What This Service Is

Understanding rv roof repair & sealing for your RV

RV roof repair and sealing is the process of inspecting, repairing, and re-waterproofing the membrane, seams, vents, skylights, and sealant lines that keep your RV's interior dry. At Javi's RV Services Center in Lancaster, we work on TPO and EPDM rubber membranes, fiberglass roofs, and all factory Dicor lap sealant lines that the harsh Antelope Valley sun bakes dry.

Roof leaks are the single most expensive failure an RV owner can ignore. Water that enters through a cracked seam silently rots wood framing, delaminates sidewalls, and ruins interior ceilings long before a visible stain appears. Our shop performs a complete 21-point roof inspection, removes brittle sealant, and applies commercial-grade UV-resistant sealant so your coach stays watertight.

Signs You Need RV Roof Repair & Sealing

If you recognize any of these symptoms, call our Lancaster shop to schedule a diagnostic before the problem worsens.

•A soft or spongy feel when walking on the roof membrane
•Flaking or powdery TPO/EPDM rubber coating in the desert sun

•Your RV is over 5 years old and has never had a professional roof reseal
Our Shop Process

How RV Roof Repair & Sealing Works at Javi's

01

Full 21-Point Roof Inspection

We inspect every seam, vent, skylight, antenna, and membrane edge — both on the roof surface and from inside the coach — to map every leak source before any sealant is applied.

02

Old Sealant Removal

Cracked and brittle factory Dicor and lap sealant is mechanically removed so new sealant bonds to clean substrate, not failing rubber.

03

Membrane Repair & Resurface

Damaged TPO/EPDM sections are patched or re-coated, and gaskets on vents, fans, and rooftop AC units are replaced where they have dried out.

04

Commercial Sealant Application

Commercial-grade UV-resistant lap sealant is applied to every penetration and seam, then the roof is tested to confirm a watertight result before you drive home.

Call for a Written Estimate

Every RV and repair is different, so we quote from a written estimate after inspecting your vehicle — you authorize the scope and cost before any labor begins. Call the Lancaster shop to discuss your RV and the work you need.

RV Roof Repair & Sealing FAQs

Questions RV Owners Ask

Q: How often should an RV roof be resealed?

In the Antelope Valley desert climate, roof sealant should be inspected every 12 months and re-lapped every 3 to 5 years. Intense UV and heat accelerate sealant failure faster than in coastal areas.

Q: Can you repair a roof leak I already see inside the RV?

Yes. We trace the interior stain back to its roof source, repair the failed seam or gasket, and inspect the surrounding membrane for hidden moisture so the leak is fixed at its root — not just covered over.

Q: Do you replace skylights and vent fans during a roof reseal?

Yes. Dried gaskets on skylights, Maxxair fans, and plumbing vents are a common leak source, so we replace gaskets and cracked units as part of a complete roof service.
