Many homeowners don’t fully understand the link between their attic and energy efficiency throughout the home. If you’re one of them, chances are pretty good that you’re spending a lot more on energy than is necessary. Attics without adequate attention to these three areas are also the source of other big household problems, such as ice dams or indoor moisture problems.

Insulate Properly

Insulation requirements vary widely in different areas, but all attics must have adequate insulation. This is the thermal barrier between your home and unconditioned air, keeping heat inside in the winter and cool air inside during the summer. Without enough insulation, your energy dollars literally go straight through the roof. Discuss your attic with an insulation contractor to learn about recommended attic insulation levels in your area.

Ensure Good Ventilation

Attic ventilation provides a steady flow of fresh air, moving excess heat and moisture out and keeping the air healthy. Toxic compounds may concentrate in an unventilated attic space, plus there’s an added danger of mold and mildew growth, moisture damage and roof ice dams. Check all existing vents to ensure they’re cleared of dirt and debris. Ensure that there are no storage items blocking airflow in the attic. If moisture and heat problems persist, consult a ventilation contractor to troubleshoot the current ventilation system.

Seal Air Leaks

Other than air vents, the attic should be as airtight as possible. Air leaks allow outdoor temperatures and humidity to seep directly into the insulation or your home’s building materials and can also permit dust and other allergens to enter your home. Use a caulking gun around vent or window frames, as well as anywhere you see cracks, dirty insulation or gaps around utility items such as ductwork and chimneys. Consider getting a home energy audit or consult an air sealing professional to seal up any leaks you may have missed.
