FROST: Not only is it a sign of the changing seasons, but a helpful indicator as well.
Frost is water v***r that freezes and crystalizes on outdoor surfaces such as grass, plants, vehicles, and roofs.
When we see frost on the roof of our home, we can use it to identify potential issues.
When an entire plane of your roof is evenly frosted over, that can be a good sign that your attic space is adequately insulated.
When your roof is frosted over but there are areas that have melted, that can be a bad sign. It may mean that your attic space is NOT adequately insulated.
The attic space of your home should be roughly the same temperature as the outside (an unfinished attic space that is).
If the insulation is evenly distributed and is the appropriate "R-Value" (thickness), It helps keep the heat where it belongs... in the livable areas of your home.
When there are areas that don't have enough insulation / R-Value, the heat from our homes escapes into our attics and warms the areas of the roof above which in turn causes those melted areas of frost.
In some cases, an attic may have inadequate insulation throughout or perhaps in just a few spaces, perhaps areas that were hard to reach. In other cases, you, or a previous owner, may have had work done in the attic space and the insulation was moved and never put back or became compressed.
Sometimes insulation gets displaced by critters who have found their way in and are making a nice cozy home for the winter. This happens commonly with "loose-fill" or "blown-in" insulation.
The moral of the story is, on those frigid mornings when you see frost on your roof, or neighbors' (their roof that is, not them personally... if that's the case they have bigger issues), use it as a free tool to identify potential insulation issues.
