How to cover the roof with iron

The choice of material for the roof takes into account the individual characteristics of the building: the angle of inclination of the roof, the solidity of the foundation, the overall architectural style. When choosing a topcoat, sheet metal is often preferred. This material ensures the durability of the roof, has a low weight and does not weigh down the structure, the processing and installation of metal is not difficult, which speeds up the whole process of roof construction. In this article we will look at how to cover the roof with iron.

What type of roofing iron to choose?

Metal sheets for roofing differ in appearance and coating.

• Ferrous iron - sheets or rolled steel without coating, is resistant to mechanical stress, but does not tolerate moisture. This is a budget material, but for long-term operation requires anti-corrosion coating.

• Galvanized steel - has a smooth surface, resistant to atmospheric precipitation due to a protective layer of zinc, indispensable for the device fold roof.
• Profiled metal - galvanized iron, profiled to create stiffeners. It has a trapezoidal, undulating or rectangular cross-section. After treatment with a polymer coating, the anti-corrosion and aesthetic properties of the material increase significantly.

Stages of installation of the roof of galvanized steel

Before you cover the roof with iron, it is necessary to make a solid crate, which will eliminate metal deflections. The basis for the iron sheets are wooden bars, located 20 cm apart, a continuous crate of cut boards or a step-by-step crate of boards nailed 10 cm away.

It is possible to join the sheets with zinc-coated iron by overlapping them and fixing them with nails with a special pad, or in a more labor-intensive and reliable way - by folding. To perform the work required:

• wooden kyivanka;
• scissors for metal;
• workbench for painting pictures;
• metal hammer;
• crest bender;
• roulette;
• mixture of drying oil with red lead.

Iron sheets before starting to ground with a mixture of linseed oil and red lead to increase the corrosion resistance. Dried iron is cut into pieces of the desired size, for this purpose, metal shears are used (the Bulgarian is strictly prohibited). The faltsevy way reliably protects joints from course. It is a combination of adjacent sheets of iron in the lock, made by bending the edge.

For horizontal joints, recumbent folds are made. They are made using special machines or on workbenches using a hammer and a mallet. At the edge of the sheet, they draw a line and bend the edge with a mallet; for this work, you will need a workbench with a metal corner. On another sheet, the edge is folded several times, before creating the U-shape. The joint is sealed and bent against the metal sheet. In this way, blanks for laying on the roof are formed; they are called paintings.

On the roof, all the paintings are connected with the help of longitudinal standing seams. In their manufacture using combbib. Before you start mounting checked the location of the sheets in the vertical plane. The length of the workpiece is recommended to be equal to the size of the roof slope. The paintings are laid in rows from the ridge to the chute. For consolidation of lying seams the steel strip is used.

In places requiring special strength of seams, use double fold. It is made by bending the edges of two sheets, followed by simultaneous folding. The recumbent fold is installed bend to the eaves, this allows water to flow freely along the roof. The paintings are fastened to the crate with metal clips.

The most difficult step is the design of the collar for the chimney tuba. It is made in advance, according to the shape and dimensions of the pipe. With metal sheets the collar is connected by standing seams.

To understand how to properly perform the installation of the roof, using a folded joint, it is worth watching a video with the recommendations of professionals.

Features roofing profiled sheet

1. When deciding on the size of a corrugated sheet, choose a roof slope that is equal in length, if it is large, be guided by the convenience of transportation.
2. Counting the number of sheets, consider the angle of the roof, if it is within 15 to 30 degrees, you will need overlap up to 20 cm.
3. Before installation of a professional flooring the waterproofing film keeps within. It is fastened with brackets to the rafters. On top of it, counter rails are installed, providing clearance with metal sheets.
4. The polymer coating of professional sheets should not be damaged during transportation and installation, it will lead to the loss of anti-corrosion properties of the material.

Profiled flooring grades differ in strength and wave height. For the device of a reliable roof use two brands:

• NS - for roofs with a significant angle of the slope, not experiencing a high load;
• N - is used for a capital roof, differs in additional stiffening ribs.

Installation of a professional flooring

Professional sheets are easy to process, for stacking and fixing you will need a hacksaw and a screwdriver. Lay the sheets from the bottom up, starting from the right end. Solid profiled sheets are pre-fixed with a single screw and laid along the entire length of the roof. After aligning on the roof, the final fastening is carried out with roofing screws, the heads of which are selected according to the color of the polymer coating. Horizontally, they are screwed in with a screwdriver into every other wave, vertically at the distance of the crate. The upper and lower parts are fixed with a screw into each profile.

When using several rows of corrugated sheeting, their transverse joints are connected with an overlap of at least 20 cm and coated with silicone sealant.

When working with profiled iron, care should be taken to prevent damage during movement. It is recommended to wear soft shoes or make wooden flooring on the finished section of the roof.

Correctly installed roof of iron will provide reliable protection for many years, this good-quality coating resists under the action of precipitation and wind. The shiny or colored surface used by the metal sheets will complement the architecture of the building.
