Retrofitting drip edges with a wooden spacer?
You definitely do not want water running down the fascia board. The drip edge is suppose to run the water away from the fascia - wind can kick some water back onto the fascia but most water should be diverted away with the drip edge.
If the drip edge is installed correctly (over edge by about 0.5&quot;, under felt on the eaves and over felt on the rakes), you could try to get a thin piece of material between the drip edge and fascia to provide the spacing needed (you want about a fingers width). If you do that, be careful that the material you use does not wick water up behind the fascia (so make sure that the spacer isn't too close to the bottom of the drip edge).
