Adair were instructed by the owners of this newly completed super-prime residential detached property following several incidents of water ingress to the second-floor accommodation.
The main roof construction of the property was conventional and comprised a partial clay-tiled pitch and single-ply membrane with a brick-slip clad decorative GRP fibre-glass prefabricated chimney stack.
Adair carried out an inspection of the flat roof and decorative chimney and provided a report addressing the potential causes of the ongoing water ingress and the consequential effects to the building fabric if left unresolved.
Our survey comprised a visual inspection of the building externally and internally, with no intrusive works or physical investigation carried out. We observed areas of water staining to the ceiling, coving, walls and skirting boards of the second-floor accommodation internally. To the roof, the membrane appeared to have been patch repaired and the chimney stack missing a large amount of pointing. We also identified that the roofing membrane upstand to the chimney stack had not been carried out correctly nor in accordance with the relevant British Standards.
Adair presented their findings to the client and advised on the long-term risks associated to the building fabric with prolonged water ingress in order for them to pursue the main contractor under the terms of their building contract.
