I am contemplating removing my old stick build roof, and replacing it with
an attic truss. Does anyone have any good weblinks, or personal experience
with this type of project??

Any particular reason to do this?

The existing roof is deflecting under snowload, there is no attic space, and
I wish to have proper eave ventilation.

Jason:

I recommend that you block up on top of the exterior walls between the
ceiling joists to get a flush surface. Then add a 2x flat above the top
of the joists, to give you a new sill plate. Set your new trusses on
top of this plate and attach w/ a hurricane clip.

As for the trusses, take a plan layout to your local lumber yard and
have them help you get a truss package put together.

Since this is a structural change many jurisdictions will require a
building permit.
