Guide for Inspecting your system
This guide will illustrate the minimum requirements of a
roof inspection and provide a basic understanding of some
common details.
Below is a simple roof drawing with penetrations included.
It shows the path followed by Carlisle Field Service
Representatives (FSRs) when they inspect a roof for warranty.
Step 1:
Inspect the perimeter.
Update the roof plan to show the location of all curbs,
penetrations, drains, etc.
Focus on securement and termination.
Mark defi ciencies on the roof plan as they are found.
Step 2:
Inspect all seams on the roof level.
Focus on plate placement and proper seaming.
Step 3:
Inspect all curbs, penetrations, drains, etc.
Focus on one detail at a time, confi rming proper
securement, termination, and fl ashing minimums.
Step 4:
Finally, walk across the roof, update areas in
need of repair, and perform a general check of
the system.
– Roof hatch
– Curb
– Pipe
– Pourable
Sealer Pocket
Quick Reference
Note: This drawing is for your records. Applicators should
complete repairs by the end of each work day.
When the roof has multiple levels, inspect one level at a time.
For larger roof levels, break into smaller sections to eliminate
confusion.
NOTE: CARLISLE EPDM PRIMER MUST BE USED WITH ALL
PRESSURE-SENSITIVE (PS) PRODUCTS.
Additionally, Lap Sealant is required around all edges of PS
Elastoform Flashing
®
.
LAP SEALANT APPLICATION
1. Lap Sealant is required at the following locations:
a. Splice tape overlaps.
b. Beneath and around the outer edge of 6" x 6" PS
T-Joint Covers.
c. Where metal edging joints intersect with PS Cured
Cover Strip.
d. Around all edges of PS Elastoform Flashing, Corners,
and Pockets.
e. Cut edges of reinforced membrane.
2. Procedures:
a. Dusted EPDM must be cleaned 1" (25 mm) on
either side of the splice edge using Weathered
Membrane Cleaner/EPDM Primer and HP Splice
Wipes/a clean cloth.
b. Weathered Membrane Cleaner is not required when
using Kleen EPDM.
c. Apply a
5
/
16
" bead of Lap Sealant centered over the
splice edge. Coverage rate is 22 lineal feet per tube.
d. Feather the Lap Sealant with the specially designed
Lap Sealant Tool so the high point or crown is
centered over the splice edge.
e. Application of Lap Sealant should be completed
each day.

– Drain
– Sleeper
