The best RV carport for high winds and snow is a custom-engineered steel RV carport with a vertical roof, certified wind and snow-load ratings, a reinforced frame, and the correct anchors for your site. Open-sided coverage can work in moderate conditions, but many RV owners in exposed, snowy, or coastal regions benefit from added side panels or a fully enclosed design.

What Makes an RV Carport Strong Enough?
The best RV carport is not simply the largest model or the one with the heaviest-looking frame. It is a structure designed around your RV’s dimensions, your property’s conditions, and the wind-speed and snow-load requirements enforced where you live.
For customers across the United States, that can mean planning for lake-effect snow in the Midwest, winter accumulation in the Rockies and Northeast, heavy rain in the Pacific Northwest, or high-wind exposure in coastal and plains communities. A building that works well in a mild inland climate may need meaningful upgrades in a county with higher engineering requirements.
Our RV carports can be customized with the roof style, leg height, anchoring, bracing, panels, and certifications your location requires. American Carports, Inc. structures can be engineered to meet specific wind-speed certifications required by local building departments, so it is important to confirm local requirements before you place an order.
Why Is a Vertical Roof Best for Snow?
A vertical roof is generally the best choice for an RV carport in snowy climates because its roof panels run from the ridge down to the eaves. This orientation helps snow, rain, and debris move off the roof more efficiently than a horizontal-panel roof.
Vertical roofing is especially worthwhile when your property experiences frequent snowstorms, wet snow, ice buildup, pine needles, or leaf debris. Snow can still accumulate during severe weather, but directing runoff down the slope reduces the chance that debris will sit across the roof ribs and trap moisture.
American Carports identifies a vertical roof as the best roof choice for snowy climates, with heavier steel, proper snow-load engineering, and adequate leg height among the important design priorities. A vertical A-frame roof is also designed to help snow, dirt, and rain shed more easily.
Should You Choose an A-Frame Vertical Roof?
Yes, in most high-wind or snow-prone locations, an A-frame vertical roof is the upgrade worth making. The roof profile gives the building a more traditional appearance, while vertical panels offer better water and snow shedding.
Choose an A-frame vertical roof when you want:
- Better runoff in rain, snow, and ice conditions
- A cleaner-looking roof with less debris collection
- A stronger long-term choice for a large RV footprint
- A more polished appearance next to your home, cabin, or business
- A practical design for a structure with added side panels or enclosed storage
For an RV carport, the roof is protecting a large investment. Spending more up front on a roof system designed for your weather conditions can be far less costly than dealing with water intrusion, excessive snow accumulation, or damage from a poorly matched structure.
How Important Are Wind Certifications?
Wind certification is one of the most important details when buying an RV carport for a windy location. A certified structure is engineered to meet a specified wind-speed requirement, which may be set by your county, municipality, HOA, or building department.
High winds do not only affect the roof. Wind pressure can lift the roof, push against side panels, strain the legs, and pull at anchors. That is why the entire system matters: frame, bracing, anchor method, roof configuration, panels, and site preparation must work together.
American Carports, Inc. can engineer structures to meet location-specific wind-speed certifications, including 90-mph and higher ratings when those requirements are specified during ordering. Ask your local building department what wind certification, drawings, permits, setbacks, and anchoring standards apply to your exact address before finalizing your design.
What Features Help in High Winds?
A high-wind RV carport should be configured for more than basic overhead shade. Consider the following upgrades and requirements:
- Certified engineering: Order the wind certification your county or municipality requires.
- Correct anchors: Your anchor system must match whether installation is on concrete, asphalt, soil, gravel, or another approved surface.
- Reinforced bracing: Additional bracing helps the structure resist lateral movement during gusts.
- Heavier steel framing: A heavier-gauge option may add useful strength for demanding sites.
- Strategic side panels: Panels can reduce wind-driven rain and snow entering the carport, but they also change wind loads, so they should be included in the engineered design.
- Proper orientation: Positioning the opening away from prevailing winds can improve day-to-day protection where site layout permits.
- Appropriate height: Taller RV buildings need careful engineering because a high roof experiences more wind exposure.
Anchoring is particularly important in sandy, loose, or coastal soils, where deeper or wider footing systems may be needed. Never assume that a basic anchor package is sufficient for your location; let local requirements and site conditions guide the design.
What Snow-Load Rating Do You Need?
The snow-load rating you need depends on your local building code and the ground snow load at your property. There is no universal “best” snow rating because snowfall differs dramatically from one region to another, and elevation can change requirements even within the same county.
For example, a customer in a low-snow part of Tennessee may need a different configuration than someone in northern Michigan, western New York, Colorado, Montana, or a mountain community in California. Your local jurisdiction may also require a permit and engineered plans for a structure of a certain size.
