No one was injured when the roof collapsed at the property in Palma.
The rainfall was heaviest in the Tramuntana mountains around Lluc.
The heaviest rainfall today has been in the Lluc area, which has contributed to the reservoirs overflowing.
Two roads remain closed, there are flood concerns in Campos, Soller and by Albufera, but reservoir levels have increased dramatically.
In Algaida 120 litres per square metre fell, 104 in Palma, 115 in Campos, 103 in Llucmajor and 102 in Portocolom.
