The honest answer: it depends on how much rot is under the membrane, and nobody can quote it accurately without looking. Industry-wide, a full RV roof replacement at a shop commonly runs several thousand dollars - often in the $5,000-$15,000 range depending on the rig's length and damage - while a reseal or partial repair can be a fraction of that. What I can do is show you exactly what drives the number, so you can spot a fair quote from a padded one.
What you're actually paying for
An RV roof isn't one layer - it's a system. A real rebuild involves:
- Tear-off. Removing the old membrane, vents, skylights, AC unit, and every fixture.
- Decking. This is the wild card. If the plywood or luan underneath is rotted, it gets replaced - and rot loves to spread farther than it looks from inside.
- Framing. In bad cases, water has gotten into the roof trusses themselves.
- New surface. New membrane or coating, new sealant at every penetration, everything remounted.
The difference between a $4,000 job and a $12,000 job is almost always item 2 and 3 - how deep the water got before someone stopped it.
Why quotes vary so much between shops
- Roof length. Many shops price by the linear foot, so a 35-foot fifth wheel costs more than an 18-foot travel trailer.
- What they find. A quote given before tear-off is a guess. Ask any shop how they handle surprise rot - that conversation tells you a lot.
- What goes back on. Reusing a tired AC gasket and old vents is cheaper today and leakier next year.
- The finish. A standard membrane restarts the reseal-every-year clock. A seamless coating system like Crazy Seal costs more up front but is designed to be one-and-done, with a 50-year product warranty from the manufacturer.
Repair, reseal, or rebuild?
Not every leaky roof needs a rebuild, and I'll tell you if yours doesn't. Rough guide:
- Cracked sealant, solid decking → reseal. Cheapest fix, do it now.
- Small tear or a couple of soft spots → sectional repair may hold.
- Widespread soft decking, stains in multiple rooms, chalking membrane → rebuild. Patching it wastes money.
The "better than factory" part
I'm a perfectionist about roofs because roofs are where campers die. When we rebuild one at our Roscoe shop, the goal isn't to get it back to factory - factory is a stapled membrane and a bead of lap sealant. The goal is better than factory: solid decking, properly sealed penetrations, and if you choose, a seamless Crazy Seal membrane over the whole thing.
Roof cost FAQ
Can you quote me over the phone? A range, yes. A real number needs eyes on the roof - send photos to start, or bring it by the shop.
Will insurance cover it? Sudden damage (hail, a tree limb) often yes; slow leaks and neglect usually no. We can document damage for your claim.
Is a roof rebuild worth it on an older camper? Often yes - a solid older rig with a new roof beats payments on a new one. We'll give you a straight opinion either way.
