Livnevka on the roof: how and where to remove water from the roof

Controlling the amount of water on your roof is essential to preserving its life and making sure your house stays dry. The "livnevka," or guttering, is an essential part of this system since it diverts rainwater from the foundation and roof. Water collecting on your roof can cause leaks, structural damage, and even the growth of mold inside your house. This can be avoided with properly installed gutters.

The first step in effectively removing water from your roof is selecting the appropriate gutters. They are made of a variety of materials, including vinyl, steel, aluminum, and copper, each of which has a unique degree of aesthetic appeal and durability. When managing the amount of water that collects on your roof during rainfall, the size and shape of the gutters are also very important.

Another important consideration to make sure your gutter system functions well is location. Installing gutters with a slight slope in the direction of the downspouts—vertical pipes that carry water from the roof to the ground or a drainage system—is recommended. These downspouts must be installed and maintained properly to keep water from collecting near your foundation, which over time can lead to major structural problems.

The secret to keeping your gutter system in excellent condition is routine maintenance. This involves clearing away any debris, such as leaves and twigs, that may clog gutters and downspouts. Overflowing gutters can cause water to back up onto your roof or cascade down the sides of your house, possibly damaging your siding and landscaping.

Finally, to help keep debris out of your gutters while still allowing water to flow freely, think about making an investment in gutter guards or screens. With these guards, you can lessen the amount of times you need to clean your gutters and keep your gutter system functioning properly all year long, especially during periods of intense precipitation.

What is a storm sewer of the roof

A livne sewage system, also known as a storm drain, collects rainwater and melts it off the roof. It then directs and releases it into a sump, sewer manifold, or designated storm channels that run alongside the street. Furthermore, the point at which drains are released into a closed container or the sewer is crucial. This is a regular drainage system, not a roof-mounted storm sewer, if the water is just collected and dumped onto a blind area or street. However, this is if rigid.

In actuality, storm from the roof and drainage system are synonymous terms for the majority of private developers. This makes sense, considering that not all multi-story buildings and commercial buildings have a complete storm sewer system. And this is exotic for private homes.

Why do you need a storm on the roof

The storm sewer simultaneously resolves multiple issues:

  1. Protection against water flow through a cornice overhang. If there is no drain, with a strong braid wind, rain water freely falling from a slope can blow under the cornice.
  2. Wall protection from getting wet. Everything here works on the same principle, but with one exception – if there is no storm sewer from the roof of the building, then the walls will get wet guaranteed, since in this case even a small breeze is enough.
  3. Reducing the likelihood of washing the foundation. The water falling from the roof will wash out the soil from under the blind area, which over time can lead to a weakening of the foundation.
  4. Reducing the number of icicles on cornices in winter. Although in the winter on the eastern groove they hang picturesque ice ranges, if it weren’t, there would be much more icicles.
  5. Prevents the drain of water from the roof on passers -by, Parked cars, near buildings. This is especially important for houses whose height is more than 10 m. For them a storm sewer on the roof is a mandatory requirement.
  6. Does not allow dirt from the roof to get on plants and a lawn near the house. It is not only unaesthetic, but also promises to plants of the disease.

Due to the walls’ absorption of moisture, the house will initially appear messy in the absence of stormwood on the roof. Then, costly repairs will be required, such as replacing the cladding that has been dumped, rebuilding the cornation overhang, and fortifying the foundation.

Types of storm roof

There are two varieties of live sewage on roofs:

  • open (hinged, external);
  • internal.

Even though both kinds of storms are necessary to remove water, they differ greatly in terms of their features and applications.

Open storm system

This is a well-known drainage system that is suspended from the pitched roof’s eaves. Given that rocky roofs are far more common than flat roofs, the majority of stormy belong to this type.

Advantages and disadvantages

Lift the Living Switch Roof:

  • simple in installation, repair and cleaning;
  • inexpensive;
  • light;
  • effective;
  • can become an organic part of the design of the house;
  • elementary in the calculation and design for houses with simple roofs;
  • mounted quickly;
  • reliable.

This generally indicates that the widespread use of open drainage systems is not surprising given their benefits. Even low-lying buildings’ flat roofs are subject to open rainflows. In this instance, the overflow funnels—installation of which necessitates the creation of a through hole in the parapet—are responsible for collecting and draining water from the gutter. Furthermore, this type of storm sewer is essentially the only choice for pitched roofs.

Nevertheless, you can’t use open gutters in every building. A hinged storm sewer is not appropriate for certain buildings for a variety of reasons:

  1. Limited drainage throughput. With an increase in the roof area, the throughput of the outer drainage system grows significantly more slowly than the volume of rain dropping on the roof.
  2. Cannot be installed on high buildings. According to SP 118.13330.2012 An external organized drain is allowed only for buildings of five floors or less.
  3. Relatively high risk of clogging. Once a storm sewer on the roof is open, garbage can easily get into it, for example, leaves and branches. And in arid time in the drain they like to twist the nest of birds.
  4. Increased risk of osa formation. Even a absolutely correctly made drain in winter can score the frozen comments of snow. Because of this, meltwater will shimmer through the edges of the gutter and turn into icicles.
  5. The risk of breaking the wind or when snow gathering in winter. If the installation of a storm sewer on the roof is made correctly, this risk is almost zero. But an abnormally strong wind can still break even a well -fixed drain.

