Our main protector from harsh weather conditions is the roof, and in order for it to fully perform its functions, it is necessary to select the right materials for the roof. As you know, they are divided into many types, one of which is sheet roofing materials. We will talk about them.

Types of sheet materials

To begin with, we will outline in general terms what sheet materials exist, after which we will consider in more detail each of the types.

There are 7 types in total:

1. Professional list
2. Metal tile
3. Composite roof tiles
4. Corrugated bituminous sheets
5. Light-transmitting sheets
6. Asbestos-based (slate).
7. Seam roof

And now, after we have learned all the types, it is necessary to consider them in more detail. Learn about their properties, advantages and disadvantages.

Corrugated board

The first type of sheet material is flat metal sheets. Their use is possible only in cases where the roof slope is at least 12 degrees.

The material itself is attached with the help of special anchors to the base (accordingly, it requires the arrangement of the lathing. The sheets are made of galvanized steel, additionally covered with several layers of protective compounds, and can also be painted.

They are presented on the market in several forms:

1. Straight sheets.
2. Plump.
3. With a triangular profile.
4. Rectangular profile.

Similar are used in various fields, from residential buildings to production sites. But the greatest popularity was gained when arranging the roof of industrial buildings, as well as outbuildings.

Advantages:

1. Long operational period, which reaches 50 years.
2. The material is easily assembled, which allows you to do all the work yourself without involving specialists.
3. There is also a high level of strength.
4. Low cost.

Disadvantages:

1. The material is quite noisy, which requires additional soundproofing.
2. It is also worth considering that this is metal, respectively, additional thermal insulation may be needed if the roof is located directly above the living space.

Metal tile

The material is made up of solid sheets, the surface of which imitates the pattern of perfectly laid tiles. The use of such material, in comparison with conventional tiles, significantly reduces labor costs during installation, since the number of seams on the surface is significantly reduced.

The sheets themselves are made of an aluminum base, or galvanized metal. It is also noted that all the textured parts of the sheet are absolutely identical and completely repeatable.

It is also noted that there is no uniform sheet size, therefore, depending on the situation, the buyer can choose the required size of the material himself. The width of the sheet is generally 1.1 m, while the length can vary from 40 centimeters to 8 meters. In addition, the tiles themselves are 6 times lighter than their natural counterparts.

When laying, a slope of at least 12 degrees is required. Fastening is carried out in the same way as in the case of corrugated board, using screws to the crate. At the same time, no pre-drilling of holes is required.

The sheets themselves overlap each other, while laying on the old coating is possible, without dismantling it.

But it is worth noting a significant drawback, this is the noise of the flooring during rain, snow or hail.

Composite roof tiles

The material is somewhat similar to ordinary metal tiles, but you should not confuse them, there are a number of significant differences.

First of all, the composite material has a constant size, namely 1 * 0.5 m. In addition, the coating is made only of galvanized steel, and the top is covered with an aluminum alloy. Additionally, protective compounds and mineral granulation are provided, which gives the appearance of a natural tile.

Among the advantages of the material:

1. Not flammable.
2. Provides good sound insulation.
3. It is lightweight.
4. Good aesthetic qualities.
5. Huge assortment of shapes and colors.

Among the disadvantages:

1. High price.
2. More difficult and time-consuming installation than standard metal tiles.

Bituminous sheets

They are rather flexible sheets of a wavy texture. They are made from cellulose fibers, which is further impregnated with bitumen mastic.

Later, after manufacturing, the front side is additionally covered with protective compounds and paint. Based on vinyl and acrylic polymer segments.

Today, a fairly large number of companies are engaged in the production of such materials. And accordingly, many new variations appear, one of which is cardboard bituminous sheets.

Ondulin

The main one, as the name implies, becomes cardboard, in the future it is impregnated with bitumen and tamed with a decorative layer. Such sheets are called ondulin. The appearance of the material strongly resembles slate, but unlike it, it has a number of inherent advantages:

1. Not fragile.
2. Much easier.
3. Has other sizes.
4. Does not emit harmful substances.
5. This material is durable
6. Durable
7. Economical
8. differs in relatively low labor intensity.

Parameters of one sheet: weight - 5.7 kg, width - 950 mm, length - 2000 mm. The service life of ondulin is quite long - 50 years.

