Port Of Baltimore Cruise Terminal

The Maryland Port Authority in 2011 completed a metal-over-metal retrofit of their Port Of Baltimore Cruise Terminal facility. The 65,000 square foot building, located at the Port of Baltimore in Baltimore, Maryland, accommodates passengers embarking on vacations booked with Royal Caribbean, Celebrity and Carnival Cruise Lines to exotic ports of call.

Metal-Fab Manufacturing (Met-Fab) of Jessup, Maryland supplied the entire engineered retrofit framing and roofing package to be installed by Xpert Xteriors of Huntingtown, Maryland. Jamie Fick, Sales Manager for Met-Fab, explained that there was only one way to retrofit the existing metal building and that was to use factory-notched sub-purlins supplied by Roof Hugger, Inc. of Tampa, Florida. Fick added that the benefits of using the Roof Huggers included the ease and speediness of installation, along with the fact that the Huggers actually increase the load carrying capacity of the existing building’s roof purlins - thus compensating for the added weight of the retrofit system package.

Atop the Roof Huggers, Met-Fab’s jobsite roll-formed 22 gauge Met-Fab III double-lock standing seam panels with a bare Galvalume finish were installed. The heavier panel gauge was selected due to the increased wind speed rating required for the facility’s exposure to the Maryland coastline. The Met-Fab III roof system is a 16” wide structural architectural profile panel system with a 2” tall mechanically locked vertical rib. The longest panels roll-formed at the jobsite were 120’-0”.

To increase the thermal resistance of the new roof assembly, fiberglass insulation was installed between the old 12” on center ribbed panel roof and the new roof. Due to the higher wind speeds that the building is subjected to, Roof Hugger designed a special hat-over-zee framing system for the corners and edges of the roof. This permitted the Met-Fab III panel clips to be installed between the existing purlins that were spaced at 5’-0” on center.

The entire installation went smoothly for the Maryland Port Authority because of choosing the right components for the job up front and carefully staging the installation – those components primarily being the Roof Hugger sub-framing and the jobsite roll formed Met-Fab III standing seam roofing.

About Roof Hugger

roof hugger logoRoof Hugger notched sub-purlins enable replacement of new metal roof panels over an old metal roof. They can be used over screw-down or standing seam roof systems and can accommodate new standing seam or screw-down panels. Roof Huggers also maintain integrity of original design loadings; achieve "thermal break" air space between old and new roof sheets; allow for optional insulation; and are laboratory and load tested—with certified load charts.
