What kind of flashing goes between the roof covering and the sheathing around the roof perimeter?

Counter flashing is utilized between the roof covering and the sheathing around the roof perimeter to protect against water intrusion. It is typically installed along vertical surfaces, such as walls or chimneys, where they meet the roofing material. The design ensures that the water flows over the flashing and onto the roof, effectively directing it away from vulnerable areas. This helps to prevent leaks that can occur at the junction of the roof and walls.

Other types of flashing, while important in their own right, serve different purposes. Step flashing is used where the roofing meets vertical surfaces, creating a series of overlapping sections that shed water. Continuous flashing, on the other hand, is typically installed along eaves or other horizontal transitions. Vent flashing is specifically designed to protect roof vent installations. In this context, counter flashing stands out as the correct answer for its specific role in safeguarding the junction between the roof covering and sheathing.
