Because so many commercial buildings use metal roofing, commercial roofing contractors usually need to be experts in metal roofing. Metal roofs require special knowledge and experience, so contractors need to be aware of this in order to install and repair them properly, whether for commercial buildings or residential properties. When installed correctly, metal roofs can last for up to fifty years before needing replacing, making them very good value when compared with other materials on the market.
Properties of Metal
Metal roofing contractors need to be aware of the unique qualities of metal roofing materials. Metal favoured by contractors because it is very lightweight, requiring a less heavy framework in the building, and is easier to manipulate and handle. Metal is durable and easy to fit together, especially when compared with materials like tile or slate. Contractors need to know how to join metal roofs together, however, as metal can expand and contract more than other materials. This requires certain techniques in order to install it correctly.
Because the range of metal roof styles has expanded so much in recent years, contractors need to be aware of all the options available. The man style of metal roof used to be the seam metal roof, which is made of squares of metal placed alongside one another and joined by hidden fastenings. The end result looks like one large piece solid ridged metal. Nowadays, metal roofs can be made to look like many other types of roof, such as cedar shakes, slate, or tile. Because there are many different styles, a contractor has to know the different ways of laying each style.
Finding the best contractor available takes some time and effort as there are some important questions you need to ask. Ask whether or not the contractor is licensed by the relevant local authority, and whether they are bonded by a surety company. It is also very important that the contractor is able to provide proof of insurance showing that both the contractor and any workmen used are covered for the entire length of the project. The insurance policy should also provide worker compensation for any worker who is injured on a job. This will protect you from liability should anyone be injured during the work. A good way to check out a potential contractor is to ask for a list of references from previous clients so you can see for yourself the level of previous work.
