Roofing is one of the important aspects of any home or commercial building. A roof is actually the covering of a structure, which includes all structures and materials needed to support it on top of walls, on uprights, or wherever else on the structure, giving protection from the weather, rain, sunshine, extreme temperatures, and winds. The roof also allows air to flow over the structure, as well as providing insulation for heating purposes. Roofing is actually a part of the total building envelope.
Are You Embarrassed By Your Roofing Skills? Here’s What To Do
There are two kinds of roofing materials, which can be used to provide roof protection from elements. One is the thatch roofing, which must be replaced periodically because it can damage your home’s structure and weaken its foundation. The thatch roofing is made of straw, twigs, and leaves that are mixed with mortar and poured onto the roof. If the roofing is made of metal, the roof may be coated with a layer of zinc to prevent corrosion, but this coating must be removed every few years to allow for the growth of pests.
When you hire roofing contractors, check their credentials. Find out if they belong to a roofing trade association or another organization that certifies them. You should also ask if the roofing contractor is a licensed roofer, which means he has completed all of his training and passed the National Roofer Inspection. It is also important to find out what kind of insurance the roofing contractor has because fire damage can be very costly to repair. Lastly, find out how soon the roofers will arrive to inspect the work and whether they will do the installation themselves or hire other contractors to do the job.
