During our investigation of the roof coverings, we found that the ledge detail at the front parapet was exposed with no covering installed to prevent ingress at this location.
At the time of the survey, the ledge had a temporary visqueen covering fitted to reduce the ingress to the building. The existing lead coverings to the domes had an incorrect code of lead installed, this had resulted in the movement cracks in the lead panels at various location on the dormers, both defects to the ledge and dormers where the sources of ingress to the building.
We provided the client with recommendations and costs to remove and upgrade the lead to all dormers and install a lead capping detail to the parapet lead to encapsulate the previously uncovered ledge area.
The client was happy with the recommendations and costs and instructed us to proceed with the works.
