Can a trussed roof be vaulted?
To convert a truss roof to a vaulted ceiling, you may need to do significant reconstruction of the roof. If the roof was built with traditional rafter-and-joist construction, the ceiling joists work to resist the lateral force of the rafters pushing outward on the walls.
How do you calculate trusses?
Truss count = ((roof length * 12) / 24) + 1 The simplest form of this equation is to take the length of your roof and divide it by 2. For example, if your roof is 40-feet long, it will need a total of 20 trusses.
What is the difference between queen post and king post?
A queen post is a tension member in a truss that can span longer openings than a king post truss. A king post uses one central supporting post, whereas the queen post truss uses two. Even though it is a tension member, rather than a compression member, they are commonly still called a post.
What is a queen post roof truss?
Queen Post Roof Trusses are very similar in design to king post trusses except that the interior of the truss has two vertical ‘queen posts’ instead of one central ‘king post’. They look great and offer an open area in the middle of the truss. Queen post timber trusses can easily span 30 feet or more.
What should I look for in a truss calculator?

Because king post trusses are made with few materials and a simple design, they come at a lower price point than many other trusses.
