Most Seattle homes are losing precious warmth through under-insulated roofs without even knowing it. That means wasted energy, higher bills, and discomfort that no amount of layering can fix. At the end of the day, you want a home that feels comfortable, efficient, and protected. That’s where we come in. ## Bad Insulation Hurts More Than Just Your Heating Bill You notice it every winter. The house never feels quite warm. You crank the heat, but it’s still drafty. Upstairs is cold, your furnace works overtime, and the monthly energy bill makes your stomach drop. You’ve checked the windows, the doors—even replaced your HVAC. But the real issue? It’s often insulation. An under-insulated roof doesn’t just mean you’re chilly in the winter. It affects your home’s health year-round. - Condensation and Mold: Poor insulation and airflow can trap moisture, leading to mold in your attic. - Roof Damage: Temperature swings and moisture can reduce roof lifespan. - HVAC Burnout: Your system works harder, dies faster, and costs more to replace. - Environmental Waste: You’re paying for energy that escapes into the sky.

On average, when we replace or add insulation to a Seattle home, it costs around $2,000. This is a general estimate for an average-sized home that is low on insulation throughout the attic. Here are some factors that can change the cost: - Attic size: It might cost more or less depending on the size of your attic - Mold remediation: If your attic is moldy, you might need to treat or completely remove the insulation. This will increase the cost. - Type of insulation: Flat roofs require a different type of insulation, which costs a lot more to install. It can add $10,000+ to the total cost.
