I have just cut down a wisteria, to prevent any further
damage to the
roof. What could be done to stop it from growing again, for good?
A friend
suggested salt but I am sure there must be a right chemical for the
job.

Tee killer harbicide. If you've cut it down to a stump, recut it so
the cut is fresh and paint the herbicide on straight away while the
cut is still juicy. Use the herbicide undiluted. If there is foliage
showing, spray it on the foliage at the recommended diluted rate.
