The roof style question comes up in almost every order call. A buyer wants a 30x50 metal carport, and before the dimensions are even locked in, the question lands: "Which roof should I get?" It's a fair one. Your choice of metal building roof style affects how water drains off the structure, how the building holds up under snow and wind, how it looks sitting next to your house, and what you'll pay. We offer 3 metal building roof styles at Coast to Coast Carports: regular, boxed eave, and vertical. The right pick comes down to where you live and what you're building. Here's how they compare.

The 3 metal building roof styles we offer
We build with 3 distinct roof styles, and each one serves a specific purpose. Panel orientation, internal framing, and eave trim all change depending on which style you choose. Those differences matter the first time your area gets real weather.
Regular roof
The regular roof is our most affordable option. Panels run horizontally from front to back, and the transition from the roof down to the legs has a rounded bend rather than a sharp A-frame peak. There's no eave side trim, no ridge cap, and no hat channel. Less material, less labor, lower price.
It's a reliable choice for mild-weather areas where heavy snow and driving rain aren't seasonal events. A small carport for a riding mower, a basic storage unit in a dry climate, or a simple backyard shed can work well with a regular roof for many years.
What it isn't: a structure built for severe weather. If your area sees heavy snowfall, strong storm systems, or sustained high winds, you'll want to look at the other two options.
Boxed eave roof (A-frame horizontal)
The boxed eave, also called the A-frame horizontal roof, looks more like a standard house roof than the regular style. The peaked A-frame shape and the boxed trim along the eaves give it a cleaner, more finished appearance. Panels still run horizontally, but the overall silhouette reads residential, which matters a lot to buyers installing a building close to their home.
Durability lands between the regular roof and the vertical. It handles moderate wind better than the regular style. The horizontal panels still have a limitation in heavy-snow or persistent-rain climates, though. Water and debris can collect along the horizontal seams over time.
For the buyer who wants the A-frame aesthetic without the full vertical price tag, this is a solid middle option.
Vertical roof
The vertical roof is our top-selling style, and most buyers who research the decision end up here. Panels run vertically from the peak straight down to the eave side rather than horizontally. To support that panel orientation, the structure includes a hat channel running the length of the roof underside. That's the additional framing that makes the vertical roof different in both construction and performance.
Water, snow, and debris shed off a vertical roof naturally. There's no horizontal seam for ice to build in, no overlap for debris to accumulate between cleanings. It's built for areas where weather is unpredictable or consistently severe.
It's also the required style for any metal building 36 feet in length or longer. Past that threshold, a vertical roof is the standard, not an upgrade.

Which roof style fits your climate?
Geography is the biggest variable in the roof style decision. A regular roof that performs well for 20 years in Arizona can become a problem after the first winter in Montana. Three scenarios worth walking through:
Mild weather regions
If your area sees low annual rainfall, no significant snowfall, and modest winds, the regular roof is financially the right call. The Southwest, large parts of the South, and areas where severe weather is rare fit this picture. You're buying what you actually need, without paying for framing your climate doesn't require.
Moderate weather with some wind
The boxed eave fits buyers who want better wind performance than the regular style provides, but who aren't in a region where extreme snow loads are a seasonal problem. Parts of the Midwest, the coastal Southeast, and areas with moderate weather patterns fall here. You get a residential roofline and a step up in weather resistance without the full vertical price.
Heavy snow, rain, or high wind regions
Vertical. If your county gets serious winter weather, if you're on the Gulf Coast or in tornado country, if your property sits open in a field with consistent wind, or if your building length hits 36 feet, vertical is the right decision. The hat channel and vertical panel orientation mean water runs off instead of pooling, and snow sheds rather than building up. The additional upfront cost pays for itself before the second bad season.
Build for your weather, not just your budget. If you need help choosing between regular, boxed eave, and vertical roof styles, call (866) 681-7846 or start with the 3D estimator.
The 36-foot length rule
This one surprises buyers who call expecting to save money by choosing a cheaper roof style. Any metal building with a length of 36 feet or more requires a vertical roof. That's the requirement, regardless of climate or preference.
At that span, horizontal panels can't perform the same way. The length creates flex potential that the vertical orientation and hat channel are specifically built to manage. Horizontal seams also become a structural liability under snow load or sustained wind on longer buildings.
If you're pricing out a 30x40 garage, a 20x50 carport, or a 40x60 barn, you're past the threshold. Vertical roof is the requirement on those configurations.
How roof style affects price
We can't quote specific dollar amounts here because the final price depends on the full building configuration, gauge selection, and your install location. What's reliable to say is how the three styles compare relative to each other.
Regular roofs sit at the lowest price point. Boxed eave adds cost over regular because of the A-frame framing and the added eave trim. Vertical costs the most because of the hat channel and the labor involved in running panels vertically with proper support framing.
Choosing a cheaper roof style for a region that sees real weather tends to cost more in the long run through maintenance, repairs, and replacement sooner than expected. Build for your climate first, then budget from there.

