what is architectural shingle
Architectural shingles are a premium grade of asphalt shingle roofing. The shingles are thicker and have a distinctive, textured appearance. They are sometimes called dimensional or laminate shingles, and were introduced in the 1970s in an effort by manufacturers to create a higher-end product. Regular roof shingles are called â3-tabâ in the trade, for the 3 tab/flaps with quarter-inch grooves between them in each panel. They run in flat, even rows as opposed to the textured and layered look of architectural shingles.
