Problems from a lack of ventilation:

Without rooftop ventilation heat and moisture can get trapped in the attic and roofing system, which may cause decay of the structure. Additionally, wet insulation in the winter (reflective shingles and coatings are not exempt) and a hot attic in the summer can produce uncomfortable living conditions and higher energy bills.

Proper rooftop ventilation provides:

The release of excess heat and humidity from the building envelope.
