Window Leaks: Why Flashing Fails and How to Fix It Properly
Why windows leak into walls, why sealant is never the answer, and what correct window flashing looks like in a Newcastle home.
Service
Leak detection and repair on tile and metal roofs, including flashings, valleys and storm damage.
Most roof leaks are not where the water appears inside. It runs along a batten or a purlin and drops somewhere else entirely. We trace it back to the actual entry point, which is usually a failed flashing, a split valley or a ridge that has lifted, and fix that rather than smearing sealant over the stain.
One leak on an old roof is rarely the only one coming. The screws, the valleys, the ridge bedding and the flashings all went on together, so when one fails the rest are close behind. Patching the drip you can see and leaving the others means paying for the same visit twice. While we are up there we check all of them, tell you what is next in line and what can wait, and hose test the repair before we leave rather than waiting for the next storm.

FAQ
Often it is a flashing or a blocked valley that only overflows in heavy rain, rather than a hole in the roof. It can also be condensation in an unventilated roof space. We check both before quoting a repair.
Yes. We can provide a written scope and quote in the format most insurers ask for, and photograph the damage while we are up there.
