San Diego RV Center has been repairing RV roofs in the county since 1990, and the first question on every owner’s mind before any job starts is the same: what is this going to cost me? RV roof repair cost in San Diego typically runs from $300 for a basic reseal to more than $8,000 for a full replacement on a large Class A motorhome. What you pay depends on your roof type, damage severity, and how long the problem has been left unaddressed. The numbers below come from real jobs done at our El Cajon shop.
What Drives RV Roof Repair Cost
Three variables push your estimate up or down more than anything else. The size of your rig matters most — a 40-foot motorhome has roughly twice the roof surface of a 22-foot travel trailer, and materials and labor scale with every square foot. Your roof material is next: rubber EPDM, TPO membrane, and fiberglass each carry different repair costs and methods. Finally, how long the damage has been present changes everything. A crack caught early costs a fraction of what it costs after moisture has had six months to work into the decking and interior walls.
Cost Breakdown by Repair Type
Here is what owners in the San Diego area should expect to pay for common RV roof repairs in 2026:
- Reseal only (seams, vents, AC boots): $300–$700. Standard preventive work that stops leaks before they start.
- Small patch repair (under 2 sq. ft.): $400–$900, depending on roof type and location.
- Rhino roof coating (full application): $1,200–$2,500 on a mid-size unit. Eliminates routine resealing for 10 or more years.
- Section replacement (one-quarter to one-half of the roof): $1,800–$4,000.
- Full roof replacement: $3,500–$8,500 or more, depending on rig size and material.
These ranges reflect current San Diego labor rates and material costs. Any quote significantly below these numbers is worth questioning — find out what is being skipped before you sign anything.
How Roof Material Changes the Price
EPDM rubber is the most common material on production RVs and the least expensive to repair. Patches bond reliably and the membrane itself is affordable relative to alternatives. TPO costs more upfront but holds up better against UV exposure — a real advantage on an RV parked in Southern California sun year-round. Fiberglass is the premium option: rigid, durable, and the most labor-intensive to repair when it cracks. Not sure what your roof is made of? EPDM is matte rubber, usually white or gray. TPO is a smoother bright white. Fiberglass is rigid with a slight gloss.
Full Roof Replacement vs. Repair: Which Cost Makes More Sense
This is where owners most often make an expensive mistake. Patching a roof that has degraded past a certain point produces a repair that fails within a season — and then you pay for both the patch and the replacement. Experienced technicians use a 25 percent threshold: if more than a quarter of your roof surface is compromised, full replacement almost always costs less over three years than a series of partial fixes. When moisture has reached the decking, costs multiply fast. For a closer look at how repair methods differ by material, see our guide on RV roof repair by material type.

When Interior Damage Raises the Final Bill
A leak that went undetected for months can saturate interior walls, cabinetry, and floor substrate — and repairing that secondary water damage adds $1,000–$5,000 on top of the roof cost itself. California RV insurance policies vary: sudden accidental damage is generally covered, while gradual wear or deferred maintenance is typically excluded. At San Diego RV Center, we document all damage with photos and provide written estimates that work with most major insurance carriers. A call to your insurer before authorizing major repairs is worth the 15 minutes.
What Rhino Roof Coating Costs — and Why It Pays Off
San Diego RV Center is Rhino-certified, and a Rhino roof coating is one of the best-value services we offer for owners keeping their rig five or more years. The application runs $1,200–$2,500 depending on roof size and eliminates routine resealing for a decade or longer. A properly applied coating bonds directly to EPDM, TPO, or fiberglass and blocks the UV degradation that drives premature membrane aging on RVs stored in Southern California. The RV Industry Association identifies water intrusion as the leading cause of major structural repair costs on aging rigs — a coating that stops that process for 10-plus years pays for itself.

How to Get an Estimate You Can Actually Trust
A quote over the phone is not a real estimate. Any number given without a physical inspection of the roof surface, seams, penetrations, and decking is a guess — and guesses on roof work swing $2,000 or more once the actual scope becomes clear. A reputable shop gets eyes on the roof, probes for soft spots, checks every vent boot, and provides a written breakdown before any work begins. At San Diego RV Center, free on-site roof inspections are standard — you get real numbers before committing to anything.

Frequently Asked Questions About RV Roof Repair Cost in San Diego
How long does RV roof repair take at a San Diego shop?
Reseal and small patch jobs are typically done same-day or within 24 hours. Partial section replacements run 2–3 days. A full roof replacement on a large Class A motorhome takes 4–7 business days, depending on material lead times and the number of roof fixtures that need removal and reinstallation.
Is RV roof damage covered by insurance in California?
It depends on the cause. Sudden damage from a storm, falling object, or collision is generally covered under a comprehensive RV policy. Gradual wear and deferred maintenance are typically excluded. Document damage with dated photos immediately and call your carrier before authorizing major repairs — pre-authorization is required by many California policies above a certain cost threshold.
Is Rhino roof coating worth the upfront cost?
For owners keeping their RV five or more years, the math is clear. At $1,200–$2,500 for a full application, Rhino coating eliminates annual resealing and extends membrane life by a decade or more — pushing a $4,000–$7,000 full replacement 10-plus years down the road.
Does rig size significantly affect the repair price?
Yes. A 40-foot Class A can have 400 square feet of roof surface. A 22-foot travel trailer has roughly half that. Most roof services are priced per square foot for materials and scale with total area for labor — though minimum job costs apply regardless of rig size.
