Install the drain system of the roof with our own hands

The drain system installed on the roof is necessary to remove water from it. If the gutters do not install on the roof, then the life of the entire building will decrease. This will happen due to the constant wetting of the walls and foundation. After a while, you will have to not only paint the facade, but also repair the house, but in particular a blind area. We will consider how to correctly install the drain system on the roof.

Plums for the roof: features, characteristics, varieties

When choosing plums for the roof, such factors as the place of installation should be taken into account, the material from which the roof is built, the amount of precipitation in this area and individual structural features. Depending on the material from which the drain is made, they are plastic and steel.

Please note that plastic plums for the roof are not installed in winter, air temperature, optimal for their installation is at least 5 degrees of heat. Steel drainage systems are installed at any time, they are more durable and stable before mechanical damage. The drain system is a certain number of gutters installed on the roofing. To fix the gutter on the roof, special couplings, knees and other connecting elements are used. In order to correctly establish a drain system, it is necessary to study the principle of its functioning. The main rule for obtaining a high -quality drainage system is the choice of the correct cross -section of gutters and plums.

GOLOB - designed to collect rain water that gets into it from the roof slopes. On special funnels, water flows from the house. The size of the gutters and pipes determines the quality of water collection and its withdrawal from the building. To determine the sizes of drainage gutters, it is necessary to determine the slopes separately on the roof.

For example, if the area of \u200b\u200bthe slope is about 45 square meters, then the minimum value of the section of the gutter will be 10 cm. If the area of \u200b\u200bthe ramp is about a hundred square meters, then the cross section will be 15 cm, and the diameter of the pipes along which water flows - 15 cm.

In the ratio with the place of installation of drain pipes, they are internal and external. The external are located on the walls of the building, and the internal are built into the walls of the house.

Depending on the method of connecting certain fragments of the drain, they have seals on an adhesive and rubber basis. The outer version of the drain is suitable for any type of pitched roof. Installation of the internal system of drainage is carried out in case of arrangement of the roof of a flat shape.

The technology for installing the drain system on the roof

In order for the water, flowing down the gutter to the drain, the gutter should be provided with a certain angle of inclination. That is, the beginning of the gutter should be located above, its final site connected to the pipe. For the normal functioning of the drainage system, it is necessary to provide a gutter of an angle of inclination of three millimeters, on each shoulder strap of the drainage system.

Keep in mind that the rate of water on it depends on the increase in the angle of inclination of the gutters. The installation of too large gutters will lead to water flowing from them during the high rain.

To fix the gutters on the roof, hooks or holders are used, which provide an angle of inclination of the waste channel in one direction or another. To fix the hooks on the frontal board of the building, use screws with a galvanized coating. In the ratio with the place of fixation of the plums, they use different fasteners in length.

The holders are originally fixed, located on top and bottom of the drain. Next, you should pull the cord between them, check its evenness and install the rest of the fasteners. The lower hook is located with a roof by 10 cm. Begining the holders, take into account the slope of the drainage system, the front of which is 4-6 mm below than the back. The maximum interval of hooks is 55 cm.

Installation of drains is carried out from the lower part from the drainage funnels. To do this, install the groove into the inside of its latch, which clicks will fix a certain fragment. To ensure sealing gutter and funnels, special glue should be used, in the case of plastic grooves, or applied adhesion, when installing a steel drain system.

When installing the drainage system, in some cases it is necessary to change the size of the gutter. In order to cut the gutter made of plastic use a grinder or a hacksaw, and for steel structures it is recommended to use exclusively scissors for metal. If you cut steel gutter using a grinder, then there is a risk of damage to the anti -corrosion coating, as a result of a large heating of the metal. After a while, such a gutter will begin to be covered with rust.

Please note that if the length of the slope is more than ten meters, then it is necessary to connect the gutter to several pipes of the drainage system. The middle between the pipes is the highest accurate installation of the gutter. Thus, water will be evenly distributed over the surface.

Installation of the drain system - installation of drainage pipes

Before installing the drain, water intake funnes should be equipped. They connect pipes and gutters on the drainage system. To fix the funnels, special elements in the form of brackets are used. They are fixed on a roofing board or slope.

Installation of drain pipes is carried out on the corner areas of the building or near them. These pipes have a round or square section. The choice of one or another form of the pipe depends on both the features of the facade and the amount of precipitation that falls out in this climatic region. Keep in mind that a square -shaped pipe has large bandwidths, if the length of the house is more than 150 m, then it is recommended to install square pipes of a square shape on it.

