Pop-top roof: why we never wanted one, and what it really costs

A pop-up roof canvas lasts 8 to 12 years, and the first leaks occur between 5 and 8. Replacing the canvas costs £1,700 to £2,300 fitted. The temperature difference with a rigid wall in winter is 8 to 10 °C. Here are the three figures that matter, and no sales page highlights them.

We have never visited a single pop-up roof van. Not one. Never pushed the door of a workshop, never asked for a quote, never climbed onto a step to see the sleeping area up top. The category was dismissed before it was even opened, and yet it’s probably the equipment we get the most questions about.

So let’s put it this way: this is not an article from a disappointed owner. It’s an article about a decision we made without trying, about the two reasons that dictated it, and especially about what five years of living in a 1999 vehicle have taught us about the only thing that really matters here: what time does to the fabrics, seals, and plastics.

What a pop-up roof really solves

We need to start here because the promise is real, and we won’t pretend otherwise. A pop-up roof solves three problems at once, and no other equipment does that.

The first is the ceiling height. You can stand up in a vehicle that, with the hood closed, is no taller than a minivan. The second is the size when parked: an underground parking lot, a beach barrier, a ferry, a city center, all become accessible. The third is the sleeping area: the bed rises above the living space, so the floor space remains fully available for living, cooking, and working.

I understand this third point very well because it is exactly what our drop-down bed does on our Hymer B544: it lifts against the roof and frees up the entire floor. The difference is that a pop-up bed requires no canvas, no strut, and no frame seal.

How much it costs to install

This is the question everyone is asking, by far. When we look at what people are really searching for regarding pop-up roofs, the overwhelming majority of queries focus on the price, the installation cost, and the price by vehicle model. So let’s give the figures right away.

The market is dominated by two German manufacturers, Reimo and SCA, fitted under licence by workshops across Europe. In Britain they are joined by Skyline, which is the domestic option and the one most conversion firms quote first, and the fitting network is wide: SJ Campers, Base Campers, Knights, Clearcut, Vanscape and a long tail of regional converters all do this work week in, week out. That matters more than it sounds. A pop-top is not a part you buy, it is a hole someone cuts in your roof, and the value is in who cuts it.

And there’s one thing I haven’t found anywhere, despite serious research: the manufacturer’s warranty duration is not published by either manufacturer. Neither Reimo nor SCA displays it publicly. So I’m not going to pull a figure out of thin air to make it look good: if this is a criterion for you, it’s a question to ask in writing at the workshop before signing, and to have it written on the quote.

And how much it costs ten years later

Here’s the part that sales pages have no reason to highlight, yet it determines whether the deal is good or not. A pop-up roof is not a purchase; it’s a subscription.

Add it up. Over ten years, between annual maintenance, a set of seals, and a bellows at the end of its life, you come back to a figure close to the initial installation price. This is not a reason not to get one; it’s a reason to budget it as a recurring expense, just like what we describe in our maintenance cost report for a converted vehicle.

The cold, and why it’s my real reason

When I dismissed the pop-up roof, I had no figures. Just a buyer’s intuition: a canvas doesn’t insulate like a wall. The data I’ve found since is quite stark.

There are solutions, and they work: dedicated canvas insulators, with Velcro, that are placed inside the bellows, with seven-layer constructions including three layers of aluminum. They are sold, installed in five minutes, and take up a bit of space when stored. This is not a reason to exclude the pop-up roof; it’s an additional line in the budget and an extra operation in the evening routine.

And while we’re talking about the cold, we need to mention condensation because the subject is mechanically more tense under canvas than between two insulated walls: two people sleeping in a closed volume produce water, and this water has to go somewhere. This is the whole subject of our article on ventilation in vans and motorhomes, and it applies doubly here.

The wind, noise, rain

Again, honesty: I have never slept in a pop-up roof van, so I’m not going to tell you about a stormy night I haven’t experienced. What I can share are the benchmarks circulating among installers and owners.

