TLDR
When a recoat and reseal is enough, when you need a full membrane replacement, and how the costs compare.
For most RVs, the answer is repair, as long as you catch it in time. A roof that is sound but aging usually needs a recoat and reseal, which is the least expensive roof work we do and the single best way to prevent a leak.
Ballpark cost from our price list
Ballpark ranges to help you plan, not a quote. Collision estimates are written after inspection. Final pricing comes from a written estimate after inspection. See full pricing.
Replacement becomes the right call when the membrane is torn, brittle, or past the point a sealant can save, or when water has already reached the wood underneath. At that point a recoat is throwing good money after bad.
The expensive scenario is the one that hides: a slow leak that rots the subfloor and walls turns a roof job into a restoration job. That is why an honest inspection matters. We will tell you which of the three you are actually looking at.
Bring it in and we will give you a straight recommendation and a written estimate, whether that is a reseal, a full membrane replacement, or water-damage restoration.
