When putting your RV away for the winter or parking it between trips, the same question comes up: should you cover your RV? Sun, rain, snow, and ice can cause lasting damage to your roof, seals, and finish whenever your RV sits outdoors, but some experienced owners complain that a cover requires effort to install, wears out over time, and isn’t the right call for every RV or storage spot.

Below, we’ll cover when a cover makes sense, why winter matters most, how covers protect your rig, their honest downsides, and the alternatives.

Disclaimer: Getting on an RV roof or using a ladder is done at your own risk. Roofs can be slick, uneven, or structurally weak, and a fall can cause serious injury. Use proper fall protection, a stable ladder on level ground, and never work alone or in wet or windy conditions. If you are uncomfortable with heights, have mobility limits, or suspect soft decking, stay off the roof and hire a qualified technician. 

When Should You Cover Your RV?

Any time your RV will sit outdoors for more than a few weeks, whatever the season. A breathable, RV-specific cover protects the roof, seals, and finish from UV, rain, snow, and debris while your RV is in storage. Winter is when a cover arguably matters most, but summer sun and heat take a toll, too.

Uncovered, UV rays beat down on your RV, causing heat to build up on the surface. This can damage paint, decals, seals, and other exterior fixtures. Furthermore, this heat can raise interior temperatures to dangerous levels, damaging decor, appliances, and other components.

Conversely, snow, sleet, and rain can leave an unprotected RV vulnerable to leaks. If heavy snow accumulates on your RV and then melts, water can pool and stress your RV’s structure. If left unattended, the damage can require a complete roof repair. 

Our guide to RV roof repair and replacement costs shows how quickly that bill can climb.

Left exposed, an RV’s paint, graphics, and trim will fade, crack, and deteriorate. Dirt and debris collect on your roof, leaving black streaks when rain falls.

Should You Cover Your RV in Winter?

Yes, and winter is arguably when a cover does the most good. Freeze-thaw cycles work at the sealant around seams and vents, and melting snow and ice causes water to pool wherever the roof dips.

For most experienced owners who store their campers outdoors, covering is the last step of winter storage — after winterizing your RV plumbing, closing the roof vents, and washing and drying the exterior to prevent dirt and moisture from being trapped under the fabric. 

Our guide to installing an RV cover covers the rest of the prep.

What If There’s Already Snow on Your RV?

Clear it first. Never put a cover on over snow or ice. Use a soft telescoping roof rake or broom and, ideally, wait for a dry day. Working from a ladder is generally safer than standing on a slick RV roof, but caution is still warranted. Once the cover is on, brush off heavy snow after big storms with the same soft tools. Skip the metal shovel, and keep snowblowers well away. As a teenager, I burned holes in my parents’ RV cover by pushing the snowblower too close to it. That exhaust is hot, and Dad wasn’t happy!

Does a Cover Add Snow Weight to Your Roof?

The cover itself adds very little weight. The load comes from wet snow that settles on top of it, especially where the fabric drapes over the air conditioner shroud and roof vents. Check your owner’s manual for roof load guidance, and clear accumulated snow after heavy storms rather than letting it build.

Check Under the Cover Once a Month

A covered RV is harder to inspect, so a small leak can go unnoticed until spring. Once a month, on a dry day, loosen a section of the cover and inspect the roof seams, vents, and slide-out seals. Catching cracked sealant in January is far cheaper than finding water damage in April.

How Does a Cover Protect Your RV?

A breathable RV cover takes the brunt of the weather while your RV sits. Here’s what it does:

• Blocks UV rays. The top layer deflects direct sunlight, so paint, decals, and roof sealant don’t bake, and interior temperatures stay lower. Putting on an RV cover before long stretches in the sun is one of the easiest ways to prevent fading.

• Sheds rain and snow without trapping moisture. A water-resistant top layer keeps precipitation off the roof and seams, while breathable fabric lets condensation escape.

• Shields against wind-blown debris. Leaves, pine cones, and pollen land on the cover instead of scratching or staining your RV.

• Keeps dirt and droppings off. You’ll spend less time washing your RV, waxing, and treating the roof, and your RV spring cleaning goes faster.

• Protects resale value. A roof, finish, and seals that stay in good shape keep your RV worth more when it’s time to sell or trade.

What Are the Disadvantages of RV Covers?

RV covers aren’t perfect, though. Here are the downsides to weigh:

• Takes work to install. On a tall travel trailer, fifth wheel, or motorhome, it’s usually a two-person, two-ladder job, though it gets easier with practice.

