Tired of Cold Drafts, High Bills, and a Roof That Can’t Keep Up?

Your Insulation Should Actually Work, Not Just Take Up Space

Everyone knows insulation is important, but are you sure that your roof has enough?

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.

Your Roof Should Be Doing More

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.

We Obsess Over Roof Insulation So You Don’t Have To

Precision. Performance. Nerd-Level Know-How.

We don’t do one-size-fits-all estimates. At RoofSmart, we treat your roof like a living system. Our insulation service begins with a full attic inspection, thermal imaging, and a custom plan built for Seattle’s climate.

Then we get to work choosing the right insulation type, sealing air leaks, and balancing ventilation.

This isn’t just a job for us—it’s what we geek out on. We love helping homeowners stay warm, lower their energy bills, and extend the life of their roof.

How Much Does It Cost to Replace Insulation in My Seattle Roof?

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.

"They were detail oriented ensuring the roof and garage were replaced/ built well. They cleaned up daily when they were through. They addressed concerns as I had them. Nestor and Omar and the whole RoofSmart team were outstanding! I'd highly recommend them to family and friends. I love my new roof and garage!"

Dan S.

"RoofSmart inspected the roof defects and explained everything thoroughly. They provided a copy of the inspection report, complete with the photos of the defects and regulations which the defects didn't meet. They are kind, professional, and skilled. Couldn't ask for more. Highly recommended."

Calvin P.

"They did an excellent job from the estimate through the completion of the new roof and new gutters with downspouts. The new roof looks much better and, most importantly, it will last decades. I highly recommend RoofSmart. They are professional, meticulous, friendly and they do the job right. Thanks, RoofSmart!"
