Cargo trailer roof

After all the sheet metal has been attached to your trailer, it will then enter the roofing area.

The trailer is pulled between two scaffolds for installation of the roof. The top of the roof bows are prepared with putty or caulking. Roof material comes in large rolls and is pulled from the back to to the front of the trailer. Screws are used to attach the roof material and some factories even apply another sealant such as tape or putty.

There are two types of metal used for roofs. Aluminum or Galvalum.

Aluminum has no seams or coated products.

Brands like Galvalum are made with seams every 4 feet. Galvalum is coated with a unique aluminum and zinc alloy. Due to cost, Galvalum is commonly used by manufacturers although some offer seamless aluminum as an option.
