In the winter time of the year, ice may form on the roof of the building, which leads to the fact that the passages are clogged so that melt water drains down through the drains. As a result of this, icicles and growths form on the eaves of buildings, which at any moment can break down and cause not small harm.
In order to prevent this from happening, various systems are used that ensure the heating of the roof and gutters. The peculiarity for all systems is that they are all quite simple, and easy to operate the structure, with accessories included in the kit to prevent the appearance of ice and icicles on the roof of the building. In order to prevent this from happening, a heating cable is used, which is laid directly along the edge of the roof and in the drainpipes and gutters themselves, which provides free passage with melt water. The entire process of operation of these systems occurs in automatic mode using thermostats, which enable and off the heating, depending on which temperature on the street. True, there are more complex options that work depending not only on the outer temperature, but also on precipitation, usually from snow.
There are also various types of heating cable used for roofs and drains. They are also two types: self -regulatory and resistant. Depending on the type of cable, the price of the heating of the roof changes.
In systems with resistive cables, with which roofs and gutters are heated, a metallic core is a heat withdrawal. During the supply of electric current, residential heat is released due to internal resistance. The main advantage of the cable heating of the roof is its cost. After all, this method is enough.
In systems with a self -regulating cable, the main source for heat is the matrix, which is located between two cores conducting current. The choice of heating system depends on the type of roof and your financial capabilities
