How To Select The Perfect Shipping Container Garage Roof

Selecting the perfect shipping container garage roof can be a daunting task. There are a myriad of choices and settling on something which aligns with your design needs, budget, and personal preferences can be quite challenging.

Below you will find all the information you need to select the perfect shipping container garage roof.

4 Factors to Consider Before Selecting a Container Garage Roof

Container garages provide reasonable durability and they are quick to erect. If you are thinking of creating a garage roof for your container you need to consider these 4 factors…

The Cost

Every roofing style will have a different cost. It’s, therefore, essential to put this into consideration when planning for your roofing project. If you find it difficult to estimate the approximate value of the roof, you may consider consulting a home builder and they will help you determine the cost.

Knowing the cost upfront is crucial as it will ensure that your project will not stagnate due to cash flow problems.

Check the Building Code Restrictions

Every area has its own building code restrictions. Adhering to these regulations is crucial. Check these regulations to confirm whether they allow shipping container buildings and garage roofs.

Consider the Wind Strength

Depending on the roof design, stronger winds may gradually weaken the roof and possibly blow it away. For areas which are prone to strong winds, increasing the structural strength of the roof is key in ensuring safety for all.

There are also specific designs which distribute the wind strength and minimize it’s force. Go for these designs if your area is prone to strong and catastrophic winds.

The Aesthetic Appeal

The roof defines the look and the feel of the final structure. Go for designs which align with your aesthetic tastes and those which harmonize with other roof designs in the immediate area. If you are looking for premium designs, be ready to spend a few extra dollars.

Types of Shipping Container Garage Roofs

Below you will find an overview of the top 10 popular garage roofs.

Gable Roof

This is one of the most common roofs. It is not only suitable for garage roofs but also for the whole house. Its design resembles an isosceles triangle.

Gable Roof

Some contractors will describe it as pitched while others will call it a peaked design. Regardless of what they call it, the design concept is still the same. This design has two roof sections joined at the top, and the planes slide downwards forming a triangular shape.


  • It’s effective at shedding both rain and snow.
  • The Gable roof creates additional storage space.
  • Gable roofs are cheaper to build compared to some of the other roofing designs.


  • The design may be problematic in areas prone to strong winds and hurricanes. Extreme wind can get under the eaves and peel back the roof.

Flat Roof

The flat roof has a small slope to allow proper water drainage. Flat roof designs are more common in areas that don’t receive a lot of snow. The flat roof design gives you an almost leveled surface that you can use to store your tools and other equipment.

The three popular types of flat roofs include the rubber membrane, built-up, and modified bitumen roofing.


  • Flat roofs are easy to install because they don’t have any pitch. Installers are able to navigate and install the roof much faster compared to a pitched roof.
  • Simple to design and fix.
  • Provides extra space for placing solar panels, cooling equipment, and also relaxation place.


  • May pose a problem especially in areas which receive a lot of snowfall.
  • Susceptible to water leakage due to standing water.
  • Needs constant maintenance because of standing water and clogged drains.

Skillion Roof (Slanting Roof)

Also called a mono-pitched roof, features a single sloped roof supported on one side by a tall wall. At first, skillion roofs where mostly found in industrial establishments but nowadays they are forming an essential roofing concept in homes and also in shipping container garage roofs.

If you go with this roof design, you will be able to pick the best pitch for your roof. A minimum pitch will be necessary depending on the material you plan to use for the roof. Asphalt shingles require a minimum pitch of 1:6.


  • Skillion roofs are easy to build, so this makes them very affordable.
  • Has better water drainage capabilities than the flat roof.


  • Not the best design for areas that get hurricanes.
  • You don’t have as much attic space as the gable roof.

Saltbox Roof (Asymmetrical Roof)

This roof is similar to the gable design, but it has one side which slides longer than the other plane. This design comes from the Colonial era.

You may consider this design if you want a mix of vintage designs with modernism. The saltbox roof will give you enough space to store garage equipment and other materials.


  • The design sheds water exceptionally well
  • Has a unique architectural appeal
  • Designed to allow adequate ventilation
  • Easy to insulate without lowering the working height


  • Requires considerably more materials
  • The saltbox roof is a little harder to design and build.

Sawtooth Roof

This roof consists of two or more roofing panels fitted to resemble the shape of a saw blade. It’s common for people to install windows to provide extra natural lighting.

If you have a large garage and you would like to utilize the natural lighting during the day, this roof design may be the best option for you. While this design is quite applicable in manufacturing industries, incorporating the layout in your garage will add more functionality to your garage.


  • Has a stunning architectural appeal
  • Is useful for providing natural light in the garage


  • Requires more time and money to design and build.

Hip Roof

The hip roof slopes on all sides. Unlike the gable roof, which has only two panels meeting at the top, this roof design has all four panels meeting at the ridge.

This design works best for garages which are square in shape but can also work with rectangular-shaped garages.


  • The pyramid design is perfect for areas that experience high winds.
