Most RV roof failures we see in West Michigan show up on the first trip of the year. The rig sat through six months of freeze-thaw and snow load, the sealant cracked, water worked its way under the membrane, and the first highway run at sixty five miles an hour pulled the loose seam wide open. By the time the owner notices the ceiling stain at a campground in June, the decking underneath has already gone soft.
None of that has to happen. A thirty-minute spring inspection catches almost every RV roof problem before it becomes expensive. This is the checklist we run on every rig that comes through Platinum — and the same one Michigan owners can run themselves before pulling out of storage in May.
Before You Climb Up — Two Ground Checks
Most of what you need to know you can see without going up top. Walk around the rig before anything else and look for:
- ◆Black streaks running down the sidewalls. These are the calling card of a failing roof seam. Water tracks dirt and oxidized rubber down the walls every time it rains, leaving vertical black tide marks. The streaks point straight up to the leak source — follow them with your eye and you will land on the seam, vent, or seal that needs work.
- ◆Interior ceiling stains. Walk through the rig with the lights on. Look up. Stains near roof vents, the AC shroud, refrigerator vents, and the bedroom slide are the most common — those are the spots where the membrane is penetrated and the sealant is doing the actual waterproofing work. Any stain means water is already getting in.
On the Roof — Six Things to Inspect
If your RV roof is rated walkable, lay a piece of plywood across the rafters before stepping. If it is not — or if you do not know where the rafters are — work from a ladder leaning against the side and inspect across the surface with your eyes and a long-handled tool.
- ◆Self-leveling lap sealant on every roof penetration. Vents, AC shroud, antenna, refrigerator vent, plumbing vents, skylights — every one has a bead of self-leveling sealant around its base. Look for cracks, gray discoloration, gaps where the sealant has pulled back, and any spot where you can see metal or fiberglass through what should be a continuous bead. Sealant is consumable. On a Michigan rig, plan to re-bead every two to three years even if nothing else is wrong.
- ◆The front and rear roof seams. The two horizontal seams where the roof membrane meets the front and rear cap take the worst of the highway wind. They are the most common failure points on rigs older than ten years. Look for separated lap sealant, cracks running parallel to the seam, and lifted or buckled membrane near the corners.
- ◆Soft spots in the decking. Press the heel of your hand into the membrane every few feet — gently. Healthy decking is firm. A spot that gives, feels spongy, or sinks under pressure means water has already rotted the wood underneath. Mark every soft spot with painter's tape and photograph it. Soft spots are the dividing line between a reseal job and a deck repair.
- ◆AC shroud and vent covers for cracks. UV is brutal on plastic shrouds and vent covers. Cracks let water past the cover and onto the seal underneath. Look at every cover from above — sun-bleached white spots, visible cracks, and missing screws are all flags. A $25 vent cover replacement now beats a $1,500 ceiling repair in July.
- ◆Membrane condition across the field. Run your hand across an area between vents. Healthy EPDM feels like flexible rubber. Failing EPDM is brittle, crumbly, and leaves chalky residue on your palm. TPO that is failing tends to crack and split rather than chalk. Either way, what comes off on your hand is membrane that no longer protects the rig.
- ◆Standing water and pooling areas. A flat RV roof is supposed to drain. Note any spots where water collected over the winter — they will show as stained low-points on the membrane. Pooling does not just accelerate membrane wear. It also dumps water at the same seams every time it rains, multiplying the load on whatever sealant is in that low point.

Print this. Run it once a year before the first trip.
- Ground walk: black streaks on sidewalls, interior ceiling stains.
- Roof walk: sealant on every penetration, front and rear seams, soft spots, AC and vent covers, membrane condition, pooling areas.
- Photo log: photograph every flag with the date in frame. If you file an extended-warranty or insurance claim later, dated photos save the file.
- Sealant rule: in Michigan, plan to re-bead self-leveling lap sealant every two to three years even when nothing else is wrong. Sun and freeze-thaw consume it.
When Restoration Beats Replacement
Most dealerships quote a full RV roof replacement when an owner brings in a leaking rig — typically $7,000 to $15,000 depending on length and roof type. In most cases, the decking underneath is still sound and the failure is on the surface. That is what the Andek POLAROOF coating system was built for.
Restoration with Andek POLAROOF gets you:
- ◆A continuous, seamless waterproof membrane bonded to the existing roof — no seams, no fasteners, no laps that can fail.
- ◆A 20-year manufacturer warranty when applied per spec — the same Andek system that is on JFK Airport, NASA facilities, and the Pentagon.
- ◆Reflectivity that lowers interior temperature in the rig by ten to twenty degrees on a hot Michigan summer day. The white finish reflects roughly 85 percent of solar heat.
- ◆A fraction of the cost of a tear-off replacement, with zero downtime past the application window.
Restoration is not a fit for every rig. If the inspection turns up widespread soft spots, visible structural rot in the decking, or multiple failed prior coating layers, we tell you to replace and we do not bid the job. The whole value of a Platinum inspection is an honest call on which path the rig actually needs.
When to Stop Inspecting and Call
Three findings should pull you off the roof and onto the phone:
- ◆A soft spot you can feel through the membrane. Decking rot does not stop on its own and gets worse with every rain.
- ◆An active interior ceiling stain that is darker or wider than last fall. That means the leak grew through the winter — the membrane is no longer holding water back at all.
- ◆Membrane that comes off chalky or in pieces in your hand. The roof has reached end of service life and a routine reseal will not save it. This is restoration or replacement territory.
Frequently Asked Questions
When should I inspect my RV roof in Michigan?
Late April through mid-May is the right window. The rig has been sitting through the worst of the freeze-thaw cycle, snow has fully melted off the roof, and you can see what the winter actually did to the membrane and the sealant. You also want this done before the first big trip — most catastrophic RV roof failures show up on the first highway run after winter storage, when wind shear pulls at any seam that loosened up over the winter.
Should I climb on top of my RV to inspect it?
Only if the roof is rated for walking and you know how to spread your weight. Most rubber EPDM and TPO RV roofs are walkable but only across the rafters — stepping between rafters can crack the underlying decking. If you do not know where the rafters are, do the inspection from a ladder leaning against the side, looking across the roof surface. Or hire it out. We walk RV roofs for free in West Michigan as part of a moisture-mapping inspection.
What does failing RV roof sealant look like?
Healthy sealant is smooth, white or off-white, and continuous. Failing sealant looks gray, cracked, or chalky. You will see splits running across the bead, gaps where the sealant has pulled back from the metal it was bonded to, and sometimes black streaks running down the sides of the rig under the affected seam. Self-leveling lap sealant on RVs is consumable — it is supposed to be re-applied roughly every two to three years even with no other damage.
What is a soft spot on an RV roof and why does it matter?
A soft spot is a section of the roof that gives or sinks under your weight. It means water got past the membrane, soaked the wood decking underneath, and the decking is now rotted. Soft spots do not stop water from reaching the interior — they accelerate it. By the time you can feel the give underfoot, the leak has already been happening for at least one full season. Soft spots are also the dividing line between a routine reseal and a structural repair.
How do I know if I need restoration or full replacement?
Most RV roofs that get quoted for full replacement do not actually need one. The Andek POLAROOF coating system bonds to existing EPDM, TPO, fiberglass, and metal substrates and creates a seamless waterproof membrane with a 20-year warranty. Restoration works when the underlying decking is sound and the failure is in the membrane, sealant, or surface only. If the deck has widespread soft spots or visible structural rot, replacement is the right call. We tell owners straight which one their rig needs after the inspection.
