Which of the following is NOT a common type of composite shingles?

Composite shingles are widely used in roofing due to their durability, aesthetic appeal, and variety of styles. Among the common types of composite shingles are 3-tab, T-Lock, and laminated shingles, all of which are designed with efficiency and performance in mind.

3-tab shingles feature a flat appearance and consist of individual tabs cut from a single layer, making them easy to install and a cost-effective choice. T-Lock shingles, on the other hand, have a unique locking design that provides additional wind resistance. Laminated shingles incorporate multiple layers, offering a more dimensional look and improved performance compared to standard shingles.

Curved shingles are not typically recognized as a standard type of composite shingle. While they may exist in niche markets or as specialty products, they do not represent the common categories found in residential roofing applications. Thus, identifying curved shingles as the option that is not a common type highlights the distinction between widely used options and those that are less common in traditional roofing practices.
