"Is this design good for structure? Carpenter told me he did a couple of neighbors in the past year this way and it worked well." ----- Whoa, slow down.
Start with the basics: http://books.google.com/books?id=E5S...raming&f=false
Ceiling joists are required, OR rafter ties – every 4’ apart
on a non-structural ridge roof system. This is per MINIMUM building safety code. (IRC 802.3.1) Google it….
If the pitch is low, the rafters need to be engineered, per code again. (IRC 802.3)
You really need to run this by your local Building Department, not the local carpenter, at least for the liability for insurance purposes…
Be safe, Gary

They leave a residue that impedes air-flow, costing you money.
Clean the ducting in the last six months? 17,000 dryer fires annually!
