Trusses, for anyone who is not familair with house construction or unique commercial construction, are the framework of many roofs. (Many commercial buildings typically have flat roofs, so trusses are not used in commercial construction all that often.) Trusses are designed and built by manfacturers, but the people that actually design them are quite important, and here is why.
Architects play a part in designing trusses because they are the ones that design the houses and buildings that use trusses. An architect cannot place a gable or dormer window anywhere in his or her plans without having a truss or two built around it. Additionally, architects have to know exactly which type of truss creates what type of roof feature, and if existing trusses do not work, then the architect designs one.
Structural engineers also design trusses. It makes sense, given that structural engineers have to calculate for the expected loads that roofs need to bear all year long. It also makes sense that structural engineers are responsible for designing custom trusses, because the more unusual the roof, the more demanding the load-bearing needs and structural integrity needs of the roof.
Why It Matters (Who Designs Trusses and Who Does Not)
Architects and structural engineers know exactly what they are doing. They have been trained to design, plan and construct buidings and houses that are safe, comfortable and attractive. They know exactly what it takes to create unique roofs and unique structures and how to modify the current available truss options for each individual roof. You would not take your home design or roof design to a doctor and ask him to create trusses to fit your designs, or take your home ideas to anyone else not equally qualified for the task. Even if you asked most construction contractors if they could recreate a specific roof from pictures you give them or from your own drawings, they could not do it and would refer you to an architect and/or a structural engineer to accomplish the task.
In addition to all of this, unique trusses and their designs have to be inspected by safety inspector to make sure they will not fail or cause the roof to falter. A safety inspector may request the spec sheets from an architect or structural engineer to prove that the computations for load-bearing and structural safety have been made and made accurately. Most of these computations and designs are created with the help of a CAD-assisted computer and software, which only architects and engineers typically know how to use and operate.

Welcome to my website. I'm Albert Frost. Besides my dad, one of my biggest role models was my uncle Rick. He was a construction contractor who would let me come on his construction sites and also taught me everything he knew about building homes, including how to install hardwood flooring and add insulation. I always wanted to grow up to build houses like my uncle. I used to help my uncle with a lot of the grunt work needed to make a home a reality. But then I hurt my back playing football. Until I heal completely, I'm going to devote as much of my time as possible to teaching others about various construction topics I'm interested in.
