The reason is that the truss is the most important part of a roof structure, and because of this, it has to be designed and constructed in a particular way in order to ensure that the whole is strong and sturdy enough to carry the weight of the entire roof. Think about it – if a truss were not constructed correctly, it could break at any time, which would be very catastrophic indeed. It’s just a fact of physics that you simply cannot have a weak truss system on the top of your house. This is also why Oak Roof Trusses are chosen over many other types of wood as they provide the strongest support.
So what makes a good truss system anyway? The most important factor of course is that the trusses are the ones that hold the entire roof together, and this is why they need to be perfect in every single way. The strength of the trusses, their angles, their length, their width – all of these must be considered and implemented when manufacturing a proper roof, and the best way to ensure that the trusses are as strong and sturdy as they can be is to build them at the factory and have them sent to the construction site, where they’re bolted to the sections of the roof. This also ensures that everything is perfectly square and in line as well.
This is the reason why the truss is such an important part of a house. Without the trusses, the entire roof would simply be a pile of unsightly, but useless shingles,on the point of collapse. So even if you think that they’re not important at all, you should still invest in them, and they’re definitely the best way to go.
