Types of Container Roofing Styles

1. Shed-Style Roof for Shipping Containers

The advantages of shed-style roofs are that they are inexpensive, quick to build, and easy to install. They also provide good space for generating solar power.

To install a shed-style roof on your shipping container, you will need to weld right-angled steel plates across the length of each side.

Attach wooden beams to the steel plates on either side of the container roof. Then, screw these trusses into place.

Now, you can attach the purlins or steel bars to provide structural support for your roof. To brace the trusses against the wind, place 20-foot-long purlins (wooden beams) on top of them.

You’ll need a structural engineer to provide the specifics you need. This engineer will help you determine how much weight your roof can support.

This figure varies depending on the climate where your home is located, as it takes into account rain, wind, and snow loads.

Coated steel sheets, galvanized metal, and shingles are all viable options for roof coverage. But the coated steel will last longer than the other two materials.

The final step in the construction process is ensuring that your roof has adequate ventilation. Underneath your trusses, attach a fascia and soffit board.

The soffit board should have at least an inch air gap in the middle, covered with wire mesh that allows air to flow out of the attic space by venting registers or holes punched through between rafters.

To allow for ventilation, cut slots in the gable ends of your steel roof. This will help to prevent heat buildup and rust caused by condensation on the underside of a solid sheet metal ceiling.
