Strong winds over night tried to rip off the metal roofing that has been in place for over 10 years. Winds last night were 15-25 sustained with gusts up to 39. Not terribly unusual, but this is the first time it has succeeded in lifting the metal roofing. This roof is facing south but exposed to any westerly winds with nothing to block them. This must have been compounded by the winds interaction with the slate roof it joins.
Fortunately this is as far as the lifting of the metal has gotten. I discovered it when walking the dog after getting home from work this morning. The 2X4 seen in the picture was put on following that sighting to help hold this in place until I can repair it properly tomorrow afternoon.
