Have a leaking tile roof?
Is it aged over 15 years?
Are the water stains to the ceiling random and spread throughout the home?
Its likely the cause of the issue is leaking tile clips.
We attended a home today, who were experiencing water stains to their ceiling throughout their home. These stains were growing in size each time it rained and were causing significant ceiling damage. On inspection of the roof, it was evident that the roof leaks are coming from leaking tile clips. The internal water stains to the ceiling being throughout the home are consistent with this. These tile clips are well known for leaking and the only way the issue can be resolved is the tile clips are removed and new style tile clips installed. In its current state, the water is being absorbed by the insulation batts and then the moisture is occurring on the ceiling in the roof cavity.
In terms of overall roof maintenance, the following was observed:
These maintenance issues may seem minor, but if left untreated will contribute to major roof leaks and more damage and loss to property.
