The correct way to install a gutter system


In this article we are gonna to present you the correct way to install a gutter system. One of the key steps in arranging a home drainage system is the gutter one. Without taking into consideration to install one, it is impossible to protect the facade of our buildings from rain and also water that flows when the snow melts.

The proper installation of gutters

The main points when designing a gutter system is the question about how to equip the gutter system, something that must be decided at the construction design stage. Remember that when performing our calculations, we should always be guided by the requirements of the current SNiPa 2.04.01-85. This approach will allow, taking into account all the nuances, to correctly choose the best design option.

The main points to be followed when designing a gutter system:

  • Having made a copy of the roof design, draw a drawing of the location of the drainage elements.
  • Calculate the total area of ​​the roof and all its slopes separately, taking into account the adjacent vertical walls.
  • Based on the indication of the intensity of rainfall in the area, determine the performance of the system.
  • According to the values ​​obtained, determine the diameter of the assembled bottom pipes, the number and cross section of the drainage hoppers, as well as their frequency along the wall of the building.

The result should be a system that is capable of collecting and draining the maximum amount of liquid.

During the design stage, it is important to determine the position of the lifts, so that they do not violate the external composition. They are most often placed in the corners of our buildings, but it is quite acceptable to equip them in a place created by the window bay.
If the drain pipe from the gutters is to be emptied into the blind area, the elevators should be removed as much as possible from the entrances to the basements, the ventilation outlets in the basement and the sidewalks near the house.

The components of the roof gutter system

The gutter system consists of two groups of parts, the horizontal and the vertical drainage parts. Together they are almost about twelve types of building blocks, each of which performs the task assigned to it.
The structural elements of the sewerage system are:

  • drain pipes – key operating system components designed to carry masses of water from the roof
  • gutters – narrow water collection and redirection channels
  • pipes – the conical sockets at the top of the pipe are designed to collect, delay and drain water flowing down the gutters
  • knee – structures in the form of small bent pipe sections are installed to change the direction of water flow
  • brackets – fasteners for fixing the gutter to the roof
  • seals – additional elements provide resistance to fastening to the joints
  • clamps – fasteners for fixing the structure to the facade of the building

When building a gutter system on large sloping roofs, additional guide rails are installed. Their main purpose of them is to reduce the flow rate of the water along the surface of the roof. The shape of the gutters and brackets can be any. There are products in the market that can be round and semicircular. Also, U-shaped and trapezoidal sections.

Gutters differ in the way they attach to the arm. The easiest way is to install the type of systems that require fixing with a simple button. The rotating latches included in the package provide you with the opportunity to disassemble part of the gutter with little effort, in case that it is necessary to replace or carry out the repair work.

Drainage hoppers are universal, so they can be installed in any place in the sewer system. Gutters used to cover the gutters are available in two versions: left and right.
The connection of the drainage pipes and water outlets from the base of the building is something that can not be done without the use of elbows. Their number is determined by the fact that for each drain pipe, installation requires three elbows: one at the bottom and two at the top.

The use of clamps is to fasten the gutter structure into the facade of the building. For metal water pipes, we select connectors with screw elements and a long hairpin. For PVC one’s, we select plastic clips with two support points.

Hardware type options

The price of the sewer system can depend on many factors, one of which is the construction material. The market nowdays offers us many options about the materials that you can choose when arranging a sewer system. The choice largely depends on the appearance of the building and the aesthetic ideas of its owner. Products widely used in gutter systems are polymers and metal.

Each species has its advantages and disadvantages:


It is lightweight, durable and at the same time quite easy to process material. At a low price, it shows excellent functional parameters. The installation of PVC gutters does not cause particular difficulties.

Galvanized steel

Stronger and more durable material than polymer. To give the product a more visible appearance, the manufacturers coat the steel with a polymer coating


Lightweight and easy to use material, whose lifespan reaches over half a century.


The copper systems are beautiful and durable, but at the same time it is quite an expensive metal. It is vulnerable to the harmful effects of electrolyte vapors. To minimize the risk, all components of the system must be made of one material.

General instructions

The use of polyvinyl chloride is to make the ingredients much lighter than the metal. This makes it possible to install brackets with a smaller cross section, without losing the mechanical strength of the construction. But when installing PVC structures, linear variations in dimensions must be taken into account.

