Easy Extension of Your Metal Carport Is Possible With Pre Fab Metal Building

Not sure where to park the second car you bought? Or are you simply running out of storage space and can’t find a suitable place to hide your lawnmower? Since making room in your existing carport is not possible, as it is already occupied, perhaps it’s time to get an extension for your metal carport. Can you do that, though?

Carport extension

Yes. A metal carport extension is achievable with additional construction. Usually, metal carports are constructed using single-piece struts that connect the columns and rafters, so extending the width of your existing carport can be quickly done. One way is to remove one end or side walls and extend your structure in that direction. Alternatively, you can extend the length of the carport by removing the side paneling and roof, extending the pad, erecting struts, and replacing sheets. Adding a lean-to to metal buildings is also feasible.

How to Get a Carport Extension

How to Get a Carport Extension

There are several means of getting a carport extension with pre-engineered metal addition. They can be narrowed down to three.

  • Expandable Endwalls

With the installation of expandable end walls in the original carport, you can add bays at the ends of the structure.

  • Side-By-Side-Expansion

In this type of expansion, two gabled roofs have a common wall between them.

  • Second-Story Prefabricated Additions

You can get an extension above if your carport is locked in from all sides. A pre-engineered second-story addition works if your existing carport is sturdy enough to hold the weight of another structure on top of it. You can utilize steel second-floor additions or a canopy-like prefabricated metal carport if the original structure cannot support the additional weight.

Do you Only want to Extend Carport Roofs?

Extend Carport Roofs

Metal carport roofs are comprised of materials that can be easily extended or enclosed. Sometimes, they require minor adjustments to make your carport bigger for additional space. Often, companies that sell carports also offer materials needed for a roof extension. These tools include additional support ports, fasteners, and roof panels. In case you find it challenging to find materials that complement your original carport, consider getting a single shelter and affixing it to the old one. This would make it a leanto, and if you have a lot of room for an altogether different carport, investing in a stand-alone shelter is also a good idea.

With the purchase of a carport roof extension, you will get enough and more space to park your second car or storage space for items meant for outdoor use. Manufacturers can guide you through the process and help you decide on what model to choose from the different styles available and how to go about it. A professional installer or contractor can do it for you, and even if it’s going to cost a bit more money than when you do it yourself, an expert will ensure that the extension is done properly and has followed the building codes of your area.

Carport Extension Ideas On Adding Length to A Metal Carport

  • Remove the side paneling and roof

The first step is removing all the paneling so that you can access the struts while working. You need the sheeting only after the building project is over, so you may keep it aside for now.

  • Extend the pad

In case the slab on which your original carport was constructed is poured concrete, see to it that the slab is long enough to accommodate the additional struts you will be adding to the structure. If you need more stable and leveled ground, consider pouring some extra concrete for the added braces.

  • Erect the struts

You might require only one strut, but you’d need two for RV covers. The struts must be secured to the base just as the original mounts.

  • Replace the metal sheeting

You will have to get new sheeting to cover the extra length.

Adding Width to A Metal Carport Best ideas

Adding Width to A Metal Carport

If you want to extend the width of your carport, the steps are similar to that of extending the length of the structure, but this method would require additional materials. Instead of adding space, you will be practically constructing a second structure. Apart from struts and sheeting, you would also need front-facing sheeting and a gable to hide the space between the struts and extend the roof. Given that your original carport is constructed from columns and rafters in two pieces adding width becomes a tad easier. You would still require extra materials and a gable if the existing carport has a pitched roof.

If you don’t wish to take all that effort to extend the width, then consider adding a lean-to to the side of your metal carport and other structures. This is a convenient option if you don’t mind that your lean-to and original carport don’t visually match and if the existing design has considerable height.

Innovative Way to Add Height to A Metal Carport

You can consider a second-story addition if your original carport has an enclosed design. For this, you must ensure that the structure of your carport is sturdy and stable enough to hold the weight of a pre-engineered second-story addition. This technique is not recommended if your carport is old.

  • Specialty Framing

One way to frame the second story is that the foundation outside the original carport bears the brunt of the outer vertical members of the second story. If done this way, the original frame wouldn’t have a role in supporting the new walls, roof, and flooring. This method would require sufficient foundation space to accommodate the second story. You might even need to hire a concrete crew to get started.

  • Build a new frame

You can also get canopy-like second-floor additions so that the original carport is not duty-bound to support the extra weight.

