Question 13

A closed-cut valley is covered by shingles.

A closed-cut valley is a roofing technique where the valley area is finished with shingles rather than other materials. This method provides effective water management and aesthetic appeal.

A) has the valley flashing exposed.

This option is incorrect because a closed-cut valley does not leave valley flashing exposed; instead, it uses shingles to cover the valley, allowing for a more seamless appearance and proper water runoff.

B) is covered by shingles.

This statement is correct as a closed-cut valley is specifically characterized by the application of shingles overlapping the valley area. This method helps to prevent leaks and enhances the visual integration of the roof.

C) is covered with asphalt roofing cement.

This option is incorrect because a closed-cut valley does not involve the use of asphalt roofing cement for its construction. Instead, shingles are employed to create a weather-resistant barrier.

D) requires strip shingles with no cut-outs.

This option is misleading as while closed-cut valleys do utilize shingles, the requirement of strip shingles with no cut-outs is not a defining characteristic of this roofing method. The focus is on the coverage provided by the shingles, not on the specific type used.

Conclusion

The definition of a closed-cut valley clearly shows that it is covered by shingles, making option B the definitive correct choice. Options A, C, and D either misrepresent the characteristics of a closed-cut valley or introduce elements that do not apply to this roofing technique, thus failing to fulfill the question's requirements.
