Most of the asphalt used in the United States nowadays is utilized either in paved (green) or flat roofs (red). Asphalt shingle products and systems comprise rolled felt, granulated felt, spray felt, and asphalt-coated metal felt. These products are frequently utilized as roofing components and constitute a good number of the total number of asphalt roofing product sales in the country. The most typical asphalt-to-metal combination includes asphalt shingles made of the materials that are employed to make concrete panels.

Asphalt roofing – Shingles And Application

There are two types of asphalt shingles. One type is created from expanded polystyrene foam and the other one is created from fiberglass. While the former can be more fire retardant than the latter, both types have similar tensile strengths and are often employed in the same applications. Although fiberglass is more fire retardant than asphalt shingles, the former is more fire resistant and proves to be an excellent choice when it comes to colder climate areas such as New England and the Pacific Northwest. In fact, fiberglass has been commonly used to create chimneys and smoke stacks due to its durability, fire resistance, and non-combustible nature. Although fiberglass has become widely used these days, asphalt shingles still remain the most common choice especially in warmer climates.


Rolled or Installed? Both of these asphalt roofing products are made from one or more layers of asphalt. The rolled or installed asphalt layer is then placed on top of a support layer composed of either polyester fiberglass or metal. Both of these provide excellent fire resistance properties as well as resistance to both chemical and physical attack. When choosing between the two types of asphalt roofing products, make sure to pick those with the highest R values and highest thermal resistance.
