ArmorThane 2026 estimate

An RV roof quote is one of the easiest bills in the RV world to misread. Two shops can look at the same 30-foot trailer and come back $10,000 apart, and both can be honest, because one is a dealer tearing off and putting back the same membrane and the other is an independent shop charging by the foot.

Quick answer

Replacing an RV roof costs about $4,250–$9,200 for a 25- to 40-foot box at an independent shop or with a sprayed polyurea roof, which works out to roughly $170–$230 per foot. Dealer service departments publish $7,000–$18,000. Rotted decking adds $1,500–$6,000. A DIY TPO kit runs $700–$900 in materials. And if the deck is solid, a reseal or recoat ($500–$3,000) may be all the roof needs. Price your RV or see if you need a new roof at all.

Most pages on this topic give you one owner's invoice, or a range so wide it's useless. So we did the tedious part. We lined up every published price we could find, from sprayed-roof networks, owner invoices, forum quotes, dealer ranges and our own applicators' pricing, dated each one and converted it to dollars per foot of box length. That's how the people who quote these roofs actually price them.

A word on who's talking. We manufacture the polyurea and topcoats that ArmorThane-certified applicators spray on RV roofs, in Springfield, Missouri, and we've been at it for more than 35 years. We don't install roofs ourselves. That makes us biased toward sprayed roofs, and we'll say so where it matters. It also means we know what the material costs, what a fair per-foot price looks like, and when an owner should keep their money and buy a few tubes of lap sealant instead.

How much does RV roof replacement cost in 2026?

For a typical 25- to 40-foot travel trailer, fifth wheel or motorhome, expect about $4,250–$9,200 at an independent RV shop or for a sprayed seamless roof, and $7,000–$18,000 at a dealer. The length of the box, the condition of the deck underneath and who does the work decide where you land.

Two things jump out. First, at an independent shop a new membrane and a sprayed seamless roof cost about the same per foot. Second, the dealer premium is real: the published dealer ranges start where the independent and sprayed prices end. A dealer tear-off also tends to put back the same kind of membrane that failed, and one owner was quoted three to four weeks in the shop.

RV roof replacement cost per foot

Shops quote RV roofs by the linear foot of the box, measured from the front cap to the rear cap. A travel trailer's brochure length includes the tongue, so quoting from it overstates the roof by several feet. Measure it yourself before you compare quotes. Width barely varies: federal rules cap vehicle width at 102 inches (23 CFR 658.15), so most bodies are 8 to 8½ feet wide.

Our math, before any deck repair. Independent: $175–$230 per foot, the span of the two U.S. owner invoices above, with a $4,000 floor; that's thin data, so treat it as a sanity band. Sprayed: $170–$210 per foot. *One sprayed-roof network publishes a $4,560 minimum. Kits: Heng's TPO kits (membrane, adhesive, lap sealant, butyl tape) at United RV Parts, week of Sept. 26, 2026, sized at box length plus 2 ft; the 38-ft kit was listed for less than the 33-ft kit.

Camper roof replacement: trailers, fifth wheels, pop-ups and truck campers

"Camper" covers everything from a pop-up to a 40-foot fifth wheel, and the per-foot logic holds across all of them. Short rigs are the exception. Below about 24 feet, a shop's setup and minimum charges start to dominate, so a 17-foot trailer won't cost half of what a 34-footer does. Truck campers and pop-ups often have small, oddly shaped roofs where a patch, a reseal or a coating is the sensible repair. Get the deck checked before anyone quotes a full roof.

RV roof repair cost vs. replacement

Most roofs don't need replacing. They need their seams resealed. Our 2026 estimates from the RV roof repair guide put a DIY sealant refresh at $75–$200 in materials, a professional spot reseal at $300–$800, a full professional reseal at $1,000–$2,500 and a patch or section repair at $300–$900. Decking and rot repair runs $1,500–$6,000. If your roof has a sound deck and leaks at a vent or a cap seam, that's a repair, not a replacement. Our RV roof sealant guide picks the right product for each joint.