Roof style by building type
The building type shapes the roof decision as much as the climate does.
Metal carports: All 3 styles are available for carports shorter than 36 feet. Vertical is required at 36 feet or longer. For carports in mild-climate areas at smaller sizes, regular and boxed eave remain popular because of the lower price.
Metal garages: All 3 styles work for smaller garages. For a 2-car or larger garage in a climate with real weather, most buyers end up with vertical for the long-term performance and maintenance reduction.
Metal barns: We recommend vertical for barns because of their longer footprints and the demands that agricultural use puts on a roof. Livestock housing, hay storage, and equipment protection all benefit from the superior drainage and structural rigidity the vertical style provides.
Metal RV covers: Most RV cover sizes meet or exceed the 36-foot length threshold, which puts them in vertical territory automatically. Even on shorter configurations, the value of the vehicle underneath makes vertical the right call for most buyers. See this 18x30 metal RV carport as one example of a taller RV storage option.
Metal workshops and commercial buildings: Vertical, across the board.
Frequently asked questions about metal building roof styles
What is the difference between a boxed eave and a vertical roof on a metal building?
The core difference is panel direction and internal framing. A boxed eave roof uses horizontal panels and has an A-frame peak but no hat channel. A vertical roof has panels running from the ridge straight down to the eave side, plus a hat channel along the underside for additional structural support. The vertical style sheds water, snow, and debris more efficiently and performs better under heavy weather loads.
What metal building roof style handles heavy snow best?
Vertical roofs handle heavy snow best. The vertical panel orientation allows snow to slide off rather than accumulate along horizontal seams, and the hat channel provides the structural rigidity needed to support weight during sustained snow events. If your area gets consistent winter weather, vertical is the right choice before anything else.
Do I need a vertical roof on my metal building?
Any metal building with a length of 36 feet or more requires a vertical roof. Below that threshold, you can choose from all 3 styles based on your climate and budget. If you're unsure where your configuration lands, call us at (866) 681-7846 and one of our building specialists will walk you through it.
Can I get a boxed eave roof on a large garage or barn?
The boxed eave is available on buildings shorter than 36 feet, but for large garages and barns, we typically recommend vertical. Longer buildings and higher-use structures benefit from the extra framing and drainage performance the vertical style provides. Many barn configurations also exceed 36 feet in length, which makes vertical the requirement regardless.
How much more does a vertical roof cost than a regular roof?
The price difference depends on the building size, configuration, gauge selection, and install location. What's consistent is that vertical adds the most cost over regular because of the hat channel and additional framing. Boxed eave lands between the two. The most accurate comparison comes from a custom quote. Design Your Building online or call us to get current pricing on the specific size you're considering.
What roof style is most popular for metal carports?
Vertical is our top-selling style across all building types, including carports. Buyers who research the options typically end up there once they understand how panel direction affects weather performance. For shorter carports in mild-climate areas, regular and boxed eave styles remain popular because of the lower price point and the lighter weather demands.
Does roof style limit my color or gauge options?
Roof style doesn't limit your color or panel options. All 3 styles are available with our full selection of colors, including Barn Red, Black, Evergreen, Pewter Gray, Slate Blue, White, and 8 others. Gauge choices of 26- and 29-gauge roof paneling and 12- and 14-gauge framing are also available across all three roof styles. You can also preview color combinations with the 3D Color Planner.
Conclusion
Roof style is one of the earliest decisions that shapes what your metal building will look like, how it handles the weather over its lifetime, and what you pay for it today. Regular works for mild areas and lean budgets on smaller structures. Boxed eave delivers the A-frame look at a mid-range price for moderate weather areas. Vertical is the call for any building 36 feet or longer, any severe-weather region, and any buyer who wants the longest-lasting option with the least maintenance over time.
