Choosing the Right Caravan Roof Hatch
Choosing the Right Caravan Roof Hatch
A caravan roof hatch can provide natural light and ventilation while making the interior of your caravan feel brighter and more comfortable. The right model depends on where the hatch will be installed, the existing roof opening and the features you want.
Start With the Roof Cut-Out Size
If you're replacing an existing caravan hatch or skylight, measure the opening in the caravan roof. Don't assume that the dimensions of the outside lid are the cut-out dimensions.
For example, our Ranger skylight range includes models designed for compatible 450 x 400 mm and 700 x 500 mm roof openings, while our smaller caravan toilet and bathroom hatch is designed for a 320 x 320 mm cut-out.
Check Your Caravan Roof Thickness
Roof thickness is another important measurement. A hatch needs to suit the thickness of the roof it is being installed into, particularly where an internal frame or trim needs to meet the external section correctly.
Think About Where the Hatch Will Be Installed
A larger caravan skylight can be a good option when natural light and ventilation are priorities in a living area. Bathrooms and shower areas may benefit from a smaller roof hatch designed to provide ventilation and help remove warm, humid air.
Consider the Features You Want
Depending on the model, caravan hatches and skylights may include features such as LED lighting, fly screens, block-out blinds, tinted glazing and different opening positions. Compare the individual product specifications rather than choosing by size alone.

Caravan Roof Hatch and Skylight Sizes
One of the most important things to check when buying a caravan roof hatch is the required roof cut-out. The cut-out measurement refers to the opening in the caravan roof and should not be confused with the overall dimensions of the hatch.
| Hatch Type | Cut-Out Size | Best Suited To | Key Features |
|---|---|---|---|
| Bathroom Roof Hatch | 320 x 320 mm | Caravan bathrooms, toilets and shower areas | Ventilation, extraction and LED lighting |
| Ranger Skylight | 450 x 400 mm | Living and general caravan areas | Double glazing, LED lighting, blind and fly screen |
| Large Ranger Skylight | 700 x 500 mm | Larger living areas where more natural light is wanted | Double glazing, LED lighting, blind and fly screen |
Important: Always check the specifications on the individual product page before ordering. Cut-out size, overall dimensions, roof thickness and available mounting space can all affect compatibility.
What to Check Before Buying a Caravan Hatch
What to Check Before Buying a Caravan Hatch
Replacing a caravan roof hatch isn't simply a matter of finding one that looks similar to the old unit. Take a few measurements and check the existing installation before ordering.
1. Measure the Roof Cut-Out
Measure the actual opening required in the caravan roof. The outside dimensions of the hatch or lid can be considerably larger than the cut-out, so don't use the external lid measurement as your only reference.
2. Check the Roof Thickness
Check the thickness of your caravan roof and compare it with the installation requirements shown on the product page.
3. Check Overall Clearance
Look at the space available around the proposed hatch position. Solar panels, air conditioners and other roof-mounted equipment may affect the space available for installation or opening the hatch.
4. Decide What Features You Need
Consider whether you want a simple ventilation hatch or additional features such as integrated LED lighting, a fly screen, block-out blind or double-glazed skylight.
5. Replacing a Complete Hatch or Just a Broken Part?
If the complete hatch is damaged or you're upgrading the existing unit, a new roof hatch or skylight may be the appropriate option. If the main hatch is still in good condition and only a strut, locking mechanism, fan or winding mechanism has failed, you may only need a replacement part.
For repairs to compatible existing hatches, browse our caravan hatch replacement parts rather than replacing the complete unit unnecessarily.
6. Consider Professional Installation
A roof opening needs to be correctly prepared, mounted and sealed to help prevent water ingress. If you're unsure about installation, sealing or electrical connections for a powered product, have the work carried out by a suitably qualified professional.
Caravan Roof Hatch FAQs
Caravan Roof Hatch FAQs
How do I know what size caravan roof hatch I need?
Start by measuring the roof cut-out required for the hatch. If you're replacing an existing unit, don't rely only on the outside dimensions of the lid. Compare the cut-out size, roof thickness and overall installation dimensions with the specifications of the new hatch.
What is the difference between a caravan roof hatch and a skylight?
The terms are sometimes used interchangeably. A caravan skylight generally places more emphasis on bringing natural light into the caravan, while a roof hatch may be primarily used for ventilation and access to fresh air. Many modern caravan skylights provide both light and ventilation.
Can I replace my caravan roof hatch with a different size?
Possibly, but changing the cut-out size can require modifications to the caravan roof. Replacing an existing hatch with a compatible model designed for the same cut-out is generally simpler. Seek professional advice if the roof opening needs to be altered.
What size roof hatch is suitable for a caravan bathroom?
This depends on the available roof opening and installation requirements. Our smaller bathroom and toilet roof hatch is designed for a 320 x 320 mm cut-out and provides ventilation and extraction for compatible installations.
Do caravan skylights provide ventilation?
Many opening caravan skylights do. Our Ranger skylights can be opened to provide airflow while also bringing natural light into the caravan. Check the individual model because features vary between hatches.
Can I buy replacement parts instead of replacing the complete hatch?
Yes, where compatible parts are available. If your existing hatch is otherwise in good condition, components such as struts, locking mechanisms, wind-up mechanisms or replacement fans may allow you to repair it without replacing the entire hatch.
Do caravan roof hatches have fly screens and blinds?
Some models do. Our Ranger 450 x 400 mm and 700 x 500 mm skylights include a fly screen and block-out blind, while features vary between other models. Check the individual product specifications before ordering.
Can I install a caravan roof hatch myself?
Installation requirements vary. Correct fitment and sealing are particularly important on a caravan roof to prevent water ingress. Electrical models may also require wiring. If you're not confident with the installation, use a suitably qualified professional.
