RV Water Damage Repair

Most owners call us after the water is already in. That’s normal, and fixable. We check what shows and what hides, then give you a repair plan. We come to your trailer or motorhome at the driveway, seasonal site, or storage lot.

What are the signs of RV water damage?

Water damage shows up in stages:

  • Brown or yellow ceiling stains, especially rings
  • Musty smell inside cabinets or after rain
  • Soft spots when walking the roof
  • Sagging ceiling panels or bubbled wallpaper
  • Delaminating sidewalls near the roofline
  • Screws that no longer bite near roof edges

Can a small roof leak really cause thousands in damage?

Yes. A pinhole at a vent flange lets in a little water every time it rains. Over a season it soaks the luan decking (the thin plywood under the roof), then the insulation, then the framing. None of it shows inside until the ceiling stains, and by then the repair is structural. A tube of sealant in the fall is the cheapest water damage repair there is.

Why is my fiberglass sidewall bubbling?

Bubbles or waves in a fiberglass (fibreglass) sidewall near the roofline are usually water, not sun. Moisture gets behind the outer skin from a roof edge or window seam, the glue lets go, and the skin pulls away from the wall. That’s delamination, and it spreads with every freeze-thaw cycle. We trace the entry, meter the wall, and tell you plainly whether it’s a stop-the-water job or a rebuild.

What a water damage assessment measures

The stain shows where the water ended up, not where it is now. We take moisture readings across ceilings, walls, and floors to find the wet area past the stain. We probe the sheathing and framing to tell a cosmetic soft spot from a structural one. We also check the insulation, which can hold water long after surfaces feel dry.

What repair looks like at each stage

Caught early, with staining but sound structure, the job is sealing the entry, drying the cavity, and fixing the panels. Caught mid-stage, soft sheathing gets cut out and replaced, wet insulation comes out, and the framing is checked before anything closes. Caught late, it becomes a structural rebuild, and sometimes a full roof replacement is the more honest spend. We tell you which stage you’re at and price the stage, not the fear.

Drying comes before closing

A common mistake is closing up a cavity that’s still wet. It rots behind the new panel and the job gets done twice. We dry the structure and check it with a meter before insulation and panels go back in. That drying time is in the schedule on purpose.

Does insurance cover RV water damage?

It depends on your policy and on how the water got in. Sudden events such as a storm, hail, or a fallen branch are the claims insurers most often consider. Gradual seepage from failed sealant is usually treated as maintenance, and many policies exclude it. We do not decide coverage and never promise it. If you need documentation, we provide dated photos, written notes, and repair estimates. Your adjuster gets evidence, not a guess.

How much does RV water damage repair cost in Ontario?

There’s no flat rate, and a price given before anyone sees the roof is a guess. Final pricing depends on roof size, roof condition, prep requirements, travel, access, visible damage, and hidden damage found during inspection. So we start from photos or an inspection.

What moves the price of an RV roof job
FactorWhy it moves the price
Roof sizeMore surface is more material and more labour
Roof conditionChalking, failed sealant, and prior repairs add prep
Prep requiredPrep is most of the job; removal and cleaning vary widely
Travel and accessDistance, site access, and setup affect the visit
Visible damageRepairs found up front are scoped into the estimate
Hidden damageWhat the inspection uncovers below the surface

You see the full estimate before any work begins. Nothing gets done that you haven’t approved, and the number doesn’t change without your say-so.

Keep the water outside your RV.

Request an estimate, send photos of your roof, or call and text with questions. If the leak source is unclear, an inspection is the right first step.
