(Continued from page 16) manufacture of base mat fbr most inorganic-type shingles. Fiber glass-based asphalt shingles, although somewhat lighter in weight than organic-type shingles are considered to be durable performers in the field, and are usually rated UL Class A. They range in weight from 215 to 300 pounds per square.

Organic-type shingles account for approximately 9004 of U.S. production. but the market share of fiber.glass-based asphalt shingles is growlng.

The design life of most asphalt shingles ranges from 1 5 to 25 years. Generally, the heavier, threedimensional shingles have the longest life expectancy.

The shingles are available in a wide range of colors. White traditionally has been the most popular color, partly because of its ability to reflect heat and lower roof and attic temperatures.

In recent years, however, the popularity of white has waned, while various blends of brown, beige and buff have increased. This trend is due mainly to the rising popularity of the three-dimensional asphalt shingles, which feature earthtone blends almost exclusively. The earthtone trend is also noticeable among the traditional square butt strip shingles, reflecting the tendency in recent years to emphasize environmental tones in exterior decorating.

Fire safety is an important consideration for roofing materials. Underwriters Laboratories. Inc.. an independent, not-for-profit public safety testing laboratory, tests roofings for fire safety. The standard for fire safety for these materials has been established by the UL with the assistance of nationally recognized fire authorities.

Asphalt shingle roofing is classified as .Class C or better. A Class C designation indicates that the roofing material has been tested for light fire exposurethat it will not easily ignite, will not readily support the spread of fire over the roof area. and will not add to the fire hazard by emitting burning brands which can cause new fires.

Class A roof coverings, such as most fiber glass-based asphalt shingles, have been tested against more severe fire exposure.
