Big EZ Renovations installs and upgrades roofing insulation for homes and commercial buildings across Greater New Orleans. Proper roof insulation is critical in Southeast Louisiana, where air conditioning runs 8 to 9 months per year. Inadequate insulation forces your HVAC system to work harder, drives up utility bills, and creates moisture problems that lead to mold in attic spaces.

Spray foam is the most effective insulation for Louisiana attics. Closed-cell spray foam provides the highest R-value per inch (R-6 to R-7), acts as a vapor barrier, and adds structural rigidity. Open-cell foam (R-3.5 to R-4 per inch) is more affordable and excellent for sound dampening. Cost: $1.50 to $3.50 per square foot for open-cell, $2.50 to $5.50 for closed-cell.
Blown-in cellulose is made from recycled paper treated with fire retardant. It fills gaps and voids effectively, resists air infiltration, and costs less than spray foam at $0.80 to $1.50 per square foot. It is a good mid-range option for attic floors in New Orleans homes.
Fiberglass batts and blown-in fiberglass are the most affordable options at $0.50 to $1.20 per square foot. However, fiberglass can absorb moisture in humid climates and lose R-value when wet. In New Orleans, fiberglass works best when paired with a proper vapor barrier.
| Type | Cost Per Sq Ft | R-Value Per Inch | Best For |
|---|---|---|---|
| Fiberglass batts | $0.50 – $1.20 | R-3.0 to R-3.8 | Budget projects, wall cavities |
| Blown-in cellulose | $0.80 – $1.50 | R-3.2 to R-3.8 | Attic floors, retrofit |
| Open-cell spray foam | $1.50 – $3.50 | R-3.5 to R-4.0 | Attic underside, sound control |
| Closed-cell spray foam | $2.50 – $5.50 | R-6.0 to R-7.0 | Maximum efficiency, moisture barrier |
For a typical 1,500 sq ft attic in New Orleans, insulation projects range from $750 (fiberglass top-up) to $8,250 (full closed-cell spray foam). The energy savings typically pay back the investment within 3 to 5 years through lower cooling bills.
Costs range from $0.50 to $5.50 per square foot depending on the type. For a 1,500 sq ft attic, expect $750 to $8,250. Spray foam is the most expensive but provides the highest performance and moisture resistance.
The Department of Energy recommends R-38 to R-60 for attics in Climate Zone 2, which includes New Orleans. Most existing homes have R-19 or less, meaning significant improvement is possible.
Closed-cell spray foam is the best choice because it provides insulation and acts as a vapor barrier simultaneously. If budget is a concern, cellulose with a proper vapor barrier is a solid alternative.
Yes, in most cases. Adding blown-in cellulose or fiberglass on top of existing attic insulation is a cost-effective way to increase R-value. We inspect the existing insulation for moisture or mold damage first.
