During the complete replacement of a roofing system or the construction of a new home, roofing contractors have the options of manually assembling traditional roof frames or using prefabricated structures called roof trusses to support the roof. Bergen County roofing specialists generally favor the engineered roof truss for the convenience of use and cost savings it provides.
Roof trusses, which can be built of wood or steel, can be divided into two primary categories. The flat truss, or parallel chord, has top and bottom beams that run parallel to one another; this truss is often used for flat roofs and the construction of flooring. The common or pitched truss is triangular and is the more popular truss for roof construction. Both of these types have many variations that roofers can choose from to fit a roof of a certain size, design or shape. Each variation also has its own advantages and disadvantages.
When trusses are ordered, roofing contractors have to specify the length of the bottom beam, number of trusses, roof slope, type of truss and other measurements to ensure that the right structure is being used.

To construct the roof, the trusses are usually situated at regular intervals along the frame of a house and are connected by pieces of lumber called purlins. Roof sheathing is added on to form the roof deck, followed by underlayments and the roof covering of choice.
There are a number of reasons a roof truss is the ideal choice for roofing contractors. In terms of labor, using trusses is cheaper and faster than building a roof frame. It generally takes only day to install trusses, which can speed up the roof building process; they are often transported to an installation site and installed with the use of a crane. Roof trusses are also built to adhere to building codes and to fit any standard or custom roof design while using high quality materials.
Homeowners may be hesitant use roof trusses made of wood as they are susceptible to fire. This risk can be avoided with the use of steel roof trusses, but they are usually more expensive. However, many will find that the main disadvantage of using a roof truss is that its web framing may leave homeowners with little or no usable attic space.
When planning a new roof construction or replacement, homeowners may want to consider the practicality of using roof trusses. They can consult with their roofing contractor before making a final decision.
