Running an RV roof coating business: what to charge per job

What RV owners pay for a spray-on roof

Spray-on RV roofs are sold by the linear foot, and ThePricer's 2024 data puts the going rate at $130 to $200 a foot across four brands. FlexArmor sits at the top with a median of $185. Florida winter promotions have dipped to $130, and some West Coast jobs top $210.

Owner bills land inside those ranges. An RV owner on a Jayco forum reported paying RV Armor $5,250 for a 30-ft RV in October 2025, or $175 a foot. ThePricer also published three invoices.

Repairs and roof hardware are where a bill grows. The fifth wheel carried $900 of plywood and vent covers on top of the coating, and the coach needed new decking and six solar panels pulled. Price those as separate lines.

ArmorThane's RV roof page puts a 30-ft rig at $3,500 to $7,000, about $117 to $233 a foot, which is wider on both ends than any single brand range in ThePricer's data. This site is sponsored by ArmorThane USA of Springfield, Missouri, which sells applicator startup packages, so read its figures with that in mind.

You also compete with the roll-on can. The same Jayco post listed DIY roof products for a 30-ft RV at roughly $90 to $1,200. Your quote has to show what the owner gets for the difference: a stated film thickness, prep done right and a written warranty.

Revenue per job by RV length

Because the market prices by the foot, revenue per job is length times rate. The table runs four rates from the brand ranges above. These are not quotes. They show how far your rate moves each ticket.

On a 35-ft rig, the gap between $130 and $200 a foot is $2,450, and it repeats on every roof. A low rate can still pay if your costs are low. You only know once you run the material and labor math below.

Put your own rate, job count and equipment cost into the calculator to see how many roofs pay back the rig.

Material math, step by step

A 300 sq ft roof sprayed at 60 to 80 mils with a 100% solids product takes about 11 to 15 gallons before waste. Run this math on every quote.

1. 1

   Start with the gallon

   A gallon is 231 cubic inches. A square foot at 1 mil (0.001 inch) holds 0.144 cubic inches, so a gallon covers about 1,604 sq ft at 1 mil.

2. 2

   Divide by film build

   At 60 mils that is about 26.7 sq ft per gallon. At 80 mils, about 20.

3. 3

   Divide the roof by coverage

   300 sq ft needs about 11.2 gallons at 60 mils and about 15 at 80.

4. 4

   Add waste

   Overspray, purges, test patterns and wrapped edges all use material. Track your real waste on early jobs.

5. 5

   Price the whole system

   Multiply by your supplier's current price per gallon, then add primer, topcoat and sealant.

This matters for pricing. Going from 60 to 80 mils is a third more material on the same roof. And a per-foot price hides square footage, since two 35-ft rigs can differ in width and caps. Measure before you set a rate.

Thickness explains part of the gap between brands. ThePricer lists Rhino at 100 mils, Spray-Lining at 80, RV Armor at 70 and FlexArmor at 187 (the same page also calls FlexArmor a quarter inch, so check with the brand). At 187 mils, a 300 sq ft roof takes about 35 gallons.

A product with solvent in it covers less than a 100% solids product at the same dry thickness. Public per-gallon dealer pricing is scarce and dated, so get current prices from your supplier. On bedliners, ArmorThane's cost guide says aliphatic (UV-stable) material adds 30-45% to material cost, so ask whether your roof system uses one.

How long a job takes

ArmorThane puts an RV roof at 1 to 2 days of work. ThePricer says FlexArmor installs take 2 to 3 days at a certified facility. Either way, a roof ties up a bay and a crew for days, not hours.

CostInsightHub puts a bedliner install at 2 to 5 hours, and ArmorThane's cost guide puts most beds at $525 to $700. One roof can hold the bay as long as several beds, so judge the work by revenue per bay-day.

As arithmetic, the $5,250 RV Armor job spread over two days is $2,625 of gross revenue a day, before material, labor and overhead. Run it with your rate and the days your crew actually takes.

