Low-slope roof edge · Sherman & DFW
ES-1 edge metal, coping & gravel stop.
Coping, fascia, gravel stop, and drip edge for commercial low-slope roofs — fabricated to ES-1 tested details in 24 ga and any color on our chart.
Fortified Metals fabricates low-slope roof edge metal — coping, two-piece fascia, gravel stop, and continuous cleats — to match ANSI/SPRI/FM 4435/ES-1 tested designs, with documentation for your submittal.
Explained
What ES-1 means.
The roof edge is where wind uplift starts. If the edge metal lets go, the wind gets under the membrane and can peel back the roof.
ANSI/SPRI/FM 4435/ES-1 is the test standard for low-slope roof edge systems. It puts the edge metal, cleat, and fasteners through pull tests to prove they hold against the design wind pressure. The International Building Code references it for edge securement on most low-slope roofs.
A tested edge is a system. The profile, the gauge, the cleat, and the fastener type and spacing all have to match the tested design. That's why we build to the detail, not just the shape.
| Test | What it checks | Applies to |
|---|---|---|
| RE-1 | Holding the roof membrane at the edge | Edges that terminate the membrane, e.g. gravel stop |
| RE-2 | Outward pull on the face | Fascia and coping faces |
| RE-3 | Upward pull on the top | Coping caps |

What to send us
- Building height and location
- Design wind pressure or wind speed and exposure from the drawings
- Roof system — TPO, PVC, EPDM, mod bit, built-up
- Wall or fascia dimensions and nailer details
- Linear footage, corners, and color

What you get back
A price on the edge metal, cleats, and accessories, built to a tested detail that meets the job's wind pressure — plus the documentation your GC or inspector will ask for.
Compliance depends on installing the full system as tested: same profile, gauge, cleat, fasteners, and spacing.
How a custom order works

Questions
Common questions.
What is ES-1 edge metal?
ES-1 refers to ANSI/SPRI/FM 4435/ES-1, the test standard for edge systems on low-slope roofs. It tests whether the edge metal, cleat, and fasteners hold against the wind pressure the building is designed for. Edge metal is called ES-1 compliant when it is built and installed to a design that passed that testing.
When is ES-1 required?
The International Building Code requires edge securement on low-slope roofs (generally under 2:12) to be designed and tested to ANSI/SPRI/FM 4435/ES-1, with gutters excluded. Check with the project's designer or local building department for your job's code edition and any local amendments.
What are the RE-1, RE-2, and RE-3 tests?
They are the three pull tests in ES-1. RE-1 tests how well the edge holds the roof membrane. RE-2 pulls outward on the face of fascia and coping. RE-3 pulls upward on the top of coping. Which tests apply depends on the type of edge.
Is shop-fabricated edge metal ES-1 compliant?
It can be, if it is fabricated and installed to match a tested design — the same profile, gauge, cleat, and fastener spacing. Change any of those and the test no longer applies. Tell us the design wind pressure and we'll match the edge to a tested detail and send the documentation with your quote.
Is ES-1 the same as FM Approved?
No. ES-1 is a test standard. FM Approved is a separate certification program that FM Global-insured buildings may require. If your job is FM-insured, tell us up front so we can confirm what the insurer requires.
Why is the cleat important?
On fascia and coping, a continuous cleat holds the bottom edge of the face and keeps wind from peeling the metal back. The cleat is often a heavier gauge than the cover, and its gauge and fastening are part of the tested design.
