3-Tab shingles are named after their design which has the characteristic 3 tabs, separated by key-way slots on a 1 meter long shingle. They give a roof a uniform, large brick-like appearance. They are manufactured from a single layer of shingle material that is built on either an organic (recycled cardboard) or fibreglass mat substrate. They are covered with porcelain coated crushed granite granules which provide colouration, and UV-ray protection that is essential for durability.
Although, architectural style shingles are now more prevalent, 3-tab shingles offer a pleasing appearance at a cost-effective price. Some homeowners and designers prefer the look of 3-tab shingles on certain styles of homes. For example, the regular and uniform geometric appearance of 3-tab shingles complements Carriage style homes with their block like design and flat gable roofs.
Architectural Shingles (also known as Laminated Shingles)
Architectural shingles are the most popular style of shingle installed in re-roofing applications. Their popularity is due to their pleasing appearance, high durability and wind rating, and Lifetime warranty.
Architectural shingles are constructed from 2 layers of asphalt shingle material that are laminated together, resulting in a raised relief structure that gives a textured appearance to the roof. They are designed to give the appearance of a small cedar shake when viewed from a distance. Some shingles have shadow like bands embedded in the design that enhance the 3 dimensional look of the raised relief structure. Architectural shingles are available in a wide range of options with variations in style, colour, and expected lifetime.
Although architectural shingles cost a little more than 25 year 3-tab shingles, they offer the best value in terms of cost of ownership per year of roof life, higher performance wind rating and increased value to your home from its appearance and curb appeal.
