High up above the functional ceilings in most homes is a mostly dead space filled with insulation, home implements, and sometimes stored stuff. Other than the occasional spider or mouse, your attic may not see a whole lot of life, but this place is vital to the health of your home. if you left last year's leaky roof problem unattended up there and you've recently discovered there's water damage hanging out in the attic, you may be tempted to let the problem go neglected because it is out of sight and out of mind.
