Subject: Low Slope Installation of Exposed Fastener & Snap Lock Panels
(3:12 > slope > 1:12)
Gulf Coast Supply and Manufacturing approves and will provide applicable warranties for the
installation of the following panels on slopes at slow as 1:12: Gulf Rib, 5V Crimp, Gulf PBR,
Gulf Wave, Gulf Lok, Gulf Seam, and Gulf Snap, under FPAs 11650, 11651, 16646, and 18473.
Approval of low slope installation is contingent on the below conditions —
a) Roof layout shall be designed and roof shall be installed to provide an unobstructed
drainage path and shall not create any areas of water ponding.
b) All roof components must be installed in accordance with applicable codes and standards,
and shall be per the manufacturer's recommendations. Note that FBC 1515.2 requires a
minimum slope of 2:12 for metal panel roofs in Dade and Broward County.
c) All recommended accessories (e.g. trim, closures, etc) must be used and installed
according to the manufacturer's recommendations.
d) A continuous i14" (min) bead of Titebond metal roof sealant (or equivalent) or butyl tape
shall be applied in all side laps. Gulf Rib, 5V Crimp, Gulf PBR, and Gulf Wave shall also
have lap screws installed (maximum spacing to match panel screw spacing).
e) A synthetic nail -sealing underlayment tested to ASTM D1970 (Titanium UDL-25, UDL-
30, or equivalent) is required. This underlayment shall be installed as a 2-layer
underlayment per FBC Table R905.1.1 or FBC 1507.1.1, attachment method 1.
f) As an alternative to e) above, an appropriate high temperature peel and stick synthetic
underlayment (Titanium PSU-30, Atlas Weathermaster TU or equivalent) is highly
recommended.
g) Ridge venting is not recommended for low slope applications due to the increased risk of
water penetration.
This memo supersedes all previous low -slope correspondence for the referenced panels. This approval
will remain in effect until superseded, rescinded or until one year after the publication date listed. This
approval may be retroactively applied. If further information is required, please contact Gulf Coast
