There are three major categories of Roofing Shingle products available in the market:
Strip Shingles “Strip Shingles are the original and the most basic of roofing shingles available in the industry. Strip Shingles are denoted by the fact that they are single layered roofing shingles that are generally designed to look like slate. Strip Roofing Shingles have a very flat appearance on the roof line and are typically the lightest weight roofing shingles available in the market. Strip shingles used to be the predominant roofing shingle available and used in the market. Today, however, with significant advances in technology and consumer sophistication, Strip Shingles are used primarily by home builders manufacturing economy priced homes or purchased by homeowners as replacement roofing shingles for homes that already have Strip Shingles on the roof. ”
Dimensional Shingles “Dimensional Shingles (or Architectural Laminated Shingles) are now the predominant roofing shingles installed in North America. These products are manufactured as dual layered products (or multi-layered in the case of CertainTeed’s tri-laminate technology) and provide a thicker and richer appearance on the roof (a multi-dimensional look). Dimensional Roofing Shingles also typically are heavier weight than Strip Roofing Shingles and usually have improved warranty protections, which can range from 30-years to Lifetime.”
Premium Shingles “Premium Shingles are usually described as laminated shingles that have a differentiated appearance or functionality from traditional Dimensional Roofing Shingles. These products may have designs that mimic “old-world” roofing shingles, like natural slate or natural shake roofing shingles.”
