I planted an ivy the year before last against a house wall,
and it is not about 3 metres high.
It has a trellis up to about 2.5 metres,
but now it is growing above this.
My wife wants to cut it back because she thinks it will damage the house,
but I think that is a myth ...

If left unchecked the roots will get into both the pointing and the
brickwork.
I'll never have ivy growing up against the house again!

Ivy roots will grow into any cracks in walls but it's not likely if
the walls are well constructed. The front of my house is covered in
ivy and there is no sign of any damage. The only problem I have had is
the ivy partially blocks up the gutters and the drainage when rainfall
is very heavy is far from perfect!

It is not a myth - Ivy can cause house damage.
You need to keep it well under control.
Once your drainage is compromised - damp will certainly set in.

Ivy won't damage a soundly built wall; indeed some say that it adds
protection and insulation to a wall, but give it an inch and it will
take a mile. Key things to watch for are:
- gaps in pointing or cracks in brick/stone/rendering
- seals around windows and doors
- vents such as airbricks or those holes all along modern soffits
- pipework - if not soundly attached the weight of ivy can pull it off
the wall; ditto for a satellite dish plus ivy can affect the signal
- trimming it back well clear of gutters and off the roof
Miss something and its roots get in and can then make a tiny problem
much worse. And also worth remembering that whilst it will happily
cling to the trellis you've got, you need to keep an eye on the wall
behind the trellis.
