Don’t Skylights always leak?
Velux has been making skylights and roof windows for over 65 years and it’s unlikely that they would still be in business if they produced a product that leaked. A properly installed skylight should be problem free for many years. The simple answer though is YES, skylights can leak, but it should be 20 or 30 years before that happens. And the VELUX 10 Year No Leak Warranty assures you of that fact.
