Roof draperies, metallic: installation. Roof gutters, metal, galvanized

Water from the roof should be diverted so that it does not fall on the facade and foundation. For this purpose, gutters for a metal roof are predominantly used. Mounting them is not a problem if the roof finish is done correctly and there is a reliable and solid foundation. In addition to the designated purpose, modern drainage structures perform a decorative function. Their color is selected so that it is in harmony with the facade or roofing.

Gutter system composition

The system includes:

• Gutters;

• Pipes;

• Plugs;

• Funnels, knees;

• Turns;

• Mesh for protection from debris and leaves;

• Fastening elements (pins with clamps, brackets, connectors of gutters and pipes).

Roof gutters are galvanized metal, with polymer coatings of different colors, they are used most widely because of their durability and strength. The most reliable are copper products, but they are much more expensive.

Selection of the design of the drainage system

1. Flat roof

Gutters differ depending on the type of roof. If it is flat, then it is possible to use drainage funnels, which are inserted into the openings of the floors. Through them the water goes down the pipes. The method of internal precipitation is preferable for areas with a cold climate. They go into the storm sewer system.

On the edge of the roof can be mounted drip, which provides a drain into the gutters. When erecting a flat roof, small inclinations to drainage points should be provided. If there is a parapet through it, the water goes right through the scappers - the roofing horizontal funnels. With them are connected pipes, located outside.

2. Sloped roof

For sloped roofs, external gutters for metal roofs are used. Their installation is carried out with the installation of gutters. This option is most often encountered.

Drains for the roof are metal. Price

The dimensions of pipes and gutters depend on the area of the roof with which water flows. The table below will illustrate this.

Dimensions are selected according to the area of the largest ramp. Brackets for metal gutters are located in steps of 500-600 mm. The chute tilts at an angle of 2.5-3 mm / m. One pipe passes through sediments, collected by a chute no longer than 10 m.

The number of funnels and pipes will be the same, and the turns are calculated depending on the complexity of the facade. The clamps are 2-3 pcs. On one pipe. If it is composite, then each site should be attached separately. In the joints, clamps are always installed in addition.

In a specialized building store, you can pick up gutters for the roof of your house metal. Their price will be slightly higher than plastic ones. For the metal, it is 200-400 rubles per meter. Products made of copper look beautiful, but have a high cost and are intended for elite houses.

The cost of plastic varies widely, depending on the quality.

Advantages of metal gutters

These products are characterized by such qualities:

• High strength during operation, especially under the influence of snow and ice in the winter season;

• Small changes in linear dimensions with temperature fluctuations;

• Roof gutters galvanized metal has high corrosion resistance also due to the presence of additional polymer coatings;

• At low and high temperatures, their strength does not decrease, while plastic structures in the cold become brittle;

• Do not fade under atmospheric influences;

• Does not burn and does not deform from heat.

Disadvantages in comparison with plastic constructions

There are some drawbacks in metal gutters:

• Higher cost;

• Easily formed scratches;

• Noise in the rain;

• Due to the fact that the weight is larger, reinforced fastening elements are required;

• It is more difficult to install gutters for a metal roof. Installation is particularly difficult for rectangular profiles, where riveted connections are required.

Gutter installation

Installation of metal gutters is made at height and requires the use of scaffolding, scaffolding, ladders.

Gutters can be hung on hooks along the ledge. This design is called pendant. Installation can be done by yourself. On the seamed roofs, wall troughs are used. Usually they are installed by roofers when they cover the roof.

The system is installed before the roof is applied waterproofing and roofing coatings. Brackets are installed in accordance with the slope. First, the extreme ones are exposed, and then the rest (by a stretched twine). Through the crate to all rafters must be attached brackets, which will carry the main load from the gutters. The remaining hooks will also perform the support function. When laying rafters with a large step, you should find a way to strengthen the troughs. In winter and spring time, they significantly increase the load from snow or ice. If it is removed mechanically, then it is possible to damage the coating. The best way is to use a heating cable, which makes it possible to melt the accumulated ice.

To install the funnels in the gutters, holes are cut out and the edges are bent downwards so that garbage does not cling to them. This work is done on the ground. Cutting sheet metal with an abrasive disc is not recommended because of overheating of the edges and subsequent corrosion. But most people do. Therefore, cut edges should be covered with a primer and paint. Nevertheless, it is necessary to cut thin metal with scissors, since sparks destroy the polymer coating when using a bolgar. After that, a funnel is put on the funnel, which is fixed on it, and then the whole assembly is mounted on brackets and fixed. A mesh is installed in the drain hole, protecting the pipes from clogging with debris. It should be checked every year and cleaned of contaminants.

The angle is fixed to the chutes by special connectors. In this case, it is suspended on two separate brackets.

The main requirement of installation is the tightness of the system. When collecting gutters in the direction of incline, each following is embedded in the previous one with an overlap of 20-30 mm. Additionally, rubber seals or sealant can be used. To protect against debris and leaves, the trough is closed with a mesh called a "spider".

Before installing the pipes, first clamps are attached to the walls of the house. At the bottom there should be a drain knee, the distance from the blind is 30 cm.

If water flows down from the valley, then under it is installed a catchment funnel, which is fixed to the cornice and inserted into the pipe.

Rectangular metal gutters are connected together by means of rivets. Similarly, angles and plugs are attached to them. The use of seals in compaction points is mandatory.

The principle of the system is extremely simple and consists in the fact that the running water from the roof enters the gutter, then drains into the pipes through funnels, and then goes to the drainage system or tanks. The area near the house and on the site should not be washed out at the same time.

Conclusion

The most popular for our regions are drains for metal roofs. Mounting is a high price, they enjoy a higher demand compared to plastic because of their high strength and durability.
