A new roof can improve curb appeal and energy efficiency at the same time — fresh shingles give your home a look you’ll love, while ventilation added during the job steadies attic temperature. Coastal Windows & Exteriors is a GAF Master Elite roofing contractor and woman-owned exterior remodeling company with 7,000+ installations completed since 2011, serving 730+ towns across Massachusetts, New Hampshire and Maine.

That dual benefit is a big reason a new roof increases home value. New asphalt roofs return about 68% at resale!

What a New Roof Does for Curb Appeal and Efficiency

Ventilation helps: Proper roof ventilation moves warm attic air out and cuts condensation. Book a free estimate to review your attic.
Curb appeal: Fresh Timberline HDZ shingles renew the roofline, and their 25-year StainGuard Plus warranty guards against blue-green algae staining.
Efficiency link: A balanced attic holds steadier temperatures, and this roof ventilation guide explains the year-round payoff.
Resale and cost: A new asphalt roof returns about 68% at resale, showing how a new roof increases home value. Asphalt replacement averages about $35,701 in New England.
Age matters: GAF suggests a professional replacement conversation once a roof passes 20 years.

Getting Both Looks and Efficiency From a New Roof

Top Recommendation: Pair new Timberline HDZ shingles with balanced attic ventilation for curb appeal and efficiency together. Book a free roof estimate today.
