A metal roof also known as a tin roof or it is a roofing system made from metal pieces. It is one of the important parts in the construction of a building. Metal roofs deteriorate if they are not properly protected. Metal deterioration can be due to rust and corrosion, abrasion, wear, and chemical agents etc. In order to protect the metal deterioration from these agents the only solution is metal coatings. Metal coatings protect roofs that are made of any materials that deteriorate easily.
These metal roof coatings restore and extend the life-span of aging metal roofs. Metal coatings are applied to roofs in the form of lubricants, or as torque agents. Metal roofs enhance the look of the building as well as they last many years.
There are many different types of metal roof coatings available. Following are some of the common metal roof types.
Corrugated galvanized steel: this is a combination of wrought iron–steel sheet coated with zinc and then roll formed into corrugated sheets. This is widely used in many areas.
A combination of zinc, aluminum and silicon-coated steel, sold under various trade centers in the names of “Calumet”, “galvalume”, etc.
Metal tile sheets are usually painted or stone-coated steel.
Stainless steel are is considered as a distinctive design element.
Aluminum is expensive when compared to steel because it is one of the longest-lasting metals. These are very light weight, dust-resistant, reflectivity properties, and have good emission properties etc.
Copper metal roofs are very expensive and only used for flashing or highlighting some areas. It has variety of potential uses.
Stone coated steel roofs are made with a colored ceramic coating.
Inverted box rib (IBR) made of corrugated square fluted iron roofing material. It is cheaper.