That is to say, external storm sewers are typically not suitable for a drainage system from the roofs of large shopping centers, multi-story residential buildings, and production facilities. Furthermore, installing an open drainage system is less justified the larger the roof area. Furthermore, if the building is located on a busy street, this kind of storm is not the best choice.

The device of the rainfall from the roof during external installation

There are four primary components of the roof’s open storm sewer:

  • drainage gutter, in which water flows from slopes;
  • Running funnels, through which water from the gutter enters the outlet pipe;
  • drain pipe, which ends either at 250-300 mm above the ground or connected to the sewer system;
  • dead end plugs, which close the free edges of the gutter.

Various bouncers and knees for adorning the gutter turns and pipe bypasses are crucial components of the roof’s storm sewer system. You can only gather a very basic drainage system without them.

The remaining components are optional, such as gratings to shield the gutters from debris and install a downpour from the roof. However, they improve its dependability and efficacy.

Inner storm sewer on the roof

The inner drain is a storm that is laid inside the structure rather than suspended at the cornices. These are always storm sewers, not outdoor drains, because there are no internal systems to dump the collected water onto the sidewalk.

Advantages and disadvantages

The roof’s internal storm sewers are nearly identical to the external ones. Such a tempest

  1. Put on buildings of any height. If the structure has six floors or more, then this is generally the only possible option.
  2. It does not freeze in winter. The pipes are laid inside the building, so there can be no ice traffic jams in them.
  3. There can be any bandwidth. Distribution funnels can be placed at least every meter, and a divery pipe can be generally any diameter, including made to order.
  4. Protected from extreme weather with the walls of the building. Any wind does not care.
  5. Greatly reduces the likelihood of osa On the cornice.

Internal storm sewers are required for flat roofs, particularly those with a big area. But it is very seldom made in homes with pitched roofs. And why:

  1. High price. The need for full design, expensive materials and extremely complex installation make an internal storm on the roof is multiple more expensive than the outer.
  2. The complexity of installation. Stretch through the entire building a network of pipes, cut the funnels into the roof, connect the system with sewage – this is not a groove on the cornice.
  3. The consequences of poor installation or wear are heavier than the consequences of. Lakes of inner stormy – these are leaks inside the building with all the ensuing consequences.
  4. The complexity of maintenance and repair. If the internal storm sewer of the roof is clogged, then specialized equipment will need to be cleaned.

Furthermore, the internal drain cannot be installed inside a home’s wall, per the standards. Furthermore, there is just nowhere to do it on pitched roofs outside of the walls.

The benefits of internal drainage are entirely outweighed by these drawbacks. As a result, it is typically made in areas where installing an outer storm is not feasible.

How the internal drainage system works

The four components of an interior sewage system are as follows:

  1. Water collection funnels. They are placed in the deepening of the roof so that they collect water more effectively.
  2. Diting pipes. Channels through which water enters the riser.
  3. Riser. A vertical pipe passing through the entire building and connecting to the sewer or collector.
  4. Lukes-revisions. These are parts of the pipe with hatches that are needed to serve the system and evaluate its condition.

As the water won’t gather at the funnels without it, another section of the internal storm sewer can be thought of as a rally on the roof.

Location Method
Flat Roofs Use gutters and downspouts installed along the edges to collect and direct water away.
Pitched Roofs Install gutters and downspouts at the eaves to channel water into a drainage system or rainwater harvesting setup.

Maintaining the structural integrity of your roof and avoiding water damage require proper drainage of rainwater from the roof. Installing gutters and downspouts, or "livnevka" as they are known in Russian, is an essential part of this procedure. Rainwater that falls off the roof is collected by these systems and directed away from the foundation of the building.

Take into account the local climate and your roof’s design when arranging the installation of gutters and downspouts. Water should be efficiently captured by the design, with no overflow or obstruction problems. While downspouts direct water either horizontally away from the building or vertically to the ground, gutters are normally placed along the roof’s edges.

Maintaining your gutters and downspouts properly requires routine maintenance. To avoid clogging, remove debris like leaves and twigs on a regular basis, especially in the fall when there are a lot of leaves. Examine the entire system for any damage or leaks that might impair its functionality.

Consider taking extra precautions, like installing gutter guards or screens, to prevent debris buildup in areas that receive a lot of rain or snow. These upgrades can lessen the frequency of cleaning requirements and help maintain appropriate water flow. In addition to protecting your roof, well-maintained gutters and downspouts also extend the life of your house.

Controlling "livnevka," or rainwater runoff from your roof, is essential to preserving the longevity and structural integrity of your house. This article explains how to divert water away from your roof and foundation by using sensible techniques and placing gutters and downspouts in strategic locations. By installing these drainage systems correctly, you can guard against structural problems, water damage, and mold growth, keeping your roof strong and your house dry during the rainy seasons."
