Before undertaking a roofing project, you should first be aware of the many options available in the market. While almost all roofing materials have no problem in keeping the rain out, you should go for roofing materials that are more durable, lightweight and those that guarantee the answers to the customers’ need for a fire resistance roofing material. No material offers these qualities more than a metal roofing material.
Types of roofing materials
1. Aluminium roofing
Among the metals used for making roofing, aluminium is arguably the lightest and also naturally rust and corrosion resistance. Due to its formability, aluminium roofs offer greater overall design versatility. The rust –proof properties of aluminium makes it’s a better choice in coastal regions since the salty and moist conditions at the coast are known accelerates rusting.
The downside of using aluminium is that it is not aesthetically pleasing and therefore mostly used for practical purposes only. The fact that aluminium is a soft makes it prone to damage from falling hard objects. Aluminium is also relatively expensive compared to other metals.
2. Steel roofing
Steel is the strongest and the heaviest of the metal roofing materials. It’s an alloy metal made by combining iron and other elements. Initially a popular material in commercial construction sites, steel is now gaining popularity in residential buildings. Steel is available in a wide variety of finishes from galvanized steel to weathering steel to galvalume steel. The main advantage of steel is its flexibility of use and low cost and the fact that it’s more available when compared to other metals. The problem with steel is that when left uncoated, its most likely to corrode more due to moisture and galvanic processes when compared to other metals. Its weight also puts quite some stress on the structure of its property.
3. Copper roofing
Copper metal, just like aluminium, will not rust however it eventually develops the verdigrises’ patina common with roofs of old buildings when left untreated for a long time. All in all, copper metal is extremely long lasting and easily recyclable thus making it an ideal roofing metal. Copper is a soft metal therefore relatively quiet when sleet or rain is falling down it. Again, copper is aesthetically pleasing therefore well preferred for decorative style purposes. The drawback of using copper is that it’s very expensive and its soft nature makes it susceptible to hail.
4. Zinc roofing
Zinc may not be as popular as steel but it’s one of the common elements found in nature. It requires much less energy to fabricate when compared to aluminium and steel therefore considered eco-friendly. Zinc is 100% recyclable and usually preferred for commercial projects since it can easily be moulded into desired shapes. Untreated zinc is extremely durable and highly corrosive-proof, lasting over 100 years and relatively quiet when coming into contact with rain. The downside to zinc is that it loses its aesthetic as time goes by. Again zinc is relative soft and easily damaged by hail.
5. Tin roofing
Unlike other metals discussed above, tin is an extremely rare metal and less popular for roofing. Tin roofs are mostly not commercially produced but rather reused by local DIYers. These locals usually flatten containers and tins made from tin metal to make their roofs. Its highly resistance to corrosion although the material covering it can wear off over time.
Tin is available in thin sheets thus making it lightweight and therefore easy to handle. Despite tin being cheap it’s known to be notoriously noisy when being rained on.
