Fascia LT installation sequence
ANSI/SPRI/FM 4435/ES-1 edge system: 22 Gauge Cont Cleat, Snap-On Cover, 10' Lengths. 3", 4.5", 6", 8" faces.
This sequence follows Drexel Metals' published installation guide for the system. The project's specifications, the approved shop drawings and the roofing membrane manufacturer's requirements govern; where they differ, follow them and ask AFS.

Step 1 of 4
Installing 22GA Galvanized Cleat
- Apply water cut-off mastic and place the face of the cleat squarely on the edge of the roof membrane, over the wood nailing plate.
- Press it firmly into position and screw through the pre-punched face holes.
- At a miter, miter-cut the cleat into the corner as required to keep a continuous cleat line, then fasten at a minimum 6" in each direction from the corner, or closer at special conditions.
- Butt the cleat ends and apply tube sealant over the butted ends.
As printed in the Drexel guide
“screw through the pre-punched face holes with #10-13x1" S.S. Panhead Woodscrews provided.”
Common mistakes this step guards against
- Do not leave butted cleat ends unsealed - apply tube sealant over them.
- Do not break the cleat line at a corner - miter-cut it so the line stays continuous.

Field checklist
Fascia LT - from Drexel's guide. Tick each item as it is done; print this page for the crew.
Common mistakes
Each line is the reverse of an instruction the Drexel guide states.
- Do not leave butted cleat ends unsealed - apply tube sealant over them. (step 1)
- Do not break the cleat line at a corner - miter-cut it so the line stays continuous. (step 1)
- Do not butt lengths tight - leave the 1/8" gap for thermal expansion. (step 4)
- Do not leave a joint without a splice plate. (step 4)
- Do not cut lengths that leave short sections next to each other. (step 4)
Notes printed on the guide
- Isolate all metal parts from ACQ-treated wood, or any other galvanically incompatible material, with an appropriate membrane.
- Appliance attachments - lightning rods, signs, antennae - that penetrate the water seal, set up a galvanic reaction or otherwise compromise the roof edge system are to be eliminated or isolated, per section 8.0 of ANSI/SPRI ES-1. Isolate appliances from the edge system or do not attach them to it; the lightning protection manufacturer gives the attachment instructions.

- #10-13x1" S.S. Panhead Woodscrew 12" on center through pre-punched cleat hole and membrane
- Water cut-off mastic under the cleat face