You start to feel the movement at around 25 mph of wind, and it turns into felt instability nearer 40 mph. These are not danger thresholds; they are sleep thresholds: from there, it slams, it moves, and you sleep poorly. On a rigid wall, you hear the rain on the roof, and that’s it; under a canvas, you’re in a drum.

What has changed, and you see it on any campsite, is the quality of the canvases. They are much stronger than in my early days, and some are now inflatable on the sides, which stiffens the whole structure and precisely reduces this flapping. Two geometries share the market: the triangular roof, where one side lifts, and the square roof, where the entire roof rises horizontally.

What our roof lights have taught us

This is the only area where I have real legitimacy, and it’s probably the most useful part of this article. On Édouard, both roof lights have been changed, the one in the bathroom and the one in the kitchen. And the one in the kitchen is already due for a second replacement.

The cause, I know and I own it: they are low-quality roof lights. We never replaced them with quality roof lights. Next time, we might go for something really good.

And this is where the hinge turns in my mind, word for word: it’s scary to think about a pop-up roof when you see what happens to a simple roof light. A roof light is a frame, a seal, a plastic, and a crank. If it fails twice in five years, what happens to a canvas bellows of several square meters, with zippers, seams, and a moving mechanism?

What I have never seen, and what matters

I need to tell you something because it’s what separates me from articles that list the disadvantages of a pop-up roof: I have never seen a pop-up roof in poor condition. Not a moldy canvas, not a bellows repaired with tape, not someone struggling to close it in the rain. And we have been parked next to them, on aires and campsites, for years.

This does not mean it doesn’t happen; the figures for bellows replacement exist for a reason. It means two things. One, people who put five or six thousand into a roof tend to look after it. Two, when you read an article describing failures in the present tense, ask yourself if the author has seen them or if they have compiled them. I tell you what I have seen, and I tell you what I have not seen.

Why we never see them on a motorhome

This is a question we are often asked, and I can answer it from the inside. When we were looking for our vehicle in 2020 and 2021, we found pop-up roof vans, and hardly any campers. Today, companies know how to install pop-up roofs on vans; it has become common. But I still have not seen a single motorhome with a pop-up roof. It’s just vans and campers, period.

The reason is structural. A motorhome already has its ceiling height, so it has nothing to gain in terms of standing comfort. It also has nothing to gain in terms of size because a six-meter integral won’t fit in an underground parking lot anyway. And it has a lot to lose: cutting the roof of a monocoque polyester cell opens a waterproofing wound in the only part of the vehicle that we spend our lives protecting. The risk-benefit ratio simply does not exist. It’s also a real issue of payload, and on an older motorhome, the question of size and dimensions is resolved at the time of purchase, not afterward.

What we chose instead, and the fear that did not materialize

What I was looking for at the time was not even a pop-up roof. It was a U-shaped lounge at the back with a pop-up bed that descends low enough. Definitely not a pop-up bed at the front like those of Hymer, because I was afraid of getting too hot, up high, under the ceiling.

We took Édouard anyway, with exactly the pop-up bed at the front that I dreaded. And the fear never materialized. We didn’t get too hot. Sometimes warm, yes, but not that much, and not that often.

I’m telling you this because it’s the real moral of this pop-up roof story. Buyer’s fears are not all equal. The one about heat at height was false; usage disproved it in three weeks. The one about winter under a canvas is confirmed by everything I’ve read since. The difference between the two is that one is about a feeling, and the other is about physics.

And the height, then?

Since it’s the number one argument for the pop-up roof, let’s say what it really costs to drive high. Édouard is three metres, which the British bridge and barrier signs will show you as 9 feet 10. Not particularly tall for a motorhome, but not particularly small either. Concretely, this means: some inaccessible parking lots, and impassable bridges, but that’s rare.

Our method is to read the signs. No heavy vehicle GPS, no dedicated app, just the habit of looking up at the entrance of a structure. In five years, that has been enough. If you are hesitating over five thousand pounds to gain a metre of headroom, start by counting how many times, on your last trip, the height actually blocked you.
