Question 1

Drip edges on steep slope roofs shall be mechanically fastened at a maximum spacing of 12 inches.

Drip edges on steep slope roofs must be mechanically fastened at a maximum spacing of 12 inches to ensure proper installation and functionality. This spacing helps prevent water infiltration and enhances the overall durability of the roofing system.

A) 12 inches.

This option is correct as it aligns with industry standards that dictate a maximum spacing of 12 inches for mechanically fastening drip edges on steep slope roofs. This close spacing is crucial for maintaining the integrity of the roof and ensuring effective water drainage.

B) 18 inches.

This option is incorrect because a maximum spacing of 18 inches exceeds the recommended fastening distance for drip edges on steep slope roofs. Utilizing this spacing could lead to compromised structural integrity and increased risk of water damage.

C) 36 inches.

This option is incorrect, as a spacing of 36 inches is significantly larger than the maximum allowable distance for fastening drip edges. Such spacing may result in inadequate support, potentially leading to failure in the drip edge system during adverse weather conditions.

D) 42 inches.

This option is also incorrect because a maximum spacing of 42 inches far exceeds the established guidelines for fastening drip edges. Such a distance would likely compromise the effectiveness of the drip edge and could lead to issues such as water infiltration and roof damage.

Conclusion

The requirement for drip edges on steep slope roofs to be mechanically fastened at a maximum spacing of 12 inches is essential for ensuring proper performance and longevity of the roofing system. All other options fail to meet the necessary standards and could potentially lead to serious roofing issues, highlighting the importance of adhering to the established fastening guidelines.
