Hi, My first floor flat has an exterior roof terrace which appears to be part of the original design of the house (built mid 1860's). The areas consists of two squares each approximately 2.5 metres wide, that overlap by about 90cm accross one corner. Currently the flooring is some kind of thick felt (not like flat roofing felt, it's smooth and appears to be quite thick). The floor is in bad condition, there is ponding, cracks, small lumps and it has become detached from the wall at various points. However the terrace as a whole appears to be solid and well constructed as part of the original house. My father has suggested tiling over it - applying 30cm porecelain tiles using a cement with the appropriate elasticiser directly onto the felt. Half tiles would go up the wall to an appropriate height, covering the damaged flashing and felt. Can anybody offer any advice or suggestions on this? would this work? Or any alternatives? Any help much appreciated.
Thanks and regards,
Simon
