I used a 2x6 as the ridge board (looking back, I have no idea why). The 2x10's hang below the board about 4 inches. The 2x6 portion of the roofs hangs below the ridge about 2 inches. I did not specify a ridge size in my submitted plans. My question is will this be a problem. If so, can I slide a second 2x6 between the rafters to compensate?
2. The rafters of the shed dormer are offset from the original rafters. I framed the dormer wall at 16" centers. However, I neglected to line the wall studs up with the existing 2x6 rafters on the other side. As a result, once the wall was lifted the wall studes did not line up with the existing rafters. I chose to put the dormer rafters over the wall studs and offset them from the original 2x6 rafters, rather than line the rafters up and have them offset from the wall studs.
Just wanted to get an opinion on these two issues. A couple of additional facts- There are 2x6 collar ties at 16" centers and a height of 8'. Since the rafters didn't line up, I installed a nailing board the length of the existing roof and cut that end of the collar ties at an 8 pitch. The roof is a standing seam metal roof. I built this just before the winter and had about 3 inches of pure ice on the roof and have had no problems.
Adam,
Without pics, it is difficult to fully grasp the conditions. In addition, it is difficult to read the mind of an unknown inspector. The reality is that we all see stuff that passed inspection that should not have.
Putting in an additional 2x6 below might satisfy the building inspector or it might not. In my neck of the woods, the building inspector would want a letter from an engineer saying it was OK.
The rafters should have lined up with each other. Once again, I see lots of rafters that do not line up and are passed. Once again, there is often a difference between what passes inspection and what is right.
For some reason, I am completely unable to visualize the conditions in your last paragraph.
