Pros and cons of metal and Ondulina - make a choice

final stage of the construction of the roof - cover its roofing materials.At present, the choice of these materials is extremely large - from the cheapest to the elite and very expensive.However, the most popular roofing materials average price category.When choosing a roofing buyers are often the question arises: which is better, metal or ondulin?

Both of these materials are durable enough to have elegant appearance and easy to install.Because of these qualities, they are very popular among developers, and the choice of "metal or ondulin" depends only on the structural features and personal preferences.And metal and ondulin have a number of features that can influence the choice of roofing.Below are their features, advantages and disadvantages.

Features metal

Metal - a roofing material is profiled from sheet metal, simulating the shape of the traditional ceramic tiles.Iron sheet 0.45-0.55 mm thick was passed through a specially shaped rollers, then coated with first zinc, then the polymer dye.As a result, the metal sheet has a double protection: zinc anode provides protection for iron, shifting the process of galvanic corrosion over, and polymer coating protects against damage himself zinc.This double coating is resistant to scratches and small in the event of damage is easily repaired by applying the appropriate color spray paint.

width of the sheet metal is usually about one meter, and the length can be ordered as a standard - 6 meters, and cut along the length of the ramp.This greatly simplifies the installation and reduces the time for adjustment sheets.In addition, at the order of sheets in the size of the slice metallocherepitsyokazyvaetsya covered with a protective film, which increases its service life.Stack metal roofing on a wooden crate and fastened by means of special self-tapping screws in the tone of coverage.Screws have a sealing washer to ensure integrity of the roof.When roofing metal roofing complex shapes can be cut using scissors or jigsaw for metal.Use for this purpose grinders can not - in the place of the cut polymer coating burns, and soon begins to leaf rust.

The advantages of metal roofing include:

• High resistance to snow and wind load, which allows its use on roofs with virtually any angle of slope;
• Durability - lifetime quality metal is from 25 to 50 years;
• Smart appearance and bright colors, do not fade in the sun, wide range of colors;
• Corrosion resistance while maintaining coverage;
• High fire properties - metal does not burn and can withstand open fire load for 1 minute without risk of damage to wooden structures and crates;
• Metal does not change its properties at any temperature;
• smooth surface is easy to clean from snow.

metal Disadvantages:

• high degree of sound transmission: the noise of falling drops in the rain will be clearly audible in the attic;
• tendency to the formation of condensation and ice from insufficient insulation of the roof;
• Installation of metal complex on the shape of the roof is quite complicated and requires accuracy, as well as the use of a large number of additional elements, strips of contiguity;
• Deep scratches, as well as the great damage of the polymer coating can cause the appearance of corrosion.They need time to paint special paint from a container.The paint can be purchased from the manufacturer of metal.

Features Ondulin Ondulin

- profiled roofing material of cardboard impregnated with bitumen under high pressure with the addition of dyes, plasticizers and reinforcing fibers.The result is a wave-like sheets, shaped like slate and having high hydroprotective properties, plastic, easy to assemble.Onduline has several colors, shades - soft and muted, reflecting the light.

Krepjat ondulin to a wooden crate with special nails with sealing head into the upper wave.With its low weight Ondulina crate can be carried out in increments of 50 cm. If necessary ondulin easily cut with an ordinary hacksaw, and its flexibility makes it easy to mount it on the roof of the complex form.In the cold ondulin becomes brittle, its mechanical strength is reduced, so it is not used for roofs with a small angle of slope of the possible large accumulations of snow.

Ondulina Advantages:

• strong and durable material, the warranty period - 15 years lifetime with proper installation and operation - 25 years;
• velvety surface and soft shades allow to make the roof of Ondulin attractive appearance;
• material resistant to mikroorganizvom, has good waterproofing properties even in small areas of damage due to the bitumen impregnation;
• Onduline is absolutely harmless unlike slate containing asbestos;
• Onduline has high noise-attenuating properties perfectly dampens noise drops, so it is often chosen for the roofing of houses with an attic floor housing;
• no condensation.

ondulin This has disadvantages:

• Bitumen, which is part of Ondulin, flammable, so the material does not have the fire properties;
• In the cold ondulin becomes brittle, the heat softens, making it impossible for its installation and maintenance in cold and hot weather;
• ondulin the sun fades with time, loses brightness;
• velvety surface detains snow, dust, debris from trees, so the roof from time to time need to be cleaned, otherwise grow on the surface of the moss and lichens.

Choosing roofing

After reviewing the features of these materials, we can conclude:

1. not recommended for roofs with a slope angle of 15 degrees in regions with lots of snow ondulin.Such a roof is better to cover a metal tile.
2. roofs of buildings with attic floor, it is best to cover the Onduline, metal roof of the rain you will hear the sound of drops.
3. When using heating furnace roof of metal provide better fire protection properties.
4. On roofs without insulation at a low temperature on the bottom side of the metal will produce condensation, frost, and in the spring when melting water flows into the attic.In this case it is better to choose ondulin, it does not have this drawback.
5. Installation metallocherepitsyna roof complex shape requires skill and availability of jigsaw.Ondulin in this case can easily be cut with a hacksaw and slightly bent.

In all other cases, these materials provide equally good protection from the rain and wind, so their choice is determined only your personal preferences.When you purchase any of these roofs need to ensure their quality and authenticity in order to avoid counterfeiting.
