Architectural shingles last 25–30 years in Ocean County's climate. GAF Timberline HDZ carries a lifetime limited warranty with proper installation.
Architectural shingles cost ~15% more but last 10+ years longer, offer better wind resistance, and significantly improve curb appeal. For most homeowners, it's the better investment.
We always recommend full tear-off. Layovers trap moisture, void warranties, and hide deck damage. A clean deck means a longer-lasting roof.
