Removing 1930s fascias

I'm working on a 1930s house, the soffits are mostly 100% but quite a lot of the top of the fascias are shot. I attach several pictures you can see the nails in some of them.
How do I go about removing the fascias? What type of timber from Wickes would be suitable to replace them? I'll leave the edge square boards no profile on it. I've put the photos of fascias
on Photo Bucket see , http://s807.photobucket.com/user/EarthT ... %20Fascias
Cheers.

Can't see your link, I'm afraid but do be aware that the facias are likely to be supporting the first course of slates or tiles and the less disturbance there the better.
There's also a good chance that the soffits are fixed to the facia too so do investigate that.
I made my fascias with WBP ply (well treated) and they continue to do ok.

Hi,
Sorry about the link, here it is again,

I think when house was built the soffits were fitted first, then the facias. I took the paint off with a hot air gun. I can't see any nails through the soffits to the facias. Would the ends of the rafters, if that is the correct term would they not do most of the supporting of the first course of slates? I was thinking of drilling around the nails, to release the fascia boards. If they do play a major role in supporting the tiles. Is there some kind of wood filler I could apply to the top of the boards where they are shot, or any other ideas?
See the link for photos. If link still does not come through PM me and I'll send the link.
Thank you.
