Over fascia vents

[mal165]

Hi, my bungalow has had the attic converted to provide 2 bedrooms and a shower room. The soffits have rectangular soffit vents fitted.
I am intending to cap over the eaves and soffit boards using upvc. The fascia boards are in good condition. However I would like to keep the soffits free of vents , the current vents are unsightly and covered in filth.
I am considering using over fascia vents. Would the vents simply fit on top of the existing fascia's or would I have to remove material from the top of the existing fascia to make room for the vents in order to maintain the 'line' of the concrete roof tiles?
Thanks in advance for your advice

A photo of your eaves would be good?

I ask because some roofs are built with overly deep fascias and some with fascias too short. Those that are too short could benefit from some OFV's fixing on top. Experiment with a short piece of 25mm deep batten or some such.

Hi, thanks for the reply. I've taken a couple of pics of the barge boards, tiles and gutters
The fascia's are 225 deep and barge boards 200 deep ( from memory). Will have a closer look and try your suggestion during the week.

You're not giving much away are you....

if its gable to gable, judging by the verge picture which is damaged / or poorly executed I would fit the OFV on the existing fascia without cutting down and then repair the verges nicely.