RV roof coating cost

A roll-on coating is the cheap middle path for a membrane that's tired but still intact. On a 30 x 8½-foot roof (255 sq ft), a thin acrylic spread at about 125 sq ft per gallon per coat (Camping World's figure for Dicor's rubber roof coating) takes a bit over 4 gallons for two coats, so buy 5. Thicker "liquid rubber" coatings published at about 50 sq ft per gallon take 5 to 6. Liquid Rubber itself calls for 5 gallons on a 30-foot RV and sells a 30-foot kit for $569.75. At $54.95–$79.95 a gallon, that's roughly $275–$570 in materials. A professional recoat runs $500–$3,000, and either one gets redone every three to five years. A sprayed polyurea roof is the other end of the "coating" scale: $170–$210 a foot, applied at 120 mils where parts-counter coatings go on at 30 to 40.

Ask before you sign
  • Tear-off or overlay? What happens to the old membrane?
  • How is deck repair priced: per sheet, per hour or a fixed allowance?
  • Are vents, fans, the A/C and antenna pulled and reset? Any new ones included?
  • New edge trim, termination bars and screws?
  • Which membrane brand and thickness, or for a sprayed roof, how many mils?
  • Whose warranty is it (installer, membrane maker, RV maker), what does it cover, and does it transfer?
  • How many days will the RV be in the shop?

How we calculated this: sprayed = box length x $170–$210; independent membrane = box length x $175–$230, at least $4,000; dealer = the published $7,000–$18,000 (fiberglass $11,500–$20,000+), not scaled by length because the sources don't give lengths. DIY coating gallons = area x 2 coats ÷ 125 sq ft/gal (thin acrylic) up to area ÷ 50 sq ft/gal (thick-film), priced at $54.95–$79.95 a gallon. Estimates only.

Replace, recoat or spray? RV roof options compared

There are really four ways to deal with a failing RV roof: reseal it, coat it, replace the membrane, or spray a seamless roof over it or over a new deck. The three replacement routes differ less in price than you'd expect, and more in how long they last and how much upkeep they need afterward.

Service lives are ArmorThane's figures from the RV roof repair guide; the sprayed-roof figure is our expected service life, not a warranty. Costs are the ranges above, before deck repair.

EPDM vs. TPO vs. PVC: which membrane to put back

EPDM rubber is the most common RV roof, especially on travel trailers and Class C motorhomes. It's a thermoset, so seams can't be heat-welded, and it chalks as UV breaks down the surface. TPO is a white, smoother thermoplastic that can be heat-welded in a shop. PVC is solvent-weldable and less common on North American RVs. Our repair guide puts service life at 12–20 years for EPDM with maintenance, 10–20 for TPO and 15–20 for PVC. The same water-based adhesive bonds all three (RecPro lists its 8010 for EPDM, TPO and PVC), so the install is similar. Pick the one your shop installs every week.

Read the membrane warranty closely. Dicor warrants its EPDM for 12 years against premature deterioration, but for the sheeting only: parts and labor for the first five years, prorated material only through year 12, and never the adhesive, lap sealant or installation. One PVC seller advertises a 15-year non-prorated warranty from its manufacturer. Neither covers the seams, and seams are where RV roofs leak.

Sprayed seamless roofs (polyurea)

A factory RV roof rarely fails in the middle. It fails at the front and rear cap seams, the termination bars and every penetration. A sprayed roof takes most of those joints away by putting one continuous membrane over the deck, the caps and the perimeter rail. Our applicators' spec is 120 mils, about three times the film of a roll-on RV coating. It's sprayed through heated plural-component equipment at roughly 2,000–3,000 psi with the material at 150–160°F, so it isn't a DIY product; there's no brush-on version of it.

Two honest caveats. Over EPDM it needs proper prep and a bonding primer, because rubber is hard to stick to; skip that and a coating can let go within a year. And vents, fans and the A/C get sealed into the same membrane, which makes them harder to pull for service later. Ask how your applicator handles removable penetrations before the gun comes out. Some applicators offer tiers, from spraying over a sound existing membrane to a full tear-off at 100 or 200 mils; our Phoenix applicator's page shows how that looks.

Roll-on coatings: acrylic, liquid rubber and silicone

Coatings buy back waterproofing on a membrane that's chalky or thin but still bonded and dry. They don't fix a soft deck, and they come back around every three to five years. Liquid Rubber backs a full-roof restoration with a 10-year product warranty, which replaces failed product if you used the required amount. Some shops sell multi-layer silicone systems. Know that once silicone is on a roof, almost nothing else will stick to it later, including lap sealant and tape; our silicone roof coating guide explains why.

