Leak Problems

Water never announces itself on a camper. By the time you see a coffee-colored ring on the ceiling panel, the leak has usually been running for a season or two, and the real damage is in places you can't see: the plywood roof deck, the framing around the vent, the insulation batts wicking moisture sideways. This page walks through the failure modes we see most, and what fixing each one actually involves.

Failure #1: Lap sealant that quit

The self-leveling caulk around your vents, skylight, and antenna base has a working life of two to four years. Sun makes it brittle, movement cracks it, and the crack faces down where you'll never spot it from a ladder. This is the most common camper leak, and it is also the most fixable: DryCamp is detail-brushed over every flange and sealant line at heavy build, then the whole roof gets coated, burying the old sealant under a flexible membrane that doesn't have a working life measured in seasons.

Failure #2: Seam separation

Where the roof sheet meets the front cap, and along the termination bars at the gutter rails, two dissimilar materials are joined with fasteners and putty tape. Every highway mile flexes that joint. Once the putty tape compresses and cracks, wind-driven rain gets pushed straight into the wall cavity. Coating self-flashes over these transitions and stays elastic — 300%+ elongation — so the joint can keep moving without reopening a path for water.

Failure #3: Membrane oxidation and pinholes

An EPDM rubber roof left bare will chalk — that white streaking down your camper's sides is literally the roof washing away. As the membrane thins, it pinholes at stress points. A chalked roof needs a dedicated cleaner and primer before coating (this is not optional; coatings will not bond to chalk), and then the DryCamp topcoat rebuilds the weathering surface thicker than the factory ever made it.

Failure #4: Delamination and soft spots

Here is where we tell you the truth other coating companies won't: if your roof deck already has soft spots, coating alone will not fix it. The plywood is wet and possibly rotted. The honest sequence is: open the bad section, dry or replace the decking, then coat the entire roof so it never happens again. A coating over a spongy deck seals rot inside. Shops in our network can handle the deck repair; the membrane is your insurance that you only ever do that job once.

Climate reality check

Snow-country campers suffer freeze-thaw: water enters a hairline crack, freezes, and jacks the crack wider all winter. Sunbelt campers suffer UV: sealants and membranes simply cook. Coastal rigs get both salt and wind-driven rain. The DryCamp membrane is UV-stable, stays flexible below zero, and tolerates the ponding water that sits around AC curbs on an out-of-level roof. One product, engineered for the whole map — because campers move.
