Measurements are one of the most important pieces in the design work that we do. Ultimately, it is up to you and/or your general contractor to confirm them.
While we do complete the truss, floor, metal, and beam designs, we base these off of the information and dimensions supplied by our customers. The dimensions that we will need to confirm prior to production include:
The truss span is the most important of measurements in your project. Simply put, this is the width you would like your building to be. This can also be taken as a dimension measuring from Butt Cut to Butt Cut, along the Bottom Chord. This can also be measured from one outside wall to another.
The building length is the second most important of measurements in your project. The length tells us exactly how many trusses you need. When telling us the length, please also keep in mind if you would like all common trusses or gable ends. We will also need to know how you would like your trusses spaced. The most common is 2′ on center, or 4′ on center dependent on the building size.
Roof Pitch is the next most important of measurements in your project. This will determine the overall height of your trusses, and your roof. It’s often thought that only certain pitches will work for certain locations, but that’s not the case! We are able to design your trusses as you’d like, and will ensure it is up to code for the snow, wind and rain load for your area.
A roof pitch is determined by the RISE / RUN. For example, a 4″ rise for every 12″ run would turn out to be a 4/12 pitch. Common pitches range from 3/12 to 5/12. If you would like to have a more flat roof, 0.5/12 to 2/12 is common. If you would like a higher pitch roof, you can use a 10/12 or higher!
Your overhang measurements are taken from the end of the Bottom Chord to the end of the tail, not including the fascia. If you have a wall that is cantilevered, the measurement will be from the outside of the wall to the end of the tail. your overhang provides just that, overhang from the span of your truss to allow for extra protection and coverage from snow, rain, or hail.
The heel height measurements can be thought of as the ‘thickness’ of a truss at the end of a bottom chord. You may add extra heel, giving extra height to allow for more insulation in your build. You may also reduce the amount of heel in the case that your building will not be insulated at all. A standard residential heel height can ranger from 4-5″. A raised, more energy efficient one can be up to 12″.
