MELTING OFF ON EAVES, PORCHES AND BIGGER ROOF SURFACES (TCPR)
There are often problems on roof constructions with a projecting eave. The snow melts on the roof due to a heat leakage and the water comes down to the base where it gets cool and freezes.
On porches there is often falling snow coming from roofs higher above and thus they get overloaded and the construction might give away.
Today the architects more often use glass cupolas on roofs when constructing new buildings in order to get brighter and nicer rooms. There is a heat leakage from the cupolas, which makes the snow melt and come down on the roof where it freezes and a bank of ice is formed around the cupola.
These and other disruptions in the functioning and accident risks due to the construction of the roof can be avoided if heating cable applications are installed, which will keep the roofs clear from snow and ice.
