When people talk about the roof of a house, they usually refer to the material covering the home such as asphalt, metal or stone. However, a roof can also refer to the framing structure that supports the roofing materials. This is an essential building block without which roofs would be impossible.
Many different materials are used to construct roof frames in other parts of the world, but Essex County roofers use wood frames with wood or plywood sheathing as do many other roofers across the United States. Wooden frames are stronger and can support greater weight than plywood can, but plywood can be made much more cheaply. Trusses, on the other hand, are always made out of solid wood, and plywood is never used.
The difficulty in framing a roof fluctuates greatly with the design of the roof and according to whether the frame will incorporate a truss or not. The presence or absence of a truss system not only affects the overall design of the house but also changes the complexity of the frame. While all frames employ battens, joists or rafters, and other structural components, their application within the framework will be modified if a truss is utilized.

Many roofers use trusses to augment traditional framing methods because it simplifies the work and reduces the amount of time used in construction. Traditional framing is a complicated process that requires expert skill and a strong knowledge of engineering and design. Trusses require a similar amount of engineering but are built in a factory and arrive on site already assembled, which reduces the construction time.
Although there are certain advantages in employing a truss, they do not necessarily suit every purpose. Due to design requirements, the support beams used in a truss often take up a great deal of space, which can make attics less effective for storage and nearly impossible to inhabit. It can also be difficult to fit a truss inside complicated roof patterns. Some high end homes feature complicated roof designs with many valleys, different slopes, a variety of peaks, dormers and penetrations. It is difficult to fit a truss inside houses like these.
Once a truss has been set in place, it is not possible to modify the truss at a later date; trusses are static. If the homeowner decides to install a tile roof on their home and the roof is not capable of supporting the weight, the frame will have to be modified to support the additional weight. When building a home, it is better in the long run to have a sturdy frame built, even if a truss is planned. The extra support can be a valuable investment.
