If you're weighing up VELUX flashing & waterproofing for a property in Knutsford, here's what's genuinely worth knowing first. The flashing — not the window frame — does most of the work keeping a roof window watertight, and VELUX makes different flashing systems for different roof coverings. It's a question we hear regularly from homeowners in Knutsford, and there's usually a specific, fixable cause behind it.
Getting to the Root of the Problem
The right fix depends on what's actually causing the issue, which is why we inspect before recommending anything. Factors we look at include:
- Roof covering type (slate, profiled tile, plain tile)
- Whether the flashing has simply failed or was originally mismatched
- Condition of surrounding tiles or slates
In many cases in Knutsford the underlying cause can be fixed without a full replacement — though for older or badly deteriorated installations, replacement sometimes ends up being the more sensible route.
How do I know if it's the flashing causing a leak?
Damp patches, water staining or drips appearing around (rather than through) the window are the usual signs — we inspect both the flashing and surrounding roof covering to confirm the source.
Can flashing be replaced without replacing the window?
Yes, in almost all cases — flashing work is normally carried out around the existing window rather than requiring a new one.
Why would flashing fail even on a good-quality window?
Flashing that doesn't match the roof covering, or that's simply deteriorated with age, can let water in around an otherwise perfectly serviceable window — which is why matching the flashing to the roof is so important.
