Moisture damage can be a costly result of poor attic insulation
and stagnant attic air. Moisture build-up can weaken your roof rafters, sheathing, wall components, and flooring systems.
In colder climates, during winter months, moisture and condensation can
result in ice dams. Ice dams form at the edge of your roof and over time can destroy your roof, gutters, and all adjacent structures. (see
following flash presentation for more on Ice dams)
Daily activities generate moisture that can pass into your attic. The resulting condensation may also cause mold, mildew, and wood rot. The
average family generates 2-4 gallons of water vapor per day.
Moisture build-up can also contribute to respiratory illness resulting from mold, mildew growth.
Good Insulation will help control moisture transfer into your attic. But insulation alone is not enough. You also need good air circulation in your
attic, year round. Proper ventilation and air circulation in your attic will keep moisture levels low and prevent condensation. |