Build weather into the schedule, since data sheets set temperature and humidity limits and outdoor jobs lose days to rain and wind. ThePricer reports waits of about two weeks in Florida and six to eight weeks in low-density regions, a hint that some areas have few installers. Check your own area first.

Who buys, and where to find them

The buyer is the RV owner, often one with a leak, a worn membrane or a roof they are tired of resealing. These owners research before they spend thousands, and forum threads comparing brands and prices are easy to find.

Insurance can be part of the sale. One invoice ThePricer cites, a 34-ft Tiffin Allegro Red in 2024, came to $6,732, and insurance paid $4,950. Learn what adjusters in your area ask for.

• RV dealers. Service departments that do not spray roofs may refer work or send used units before resale.
• Storage lots. Rigs sit there for months, and a lot owner may let you post offers or work on site.
• Campgrounds and RV parks, especially long-stay and seasonal sites.
• Mobile RV techs and repair shops that find roof damage but do not coat.
• Owner forums and clubs, where people compare brands and post what they paid.

There is no good public data on which channel produces the most jobs. Track the source of every lead from your first quote.

Mobile work vs. shop work

A mobile setup needs a generator and an enclosed trailer beyond the base spray system, according to ArmorThane's applicator page. A shop needs a bay big enough for the rig.

Some shops do both: roofs in the bay when the rig fits, mobile jobs when it does not. The equipment cost guide covers what a mobile rig adds.

Prep and quality problems behind warranty claims

In coatings work, adhesion problems are usually prep problems, and prep is where a new installer is most tempted to save time. Common causes of callbacks:

• Silicone and old sealant left on the roof. Coatings tend not to bond to silicone residue.
• Wet or rotten decking. Coating over soft wood seals the problem in. Two of the invoices above included decking or plywood.
• Wrong primer. EPDM, TPO, fiberglass and aluminum each need the prep your supplier specifies.
• Thin spots at edges, seams and vents. Check film build with a wet film gauge as you go.
• Bad weather windows. Follow the data sheet limits on temperature, humidity and dew point.
• Penetrations. Leaks at vents, AC units, skylights and solar mounts get blamed on the coating.
• Overspray on paint, windows or awnings, a claim that has nothing to do with the roof.

Customers will compare your warranty with the big names. ThePricer lists lifetime warranties from FlexArmor (transferable) and RV Armor (non-transferable), and 10-year terms from Rhino and Spray-Lining. Confirm current terms with each brand, and ask your supplier what material warranty backs yours.

Adding RV roofs to a bedliner shop

A bedliner shop already owns plural-component spray equipment, so RV roofs are a logical add-on. Do not assume your rig can spray the roof product, though. Ask your supplier, in writing, which of its roof products your proportioner, hose and gun can run at the film build you plan to sell.

Equipment class is part of that. ArmorThane prices a low-pressure setup at about $25,000 and a high-pressure one closer to $50,000, and some products are made for one class. New equipment belongs in your payback math.

• Bay size. A bay built for pickups may be too short or too low for a motorhome.
• Fall protection. Plan ladders, scaffolding or lifts and the safety gear to match.
• Insurance. Confirm your policy covers RV work and, if you go mobile, customer sites.
• Training. Get product-specific training before your first paid roof.

RV roof pricing checklist

Build each quote from your costs up, then check it against the market.

• Measure length and actual sprayable square footage.
• Confirm the system and film build: primer, base coat, topcoat.
• Gallons: square feet times mils, divided by 1,604, plus waste.
• Material at your supplier's current per-gallon prices.
• Labor for washing, prep, masking, spraying and cleanup over 1-2 days.
• Separate lines for decking, sealant removal, vent covers and solar panels.
• Travel and generator fuel on mobile jobs.
• Money set aside for warranty callbacks.
• A check against the market: $130 to $200 a foot in ThePricer's data.
• Scope, mils, warranty and exclusions in writing.
