It’s no secret among homebuilders and contractors that roof framing has rapidly evolved over the past few decades. Traditionally, they relied heavily upon conventional rafters and ceiling joists for roof construction, but trusses have gradually become more prominent, with upwards of 80 percent of all new construction now utilizing trusses as the primary means of roof framing and support. So what are the advantages of using this particular roofing system? Below are some of the key benefits of building with roof trusses.
- Reduced Expense
Conventional rafters have to be cut, custom built and installed on-site, which can really pack a punch in terms of expense and labor costs. Trusses, on the other hand, are manufactured off-site and ready to be installed when they arrive at the construction site, which can significantly reduce expenses.
By virtue of their web-like design, trusses make use of smaller pieces of wood (which are less expensive) that are linked together by tooth plate connectors. Because of this unique and highly versatile design, trusses offer exceptional strength and can span large distances, making it possible for builders to rely less upon interior load-bearing walls. This can allow for a more open floor plan while reducing costs at the same time.
In addition, because roof trusses are comprised of engineered wood in an indoor facility, they aren’t exposed to moisture and other weather conditions, which means a higher quality product overall for the price.
- Faster Installation
As mentioned, trusses offer a quicker installation than conventional rafters, which have to be built on-site. Roof trusses are pre-fabricated in an off-site factory using automated tools such as computer-aided saws. The truss system is then delivered to the construction site and installed with a crane, oftentimes within only one day.
This speeds up the overall construction process and closes up the structure quicker, which means that the interior of the home will receive less exposure to various weather elements during the building process. Although roof truss systems offer an advantage over rafters in terms of reduced installation time, it should be noted that the lead time for preparing rafters is shorter.
- Flexibility of Design
As home building technology continues to evolve, builders and contractors are working with a much more complex range of roof designs. This complexity lends itself to roof truss systems, since they can be configured to accommodate practically any roof shape and design you can think of.
The addition of various features such as unique angles, cross gables, cathedral ceilings, etc., can increase costs, which many times would be prohibitively expensive if a traditional rafter system were to be used, but roof trusses allow for a more economical construction of complex roof systems. Builders can also benefit from the fact that trussed roof systems are professionally engineered, which means that the finer details of the roof’s design are often constructed with a greater level of precision.
Most builders and contractors today will tell you that engineered roof truss systems are the best way to go, for many of the reasons cited above. If you’re looking for optimal construction speed and efficiency along with a greater level of cost-effectiveness, choosing to build with roof trusses is the best option on the table.
