It might be difficult and our attic is very shallow and we have a hip roof so there really isn’t a peak that is high enough to stand in.
The attic over the part of the old house that we lived in isn’t tall either. We can stand up in the attic here but have to bend over a little.
It’s just really hard to get into the other attic since there isn’t a ladder and that’s the main reason Hubby didn’t want to fool with putting in a fan.
