A month before this, we spent four days replacing a roof. This is the job that one wasn’t. Same complaint, same starting point from the ground — and the deck underneath was still sound, so it took an afternoon.
What a reseal actually is
It is not running a fresh bead over the old one. That is the version that gets sold cheaply and fails quietly, because new sealant bonded to old, chalked, oxidized sealant is bonded to nothing — it is a skin over a joint that is already open underneath.
A reseal means the old material comes off. Every roof penetration gets scraped and cleaned back to the flange and the membrane, the substrate gets inspected while it is exposed, and fresh self-leveling sealant goes on to clean material. The cleaning is most of the labor. The sealing is the quick part.
Where RV roofs actually leak
Almost never in the middle. The open field of a membrane is the part with nothing going through it, and it is the part everyone looks at. Water gets in where something interrupts the roof:
- The front and rear cap seams. The highest-stress joints on the coach. They flex every mile you drive and they are where we found the most work on this one.
- The A/C gasket. Compresses over time and after the unit has been off and back on.
- Vent and fan flanges — bathroom vents, range hood, the powered fan.
- Plumbing vent pipes. Small, easy to miss, directly above a wall cavity.
- Antenna and satellite bases, marker lights, ladder brackets, solar mounts — anything screwed through.
- The termination bar where the membrane meets the sidewall.
That is the whole list, and it is why a reseal is a methodical job rather than a quick one. There is no point doing four of those and not the fifth.
The afternoon, in order
How the deck decided the price
Nothing about the first ten minutes of this job looked different from the first ten minutes of the four-day replacement. Hard, cracked, shrunken sealant at the penetrations; a roof that looked tired from the ground.
The difference was underfoot. This deck was firm everywhere — no give, no sponginess, no soft spots around the fittings. That single check is what separates a two-hour job from a four-day one, and it costs nothing to make.
If you want to see what the other outcome looks like, the replacement is documented photograph by photograph, including the seven minutes between “the membrane has failed” and “the decking is coming out in handfuls.”
How often should this be done?
The honest answer is that a calendar is the wrong tool. Sealant fails on ultraviolet exposure and movement, and a coach that lives outside in Central Texas ages sealant considerably faster than one that lives under cover in a mild climate. Two rigs the same age can be years apart.
What we would actually suggest:
- Look at the roof twice a year — before the summer and after it. Ten minutes.
- Look after any hail. Hail damage is also very often an insurance claim rather than a repair bill, which is worth establishing before you pay for anything.
- Reseal when the sealant tells you, not on a schedule. Hard, cracked, shrunk back from the edge, or lifting at an edge you can get a fingernail under — those are the signals.
- Do the whole roof at once. The labor is in getting up there and cleaning; adding the last two fittings costs very little and is the difference between a repair and a gamble.
Done in the park, where it was parked
The coach never moved. That matters more for a reseal than people expect: fresh self-leveling sealant needs to sit and cure undisturbed, and a roof that has just been stripped back is an open roof until the new material is on and set.
Not sure which one your roof needs
A roof inspection gives you a written condition report and a straight answer — reseal or replace — before you commit to either.
We would rather tell you it is a reseal.
