Following a roof leak back to the valley
Tracing a recurring ceiling leak to open valley boards, on an investigation near Fraser Rise.
In short: When a ceiling stain comes back after every storm, painting it is a guess. Finding where water enters the roof is the investigation.
What the owner saw
Water marks on a ceiling after heavy rain, painted over and returning.
Starting from the roof
The drone showed the tiled valley; from inside the roof space the valley board had open sides where rain had already been getting in.
What the water did
Mould on the truss timbers nearby, a sign of damp and a roof space without enough ventilation.
A second finding
On this BAL rated home, sections of the fire resistant roof blanket were missing. It was not the leak, but it was recorded.
The outcome
A clear location and cause for a roof plumber to fix, and a report the owner could put to the builder.
