What is Asphalt Made Of?

Asphalt is a sticky and highly viscous liquid or semi-solid material found in nature and is a form of petroleum. Also known as “bitumen,” it can be found naturally in nature, or produced as a byproduct of petroleum processing.

 In ancient times, asphalt was used as a naturally occurring element for waterproofing by the Romans and in other middle eastern civilizations as far back as 800 BC. It was used then to waterproof roofs and coat early weapon to prevent rusting from exposure to the elements.



 Today, asphalt’s primary use is in roads as an asphalt concrete. This accounts for 85% of its use in the United States today. It is also used on airport runways and embankments. The low cost of processing asphalt, its waterproof properties, and sound insulation all make it a favorite choice in major construction. As well, its lifespan is very long and can be resurfaced when worn for very low cost.

 Residential Applications

 In residential building, asphalt is the choice for material in flat roofs, as well as in the manufacturing of roofing shingles and the roofing paper. For residential roofing materials, asphalt is the least expensive, longest wearing material available. It instantly adds waterproofing and sound dampening to its value in home building. This material also has one of the highest temperature variance abilities available, and once heated to 410 degrees Fahrenheit, it becomes an impervious barrier.

 The average cost of asphalt shingles for residential roofing is under $2 per foot, where the next closest material (ceramic shingles) can start at $4-$5 per square foot. Asphalt also lasts longer than ceramic, offers waterproof capability, and lasts twice as long as it’s nearest competition.
