Some ivy types cause
no damage at all.
But, many building
problems can be covered by ivy and repairs to unseen problems not
undertaken.

Am I imagining it, or do the Secretary's guidelines not mention removing
ivy?
And, although I can find lots of local-type recommendations on ivy (see
below) I cannot seem to find any national or industry-wide authority.
Any ideas? Christopher
Appropriate Maintenance
• Keep masonry surfaces free of ivy because
it retains moisture
against the masonry. Ivy also secretes enzymes that
attack the
strength of the lime used in structures built before 1920. It
can
penetrate the masonry surface causing the brick to spall and
possibly
dislodge.
• Remove ivy growing on a wall by cutting it off at the base,
then
allowing the branches to wither completely before gently pulling
them
off the wall.
