Once fractures pass roughly ten per section, **replacement beats patching**. Range $1,500 to $18,000+. ## How is hail damage on an RV roof repaired and scoped? Hail damage roof repair on an RV starts with chalked test squares, a dimple count per square and a fracture map, then either patching or full membrane replacement. Rancho Santa Margarita owners bring hail claims to our Yorba Linda shop, where the scope is written to match how carriers actually measure hail. - An RV roof has no panel matrix, so hail is counted per test square - Vent lids, skylight domes and air conditioner shrouds fail first - A fresh patch on an oxidised roof never matches and never will - Many policies carry a separate percentage wind and hail deductible ### Key facts | Item | Value | | --- | --- | | Price range | $1,500 to $18,000+ (10 to 80 labor hours at $210 per hour) | | Labor rate | $210 per hour (Body and paint department, plus supplies) | | Typical turnaround | 8 to 25 shop days (Supplement approval, not bench time, is the usual delay) | | Estimate | $150 written (The estimate fee is $150 and it is credited in full when the repair proceeds) | | Test square method | Four chalked squares per roof section (Ten inch squares, counted and photographed with a scale in frame) | | Replacement threshold | About 10 fractures per section (Beyond that, patching costs more than reskinning and holds worse) | Hail claims are the one roof job where the repair plan is written half by the shop and half by the carrier. The physical work is not exotic. What decides the outcome is whether the damage was measured in a way an adjuster recognises, before anybody touched it, and whether the estimate speaks the language a hail file is settled in. Almost none of the hail we see fell in Rancho Santa Margarita. Orange County gets hail once in a long while and it is rarely destructive. The units that arrive here were caught in an Arizona monsoon cell, a Texas spring storm on a snowbird run, or a Front Range hit while parked at a relative's house in Colorado. That geography matters, because it means the date of loss and the storm report are usually the first things we go looking for. ## How carriers scope hail on an RV roof compared with a car Automotive hail has a settled methodology. The vehicle is broken into panels, each panel gets a dent count and a size band, and a matrix converts that into paintless dent repair hours. Every adjuster in the country works from the same structure and the arguments are about numbers within a known framework. An RV roof breaks that framework completely. There are no panels. There is one continuous membrane or one bonded laminate, and none of it can be pushed back out from behind. The unit of measure has to become area rather than panel, and the damage that matters is not cosmetic denting but fracture and bruising in a waterproofing layer. So the scope has to be built differently. We divide the roof into sections, chalk ten inch test squares in each, count impacts inside them, and photograph every square with a ruler in frame. That gives an adjuster a countable, verifiable figure they can go check themselves. It is borrowed straight from residential roofing practice, and it works because it is the method their own training already recognises. ## Counting dimples, bruises and fractures, and why the three differ Not every mark is the same loss. A dimple is a depression with the sheet intact. A bruise is a dimple where the membrane has thinned and lost integrity without opening yet, and it reads noticeably softer under a thumb. A fracture is a dimple that has split, and it is leaking today whether or not anybody has seen water inside. Fractures are what drive the repair decision. They cluster between rafters, because a membrane over an unsupported bay has nothing behind it to spread the impact, while the same stone directly over a truss usually leaves only a mark. Backlighting from inside the coach with a ceiling panel dropped turns marginal fractures into obvious ones. Bruises are what drive the argument. They are real, they are documented in roofing literature, and they open within a season or two. Getting them counted in the original scope is much easier than reopening a closed file next spring to explain why a roof that was settled in March is leaking in October. - Dimple: depression only, sheet intact, count it and note it - Bruise: thinned membrane, reads soft, will open later - Fracture: split at the impact, leaking now, drives the repair decision - Fractures concentrate between rafters, not over them ## When a hail damaged roof gets replaced instead of patched There is a point where patching stops making sense and it is arithmetic rather than opinion. Each patch carries its own labor, its own materials and its own perimeter of sealed edge. Around ten discrete fractures in one roof section, the labor to cut, prime, bond and dress all of them approaches the labor to strip that section and lay a single new sheet, and the new sheet has one perimeter instead of ten. Two other findings force replacement regardless of count. Any decking that reads wet has to be opened, and once the membrane is off a large area you are already most of the way to a reskin. And an aged, oxidised membrane that fractured at small stone sizes has lost its elongation everywhere, not only where it was hit, so patching it is repairing the part that failed first rather than the part that is weak. We put both numbers on the estimate. Patch count priced out, section reskin priced out, side by side. That makes it a decision the owner and the carrier can both see, rather than a recommendation they have to take on faith. > **insurance:** Ask your carrier whether the policy carries