Answer :
Final answer:
The correct termination for the bottom of metal counter flashing on a tar and gravel roof against a wall is in a reglet, a groove which directs water away from the intersection.
Explanation:
The question pertains to the installation of metal counter flashing on a tar and gravel roof where it meets a vertical wall. When detailing the termination of counter flashing, it is necessary for effective water-proofing and adherence to best practices in construction.
The correct termination for the bottom of the metal counter flashing on the roof surface, away from the wall, is in a reglet. A reglet is a groove cut into the wall or into the edge of the installation surface, into which the top edge of the counter flashing is inserted and anchored. This ensures that any water running down the wall is directed away from the place where the roof intersects the wall, preventing leaks and potential water damage.