Keep in mind that the shape of the plums and drains should be the same. The interval between the wall and the drain is from 25 to 60 cm. For fixing on the surface of the building of the drain pipe, special elements are used, such as clamps and holders. The clamp should have the same shape as the pipe itself. In order to prevent the drainage system with corrosion, galvanized steel is used to make clamps and holders.

After installing the funnels, the trumpet is mounted. At the same time, the upper part of the knee should freely enter the lower part of the pipe. In the lower part of the pipe, the knee is also installed, in compliance with the angle of inclination of 55-70 degrees. To bend the drains, special knees are used. Keep in mind that installing pipes on Earth is unacceptable, since they are easily rotten. The interval between the pipes and the soil is at least 35 cm.

Installation of the roof drain system: external drainage system

Among the main components of the external drainage system of the roof, we note:

• gutter installed under a certain bias;
• funnels taking water from the gutter;
• Pipes on which water is discharged from the building.

Keep in mind that the installation of the funnels is about 30 cm. At the same time, a groove of not more than 8 m is allowed per funnel.

The drain groove is divided into such types:

• Badge -type groove - installed according to the cornice of the roof - one of the most popular gutters;
• Paopeant type groove - is installed between the walls, the use of this design is very unpopular, due to its impracticality;
• The groove of the groove type takes the water to the parapet.

In relation to the shape of the gutters, they are:

• square;
• semicircular;
• rectangular.

In order to equip the standard drainage system, standard gutter of semicircular shapes are used. If necessary, in protecting the drain from dirt and other garbage, a gutters with a relief coating are installed on its surface.

If an increased level of precipitation is observed in the region, it is recommended to set a gutter with a square section.

It is preferable to equip the flow of water from the roof on the south side of the house. Keep in mind that pipes and gutter should coincide with each other in the cross section. For fixing pipes, clamps and special pins made of stainless steel are used.

Depending on the material from which the drain system is made, they distinguish:

• german system made of galvanized tin;
• aluminum;
• copper;
• plastic;
• Titan-toy coating.

The choice of one or another option depends on the individual characteristics of the structure and material state of its owners.

Recommendations for the installation of the drain system for the roof

When installing drain pipes for the roof, you should pay attention to the following nuances:

• Installation of the pipe in relation to the wall of the house is carried out at a minimum distance, a maximum of 50 mm, otherwise, moisture will fall on the wall, constantly moisturizing it;
• Distributions are installed with a mandatory slope, which is equipped in the funnel side, thus, it is possible to prevent excessive accumulation of fluid;
• To seal all the joints and places of installation of the system, cold welding or seals made of rubber is used.

We offer to consider the positive and negative sides of each compaction method:

1. Rubber seals are resistant to mechanical influences, and prevent the flow of the drainage system. However, rubber is instructed in front of high and low temperature, they stretch out of the heat and bursts from frost.

2. The drainage elements connected by glue are very well sealed. However, their disassembly becomes impossible.

3. Using the use of cold welding, it is possible to provide the most reliable way of sealing. With mechanical exposure to the drainage system, it cracks.

The choice of one or another fastening option depends on the material from which the system is built on the place of laying it.

Features of the installation of the drain from the roof

Work on the installation of the drainage system begins with the implementation of design calculations. Initially, how many materials are required in the process of work. First you need to determine the length of the gutter, to calculate it, find out the perimeter of the building.

Next, the location of each funnel is determined, it is advisable to designate them with a chalk or red tape. After the acquisition of all materials, first of all, hooks holding the gutter are fixed on the roof.

When using plastic pipes, hooks are installed at a distance of half a meter from each other. In the process of using steel grooves, the interval is reduced to 35 cm. Next, the funnels should be fixed, after which the gutters are laid into the inside of the holders.

At the next stage of work, the connectors are installed for the drainage system. At the same time, they are installed between the joints of one and the second gutter. Next, pipes and gutter are installed. Keep in mind that when performing the docking of two gutters, it is necessary to take care of the presence of a temperature clearance that prevents their deformation due to their expansion or reduction.

Installation of water drain from the roof is carried out taking into account certain requirements and norms. To fix the funnels, special brackets are used. Keep in mind that the system should be located under a certain bias, otherwise, water will accumulate in gutters.

Pulling the rope along the gutter, you can track the location of the brackets for fixing the funnels. After installing the holders, the gutter is mounted directly. If there are protruding areas on the facade, special corner fragments should be installed. To close the ends of the gutter, special plugs are used.

Next, drain pipes are installed, which are removed from the wall to the minimum distance. You can check the system’s performance by supplying water through the hose to the roof. If water flows through the system and does not remain in gutters, then the system works properly.
