Pop-Top vs Fixed High-Top: Which Roof Is Best?

Why the Roof Choice Matters

The roof is one of the most significant decisions in any campervan conversion, both financially and practically. Standard-roof panel vans typically have an internal height of approximately 1.3–1.4m — comfortable for sitting, impossible for standing. Any conversion intended for regular use almost always includes some kind of roof upgrade.

There are two main aftermarket options: a **pop-top (elevating) roof** or a **fixed high-top**. Neither is objectively better — the right choice depends on how you plan to use the van.

Pop-Top Roofs

A pop-top roof hinges up to create additional headroom and, in most designs, an additional sleeping berth above the main living level. When closed, the van returns to its original height profile.

**Popular UK pop-top brands:**

**EasiFit** — UK-manufactured, widely used by independent converters; good reputation for build quality

**SCA** — another UK option, popular for VW-based builds

**Kiravans** — VW T6/T5 specialists; well-regarded in the VW converter community

**Cost:** A pop-top adds approximately **£2,500–£4,500** to the conversion cost, including fitting. The variation reflects quality differences between suppliers and the complexity of fitting to different base vehicles.

**When raised:** provides full standing height (typically 1.85–2.0m depending on design and van), and the upper berth can sleep one or two adults on a canvas-supported sleeping platform.

**When closed, approximate heights:**

VW T6 with pop-top closed: approximately **1.96–2.00m** overall vehicle height

This passes under most UK height barriers (typically 2.0m or 2.1m in car parks)

Ferry "high vehicle" surcharges: typically triggered above 1.85–1.90m — a closed pop-top is a borderline call and varies by ferry operator

### Pop-Top Advantages

**Low profile when closed** — better aerodynamics means improved fuel economy; fits in more parking structures; more discreet for stealth camping

**Additional sleeping berth** — the elevated sleeping platform can sleep one or two people, making pop-tops popular for families or those who travel with guests

**Ferry charges** — some operators don't classify closed pop-tops as high vehicles, saving on crossing costs

**Lower cost than some alternatives** — cheaper than a bespoke GRP high-top on some platforms

### Pop-Top Disadvantages

**Seal deterioration over time** — the canvas or fabric seal between the roof and the van body degrades. Replacement typically costs **£150–£400** and is needed every 5–8 years depending on use and conditions

**Not as well insulated as a fixed roof** — even with insulated lining panels in the canvas, a pop-top loses more heat than a solid roof. In cold weather this is noticeable.

**Noise in wind and rain** — canvas pops are louder in heavy rain than a solid roof, and can be draughty in high winds

**Must be closed while driving** — unlike a fixed roof, the pop-top cannot be in use while moving. This is usually obvious, but occasionally inconvenient.

**Moving parts** — any mechanism can fail. The struts and hinges require occasional maintenance.

Fixed High-Top Roofs

A fixed high-top replaces the van's standard roof panel with a custom fibreglass or GRP (glass-reinforced plastic) shell that permanently raises the vehicle's roofline.

**Cost:** A custom GRP high-top typically adds **£2,000–£3,500** to the conversion, depending on the van platform and the complexity of the design.

**Typical height increase:** 25–40cm above the original roofline, bringing internal standing height to approximately **1.85–2.0m** depending on the van. Overall vehicle height is typically **2.4–2.6m**.

### Fixed High-Top Advantages

**Superior insulation** — a solid GRP shell can be insulated to the same standard as the van walls and floor. Much better thermal performance than a pop-top canvas.

**No moving parts** — nothing to fail, reseal, or maintain beyond normal bodywork care

**Quieter and warmer** — solid roof performs better in rain, wind, and cold weather than any pop-top canvas

**Always available** — standing height is accessible at all times without any setup

### Fixed High-Top Disadvantages

**Permanently raises vehicle height** — at 2.4–2.6m, the van will not pass under car park barriers rated at 2.0m or 2.1m. This is a significant practical consideration if you park in multi-storey car parks frequently.

**Ferry "high vehicle" surcharges** — a fixed high-top almost always triggers high vehicle pricing from ferry operators. This can add **£30–£100 per crossing** depending on the route.

**Less discreet** — a custom high-top makes the van obviously a campervan. This reduces stealth camping options and can affect resale in some markets.

**No additional sleeping berth** — unlike a pop-top, a fixed high-top provides headroom but no extra sleeping space above the main level.

Factory High Roofs: A Third Option

On some platforms, a high roof is available from the factory and avoids the need for any aftermarket modification:

**Mercedes Sprinter H2 and H3** — genuine standing height from the factory at no aftermarket cost

**Ford Transit H2** — similar

**VW Crafter H2** — available but not as common in campervan builds as the Sprinter equivalent

**VW T6** — VW does **not** offer a factory high roof option on the T6 range. Your only options are an aftermarket pop-top or a custom high-top. This is one of the genuine limitations of the T6 platform for taller owners.

Key Practical Factors

**Car parks:** The majority of UK car parks with height barriers are set at 2.0m or 2.1m. A standard van or closed pop-top passes; a fixed high-top typically does not. If you regularly use multi-storey car parks for work or shopping, this is a significant factor.

**Campsites:** Most UK campsites do not impose height restrictions that would affect either option. 3m is a common maximum height — both options are well below this.

**Ferries:** Check the specific operator. Most trigger high vehicle rates above 1.85–1.90m. A closed pop-top is often below this threshold; a fixed high-top is above it.

**Fuel economy:** A higher vehicle profile creates more aerodynamic drag and increases fuel consumption at motorway speeds. The difference between a standard roof and a closed pop-top is minor; a fixed high-top has a more noticeable effect, particularly above 60mph.

The Bottom Line

Choose a **pop-top** if: you value the additional sleeping berth, you park frequently in height-limited spaces, you want better fuel economy and stealth, or you use ferries regularly. Budget for seal replacement every 5–8 years.

Choose a **fixed high-top** if: you want a warmer, quieter, lower-maintenance roof, you don't park in height-limited spaces, and you don't need the extra sleeping berth. Check ferry costs for your typical crossings.