One of the main advantages of this material is environmental friendliness, since it does not contain asbestos, and resistance to negative environmental influences.

The material itself is recognized as one of the lightest among all roofing coatings.

Ondura

Another variety is noted Ondura - sheet material, in the manufacture of which bitumen and cellulose cardboard are used. From the outside, the sheets of ondura are covered with a layer of special paint. During installation, it is required to lay an additional waterproofing layer from roll materials. The service life of the ondura, in comparison with the usual slate, is less, and the artistic and decorative indicators are much higher.

They are made from polycarbonate or polyvinyl chloride. This material is distinguished by rather high decorative properties, but its service life is relatively short - 10-15 years.

Light-transmitting sheets

This material is made mainly of polycarbonate or polyvinyl chloride. The production technology is based on extrusion.

The material is gaining a lot of attention due to its design solutions that allow you to create unique buildings. At the same time, a short service life is noted, up to 15 years.

Asbestos cement sheets

The starting material for them is ordinary or colored cement with the addition of asbestos fibers.

The qualitative characteristics of asbestos-cement sheets are:

1. durability
2. ease
3. strength
4. waterproofness
5. fire resistance
6. high resistance to alkalis.

Flat asbestos-cement sheets are produced from unpainted raw materials to which pigment is added. They can be:

1. light (uncompressed)
2. heavier (pressed)
3. smooth
4. painted with enamel
5. embossed.

Flat asbestos-cement sheets can be 1200, 2500, 3200, 3600 mm long, 4, 5, 8, 10, 12 mm thick, 800, 1200, 1500 mm wide.

When installing the roof, the sheets are laid on a solid crate diagonally overlapping

If it becomes necessary to cover slopes and edges, the sheets can be cut into pieces of the desired size. To make the roof more reliable, roofing board or glassine is often laid under the asbestos-cement sheets.

Corrugated asbestos-cement sheets of an ordinary profile can be ordinary, having the following parameters: weight - 8.5 kg, thickness - 5.5 mm, area - 1200 x 686 mm, or reinforced with a thickness - 8 mm, area 1000 x 2800, wave height - 50 mm. Corrugated sheets in comparison with flat ones have a much higher strength due to the stiffness due to their cross-section.

Slate features

When constructing a roof covered with such material, the device of a continuous sheathing becomes optional.

The standard size of corrugated sheets with a thickness of 5.5 mm is 1200 x 680 mm.

The mass of ordinary slate is 8.5 kg. In addition to it, a reinforced one is also produced, products from which are even more durable and durable.

The industry, in addition to sheets, produces grooved elements for covering the ribs and ridge of the roof.

There is also plastic-based slate. The differences between the roofing made from it are lightness and various colors.

The pressed boards are very durable due to their corrugated undulating surface.

The dimensions of the slab are 1000 x 1095 mm, its weight is 11.5 kg. During the production process, it is painted in standard colors: black, brown, red, gray.

Seam roof

And the last option for covering is a folded roof. Like many other sheet materials, it requires a tilt angle of at least 12 degrees. The material itself is made from various components:

1. Metal.
2. Copper.
3. Zinc.
4. Cink Steel.

The sheets are fastened together with the help of folds, which are made manually at the work site. Quite often, it is the variants of products made of zinc, copper and titanium that meet in production. Therefore, some varieties have received the name "Titanium zinc sheets".

Another variety is copper sheets, which are the most popular. The disadvantage is the rather high cost, which leads to a low percentage of popularization.

Such sheets are able to emphasize the expressiveness of the building and its architecture.

Among the advantages:

1. Long operational period (over 100 years).
2. Good flexibility and elasticity.
3. High level of durability.

Among the disadvantages it is worth noting:

1. High cost.
2. The material fades over time. At first, a bright copper color is expressed, over time it begins to darken, and after a few years it acquires a kind of bluish gray tint.

Conclusion

As you can see, each of the materials has its own properties, which can be useful in certain conditions, and not needed in others. Therefore, the selection of the type of sheet material for the roof should be done based on the characteristics of the region in which you live, as well as depending on the financial situation. And in conclusion, we suggest you watch a few videos about sheet types of roofing materials.
