In 1985, a peaceful revolution occurred in roofing: flat, fragile 3-tab shingles were replaced with architectural shingles- dimensional powerhouses that now cover 75 percent of the American homes. These multi-layered asphalt miracles are also called dimensional (laminated) shingles and are distinguished by strength, resistance to weather, and beauty. But exactly what is architectural roofing shingles? This guide explains why architectural shingles dominate and how to choose the right ones for your home!
Anatomy of an Architectural Shingle: How They’re Made
Architectural shingles are built for performance and style:
1. Layered Construction
- Fiberglass Mat Base:
A waterproof foundation coated with refined asphalt for stability. - Multiple Asphalt Layers:
2–3 laminated sheets bonded together, making them 50% heavier than 3-tab shingles. - Ceramic Granules:
UV-resistant surface layer with algae inhibitors to prevent discoloration.
2. Key Design Innovations
- Shadow Bands:
Darker granules create a 3D effect for visual depth. - Dragon’s Teeth Pattern:
Asymmetric cuts mimic natural slate or wood. - Reinforced Nailing Zones:
Technologies like GAF Timberline HDZ™ boost wind resistance.
