If we can't find the source of your leak, the investigation fee is refunded.
We've found leaks that other surveyors missed. Our 20+ years of hands-on roofing experience means we know exactly where to look.
Why Roof Leaks Are Often Misdiagnosed
Water does not always enter through the most visible point of damage. It travels — sometimes several metres — along rafters, underfelt, battens and masonry before appearing as a wet patch on your ceiling.
This means a roofer repairing the most obvious area of wear is frequently patching the wrong location. Temporary repairs mask the symptom while the actual cause continues to allow water to penetrate.
Without a proper independent investigation, the cycle of failed repairs continues — and the damage to your roof structure, insulation and internal finishes worsens with every wet season.
Why Patch Repairs Often Fail
Wrong Location
Repairs are made to the most visible problem area, not necessarily where water is actually entering.
No Root Cause
Without a full inspection, underlying issues like failed flashings or valley deterioration go unidentified.
Temporary Fix
Sealants and patch repairs have a short lifespan. Without addressing the cause, the leak returns.
Common Causes of Roof Leaks We Find
Most leaks aren't where you think they are
Flashing Failures
Lead flashing around chimneys, valleys, and penetrations often deteriorates
Tile/Slate Damage
Cracked, slipped, or missing tiles letting water through
Valley Problems
Valley gutters and joints are common leak points
Roof Felt Issues
Torn or perished underlay allowing water into loft space
Parapet Walls
Water penetrating through parapet walls and coping stones
Poor Workmanship
Bad previous repairs causing more problems than they solved
Flat Roof Defects
Blisters, splits, or pooling water on flat sections
Gutter Overflow
Blocked gutters causing water to back up under tiles
Hidden Condensation
Loft condensation mistaken for a roof leak

Why Use an Independent Investigator?
When a roofing contractor investigates a leak, their commercial interest is in the volume of work they can sell. An independent surveyor has no such interest — our only purpose is to find the truth.
