What is the minimum height that eave flashing should extend up the roof inside the interior wall line for low-sloped roofs?

Eave flashing is a critical component in roofing systems, particularly for low-sloped roofs, as it helps to divert water away from the roof edge and prevent water intrusion into the building structure. The minimum height that eave flashing should extend is designed to ensure adequate protection against potential water ingress, especially in areas prone to wind-driven rain or snow accumulation.

In the context of low-sloped roofs, the standard requirement is that eave flashing should extend at least 24 inches up the roof inside the interior wall line. This height is necessary to create a sufficient barrier against moisture that may be transported by wind or splash back from the ground. By extending the flashing to this height, it ensures that any water that makes it past the roof surface is directed effectively away from the building, thereby reducing the chances of leaks or water damage over time.

Flashing height requirements may vary depending on specific building codes or local conditions, but adhering to the 24-inch guideline is a common measure intended to protect the integrity of the roofing system and the overall building envelope.
