Blow the roof off this place

No, really. Yesterday a downdraft or tornado took the roof off of the house of my long time friends, local musician John Husband and his wife Janele. John had just started playing out again, in addition to the Saturday, live online, living room solo gigs.
They are okay. Janele was downstairs and John was nearing the stairway as drywall and other debris started to fall around him.
They are not sure if the structures can be salvaged. Whatever form your positive thoughts, prayers and good vibes may take, please send them out to John and Janele as they figure out what the next steps will be.
