The timber frame additions each had antique hewn rafters that we would expose on the interior.
The log cabin though would have an attic space which would be used for personal storage and air handler equipment, so we would build a roof here using new lumber.
I’ve never assembled a roof using “engineered roof trusses”. I know, all the paperwork says that they are just as strong, or even stronger, than properly sized rafters, but they look wrong, they eat up the attic space, and well, I simple don’t trust them to hold up for centuries.

Engineered roof systems while strong are incredible dangerous in fire conditions! For example in attic fire conditions the roof is likely to collapse within 1 min of the smoke alarm sounding on the story immediately more below the attic! Not allowing the necessary time required to evacuate the structure!
I fully agree with that… I was told years ago that any fireman would refuse to enter a burning house that had engineered floor joists.
