Architectural-Shingle Type
Dimensional, architectural (newer term), and laminate (older term meaning “layered”) all refer to the same type of shingle. Dimensional shingles feature a thicker base layer of asphalt-saturated fiberglass. Fused to that solid layer is a tabbed layer, usually with more pronounced notches. The effect is a shingle with a thicker “3D” profile that gives dimensional shingles a slate tile or wood shingle or shake appearance that is more genuine. Dimensional shingles are 32”–34” wide and up to 14” tall.
PROS: Architectural/dimensional shingles cost more than 3-tab shingles, but the appearance is generally favored, especially on upscale homes. Architectural shingles will normally have a longer service lifespan than 3-tab shingles, thanks to their thickness and durability. They also have superior impact resistance thanks to the greater amount of material and wind uplift protection.
Most architectural shingles are rated for up to 110 mph to 130 mph (with enhanced installation) wind uplift, making them a suitable option for high wind and storm-prone areas such as parts of Texas, Louisiana, and Florida.
CONS: A disadvantage is that on low-slope roofs, 3/12 and 4/12 pitch, for example, the higher profile makes them more susceptible to wind uplift. This is an instance where a metal roof could be a more durable option.
Premium or Luxury Shingles
In recent years, ultra-dimensional shingles have come into vogue. Some manufacturers call them premium shingles, though the term architectural shingles is often used too. These are super-thick and heavy shingles, up to 450 lbs. per square (100 square feet). Most have higher profiles and distinct cuts to closely mimic the appearance of genuine slate and cedar shake roofing.
CONS: The premium good looks of these shingles come with a higher price tag.
3-Tab Shingle Type
Roofers refer to shingles as a 3-tab because they are made up of three individual tabs that are 12” wide. 3-Tab shingles come with either 20-year, 25-year, or 30-year warranties. Like architectural shingles, 3-tab roofing shingles are asphalt-based products that work by shedding water to the shingle below.
Your grandparents’ home was probably covered in three-tab asphalt shingles, since for decades that was the only choice. In the 1970s, manufacturers began producing thicker shingles that came to be called laminate, dimensional, and architectural shingles. There’s more to the design than just appearance, so let’s start by exploring each type:
PROS: 3-tab shingles are quite flat and lightweight. They’re +/-30” wide and about 12” tall. The exposed portion of the shingle is notched to produce three tabs that appear separate and are designed to look like slate tiles.
The advantages of three-tab shingles are their lower cost and flat profile, which makes it difficult for the wind to get underneath the shingles or catch and lift a shingle.
CONS: On the flip side, if the strong wind does get under three-tab shingles, their lightweight design makes them more susceptible to tearing.
Most 3-tab shingles are only rated for 60 to 80 mph wind uplift, making them unsuitable for high-wind and hurricane-prone areas.
Another disadvantage is that 3-tab shingles don’t last as long. The oils in any asphalt shingle rise to the top with time and are washed away or dried out by the elements. This makes shingles weak and brittle. The more asphalt there is in the shingle, the longer this process takes. So, roof longevity can be improved for thicker/heavier shingles.
