Although the 'building code' didn't require it 15 years ago, if there is only gable vents, there is probably not enough ventilation. We use ridge and soffit vents now.
Sounds like there is not enough ventilation.
It is not typical to run flashing along the bottom of the roof, by the gutters. It is, however, typical to use 'ice and water shield' in valleys and along the bottom, in areas where icing is common in winter.
