Why consider using an RV Cover

David Pollard • August 9, 2021

 There is a healthy debate online over the pros and cons of using an RV cover. That said, we noticed many of the poor experiences were due to poor quality cover choices or not using the proper cover for the climate the RV must weather. Proper fit and function are critical elements to protect your RV, as you would expect.


We hear some of the cons related to moisture build-up, chaffing damage to the exterior finish, the cumbersome size to install or remove, and then there is the price. Other than the install, the other cons mentioned can be addressed with choosing the right cover for your specific RV.


Some of the pros are protection from expensive repair costs caused by UV damage, failed waterproofing seals, protects resale values and covers cost less than paying for inside or covered storage.  


Unless you have inside winter storage or a large roof cover to store your RV during the winter, chances are it is sitting outside. When exposed to the elements, all of that sitting can do a lot of harm over time. There is a straightforward way to protect your investment—use an RV cover.

Choose The Right Cover

First, this is very important: we’re not talking about wrapping your RV with any old covering. You’ll find lots of campers using the infamous blue tarp in driveways and at storage yards across the country. While this will do in a pinch for the short term, these tarps aren’t made specifically to cover RVs. You are getting some protection but can experience all the cons outlined earlier. Blue, brown, clear tarps should never be used as a longer solution.


You want a cover that’s designed for your rig and 4-seasons for winter protection. These covers are made to fit your rig so you can be sure it’s sized appropriately. Look for one that will fit snugly, with reinforced corners and gutter protectors to help prevent tears or frays.


Here are a few things RV-specific covers will guard against:

  • Ultraviolet Light

It’s hard to argue that a beautiful, sunny winter day. But when your RV is sitting in storage, the sun’s UV rays are fading its colours, drying out its paint, cracking the roof seals, and doing damage to the entire rig.


Find a cover made of a material that will block UV rays. Any covers made light in colour to reduce temperature build-up, and from polyester or polypropylene —especially if it’s double or triple-layered. Many are treated specifically to provide extra UV protection.


  • Moisture

Water is one of an RV’s enemies, specifically when it’s trapped under a tarp or poor cover. If condensation collects below the cover and can’t escape, it provides a breeding ground for mold and mildew. In more extreme temperatures, it can lead to freezing and cracking around the roof.


The best RV covers will be waterproof yet breathable. Small pores in the fabric allow moisture to evaporate without allowing water droplets in. 


  • Wind

Windy conditions can catch tarps or poorly chosen covers and cause them to billow out. This causes strain on straps, bungee cords, or ropes that might be holding it in place or cause them to smack against your RV.


Covers with patented vent flaps help reduce billowing, while elastic can help hold the cover tight against the RV. This way, you are getting maximum protection from the elements with little risk of your cover getting loose and ending up at the other end of the storage yard.


  • Snow & Ice Protection – 4 Season Cover 

Less expensive covers will NOT be a 4-season rated cover. Some less expensive covers are only designed to protect UV, wind, and sand for southern USA climates. 

Outdoor storage during Canadian winters requires a true 4-season cover. Some provinces are seeing more dramatic winter weather shifts from heavy snowfall one day to freezing rain the next with considerable ice buildup. This freeze, thaw cycle for RV’s stored outside enlarge small sealant failures into becoming big ones, while you cannot inspect your RV for several months.

When rain starts sneaking through your roof seams or a skylight gasket lets go, the goal is simple: stop the water now and protect the interior until a mobile repair technician can take over. The steps below are road‑tested, safe, and meant to buy you time without creating a bigger mess for later. Think of this as a first‑aid kit for your RV’s seals. First, stay safe Water and height are a risky pairing. Before anything else: Park on level ground, set the brake, and wait out lightning or high winds. Turn off 120V power at the breaker if water is near outlets or fixtures. Use a stable ladder with a spotter. Shoes with a good grip beat flip‑flops every time. If conditions aren’t safe, pause and call mobile repair right away. Fast triage: find the source Leaks can travel along framing and show up far from the entry point. Start at the top and work down: Usual suspects: roof vents, skylights, AC shrouds, antenna mounts, front/rear cap seams, and ladder or rack penetrations. Edges and corners: perimeter mouldings and gutter rails often hide hairline gaps. Slide‑outs: torn wipers or flattened bulb seals let water wick inside. Windows & marker lights: failed butyl behind the flange; don’t confuse this with condensation. Wipe suspected areas dry with a microfibre cloth and watch for fresh trails. If you can’t pinpoint it quickly, stabilize the area with a tarp (details below) and book mobile repair. Your roadside leak kit (pack it now) Microfibre cloths and paper towels Isopropyl alcohol (70–99%) for surface prep Plastic scraper and utility knife Butyl tape (for flanges) RV roof repair tape (micro‑sealant tape) Non‑sag sealant for vertical seams; self‑levelling for horizontal laps Clear plastic sheeting and painter’s tape Soft roller for tape activation Nitrile gloves and safety glasses Small tarp, paracord or ratchet straps, and a pool noodle or foam ridge Temporary fixes that hold (without causing new problems) General rules: Clean, dry, then patch. Alcohol wipe → dry → apply. Warm products stick better; keep tapes/caulks inside the coach until use. Avoid silicone on EPDM—it rarely bonds well and complicates the permanent fix. EPDM or TPO rubber roofs Small seam or pinhole: bridge with roof repair tape, extending at least 50 mm (2") past the damage on all sides. Roll firmly to activate the adhesive. Cracked lap sealant at a vent: scrape loose debris, wipe, then add self‑levelling sealant around the flange. If rain is active, tape first and seal later. Fibreglass or aluminum roofs Hairline crack: Clean, dry, and apply repair tape. To avoid wrinkles, make relief cuts in the tape for curved corners. Loose trim screws: back out, add a tiny piece of butyl under the screw head, and snug (don’t strip). Cap with a dab of non‑sag sealant. Skylights and roof vents Leaking flange: wrap the perimeter with repair tape, pressing down onto both the flange and the roof membrane. Cracked lid: lay plastic sheeting over the lid and tape it to the housing as a rain bonnet. Replace the lid at the next stop. Slide‑outs Torn wiper seal: Retract the slide if safe, and add a temporary “gasket” by taping a strip of plastic across the top edge. Flattened bulb seal: A length of foam backer or even a pool noodle pressed against the side and taped can reduce water ingress until mobile repair can fit a new seal. Windows and marker lights Top‑edge weep: run painter’s tape as a small “drip cap” over the frame to shed water. Important: never block factory weep holes at the bottom of window frames. Tarping the right way (so it doesn’t pool or flap) A sloppy tarp can cause more damage than a shower. For short drives or overnight: Create a ridge with a pool noodle or soft foam down the centre to shed water. Anchor cords to frame points or wheels— not to awning arms or gutters. Pad sharp edges with cloth to protect the roof membrane. Keep the tarp tight; loose fabric will flap and scuff the roof. Dry the inside and prevent mould. Catch drips in pans; swap towels often. If you have shore power, run a small fan and a dehumidifier. Open cabinet doors near the leak to help air circulate. Wipe down wet wood trim quickly; standing water leaves stains and invites mould. When to stop and call a mobile repair technician immediately A tear larger than your hand Bulging or sagging ceiling panels Water near electrical panels, flickering lights, or a burning smell Storm conditions that make roof access risky At this point, containment (tarp and towels) is the smartest move. Book mobile repair and document everything. Document for a smooth hand‑off Take photos of the leak path, the roof area, and each temporary patch. Note the products used and the time you applied them. Keep any loose parts (old screws, cracked lids) in a labelled bag. This record helps the mobile repair technician plan materials and speeds up the permanent fix. What your tech will likely do next Expect a moisture survey with a meter, a controlled removal of temporary patches, proper surface prep, and compatible sealant or tape systems matched to your roof type. If hidden damage is found, they’ll propose a step‑by‑step repair plan so you’re not guessing. Need help now? If you’re on the shoulder with water finding its way in, patch what you can and reach out. RV Pro Seal offers on‑site, professional mobile repair for roof and leak issues—fast, friendly, and done right. We’ll get you watertight and back on the road with clear after‑care instructions.

