we install on the roof of the house - how to do it right Before you start designing your gutter systems for a private, wooden house, as well as the calculation of the required quantity, you need to familiarize yourself with the key components

To begin with, you, at least, you should know what area your roof will be.

From this data, the capacity of the roof drainage system, the size of the gutter and the diameter of the downpipes are calculated.

Then you need to start choosing the material from which your future gutter will be. Today the market offers a huge selection of gutters for every taste and wallet. Of course, when choosing, first of all, you need to proceed from the strength of the material, as well as how the gutter will look on the facade of your house.

Main components of the gutter

  1. Brackets

Brackets must be supplied. They serve to attach the drain itself to the roof.

There are now various sizes, materials and even shapes. As a rule, they always match the color of the drainage system.

we install on the roof of the house - how to do it right According to the shape, the brackets are attached in various ways, which can be divided into three groups:

  1. in the first case, the bracket is attached to the frontal roof board - this is the simplest and most often used method. Such a drain can be attached to an already finished roof. Of the advantages, it can be noted that they can withstand heavy loads, thanks to powerful vertical ribs;
  2. in the second case, the drain is mounted strictly before laying the roofing material on the roof.

    Here the gutter is already attached to the rafter leg. This method is best suited for large roofs. Advice - in order for your gutter to hold securely, when choosing this method, keep in mind that the step between the rafters should be up to 60 cm;

  3. in the third case, use combined brackets or long hooks that are attached to the lowest edge of the flooring ...

    This method is suitable for you if your distance between the rafters is more than 60 cm. Advice - follow the rules and order when installing hooks. This will ensure the durability and reliability of your structure

  1. Gutters we install on the roof of the house - how to do it right

Chutes are divided according to the types of sections:

  • rectangular,
  • round,
  • semicircular,
  • oval,
  • combined section.

It is important to remember that hooks and gutters must have the same shape and come from the same system.

The most versatile gutter is a symmetrical gutter, because it will be easy to match all other components to it.

Also, the gutters are divided according to their method of connection with the bracket.

The most common is snapping, with simple rotary latches. This structure is very easy to dismantle in the future.

It is also important to remember that gutters can become icy in winter, so at the design stage it is necessary to decide how you will insulate them. we install on the roof of the house - how to do it right

  1. Seals

Used for tight connections .


  1. Funnel for gutters

They serve to collect the flowing water. There are three types - right, left and through. If your gutter is made of metal, then you can install these funnels anywhere, but in this case, you will need to cut a hole for them

  1. Elbows

These are curved pipes that are used to connect funnels and downpipes, and of course to divert water from the foundation.

Keep in mind that for each pipe you will need, on average, three bends: one at the bottom and two at the top.

  1. Downpipes

When choosing between metal pipes and PVC pipes, it is important to remember that in the case of PVC pipes, they have the same diameter, this can lead to additional costs, because additional couplings are needed to connect.

Also, pipes can have different sections - round and rectangular, and an internal drain can also be arranged. Here, the choice depends only on your design, and which pipes will be best combined with your design.

  1. Clamps

Using clamps, pipes are attached to the facade of your house, forming a drainage system.

They come in different shapes, you also need to choose based on the design of the facade of your house.

What material to choose a drainage system from?

we install on the roof of the house - how to do it right When you understand what parts you need, you need to decide what material your drainage system will be. Each material has its pros and cons, and the final price of your drainage system also depends on the choice of material.

Next, we will analyze the most common:

  1. Plastic . The main advantage of this material is its price.

    Such material always has a low price combined with strength, ease of processing and lightness. It is also easy to give such a gutter absolutely any color that the design of your facade requires. The paint will last for a very long time. Also, unlike metal, plastic is not corroded, resistant to ultraviolet radiation and mechanical damage. The advantages include ease and ease of installation.

    Also, the drained water will drain less noisily than on a metal gutter.

Of the shortcomings of this material, it can be noted that plastic weirs may not withstand the snow from the roof.Also, the calculations will have to be approached more thoroughly.

  1. Сwe install on the roof of the house - how to do it right hoist . Steel pipes are stronger and more durable than plastic, but less beautiful.

