Roofing Inspection Section#1 Steep Roofing Quiz#8

You should have finished Study Session 7 before starting this study session. This study session covers low-sloped roofs (always tricky), walking on asphalt roofs, and common asphalt roof problems, focusing on the conditions to watch out for.

The estimated completion time is thirty minutes.

Objectives
At the end of this study session, you should be able to:

• List ways of using shingles on low-sloped roofs.
• Describe the problem with sloped roofs.
• Explain the issues around walking on asphalt roofs.
• Discuss problems specific to low-slope roofs (in addition to the general roofing conditions discussed earlier). 

• Question 1

Use conventional shingles but to provide a felt underlayment that is a double layer.  Correct Answer:   Either use specially designed, low-slope shingles, or install conventional shingles over a double layer of felt underlayment. Response Feedback: [None Given]

• Question 2

  Needs Grading

  	In what sense are asphalt shingles particularly vulnerable to ice damming?
  	Selected Answer: Efforts to remove snow and ice dams from the lower edges of roofs often damage the shingles Correct Answer:   The asphalt shingles are easily damaged during the removal of ice dams. Response Feedback: [None Given]
