Roof and Attic ventilation ports are an important component that often gets overlooked. Often times I see the underside of roof sheathing is black from lack of proper attic-roof ventilation. Many older homes originally had a wood roof which had lots of openings for ventilation but when a new composition shingle roof gets put on ventilation ports are often ignored. Some older style homes have no roof overhang or eaves which make traditional soffit vents difficult. I was very happy to discover Smart Vents from DCI Products on a recent inspection. They have a variety of ventilation products that look nice.
So don't neglect roof-attic ventilation, especially in cathederal ceilings or you might see this!
