The second major repair effort involved the Stone House . The 2011 Virginia earthquake struck the city on August 23 , 2011 , followed by Hurricane Irene on August 26 – 28 . Some tombstones were toppled by the earthquake , and some trees fell over during the storm ( damaging the stone angel in the Memorial Grove ) , but surprisingly little other damage occurred . Major leaks in the Stone House occurred during the hurricane , however , and a post-storm investigation revealed that the clay tile roof needed major repair . Further investigation showed that the leaks had rotted eaves and roof joists . The project , expected to cost $ 75,000 , was completed on November 7 , 2011 , at a total cost of $ 129,500
