What should be done with the step flashing after it is installed?

After step flashing is installed, it is important to cover it with counter-flashing. Counter-flashing is crucial as it helps to protect the step flashing from exposure to the elements, particularly water. By directing water away from the joints where the roof meets the vertical wall, counter-flashing prevents potential leaks that could occur if the step flashing were left exposed. It acts as an additional layer of defense, ensuring that moisture does not penetrate behind the flashing, which could lead to rot or structural damage.

While checking for gaps in the flashing is important during installation, and painting might be an aesthetic consideration, these actions do not provide the same protective benefits as effectively covering the step flashing with counter-flashing. Removal is not an option as it would compromise the integrity of the roof's water-shedding capabilities. Therefore, covering the step flashing with counter-flashing is the best practice to ensure long-lasting performance and protection against water intrusion.
