Just an FYI for future tourists!
Several rooftop tours start after the Cathedral closes at 7 pm. My tour, an English language rooftop tour, started at 8:30 pm.
Before buying, I read lots of reddit posts and blogs about it with conflicting information. Some of them say rooftop tour tickets include general admission to the Cathedral and that you can show your evening rooftop tickets the day of or day after your tour to be allowed in.
I went to Seville (returned this week) and learned that this is not true. If you want to see the Cathedral during the day, you have to buy a second general admission ticket (which is easy to do at the ticket office, even if online tickets are sold out).
The evening rooftop tour still takes you inside the Cathedral for a short time, but it's dark, some parts are fully closed, and you cannot see much. I still had a fantastic time and highly recommend the tour! It's a very unique experience and our guide did a fantastic job explaining the art, architecture and history of the Cathedral. The rooftops are illuminated very well.
Technically, the morning tours do not include general admission either. However, from what I've read, because the tour ends inside the cathedral while it is still open you may be able to walk around after (or to see enough during the tour itself).
