What's the difference between architectural and 3-tab shingles?

Architectural shingles (also called dimensional or laminate shingles) are built from multiple layers fused together, giving them a thicker, textured, more dimensional look that mimics wood shake or slate. 3-tab shingles are a single, flat layer with a simpler, uniform appearance. Beyond looks, architectural shingles are generally heavier, more impact and wind resistant, and come with longer manufacturer warranties, often 30 years or more compared to 20 years for 3-tab. Most Georgia homeowners choose architectural shingles today for the added durability against the state's frequent storms, though 3-tab shingles remain a lower-cost option for homeowners on a tighter budget.
