My ten-year-old Velux window has started to leak in the bottom corner, and the frame is going grey and showing signs of rot. So I investigated and fixed it! I think this is quite a common problem so I hope this simple low-cost repair will help a lot of people. Certainly saves the cost of a new window!
I think the original sealant dries out where the glazing capping profiles overlap because in hot sunshine, the two dark grey aluminium plates soak up heat and get hotter than where there is a single profile against the glass. The glass will allow most of the infra-red to pass through and won't get so hot.