• Can tear in high winds. A loose cover billows and strains its straps, so tighten them snugly and re-tighten them before high winds are forecast. Where strong wind is the norm, covered storage may be the better investment.

• Can scuff the finish. A loose cover over a dirty RV acts like sandpaper on fiberglass and decals, so wash and dry your RV first, pad sharp edges, and keep the straps snug.

• Can hide problems. You can’t see a roof leak developing under a cover, which is why the monthly check above matters.

• Wears out over time. UV exposure gradually breaks down the fabric, so plan on replacing yours eventually (see the FAQ below).

• Limits how you use your RV. Never sleep in a fully covered RV or run its propane appliances, because the vents are blocked, and solar panels won’t charge under a cover.

Which Storage Situations Call for an RV Cover?

Whether you need a cover depends mostly on where you store your RV and how often you use it:

Your storage situation	Cover?	Why
Outdoors in snow country	Yes	Snow, ice, and freeze-thaw cycles are hardest on roofs and seams; a roof-only cover works if you need access
Outdoors in hot, sunny climates	Yes	Constant UV and heat fade the finish and dry out sealant
Outdoors anywhere, unused for more than a few weeks	Yes	Long, unattended storage is when damage adds up unnoticed
High-wind site with no shelter	Depends	Only if you can keep the cover tight; otherwise, look for covered storage
Covered storage, carport, or open-sided roof	Optional	The roof is protected, but the sides still get sun and blowing debris
Indoors or in a fully enclosed building	Usually no	The building does the job; a breathable dust cover is optional

RV Cover Alternatives: Tarps, Roof-Only Covers, and Covered Storage

Here’s how the most common alternatives compare. One is a bad idea; the others make sense in the right situation.

Plastic Tarps

Some owners ask, “Can you use a tarp instead of an RV cover?” No. A plastic tarp isn’t a good substitute for an RV cover. Tarps don’t breathe, so condensation gets trapped against your roof and sidewalls, creating a breeding ground for mold and mildew.

Tarps are also hard to secure. They billow and flap in the wind, scuffing gelcoat and decals and straining the bungee cords and ropes holding them down. Cords stretched over sharp edges can tear the tarp or snap back against your RV.

If budget is the concern, a breathable cover sized for your RV type is still the safer choice, and covered storage avoids the question entirely. 

Roof-Only RV Covers

A roof-only cover, sometimes called an RV roof canopy, is a fitted fabric panel that covers just the top of your RV. It straps to the RV itself, so it travels with you, unlike a carport, which is a freestanding structure built over your parking spot. Because the sides, windows, and door stay uncovered, you can still get inside without removing it.

Roof-only covers come in two main styles:

• Shade canopies use a mesh fabric that blocks sun and heat but isn’t fully waterproof. They’re designed to stay on while you camp, so they’re popular in hot climates, where a shaded roof helps your air conditioner keep up.
• Solid roof covers use breathable cover fabric that sheds rain and snow, which makes them a better fit for storage in wet or snowy climates.

Either way, the trade-off is the same: sidewalls, decals, and windows remain exposed, so a full cover still offers greater protection. Look for one that straps down securely; covers that only hook along the roof edge can shift in high winds.

Technician Tip: A full RV cover doesn’t fully protect your tires, so if yours doesn’t include a set, buy RV tire covers separately.

Covered or Indoor Storage

Indoor storage offers the most protection, and covered storage or a carport keeps snow and sun off the roof, though the sides stay exposed. If you have access to either, you may not need a cover at all (see the table above).

What to Look for in an RV Cover

Not all RV covers perform equally. For protection, the features that matter most are breathable fabric, vents that reduce billowing, tension straps or a cinching system for a snug fit, and the right size for your RV. The diagram below shows the main parts of a typical ADCO-style cover.

Is an RV Cover Worth It?

Many new campers shy away from buying an RV cover because of its cost. Covers typically run from about $120 for a pop up camper to around $600 for a Class A motorhome, depending on size and material. However, that often pales in comparison to the costs of repairing roof damage, replacing vents, installing a new air conditioner shroud, and other potential damage that comes with improper RV storage.

Beyond paying for covered RV storage, using a fabric RV cover is the best way to protect your recreational vehicle investment. It’s also much more affordable to replace a worn cover than it would be to replace an entire RV roof. So, for most campers stored outdoors, a cover is worth it.
