Question Roof Vents

I have a breezeway with 2 roof vents on the west side of the roof between rafters near the peak. The roof does not have soffit vents. The problem I am encountering is when we have a snow storm I always get snow blowing into the vent and settling on the ceiling insulation. Subsequently, When it warms up it drips through the ceiling. How can correct this situation or at least catch the snow?

Covering the top of the vent with fine screen can also prevent a large amount of snow from entering.

The vents already have the downturned cap and an upturned neck on the inside. But it does seem to prevent the snow.

The down turn angle out in front will still help

I don't want to sound stupid, but let me make sure I understand. The vertical leg of the angle touches the roof then? And the angle is only on the lower edge of the vent? My upper edge is closed, the other three are open.

Roof Vents

If you had soffit vents, the roof vents could work as intended and the natural flow could prevent the snow from entering the roof vents.

The flow of air from the wind can cause a suction that draws air up through the roof vents IF you have soffit ventilation.

You got it but the front edge dont have to touch the roof. It also isout some and away from the vent face some
Like Dick said do you have vents in the over hang? This can help.