Fiberglass and aluminum roofs

Fiberglass roofs last 20 years or more and usually fail at the gelcoat or around fasteners, so they're normally repaired or coated rather than replaced; the one published replacement range we found, $11,500–$20,000+, is a good reason to try that first. Aluminum roofs leak at seams and fasteners. Butyl tape, a metal seam sealer or a metal roof coating usually does it, much as it does on the metal roofs in our mobile home roof coating guide.

Why quotes differ

What drives RV roof replacement cost?

Length sets the baseline, and the deck sets the surprises. After that it's who does the work, how much is bolted to the roof, and what kind of rig it is. Here's what moves the number, roughly in order of how much.

Box length

Most shops price per foot, so every foot of box is roughly another $170–$230. Quote off the box, front cap to rear cap. Quoting off a trailer's brochure length, which includes the tongue, inflates the job.

The deck under the membrane

The biggest swing. Soft plywood or lauan has to come out before anything goes on, and our estimate for that work is $1,500–$6,000. Sprayed-roof networks price structural repairs separately, and so do most independent shops.

Who does the work

Dealer service departments publish $7,000–$18,000, with one owner quoted three to four weeks. Independent shops and sprayed-roof applicators land around $170–$230 a foot and often a few days. Mobile networks come to you.

Everything bolted to the roof

Each A/C unit, vent, fan, skylight, antenna, solar panel and ladder mount gets pulled, reset and resealed. The owner behind the $5,258 invoice lists these extras as a cost driver, and a rig with solar and two A/Cs takes longer than a bare roof.

Roof type and rig size

Fiberglass costs more to replace. So do big motorhomes: our repair guide notes a diesel pusher can land north of $12,000 once scaffolding and a week of shop time are in the bill.

Labor rate and location

Shop rates vary a lot by region. One Canadian worked example uses CA$95–$150 an hour. Ask any shop for its hourly rate and estimated hours next to the materials, so you can compare quotes line by line.

Sun matters too, just more slowly. The Department of Energy says conventional roofs can pass 150°F on a sunny summer afternoon, and heat and UV are what dry out lap sealant and chalk EPDM. Camping World says owners in hot, sunny climates reseal sooner, and our repair guide tells Arizona and west Texas owners to plan on the short end of a sealant bead's three-to-five-year life.

The swing cost

The hidden cost: rotted RV roof decking

A soft spot means water has been getting in for a long time, and no sealant, coating or new membrane fixes wet wood. The deck has to be cut out and replaced first, which is why two quotes for the same rig can differ by thousands. Budget $1,500–$6,000 if there's rot, and get it inspected before you compare prices.

How to check your deck in 20 minutes

  • On the roof: stay over the rafters and press as you go. A deck that flexes like wet cardboard is rotten.
  • Around the edges: front and rear caps, the side rails and every penetration, where most water gets in.
  • Inside: ceiling stains, a musty smell in a closed-up rig, soft cabinet tops along the outer wall.
  • In the walls: bubbles or waves in the sidewall mean water has already run down and separated the laminate. That's a structural repair.

Rot almost always runs farther than it looks. A shop can't price it exactly until the membrane is off, so ask how deck repair is billed: per sheet, per hour, or as a fixed allowance with a cap.

Technician on a work platform inspecting the roof edge and sidewall of an RV inside a shop
Most RV roof leaks start at the edges and penetrations, so that's where the inspection starts.

What deck repair involves

The honest version: pull the roof components, cut the membrane back to sound material, remove the wet decking, sister or replace it to the rafters, lay new decking, then glue down and seal a new membrane or spray the roof. Dicor's installation guide calls for at least ⅛-inch lauan under its TPO membrane, and ½-inch where the roof carries heavy loads, with the seams kept tight and anything wider than 1/16 inch taped.

Moisture matters for sprayed roofs as much as membranes. If a deck is still wet, or a roof is sprayed within 5°F of the dew point, moisture gets sealed in and the wood can keep rotting under a brand-new roof. Any reputable applicator inspects the deck first and tells you to fix rot before anything gets sprayed.

Should you repair, recoat or replace your RV roof?

Repair when the membrane is sound, the deck is solid and the damage is local. Recoat when the membrane is tired but intact with no soft spots. Replace when the deck is compromised, the membrane is torn across a large area, or the sidewalls are delaminating. The checker applies those rules to your roof and weighs the cost against what the RV is worth.

Cost vs RV value

A typical bill here (about $5,700) is 23% of the RV’s value. Easy to justify if the rest of the rig is sound.

