Improving your attic insulation is one of the most effective ways to improve home comfort and energy efficiency, especially when it’s hot out. Is it time to update your attic? An under insulated attic can be a serious problem for your home, as it can affect your home's comfort level and can contribute to the creation of ice dams. For many older homes, there is not enough insulation to keep the temperature in check. Fiberglass batts or blown-in insulation may have settled or become less effective over time. In such cases, it is time to install new insulation. The added insulation can lower your energy costs and save money on your monthly energy bills.

Uneven temperature in the home is a clear sign that the insulation in the attic is inadequate. A poorly insulated attic will result in drafts and high energy bills. In addition, it's important to feel the ceilings and walls of various rooms. If you can feel the difference in temperature, your attic may need more insulation.

Poor insulation can also cause your home's temperature to fluctuate without a reason. If you notice these extreme changes in temperature in your home, you may need to make an appointment with a professional who will inspect your attic. If you suspect that your attic is under-insulated, you may also want to consider adding a fresh layer of blown cellulose.

When the attic is not properly insulated, it will let heat from the upper floor transfer into the attic pulling heat from other parts of the house and the furnace kicks on pretty frequently to redistribute the air. the heat transfer from upper floors and ultimately a warm attic can cause ice dams in the winter in the Pacific Northwest. Ice dams can damage the roof and resulting moisture problems may even lead to mold. When this happens, the roof insulation will not be effective enough to prevent the problem.

Having an under insulated attic can lead to uncomfortable temperatures, high energy bills, and condensation that can damage roof components.
