Features & Benefits

Blown-in attic insulation is safe, sustainable, and essential to the health of your home. Attic insulation can often be installed in just one day. 

Valentine Roofing offers blown-in attic insulation to improve the overall health of any Northwest home. Insulation acts in conjunction with the home’s roof and ventilation to create a system specifically designed to protect your entire home.

  1. Eliminate mold in the attic

    As much as 98% of the moisture in your home is generated in the bathrooms and kitchens. Valentine Roofing’s choice for attic insulation creates a barrier between the warmer, moist air of the home’s interior and the air in the naturally drier attic space. Attic insulation will safeguard against condensation caused by temperature variations and humidity. Reduced moisture in the attic will help to prevent mold and mildew growth in the attic.
  2. Meet code recommendations

    Most attics are under-insulated here in the Pacific Northwest. The Department of Energy (DOE) recommends an R-value between R-38 and R-60 for this area, meaning most homes in Seattle are under-insulated. It was reported by the North American Insulation Manufacturers Association that only 10% of all single-family homes in the United States are properly insulated. Updating attic insulation is cost-effective and easy. It is also a great way to protect your home while meeting DOE recommendations.
  3. Improve energy efficiency

    Attic insulation is essential when it comes to energy efficiency. Insulation helps to maintain consistent temperatures within the home. This will keep your home more comfortable year-round regardless of the outside temperature. By increasing the efficiency of the attic and the home itself the cost of heating and cooling can be lowered by as much as 25% in some cases, earning energy star partner status.
  4. Safety and staying power

    Valentine Roofing’s blown-in insulation received a top fire rating. It does not break down over time like other organic-based insulation and is non-corrosive. All of this has helped to earn this insulation several industry accolades including the GREENGUARD certification. This attic insulation is also guaranteed to sustain its usefulness throughout the life of your home because it will not compress or deteriorate, protecting your home longer.

Home insulation by the numbers: 

  • 98% of the moisture in your home is generated by bathrooms and kitchens
  • 90% of homes are under-insulated
  • 25% potential energy savings from proper insulation

Attic insulation options

  • Top-off service: To meet the recommended insulation levels set by the Department of Energy (DOE), we can either top off the existing insulation or replace it with new blown-in attic insulation. If the existing insulation in your attic is in good condition Valentine Roofing can offer a top-off service. A top-off service is cost-effective as it does not require the removal of the existing insulation. Rather our insulation technician will add insulation to meet DOE recommendations for Seattle, ensuring your attic and your home will be as efficient as possible. However, most attics in the Northwest do need all-new attic insulation because mold, moisture, or pests have made an appearance.
  • Removal of old insulation: Some types of insulation can compact and even break down over time, leaving your home vulnerable. For these homes, Valentine Roofing recommends the removal of old insulation and installation of new blown-in attic insulation that will meet DOE standards. Every attic insulation project includes the installation of baffles for improved airflow as needed. Baffles act in conjunction with intake ventilation. They provide a barrier to the attic insulation to allow fresh, outside air to move freely into the attic as part of the attic’s ventilation system. This is typically a necessary and often overlooked component when installing insulation that keeps the insulation and ventilation systems working together for peak performance.

Common Attic Insulation Questions

How much attic insulation do I need?

The Department of Energy recommends attics in the Seattle area be insulated between R-38 and R-60. For blown-in, loose-fill insulation, this means your attic should have at least 13 inches of insulation and can need as much as 20 inches to meet recommendations.

Will adding attic insulation make a difference?

Considering that most single-family homes in the United States are under-insulated when compared to the Department of Energy recommendations, it is safe to assume that upgrading your attic’s insulation will indeed make a difference in both your home’s efficiency and performance. Putting together the right system for your home will save you money and improve the overall health of your home. Many utilities offer rebates for energy upgrades like this PSE rebate, which saves you up to $2300 when you weatherize your home.

Should I remove the old insulation before adding new insulation?

The best practice is always to remove old insulation to make sure there are not any hidden problems below the fluff. However, if you have insulation that is in good condition and has no past or present signs of pests, mold, or moisture, it might be an option to top off your insulation to the recommended level.

Which type of attic insulation is best?

An attic can be insulated with many different materials. For the best value choose insulation that will not deteriorate over time, is not made of organic material, does not absorb moisture, has top fire ratings, and is non-corrosive. Valentine Roofing always chooses attic insulation that checks all these boxes to keep your home well-insulated while reducing the likelihood of fungi and mold in the attic.

How long does an insulation install take?

For most Northwest attics, installation takes about one day. This includes the removal of old insulation, installation of baffles, and new blown-in attic insulation.

When should I replace attic insulation?

If you think your attic is under-insulated, your insulation becomes wet from a roof leak, you notice mold in the attic, or you have outdated insulation such as cellulose— it is probably time to replace your attic insulation. Ineffective insulation will cost more money in the long run than taking the step to replace it. Checking your attic every 6 months will ensure your insulation is always in tip-top shape.
