Hail Damage RV Roof Repair, Scoped the Way Carriers Scope It
Written by Claims Coordinator, Insurance Claims Coordinator, OCRV Center. Reviewed by Structural Repair Lead
In shortHail on an RV is scoped by test square and square footage, not by panel like a car. 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
- Price range
- $1,500 to $18,000+10 to 80 labor hours at $210 per hour
- Labor rate
- $210 per hourBody and paint department, plus supplies
- Typical turnaround
- 8 to 25 shop daysSupplement approval, not bench time, is the usual delay
- Estimate
- $150 writtenThe estimate fee is $150 and it is credited in full when the repair proceeds
- Test square method
- Four chalked squares per roof sectionTen inch squares, counted and photographed with a scale in frame
- Replacement threshold
- About 10 fractures per sectionBeyond 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.
On the claim
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.
What is included
- Chalked test squares with a dimple count
- Four ten inch squares per roof section, counted, chalked and photographed with a ruler in frame so the count is verifiable later.
- Fracture map of the whole roof
- Every penetrating fracture is marked and numbered on a roof diagram that goes into the estimate as an exhibit.
- Date of loss and storm data pull
- We match the reported loss date against published storm reports for the location, which is what supports causation on an out of state event.
- Full plastics inventory
- Vent lids, skylight domes, shrouds, antenna housings and solar frames are listed individually with model numbers rather than as a lump.
- Repair against replace calculation
- The patch count is priced against a section reskin so the decision is made on numbers instead of on preference.
- Sidewall and cap inspection under raking lightwhere applicable
- Wind driven hail damage on vertical panels is scoped separately and added to the same claim.
- Supplement package if the first scope falls shortwhere applicable
- Photographs, counts and the fracture map are submitted as one document rather than as a phone call.
How the work runs
Establish the loss before touching the roof
1 hour
Date, location and storm data come first. On a unit that took hail in another state months earlier, causation is the hardest part of the file, and it is far easier to build before a repair order exists than after.
Chalk, square and count
2 to 4 hours
The roof is divided into sections and four ten inch test squares are chalked in each. Impacts inside each square are counted and photographed with a scale. This is the number an adjuster can check, which is exactly why we produce it.
Map the fractures and inventory the plastics
2 to 5 hours
Every penetrating fracture is numbered on a roof diagram. Lids, domes, shrouds and antenna housings are listed with part numbers. Backlighting from inside catches the fractures that are invisible from above.
Run the repair against replace numbers
1 to 2 hours
Patch labor and materials for the counted fractures are priced next to a section reskin. Where the two are close, we recommend the reskin, because a patched roof has enormous edge length and every edge is a future maintenance point.
Execute and flood test
6 to 60 hours
Whichever route is authorized, all disturbed flanges are rebedded on fresh butyl and topped with self leveling sealant, then the roof is flooded and held while a technician watches the interior ceiling for the full test period.
What this costs
$1,500 to $18,000+
10 to 80 labor hours at $210 per hour, body and paint.
- Paint supplies at $55 per paint hour.
- Body supplies at $5 per body hour.
- Parts at $100 or less carry 100 percent markup. Parts over $100 carry 35 percent. Special order parts require a full non refundable deposit at order.
- Sales tax of 7.75 percent applies to parts and materials. Labor is not taxed.
- A 50 percent deposit is taken at authorization on any job over $2,000, with an additional 25 percent when parts arrive on any job over $10,000. Final balance is due at pickup.
- Plastics only, meaning lids, a dome and a shroud with a low fracture count, sits at the bottom.
- Full membrane replacement plus sidewall refinish on a forty foot fifth wheel sits at the top.
- Percentage based wind and hail deductibles change the owner's share substantially and should be read before the claim is filed.
How estimating is billed
- Written repair estimate: $150, credited in full against an authorized repair.
- In depth diagnostic, scan and programming: $285 per hour, one hour minimum, credited in full against an authorized repair.
- In shop pre purchase inspection: $400 to $1,200 depending on unit size and systems count.
- Insurance walk ins are accepted during posted hours. All inspection and estimating work is performed in shop at the Yorba Linda facility.