Have you ever considered your RV more than just a vehicle? For many of us, it is a mobile home, an adventure base, and a significant investment. Like any valuable asset, your RV needs consistent care to stay in top shape and serve you for years. Regular RV resealing services are one of the most overlooked yet absolutely critical aspects of RV maintenance. This simple process can dramatically extend your RV's lifespan and save you from major headaches. The Unseen Threat: Why RVs are Vulnerable to Leaks Imagine your RV cruising down the highway, basking in the sun, or weathering a rainstorm. All these conditions put stress on its exterior. Temperature changes cause materials to expand and contract, road vibrations challenge every seam, and even seemingly harmless sun exposure can degrade sealants over time. These factors create tiny openings, almost invisible to the naked eye, where water can start its insidious journey into your RV's structure. So, what happens when water gets in? Structural Damage: Water can rot wooden frames, delaminate walls, and corrode metal components, weakening your RV's integrity from the inside out. Mold and Mildew: A damp environment is a perfect breeding ground for mold and mildew. These not only create unpleasant odours, but they can also pose serious health risks. Electrical Problems: Water and electronics do not mix. Leaks can short-circuit wiring, leading to costly repairs and potential safety hazards. Reduced Resale Value: A water-damaged RV will fetch a much lower price when it comes time to sell. No one wants to buy a rig with hidden issues. This is why proactive care, like consistent resealing and swift RV water leak repair , is not just about comfort; it is about preserving the very foundation of your investment. The Power of Prevention: How Sealing Maintenance Keeps Your RV Healthy Regular sealing maintenance acts as a robust shield, guarding your RV against the elements. Properly applied sealants create a watertight barrier over every seam, joint, and penetration on your RV's exterior – from the roof and windows to the cargo doors and vents. When you invest in professional waterproofing maintenance, you are not just getting a quick fix. You are ensuring: Long-Term Protection: High-quality sealants are designed to withstand UV rays, extreme temperatures, and vibrations, offering durable protection for years. Early Detection: During a resealing service, technicians meticulously inspect every inch of your RV, often catching potential issues before they become major leaks. This attention to detail is crucial for effective RV water leak repair . Expert Application: To use sealants properly, you need to know how to do it and have the right tools. Experts make sure there is good bonding and a smooth, even seal that really keeps water out. Tips for Keeping Your RV Leak-Free Want to be proactive about protecting your RV? Here are a few straightforward tips: Bi-Annual Seal and Sealant Inspections: Get up on a ladder a few times a year and visually inspect all seams and sealants on your roof and sidewalls. Look for cracks, shrinking, or areas where the sealant has pulled away. Feel for Soft Spots: Gently press on the walls, roofs and ceiling, especially near windows, vents, and lights. Any soft or spongy areas could indicate water damage. Address Issues Immediately: If you spot a problem, do not wait! Even a small drip can quickly escalate. Prompt RV water leak repair can save you thousands in the long run. Professional Check-ups: Consider having your RV professionally inspected and resealed every 2-5 years, depending on usage and climate. This is especially important if you are not comfortable doing the inspections yourself. By committing to regular resealing and partnering with a trusted RV leak testing company in Oakville , you are not just performing maintenance; you are making a wise decision that protects your significant investment. You are ensuring more enjoyable trips, fewer headaches, and a higher resale value when the time comes. Are you ready to give your RV the long, healthy life it deserves?
