If the plant attaches to the render then there is the likelihood of damage.
So either you have a free standing plant that needs no support or you
install a trellis and grow plants up it that will attach there (ie has
tendrils or the stem turns about) instead of having pads (eg ivy) that stick
on to the wall. These pads are a specialised root IIRC. The trellis has to
be strong enough to hold the mature weight of the plant so a few twigs and a
bit of chicken wire may be a disappointment. Some (eg wisteria) can be very
bulky. As for quick growing beware of what you wish for. You may be
setting up for a lifetime of frequent pruning if you choose something that
is over vigorous.

Try buying (or borrow from the library) a book that lists garden species
that has a chapter of climbers and find one that suits your climate and
requirements. Picking one that looks nice but is a bad fit for your climate
will be another disappointment.
