Question

1. based on what we can see, what is not a possible problem with the shingle installation below?

options:

• shingles poorly secured
• blistering
• sagging roof frame
• premature shingle failure
• concealed damage

Explanation:

To determine the answer, we analyze each option:

• "Shingles poorly secured" is possible as the shingle is being lifted easily, indicating poor securing.
• "Blistering" (bubbling of shingles due to moisture/trapping) is not visible here. The image shows a shingle being lifted, a roof frame, but no blisters.
• "Sagging roof frame" could be possible if the frame appears misaligned or sagging (visible in the image's frame structure).
• "Premature shingle failure" can result from poor installation (like poor securing) seen here.
• "Concealed damage" is possible as damage under shingles (not fully visible) can be concealed.

So blistering is not a possible problem based on the visible image.

Answer:

B. Blistering
