There are also three things that will affect roof truss spacing:
There will be a lot of different pressures that act upon this different times over the course of the life of the roof, and so you need to have trusses that will support your roof through thick and thin.
For instance, aluminum is a very light material for you to build a roof with, it is commonly used in mobile homes and caravans this means that you be able to get away with more space between your trusses.Īlternatively, you could have something different entirely, such as a thatched roof or other material which is organic material. If you are using metal, depending on what the metal is, this can be either heavy or very light. This is going to be very heavy, and so you do need the trusses to be closer together and capable of supporting more weight. If you are holding according to regulations in which you have to build an old-fashioned style for instance, you might need to use a heavy slate or other stone-based materials. Also because the material that you use to build the roof will it affect how thick the material for the roof truss’s needs to be, and it will also affect how many of them you need within a certain space. The material that is used to make the roofing. Obviously, a wider building will require more trusses than a very narrow building. You need to know the width of the building, because the width of the building will determine the surface area of your roof.
