Upgrade your older VELUX roof windows with the VELUX EL 1000 Slate Replacement Flashing, designed for slate up to 8mm thick. Perfect for replacing pre-April 2001 windows, this flashing allows you to install a modern roof window in the existing aperture without disturbing interior finishes, bathroom tiles, or roof lining. It preserves the integrity of the original installation while providing a secure, durable, and corrosion-proof solution.

With the EL 1000 slate replacement flashing, single window replacements can often be completed in just a day, and in most cases, the work can be done from inside the property.
