San Diego RV Center is one of the few Rhino-certified RV shops in San Diego applying Rhino EcoCoat RV roof coating. If your motorhome’s EPDM roof is showing early signs of deterioration — chalking, small cracks, or surface checking — but doesn’t yet need a full replacement, Rhino EcoCoat is worth understanding. It’s a spray-applied protective membrane that bonds directly to the existing roof surface, extends its service life by 10 years or more, and costs significantly less than a full reskin.

What Is Rhino EcoCoat?

Rhino EcoCoat is a spray-applied polyurea coating — the same technology behind Rhino truck bed liners — adapted for RV roofs. When sprayed onto a prepared roof surface, it bonds chemically and cures into a thick, flexible, waterproof membrane with no seams. Unlike rolled rubber or lap sealant repairs, there’s nowhere for water to find an edge.

The material is UV-resistant, handles thermal expansion and contraction well (important in Southern California’s heat), and doesn’t crack or peel the way some painted-on coatings do over time. Once cured, the surface needs only basic cleaning to maintain it. This is not a paint or a rubberized coating from a hardware store — it’s an industrial membrane applied by certified technicians.

Why Certification Matters

Rhino EcoCoat is only available through Rhino-certified applicators. The certification covers surface preparation, application technique, and thickness — all of which directly affect how well the coating adheres and how long it lasts. A coating applied over inadequately prepared or contaminated surfaces won’t bond correctly and will fail early.

San Diego RV Center is Rhino-certified specifically for RV roof applications. That’s different from a general Rhino truck bed liner shop. The roof geometry of an RV — with vents, air conditioner bases, antenna mounts, and seams — requires specific experience to coat properly without leaving gaps or thin spots at the penetrations.

Best Candidates for Rhino EcoCoat

Rhino EcoCoat works best on EPDM rubber roofs that are intact but showing early wear. Signs that a roof is a good candidate include surface oxidation, minor cracking or checking, and lap seams that are starting to lift but haven’t allowed water into the substrate. The key requirement is that the roof structure underneath — the decking and substrate — must still be sound.

If the roof has already been leaking for some time and the substrate is soft, wet, or delaminated, coating over it won’t work. In those cases, the right answer is a partial or full roof replacement. We assess the roof condition honestly before recommending EcoCoat — if it needs a replacement, we’ll say so. You can see what a full replacement involves on our RV roof replacement page.

How Rhino EcoCoat Compares to Roof Replacement

A full EPDM roof replacement on a Class A motorhome is a significant job. The old membrane comes off, any damaged decking or substrate gets repaired, and a new membrane goes down with all new sealants at every penetration. It’s the right call when the existing roof is too far gone to save.

Rhino EcoCoat is the right call when the existing roof is still structurally sound but showing surface deterioration. It costs substantially less than replacement, takes less shop time, and delivers a surface that will outlast multiple rounds of lap sealant touch-ups. For roofs in the middle ground — past their best but not failed — it’s a practical, cost-effective option. Our RV roof repair services cover everything from spot repairs to this type of coating application.

The Application Process at Our Shop

Before the coating is applied, the roof is thoroughly cleaned and decontaminated. All penetrations — vents, AC units, antennas — are carefully masked or prepped. The Rhino EcoCoat is then spray-applied in a controlled pass to achieve the correct, even thickness across the entire surface. The coating is inspected before the rig leaves the shop.

The process typically takes one to two days depending on the size of the rig and the condition of the existing roof surface. We’ll walk you through what to expect when you bring it in. For context on what we handle across all roof work, our RV motorhome maintenance and roof services pages cover the full range of what we do.

Serving San Diego County RV Owners

Our shop is at 9398 Bond Avenue in El Cajon, CA 92021, serving motorhome owners from across San Diego County — Santee, La Mesa, Lakeside, El Cajon, and the broader San Diego area. We’ve been at this location since 1990, so we know the local climate and what it does to RV roofs parked outdoors in the sun.

Southern California heat accelerates EPDM oxidation faster than owners in cooler climates expect. If your rig sits outside year-round and the roof hasn’t been inspected in the last two to three years, it’s worth having us take a look. Check our service areas page to see the full list of communities we serve, and visit why choose San Diego RV Center for more on how we approach every job.

Frequently Asked Questions

How long does Rhino EcoCoat last on an RV roof?

Rhino EcoCoat is expected to last 10 years or more with proper maintenance — which is primarily keeping the roof clean and inspecting it annually. The actual service life depends on how well the surface was prepared before application and how the rig is stored. Rigs parked under cover will see longer life than those parked in direct sun year-round.

Can Rhino EcoCoat be applied over an existing rubber roof that has lap sealant on it?

In most cases, existing sealant needs to be cleaned or removed from lap seams before application to ensure proper adhesion. During our surface prep, we assess what’s on the roof and determine the right approach. This is part of the certified application process — skipping prep steps is what causes coatings to fail.

Is Rhino EcoCoat available for fiberglass or TPO roofs?

The primary application we recommend is for EPDM rubber roofs. Other roof substrates may require different products or processes. When you bring your rig in for a roof assessment, we’ll identify the roof type and recommend the right approach — whether that’s EcoCoat, a spot repair, or a full replacement.

What if my roof needs repairs before the coating can be applied?

If the roof has localized damage — a puncture, a failed seam, or a soft spot — those areas typically need to be addressed before the coating goes on. We handle both the repair work and the coating application, so it’s a single shop visit. See our RV roof repairs page for more on what spot repairs involve, or visit our RV repair FAQs for general questions about our process.
