The drain system includes a gutter, water collectors and drainage pipes. The sets differ in the size of the elements and, of course, the larger the dimensions, the more water they can skip during the rain. Only now, advise something optimal, is very difficult. Who can know what intensity the downpour can fall at home? Who is known.
Distribution systems differ only in materials, and, consequently, the price. Copper sets are very attractive. Soft and beautiful metal, unlike other metals, is not afraid of temperature extensions at the joints of the pipes and it does not require special rubber gaskets in these places.
For the drain, the spring is very dangerous when ice blocks can fall from the roofs. Special protective fences somehow still save from the ice, but from the icicles that are formed on Ratoka, and the fences do not save.

Roof heating is the most effective, although expensive means of protecting roofs from ice and icicles. Many people believe that heating may only be required in the spring, during the period of melting snow. However, practice indicates that the melting of snow can begin even at a negative temperature of 15-20 degrees due to the heating of the roof from the inside. The complexity of the heating system is explained by the fact that on the roof, depending on its design, there may be a lot of places in which ice can form. Therefore, the system of power and signal cables is very branched. The system includes sensors that provide automatically turning on and disconnecting the system. The house must create a separate heating control panel. Approximate energy costs per 1 m2 of the roof area, which must be heated, amount to about 200 watts, and in the lattices and pipes for heating requires 70 W/m.
