Skylight opening by itself: temporary solutions
While waiting for the final repair, you can take temporary measures to close and secure the self-opening Velux roof window.
You can close the Velux window by using a closing bar or by pushing it manually until it locks in place. Be careful not to force too much if you notice resistance as this could further damage the mechanism. To prevent the window from opening again, we recommend that you place heavy objects on the window (if you have safe access to it) or surround it with tape to keep it closed.