Heavy Guage Extender Post Kits With Warranty

Additionally, you can get a carport extension by going for extender posts that are sold separately. Heavy gauge steel posts with angular offsets up to 3 feet guarantee additional space to park your car or store heavy equipment. Extender posts that are powder-coated won’t get rusted all that easily or cause the paint to peel. Carport extender posts add a much-needed walkway for convenient entry and exit from your vehicle. The state-approved extender posts with necessary permits and lifetime warranty are widely popular among homeowners for home improvement. These posts can also help you add a lot of free space, preventing the carport from looking overcrowded. Some benefits of getting these installed at your site are as follows.

  • It adds strength to your existing metal carport.
  • Extender poles can help you increase the width of your original carport by up to 3 feet.
  • They can offer the option of installing a privacy screen.
  • The installation process is generally hassle-free. It takes a day or less to get them fixed.

Lifting a Sinking Metal Carport

Lifting a Sinking Metal Carport

You have to pick the right jacks to manage the weight of the carport and get the additional height you are hoping for. Some owners have tried to lift one side of the carport with three large A-frame jacks, work on that side first, and then proceed with the other side.

  • Slab problems

If water drainage leads to soil washing out from beneath the slab, you must reorient the gutters and downspouts to prevent this. A sinking carport slab can be resolved with effective concrete filling, which would help lift the concrete to its previous level and secure it.

  • How To Build a Carport Extension

If you buy a metal building kit, then the guidelines and instructions provided are enough to get you going. A solid foundation is needed. If you want a gravel pad, pier blocks are good. Please ensure the struts are the correct height before securing them to the foundation. Work with the roof support from one brace to the next. Place the roof panels to complete the construction.

Should You Build From Scratch or Expand Existing Carport?

  • What are the Benefits of Metal Carports

Apart from its basic function of protecting your car, a metal carport can help you save money, improve the style quotient of your property, and offer additional storage space. As additional information, carport installation is easy and don’t demand arduous maintenance.

You can extend the length or width of your carport for extra room or get a second-story addition if you have an enclosed structure. Carports and garages serve different purposes. Most opt for carports for their cost-efficiency, but garages can offer extra security for your vehicles and also more storage space. When you turn a carport into a garage, you have to take care of extra costs that would result from buying windows and doors. In addition, if your carport’s primary framing, roof, or ceilings are damaged, even if it’s only slight, you will have to get it fixed, which would mean more expenses.

  • Metal or Wood Carport?

Wood carports are visually appealing, but metal carports score better when it comes to assembly, cost, durability, and maintenance. Galvanized steel, a primary constituent of metal carports, can withstand extreme weather conditions and make the construction durable. Wood carports are susceptible to fire, and metal carports are fire-resistant. Wood carports require a high level of maintenance, whereas metal carports hardly ever require replacement parts.

What to Know Before You Expand Your Carport

  • Purpose of the extension

Whether it’s for parking or more storage space, extending your carport’s width, length or height has perks. Why you really want to get an extension is a question you must be able to answer. If you wish to space for parking a vehicle that exceeds the height of your regular car, you might need only to raise the carport’s roof.

  • Size of the extension

This again depends on the purpose of getting an extension. Based on why you require an extension for metal buildings and other steel structures, you will have to get an extension that is bound to meet your requirements and expectations.

  • Permits for building

Get in touch with the municipality or local government and talk to HOA about getting the necessary permits and approval for extending metal buildings before you can proceed with your carport extension.

  • Placement of a New Add-on

Adding extra width or length can be a bit taxing, so you can also go for a far easier and cost-efficient option of adding lean-tos.

  • Location

Before planning about whether you should or shouldn’t extend your metal building, consider your location. Is it ideal? Are you planning to leave the residential area at some point, or do you see yourself living there for the most part?

  • Land

An extension is only practical if you have the necessary land to accommodate it. Are you in a position where you can buy the land that you need for this project?

  • Local Considerations

Just as you obtained building permits and consulted your local zoning and planning commission before constructing your first metal building, you need to tick these off the checklist before extending your metal carport. The local government or homeowners association might impose certain requirements or restrictions before you can get the extension approved.

  • Additional Considerations

A metal carport can be an excellent way to promote and expand your business. You can start with smaller structures on a tight budget but upgrade it gradually. For future increments, you can increase the frame’s load-bearing capacity. Add structures as your business flourishes.


Getting a metal carport extension is easily achievable if you have the right set of tools and also some expert guidance if you need it. In fact, if you feel like converting your carport to other metal structures, that’s doable as well. You can add a side panel or end panel to make modifications or enclose it to provide better protection for your vehicles. Some of you might like to use your enclosed carport as a workshop, garage, or even an office.
