Now that we have completed the valley set-up inside, and and have installed all necessary bearing points outside, we could now start putting the two systems together. The process starts by flying in the three common valleys and placing them in space so that we could scribe and cut them into their final positions. The precision and meticulousness required to ensure that, once the valleys were installed, that all of our roof planes transitioned correctly from the common rafters to the jack rafters was off the chart difficult. We are talking about setting 3 9x12x22′ valley rafters with a precision of 1/16″ of an inch, in 3 different planes and they all have to relate with each other and the existing frame correctly. It is hard to even describe what needs to happen, not to mention actually accomplishing it.
