How to choose a drain system for the roof?
The drainage systems are installed in order toThey diverted rainwater and melted snow from the roofing material. The withdrawal is made to a special place in the catchment area. Such systems are absolutely necessary absolutely for any type of roof, because excessive moisture falls on the basement, walls and foundation of the building, destroying them and causing dampness. Proper installation and properly selected drainage system will allow you to forget about problems with dampness and moisture for ever, leaving your walls dry and warm. In addition, a building with a drain, which is in harmony with the architecture of the house, color, facade and other elements will help to emphasize the design of the building and give it a more aesthetic appearance.
To date, the water diversion is divided into two types - plastic and metal (copper, galvanized steel, steel with a polymer protective coating). Before , consider these options in more detail.
Plastic drainage systems
Plastic is a universal material. Its main advantage is that it is not exposed to the destructive effect of corrosion and is resistant to alkaline environments. The material has excellent resistance to temperature changes, and can withstand running from -50 to +50 degrees. Manufacturers of plastic pipes tried to make the material almost non-combustible, and it easily withstands heavy loads, but only under conditions of positive air temperature. The installation of a plastic drainage system is very simple, the pipes are connected together with a special glue or sockets - connections with a rubber seal. Plastic does not require special care, and its slippery surface allows the pipe to not clog. Such systems of any colors and forms are issued. The service life is approximately 25 years.
Metal drainage systems
Systems of galvanized steel or with the presence ofpolymer coatings are not corroded. Also, there are copper systems that have excellent decorative properties. They have a wider temperature reserve, and can withstand -50 to +110 degrees. More complex installation is due to increased strength. Produced in two forms - round and rectangular shape. The color palette is more diverse, so if you do not find the right color in PVC systems, then you will definitely find it in metal systems. The service life of these pipes is more than 15 years.
Copper Drain Systems
Installation is made by soldering. Despite the high cost of a reliable system, it will last you for quite a long time - up to 150 years!
Do not forget that the drainage should be selected together with the roofing material, and is also not small.
