Get some old clothes on and get ready to get dirty. Now is the time to start inspecting your home and getting it ready for winter. If there are any shingles missing, get them replaced now. Put new roofing cement around pipes and seams. With snow setting on the roof, there is a good chance it will find it's way in if there is a bad spot anywhere. Check your crawl space for clutter and debris. This area should be free so air can flow to keep it dry. Once it starts to get below freezing, then close of your foundation vents. Cut a piece of board insulation to size and seal around the edges. So get ready and get inspecting.