    Most often you can find such pipes, made in white or brown. Among the shortcomings, it can be noted that this material is more expensive than plastic, plus it is necessary to transport and install such a structure more accurately.

  2. Copper . One of the most expensive drainpipe materials, but durable. Its service life can be calculated for more than one century.

    It is important to follow the rule - if you use copper for your pipes, then you need to perform all other components from the same material. Avoid the formation of electrolyte vapors, as this can destroy all of your pipes.

  3. Aluminum . Of the advantages - a very light, at the same time durable material, which, like plastic, can be painted in any color. Service life over 50 years.

  4. Zinc-Titanium . This option is suitable for locations with extreme weather conditions. But zinc is very finicky, and if you chose it, then you need to remember about observing some points. Firstly, this metal should in no case come into contact with PVC, roofing felt and vapor barrier membranes. You can also work with it only at an air temperature above + 10 ° C.

    Also, one of the disadvantages is a very expensive material, so if you decide to use this particular material, then it is better to entrust it to professionals

Calculation of materials for the drainage system

After you have selected the material, you need to start calculating the amount of materials you need.

You can do this yourself.

  1. we install on the roof of the house - how to do it right The first step is to calculate the exact number of gutters. To do this, count the total length of the slopes on your roof from which you need to collect water, and get the length required for the gutters.
  2. Then, from the condition that an average funnel must be installed for every 10 m, you can count the required number of funnels.

  3. By the number of funnels, you calculate the required number of pipes. This is the distance from the roof to the ground.
  4. Calculate the number of bends depending on your facade. It's okay if you're wrong, you can always buy them.
  5. Finally, calculate the required number of brackets and clamps.

    There is one bracket for each meter of gutter. Each separate section of the pipe must be fixed with one clamp, at least.

What do you need to install?

we install on the roof of the house - how to do it right When all calculations produced, all parts purchased, you can proceed directly to the installation.

To do this, you need to prepare the following tools:

  • marking cord;
  • hammer and mallet;
  • tape measure from 3 meters;
  • hacksaw for metal;
  • scissors for metal
  • universal screwdriver;
  • hookbend;
  • pipe pliers ..


  • drill with battery

Stages of installing the gutter with your own hands

  1. determine the location of the brackets;
  2. make marks on the brackets to determine the slope of the gutter;
  3. bend the brackets according to the ready-made marks. You will need a hook here. After that, install the extreme brackets and pull the cord between them to install the remaining holders;
  4. then, the gutter itself of the required length is assembled directly. A hole is sawn about 150 mm from the edge of the groove (in the form of V, diameter - 100 mm we install on the roof of the house - how to do it right )
  5. then it is necessary install an outlet funnel for the downpipe.

    Then you need to bend the petals of the funnel.

  6. then install the gutter, for this it is necessary to lay all the parts of the gutter and attach the already prepared brackets. Then attach the strip to the crate. It is important that the edge of the grate falls into the gutter of the gutter itself. Above the eaves, the edge of the roofing waterproofing is wound up so that the resulting condensation does not enter the drainage system;
  7. we connect the gutters, overlapping 2 - 3 cm on top of each other.

    We fill the gaps with rubber seals for tightness;

  8. install a protective film to protect the drain from debris. To do this, we mount it in the hole of the funnel in the gutter;
  9. we mount the overflow limiters, most often they are located under fragments of roofs where there are abutments;
  10. we fasten the connecting pipes. To do this, we connect two elbows of the drainage system to each other. You will need to calculate the required length individually;
  11. the last stage is the fastening of the drain pipes themselves. To do this, clamps are first attached to the wall at the pipe joints.

Also, if you are confident in your abilities, you can build a drain in your private house yourself. It will, of course, be much cheaper, but that does not mean that it will be of better quality.

If you nevertheless decide to act on your own, then here are some tips for you:

  • Weirs can be made from galvanized profiles that are used in drywall. To do this, you need to fold the profile and cut off the excess.
  • For installation, attach a galvanized tape, about 2 mm thick, with holes.

    It can be fixed with rivets, screws or bolts.

  • Bend the fasteners to reach the desired incline level.
