Atmospheric precipitation can damage the roof of houses, cable networks, drainage systems, as well as external engineering systems and house communications. In order to protect your home from such unpleasant situations, it is recommended to use roof heating.
Why is it necessary to heat the roof?
The most pressing issue for our climatic conditions is the fight against ice on the roofs of houses. Ice freezes in the pipes and gutters, while the water looks for other ways and therefore leaks form that destroy the facades, as well as break the drainage systems.
In addition, icicles and ice blocks that fall from the roof of houses pose a danger to people's lives.
Advice! The mechanical work that is carried out to clean the roofs leads mainly to significant damage to the roof, followed by costly repairs. It is much more efficient and cheaper to install an anti-icing system on the roof.
Such systems significantly extend the life of the roof structure, as well as save gutters, drainpipes from various kinds of damage, and from destruction - the facade of the house.
Roof heating will eliminate the formation of icicles, ice and ice "caps" on the roof, which significantly extends the life of the roof. Already on the finished roof, a heating system is installed, which will work in automatic mode.
Thanks to automation, the roof is heated when there is a danger of icing and is turned off after the roof is cleared of snow and ice from the downpipes.
For anti-icing systems, heating cables are very reliable, as well as resistant to temperature changes, precipitation, and ultraviolet rays.
Anti-icing systems
These systems operate quite recently and quickly became in demand. Thanks to these systems, ice plugs do not form in the drainpipes, ice does not accumulate in the gutters, and also on the edge of the roof.
The main task of these systems is to ensure the free flow of water from the roof through downpipes and trays. The system can work during snowfall (at temperatures from +3 to -15 degrees).
In our climatic zone, the operation of such systems at low temperatures is not necessary, since at -20 degrees it rarely snows and ice does not form, and at low temperatures it is desirable to have a large electric power.
Your attention! The roof heating system is the most complex system for design and installation.
In order to perform roof heating, in addition to the design of the roofing system, the following factors must be taken into account:
- wind direction and strength;
- orientation relative to the cardinal points;
- solar heating of individual sections of the roof.
The heating system consists of the following parts:
- The heating part, which consists of heating cables and accessories for fastening. It performs the task of converting precipitation in the form of snow into water and removing this precipitation from the roof.
- Distribution and information network, consisting of power and control cables, distribution boxes. It feeds all the elements, and also connects the sensors to the control panel.
- Control system, which consists of humidity, temperature sensors and a special regulator.
The main element of the heating system is the heating cable, which ensures the efficiency and reliability of roof heating.
Heating cables are divided into the following types:
- self-regulating cables;
- constant resistance cables;
- zone cables.
In addition, they come with a metal screen and unshielded.
In the control system, the main element is a special regulator, which can automatically turn off the system after the gutters, trays and pipes are freed from water and snow.
Roof heating is economical
Heating the roof with a heating cable (self-regulating or resistive) protects downpipes and gutters from damage and significantly extends the life of the roof.
In addition, it prevents damage that can be caused by falling icicles, as well as damage to the facade and electrical wiring.
When choosing a heating system for hip roof it is necessary to find the optimal solution from an economic point of view, since not every system is equally suitable for every case.
Modern cable systems do not support combustion, and thanks to the control system they will protect the building from current leakage through the roof. Sometimes cable heating systems are used at gas stations and in children's institutions.
Therefore, such facts characterize the heating system on the positive side, and it is a reliable and safe system for such a design as do-it-yourself hipped roof.
To collect water that flows from the roof, roof gutters are designed to collect the flowing water and divert it into the downpipe.
Therefore, it is necessary to provide in advance the protection of vertical drain pipes from freezing. To do this, often the lower part of the pipe is additionally heated when the downpipe passes inside the building where the rooms are heated.
Advice! Pipes must be protected in places where freezing is possible, and if the pipe goes into the sewer, heating is necessary to the freezing point of the soil.
The cable should be protected from mechanical damage, as well as from snow, which begins to slide down at positive temperatures.
To do this, install a snow catcher in front of the cable track, and if a gutter is installed on the roof, then it performs the function of a snow catcher.
And then the heating cable should be covered with metal sheets. This method is optimal for protecting the cable from damage, and it is also practically invisible and does not affect the design of the building, and you can easily clean the roof of debris and leaves.
