RV Roof Coating vs TPO Replacement — How We Decide
Recoat when the membrane is aging but the deck is mostly sound. Replace with 60 mil TPO when there are widespread leaks, failed coating, or several soft areas. RV Roof 911 decides after photos or an on-site inspection — we do not upsell replacement on a roof that will take coating.
One travel trailer, one job: tear-off, rolling new TPO with adhesive, finished roof with the AC and vents back on.
Recoating
Roof membrane is aging but structurally sound — chalking, fading, or minor cracks without widespread soft decking.
Starting recoating prices by length: $2,400–$3,700. Warranty (when the deck is solid): 8–10 year transferable warranty (standard).
A properly applied two-layer coating system reflects heat, seals micro-cracks, and adds years of life without full tear-off.
60 mil TPO replacement
Multiple leaks, widespread delamination, failed coating, or soft decking in several areas.
Starting replacement prices by length: $3,800–$6,200. Warranty: 10–12 year standard warranty on materials & workmanship.
When the existing membrane is beyond restoration, a new TPO system is the most reliable long-term waterproofing solution.

On-site inspection is $85. A photo estimate is free.
We work on TPO / membrane roofs for Class A, Class C, fifth wheels, travel trailers, and similar coaches. Mobile service within about 70–80 miles of Rancho Santa Margarita, California.
What we do
- Review photos or walk the roof in person.
- Check membrane condition: chalking, cracks, failed coating, open laps.
- Probe the deck for soft spots.
- Recommend recoating if the sheet and deck will hold it.
- Recommend 60 mil replacement if leaks are widespread, coating has failed, or several areas are soft.
- Write the quote from the live catalog, then you decide.
Questions
Should I recoat my RV roof or replace it with 60 mil TPO?
Recoat when the membrane is aging but the deck is mostly sound. Replace with 60 mil TPO when there are widespread leaks, failed coating, or several soft spots. We decide after photos or an on-site inspection — not a nationwide shop, and not a house-roofing company.
Is silicone coating cheaper than a new TPO roof?
Yes at the starting-price level: recoating $2,400–$3,700 vs replacement $3,800–$6,200 by RV length. If the deck is rotten in several places, replacement is the honest job.
Will you coat over a leaking, rotten deck?
No. Soft plywood has to come out. Coating over rot fails.
