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.

Right...

That may or may not be a problem. Some roofing materials are better
than others and as Charles points red roof tiles are probably the worst
of the lot.

However a lot depends on frequency. Signals at the lower end of the band
such as channels 21 to 30 odd are less affected than signals at the top
end of the band are. The aerial itself and cable can make a big
difference as well and that can include the location of the aerial in
the loft relative to the tree/s consider also that there might be extra
height to be had.

Hence the question of where the serving transmitter is so we can get an
idea of the frequencies in use and the likely strength of same.

I have seen an instance where an outside aerial gave grainy and badly
ghosted pictures on analogue, but at the very same location a Loft
aerial has since that time given flawless results on digital TV!.

Yes of course an extended height aerial outside is the "correct"
engineering way to go about this, but the OP may not be able to do that
or may not want to do that.

I few pix posted somewhere would be worth a thousand speculative words
if the OP can do that...
