Architectural shingles, also known as laminated or dimensional shingles, are a type of roofing material made up of multiple layers of asphalt-coated fiberglass that are laminated together, giving them their dimensional appearance. They were introduced to the market in the 1970s and 80s to give homeowners a roof that created an architectural interest for the home and could also provide the higher-end look of genuine slate or natural cedar shakes without the added weight, costs, and maintenance. Architectural shingles differ from traditional 3-tab shingles in that they are made with multiple layers of fiberglass mat, which gives them their dimension and aesthetic appeal. They are thicker and sturdier than standard 3-tab shingles and are designed to give your roof a good-looking random pattern or simulate the look of a wood shake roof. Architectural shingles are often described as "high-definition" because of the depth and contour of the individual shingles profile. They are among the highest quality roofing products made and are the most commonly used asphalt roofing material installed on roofs today. Architectural shingles are more expensive than traditional 3-tab shingles, but they offer greater durability and longevity.
