What are asphalt roofing shingles and what is asphalt’s role in roofing shingles?
Asphalt roofing shingles are the most commonly used covering on residential properties in the market.
Asphalt’s primary purpose in roofing shingles is to serve as a waterproofing agent.
Asphalt also holds the granules in place and adds to the overall strength of the roofing shingle.
The best asphalt will stay flexible and will not dry out or become hard or brittle for the expected life of the roofing shingle.
