• Question 3

  Needs Grading

  	What are the three parts of an asphalt shingle?
  	Selected Answer: 1. A base material, which may be a fiberglass mat or an organic felt 2. An asphalt body or coating 3. Surfacing granules Correct Answer:   A base material An asphalt body or coating Surfacing granules Response Feedback: [None Given]

• Question 4

  Needs Grading

  	What is the purpose of each component?
  	Selected Answer: 1. The felt or base material is the structure of the shingle that gives its strength 2. The asphalt coating provides the shingle with the ability to resist weathering and remain stable through various temperature swings 3. The ceramic-coated mineral granules protect the asphalt from the ultraviolet rays of the sun, provide the color of the shingle, add weight and may add fire resistance.  Correct Answer: The base material is the structure of the shingle. The asphalt coating resists weathering and adds stability. The granules protect the asphalt from ultraviolet rays, as well as providing the shingles with color, adding weight and fire resistance. Response Feedback: [None Given]
