In buildings where this vent design has been used we see pretty clean roof sheathing near the ridge and near the building gable walls, but at the lower roof center and looking down to the eaves, the sheathing will often be wet, moldy, damaged. The sketch at left is an example of the insulation placement and air flow pathway for homes that combine an attic knee wall space with a partial cathedral ceiling space. On some hip roof designs the length of ridge is very short compared with the total roof length.
For roofs that have no soffit or eaves overhang to provide an intake opening, see ROOF VENTILATION INTAKE if NO OVERHANG.

Kevin I'm not sure which vents you mean: if you mean vents under the soffits or eaves, those are intake vents and should be on both front and rear eaves -both sides. If you mean that your roof has several spot vents on both roof slopes, that's ok but I suspect they may still be insufficient. Our recommended books about building & mechanical systems design, inspection, problem diagnosis, and repair, and about indoor environment and IAQ testing, diagnosis, and cleanup are at the InspectAPedia Bookstore. The Illustrated Home illustrates construction details and building components, a reference for owners & inspectors. If you want ventilation then put intermittent blocking behind you fascia board so when you attach it to the shed face there is an air space behind the fascia up into the rafter bay. To do this you need to ask yourself some vital questions so that you have all the answers before you begin construction.
It describes proper roof ventilation placement, amounts, and other details.Intake venting needs to be at the eaves or lower roof edges.
Simply pulling in the needed makeup air from typical gable end wall vents will not move air under the lower and center areas of roof sheathing, thus inadvertently encouraging moisture and mold to form in these areas. It shows the soffit opening along the house wall where wind-blown rain may enter the soffit and wall.
We recommend closing the gable-end vent on older homes that have one, installing a continuous ridge vent to assure air flow between every rafter pair.
Spot vents and gable end vents are a distant second choice for these designs for the reasons I outlined above.
Otherwise the exiting air at the ridge will usually pull its makeup air from the closer gable end vents and not from the soffit or eaves vents.

Otherwise these roof areas will not be dry and cool, and we'll find water damage, condensation damage, ice dams, and often mold in these areas. A better location for this opening would be at the outer edge of the soffit, just behind the fascia! But in any event spot vents are not the most effective way to provide exit venting or exhaust venting for a roof because they do not vent and dry the whole under-roof area.

For the best results we recommend applying construction adhesive between the old and new layers, staggering both the horizontal and vertical seams, and screwing the layers together between the rafters to take any sag out of existing sheathing.The easiest and best way to add ventilation to your roof without getting into the expense of a profile change is installing a venting drip edge.
