Membrane tie-in
The roofing or wall membrane below should remain continuous beneath the coping.
Metal copings cap parapets, curbs and wall tops to keep water out of horizontal surfaces. They should slope, lock to cleats and accommodate movement rather than depend on face screws and sealant alone.

Direct answer
The roofing or wall membrane below should remain continuous beneath the coping. Cleat design and edge engagement matter at exposed roof perimeters.
These project variables matter because metal copings cannot be reduced to a product name or a single unit price.
The roofing or wall membrane below should remain continuous beneath the coping.
Cleat design and edge engagement matter at exposed roof perimeters.
Splice plates, sealant and expansion joints need enough overlap and movement.
Both sides should project and drip clear of wall finishes.
Work through metal copings in this order so technical requirements are identified before products or schedules are committed.
Confirm membrane, blocking, width and slope.
Provide straight, continuous attachment.
Engage edges and orient joints for drainage.
Use compatible components without locking the entire run.

Verification
Before relying on claims about metal copings, check that the proof relates to the proposed work and is still current. For the coping detail, ask for applicable insurance documents, scope-specific project photographs, current product data and written warranty terms. Confirm that every item relates to the proposed metal copings work rather than to an unrelated job.
Proof must be current. Reviews, certificates and badges related to metal copings should appear only with a traceable source, date and clear relevance to the proposed work.
Use these related resources to test the assumptions behind metal copings from another angle.
Roofing, walls, windows, membranes and masonry must lap in a clear water-shedding order; the distinction matters when applying metal copings to a real building.

For the coping detail, the answer is no: roof slope, substrate, climate, geometry and occupancy can change the right approach. Splice plates, sealant and expansion joints need enough overlap and movement.
Photographs and drawings help separate verified conditions from assumptions in a metal copings discussion. Leak history, product records and known interfaces can turn a broad metal copings inquiry into a usable written scope.
As part of the coping detail, share the building location, roof type, photographs or drawings, current concern and preferred timing. When planning the coping detail, the response can then identify what should be inspected, compared or documented before a commitment is made.
