Description

As roofs of other materials, these roofs are used to cope with the house or building.

The advantages of metal roof over concrete roofs and other roofing materials are very light, weighing only 1/10 of the concrete roof. This metal roof is suitable for use in earthquake prone areas or those with peat soils

Metal roof

The market share of metal roofs has purchasing power of about 20%. The bestsellers in roof construction are galvanized steel sheet roofing materials profiled with polymer layers, colloquially called trapezium sheets or corrugated boards. In recent years, stable demand among consumers in Indonesia is also using metal roof tiles. The volume of the metal market in the country is about 50 M ?. Like a sheet metal roof that mimics traditional ceramic tiles, has an attractive appearance and a relatively affordable price.

By complying with all necessary requirements of metal roofs can last up to 20-30 years. The durability of a metal roof depends on the quality of the metal being produced. But not all manufacturers have maintained the right production technology. This leads to the fact that during long-term use may worsen. From installation requires a very high level of professionalism, which, unfortunately, is not always followed. In all European countries the minimum thickness of metal sheets allowed for residential roof use shall be not less than 0.5 mm. In different climatic conditions, given the rainfall and other atmospheric factors, therefore, emphasized on the roof with a thickness of - 0.7 mm or more. However, in our country, some vendors offer a thickness of 0.4 mm material, which can be used only in small buildings, canopies and awnings.

The main drawback is the vulnerability of metal roofs to corrosion, which becomes a disruption of the protective layer. And it is easily damaged both during transportation and during installation (when cutting sheets in binding process, etc). The most common cause of injury from the roof is a mechanical action on it at the time of installation or repair from the roof. These factors can result in scratches, holes, clips slipping. The hole formed finally pierced the humidity, which became a temperature disorder in the roof. Everything of this type of sheet metal roof can end in corrosion. Due to the sheer thickness of the sheets, within a year may allow it to become damaged.

Any metal after a while starts to rust. Painting on the roof, can extend the material keslangungan. In addition, ordinary painting is required not only on conventional steel roofs, but also zinc-coated metal. But that means that it must be continuously periodically given the treatment involved in the roof repairs as well as to restore proper appearance. It's a fact, apart from the hassle and inconvenience, it will also require additional fees. Not to mention a few decades later sheet metal and roof there is a desire to be changed completely.

Having a metal roof will still face some other problems in its use. For example, metals can conduct and accumulate static electricity, and the combination of zinc in relation to some form of galvanized steel, in which the effect of galvanic corrosion develops. In addition, metals heat up quickly by sunlight and are very noisy in case of rain. And when metal roofs do not have good acoustic isolation properties, this kind of home atmosphere is not fun. While the other side of the sheet metal is also still not very well safe, it is "rumble" from the gust of high winds, which also does not add to the comfort of home.
