How an Energy-Efficient Roof Can Cut Your NJ Utility Bills

Your Roof's Impact on Energy Bills

In NJ, we heat 5+ months and cool 3+ months. The wrong roof costs hundreds extra per year.

Cool Roofing

Materials that reflect more sunlight: Standard dark shingles SRI 10-20, light "cool" shingles SRI 25-40, white TPO flat roof SRI 80-100. Reflective roofing reduces peak roof temp by up to 50°F.

Insulation: The Bigger Factor

Insulation impacts bills more than roofing material. NJ code requires R-49; many older homes have R-19 or less. Upgrading from R-19 to R-49 saves $300-$500/year and costs $2,000-$3,500 (payback in 5-9 years).

Real Savings

Combining reflective materials + R-49 insulation + proper ventilation: 10-15% heating reduction, 15-25% cooling reduction, $300-$700 annual savings, plus extended HVAC life.

Tax Credits

Federal Energy Efficient Home Improvement Credit (Section 25C) offers up to $1,200/year for qualifying insulation and roofing. NJ Clean Energy also offers rebates. Ask your contractor about eligible products.
