After laying roofing material, take care of the removal of rainwater, which can damage the walls and the foundation of the house. Effective protection against the negative effects of precipitation are rain plums for the roof. About what they happen and how to correct the installation of a drain from the finished roof with your own hands you will learn by reading the article by the article.

Types of drain systems and their features

For the manufacture of rain plots, two materials are used: plastic and metal. Elements of the drain systems from metal differ by protective anti-corrosion coating. Used:

• zinc coating;
• plastic;
• imediate;
• coating with a layer of zinc-titanium.

Metal systems are characterized by high strength, but at the same time they are noisy and heavy (require the use of reinforced fasteners). Installation of them is complicated by the need for rolling elements.

Tip: In the case of applying metal drain systems, replacing rolling elements with sealing with silicone is not recommended. Over time, silicone is destroyed under the influence of external factors.

Plastic systems are not recommended to be used in case of significant snow load. They become fragile at minus temperature. Drain systems made of steel with a polymer coating have proven to be best: they are aesthetically attractive and resistant to corrosion. But it is important to correctly perform a plum mounting from the roof.

Drain Roof System: Design and Calculation

Designing the drain system is performed in conjunction with the design of the roof of the house. The following rules are followed.

1. It is necessary to determine the places of installation of the funnel. They are located on the edge of the system from the downgrade side. In the case of a large area and the length of the roofing slide, the installation of intermediate funnels is required at a distance of up to 24 m from each other.
2. If it is impossible to install intermediate funnels, increase the angle of the grooves of the grooves.
3. Depending on the area and configuration, the roof is chosen the diameter of the drainage: 80, 100 or 125 mm. The amount of precipitation in the region is also taken into account.
4. In order for draining water from the roof to occur effectively, the installation of the system is performed at the rate of: 1 m² of roof - 1.5 cm² chute sections.
5. Installation of the roof of the roof of heavy metals (from copper) is not recommended in the case of a fairy structure of light frame structures.

Plum System Mounting Technology

In order for the gutter to cope with the load and effectively assigned rain and melting water, the installation work should be carried out in compliance with certain rules.

1. The drain system is installed so that the edge of the roofing material hung over its axial line.
2. The chute must have a bias towards the funnel.
3. Fastening brackets is performed using self-tapping screws.

Methods for fastening brackets

1. On the base of the roof (before laying roofing material). The best option for metal systems.
2. To rafal legs. It is more convenient to complete the roofing material before mounting. Recommended for light plastic systems.
3. Installation on the end board. It is used exclusively with plastic chutes and brackets intended for installation in a vertical position. Can be used in low-level areas.
4. Fastening to the wall of the house: possible with small overwhelms of roofing material.

The last two options can be implemented after the end of the installation of the rafting system and roofing pie.

Installation of plastic roof plugs

To work, you must have at your disposal the following set of tools, devices and materials:

• pipes and gutters;
• drain funnels;
• couplings for connecting elements;
• silicone sealant;
• plastic glue;
• seals;
• plugs;
• brackets;
• electric or perforator drill (depending on the method of fixing brackets);
• screwdriver;
• hoven for metal;
• self-tapping screws (for mounting brackets);
• clamps for fastening pipes and funnels.

Plums for plastic roof are installed in compliance with the following rules.

1. Before starting work, the number of necessary materials is determined.
2. Brackets are attached: holders are installed at a distance of 0.5 m from each other. The bracket must have a slope. To do this, the cord is stretched from the top point to the bottom, in the direction of which the details of the drain system are oriented.
3. The gutter is connected to the allen at least 25 mm. The same distance should remain between the edge of the roofing sink and the outer side of the gutter.
4. The gutter is fixed to the bracket, sealing the place of connecting elements using the sealant. If necessary, plastic cut the metal with a metal.
5. Fasten a drip to the rafters: it is necessary to remove moisture from under roofing cake.
6. If the gutter system has turns - the angular elements are installed. The upper and lower edges of the system are limited to dead-end plugs (if the mounting of the funnel is not provided). Fixation is carried out with glue.
7. Pipes and funnels are fixed with clamps.
8. The lower edge of the pipe should divert water from the foundation - to the drainage system.

Important: during the installation of pipes and funnels, the connection should not be kept due to glue. The fixation is carried out by a dense entrance of the matel parts of the parts in each other.

How to care for the drain system

In order for rain and thawed water to be unhindered from the structure, it is recommended to perform the following.

1. The drains and funnels can be clogged by leaves, water accumulates in the grooves. Freezing, it can damage the system. To avoid this, the gutter is periodically examined and cleaned from garbage and leaves.
2. Special grids are laid in the gutter on top of the funnels: they will not allow the leaves to get into the system.
3. The laying of heating cables is recommended: this contributes to the effective operation of the drainage system during the melting period.
4. In order for the brackets and gutters during a ridiculous supply of snow, snowstores are installed on the roof.
