What is the maximum fastening spacing allowed for the drip edge?

The maximum fastening spacing allowed for the drip edge is 12 inches on center. This standard is typically established to ensure that the drip edge is securely fastened to the roof, providing effective water runoff management and protection against water infiltration. Proper spacing helps to maintain the integrity of the roofing system, preventing damage that can occur from wind uplift or other environmental factors. By adhering to this spacing guideline, contractors can ensure that the installation meets building codes and performs as intended, ultimately contributing to the longevity and durability of the roof.
