Do RV Covers Cause Mold? How to Protect Your Rig the Right Way

11/19/2025

If your RV sits outside at your site at Treeside MHP for part of the year, it’s constantly exposed to sun, rain, humidity, and temperature swings. That’s why many RV owners use a cover—but there’s a big question: do RV covers cause mold? The answer is no, as long as you use a breathable RV cover and prep your rig correctly.

Mold and mildew only form when moisture gets trapped with organic debris and stagnant air, which is exactly what happens under non-breathable plastic tarps. Cheap polyethylene tarps seal in condensation, scratch roofs and decals, and can actually speed up damage to your RV. A high-quality RV cover made from breathable polyester or polypropylene blends is designed to let trapped humidity escape while still blocking rain, UV rays, and dust—making it ideal for long-term RV storage and extended-stay RV living.

To prevent mold on your RV at Treeside RV Park & Campground, always start with a clean, dry roof and sidewalls, remove sharp accessories or pad them with foam or pool noodles, and choose a cover with vented panels, reinforced corners, and a soft inner layer. Install it on a calm, dry day, inspect it monthly, brush off debris after storms, and store the cover dry when you remove it. With the right breathable cover and smart storage habits, you can protect your RV’s roof, seals, graphics, and paint, reduce interior heat, and keep your rig ready for your next stay at Treeside.
