Changes near a membrane edge or transition can place stress on details that secure and terminate the roof. The visible gap may be only one part of the condition. A local patch should follow an assessment of adjacent areas.
What to do next
Ask how the contractor will evaluate attachment, transitions, and the extent of movement. Request a repair approach compatible with the existing system. Keep the diagnosis distinct from a blanket assumption that every edge issue requires complete replacement.
