Coping, fascia and gravel stop fabrication: principles and terminology
What a coping, a gravel stop and a fascia do, the parts that make up each, the profiles FlashDraft holds, why an ES-1 edge is made exactly as tested, and the hazards in the shop and at the roof edge.
You will be able to: Name the three roof edges and the parts of each assembly, tell a cleat from a clip, explain what "made as tested" means, and state where the shop and field safety limits are.

Coping, fascia and gravel stop fabrication: materials, standards and design constraints
ES-1, ED-1 and the project specification; ED-1 thickness for flat faces and why it is not a wind rating; cleat gauge; galvanic rules; thermal movement and joints; and the AFS limits that decide what can be formed.
You will be able to: Tell the test standard from the design standard and the project spec, pick a face thickness and cleat gauge, keep metals compatible and free to move, and apply AFS shop limits to an edge.

Coping, fascia and gravel stop fabrication: methods and worked application
The fabrication method step by step, the maker allowance on a coping, and five worked examples: girth, the sheet limit, face thickness, thermal movement, and the length and joint plan for a run.
You will be able to: Take an edge order from specification to labelled bundle: choose the route, add the maker allowance, work out girth, thickness, movement and lengths with units, and record each assumption.

Coping, fascia and gravel stop fabrication: defects, verification and case study
What to check before an edge order ships, six correct and incorrect pairs, the defects that recur and their fixes, and a worked case of a returned coping order.
You will be able to: Inspect a formed edge piece against the order and print, diagnose a plausible defect, name the rule it breaks with its source, choose a fix and document the evidence.

Practical task
Prepare a job packet for one coping or gravel stop run: choose the route (a Drexel system as tested, or a custom piece to a shop drawing), size the piece and the run, check it against the sources and AFS limits, and inspect a formed or drawn sample.
Hand in
- A decision rationale: edge type, route (Drexel as tested or custom), ES-1 test that applies, and the governing spec, each with its source
- A marked-up sketch or FlashDraft drawing: legs to the mold line, hems and their face, kicks and drips, top slope direction per the drawings
- Material and measurement assumptions: measured wall, the allowance and whose rule it is, girth with hem allowances, face thickness from ED-1 and the spec, cleat gauge, thermal movement
- A length plan: pieces, joints, gaps or laps as the system prints them, splice plates, corners and end caps, no short closers
- A quality checklist completed for the piece, and a defect analysis for one defect found or seeded: what, the rule and source, the fix, the check that proved it
Rubric
| Criterion | Meets the standard when |
|---|---|
| Sources | Every value names its owner: ES-1, ED-1, the project spec, Drexel or another maker (for its own system only), or an AFS register. |
| Route | A Drexel system is kept as tested (print approval and guide, tested cleat and fasteners, material bought through Drexel per AFS's register); a custom piece makes no ES-1 claim. |
| Sizing | The allowance, girth with hem allowances and the 48 in limit are worked with units, and the FlashDraft status is stated. |
| Thickness and cleat | Face thickness is checked against ED-1 and the spec in decimals, and the cleat gauge against the tested system or ED-1. |
| Movement and joints | Movement is computed, joints follow the maker's printed gap or lap, and there is a splice plate wherever the system calls for one. |
| Defect analysis | The defect is documented with evidence, the rule it breaks, the fix and the verification. |
| Safety | The packet notes point-of-operation guarding and hand protection in the shop, and that roof-edge installation needs fall protection. |
