Question 6

The asphalt strip shingles in a woven valley should extend beyond the center of the valley a minimum of 12 inches.

For proper installation in a woven valley, asphalt strip shingles need to extend at least 12 inches beyond the center of the valley to ensure adequate water shedding and prevent leaks.

A) 6

Selecting 6 inches is insufficient for a woven valley installation. This measurement does not provide enough overlap to effectively channel water away from the valley, increasing the risk of water penetration and potential damage.

B) 12

This option is correct as it meets the minimum requirement for extending asphalt strip shingles in a woven valley. An extension of 12 inches ensures optimal water drainage and enhances the overall integrity of the roofing system.

C) 18

While 18 inches provides more coverage than necessary, it exceeds the minimum requirement. This may not be practical in terms of material use and installation efficiency, making it an incorrect choice for the specified minimum.

D) 24

Choosing 24 inches is excessive for a woven valley. Similar to option C, while it offers significant overlap, it goes beyond what is required, which could result in unnecessary material costs and labor.

Conclusion

The correct answer is 12 inches, as it aligns with industry standards for roofing installation in woven valleys, ensuring effective water management. Other options either fall short of the requirement or exceed it unnecessarily, demonstrating a lack of understanding of proper roofing practices.
