My freeview reception from my wall mounted aerial on the rear wall was
fine until a neighbours tree grew all of its leaves.

The aerial height is just a bit below the topmost height of the tree.

Would it help if i *tilted* the aerial *up* to point over the tree, or
do transmission signals not work like this?

No they don't. Best bet is to either;

Get your aerial above the tree.

Or,

Reduce the height of the tee

It might be more practical to move the aerial into your loft space if
you have one. Can you say where you are at all and or what the serving
transmitter is?....

Loft would be worse as it would then be faced with the signal being
degraded through the roofing materials.
