Heated Roof and Gutters: Installation Technology

Heated roof and gutters: installation technology

Winter is not only beautiful landscapes and the game of snowballs but also additional difficulties. Most of them, in one way or another, are related to home heating. The effective insulation of the house will save a lot of money on heating and will make living much more comfortable. But this is not the only thing worth taking care of.

In winter, you will very often notice that huge icicles hanging from the roofs of many buildings. This is a fairly common phenomenon that conceals a significant danger, because over time, these huge blocks of ice break and, when they fall, can damage the equipment or people underneath. In addition, a thick layer of snow creates an additional load on the roof and can damage it. To minimize the risk of such situations, it is necessary to ensure effective heating of the roof and gutters from Perth Guttering and Roofing by means of a heating cable.

Reasons for icing.

What factors influence the appearance of icing? The fact is that as soon as the temperature of the air in the roof acquires a positive value, the snow begins to melt and when it becomes water, it flows towards the edge of the roof and freezes almost immediately since outside the Temperature is below zero. This is the reason for icicle formation and ice accumulation in drains.

Another reason for the icing on the roof elements may be the use of an attic as a heated residential room. In this case, the temperature inside the attic space is almost the same as in the house. As a result, the roof is heated enough to melt the bottom of the snow. Leaving a warm place, the water freezes outside.

Whatever the reason, action must be taken.

Materials Required

It should be taken into account that additional heating measures require not only metal roofs (metal tiles, roofs, etc.), but all others because a similar problem can occur in the roof of all currently available materials.

Any work can be done independently and with the participation of specialists; The decision is made by the owner of the house. In principle, the installation process itself is not too complicated from a technical point of view, but the problem is that the heating of the roof, as well as the gutters, is carried out by means of special cables, and its length and resistance depend directly, It requires quite complex calculations.

Pay attention to avoid the occurrence of abnormal situations and better results, it is better to leave the calculations to the professionals.

As there are several types of heating cables, we will discuss the characteristics of each of them.

Resistive Cable Heating Device
As the first material suitable for heating work, a resistive heating element consisting of a conductor and insulation can be mentioned. The principle of its operation is based on the fact that the heating core has a fairly high resistance, as a result, when an electric current passes through it, the cable is heated to the point that it is able to melt the ice around it.

Pay attention The dependencies between the resistance of the material, the length and the heating temperature of the cables are stable, which allows them to be calculated in advance so that the element is heated enough to melt the snow, but does not melt the insulation.

As the undoubted advantages of using a resistive cable, it is possible to observe the simplicity of working with it and its high reliability. Such a system is a closed circuit. Everything is calculated in advance by professionals and it only remains to fix the cable in the right places.

Pay attention The length of the resistive cable cannot be changed independently.

It is also worth adding that during the operation of the resistive cable, heating occurs all the time and with a constant value. That is, if you mount such a system, there will be two main modes (on / off), which means you will need to constantly monitor, you must turn on the system or it is not necessary. In principle, this is not so difficult, but the constant lack of time that accompanies current life can make adjustments. It is true that you can automate the operation of the system by installing a thermostat, but this will require additional costs.

Another material used in roofing works is a self-regulating heater. Your device is somewhat more complicated than the one of the previous analog since it also includes a special cover for heating and also (so that everything works without problems) the installation of several sensors and distributors is required.

The self-regulating cable (unlike the resistive one) consists of several braids. All this, in combination with temperature sensors and special regulators, makes independent system operation possible. Such heating will turn on when necessary and turn off if not necessary. Not only will this prolong the life of the device, but it will also have a positive impact in terms of energy savings.

Assembly work

When installing heaters for ceiling elements, complex calculations are required, with respect to cable length and resistance, which is best left to experts. But the installation of the system itself can be done by yourself. For these purposes, special fastening hooks are generally used, which hold the conductor to the ceiling. This is done, as a rule, at the bottom of the roof, because it is in this place where ice formation occurs most frequently. The conductor is placed in a waveform around the perimeter of the roof and fixed.
