Can You Use a Barbecue Under a Pergola? Grilling Guide for Safe Outdoor Cooking

Thinking of flipping burgers while shaded under your aluminium pergola? The short answer is yes—you can barbecue under a pergola, especially aluminium ones—but there’s a sizzling list of safety rules to follow. From fire hazards to smoke traps, grilling under cover calls for smart setup. Here’s how to get it right without roasting your rafters.

The Desire for Sheltered Outdoor Cooking

The classic British barbecue is often a game of weather roulette.

You set the table, light the grill—and then the skies open. A pergola feels like a dream solution. It adds shade, a touch of elegance, and most importantly, shelter when the heavens inevitably decide to join the party.

So it’s no wonder many are tempted to roll the BBQ underneath and carry on sizzling. But there’s more to it than just staying dry.

Understanding the Risks (Fire, smoke, heat damage)

A pergola isn’t just a pretty frame—it’s a structure, often made from materials that don’t love open flames.

From the moment you strike a match, you're dealing with heat, smoke, and grease. These elements can easily damage your pergola or worse—cause a fire. Being aware of the risks is the first step to grilling with confidence.

Assessing the Risks: Pergola Material and BBQ Type

Fire Hazards and Flammable Materials

Every pergola is different, and the material it’s made from plays a big role in how safely you can grill underneath.

Wood Pergolas: High Risk (Sparks, radiant heat)

Wood looks beautiful, but it doesn’t handle heat well.

A stray spark from your charcoal BBQ or a sudden flare-up could leave more than just scorch marks. If you’re using a wooden pergola, you’ll need added fire protection—think heat shields and generous clearance.

Aluminium Pergolas: More Heat Resistant, but Still Considerations

Aluminium pergolas are a better choice for BBQ setups.

They don’t catch fire easily, and they handle heat better than timber. Still, be cautious. Extended exposure to heat can discolour the frame, and nearby decorative elements like string lights or curtains can still pose a risk.

Fabric Canopies/Curtains: Extreme Flammability Risk

Let’s be blunt—fabric and fire do not mix.

If your pergola has flowing curtains or a canvas roof, keep the BBQ well away. Even heat radiating upward can be enough to start a fire. Roll back or remove any fabric elements before you light up.

Smoke and Ventilation

Carbon Monoxide Risk (Especially with charcoal/gas)

Charcoal and gas grills produce carbon monoxide—an invisible, odourless gas that can be deadly in enclosed or poorly ventilated spaces.

Even though a pergola isn’t technically enclosed, it can still trap fumes if it has limited airflow. That’s why positioning and design matter.

Ensuring Adequate Airflow for Smoke Escape

Grilling under cover works best when air can move freely.

Choose pergolas with open sides or roofs that open up, like louvred aluminium models. These allow smoke to escape, keeping the air clean and reducing that smoke-in-the-eyes barbecue effect.

Heat Damage to the Pergola Structure (Discolouration, warping)

Heat doesn't just rise—it lingers.

If your BBQ is too close to the roof or support beams, the heat could cause discolouration or even warping over time. Metal may tolerate flames better than wood, but it's not immune to long-term wear.

Best Practices for Safe Barbecuing Under a Pergola

Positioning Your Barbecue Safely

Maintaining Adequate Clearance from all Pergola Components

This one’s simple: distance is your best friend.

Make sure your barbecue is set back from posts, beams, and any overhead elements. As a rule of thumb, allow at least 60 cm (2 feet) of clearance for gas grills and even more for charcoal.

Placing BBQ on a Non-Combustible Surface

Don’t even think about putting a BBQ directly on decking or artificial grass.

Use a fireproof base—stone, concrete, or heat-resistant tiles work brilliantly. This stops heat damage and reduces fire risk if something drops or spills.

Ventilation Strategies

Open-Sided Pergolas and Louvered Roofs (Optimal)

The more open your pergola, the better the airflow.

Louvred roofs are ideal—they let you adjust how much cover you have while still allowing smoke and heat to escape. Open-sided designs work best to keep things breezy.

Avoiding Fully Enclosed Spaces

Enclosed pergolas or those with glass panels trap heat and smoke, turning your BBQ into a chimney-less oven.

Keep at least two, if not all four, sides open to let fresh air in and smoke out.

Barbecue Type Considerations

Charcoal Grills: Highest Risk, Maximum Caution

Charcoal gives unbeatable flavour—but it’s messy, smoky, and unpredictable.

It burns hotter, throws more sparks, and produces more carbon monoxide. If you're using charcoal under a pergola, be extra cautious with placement and ventilation.

Gas Grills: Easier to Control, but Still Open Flame

Gas grills are cleaner and easier to control, but don’t be fooled—they still have open flames and can flare up without warning.

Keep an eye on gas connections and check for leaks before lighting up.

Electric Grills: Lower Risk, but Heat Still a Factor

Electric grills are the safest bet under a pergola. No flame, less smoke—but still hot enough to cause damage if placed carelessly.

Even with electric, clearance and surface still matter.

Essential Safety Equipment and Habits

Fire Extinguisher or Water Source Nearby

Whether you’re a casual griller or a weekend pitmaster, always have a fire extinguisher or hose close by. It’s one of those things you’ll never regret having if you need it.

Never Leave BBQ Unattended

We’ve all wandered off to get the burger buns—but unattended barbecues are the biggest cause of garden fires.

Stay close and stay alert.

Keeping Children and Pets Away

Create a buffer zone around your BBQ—no children, no dogs, no distractions.

Set clear boundaries, and make it a rule that little feet and paws stay well clear.

Proper Ash Disposal (For charcoal)

Charcoal stays hot long after the fire's out.

Dispose of ash in a metal bucket and only after it’s fully cooled. Never pour it onto soil or into the bin while warm.

Pergola Features That Enhance BBQ Safety

Retractable or Adjustable Louvred Roofs (For open-air cooking)

Roof open, grill on.

A retractable roof is your secret weapon—shelter when needed, ventilation when you’re cooking. Aluminium louvres are particularly great as they resist heat and can be easily adjusted.

Integrated Exhaust Fans (For dedicated outdoor kitchens)

If you’re going full gourmet with an outdoor kitchen, consider a ceiling fan or extractor.

It helps manage smoke and keeps your pergola fresh and safe during longer cooking sessions.

Non-Combustible Flooring

A stone or tiled floor beneath your barbecue isn’t just smart—it’s essential.

It makes cleaning easier, improves safety, and looks great too.

Conclusion: Enjoy Your Outdoor Kitchen Responsibly

Barbecuing under a pergola? Absolutely—but don’t wing it.

With smart choices, a bit of planning, and a good safety setup, your pergola can be the heart of your garden grilling zone. Aluminium pergolas, in particular, offer the best of both worlds—shade and safety—making them a top pick for BBQ lovers.

So light up the grill, invite the neighbours, and enjoy your outdoor cooking the right way—without the fire brigade on speed dial.
