# Roof Recoat and Reseal: Cost, Hours and Process in Hacienda Heights Roof recoat and reseal is maintenance rather than repair. Every sealant joint on the roof is cut out, cleaned back and rebuilt, and the membrane field receives a fresh elastomeric coating. It is the cheapest line on the roof rate card and it is the work that prevents the most expensive line on it. ## Specifications - Price band: $750 to $4,500 plus - Shop hours: 4 to 20 plus hours - Turnaround tier: Light cosmetic - Insurance billable: no - Parts lead time: In stock. Coating and sealant are shelf stock in every roof chemistry we work with - OEM brands: Dicor, Alpha Systems, Eternabond, Lippert, Carlisle SynTec ## The arithmetic that makes this the best value on the roof Put the two numbers side by side. A full reseal with a field coating sits in the band on this page, $750 to $4,500 depending on coach length and how many penetrations are in scope. Full roof replacement starts at $3,500 and runs to $18,000 and beyond once decking and framing come into it. Run on a three to four year cycle, a reseal costs less across a decade than a single decking repair. Skipped entirely, the sealant opens, the deck takes water quietly for two years, and the same coach needs a job costing several times more with a three to eight week calendar attached to it. That comparison is the entire argument for this page. It is not an upsell. It is the cheapest thing we do to a roof and it is the only thing that reliably prevents the most expensive thing we do to a roof. ## Reseal and recoat are two operations, not one Reseal is joint work. Every penetration on the roof, and there are usually between fourteen and thirty of them, has its old sealant cut out to clean substrate, its fasteners checked and reset, and a new bead installed in the chemistry correct for that surface. This is where the hours go and it is what actually stops leaks. Recoat is field work. Once the joints are sound, an elastomeric coating goes over the membrane to restore the UV barrier the original surface has lost. It does not stop an active leak and it should never be sold as though it does. A shop that rolls coating over crazed sealant has sold you a color change. The coating bridges the cracks for a season, the joint underneath keeps moving, and the failure resumes exactly where it was with a layer of white acrylic hiding it from view. ## Choosing a coating that matches your membrane Roof chemistry is not interchangeable. A coating formulated for EPDM will not bond durably to TPO, a sealant meant for a rubber roof behaves differently on fiberglass, and nothing at all bonds to cured silicone, which is why silicone has to be mechanically removed before any of this starts. We confirm the membrane at intake, then select a primer and coating system rated for it. On EPDM that usually means an acrylic or urethane system over a bonding primer. On TPO it means a product specifically listed for thermoplastic. On fiberglass it looks much closer to a refinish than to a membrane coating. This is the single most common thing done wrong at a general shop, because a general shop stocks one product and uses it on everything. The result looks perfect at pickup and sheds coating in sheets eighteen months later, usually starting at the edges where it matters most. ## The interval that actually applies in this climate Manufacturers publish intervals written for a national average. Southern California is not the average. The UV dose on a coach stored uncovered here is high enough that sealant chalks and loses elasticity on a noticeably shorter clock than the printed figure assumes. In practice we tell owners storing outdoors in this part of Los Angeles County to inspect twice a year and expect a full reseal every three to four years. A coach kept under cover can go roughly twice as long. A coach that lives on the road splits the difference and takes more mechanical stress at the joints from flex. Inspection is not the same purchase as a reseal and it costs far less. A roof and seal inspection reads every joint and tells you which ones are actually due, which lets you spend on the joints that need it rather than resealing an entire roof because one bead looked bad. ## When we will decline to coat a roof There are three cases where coating is the wrong purchase and we will say so before you authorize it. The first is wet decking. A coating is a vapor barrier, and applying one over a wet deck traps the moisture inside the wood where it has no path out. The second is a membrane at end of service. A sheet that has gone brittle across the whole field keeps opening in new places under a coating, and you will have paid for a surface treatment on a roof that needed replacing. That money is better applied to the replacement. The third is a roof carrying old silicone or roofing tar from a previous repair. That material has to come off mechanically first, and on a badly treated roof the removal costs more than the reseal itself. We would rather you hear that number before the work starts than find it on an invoice. - Wet decking, coating traps the moisture in the wood - Brittle membrane at end of service, replacement is the better spend - Old silicone or roofing tar, mechanical removal comes first - Active leak at a flange, repair the joint before coating the field - Unknown roof material, chemistry gets confirmed before anything is ordered ## Not included - We do not coat a roof that reads wet at the decking. A coating is a vapor barrier and it seals the water into the wood where it cannot dry. - Recoating is not a repair. A torn membrane, an open seam or a failed flange is repaired first and coated afterward. - We do not perform reseal work at a customer location. Coating cure needs a covered bay and a controlled temperature window. ## Questions **What is the real reseal interval for a coach stored outdoors here?** Every three to four years, with a visual check twice a year in between. That is shorter than the printed interval because the UV load in this part of Los Angeles County is higher than the national average the manufacturer wrote for. Covered storage roughly doubles the interval. **Will a roof coating stop a leak I already have?** No, and anyone who tells you otherwise is selling paint. A coating restores the UV barrier across the membrane field. An active leak is a joint that has opened, and the joint has to be cut out and rebuilt first. Coating over it hides the failure for a season and then it returns. **Is roof recoating covered by insurance?** No. Recoating is scheduled maintenance and carriers do not pay for maintenance on any vehicle. Where a covered event damaged the roof, the repair to that damage is claimable and the reseal work around it is generally not. We keep the two scopes on separate lines so the file stays clean. **Can you coat a TPO roof with the same product used on rubber?** No. TPO is a thermoplastic and EPDM is a cured rubber, and a coating system rated for one does not bond durably to the other. We confirm the membrane before selecting a primer and coating, which is why the roof material is one of the first questions asked at intake. **How much does a full RV roof reseal cost?** The band on this page covers it. Coach length and penetration count are what move you inside it, along with how much unsuitable sealant from previous work has to be removed. Labor is at the posted body and paint rate of $210 per hour across roughly 4 to 20 hours, and the systems estimate at $150 produces the real number. --- Source: https://ocrv.club/rv-roof-repair/roof-recoat-and-reseal OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887 Phone (949) 799-3387.
