If you're weighing up VELUX flashing & waterproofing for a property in Helsby, 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.
What You Need to Know
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.
- Fixes leaks without necessarily replacing the window
- Matched to the specific roof covering (tile, slate, plain tile)
- Addresses the root cause rather than a symptom
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.
