We are going to talk about the types of roof gutter systems. But what is a gutter system
? It is an integral part of the roof of any building. According to it’s constraction, it is internal and external. Structurally, it includes a number of parts like pipes, gutters and hoppers. Also turns, elbows and other accessories.
There is a variety of different materials that are used to make these elements. We understand that it is difficult to choose the right type of drain from the range of products that ara available. In the next section we will present you the different kind of metal roof gutter systems, in order to help you decide the best for your needs. We are going to carefully compare all the features of the metal systems offered on the market.
Metal types of roof gutter systems
By definition, it is impossible to get rid of the rain or melt water. Residential and non-residential buildings must have a way to protect itself from their effects. If they can’t their construction elements like the walls, the roof and foundation will not last for long.
If there is no gutter system on the roof, then not only the exterior finish, but also its supporting structures will quickly begin to collapse. Better to spend money and Make an effective drainage since then you reviewed the whole building.
All elements of the gutter sewer, according to the construction
material can be divided into two major groups:
The metal group includes these products that are made of steel, copper, or even zinc and aluminum. The second ones that we are not going to talk about is the one of PVC, meaning the polypropylene and polyethylene. Each one of these materials has its own advantages and disadvantages also.
Shortly, galvanized gutters or coated with polymer steel, unlike the plastic ones, does not change their geometry in the sun and does not explode from the ice that freezes inside. The copper and zinc elements of the sewer will last longer, but they are also the most expensive. Plastic drains are distinguished by a variety of colors and low cost.
However, the choice of material for the construction of the roof overflow system depends to a large extent on the configuration of the roof, the amount of rainfall and the average annual temperature in the area where the building was built.
Before you go to the store to buy a sewer, you need to study all the nuances of the proposed options. In some cases, you can do it with cheap plastic, while in others it is better to get something made of metal.
Characteristics of metal systems
Gutters are made of zinc and copper. However, the first metal was very sensitive to corrosion and short-lived, while the second was very expensive. Zinc, if used now, is only in the form of titanium alloy. Most often it is used only for galvanizing steel.
They are steel gutters and pipes mainly offered by sellers when a buyer asks to show a metal drain.
The classic galvanized gutters
Steel products are the most affordable version of a metal drain. They are made of cold rolled steel, which is coated with a layer of zinc.
These eastern systems have a long service life (if the zinc coating is not damaged), UV resistance and extreme temperatures. They can withstand large amounts of snow without breaking without breaking in winter.
To give the gutter structure a more visible appearance and increase its service life, galvanizing is coated with polymers:
- Pural (PUR)
- plasticizer (PVC, PVC)
- polyester (PE or MPE)
The investment from Pural is resistant to mechanical damage, UV and belongs to the middle price range. A steel
gutter will last 30-35 years without replacement.
Plastisol (polyvinyl chloride) is distinguished by a wide range of colors and low cost. However, under the influence of UV rays, it softens and deforms. Its lifespan is up to half a century, but not in the southern regions with high solar radiation.
Regular polyester (PE) is cheap, easily tolerates ultraviolet radiation, but is easily scratched even by ice. This coating will last 10-15 years. Then the protection will disappear and the moisture will start destroying the steel base. It has a more durable analogue with the addition of Teflon – MPE. However, unlike PE, this color choice is limited to shades of gray only.
If the roof is metal, then the elements of the eastern system are better selected from a similar material with the same layered structure. Thus, the life expectancy before the repair will have a common, the replacement of the roof and drains can then be done together at the same time.
Aluminum Zinc type gutters
Galvalyum is called a steel coated with an alloy of aluminum and zinc (Al + Zn) with the addition of silicon. This material surpasses conventional galvanizing several times in heat resistance, coating resistance and corrosion resistance. It is not afraid of acid rain and ultraviolet light.
And to hit, you have to try hard. Snow and ice can not hurt him. Zinc has a higher electrochemical potential compared to iron. As a result, it gradually “dissolves”, leveling only the oxides that begin to form in the steel. Corrosion simply can not pass through such a protective layer on the base metal.
Gutters from titanium zinc material
This alloy is also inherent in high rates of strength and corrosion resistance. It consists of titanium, copper and zinc. The first metal is responsible for reducing corrosion sensitivity, the second for ductility and the third serves as a base.
These metal gutters can be placed on roofs of any shape, they bend without problems, without breaking. Water is not afraid of titanium-zinc, it is an ideal alloy for the construction of drains. The main problem is the sensitivity to electro-corrosion. In contact with copper or iron, it inevitably begins to collapse. And almost nothing can be done about it. All that remains is to exclude such contact. If the roof is covered with copper sheets, then the drain is better to take from another metal.
Compared to steel, aluminum gutters are lighter and less susceptible to corrosion. The lightness of the metal allows the walls of the pipes and gutters to become thicker. At the same time, such a drainage system does not load the connectors unnecessarily, but can withstand significant loads of snow, ice and water.
Aluminum calmly tolerates frost, sun and mechanical shock. It is durable, but noisy and relatively expensive. If the cottage has low sound insulation, then every drop of rain that falls on a similar sewer system will sound perfect inside.
Aluminum gutters are often covered with polymer paint by manufacturers. This increases the corrosion protection and allows the product to be stained from the RAL list. For the roof of the house, you can choose the aluminum elements of the drainage system as a noble silver shade and with any other color. In this respect, aluminum outperforms many metal competitors.
The copper drainage gutters is a combination of luxury and aesthetics on the outside of a private home
. It will cost a round sum, but with proper installation it will take as long as the building itself will stand. Copper is wear resistant, durable and does not deform in heat or cold. The scratches and a natural patina only give it elegance. And it is completely indifferent to ultraviolet radiation.
Using a metallic gutter system of copper reflects the refined taste of the cottage owner, as well as his financial viability. Such a drain is worth a lot of money. Not for nothing that all products from this metal belong to the elite category. But then the copper drainage system on the roof will surely last more than a hundred years.
