A roofer, roofing contractor, or roofing mechanic is someone who usually specializes in roof repair. Roofers repair, replace, and install the roofs of commercial buildings, using various materials, such as asphalt, shingles, metal, and bitumen. Roofing work can also be physically demanding since it involves climbing, bending, and twisting, most of the time in inclement weather conditions. Because of these conditions, roofing contractors also have highly specialized equipment and skills that are required to make their job easier and safer.
Roofing refers to the fixing of roofs, which involves placing metal sheets or tiles on top of roofs to strengthen them and to waterproof them. Roofing materials come in different types, such as aluminum, wood, slate, stone, clay, glass, metal, fiberglass, ceramic tiles, metal roofing, ceramic tile, gypsum, and zinc. The roofing system used mainly depends on where the building is located, the climatic conditions prevailing at the site, and the preferences of the owners. Usually, a roofing system comprises of roofing materials like asphalt, cellulose-cement, dry fiberglass, metal, laminate, and flashings.
There are several types of roofing works such as repair, installation, and maintenance. Repair involves replacements of damaged or missing tiles; cleaning; and cleaning the roof after damage has occurred. Installation, on the other hand, involves fixing a new roof on the existing structure. Roofing repairs and installations can be carried out by a single individual or by an entire team, depending upon the complexity of the project and the safety requirements for the work. However, many roofers prefer to carry out roofing work by themselves to save money, while ensuring the quality of work.
There are three types of roofing materials on which roofing work is carried out: shingles (a type of roofing material that consists of paper-thin sheets of metal), slate, tile, and fiberglass. All the three materials provide varying levels of insulation. They also serve to protect people and property from various weather phenomena. Different roofing methods include the use of nails, screws, metal clips, Velcro, and other fasteners.
There are two types of roofing systems: cedar shake and asphalt shingles. The most common roofing material on which most of the residential projects are carried out is asphalt shingles. These are made of paper-thin sheets of metal. The asphalt shingles are extremely fire resistant, but they are very soft in nature and hence crack easily. Asphalt shingles are also vulnerable to puncture.
Thus a new layer of shingles or a cedar shake roof is required for older homes. A different kind of roofing is needed for the roofs that are subjected to heavy rains. In such a case, a water-resistant layer of cellulose is used on the underlying structure. The cellulose is kept in place by pressure or weight.
