The pros of using roof trusses drastically outweigh the cons. There might be a few instances where you need to go with stick framing as this is what the build requires, however, most of the time a truss is going to be much more beneficial.
Roof trusses are specially engineered. All trusses have an engineer seal on them, meaning that they are made to universal standards.
Trusses are built and constructed in a controlled environment, well out of the way of any variable factors such as the elements – rain, wind and snow –which means you don’t need to wait for the ideal weather conditions in order to be putting it together, you are in control of the production schedule.
Trusses span much larger distances without having to be supported. This allows for much more flexibility and space.
Trusses are made with computer programmed saws, meaning a greater accuracy, a machine focused fits, without the potential for human error and much more lumber efficiency – saving the planet to boot!
This means that we waste barely any timber every single build. Doing this with stick framing or rafters to the same degree is nigh on impossible.
Trusses are built on the ground inside a workshop and then placed onto existing walls. This removes the chances for any accidents to occur which means a safer and more secure build project.
Rafters are used less and less all the time, mainly due to the much higher cost of rafters when compared with trusses, however, they do have a few distinct advantages. Stick framing (rafters) is flexible and can be altered fairly simply without compromising the structure. As a result, you can create an open space under the roof, so you can expose the entirety of the space – this is enjoyed by the likes of vaulted or cathedral ceilings. It’s also possible to build an additional room such as an extra bedroom, a home office or a storage space, it is also simpler to accommodate a home addition with rafter roofing.
Though actual installation is slower than it is for trusses it requires less lead time in order to prepare so if for some reason you are in a hurry, rafters are quiver overall, they are also appropriate for more remote environments while transporting a pre-assembled fabricated truss might be logistically difficult. Another situation is a smaller construction, where a site-specific truss design might not be too cost-effective.
