Ever wonder exactly what the difference is between conventional asphalt shingles and architectural shingles? Here's the lowdown: Architectural shingles are essentially just a premium grade of conventional asphalt shingles. They're thicker than conventional shingles and have a textured look that's distinctive.

Conventional asphalt shingles are referred to in the trade as “3-tab”-that is, each sheet of shingles has three tabs or flaps, separated by quarter-inch grooves. They're usually installed in flat, even rows and have a uniform appearance. That's compared with architectural shingles, which have a layered and three-dimensional look.
On average, conventional shingles last about 15 or 20 years. Architectural shingles can remain watertight for up to 30 years, but such quality comes at a cost. Typical architectural shingles cost about 25% more. If you're willing to shell out the extra money, there's little doubt your choice would dress up the appearance of your home exterior.