Next step

What to do now

Clean and inspect first; a coating only works over a sound, dry roof. Keeping it five years or more? Price a sprayed seamless roof against three or four recoats.

Rules follow the repair, recoat or replace criteria in our RV roof repair guide. The 50% value test is our rule of thumb, not an industry standard.

Signs your RV roof needs replacing, not resealing

  • Soft spots in more than one place. The deck is compromised.
  • Leaks that keep turning up in new places. Usually the membrane itself is at the end of its life.
  • Bubbles in the membrane. The glue bond to the deck has let go, often from trapped moisture.
  • Tears across a large area, or a membrane worn thin enough to show the backing.
  • Sidewall delamination. The water has already gone down into the walls. That's a structural repair, and often where an older trailer stops being worth fixing.

A chalky, dull roof with cracked sealant and no soft spots isn't one of them. That's a clean-and-reseal or a recoat. Our repair guide walks through finding the actual leak, which is often several feet from the stain.

Can you replace an RV roof yourself? DIY cost and materials

Yes, if the deck is sound, you have a covered place to work and at least one helper. A TPO kit for a 30-foot box costs about $860, against $5,250–$6,900 at an independent shop. The catch is everything around the membrane: pulling the A/C and vents, fixing whatever rot you find, and gluing a 30-foot sheet down flat.

  1. Strip the roof

    Remove the A/C, vents, antenna, trim and moldings. Label screws and wiring as you go.

  2. Tear off, or overlay a new substrate

    Dicor's guide lets you "either remove the old roof or apply the new substrate over the old roof if removal will create structural damage." Either way, the new membrane goes on a clean, flat deck, not straight onto old rubber.

  3. Fix the deck

    Replace anything soft. Dicor calls for at least ⅛-inch lauan, ½-inch for heavy loads, fastened with tight seams; tape seams wider than 1/16 inch.

  4. Glue the membrane down

    Water-based adhesive covers about 160 sq ft per gallon. Don't stretch the membrane, and roll or broom it down for full contact.

  5. Cut in and bed the fixtures

    Route the openings, set vents and moldings on butyl tape, and reinstall everything.

  6. Seal

    Lap sealant in a ¼- to ⅜-inch bead over flanges, moldings and screw heads. No silicone, and no acetone or citrus cleaners on the membrane.

Shopping list
  • Heng’s TPO kit, 38 ft x 9 ft 6 in: $859.99. Includes membrane, bonding adhesive, lap sealant and butyl tape; the retailer page doesn’t list quantities, so check them against the counts below.

How we calculated this: membrane length = box + end-wrap allowance, matched to the cheapest kit or 9 ft 6 in roll at least that long. Adhesive = membrane area ÷ 160 sq ft/gal (Dicor), at $73.95 a gallon. Lap sealant and butyl = (2 x length + 2 x width + 6 ft per fixture) ÷ 30 ft per tube or roll, at $10.50 and $15.95. The 6 ft per fixture is our estimate.

Where DIY re-roofs go wrong

  • Rot found halfway through. Now the RV is open to the weather and the job has doubled.
  • Wrinkles and bubbles from a stretched membrane or adhesive that skinned over before the sheet went down.
  • Silicone or the wrong cleaner. Dicor's guide is blunt: silicone won't adhere to its TPO, and acetone and citrus cleaners are out.
  • Skipping the butyl under vents and moldings. Lap sealant on top isn't a substitute.

One thing you can't DIY at all is a sprayed polyurea roof; it needs a heated plural-component rig and training, and here's why the DIY versions disappoint.

Is a new RV roof worth it? The 10- to 20-year math

It depends almost entirely on how long you'll keep the RV. If your horizon includes the day the current membrane wears out, a new roof, sprayed or membrane, pays for itself against years of resealing followed by a replacement anyway. If you're selling in a few years, keep up the sealant and put the money elsewhere.

$5,700

Cheapest over 12 years: sprayed roof now at typical prices. Ranges (low to high prices and lifespans): maintain $225–$7,500, recoat $1,500–$9,900, new membrane now $5,500–$7,500, sprayed $5,100–$6,300. Your EPDM roof has about 8 years left at a typical 16-year life, so the maintain path includes one membrane replacement within your horizon. At typical prices the sprayed roof pulls ahead of maintaining if you keep the RV about 9 years or more. Assumptions: reseal every 3 years ($75–$200 DIY materials); recoats at $500–$1,000 don’t extend membrane life (tick the box if you think they will); no reseal cycle for the sprayed roof (ask your applicator). Today’s prices, no inflation.

