I am looking for some guidelines on what I should be paying to have
the roof of my two storey house in Brisbane, Australia restored.  The
tiles are cement tiles, I am told 5 tiles need to be replaced, there
is a very heavy moss coating, the bedding & pointing is in bad
condition (and is causing two leaks).  I think that the roof area of
my property is 246m2 (I may be wrong - but it's a standard sized 3
bedroom home).

The quotes I have received say that they will do the following:
1.  Replace broken/damaged tiles
2.  Pressure clean tiles
3.  Repont & rebed mortar where necessary
4.  Seal tiles
5.  Re-colour

and that they need to set up safety rails around the roof to meet oh&s requirements.
