Endova on a flat roof: what is it and how to do it correctly

Many modern buildings have flat roofs, which provide a sleek and simple appearance. But these roofs need to be carefully maintained and waterproofed, especially when it comes to the important detail of the roof edge. The endova, sometimes referred to as the perimeter or edge flashing, is a crucial element in this context.

By acting as a barrier, the endova shields a flat roof’s edges from water leakage into the building beneath. It is made up of a metal flashing that covers the seam where the roof deck meets the outer edge and runs the length of the roof. Because water tends to collect at the edges of flat roofs more frequently, this flashing is essential to preventing leaks and water damage.

The efficacy of the roof’s waterproofing system depends on the endova being installed correctly. It entails making sure the flashing connects seamlessly with the roofing material and securing it firmly to the roof deck. This procedure not only increases the roof’s longevity but also gives it a polished, clean appearance, which adds to its overall aesthetic appeal.

Paying close attention to details is crucial when installing the endova. For the flashing to fit precisely along the roof edge, careful measurements and cutting are required. It needs to be firmly secured with the right fasteners that work with the flashing material and the roof deck. Furthermore, any gaps or joints can be filled with caulking or sealing compounds to improve the watertight seal even more.

In summary, even though the endova might seem like a little detail, its importance in preventing water intrusion into a flat roof cannot be emphasized. A roof’s lifespan can be extended and the likelihood of future expensive repairs reduced with proper installation and maintenance, which guarantee the roof’s resilience to the elements.

Endova on a flat roof – what is it and where does it come from

Despite the name, a flat roof is rarely actually flat in practice. Rain and melted water off the roof require at least a minimal slope. If not, even the most dependable coating won’t be able to survive more than three to four years.

In its most basic form, a flat roof is very similar to a single-sloping roof; the only difference is that the slope is much smaller, with a maximum of 14 °; in practice, however, it is typically 1.5–2 ° for operated roofs and up to 5 ° for unpromised roofs. These straightforward flat roofs are used on modern, small private homes, outbuildings, garages, residential complexes, and other structures of a similar nature. Naturally, a flat roof in this situation does not have any yends.

Large area flat roofs are home to infronts. These are typically the roofs of public, commercial, administrative, or industrial structures. These result from the fact that such roofs’ surfaces cannot have water drawn from them due to their uniform inclination. As a result, the values found on flat roofs are nearly invariably internal drainage system satellites.

In order to drain water from large roofs, a ramp is constructed. This unique relief enables the water to be directed to the appropriate location, such as the parapet funnel or water intake, avoiding vital equipment and staying away from adjoining junctions, including parapets. The lowlands, where two inclined surfaces with opposing slopes converge, and the peaks, also known as skates, make up such a detector. These are the lowlands. This picture clearly illustrates the yndov of a flat roof:

There are more on a flat roof with a more pronounced relief. And this has a detrimental effect on the roof’s dependability.

What are bad yendovs on flat roofs

A stagnant zone is shown on the diagram of the plane roof in the previous section. Since all of the roof’s water is collected in the lights, this element’s name best captures its essence. Additionally, this water can remain in the light clock in the event of intense rain or snowmelt. In comparison to comparable components on a pitched roof, this renders the yendovs on flat roofs even more vulnerable in terms of leaks.

Even with properly constructed apple nodes, water will eventually spoil from stagnation, especially during the winter when roller roof coatings have microcracks on their surface. They show up there when things are being moved, painted, rolled, and just when things are working. During the winter season, water from melting snow seeps into these microcracks. If the moisture does not have time to evaporate during the day, it freezes again at night, causing the microcrack to enlarge and expand slightly.

Microcracks will grow larger and larger with each such cycle, eventually transforming into a true crack. At that point, the water will start actively assisting UV light. The bottom line is water seeping through the roll’s canvas and the yendov flat roof leaking.

