Architectural shingles are also asphalt shingles, but they are designed to be stronger and last longer. They are also called dimensional, laminate or composite shingles.

Regular shingles are flat and give roofs a smooth look. Architectural shingles have the textured look of cedar, which helps hide imperfections in a roof’s appearance.
Regular shingles are built to withstand winds up to 60 miles per hour. Architectural shingles are constructed to be sturdier and can stand up against 120 mile per hour winds.
Regular shingles and architectural shingles are vulnerable to sunlight and extreme temperatures, which can cause shingles to crack, split or curl. Water damage allows algae and fungus to grow.
