In recent years, enhancements to the dimensional shingle have resulted in a new generation of high-quality asphalt roofing products with distinctive, often dramatic, appearances. Architectural roofing shingles provide a stunning three-dimensional appearance and are among the highest quality roofing products made. Because of their extra thickness, architectural roofing shingles weigh considerably more than conventional asphalt-based shingles and have longer warranties. Architect shingles are algae-resistant coated with copper or zinc granules, inhibiting algae growth. Because of their greater thickness, architectural shingles have better wind tear-off resistance. Some are rated at 130 miles per hour.
