No, I never told you. I just held it in. And now, I miss everything about you. Can't believe that I still want you. And after all the things we've been through. I miss everything about you. Without you. Songwriters: REEVES, JASON / DIAGUARDI, KARA / CAILLAT, COLBIE.
In reality, while asbestos was commonly used in many asphalt roofing materials, asbestos was rarely used in the shingles themselves. It is acknowledged by the asphalt shingle manufacturers that between 1963 and the mid 1970s, some manufacturers did use asbestos in the fiber mat of shingles.
In the United States, asphalt shingles are categorized as either organic-based or fiberglass-based. Organic-based asphalt shingles are manufactured with a base (also termed mat or substrate) made of various cellulose fibers, such as recycled waste paper and wood fibers. This organic base is then saturated with a specially formulated asphalt coating and surfaced with weather resistant mineral granules. Fiberglass-based asphalt shingles are manufactured with mat composed entirely of glass fibers of varying lengths and orientations.
