Actually, this is the back of the house. We were expecting a storm any minute, but at this time the skies were only partly cloudy, and we had sunshine. However, the wind was pretty boisterous. I wasn't too concerned about the house until I saw this. We've had strong gusts before and nothing like this has ever happened.
About 8:30 I sent in a warranty request to our homebuilder, Fieldstone Homes. I got a call about 10 a.m. and a warranty rep was on our doorstep an hour later to survey the damage. She assured me that they would have a crew on site in the next two days to repair the damage and replace the siding. That was good to hear. Our one year warranty expires in mid-February.
Update: the siding was replaced Wednesday morning before noon, (two days after the damage was done). So everything's back to normal. I'll post pictures later.
