Head flashing is one of those parts of a roof that doesn’t get much attention until something starts leaking. It sits in areas where water naturally wants to get in, usually above windows, doors or roof joins, and its job is to push water away before it has a chance to cause damage. When it’s doing what it should, you won’t even notice it’s there. When it fails, it can lead to ongoing leaks that are hard to track down.
A lot of the time, issues with head flashing come from age, weather exposure or the way it was installed in the first place. Over time, materials can lift, rust or separate slightly, and even a small gap is enough for water to work its way in. Melbourne weather doesn’t help either, with heavy rain and wind pushing water into places it shouldn’t be. That’s why these areas need to be sealed properly and finished with care.
We often find that leaks around windows or wall junctions aren’t caused by the main roof, but by flashing that’s no longer doing its job. It might look fine from the outside, but once water starts getting behind it, the damage can build up over time. That’s why we check how the flashing sits, how it drains and whether it’s been installed in a way that actually suits the roof and wall it’s connected to.
When we carry out head flashing work, it’s not just about covering the area. It needs to be shaped and fitted so water naturally runs away from the joint without sitting or pooling. Getting the angles right and making sure everything ties in with the surrounding roofing is what makes the difference between a quick patch and a long term fix.
If you’ve noticed signs of water getting in around windows, doors or roof connections, it’s worth having the flashing checked sooner rather than later. Left too long, it can lead to internal damage that’s far more costly to repair. Once it’s installed or repaired properly, it blends in with the roof and does exactly what it’s meant to do without causing any issues.
If you’re dealing with leaks around roof joins or openings, getting the flashing checked early can save a lot of hassle. We’ll assess the area and make sure it’s sealed and working the way it should.
