Most Tulsa homes lose more comfort through the attic than anywhere else. On a July afternoon the roof deck can push attic air past 140°F, and that heat moves down through thin or settled insulation into the rooms below. In January the process reverses, and warm air from inside your house rises through gaps around light fixtures, the attic hatch and plumbing penetrations. Either way, your HVAC system runs longer and your utility bills climb.
Many homes in the Tulsa area were built with 4 to 6 inches of fiberglass batts or loose-fill insulation, roughly R-11 to R-19. Over the years that insulation settles, gets packed down by storage and service techs, or is damaged by roof leaks and rodents. The U.S. Department of Energy recommends R-38 to R-60 for attics in our climate zone, so most older homes are well short.
Tulsa Attic Insulation Experts inspects your current insulation, measures its depth, checks ventilation and moisture, and gives you a free estimate in writing. Depending on your home, the best answer may be air sealing plus blown-in insulation on the attic floor, removal and replacement of damaged material, or spray foam on the roof deck.
Tulsa tip
If your gutters overflow during heavy spring storms, water can back up under the roof edge and soak the insulation along the eaves. Clean or repair gutters before new insulation goes in so it stays dry.
Signs Your Attic Needs New Insulation
- ✓You can see the tops of the ceiling joists when you look across the attic
- ✓Upstairs rooms run several degrees hotter than downstairs in summer
- ✓Energy bills keep rising even though your habits have not changed
- ✓Insulation looks flat, dirty, wet or full of tunnels from rodents
- ✓Drafts or cold ceilings in winter, or ice along the roof edge after a freeze
- ✓Dust streaks on carpet edges, a sign of air leaking from the attic
Choosing the Right Attic Insulation Material
Blown-in fiberglass and cellulose are the most cost-effective way to add insulation to an open attic floor. They fill around joists, wiring and odd framing that batt insulation cannot cover cleanly. Fiberglass resists moisture and settles very little, while cellulose is denser and slows air movement better. Mineral wool, sometimes called rock or slag wool, is a fire-resistant option for specific areas.
Spray foam insulation is the right type of insulation when the HVAC system and ductwork live in the attic, when you have cathedral ceilings or a bonus room, or when air sealing is the biggest problem. Open-cell foam on the underside of the roof deck creates a sealed attic, and closed-cell foam delivers the highest R-value per inch where space is tight. We will explain the trade-offs so you can choose what fits your home and budget.
