The difference
- Three-tab: a single flat layer cut into three tabs, giving a flat, brick-like pattern
- Architectural (also called dimensional or laminated): two layers bonded together, giving a thicker, textured look
- Architectural shingles are heavier and usually carry better wind resistance
- Architectural shingles hide small dips in the roof deck better
Why it matters in Hampden County
Roofs here face heavy snow, ice at the eaves, summer heat and strong wind from passing storms. A thicker shingle with a stronger seal strip tends to hold up better when wind gets under the edge. Manufacturers usually rate architectural lines for a longer service life than three-tab.
On older houses with slightly uneven roof boards, the textured look of an architectural shingle also makes the finished roof look flatter and cleaner.
When three-tab still comes up
- Matching an existing three-tab roof on a garage or addition
- A historic look on certain older homes
- A short-term roof on a building that will not be kept long
Choosing a color
Darker shingles hide streaking and suit many colonials and capes; lighter ones run a little cooler in summer. In a historic district, color and style may need approval first. See permits and historic districts.

Can I mix architectural and three-tab on one house?
It is possible on separate roof sections, but the look rarely matches well. Most owners do the whole house in one product.
Are architectural shingles heavier on the roof frame?
They weigh more than three-tab, but a single layer on a sound frame is well within normal design loads. Two layers stacked is a different matter.
Is metal a better choice than either?
Metal suits some houses, especially for snow shedding. See asphalt vs. metal roofing.
