Because we live in Climate Zone 4, the Department of Energy advises homeowners in the Northern Virginia area to achieve a minimum attic insulation value of R38. Higher R-values mean greater insulating power, but most older homes (and some new homes) have nowhere near the recommended amount of attic insulation in Arlington, VA. To determine if your home would benefit from additional attic insulation to improve efficiency, use a tape measure to determine the depth of the insulation in 10 different locations in your attic. Add the numbers together and divide to calculate the average thickness. If the average number is less than 16 inches, you need more insulation.
If you live in an older home, we recommend that you consider having your attic insulation evaluated as part of a roofing inspection. Roofing & More’s experts can replace compressed insulation or add more insulation, and also ensure proper attic ventilation. We recommend a blown-in insulation system, one of the best and easiest ways to increase the insulative value of your attic.
