Over the last 50 years, roofing equipment has grown tremendously. During a particular period, every roofing operation, from lifting gravel to felts to spreading, and fastening sheets were done by hand. Roofers exerted energy and wasted time in doing this. Presently, machines have made many procedures easy. Nevertheless, a roofer must understand their way of operation and care in order to build a roof safely and successfully.
Notable examples of machines that have helped in making built-up roofs faster and easier include gravel spreaders and Felt layers. Nowadays, there are machines for applying gravel and flood coat in one operation. Regardless of the fact that this procedure is ideal for large jobs, the hand is still used a large number of small jobs. Hand operation is still required in large operations in areas like, flashings, parapet walls, and application around skylights. The skills of a professional roofer cannot be substituted by machine however; proper usage of the machine would ease the performance of the job.
Felt Layers: there are two types of felt layers used, they include the dry layer which requires someone to mop in front of it, as well as the combination layer, which spreads asphalt unto the deck while it lays the felt. There are many variations in the combination felt. In some cases, the asphalt is applied 3y means of gates or valves, in others like the rotary felt layer (a stationary unit), a drum is used to apply the asphalt is applied directly to the felt. Some are only ideal for working on nearly level or level roofs while others can be latched to slope through the help of adjustable legs. Nevertheless, the practical use of an automatic felt layer is dependent on the greatness of the scope.
