# Full Roof Replacement: Cost, Hours and Process in Hacienda Heights Full roof replacement strips the membrane and every rooftop component, replaces compromised decking and framing, and installs a new membrane with all penetrations rebuilt. It is the correct answer when moisture has reached the substrate across more than roughly a third of the deck, or when the membrane itself has failed in the field rather than at a joint. ## Specifications - Price band: $3,500 to $18,000 plus - Shop hours: 20 to 80 plus hours - Turnaround tier: Structural - Insurance billable: yes - Parts lead time: 10 to 20 business days for full width membrane and decking - OEM brands: Alpha Systems, Dicor, Carlisle SynTec, Lippert, Dometic, Fan-Tastic Vent ## When replacement is the honest recommendation We would rather repair a roof than replace one, because a repair is faster and cheaper and keeps a customer. But there is a point past which a repair is just a deferral you pay for twice, and the moisture map tells us where that point is. The practical threshold is roughly a third of the deck reading wet, or any wet reading in the framing rather than only in the decking. Once the rafters are involved, sectional work means opening the membrane in several places anyway, and the labor to do that repeatedly exceeds the labor to do it once correctly. The other trigger is field failure. A membrane that has gone brittle across the entire surface will open somewhere new every season regardless of how well the joints are done. At that point the membrane has reached end of service and no amount of sealant addresses it. ## What the job actually involves Everything on the roof comes off: air conditioners, vents, fans, skylights, antennas, solar, racks, ladder brackets and the front and rear cap transitions. The membrane is stripped to the deck. Every fastener is removed. Decking is then evaluated panel by panel. Wet material is cut out and new decking scarfed in flush to the existing plane, which matters because a step in the deck telegraphs through a new membrane and becomes a wear point. Where a rafter is compromised, it is sistered or replaced. The new membrane goes down in a single piece across the width wherever the coach allows it, bonded with the adhesive system the membrane manufacturer specifies. Then every component is reinstalled on fresh butyl with new fasteners and finished with the correct sealant for that surface. The last step is a water test, not a visual check. The coach gets wetted down under pressure at every transition and read for intrusion before it is called finished. - Full component removal and cataloguing - Membrane strip to bare deck - Panel by panel moisture evaluation and decking replacement - Rafter sistering or replacement where indicated - New membrane with manufacturer specified adhesive - Component reinstallation on fresh butyl with new fasteners - Pressure water test at every transition before release ## Cost, hours and the insurance question The band on this page is wide because coach length and decking condition drive it more than anything else. A 24 foot towable with sound decking is near the bottom. A 40 foot diesel pusher with two thirds of the deck wet and three rafters involved is at the top and can exceed it. Labor runs at the posted body and paint rate of $210 per hour across 20 to 80 plus hours. Because this is a teardown scoped job, the estimate tier is the collision teardown at one hour of body rate, credited against the authorized repair, rather than the systems estimate. On the carrier side, a full replacement is frequently a supplement conversation rather than a first pass approval, because the initial estimate is usually written off visible damage and the decking is not visible. We photograph the moisture map and the stripped deck specifically so that supplement is documented rather than argued. ## Whether an older coach is worth it This is the question owners actually want answered, and the answer is arithmetic rather than sentiment. A roof replacement on a coach with a sound drivetrain, a good interior and no delamination is usually worth it, because the roof is what threatens everything else and nothing else on the coach is failing. A roof replacement on a coach that already has sidewall delamination, a soft floor and a failing slide is a different calculation, and we will say so. In that case the roof is a symptom of long term storage exposure and the total of what needs doing may exceed what the coach is worth. We give you the moisture map and the scope in writing so that decision is yours to make on real numbers. What we will not do is quote a roof on a coach where we can see the rest of the envelope is going, without telling you what we saw. ## Not included - We do not install a new membrane over decking that still reads wet. - Interior ceiling and cabinet reconstruction is quoted as interior work, not roof work. ## Questions **How much does a full RV roof replacement cost?** The band on this page covers it, and coach length plus decking condition drive where you land inside it. A short towable with sound decking is near the bottom. A long diesel pusher with widespread wet decking and rafter involvement is at the top or beyond it. The teardown estimate produces the actual number. **How long will my coach be out of service?** Three to eight weeks in most cases. The labor is 20 to 80 plus hours but the calendar is longer than the labor because membrane lead time runs 10 to 20 business days and adhesive cure windows cannot be compressed. **Will insurance pay for a full roof replacement?** Where a covered event caused it, frequently yes, though usually as a supplement rather than on the first estimate, because decking condition is not visible when the adjuster writes it. Where the cause is long term seal failure, carriers generally treat it as maintenance. We document the distinction with a moisture map and stripped deck photographs. **Can I change roof material during a replacement?** Often yes, and it is worth discussing. Moving from an aging EPDM to a TPO membrane is a common upgrade because TPO handles UV better, which matters in this region. The constraint is the roof profile and the cap transitions, and we confirm compatibility before committing to a material. **Do you replace the interior ceiling as part of the roof job?** Not as part of the roof line item. Where water reached the ceiling panels they usually need attention, and we quote that as interior work so you can see the two scopes separately and decide on each. Keeping them separate also matters on a claim, because they can be adjusted differently. --- Source: https://ocrv.club/rv-roof-repair/full-roof-replacement OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887 Phone (949) 799-3387.
