1.Fiberglass Mat

Residential Roofing shingles  are reinforced with a thin fiberglass mat, made from glass fibers of specific length and diameter bound together with the help of stable resins and binders. The fiberglass is wound into large rolls at the fiberglass mill, which are then “unwound” at the start of the roofing shingle manufacturing process.

2.Weathering Grade Asphalt

asphalt is the main water-resistant ingredient in shingles. The asphalt used is an end-product of oil refining and, although somewhat similar in origin to road asphalt, it is processed to a higher degree of toughness needed for asphalt shingle performance.

3.Creamic Basalt Grenules

The granules (sometimes referred to as ‘grit’) are processed into a variety of colors via ceramic firing to give them the long-lasting colors used on the exposed part of the shingle. Some shingles feature an algae-resistant granule that helps inhibit discoloration caused by blue-green algae. As well, special “reflective” granules can be used to make roofing shingles that reflect a higher percentage of the sun’s heat energy.