Snow-load performance is managed through factors including truss spacing and steel gauge. In areas with higher snowfall, closer truss spacing and heavier steel can provide added structural support. Some American Carports units are certified for 30 pounds per square foot, and higher certifications may be available depending on the project.
Can an RV Carport Handle Heavy Snow?
Yes, a properly engineered RV carport can be designed to handle the snow load required for your site. The key is ordering it for the actual location rather than purchasing a generic model based only on price or approximate size.
When discussing your project, be ready to provide:
- Your installation address or ZIP code
- Whether you need a permit
- Your local wind-speed and snow-load requirements, if available
- The surface where the unit will be installed
- Your RV’s exact height, width, and length
- Whether you want side panels, gables, or full enclosure
- Access considerations for delivery and installation
Do not climb on the roof to remove snow unless a qualified professional has advised you to do so safely. If snow accumulation appears excessive or the building shows unusual deflection, contact a local professional and follow any guidance from your local building department.
What Size RV Carport Works Best?
The best size RV carport depends on your RV class, including slide-outs, mirrors, ladders, roof-mounted air conditioners, awnings, and room to walk around the vehicle. Class A motorhomes are commonly 35 to 45 feet long, 8 to 8.5 feet wide, and 12 to 13.5 feet tall before roof accessories are considered.
For many Class A motorhomes, a structure at least 14 feet high, 14 to 16 feet wide, and 40 to 50 feet long is a practical starting point. An 18-foot width can be particularly useful if you want to access slide-outs or walk comfortably beside the RV.
| RV situation | Practical custom starting point | Why it helps |
| Class A motorhome | 18 x 40 or 20 x 45 | Provides clearance for a large rig and access around it |
| Large Class A with accessories | 18–20 feet wide, 14–16 feet high | Allows room for roof AC units, antennas, mirrors, and slide-outs |
| Class C RV | 14–18 feet wide, 12–16 feet high | Accommodates cab-over height and exterior accessories |
| Travel trailer | 14 x 30 or 14 x 35 | Works as a starting point for many smaller RVs |
| RV plus vehicle or storage | Wider or longer custom layout | Creates usable space for a tow vehicle, golf cart, or equipment |
Measure the highest point of your RV, including every rooftop feature, then add at least two feet of vertical clearance. Add room on each side for mirrors, doors, walking space, and slide-outs. American Carports recommends adding at least two feet of width on each side and a minimum of two feet above the highest point of the RV.
Should You Add Side Panels?
Side panels are often a smart choice for locations with blowing snow, prevailing winds, harsh afternoon sun, or wind-driven rain. A roof-only carport protects the RV from direct precipitation and UV exposure, but it cannot block weather entering from the sides.
A practical high-wind/snow configuration may include one or two panels on the windward side, a gable end, or a partial enclosure. This approach can improve protection without fully enclosing the structure.
However, panels should never be added as an afterthought in a high-wind area. They change the way wind interacts with the building, which is why your selected panel layout should be included in the certified design. For maximum protection, consider a custom building or a fully enclosed metal garage with an RV-height door.
What About Permits and Local Codes?
Permitting requirements vary throughout the United States. Your city, county, state, HOA, or rural planning department may set requirements for setbacks, foundation type, wind rating, snow load, height, drainage, electrical work, and engineered drawings.
This is especially important in areas such as:
- Coastal and hurricane-prone regions, where wind certification and anchoring are major considerations
- Northern and mountain regions, where snow-load certification may determine truss spacing and frame specifications
- Wildfire-prone western areas, where site access, clearance, and local land-use rules may affect placement
- HOA-governed neighborhoods, where roof colors, location, height, and visible side panels may require approval
- Rural properties, where a larger structure may still require a permit or engineered plans
The most reliable approach is to contact your local building authority before ordering. Then share the requirements with us so we can help you customize a structure suited to the project.

FAQs
What is the best roof style for an RV carport in snow?
A vertical A-frame roof is generally the best option because vertical panels help snow, rain, and debris shed from the roof more effectively.
What wind rating should my RV carport have?
Choose the wind rating required by your local building department for your installation address. American Carports, Inc. can engineer structures for specified wind-speed certifications when requested during ordering.
Is a 12-foot-tall carport high enough for a Class A motorhome?
Usually not. Many Class A RVs reach 12 to 13.5 feet before rooftop accessories, so at least 14 feet of clearance is commonly recommended, with 16 feet potentially safer for taller rigs.
Do I need side panels on an RV carport?
Not always, but side panels can help block wind-driven rain, snow, and sun. Include them in the original engineered design, especially in high-wind areas.
Can I use a regular carport for an RV?
Only if it has enough width, length, height, certifications, and anchoring for your specific RV and local climate. RVs typically need substantially more clearance than passenger vehicles.
