Metals have been used in its various alloys as a material for roofing, and this practice has been in vogue for centuries. The tendency of metals to form rust did create a lot of problems for maintenance, which negated any advantages of their high strength and durability. This rust formation required roofs to be painted periodically, sometimes almost every year, in order to continue to get the advantage of these roofs.
This problem of maintenance was solved by developing technology that allowed permanent paint to be applied to galvanized steel to give the very versatile colorbond roofing. This process is a mechanical one and ensures that the applied paint stays on even in the worst of weather conditions. As the basic material is galvanized steel, the creation of shapes in this roofing allows colorbond roofs to have very high strengths and an ability to span large distances, while still maintaining a very low weight.
Colorbond roofs require almost no maintenance and this can be a huge saving in recurring costs, besides saving the problem and inconvenience of getting any repainting done. The material can be used for any shape of building and is not restricted to use in commercial buildings, with even homes opting for this solution. Colorbond roofing can even be welded so that there is no worry about joints, which can lead to leakages, or to create cover for large spans. The metal content of the roofing ensures that there is rarely any moisture related damage to roofs. The lightness of the basic material allows for easy installation and huge areas can be covered in a single day. Costs are comparable to the options of wood or tiles. It is also very easy to repair or replace the roofing when any particular panel is damaged.
Colorbond roofing has high insulation values and this can lead to lower costs in any insulation needed to be done to conserve energy. The large range of shapes, grades and colors are an architect’s delight and can give any property where this roofing is used, a fresh look. The surfaces have a high reflective nature and this can keep a home cooler when temperatures are high in summer. There is no special expertise required to install this form of roofing and this does lead to low construction costs. Roofs with this material have a life of about fifty years compared to the 20 years that an ordinary galvanized roof would have.
The low weight of this roofing material allows engineers to save costs on supporting members, and where compared to concrete tiles the weight is only a fraction. The roofs are rodent proof and you will rarely hear of rats getting through this metal roofing. Water runs off easily making it ideal for any rain water harvesting, though the noise of rain on this roofing can be irritating to some people. This type of corrugated roofing has become very popular for homes and commercial buildings because of the attractive appearance and the elegance that it lends to buildings.
If there are any issues in your roof regarding asbestos, you should check with your roofing contractor and see if you need to undertake the proper worksafe procedures to remove asbestos. If not done properly it can be a health risk to anyone in the vicinity as asbestos dust spores, when moved, can lead to very serious illness if breathed into the lungs.