Compensatory joints allow key components of the system to shorten and lengthen without the risk of deformation. They are also used in the installation of metal gutters, although they have much less thermal expansion. EPDM rubber acts as a material for making seals. It is a modern analog rubber. To further protect the rubber and simplify the installation process, the sealants are additionally treated with silicone grease.

Gutters produce sections of one to four meters. They come in rectangular and round sections. In their performance, this does not appear. The choice is limited only by the design solution of the sewer system and the design solution of the facade of the house. When buying gutter pipes made of polymeric materials, keep in mind that they have the same diameter along the entire length. Therefore, to connect them, you will need to use special connectors, which entails additional costs.

Roofs can be thermally insulated either:

  • entirely externally or,
  • entirely internally

The first case consists mainly of construction while the second repair. In both cases there is a need for ventilation to prevent condensation.

Types of roofing

In the thermal insulation of roofs we distinguish the wooden and the sloping concrete roofs. Depending on the type of tile used (nailed / laced or muddy), the final choice of the configuration of the final receiving surface of the tiles is made. Roofs under which people usually live or work are considered warm roofs. In this case the thermal insulation is done either externally or internally on the sloping surface of the roof. In the case where there is a horizontal slab between the roof space and the living space, with limited traffic, then the roof is characterized as cold. In this case the thermal insulation is done on the horizontal plate. Thermal insulation materials intended for the thermal insulation of sloping roofs must have properties suitable for the application, such as:

  • Low coefficient of thermal conductivity, to use the smallest possible thickness of material.
  • Resistance to water vapor permeability, to reduce the risk of water vapor condensation in the contact area of ​​the concrete element and insulating material, when the latter is placed internally.
  • Ease of handling in terms of weight, dimensions, mechanical strength and the way the material is fastened.
  • Ease of cutting, shaping and adapting to the shapes of the roof elements.
  • Possibility of good assembly of the pieces of insulating material, in order to avoid the thermal bridges and the lines of condensation of water vapor in its joints.

Roofs covered with muddy tiles

For the thermal insulation of roofs made of reinforced concrete slabs, it is recommended to install thermal insulation on the upper side.

Gikas Roofing engineer who will study the thermal insulation of a roof covered with muddy (“swimming“) tiles, must take into account three factors that determine the correct construction:

  • First, it will determine if the slope of the roof and the type of tiles he has chosen can ensure the desired degree of water tightness. Otherwise, choose the location and type of sealing layer to be used, i.e coating material or sealing sheets.
  • Second, it will protect the roof from the dangers of slipping and wind suction of its coatings.
  • Third, it will address the problem of thermal stress of the tile mud on a high-performance insulating material.

Indicatively, the series of works for the thermal insulation of a roof that does not need additional sealing is described:

  • Smoothing of the reinforced concrete slab.
  • Manufacture of boxing beams of insulating material.
  • Installation and welding of insulation on the concrete slab with suitable asphalt adhesives special for extruded polystyrene slabs or polyurethane adhesive insulation.
  • Fastening a light mesh on the insulation with hairpins and anchoring it to its perimeter boxing beams.
  • Mud and laying of tiles.
  • Gutter construction.

Classic way for nailed tiles

The thermal insulation of the roof, done with a system efficient and suitable for traditional types of roofing materials, allows a significant reduction of energy losses of the building. If applied to the structure, the thermal insulation also performs an important protective function in relation to the structure itself, especially when it is made of wood. In most cases and for sloping roofs (wooden or beech), wooden beams and poles are used in a formation, so that there is ventilation with an intermediate empty part. The distance between the bars is usually 315 mm, for the use of the most common nailed tiles, for the use of the most common nailed tiles.

  • Ready for easy cutting by hand every 315mm.
  • It has a direct and accurate application in the predetermined dimensions between the rafters and the rafters.
  • Significantly reduces application time and grout, while offering greater thermal insulation protection.

Finally, the roof is tiled following the known construction methods.

Unused attics

In buildings where the attic is not used for roofing purpose, thermal insulation can be done by placing an insulating layer on the surface of the top floor. In this case, insulation will be used, which will offer an excellent continuation of the insulating layer, simple to install and unaffected by moisture and water-coagulation-melting alternations.
