Now I have been told we cannot even carry out the relatively minor repairs, involving re-laying and repointing some barge tiles on one edge, and re-attaching sarking plus a few flashing laps on the other edge. The main part of the roof, including its structure are not affected.
To repair these items we have to replace the roof with a new roof, built to a new pitch, thus requiring a new structure. An alternative offered is to replace the section in question with metal, over half of one townhouse, whilst the rest of the townhouse and complex has a tiled roof.
How can it be that owners of buildings which pre-date current construction codes cannot maintain their buildings?
