RV roof replacement runs about $300 to $325 per linear foot installed, so a 30 foot rig lands near $9,000 to $9,750 and a 40 foot rig tops $12,000. Membrane only jobs on smaller campers start closer to $3,000. The single biggest swing is whether the crew simply recovers the roof with new membrane or has to tear out rotted decking underneath first. This guide gives the per foot math for your own length, the real cost by material, and a clear line for when a repair or a recoat beats a full replacement.
How much does RV roof replacement cost in 2026?
A full RV roof replacement typically costs $3,000 to $12,000 in 2026, driven by rig length, membrane type, and how much of the wood decking has to be replaced. Professional shops price the job at roughly $300 to $325 per linear foot for a standard rubber membrane recover, which already covers tear off, new membrane, sealant, and reflashing all roof penetrations.
RV roofs are about 8.5 feet wide, so square footage is close to your length times 8.5. A 30 foot travel trailer carries roughly 255 square feet of roof. Use the table below to estimate by length before you call a shop.
| RV length | Approx. roof area | Membrane recover (installed) | Full replace with decking repair |
|---|---|---|---|
| 20 ft | ~170 sq ft | $3,000 to $6,500 | $5,000 to $9,000 |
| 30 ft | ~255 sq ft | $4,500 to $9,750 | $7,500 to $13,000 |
| 40 ft | ~340 sq ft | $6,000 to $13,000 | $10,000 to $18,000 |
Materials alone are a smaller share than most owners expect. A rubber membrane kit for a 30 foot rig costs $800 to $1,800, and labor at $95 to $150 per hour over 20 to 40 hours is what pushes the installed total up. For the underlying material pricing on rubber systems, see our EPDM roofing cost breakdown.
What drives the price of an RV roof replacement?
Six factors move an RV roof quote, and length is only the first. Knowing which ones apply to your rig tells you whether you are looking at the low end or the high end of the range above.
- Length and layout. More linear feet means more membrane, more sealant, and more hours. Slide out roofs, awnings, and multiple AC units add labor.
- Membrane type. EPDM rubber is the cheapest, TPO sits in the middle, and one piece fiberglass or PVC is the most expensive by a wide margin.
- Decking condition. This is the wildcard. If water has rotted the plywood or luan under the old membrane, the crew replaces framing and decking before any new roof goes on, often adding $1,500 to $5,000.
- Recover vs full tear down. A membrane recover keeps the deck and swaps only the top layer. A full replacement opens the roof structure. The two can differ by more than double.
- Roof mounted equipment. Every AC shroud, vent, antenna, and skylight has to be removed, resealed, and reset, which adds hours whether or not the equipment itself is replaced.
- Shop rate and region. Mobile RV techs and coastal metros charge at the top of the $75 to $150 per hour band, rural shops at the bottom.
RV roof materials compared: EPDM, TPO, fiberglass, and aluminum
Four materials cover almost every RV roof: EPDM rubber, TPO, fiberglass, and aluminum. They differ in installed cost, lifespan, and whether they can be walked on or recoated later. Match the material to how long you plan to keep the rig.
| Material | Installed cost (30 ft rig) | Typical lifespan | Notes |
|---|---|---|---|
| EPDM rubber | $3,000 to $8,000 | 10 to 15 years | Cheapest, flexible, needs periodic Dicor lap sealant upkeep. Common OEM membrane. |
| TPO | $4,000 to $9,000 | 12 to 20 years | Heat welded seams, more puncture and UV resistant than EPDM, reflective white surface. |
| Fiberglass (one piece) | $6,000 to $15,000 | 20 to 30 years | Rigid, walkable, near zero seam leaks, heaviest and priciest option. |
| Aluminum | $5,000 to $12,000 | 20 plus years | Durable and recyclable, mostly on older or high end coaches, can dent and drum in rain. |
Membrane brands you will see quoted include Dicor and Alpha Systems for EPDM and TPO. If you are weighing rubber against other systems generally, our guide to roof coating materials and what each bonds to explains which surfaces accept a recoat later.
Repair, recoat, or replace: which does your roof actually need?
Not every failing RV roof needs a full replacement. Isolated leaks call for a repair, a chalky or lightly cracked membrane with a sound deck calls for a recoat, and only widespread membrane failure or soft decking calls for replacement. Matching the fix to the damage can save several thousand dollars.
| Condition | Right fix | Ballpark cost |
|---|---|---|
| One or two leaks, seams lifting | Spot repair with EternaBond tape and lap sealant | $100 to $1,500 |
| Aged but intact membrane, firm deck | Liquid or spray recoat (RV Armor, FlexArmor) | $2,000 to $5,000 |
| Cracked, shrinking, or torn membrane | Membrane recover | $3,000 to $9,750 |
| Soft spongy roof, visible rot | Full replacement with decking repair | $7,500 to $18,000 |
The soft spot test is the fastest gut check: press across the roof, and any area that flexes or feels spongy means water has reached the decking and a recoat will not save it. For targeted fixes short of replacement, walk through our RV roof repair guide. To stretch the life of a sound roof and delay replacement, follow a regular RV roof maintenance schedule.
