What is code clearance top and bottom for external doors
There are 2 doors opening onto the exposed roof terrace of a 7 story high block of units. The doors face north and the building is in a coastal area approximately 200 metres from the beach. We are in dispute with a builder over what is the acceptable clearance on the top and bottom of the doors to achieve water tightness from rain and wind . We would like to know if there is a building standard covering this and what clearance should we accept.
The doors were water tight before remediation work and were cut down during the work as the hob beneath had to be raised due to retiling work on the roof terrace.
We believe they were cut too short so increasing the gaps on refitting. The builder saya they are OK but we do not believe so !
