Gravel stops, fascia and edge metal · Lesson 1 of 4

Gravel stops, fascia and edge metal: principles and terminology

The vocabulary of roof-edge metal, the parts a Drexel edge kit holds, the three ways a cover engages its continuous cleat, why the cover must stay free to slide, and the fall-protection rules for work at the edge.

You will be able to: Name the parts of a two-part roof-edge system, explain how each Drexel cover engages its cleat, and state the OSHA rules that apply to edge-metal work on a low-slope roof.

Who this module is for

This module is written for the crew that installs roof-edge metal: gravel stops, snap-on fascia and drip edges, with their cleats, miters, end caps and splice plates.

AFS fabricates the pieces. The printed installation guide for the system, the approved shop drawings and the project specification set how they go on.

Videos for this lesson

What this video shows: A short demonstration of installing Carlisle's SecurEdge Standard Fascia, a system its maker describes as having no stripping-in. Another maker's system, not a Drexel edge: on a Drexel job the Drexel guide governs.

Glossary

Gravel stop: A flanged device, commonly metal, designed to keep loose aggregate from washing off the roof (RICOWI definition).
Drip edge: Metal flashing with an outward projecting lower edge that controls where water drips and protects the construction below (RICOWI definition).
Kick out: In RICOWI's glossary, a kick out is a drip shape: the bottom of a vertical flashing angled away from the building, often hemmed to engage a cleat. Drexel's installation guides use the same term for the lower lip of the cleat, which the cover's drip hooks onto.
Splice plate: A short plate, 6 in long in the Drexel kits, placed under the ends of two edge pieces at a joint; Drexel calls for one at every joint.
Roofing work (OSHA): Under 29 CFR 1926.500, the hoisting, storage, application and removal of roofing materials and equipment, including related sheet metal work.
Low-slope roof (OSHA): Under 29 CFR 1926.500, a roof with a slope less than or equal to 4 in 12.