DIY vs professional RV roof replacement
DIY membrane replacement can cut the cost by half or more, but it carries real risk on any roof with hidden rot or heat welded TPO seams. Budget for materials plus tools if you go it alone, and be honest about whether you can reset AC units and reseal penetrations watertight.
| Path | Cost (30 ft rig) | Time | Best when |
|---|---|---|---|
| DIY EPDM recover | $1,000 to $2,500 in materials | 2 to 4 days | Sound deck, EPDM membrane, comfortable on ladders and with adhesives |
| Professional recover | $4,500 to $9,750 | 1 to 3 days | Want a workmanship warranty, or TPO or fiberglass involved |
| Professional full replace | $7,500 to $18,000 | 3 to 5 days | Rotted decking or structural repair needed |
TPO seams are heat welded and fiberglass is a bonded one piece system, so both are poor DIY candidates. Rotted decking is another stop sign, because getting the framing and moisture barrier right is what keeps the next roof from failing early.
How an RV roof gets replaced, step by step
A professional RV roof replacement follows the same sequence whether it is a recover or a full tear down. Understanding the order helps you read a quote and spot a shop that skips steps.
- Strip the roof. Remove AC units, vents, antennas, fans, and the rooftop railing, then peel the old membrane back to the deck.
- Inspect and repair decking. Probe for soft spots. Cut out and replace any rotted plywood or luan and treat or replace wet framing.
- Prep the surface. Clean and dry the deck, then lay any new insulation or moisture barrier the system calls for.
- Install the membrane. Roll adhesive, set the EPDM or TPO sheet, work out bubbles, and trim to the edges. TPO seams get heat welded.
- Reset and reseal penetrations. Reinstall AC units, vents, and fixtures, then seal every edge and penetration with self leveling lap sealant.
- Final inspection. Check every seam and termination, water test if possible, and confirm no ponding at the edges.
How long does it take and how long will it last?
A professional RV roof replacement takes 1 to 5 days: 1 to 3 days for a straightforward membrane recover and 3 to 5 days when decking repair is involved. Total skilled labor usually runs 20 to 40 hours. Lifespan then depends on the material you chose, from about 10 to 15 years for EPDM to 20 to 30 years for fiberglass.
Regular resealing extends any of these numbers. RV membranes fail at the seams and penetrations long before the field of the roof wears out, so annual inspection and lap sealant touch ups are what push a rubber roof to the top of its range.
Does insurance cover RV roof replacement?
RV insurance may cover roof replacement when the damage comes from a sudden covered event like a hailstorm, a fallen branch, or a collision, but it generally will not pay for gradual wear, dry rot, or delamination. Comprehensive coverage is the part of an RV policy that applies to storm and impact damage.
Coverage depends on your policy, deductible, and the cause of loss, so document the damage with photos and dates and file promptly. Claims tied to age or neglected maintenance are commonly denied, which is one more reason a maintenance log matters.

Frequently asked questions
How much does it cost to replace an RV roof?
Most RV roof replacements cost $3,000 to $12,000 in 2026, or about $300 to $325 per linear foot installed. A 30 foot rig commonly lands near $9,000 for a rubber membrane recover, while a full replacement that includes rotted decking repair can reach $13,000 to $18,000 on a larger coach. Materials are a small share; labor at $95 to $150 per hour drives the total.
Can you replace an RV roof yourself?
You can DIY an EPDM rubber recover if the decking is sound, cutting the cost to $1,000 to $2,500 in materials over 2 to 4 days. DIY is not advisable for TPO, which needs heat welded seams, or fiberglass, which is a bonded one piece system. Hidden rot is the biggest reason to hand the job to a professional shop.
How long does an RV roof last?
An RV roof lasts about 10 to 15 years for EPDM rubber, 12 to 20 years for TPO, and 20 to 30 years for fiberglass or aluminum. Actual life depends heavily on upkeep, since seams and penetrations fail first. Annual inspection and resealing with self leveling lap sealant can push a rubber roof to the top of its range.
How long does it take to replace an RV roof?
A professional RV roof replacement takes 1 to 3 days for a straightforward membrane recover and 3 to 5 days when decking has to be repaired, totaling roughly 20 to 40 hours of skilled labor. A DIY EPDM recover typically spans 2 to 4 days depending on weather and how many rooftop fixtures must be removed and resealed.
What is the best material for an RV roof?
TPO is the best all around choice for most RVs, balancing cost, a 12 to 20 year lifespan, and strong puncture and UV resistance with a reflective surface. EPDM rubber is cheapest but shorter lived, while fiberglass lasts longest at 20 to 30 years and is walkable, though it costs the most and adds weight.
Should I repair or replace my RV roof?
Repair when leaks are isolated and the decking is firm, recoat when an aged membrane is still intact, and replace only when the membrane has widespread cracking or the roof feels soft underfoot. The soft spot test decides it: any area that flexes means water reached the deck and a full replacement, not a patch, is needed.
