Keeping Attic Storage Warm for Winter

Storing items in your attic is a great way to use what would otherwise be an empty space, but to make sure they survive the winter, you will need to make sure your attic is properly insulated and ventilated.

Figuring Out Your Attic Insulation Needs

First and foremost, check to see how much insulation your attic needs. Keep in mind that if you have a sloping ceiling, you will need to buy enough insulation for the areas between the rafters. Next, figure out how much it would cost. The older the house, the less likely it is to be adequately insulated. The U.S. Department of Energy's Zip Code Insulation Program website can help you with this stage.

Once you have that figured out, examine your attic to see where the insulation should go. Check your ceiling for exposed joists, gaps, and other signs of damage. These will need to be insulated first. Next, check for signs of moisture. This will help you find smaller leaks and alert you to the presence of mold.


You should also make sure your attic is properly ventilated. Otherwise, it may become too hot, which can be just as dangerous as being too cold. For the best results, get automated vents. They will release cold air automatically when the attic temperature becomes too high.