What you will notice first
- Round dimples in the membrane spaced roughly evenly across open areas
- A cracked or shattered vent lid with the fan still working underneath
- Star fractures in the skylight dome over the shower
- The air conditioner shroud split along a moulding line
- Bruised looking circles on the membrane that read soft when pressed
- Dents in the aluminum siding on the storm facing side of the unit
- Bent condenser fins visible through the air conditioner shroud opening
- Water appearing days after the storm rather than during it
How this fails, and what we do about it
| Failure mode | How we diagnose it | The fix |
|---|---|---|
| Membrane fracture over an unsupported bay | A dimple with a visible split at its centre, always found between rafters rather than over one. Backlighting from inside the coach with the ceiling panel removed makes marginal ones obvious. | Patch where the count is low. Once a roof section carries roughly ten or more of these, reskin that section, because a quilt of patches has more linear feet of edge than a new sheet has area. |
| Membrane bruising without penetration | A circle that reads softer than the sheet around it and shows a faint colour change. It does not leak today. Probing the underside through an opened section shows the sheet has thinned. | Document it, count it, and include it in the scope. Bruised membrane opens within a season or two, and getting it into the original estimate is far easier than supplementing for it later. |
| Cracked vent lid or skylight dome | Obvious on inspection, and it is the damage owners notice first. Check hinge pins and the garnish ring at the same time, since impact often distorts the frame rather than only the plastic. | Replace the lid or dome as a unit. Where the flange itself is deformed, the whole vent comes out and gets rebedded on fresh butyl rather than being sealed over. |
| Air conditioner shroud and condenser damage | The shroud splits along its thin moulded sections. Pull it and inspect the condenser: flattened fins reduce airflow and the unit will run hot afterward even though it looks undamaged. | New shroud, comb the fins where they are recoverable, and record the model and serial. Shroud availability by model year is a common cause of delay on hail files. |
| Sidewall and front cap dimpling | Wind driven hail loads the vertical surfaces. Read the sidewall with a light held at a low angle so the dimples throw shadows, then chalk them the same way you chalk the roof. | This becomes body and paint scope in its own right. It belongs on the same claim, and it is the item most often left off an initial adjuster scope written from the ground. |
Why it happened
- Direct impact fracturing a membrane over an unsupported bay between rafters, where the sheet has nothing behind it to spread the load
- Brittle plastic components reaching their impact limit first, which is why lids and domes are the visible damage on almost every hail file
- Sustained hail of smaller stone size producing bruising rather than penetration, which does not leak on day one and does within a year
- Impact on aged and oxidised membrane, which has lost elongation and fractures at stone sizes a newer sheet would have shrugged off
- Wind driven hail arriving at an angle, which loads the sidewall and the upper front cap rather than only the horizontal roof
- Secondary damage from foot traffic during a post storm inspection on a roof already compromised by impact
Parts and brands we work with
- Replacement EPDM and TPO sheet stock for full section reskins
- Fan-Tastic Vent and MaxxAir lids, domes and complete vent assemblies
- Specialty Recreation and ICON skylight domes in common 16 by 24 and 22 by 22 sizes
- Dometic and Coleman air conditioner shrouds and condenser fin combs
- Dicor self leveling lap sealant and butyl tape for every flange disturbed
- Lauan and OSB decking where impact drove through to the substrate
What not to try yourself
- Cleaning up the roof before the adjuster sees it. Removing broken lid fragments and washing away impact marks destroys the evidence the claim rests on, and there is no way to recreate it afterward.
- Accepting a scope written from the ground. Hail on an RV roof cannot be assessed from a ladder at the rear, and initial scopes written that way routinely miss the fractures between rafters entirely.
- Patching bruised membrane and calling it complete. Bruises open later, usually after the claim has closed, and reopening a settled hail file is far harder than including the count at the start.
- Running the air conditioner with flattened condenser fins after a hail event. The unit will overheat, and a compressor failure three weeks later is a much harder item to attach to the storm.

There is a matrix, there is paintless dent repair, and everybody knows the game. An RV roof has none of that, and I have watched adjusters who scope hail every day of the week stand on one and not know what they are supposed to count. So we hand them something countable. Four chalked squares per section, a number in each one, a ruler in every photo. I have never had a carrier argue with a number they could go up and verify themselves. The files that stall are always the ones with no method behind them.
Appendix: 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.
