3-tab shingles, the original standard in roofing, get their name from the single asphalt-coated fiberglass layer that’s cut into three distinct tabs. When installed, these tabs align neatly like puzzle pieces to form a uniform, flat pattern of rectangular shingles.
Because they’ve been around for decades, 3-tab shingles are familiar, easy to install or repair, and typically the most affordable option upfront. However, their popularity has declined due to their plain appearance and their lower durability compared to newer shingle styles.
Architectural shingles use the same asphalt-coated fiberglass construction but include multiple layers. These added layers create more depth, giving the shingles a dimensional appearance and making them thicker and stronger than 3-tab shingles.
Instead of cutouts or individual tabs, architectural shingles feature laminated lower portions and an extra asphalt layer that produces their contoured look. An asphalt sealant bonds the layers together for increased durability.
Overall, architectural shingles are roughly 50% heavier than 3-tab shingles, contain more surface granules, and are generally made with higher-quality asphalt.
