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
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.


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.
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.
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.
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.
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.
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your attic is under-insulated, your insulation becomes wet from a roof leak, you notice mold in the attic, or you have outdated insulation such as cellulose— it is probably time to replace your attic insulation.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. If you’re unsure of what to look for, call a licensed, bonded, and insured insulation contractor like Valentine Roofing for an attic insulation assessment.
