In support of Vulpes' point, I have worked on saturated historic buildings, and the drying-out process can indeed cause spalling and other loss of historic wall surfaces. This can be mitigated by applying a sacrifial coat of limewash, so that the evaporation takes place on that surface rather than on the historic masonry. From memory, the sacrificial coat has to be renewed when it flakes until the building is dry, so it's a fairly labour-intensive process.
Repeated flooding can certainly cause damage to masonry - as at Hailes Abbey, where we did some work last year in support of a flood prevention scheme.
