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.