How we calculated this: remaining life = typical life − roof age. Maintain = a reseal every 2–4 years plus an independent re-roof ($175–$230/ft) whenever the membrane wears out inside your horizon. Recoat = a $500–$1,000 recoat every 3–5 years instead of resealing. New membrane now = re-roof today plus resealing. Sprayed = $170–$210/ft today, with no reseal cycle assumed. The range uses low prices with long lives through high prices with short lives.

What the numbers say

Take a 30-foot EPDM roof that's 8 years old, resealed by the owner every three years. Kept 12 more years, the maintain path costs about $6,400, because the membrane wears out around year 8 and gets replaced at an independent shop. A sprayed roof today is about $5,700, and it pulls ahead once you keep the RV roughly 9 years. Now make the roof 3 years old and the horizon 8 years: maintaining costs about $300 in sealant, and spending $5,700 would be hard to defend. That matches what our repair guide says: a sprayed roof takes something like a decade to beat a disciplined reseal routine, so if you're selling in two years, don't do it.

Notice what the calculator can't count. A roof you don't climb onto four times a year is worth something to a lot of owners, and so is a transferable warranty when you sell. So is not having a leak run into the ceiling while the RV sits in storage. Those are real, but they're yours to weigh.

How to read an RV roof replacement quote and warranty

A good quote states the scope, not just a total: tear-off or overlay, how deck repair is priced, what happens to every fixture, the membrane brand and thickness (or, for a sprayed roof, the film thickness in mils), the time in the shop, and whose warranty you're getting. If two quotes don't list the same items, you can't compare them.

What a complete quote lists

  • Box length used, and the price per foot.
  • Tear-off or overlay, and disposal of the old membrane.
  • Deck repair terms: per sheet, per hour, or an allowance with a cap.
  • Fixtures: every A/C, vent, fan, skylight, antenna and solar mount pulled and reset, and any new parts.
  • Edge trim, termination bars and screws, new or reused.
  • Material: membrane brand and thickness, or product name and mils for a sprayed roof.
  • Days in the shop, and where the RV is stored while it's there.
  • The warranty in writing: who backs it, what it covers, what voids it, whether it transfers.

Red flags

  • A price with no length and no scope. You can't check it.
  • No mention of the deck on an RV with known leaks. The surprise comes later.
  • A sprayed roof with no stated thickness, or a promise to spray over wet or soft decking.
  • A "lifetime" warranty only spoken in the driveway. If it isn't on paper, it doesn't exist.

RV roof warranties, decoded

Three different companies can stand behind parts of the same roof, and none of them covers the others' work.

Our own RV coatings page puts it plainly: warranties are contractual obligations of a business, not proof of chemistry. A long warranty from a shop that closes is worth nothing, so weigh how long the installer has been around.
Who pays

Does insurance cover RV roof replacement?

Usually only when something sudden did the damage. Policies generally cover events like hail, a falling branch or a collision, and exclude gradual leaks, wear and deferred maintenance, which is what most roof leaks turn out to be. Your RV maker's warranty won't help either: Forest River's, for example, excludes leak damage from unmaintained seals.

If a storm or a low branch did it, photograph the roof and the interior before anything is repaired, get a written estimate that separates the storm damage from existing wear, and call your insurer before work starts. Some roof shops will prepare the estimate and photos in the format insurers ask for. Then read your own policy language; it's the only answer that counts.

ArmorThane applicators

A sprayed seamless roof from an ArmorThane applicator

If the math says replace and you're keeping the RV, a certified ArmorThane applicator can spray one of two systems at our 120-mil spec. The first is SureGrip polyurea under ArmorDeck Topcoat, which takes the UV. The second is ArmorFlex UV, an aliphatic polyurea that goes on alone because it doesn't need a topcoat. Aromatic polyureas chalk and change color in the sun, which is why the first system gets a topcoat (more on aromatic polyurea).

ArmorFlex UV's published numbers are 3,450 psi tensile strength and 730% elongation (ASTM D412), and 500 pli tear strength (ASTM D624-C). ArmorFlex UV and ArmorDeck Topcoat MAX both go tack-free in about an hour, so most roofs are done in a day or two. Each applicator sets their own price and writes their own warranty. Our RV roof coatings page covers roof-type prep and the full spec.

