Energy efficient roofing helps mainly through ventilation and a tight roof system. With 7,000+ installations completed since 2011, Coastal Windows & Exteriors serves 730+ towns across Massachusetts, New Hampshire and Maine as a woman-owned exterior remodeling company and GAF Master Elite roofing contractor. A new roof works with your attic insulation, not in place of it.

How a New Roof Affects Efficiency

Ventilated system: A properly ventilated roof moves warm air out and protects insulation. Get a free estimate before winter.
Insulation gap: 89% of U.S. homes are under-insulated, per the Insulation Institute. A roof helps, but insulation still matters.
Metal option: Metal can save significant energy compared to asphalt, per Oak Ridge National Laboratory.
Resale return: Asphalt replacements recoup about 68% of their cost nationally, per JLC.
Real bills: Massachusetts households spend roughly $600 a month on energy bills. Fall is the time to tighten up.

Making Your Roof Work Harder This Fall

Top Recommendation: A tight, well-ventilated GAF roof system supports efficiency all winter. Book a free fall estimate.

Better With Insulation: A new roof performs best alongside adequate attic insulation.

Smart for Fall: Install now so the system is ready for heating season.
