RV Roof Repair & Resealing in Sebring, Florida

Florida weather kills RV roofs from both sides: sun cooks the top of the lap sealant around every vent, skylight, antenna, and seam, and weeks of wet air get under its edges and lift it. Then the summer rains, more than half of Sebring’s 52 inches a year falling June through September, find every gap. We repair that at your site anywhere in Sebring and Highlands County: dig out the failed sealant, clean the surface, and reseal, typically $500 to $1,200 for a full reseal. The trip fee is $75 to $150 and diagnosis comes first, like everything we do.

Why inland Florida is a special case for RV roofs

Your roof is not one sheet of material. It is a membrane (EPDM rubber, TPO, or fiberglass) interrupted by a dozen or more penetrations: vents, skylights, the AC unit, the fridge vent, antennas, plumbing stacks, solar entries. Every one of those is sealed with lap sealant, a flexible bead that is supposed to move with the roof. The membrane usually outlives everything; the sealant is the weak point.

In Sebring, that sealant lives a wet life. The muggy season runs from roughly April 25 to November 16, July averages 79 percent relative humidity, and July has measurable rain on about 22 days. A bead of sealant that never fully dries grows mildew and algae along its edge, the edge lifts, and capillary action pulls water under it. Add a July average high above 91°F on a dark roof and the top of the bead chalks and cracks while the bottom is rotting loose. A sealant job that lasts six or seven years in a dry climate is lifting in three here.

Then the water gets in and does not announce itself. It follows the lifted edge into the seam, soaks into the plywood or OSB decking under the membrane, and starts rot in the dark. By the time a brown stain blooms on the ceiling, the water has been in there for weeks. This is the single most expensive preventable failure in RV ownership, and in a climate where the roof is wet from June to September, the timeline is compressed.

First, make sure it is the roof

A surprising share of “roof leak” calls in Highlands County are not the roof. Two things mimic it:

• A clogged AC condensate pan. The rooftop unit is a dehumidifier as much as a cooler here, and the water it pulls out of the air has to leave through the pan and drains. Algae clogs them, the pan overflows, and water comes through the ceiling assembly right below the unit, usually onto the bed. See AC dripping water inside.
• A compressed AC gasket. The unit seals to the roof with a foam gasket, not sealant. It takes a set over the years and the same ceiling stain appears.

We check both before a tube of sealant gets opened, because a $200 to $400 pan cleaning is the wrong thing to turn into a $900 reseal.

What a proper reseal involves

There is a right way to do this, and a fast way that fails within a year. The right way:

1. Full roof inspection. Every penetration, every seam, the membrane itself, and the condition of the decking underfoot. Photographed, because most owners cannot or should not climb up to look.
2. Dig out the failed sealant. This is the step the cheap jobs skip. Lifted, chalky, mildewed sealant comes out. New sealant applied over failing sealant is a fresh layer on a rotten foundation and it will not bond.
3. Clean and prep. Mildew, residue, and oxidation off the work area so the new material actually bonds to the membrane and the fixture, not to grime. In this climate, the cleaning step matters more than anywhere.
4. Reseal with the right product. Self-leveling lap sealant on horizontal surfaces, non-sag formulations on vertical ones, matched to your membrane type: EPDM, TPO, and fiberglass do not all take the same products.
5. Cure window. Fresh sealant needs roughly 48 dry hours to cure properly. This is exactly why April and May are the Florida reseal season: reliably dry days, before the rains arrive to test the work. A reseal in July is a gamble against the afternoon radar.

A typical full reseal lands $500 to $1,200 depending on roof length and how many penetrations it carries. Spot repairs on one or two failed points cost less; we will tell you honestly if that is all you need.

When it is beyond a reseal

If water has already been inside (soft spots underfoot, staining inside, a spongy feel around a vent) the job changes. Wood-rot repair and membrane replacement run $2,000 to $3,000+ and sometimes more, depending on how far the water traveled. We diagnose that honestly and show you the photos before quoting, because the difference between “reseal now” and “rebuild the decking” is exactly the kind of thing you should see with your own eyes.

Storm damage is its own case. Highlands County took hurricane-force gusts from Ian in September 2022 and was the second-hardest-hit county in the state from Irma in 2017. Wind-driven debris on a roof, a torn membrane, or a vent cover that is simply gone after a storm is an insurance conversation, and we document it with photos and a written scope for your adjuster.

The math is lopsided and worth saying plainly: a $700 reseal in April routinely prevents a $3,000 repair in September.

Resort rigs and stored rigs both need this

Roof failure does not care whether the rig is occupied. On the US 27 resorts in Avon Park, Sebring, and Lake Placid, rigs sit on their sites through the summer their owners spend in Michigan. In the storage lots, uncovered rigs take the same rain with nobody checking on them at all. Covered storage helps genuinely; it does not make roofs immortal.

The pattern we see every November: an owner returns after six months away, and the first June downpour already found the seam that lifted in April. If your rig summers in Highlands County without you, a spring inspection and reseal before you leave is the cheapest insurance available. We do these calls all April and May, and it is the least crowded time on our schedule.

What it costs and how to book

Trip fee $75 to $150 in the local area; labor $125 to $190/hr within those job ranges. Full details on the pricing page, and the roof cost calculator prices it by rig length. Every number gets your approval before work starts.

Send us the year, make, and model, where the rig is parked, and when it was last resealed, if you know. If the answer is “no idea,” that is itself the answer: it is time to get eyes and a camera up there. If it is currently leaking, say so, active water intrusion jumps the queue. More questions?
