Asphalt Shingles come in two standard design options: Architectural (Dimensional) Shingles, and 3-Tab Shingles. 3-Tab are essentially flat simple shingles with a uniform shape and size. 3-Tabs are thinner, and do not last as long or offer Manufacturer's Warranties as long as Architectural Asphalt. Dimensional, or Architectural Shingles are thicker and stronger, and they offer more aesthetic appeal with their "dimensional" look with more shadow and varied shapes and sizes. While more expensive to install, they come with longer Manufacturer's Warranties, sometimes up to 50 Years. Dimensional Shingles will stand up better to the elements, and offer you less potential for leaking (and the high costs of the damage that can come with roof leaks), typically for a longer period of time. While 3-tab shingles typically need to be replaced after 5–18 years, Dimensionals typically last 24–30 years.
