There are two other major shingle types available in today's market such as three-tab and luxury shingles, featuring the pumpkin-tooth design. Unlike a thicker laminated architectural shingle, the three-tab version only consists of one layer of material making it much more prone to penetration and blow-off. Luxury shingles are the heaviest and thickest by far, making them very durable but also much heavier and higher in cost. In the Northwest, we’ve begun to see a shift away from the more expensive and antiquated luxury shingle, and it has since been replaced with the more cost-effective and technologically advanced architectural shingle.
