How to install a drainage system with your own hands

The roof of the building is designed to protect it from precipitation. But she herself needs protection. Moisture can accumulate on it in excess, drain from it onto the walls and foundation, gradually destroying them. As they say, water wears away a stone. To prevent this from happening, do-it-yourself installation of the drainage system.

In order to competently perform a design, you need to know what it is and what types it is. In a word, you need to have a certain amount of theoretical knowledge in order to successfully install a drain with your own hands.

What are the gutters

The classification of types of roof gutters is based on two features that determine the nature of the technology when installing the system. The first feature is the manufacturing method. In accordance with this, a distinction is made between a home-made drainage system and an industrial-made one.

Homemade gutter system

The advantage of a do-it-yourself gutter is the ability to make it to your own taste. The nature of the implementation depends on the creative imagination of the owner of the house. A homemade system does not come with significant costs. Moreover, it is allowed to install the drainage system according to the scheme that is most convenient for the owner of suburban real estate and takes into account all the features of this structure. The disadvantages of this design include enhanced control over work efficiency.

Most often they are made of galvanized iron, and such material is capable of rotting. During the installation of a metal gutter for the roof with your own hands, the problem of connecting structural elements arises, since the iron does not bend well. Moreover, the appearance of such systems is not respectable.

Factory gutter system

The factory system meets all standards and parameters. Even when using elements from different manufacturers, there are no problems with joining. Depending on the material used, the system can be made of plastic or metal.

Plastic storm drains

Plastic roof gutters are convenient for DIY installation. They are installed using glue or using rubber bands.

Plastic storm drains have certain advantages:

They are not afraid of ultraviolet light. A plastic drain will regularly serve the entire service life, while retaining its qualities and appearance.
Plastic is not subject to corrosive processes.
If the installation of the drainage system with your own hands is carried out with the help of glue, then such a structure does not need constant maintenance. The installation uses "cold welding", which takes place at the molecular level.
Plastic waste systems are highly durable.
They are lightweight because they have little mass.
Operation is carried out in a wide range of temperature conditions. This allows them to be used in different climatic zones.
Do-it-yourself installation of a drainage system on the roof is not associated with special difficulties.
The finished products have a rich palette of colors.
Plastic structures are equipped with a wide variety of elements. They can be easily mounted on a sloping roof. The complete system itself can have a complex configuration.

Like any product, it is not without its drawbacks:

Plastic does not have sufficient resistance to mechanical stress. Such systems are not installed on high-rise buildings. They are applicable only for low-rise construction.
If roof drainage systems made of plastic fail, they cannot be repaired. The destroyed plastic is not restored.
When installing a structure made of plastic on rubber seals, their constant replacement is required. This is extremely inconvenient, since the entire system has to be disassembled and assembled.
The material has a high coefficient of linear expansion.

Metal storm drains

Roof drains are also made of metal profiles. Copper and zinc are used as materials for such a system. There is an option with a polymer coating. They differ in cost and service life.

The positive aspects of metal drainage are reduced to the following positions:

Sufficient strength of the system.
Such a drain is reliable in operation.
A metal gutter is able to withstand a significant snow load.
Such a drain will not burn if there is a fire.
Wide range of temperature parameters.
Such structures are dimensionally stable.

The disadvantages include the following points:

the drainage system is of high cost;
such a drain has a significant mass;
installation work is of a certain complexity;
insignificant choice of colors;
if the protective layer is damaged, the pipe will rust.

It is difficult to determine which system is better. It all depends on the specific conditions. The choice is also influenced by the region where it will be operated.

We carry out the installation of the drainage system with our own hands

Before starting work, it is recommended to read the installation instructions in detail.

The scheme for installing the drainage system includes several stages:

The main anchorage must be connected to the roof. A large number of fasteners are available to secure the gutter to the roof. It is always necessary to create a slight slope. This will help the water to drain smoothly. The most commonly used gutter bracket. It is placed every 50 cm.
At this stage, a funnel is attached to the drain pipe. It is an intermediate link that connects the gutter and the pipe. In the case of a metal funnel, special fixing devices are used. The plastic funnel is attached with construction glue.
Further, the fastening of the gutter with their own hands is carried out to the roof. It fits on brackets and is fixed with special parts.
For sealing, use special plugs. Such a product has rubber seals around the edges. If you correctly execute the joint, then the water will not flow.
The connection of individual sections of the gutter is carried out. For this, a special technology is used.
The knee connects to the funnel.
Downpipes are attached. The hollow cylinder is connected to the knee with a clamp. If it is necessary to lengthen the east, a pipe of a smaller diameter is inserted.
Which clamp will be used depends on the wall material of the house. Structurally, it looks like a ring on which two bolts are located. The pipe is fixed in one place with a clamp.
The knee closest to the ground is installed. The distance to the ground is 30 cm.

It is recommended to install a drain before the roof is covered with the base material. But you can also do it with a finished roof. But there are certain nuances. If the bottom row of tiles can be removed, then there should be no problems with installation.

It is recommended to use a rafter during installation. They serve as a mounting point for product parts. They can be replaced with a frontal board on which the bracket is fixed.

When the gutter is installed, it is tested for strength.To do this, fill with water. If no flaws are found, this will indicate that such a system will serve the owner for a long time. Its performance will not depend on the amount of precipitation.

How to choose a storm water system

To choose the right gutter structure, you should take into account:

the amount of precipitation in your area;
the area of the largest roof slope, it is on it that the diameter of the gutter is determined.

It is advisable to select and install a gutter at the stage of building a house.

Some types of stormwater systems require lathing. It depends on the design roofs... Therefore, consider the system installation scheme in advance.

The choice of material for stormwater is not affected by the type of roof. Plastic or metal, any is well suited for both a roof with natural tiles and covered with corrugated sheets.

It is easy to see that having certain knowledge and skills, the drainage system can be completely assembled independently, without resorting to the help of outside specialists.
