Sewer systems are needed virtually any roof. They protect the outer walls and basement from water, the foundation - from excessive moisture. Thanks drains water from the roof is collected and sent to one place, and the building is not threatened premature failure. In addition, the system can be as decorative, to emphasize the transition from the roof to the walls of the gable to the front. This house will look stylish and elegant. The most common materials for gutters - PVC, galvanized iron and copper. System of PVC each year are enjoying increasing popularity. Their undoubted advantages are: - complete absence of corrosion - almost complete silence in the rain - resistance to natural influences, including UV rays - frost resistance - resistance to chemical attack (acids, hydrocarbons). The disadvantages are: - to change the linear dimensions of the sudden temperature drop - to combustion instability (at the same time, plastic is difficult to ignite and stops to melt immediately after the removal of fire) - smaller than that of metal, resistance to mechanical stress. The service life of plastic guttering is about 50 years and depends largely on the installation and the environment. System made of galvanized iron are less durable than PVC. Without the special coating after 6-8 years of zinc layer is destroyed and the iron starts to corrode, reducing the life of drainage and spoils the appearance of the building. To avoid this, the system is covered with enamel or lacquer on metal, designed to work outdoors. This drain will serve more than 30 years. Iron - the material is fairly durable, can withstand high mechanical loads, are not afraid of him, and winter conditions. For example, under the pressure of the ice may crack the plastic, iron - only deformed. Now produce drainage design from a sheet of galvanized steel coated with the polymer. They are distinguished by reliability and durability - up to 100 years. In addition, they are resistant to: - mechanical stress - repeated bending - Fire - environmental influences. Undoubted advantage are also easy to install and no additional seals (as opposed to made of PVC, which require the use of glue or rubber seals). Copper gutters are very durable and possess all the qualities of metal. However, they are much more expensive than plastic and steel. Price per meter copper gutters on average $ 16, a pipe - $ 26, while the trough of galvanized steel with polymer coating costs about $ 6 tube - $ 8. Plastic gutters and pipes would cost about $ 1-2 cheaper than steel. The cost depends on the manufacturer, the size of the elements and the number of components. Rainwater systems differ from one another design. Produce designs with rectangular and circular sections of different colors. Material of construction of the roof, in general, does not affect the choice of the system. At the same time, experts advise to pick up gutters and roofing of the same company that will pick up and perfect color, and mounting. However, you can install and gutters of different companies, as they are all similar in structure. Mandatory elements of systems gutters are gutters, hoppers, pipes, elbows, guttering, brackets for attaching gutters and pipe clamps. The more parts, more opportunities to establish the optimum system. This is especially important if the roof of a complex configuration. The construction is mounted on the perimeter of the building. Drain ordered, with a detailed description of the parameters of the building to which it will install. Particular attention should be paid to: - relief and catchment area of ??the roof. First, calculate the surface area of ??the roof - the capacity of the system, the main indicator of which is the diameter of gutters and pipes, the number of sinks, as well as inclination and length of the gutters. The total number of runoff is calculated based on the surface of the roof and the location of sewers - the length of the eaves, where they will establish a system crash cornice. Proper installation - the basis of optimal functioning drainage system. Improperly installed drain can not perform its function, leading to flooding of adjacent to the home area, for example, if the area of ??the roof does not match the size and number of gutters and pipes. Before you proceed, make paint roof boards end: after fixing gutters access will be restricted. Trough mounted immediately after the device crates, but before the roof covering, as the brackets gutter is attached directly to sheathing. Drainage pipes installed after the roofing work. If the roof is not completely changed, use the shorter brackets, through which gutters are fixed on the end. A necessary condition for such an assembly is a stronghold end, otherwise the system will not hold. Keep in mind that gutters made of PVC and metal are assembled in different ways. This is due to the fact that the length of the elements of the drainage system of PVC under the influence of the temperature difference varies. It is used fittings to compensate for changes in length of gutters and pipes. When assembling systems from the metal fittings are required. In addition, when you install gutters made of PVC and metal between the brackets that attach the gutter to make different distances. In plastic systems, it is no more than 60 cm, while the metal - no more than 90 cm Linking individual elements gutters made of PVC can be either adhesive manner, or with rubber seals. Combine these two methods is unacceptable. Thus, new gutters have more design features than metal. Installation of drainage would cost now at $ 8.10 per meter, depending on the complexity of the work and structure of the roof. The price is usually fixed and not dependent on the value of the material. Gutters should not fall under the wave sliding down from the roof of snow. To ensure the security of the system drains, roof snow guard set special - different for each type of roof. For example, for metal can be attached tubular snow guard, and the life - ethmoid. Another major problem that occurs in winter - ice drainage systems which also leads to their destruction. Extend the life of the roof and gutters, you can use a cable de-icing systems. At its core heating cable that plugs into a place where mostly formed ice and icicles. An important property of the cable to heat the roof is the resistance to ultraviolet radiation. There are two types of cable: - resists (a simple heating element which has the same structure as that of the spiral of domestic boiler) - self-regulating (in a special semiconductor matrix actively affects the temperature: when it's cold outside, the matrix has a negative temperature and consequently increases power of work, with high temperatures, the power cable is reduced). Resist the cable costs about $ 4 per meter, and self-regulating - $ 15-20. The kit also includes temperature controllers, sensors, water and sediment, fastening material and the control cabinet. These systems operate automatically: applies only when there is water in the gutters at a temperature of -10 to +5 ° C. Anti-icing system installed on any roof, they do not require dismantling of the summer. When installed in the building structure can not be touched. Important issue - the clogging of drains with leaves and needles of coniferous trees. Leaves from falling into the funnel chute protects a special grid. However, it retains only the larger leaves and needles are not an obstacle. Clear the drain will help professionals, whose services cost $ 200-300 depending on the complexity of the system. Thus, the gutter is a versatile design, providing for collection and drainage of water from the house, and is an important decorative element. The system substantially increases the service life of not only the roof but the building itself.
