Heavyweight dimensional shingles are sometimes called architectural shingles.

• A. They are the lightest shingles available.
• B. They are metal overlays.
• C. Sometimes called architectural shingles.
• D. They are described by color only.

Answer: (C)

Heavyweight dimensional shingles derive their name from their laminated, multi-layer construction that creates a thick, textured, three-dimensional look. That built-up appearance is what the industry identifies with architectural shingles, also known as laminated or dimensional shingles. They’re not the lightest shingles, since the extra layers add weight; they aren’t metal overlays, as they’re asphalt-based products; and describing them by color alone doesn’t capture their defining laminated, dimensional quality.
