The three types of asphalt shingles we test are three-tab, architectural/laminated, and multilayered architectural. Three-tab shingles are the most common. These single-layer shingles are typically rated to withstand winds up to 60 mph and moderate impacts from flying debris or hail. Architectural/laminated shingles have several layers and can withstand stronger winds and weather than three-tab shings. And multilayered architectural shingles are the toughest of the bunch, with some rated for winds of up to 110 mph.
“When you see these shingles up close, it’s easy to see how some of the thicker, multilayered shingles fare better than standard three-tab shingles,” says Misha Kollontai, CR’s test engineer in charge of roofing. “In some cases, the material is so thick you’re getting more than triple the protection you’d get from standard shingles.”
