Roof Vents: Decision Time.

I know ... this isn't the most exciting topics.  But this unglamorous topic is staring me in the face.  It's decision time and I'm torn.  See our house?

The middle window above the front door is the second floor kids bathroom; our master bath is on the backside of the house.  Since we are getting a new roof, we decided it would be a good time to put in bathroom vents to eliminate moisture.  Neither bath have vents (which is typical for older homes) and we think it is a smart move to make especially since we're re-doing the roof.  Note: having done our research, there is a small minority that say it's ok to vent to the attic (not outside).  But the vast majority of people say you should vent to the outside through the roof (or gables).  

The issue is this: if we put a vent in the second floor kids bathroom, the only place they can put a roof vent (that'll be effective) is on the front side of the roof.  

And, I'm worried it'll look ugly.  A lot of times it is form over function with me.  I hate to say it, but it is true.  But, the roofing guy assures me it won't be one of those ugly pipe vents that stick out like a sore thumb.  And, it'll be a flat square top vent that should be disguised, like this:  

Is this more than you wanted to know about roof vents?  Yeah, me too.  Anyway, I am still convinced it'll stick out like a sore thumb.  

So yesterday, my husband and I drove around our neighborhood to see if any houses have this flat roof vent on the front side of their roof.  And, we found one.  

Sorry, for the crooked picture, I took it while driving, but do you see the little vent above the top middle window?  That is it.  It is pretty small, no?  Is it really noticeable?  What do you think?
