Mobile RV Roof Leak and Sealant Repair in St. Louis

Q: How Do I Know If My RV Roof Is Leaking?

The signs aren’t always obvious—until they are. Look for brown stains or soft spots on the ceiling, bubbling walls, moldy smells, or visible cracks and peeling on the roof seams. After heavy rain, you might notice dripping or pooling water inside light fixtures, vents, or corners.If your RV is more than a few years old or hasn’t been resealed recently, it’s wise to get it checked before things escalate. Our mobile techs will inspect every inch of your roof to spot leaks early, patch them fast, and help you avoid major damage or expensive repairs down the line.

Q: What’s the Best Sealant for an RV Roof?

It depends on your roof material, but in general, EPDM and TPO rubber roofs require non-petroleum sealants like Dicor self-leveling lap sealant or EternaBond tape for long-lasting adhesion and flexibility. For fiberglass roofs, we adjust based on seal structure and expansion behavior.We’ll identify your roof type during our initial inspection and apply the product that delivers the longest-lasting seal and compatibility with your existing material. You don’t need to guess—we bring the knowledge, the sealants, and the skill to do it right the first time.

What We Offer: Roof Leak and Sealant Repair Explained

Our mobile roof repair services are designed to prevent water damage, extend the life of your RV, and protect your trip. Whether you’re dealing with a torn seam, cracked caulking, or a mystery drip from a skylight, we’ll inspect, diagnose, and fix it without moving your RV an inch. We specialize in roof leak repair, roof resealing, vent and skylight resealing, and full roof inspections for all RV types—Class A, B, C, travel trailers, and fifth wheels.

Our process is thorough but efficient. We begin with a complete inspection of your roof’s seams, edges, and fixtures. From there, we clean the area, prep the surface, and apply industry-trusted sealants that bond strong and last long. Most jobs are completed the same day, and we serve the full Greater St. Louis area—including Chesterfield, St. Charles, Belleville, and beyond.

Fast, On-Site Service That Prevents Costly Water Damage

A roof leak might start small, but left untreated, it can cause interior rot, mold, damaged insulation, and thousands in repairs. That’s why we offer same-day or next-day mobile service—you don’t have to wait for a shop appointment or risk worsening damage during travel.

We handle everything from emergency patches to full reseals, with mobile service vans stocked for the most common roof issues. We’ll address peeling edges, cracked sealant, torn rubber, or leaking vent covers with precision. Our job isn’t just to stop the leak—it’s to give you peace of mind and get your RV ready for the road again, fast.

Trusted Materials, Long-Term Protection

We don’t believe in “just good enough.” That’s why STL Mobile RV Repair uses only proven products that RV manufacturers trust—Dicor self-leveling sealant, EternaBond roof tape, Lap Sealant, and more. These materials are selected for durability in tough conditions—rain, sun, freezing temps, and long hauls.

We apply each sealant based on your roof type (EPDM, TPO, or fiberglass) and pay extra attention to high-risk areas: roof edges, vents, skylights, AC units, and seams. If you’ve already tried DIY patches that didn’t hold, we’ll re-do it right. We fix leaks with long-term performance in mind, not temporary cover-ups.
