Corrected entry: During the song "Mamma Mia!", when Donna is on the roof of the goat house, you can see that the surface she is standing on is stone or concrete with no gaps in it. But when the camera goes to the three fathers inside the goat house, there is light shining through the ceiling as though it were made of wooden panels. If there was stone on top of the wood, there would be no light coming through.

Correction: It's clear from the outside shots that the roof is indeed made of panels with gaps in between, not concrete. There is, however, a grey rug on top of the panels in a small area, wich makes it look a bit like concrete. But there are still plenty of uncovered panels for the light to come through.
