Roof Leak Repairs
Roof Leak Investigation for Stubborn, Complex Leaks
When simple checks haven't solved it, we investigate the whole system, not one tile.
An investigation goes further than a spot check. It is for leaks that have already beaten one or two attempts to fix them, or where the cause is not obvious. Instead of looking at a single tile, we study the roof as a system -- its design, its history, how the planes and drainage interact -- to work out why water keeps finding a way in. This is detective work, and it is often the difference between finally solving a leak and living with it.
Looking at design and construction faults
Some roofs leak because of how they were built, not just because something has worn out. Roof pitches too low for the tile profile, valleys that are too narrow, box gutters without enough fall, or flashings installed the wrong way round all cause leaks that no amount of patching will cure. An investigation identifies these underlying design issues so we can recommend a real fix rather than another band-aid.
Multiple sources and combined causes
Persistent leaks often have more than one cause working together -- a slightly lifted flashing plus a partly blocked valley, for example, might each be harmless alone but leak badly in combination. We look for these combined causes rather than stopping at the first fault we find, because fixing one and missing the other is exactly why the leak seemed unfixable last time.
Using the roof's history to narrow it down
When a leak started, what the weather was doing, and what previous repairs were attempted all tell a story. A leak that appeared after a renovation points to the new work; one that only started after a big hailstorm points to impact damage. We take the time to understand this history, which often shortcuts the search considerably.
What's Included
- System-wide review of roof design, pitch, drainage and construction
- Investigation of multiple and combined leak sources acting together
- Review of leak history, timing, weather and previous repair attempts
- Assessment of valleys, box gutters, flashings and plane junctions
- Controlled testing to confirm findings on stubborn leaks
- Detailed report explaining the root cause and recommended solution
Frequently Asked Questions
When do I need an investigation rather than a standard leak check?
When a leak has already survived one or more repair attempts, or the cause simply is not obvious. An investigation digs into design faults, multiple combined sources and the roof's history, which a quick spot check does not. It suits complex, recurring or unexplained leaks.
Can a roof leak because of the way it was built?
Absolutely. Low pitch for the tile type, narrow valleys, box gutters without enough fall and reversed flashings all cause leaks by design. These will keep leaking no matter how many times someone patches them, which is why identifying a construction fault is so important.
Why did previous repairs not fix my leak?
Usually because they treated a symptom or found only one of several causes. Combined faults -- like a lifted flashing plus a blocked valley -- can leak together while each looks minor on its own. An investigation is designed to catch what earlier one-off repairs missed.
Do I get a report I can act on?
Yes. You receive a clear written explanation of the root cause, what we tested, and the recommended solution with realistic options. It is useful whether you have us do the work, get other quotes, or need documentation for a builder, strata or insurer.
