Putting Up Roof Trusses

Putting up the roof trusses feels like a major milestone, as for the first time, the house finally has it’s basic shape established. As of the publishing of this post, we have about 3/5ths of the trusses in place. Having figured out the rhythm of the process, the trusses go up at a good pace.


To begin this stage of construction we put up support posts on the exterior of the east and west walls for the gable end trusses. We got these support posts nice and plumb and sturdy. We then put up the two drop gable end trusses at each end of the house. This allowed us to tie string lines from end to end to make sure all our trusses would be square and level with each other. We ended up using three string lines: one at the peak and one at each overhang.

We then started adding trusses from the west end of the house. The truss adjacent to the gable end connected to the gable end with freeze blocks where the trusses sit on the walls, a freeze block between the bottom chords of the trusses, and a freeze block just below the peak of the trusses. We also set our outlookers, which are 2x4s that butt up against the second truss, span over the drop gable end truss, and extend out past the end of the house to allow for an overhang.

After these two trusses were up, the subsequent trusses were simpler. We would make sure that each truss was lined up in the center and along each wall, and sometimes we’d need to do some shimming to get things a little more level. Daniel would hold the truss as I nailed our blocking in. Once the four freeze blocks were nailed in, I’d check the spacing between the trusses at various locations. We’d typically need 1-2 additional blocks on each side of the truss to help maintain a consistent 22.5 inches spacing between the trusses. DSC_4284.JPG
