Roof System
The trailer roof system includes roof sheet, roof
bows, and fastener connections to the top rail.
Regular roof inspections are important to ensure
safe operation of the vehicle. Wabash National’s
standard roof material is an aluminum sheet or
optional translucent material. The roof structure
is a critical element of the trailer. The roof sheet
and roof bows provide stability to the top rails and
sidewalls.
CAUTION:
Damage to the roof system can cause
instability of the upper sidewalls, resulting in
buckling and collapse of the trailer
• When operating your trailer, ensure proper
clearance so the trailer’s roof will not strike objects
(e.g., bridges, underpasses, garage bay doors,
trees, etc.).
• Prior to loading the trailer, inspect the roof to
ensure it does not have cracks, tears, missing
rivets, loss of bow bonding to the roof sheet and/
or loose roof sheet, or puncture damage.
• Promptly replace damaged or missing roof bows.
• When repairing a roof, always use an aluminum
sheet or similar-type translucent material of the
original thickness.
• During winter use, remove heavy snow and ice
buildup. Parking next to buildings during winter
may increase the chances of heavy snow loads.
• Damaged roofs can cause water leakage,
resulting in cargo damage.
