Architectural ( aka Dimensional) shingles
Architectural shingles are typically 2 separate shingles laminated
together to create a stronger, thicker and more visually appealing
shingle. They are generally more expensive than 3 tab but they will
last longer. These shingles will last 20 to 50 years dependent on the
grade and manufacturer.

Luxury Heavy Laminate shingles
As with the other types of asphalt shingles heavy laminate shingles are
constructed of asphalt, ceramic coated mineral granules and fiberglass
matting. Heavy laminate shingles, however, are built on a heavier base
material and constructed using multiple layers of asphalt material. They
are the heaviest and most durable of asphalt shingles which slows them
to have the highest wind ratings and withstand severe weather conditions.
Flat Rolled Self-Adhering Granulated Roofing
A self-adhering granulated roofing system is an excellent solution
for roofs that are not steep enough for traditional shingles.
These are made of 2 or 3 layers with a granulated top layer similar
to the granules on regular roofing shingles.
The base layer is either nailable or self-adhering (depending on the
specific installation) with a self-adhering mid ply.
