Fire in garden, can trees be saved?

[Codythedog]

Recently had a fire at the bottom of our garden. A tree surgeon told us the trees will die and eventually go brittle and collapse. I’ve been advised to chop into the tree slightly to see if the tree is still alive but I’ve no idea how to tell. Can anyone guide me based off of the pictures? These are three different trees.

These difference between these 2 pictures is 2 days. Obviously the browner foliage is after the fire.

 No, I doubt very much they’ll survive.

Ask yourself how quickly you need an answer. We can guess and maybe you'll get it cut down, which costs you. Or leave it for a year or two if that doesn't inconvenience you greatly. If it survives, it'll be free. If it does need doing then, it won't be any bigger and you can have been putting a tenner a week away to pay for it.

Srsly? You think cupressus have a snowballs chance in hell of coming back from that?

Not a clue. Never seen one burned like that. The good thing about my suggestion though is that you don’t need to know anything about trees.

I meant no real snark. 
I just think if a homeowner or someone outside the trade comes on asking a genuine question, I like to see them get an informed factual answer, or at least an attempt at one. 
Not misled through ignorance or mischief.

We can't use this persons garden for a bet, but if we could, how much money would you bet on there being no green foliage left after 3 years with no pruning works in or other interventions, just left as they are?

 That scorch may not have completely ring barked the cambium layer.

I take it you've seen fire damaged stuff like that die off over the years in areas where people have left it to see if it survives?

No matter whether it can survive it will be so severely compromised that it will have no amenity value if kept
