Rooftop and Sleeper Deck Systems – Pressure-Treated Framing
» It is recommended that building-code approved
structural material be used as the supports.
» This system should not be allowed to float. It must
be attached in a manner that secures the framing/
system.
» The sleeper system must be level and have no
uneven undulations. Any uneven areas of the
substructure will transfer to the Trex decking,
resulting in uneven decking.
» Trex, when used with a sleeper system, must be
supported below its entire length. If using in a
roofing application, the supports must run the
direction of the pitch of the roof to facilitate proper
drainage. Sleeper should be placed perpendicular to
the deck board orientation.
» For commercial applications, consult a local building
code official for specific requirements.
» If installing decking at an angle, decrease spans
4" (100 mm) for each of the above. (12" (305 mm)
for residential and 8" (204 mm) for commercial.)
» For sleeper systems where small debris (pine
needles, leaves, sand, dirt) can accumulate either
between or under deck boards, a minimum of 1-1/2"
(38mm) height is allowable. Trex recommends
the use of Trex Universal Hidden Fasteners or 2"
Starborn Cap-Tor
®
xd - Epoxy Coated screws.
NOTE: Trex recommended composite decking
screws are too long when using 1-1/2" (38 mm)
height as this will penetrate through the sleeper.
For areas with the potential for debris buildup,
a minimum 3-1/2" (89 mm) or greater height is
recommended to allow the debris to be removed
along with the use of either Trex Universal Hidden
fasteners or any Trex recommended screws.
» Always consult your local building code authority for
proper details on roof and railing installation to the
roof structure if required.
» Any deviation from these recommendations could
result in voiding of the Trex warranty.
A sleeper system is a substructure between a solid surface and Trex decking. Drainage, access, and airflow are
critical. Water must be able to flow through and away from the deck. For repairs and removal of debris, joist system
access may be necessary.