How to increase the reliability of a flat roof with a rampant

We’ve already covered why Endov on a flat roof is bad. What should I do with it now? The following actions will considerably lengthen the roof unit in the fan’s service life:

1. The number of yends on a flat roof must be minimized.
2. Where you can’t refuse mosselines, they need to be made as steep as possible to accelerate the drainage of water.
3. The drainage system must be designed so that the drainage of water from the roof even after a strong rain takes less than an hour. For greater efficiency and predictability, it is advisable to use siphon and vacourse gutters.
4. Water intake should always be the lowest section of the roof. Even its slight elevation above the apple flat roof will lead to stagnation of water in the fan.
5. To avoid blocking the flow of water and the formation of stagnant zones in winter, it is advisable to lay the heating cable in the yndovs. He will not only melt snow, but also accelerate the drying of the roofing.

Furthermore, it’s important to steer clear of lowered areas, roofing curtains, and extremely sharp angles where slopes converge when arranging yendov.

Our article "Endova on a flat roof: what is it and how to do it correctly" at "All about the roof" delves into the fundamental practice of endova installation, which is vital for preserving the longevity and integrity of flat roofs. Endova is a protective seal that guards against leaks and structural damage by keeping water from penetrating beneath flat roof edges. This tutorial will take you step-by-step through the process of installing endova correctly, guaranteeing that your roof will last for many years to come.

Endov arrangement rules on a flat roof

Endov is always formed first when the roll coating is being installed.

First, a two-layer application of bitumen primer is used to impregnate the roof. Furthermore, the application of the second layer is contingent upon the first. Subsequently, an amplification is applied to the roof in the m landing when the impregnation stops spreading and adhering. This zero layer of waterproofing will provide extra defense against leaks. The amplifying layer must have a minimum width of 500 mm, or at least one meter, from the piercing line.

Only the entire roll may be utilized as an enhancing element; longitudinal joints in the protective meter zone are not acceptable. Zero layer of waterproofing with transverse overlap can be applied if the flat roof valve is long, but it must be at least 150 mm long. In order to prevent water drainage from the seam, the roll from the higher section of the roof must match the roll from the lower section at the same time.

The lower waterproofing layer can be laid after the amplifying element has been fused. Although the installation in this instance also began at the Yendovs, the first rolls were made along the M landing line. It is imperative that the joints connecting the lower layer’s waterproofing do not align with the amplification element’s edges. In the lowered area, the side overlap between adjacent panels should be at least 100 mm, and the end overlap should be 150 mm.

Similar to an amplifying layer, it’s critical that the water flow isn’t impeded by either the end or side seams. It is advisable to make cuts to the rolls near the end overflows for increased reliability. This will lessen the possibility of water seeping through the coating.

After designing the water intake funnels, the second layer of the hydraulic tank is melted using the same principle, but with a required shift of half the width in relation to the lower layer’s paintings. Put simply, the lower layer’s joint should line up with the center of the upper roll of waterproofing.

The first roll is rolled so that its central axis coincides with the line of the flat roof’s valley at the same time as the same scenario occurs with an enhancing element.

A roll placed in the flat roof’s valve is melted across its surface, regardless of the kind of bitumen-polymer waterproofing and how it is fastened.

To preserve the longevity and integrity of a flat roof, proper endova installation is essential. The endova, also known as edge flashing, acts as a barrier to keep water out of the roof at the perimeter. It stops water from leaking beneath the roofing material, which over time could cause leaks and structural damage.

It’s crucial to use strong materials that can tolerate exposure to the elements and temperature changes when installing endova. PVC and aluminum are common materials because of their durability and resistance to corrosion. In order to guarantee that an endova installed correctly stays in place and is functional during strong winds and storms, it should be firmly fastened to the roof edge.

Ensuring a seamless connection between the endova and the roofing material is a crucial component of proper endova installation. In order to create a watertight barrier, this is usually accomplished through meticulous sealing and overlapping techniques. The efficacy of the endova can be undermined by any cracks or shoddy sealing, which could result in water damage.

To make sure the endova keeps working correctly over time, regular maintenance and inspection are also crucial. Keeping an eye out for wear, corrosion, and loose fastenings can help stop problems before they get worse. Furthermore, water pooling and possible damage can be avoided by maintaining the endova area’s roof surface clean and clear of debris.
