As winter approaches in the Pacific Northwest, RV owners face the challenge of protecting their vehicles from the region’s notorious rain and occasional snowstorms. Properly winterizing the exterior of your RV is essential to prevent moisture-related damage and keep your vehicle in top shape throughout the season. Here’s how you can safeguard your RV’s exterior from the elements and ensure it’s ready for the road when spring returns.
Clean and Inspect the Roof
The first step in protecting your RV’s exterior from rain and snow is ensuring the roof is clean and free of damage. The Pacific Northwest’s wet climate can cause roof leaks, which, if left untreated, can lead to costly repairs.
- Wash the Roof Thoroughly: Use a mild soap and water solution to clean your RV’s roof and remove dirt, grime, and debris that may have accumulated during the camping season.
- Inspect for Cracks or Leaks: Carefully check all seams, vents, and edges for cracks or worn-out sealant that may allow water to seep into your RV.
- Tip: If you notice any cracks, apply a high-quality RV roof sealant to prevent leaks. Regular maintenance of the roof can prevent long-term damage.
Apply a Protective Wax Coat
Rain and snow can strip the protective layers from your RV’s exterior, leading to oxidation and corrosion over time. Applying a wax coating helps shield the surface from moisture, UV rays, and road debris.
- Wax the Exterior: After washing your RV, apply a coat of wax to the body. Wax creates a water-resistant barrier that helps keep the surface of your RV dry and protected from the elements.
- Tip: Use an RV-specific wax that’s designed for fiberglass or aluminum exteriors, depending on your RV’s material. A good wax job will make it easier to clean your RV after winter storage.
Check Seals and Seams
Any tiny gaps or damaged seals around your RV’s windows, doors, or vents can allow rain to penetrate your RV’s interior, leading to moisture damage and mold growth.
- Inspect All Seams: Pay special attention to the seals around windows, doors, and roof vents. Look for any signs of cracking, peeling, or worn-out caulking.
- Reseal as Needed: Apply fresh sealant to any damaged or aging seals. Products like Dicor lap sealant or Eternabond tape are great for quick, long-lasting fixes.
- Tip: Don’t forget to check the seams at the corners of your RV and along any slide-outs. Water can easily find its way into even the smallest cracks.
Use a Breathable RV Cover
One of the most effective ways to protect your RV from rain and snow is by using a high-quality, breathable RV cover. A good cover will shield your RV from moisture while still allowing trapped condensation to escape, preventing mold and mildew from developing.
- Invest in a Quality Cover: Make sure to choose a cover that is waterproof yet breathable. Look for covers designed for winter use, and make sure it’s the right size for your RV to avoid flapping in the wind.
- Secure the Cover: Properly secure the cover with straps or ties to prevent it from shifting in the wind and causing scratches to the exterior.
- Tip: Avoid using tarps or plastic covers, as they can trap moisture and lead to mildew or mold growth.
Prevent Tire and Undercarriage Damage
Tires and the undercarriage of your RV are particularly vulnerable during the winter months. Rain, ice, and road salt can damage the undercarriage, while standing snow can lead to flat spots on tires if the RV is stationary for extended periods.
- Use Tire Covers: Protect your tires from UV rays, moisture, and extreme cold by using tire covers. This helps prevent cracking and flat spots that can occur when tires sit unused in freezing temperatures.
- Elevate or Rotate the Tires: If possible, use jack stands to slightly elevate your RV or periodically rotate the tires to avoid long-term flat spots.
- Tip: Consider applying an undercarriage protectant to prevent rust and corrosion caused by moisture or road salt exposure.
Final Inspection: Secure Everything
Before covering your RV or putting it into storage, take the time to do a final inspection of all exterior components.
- Check for Loose Parts: Ensure that all antennas, awnings, and other external accessories are properly secured or retracted. Loose parts can become damaged or cause damage during winter storms.
- Secure Slide-Outs: Make sure any slide-outs are fully retracted and sealed to prevent water from entering through the edges.
- Tip: If your RV has an exterior water heater, consider adding an insulated water heater cover to protect it from freezing temperatures.
Protect Your RV’s Exterior This Winter
The wet winters of the Pacific Northwest demand that RV owners take extra precautions to protect their vehicles from moisture and cold. By following these essential steps, you can ensure your RV’s exterior remains in excellent condition, ready for your next adventure when spring arrives.
