One of the main functional elements of the external arrangement of the house is the drainage system. It serves to divert water from the roof during heavy rainfall and snowmelt. Some homeowners prefer to install gutters with their own hands. With this approach to repair, you must be very careful, as errors can lead to corrosion of the wall material.
Precipitation causes the greatest damage to the foundation. To prevent the destruction of the foundation of the house, it is necessary to strictly follow the rules for installing gutters.
Consider the basic recommendations for the installation of the structure.

Gutter installation technology
Experts distinguish the following stages of installation of plastic gutters:
- carrying out calculations;
- purchase of building materials;
- system installation.
Gutter systems differ in their throughput. It should be remembered that there is no single standard for pipe sizes, so it is recommended to purchase all design details from one manufacturer. This will avoid misalignment of individual parts.
How to choose a drain
Choosing the right system is one of the main steps in installing roof gutters. In doing so, the following criteria should be taken into account:
- the amount of annual precipitation;
- temperature difference at different times of the year;
- roof slope area.
After choosing the type of system, you can calculate how many building materials will be needed for work. Photos of drains in the manufacturer’s catalog will allow you to determine the appearance of the drain structure.
Types of gutters
The gutters themselves serve to collect precipitation that accumulates on the roof of the house. Their section usually has a semicircular or rectangular shape. The length of the pipes is from 3 to 4 meters.
When installing gutters, special fasteners are used, usually these are hooks or brackets. They are mounted at a distance of 60-90 cm from each other. The whole structure is installed at an angle so as not to interfere with the flow of water.
This type is used to ensure the free movement of water when changing direction. These gutters are attached to the corners of the roof.
Sometimes plastic is used as the material for the corner gutter. It is more flexible than other materials and allows more complex shapes to be created.
Sometimes the gutters are attached to the roof using special adapter connectors. This helps to prevent deformation of the structure when exposed to a difference in ambient temperatures.
Specialized hooks are used to connect the gutter to the roof. Long hooks are used at the construction stage of the building, when the roof is not yet completely built. And the short ones serve to fasten the gutter to the roofing material.
A distance of 60 cm must be maintained between the parts, which allows you to securely fix the product.
A drain pipe also serves to drain water from the roof. It can have a round or rectangular section. There are two types of pipe fastenings to the structure:
- «on stone» if the wall is made of stone, concrete or brick;
- «on a tree» if the pipe is attached to a wooden plane.
Before undertaking an independent installation of a gutter system, you need to carefully read all the instructions for installing gutters and drains. Mistakes during installation can lead to serious consequences.
Stage 1. At this stage, the main fasteners are connected to the roof. There is a huge variety of fasteners that help attach the gutter to a roof or wall.
The main rule when installing the system is to create a slight slope. It is about 5 cm for every 10 m of the product. Such a slope ensures unhindered runoff of water.
The most common fasteners are brackets. The distance between them is about half a meter.
Stage 2. Next, funnels are attached to the drainpipes. They are an intermediate link between the gutter and the pipe. For metal funnels, special fixing devices are used, and for plastic funnels, building glue is used.
Step 3. In the next step, the gutter is attached to the roof. It is laid on brackets, then fixed with the help of parts intended for this.
Stage 4. In order to ensure the tightness of the installation, special plugs are used. Rubber seals are located along the edges of this part. With proper docking of the parts, the possibility of water leakage is excluded.
Stage 5. At this stage, individual sections of the gutter are connected to each other using a special technology.
Stage 6. Next, you need to attach the drain elbow to the funnel. The outlet at the same time looks at the wall, then the pipe will fit snugly against the building. Here you can do the installation of the second knee.
Stage 7. After the knee is connected to the system, downpipes are fastened. The clamp allows you to create a strong connection between the elbow and the hollow cylinder. If it becomes necessary to extend the drain, then you can insert a pipe of a smaller diameter, and thus increase the length of the structure.
Stage 8. The type of clamp is selected depending on the material from which the wall of the house is made. In shape, they resemble a ring with two bolts. They fix the pipe in place.
Stage 9. The final stage is the installation of the knee, which is located near the ground at a height of about 30 cm.
Installation of a gutter on a finished roof
Experts recommend dealing with drainage issues until the roof is covered. But even otherwise, it is possible to make a drainage system. So how do you install a gutter if the roof is already covered? To do this, you need to know a few things.
First, you need to find out if the bottom row of metal tiles is removed. With a positive answer, there should be no problems.
Secondly, manufacturers offer the use of rafters. Long hooks are installed on them, on which the details of the product are attached. An alternative to the rafters is the frontal board, which also serves as the basis for the brackets.
After carrying out all the work, it is necessary to verify the strength of the structure. To do this, a trial run of water is carried out, which washes away construction dust and helps to test the system. If problems are not found, this means that the drainage system will be able to cope with any amount of precipitation and will last for many years.
