 3–5 cm space between each edge of a converging slope. This gives you the option to order the Upper Endova, an averted element that takes the shape of a gutter with a rectangular groove served at the bend of the bend.

The squeezed output is situated in the space between the gutter’s edges when laying such a profile, with the gutter’s side sides falling on the slopes.

Fascinating! The upper portion of the yendova cannot be installed even if professionals are installing the roofs and they are able to fit the joint of two slopes qualitatively.

Slate or tiles

These are the worst kinds of roofs for houses. The construction of an ultra-strength and frequent crate is necessary for their device. Simultaneously, the coating’s high bearing capacity means that deformation of its edges over time is unlikely, and the crate’s reinforcement is not necessary.

It is sufficient to install the lower portion of the land on such roofs; the upper part cannot be installed.


This is actually a pliable surface. The crate beneath the yendova for such a coating is constructed of two boards fastened to the connecting slopes, giving the appearance of two different roof types: soft and wavy.

They are kept apart by a space that is the same width as the ledge on a unique gutter that is part of the roof kit.

The preternal element is positioned with its "wings" coming to the edges of the slopes and its groove fitting into the space between the crate’s boards.

Piece bitumen tiles and other types of soft roof

Yendovs install things under these roofs, such as:

  • continuous crate in the form of a wooden gutter;
  • a lining carpet from a polyester canvas or other polymer;
  • yendy carpet from a set of roofs.

Every polymer component is put in place using specialized mastic or glue. The roof racers’ edges are positioned 5-7 centimeters on the yndova, and they are fastened there using rubberized washers and self-tapping screws.

Tin roofs

Coatings consisting of flat sheets of galvanized tin fall under this category. The fans beneath the sheets are designed to form a single unit with the roof’s remaining portion because they are not press-processed.

This is accomplished by making a specific selection along the groove edges, which results in the squeezing out of a triangular ledge whose dimensions match those of a corresponding element on the roof sheets.

Crucial! The yendova is first laid and fixed during roof installation, and the roof itself is then fixed by combining the protrusions on the yendov and on the roofing sheets.

How to install an Endov

Every kind of Jendov roof is installed using the "bottom up" methodology. The highest section of the setting set is transported to the roof’s skate and fixed there.

The construction of a continuous crate is not necessary as a foundation if light forms of hard roofing (corrugated board, metal tiles, or tin sheets) are utilized. In this instance, increasing the number of the basis that fall under the yendov suffices. They are fixed on the two closest rafters and placed between the two neighboring boards of the main crate.

Materials and tools

Because Endova installation is done on the roof, the following minimal set of tools are required:

  • hammer or screwdriver;
  • measuring tool;
  • chalk or marker;
  • Brush for applying glue or mastic.

A roof knife must be included in the list of tools if soft coatings are used.

The device’s list of materials is likewise brief:

  • boards for performing an additional or continuous crate;
  • nails or screws;
  • glue or mastic;
  • Material for waterproofing.

The Klyimers, or residual strips, which serve a purpose, must be added to the list of materials if the lower sheets of the yendovs are fastened to the crate using remote fasteners.

Installation of drainage grooves

The first groove is put in with the drainage system on the outside. In the event that such a design is absent, the first gutter’s edge is bent to stop water from flowing beneath the jail.

The following sheet is installed "overlapping," overlapping the lower sheet’s upper sheet by 15 to 20 cm, and the joint junction is smeared with bitumen mastic or a material of a similar composition.

There are two ways that Endov is fastened to the crate:

  • Klyaimers for the selection;
  • self -tapping screws or nails along the edges of the “wings” of the gutter.

In both situations, the fasteners had to be installed in a way that allowed for overlap with an upper jail or sheet of roof.

The self-tapping screw does not reach the lower part of the upper part because it is fastened to the roof sheets using a self-tapping puck.

Heating yendov

Some experts hold the opinion that metal roofs can still occur even in cases where the roof is well-equipped. When snow builds up between the upper and lower sections, this occurs.

This occurs frequently, to the point where many professionals grudgingly accept jobs involving such uncomfortable materials as metal tiles.

The parties are frequently unable to come to an agreement regarding the refusal of the upper light’s installation. For numerous experts, this component is utterly needless and foolish, adding more harm than good.

Many experts suggest heating it to try to prevent the buildup of ice between the two parts of Endov. Installing a heating cable in the lower section is the only way to accomplish this without having to lift anything up to the roof. Since the method is clearly controversial, each builder must decide for themselves how to use it.

One of the most important components of roofing systems, the yendova, performs several vital tasks. Its main function is to prevent water from seeping through the seam where the wall and roof meet. It averts possible leaks and internal water damage by diverting rainfall away from this weak spot.

Most often made of sturdy materials like PVC or metal, the yendova is made to withstand inclement weather and guarantee long-term dependability. Its efficacy is largely dependent on its form and installation technique. When installed correctly, it creates a seamless junction between the wall and the roof, improving the roofing system’s overall waterproofing capacity.

The yendova installation process requires painstaking attention to detail. Its functioning depends on a tight fit and a stable attachment. Experts frequently use methods like caulking and fastening to create a tight seal and avoid any openings that might jeopardize the material’s ability to shed water.

In summary, the yendova serves as a vital barrier against water intrusion in roofing systems in addition to being a structural element. It is an essential component of any well-built roof because of its design and installation techniques, which highlight how crucial it is to preserving the longevity and integrity of roofs. To maximize its effectiveness and shield buildings from water damage, it is essential to comprehend its functions and make sure that it is installed correctly.
