Ventilation Advice

Opinions required on roof ventilation. I have had UPVC soffit boards put on my roof, and while I was advised by the surveyor who valued my house to have ventilation put in when replacing the soffits but I have conflicting information on where this should be. The guy carrying out the work did not remove the old soffits but rather put the new UPVC soffits over the top. I believe they may have been asbestos, but never having been up there myself I could not confirm this. Anyway, there are no vents along the front or the back of the house but he has put the vents at the sides of the house on the eaves. I questioned this at the time, as not understanding the technicalities of roofing cannot see how they would be effective there. The logic being, that the roof space ends where the roof meets the walls at the side of my house so why would I have vents on the opposite side of the wall to the loft space? He advised that if I had vents at the front and back of my house as well, I would have too much ventilation and this would cause the ceilings in my bedrooms to then sweat and become damp and although he said he was happy to put them in, I would have to sign to say I understood this would happen thus excluding him of any responsibility. I have since been advised that I do need them at the front and back to avoid the timbers sweating and that I could not have ‘too much’ ventilation. Confused…
