In the past five months, a metal roof has
been installed on our new log home with
cathedral ceilings in both the great room and the dormer section, i.e., the 40foot
length of the rectangular house.
A damp smell can be detected in the rooms
in the dormer section.
How would the roof be vented?
There is no ventilation in the end eaves,
no soffits under the horizontal eaves, and
we cannot detect any sign of a ridge vent
under the 40-foot metal ridge.
If the ridge is vented, shouldn't we be able to at least see a slight rise between the
roofing sections and the ridge?
Is there any other way this roof could be vented?
How do we determine whether our roof is vented?
From past experience with unvented roofs over catherdal ceilings, I have serious cause to question whether the metal roof is
vented. Help! Thank you. M. Rasmussen

Sounds to me like it isn't vented. If it was vented, you'd see soffit vents as intake and a ridge vent as exhaust.
Ideally, in the rafters, a minimum airspace of 1" would have been maintained between the insulation and the bottom of the decking and that would have been vented with soffit vents as intake and a ridge vent as exhaust.
Your contractor and roofer should be able to answer definitively.
