winter problems

At the beginning of february 2007 after a violent wind, the carton that was covering the roof (that was a temporarily solution for the winter) have been got off its nails and was going to uncover the roof on large areas. I had to call the roof workers team back.
Another thing... Because nobody was living in the house we were "visited" by unwanted guests, usually kids that were playing with balls in the front of the yard. Other "visitors" were some guys who were parking their truck (they were selling wood for heating). The frustrating part was the feeling that the place is kinda abandoned and I was regulary finding garbage near the fence, in or outside the yard. I was visiting the construction site about twice a week, so the construction site was looking abandoned. I spoke with neighbours and I strengthen the relations with these in hope that were giving an eye by time to time to check if everything is ok.
