Thanks for your responses! Yes, I've been looking for a Structural Engineer to work on the plans but since many people in my neighborhood have added on, we had an idea of what we were getting into. We already have bids for all the piering. I have a contractor looking at the plans this weekend but it would be nice to at least give him the correct idea on the front of the house for the roof. I have consulted with a couple of architects since I'm a designer to make sure it was in good shape. So I'm mostly at this point dealing with not really understanding roofs.
I'll check out the links in this thread.
