Quick Answer: A rooftop tent needs two numbers from your canopy: a dynamic rating above the tent's own weight (the only roof load you drive with — our hardshell tents weigh 85 kg) and a static rating above tent plus occupants (our 2.5 mm aluminium canopy is rated 300 kg static: 85 kg tent + 160 kg two adults + 20 kg bedding = 265 kg, leaving a 35 kg margin). Rule: match the thickness to the parked load, not the driving load — and get the rating in writing, with test evidence.
Every tent-canopy pairing question reduces to arithmetic, yet most "compatibility guides" stop at "make sure your roof is strong enough." This article shows the actual math — the same calculation our engineering team runs for every enquiry — so you can check any pairing, ours or a competitor's, in two minutes.
1. Dynamic vs static: the two numbers tents actually need
Dynamic load is what the roof carries while you drive. For a rooftop tent, that is the tent itself — nothing else rides up there in motion. Our hardshell tents weigh 85 kg; typical quality hardshells run in the 60–100 kg band. Any canopy or rack whose dynamic rating exceeds the tent weight is structurally fine for the highway.
Static load is what the roof carries when parked — tent plus people plus bedding. This is the number that decides your thickness, and the number almost nobody publishes honestly.
What to ask: for both ratings, in kg, and whether the static figure was tested. A rating without a test method is an estimate wearing a badge.
2. The parked math, worked
Here is the calculation for a couple in a 2.5 mm aluminium canopy:
| Load component | Weight |
|---|---|
| Hardshell rooftop tent (ours) | 85 kg |
| Two adults, inside the tent | 160 kg |
| Bedding, ladder, small gear | 20 kg |
| Parked static total | 265 kg |
| 2.5 mm canopy static rating | 300 kg |
| Margin | 35 kg |
The pairing passes — with margin to spare for a child or a cooler. Swap the canopy down to 2.0 mm aluminium (200 kg static) and the same night fails by 65 kg. That is the entire thickness decision, in one table.
If your tent is heavier than 85 kg or your crew is heavier than two adults, rerun the table — the method is the point, not our numbers.
3. The full rating ladder, so you can self-serve
| Canopy configuration | Static rating | Sleeps (85 kg tent) |
|---|---|---|
| Galvanized steel 1.5 mm | 150 kg | Tent + 1 adult, minimal gear |
| Aluminium 2.0 mm | 200 kg | Tent + 1 adult + gear |
| Aluminium 2.5 mm | 300 kg | Tent + 2 adults + gear (worked above) |
| Aluminium 3.0 mm | 500 kg (filmed test) | Family + full camp kit |
Our published ratings are static, graded by material and thickness, with a filmed test showing ten adults standing and jumping on a shell — because a rooftop tent with two people in it is a load you should be able to see proven, not pictured.
4. The roof rack question, if you're not mounting to the canopy
Mounting to a rack instead? The same math applies to the rack's ratings. Ours are published: 450 kg+ static, 250 kg+ dynamic. A rack also spreads load across crossbars, so check the bar spacing against your tent's mounting rails — a tent rated for a 1.2 m span sitting on 0.9 m bars is a fit problem, not a strength problem.
5. Three checks before any tent-canopy purchase
- Weigh your tent loaded. Manufacturer dry weight plus bedding and mounting hardware — the spec-sheet number is the floor, not the total.
- Get the static rating in writing. 300 kg "tested" beats 400 kg "estimated" every time.
- Check the parked worst case. The night it rains and everyone shelters in the tent is the load the structure must actually carry.

FAQ_SPLIT## Frequently Asked Questions
Can I mount a rooftop tent directly on a canopy, without a rack?
Yes, if the canopy has roof rails and a published static rating. Ours mount the tent to the canopy's own roof rails, rated 150–500 kg by configuration.
What if my tent weighs more than 85 kg?
Rerun the parked math with your real number. Every additional tent kilogram comes directly out of your occupant margin — on a 2.5 mm canopy, a 110 kg tent leaves just 10 kg of margin for two adults, and the honest answer becomes the 3.0 mm build.
Does driving with the tent damage the canopy?
Not if the dynamic rating exceeds the tent weight — the structure only sees the tent's 85 kg in motion. Torque-check the mounting bolts after the first corrugation run, the same advice as any roof-mounted accessory.
Is the static rating per side or total?
Total, across the roof. Uneven loading matters for comfort, but the rating itself — ours and anyone's honest one — is a whole-roof number.