RV roof replacement cost FAQ

How much does it cost to replace an RV roof?

About $4,250–$9,200 for a 25- to 40-foot box at an independent shop or for a sprayed seamless roof, which is roughly $170–$230 per foot. Dealer service departments publish $7,000–$18,000. Add $1,500–$6,000 if the deck under the membrane is rotten.

How much does RV roof replacement cost per foot?

Sprayed seamless roofs sell for about $170–$210 per linear foot of box length, and one national network lists about $190 a foot with a $4,560 minimum. Two U.S. owner invoices for new membranes at independent shops work out to about $175 and $229 a foot. Measure the box from front cap to rear cap, not the brochure length, which includes a trailer's tongue.

How much does it cost to replace a camper roof?

The same per-foot math applies: a 25-foot travel trailer runs roughly $4,250–$5,750 at an independent shop or for a sprayed roof, before any deck repair. Short campers cost more per foot because shop minimums kick in; one sprayed-roof network's minimum is $4,560. A DIY TPO kit for a 20- to 25-foot camper is about $700–$780 in materials.

How much does RV roof repair cost?

Our 2026 estimates: $75–$200 in materials for a DIY sealant refresh, $300–$800 for a professional spot reseal, $1,000–$2,500 for a full professional reseal and $300–$900 for a patch or section repair. Rotted decking is the expensive part at $1,500–$6,000. Our RV roof repair guide shows how to find the actual leak first.

How much does an RV roof coating cost?

DIY roll-on coatings cost roughly $275–$570 in materials for a 30-foot roof, and a professional recoat runs $500–$3,000; both get redone every three to five years. A sprayed polyurea roof costs $170–$210 a foot and goes on at 120 mils, versus 30 to 40 mils for most parts-counter coatings.

Can I replace my RV roof myself?

Yes, if the deck is sound and you have a covered workspace and a helper. A complete TPO kit costs about $700–$900 for 23- to 42-foot roofs, and water-based adhesive covers about 160 sq ft per gallon. The hard parts are pulling and resetting the A/C and vents, fixing rot, and laying the membrane flat without stretching it.

Is it worth replacing the roof on an old RV?

It depends on how long you'll keep it and what it's worth. By our rule of thumb, a roof that costs more than about half the RV's value is hard to justify unless the RV is a full-time home. If you're selling within two years, reseal and disclose; a sprayed roof takes roughly a decade to beat a disciplined reseal routine.

How long does an RV roof last?

Our estimates: EPDM rubber 12–20 years with maintenance, TPO 10–20, PVC 15–20, and fiberglass and aluminum 20 or more. Lap sealant beads last about three to five years, so inspect the roof every three months. We expect a sprayed polyurea roof to last 20+ years; that's an expectation, not a warranty.

How long does it take to replace an RV roof?

A sprayed roof on a sound deck usually takes one to two days, and one national network quotes two to three. One shop quotes three to five days for a full replacement, one owner's re-roof took about a week and a half, and one dealer quoted three to four weeks. Rot repair adds time to all of them.

Does insurance cover RV roof replacement?

Usually only for sudden damage such as hail, a falling branch or a collision. Gradual leaks, wear and deferred maintenance are typically excluded, and RV maker warranties such as Forest River's exclude leak damage from unmaintained seals. Read your own policy, and photograph storm damage before anything is repaired.

Can you put a new rubber roof over the old one?

Not straight onto the old rubber. Dicor's installation guide allows a new substrate, such as lauan, over the old roof when tearing it off would cause structural damage, with the new membrane glued to that. A sprayed system can go over a sound, well-prepared existing membrane, but EPDM needs a bonding primer.

Is TPO or EPDM better for an RV roof replacement?

Both work and cost about the same to install; our estimates put EPDM at 12–20 years and TPO at 10–20. EPDM is the most common RV roof and chalks as it ages; TPO is white, smoother and heat-weldable. Pick the one your shop installs most often, and keep silicone off either one.

Why are dealer RV roof quotes so much higher?

Dealers publish $7,000–$18,000 for a tear-off, while independent shops and sprayed-roof applicators land around $170–$230 a foot. Dealer jobs can also mean long waits: one owner was quoted $15,000–$20,000 and three to four weeks. Get at least one independent or sprayed-roof quote to compare.
