- Regular treatment maintained
⚠ Risks:
- Rot at post bases
- Movement if ground fixings fail
Verdict: ⚠ Yes — but only with maintenance
❌ Pergolas You Should NOT Leave Up All Year
🚫 Cheap Fabric Canopy Pergolas
Why they fail:
- Fabric tears in wind
- Water pools and stretches material
- Frames often too lightweight
❌ Common winter damage:
- Bent frames

- Uplift in storms
Verdict: ❌ No — remove canopy or dismantle
🚫 Pop-Up or Event Pergolas
Designed for:
- Temporary use only
Not designed for:
- Wind
- Rain
- Frost
- Snow
Verdict: ❌ Never leave up long-term
🚫 Untreated Timber Pergolas

Verdict: ❌ No — unless upgraded and treated
🌬️ The Big Risk: Wind (Not Rain)
Most pergolas fail due to wind uplift, not rain.
Pergolas become wind sails when they have:
- Canopies
- Curtains
- Side screens
- Solid roofs
To reduce wind risk:
✔ Anchor every post
✔ Use concrete footings or rated ground screws
✔ Remove fabric roofs in winter
✔ Avoid lightweight frames in exposed gardens
🔧 What You Must Do If Leaving a Pergola Up All Year
✔ Proper Anchoring (Non-Negotiable)
- Concrete footings on soil
- Structural fixings into concrete or decking sub-frames
- No fixing into loose slabs
✔ Seasonal Checks
- Tighten bolts after storms
- Check for movement
- Clear leaves from gutters and roofs
✔ Winter Prep
- Remove fabric canopies
- Retract side curtains
- Check drainage paths
- Treat timber before winter
🧠 Quick Decision Guide
| Pergola Type | Leave Up All Year? |
|---|---|
| Aluminium frame | ✅ Yes |
| Louvered roof | ✅ Yes |
| Polycarbonate roof | ✅ Yes |
| Treated timber | ⚠ With care |
| Fabric canopy | ❌ No |
| Pop-up pergola | ❌ No |
🚨 Warning Signs You Should Act On
- Pergola rocks in wind

If you see these, don’t leave it standing through winter without fixing first.
✅ Final Honest Advice
A pergola left up all year must be treated like a permanent structure — not garden furniture.
If you want zero hassle:
- Choose aluminium
- Avoid fabric roofs
- Spend money on anchoring, not decoration
That’s the difference between a pergola that lasts 2 years and one that lasts 15+ years in the UK.
