Things to Consider Before Selecting a Shipping Container Roof Kit

When looking for roofing kits for your shipping container, there are a few important factors to consider.

Customizing a Shipping Container Roof Project

Some of the most popular customization options include the length of the roof kit, flooring (for example, simple dirt floor or concrete floor), and accessories.

You can also customize the size of shipping container roofs per your requirements. The majority of the roofing kits available in the market measure 20' in length. However, you can select smaller or larger roofing kits to meet your requirements without compromising on budget.

Cost-Effectiveness of Shipping Container Roof Kit

Compared to traditional construction methods, shipping container rooftop kits provide a more economical choice. They allow you to save on materials, construction, and maintenance.

Unlike fabric covers, steel covers are strong, durable, and less susceptible to wear and tear. This requires minimal maintenance, making them a more cost-effective alternative to the traditional fabric or wood-paneled roofs.

These commercial metal roof systems can be permanent. You can also easily dismantle them and move them to the following job site.

Placement of Shipping Container Roof Kit

You can mount the roofing kits on either the internal edges (inside mount) or external edges (outside mount) of the containers.

The outside mounts offer coverage, protection, and storage on top of the containers. The inside mounts are cheaper as the roofs are narrower and utilize less material.

Laying Foundation for Shipping Container Roof Project

Because cargo containers function as the base for roofing kits, you do not need much time or effort to lay a foundation. However, you should ensure that the ground is level and free of debris, rocks, and trees.

Uneven ground can lead to the building leaning to one side, failing to provide a uniform base for the roof kit.

Maintenance of Shipping Container Roofs

You need to follow a few simple tips to maintain your shipping container roofs:

  • Procure containers from a reputable source.
  • Do not modify the existing roof of a shipping container while installing container rooftop kits. Doing this may compromise the structural integrity of the shipping container.
  • Do not put weight on container roofs. The edges and corners of shipping containers are the reinforced points that provide structural integrity. Putting additional weight on the container roof can lead to flexing.
  • Remove water, snow, or any other elements from the roofs. Long-term exposure to accumulated elements may lead to rust, mold, or moisture intrusion.
  • Remove any dirt, debris, or rust from the container roof. A failure to do so can further damage the container roof and compromise its structural integrity.


Shipping container roof systems are a convenient, speed, and cost-effective way to use existing shipping containers and utilize the unused space between them to create functional and secure storage solutions.

These roofing kits are durable, convenient, and easy to transport from one location to another, making them a preferred solution for secure industrial storage solutions across multiple industries.