a separate wind and hail deductible. Many do, often as a percentage of insured value rather than a flat figure, and it changes the owner's share substantially. ## Matching a repair to a roof that has been in the sun for nine years This is the conversation nobody enjoys. A new white patch on a nine year old EPDM roof is a bright rectangle in a field of grey, and it will stay visible for years because the surrounding sheet oxidised slowly and the patch has not started. On TPO the mismatch is less dramatic but still obvious at the seam. Cosmetic mismatch on a roof is not a coverage argument the way a mismatched fender is, since almost nobody sees it. Where it matters practically is that the visible boundary tells you exactly how much of the original roof is now a different age than the rest, and that is a maintenance map for the next owner. On a unit heading for sale, that visual is worth factoring into the repair against replace decision. ## What hail does below the roofline Hail rarely falls straight down. Wind drives it at an angle, and the storm facing sidewall takes real damage that a scope written from the roof will miss entirely. Aluminum siding dimples. Fiberglass front caps craze and star. Window frames and awning rails take hits that show as small dents until you read them under a raking light. Underneath the air conditioner shroud is the other commonly missed item. Split shrouds are obvious. Flattened condenser fins are not, and an air conditioner with restricted airflow runs hot for weeks and then fails in a way that is very difficult to attach to a storm three months earlier. We pull the shroud and photograph the condenser on every hail file for exactly that reason. ## Cost, deductibles and what the owner actually pays Hail work bills at the body and paint rate of $210 per hour, with supplies on top and parts at standard markup. Tax applies to parts and materials, not to labor. The estimate fee is $150 and it is credited in full when the repair proceeds. Deposits apply above $2,000 where the work is not being billed to a carrier. The number that surprises owners is not our number, it is the deductible. Plenty of RV policies carry a separate wind and hail deductible expressed as a percentage of insured value, which on a well insured fifth wheel can be several thousand dollars against a flat collision deductible of five hundred. Reading that clause before filing is worth doing, because on a smaller hail loss it occasionally changes whether filing makes sense at all. ## Documenting a hail loss so the file holds together Three things make a hail file settle cleanly. A date of loss that matches published storm data for the location. Photographs taken before anything was cleaned up, with a scale in frame. And a counted, chalked test square method an adjuster can verify by climbing up and repeating it. The most common way owners damage their own claim is tidying. Sweeping up broken lid fragments, washing the roof, or having somebody tape a fracture before the inspection all remove evidence that cannot be recreated. If the unit has to be made watertight before an adjuster can attend, photograph everything first and tell the carrier what was done and why. ## Cost $1,500 to $18,000+, based on 10 to 80 labor hours at $210 per hour. Written repair estimate is $150, credited in full against an authorized repair. All work is performed in shop. ## Questions and answers ### What is a test square and why does my hail estimate have four of them? It is a chalked ten inch square on the roof with every impact inside it counted and photographed against a ruler. Four per roof section gives a density figure an adjuster can verify by repeating it. RV roofs have no panel matrix like a car, so a countable density is the closest thing to a standard measure. ### The roof is dimpled but not leaking. Is that still damage? Yes, if the membrane is bruised. A bruise is a thinned impact site that reads softer than the sheet around it and has lost integrity without opening yet. Those open within a season or two. Counting them in the original scope avoids trying to reopen a settled claim after the roof starts leaking. ### At what point does hail damage mean a new roof rather than patches? Around ten discrete fractures in one roof section, the labor and materials to patch them all approach a section reskin, and the reskin gives one continuous sheet instead of ten patch perimeters. Wet decking or an aged membrane that fractured at small stone sizes both push toward replacement regardless of count. ### Why is my hail deductible higher than my collision deductible? Many RV policies carry a separate wind and hail deductible, often written as a percentage of insured value instead of a flat amount. On a well insured fifth wheel that can be several thousand dollars where the collision deductible is five hundred. It is worth reading that clause before deciding to file. ### The hail happened in another state months ago. Can I still claim? Often yes, but causation becomes the hard part. We match your reported date of loss against published storm data for that location and document the damage pattern, which is what connects an Arizona monsoon in July to a unit standing in Orange County in October. Report it as soon as you find it. ### Should I tidy the roof before the adjuster comes out? No. Broken lid fragments, impact marks and debris are the evidence the claim rests on and they cannot be recreated. If the unit has to be made watertight before an inspection can happen, photograph everything in place first, then tell the carrier what was done and why it was necessary. --- Source: [OCRV Center](https://ocrv.me/services/roof-repair-and-replacement/hail-damage-roof-repair/).
