Artificial Turf for Balconies and Rooftops Explained

Why turf makes sense on a balcony

Turf for a balcony or rooftop calls for different decisions than a backyard does: shorter pile, no fixing anything down, and getting drainage and wind right. Here's how to choose the spec and lay it properly, whatever hard surface you're starting from. Done well, a layer of turf changes the feel of the whole space for a few hundred dollars: soft underfoot, green year-round, and kind to bare feet, kids and dog paws. It also covers stained or dated tiles without a renovation.

The strata question comes up early, so here's the short version. Loose-laid turf isn't a structural change and doesn't penetrate anything, so most bodies corporate have no issue with it. Some do have bylaws covering balcony appearance or anything visible from the street, so check your bylaws before you order, and get any approval in writing. Anything glued or screwed down is far more likely to need permission, which is one more reason the loose-lay method below is the way to go.

Weight is a non-issue. Turf runs roughly 2 to 3 kg per square metre. One medium planter box full of wet soil weighs more than the turf for an entire balcony. If your balcony can hold a chair, it can hold turf.

What spec suits a hard base

Long, plush pile is built for backyards, where a compacted base and sand infill hold it upright. On concrete, tiles or decking, shorter pile performs better. A 20 to 30mm pile sits flatter, resists crushing under furniture legs, clears door sills, and is easier to sweep and hose. Our pile height guide covers the trade-offs in full, but here's how they stack up on a balcony specifically:

	20mm	30mm	40mm
Look	Neat, freshly-mown	Lawn-like	Lush, deep
Under furniture	Best crush resistance	Good, brush occasionally	Flattens, needs regular brushing
Door clearance	Rarely a problem	Check sliding door tracks	Can catch on low sills
Cleaning	Easiest	Easy	Traps leaves and fur
Balcony verdict	Best for high traffic and tight budgets	Best all-rounder	Usually overkill

For a small covered balcony that gets daily use, a 20mm product like Turf Starter 20mm is honest value. If you want it to read as a little lawn rather than green carpet, the extra pile on Turf Classic 30mm is worth having, and you can price your exact size with the calculator on the product page.

On cost, balconies are where turf is cheapest to do well. Across the Australian market, budget turf in the 15 to 25mm range runs about $15 to $30 per square metre supply-only, and mid-range 25 to 35mm product about $30 to $45 (inc. GST). On an 8m² balcony, the difference between budget and mid-range is often less than $150 total, so don't let per-metre pricing scare you off the nicer product.

Installing without fixing anything down

This is the renter-friendly part. On a hard surface you skip the entire base build that a backyard needs: no excavation, no crusher dust, no compacting. The slab is your base.

Prep the surface

Sweep it, wash it, let it dry completely. Check where water runs when you hose the balcony, because that fall needs to keep working after the turf goes down. If water already pools somewhere, turf won't fix it and will hide the problem, so sort ponding first.

Loose-lay with outdoor tape

Cut the turf to fit the space, lay it with the pile leaning toward where you'll view it from, and let it relax for a few hours in the sun so it sits flat. On a sheltered balcony, furniture and a couple of planters around the edges are often enough to hold it. Where edges want to lift, use double-sided exterior carpet tape around the perimeter. Test the tape on a hidden corner of your tiles first and check it peels off clean. No glue, no screws, and the whole lot comes with you when you move.

One caution for timber decking: tape can pull at paint or worn sealant when removed. On decking, favour weight over adhesive, or tape sparingly.

Never block the drainage

Turf backing is punched with drainage holes, so rain passes straight through to the surface below and follows the existing fall to the drain. Your job is to not interrupt that. Don't run tape in continuous strips across the fall line, don't lay turf over a floor waste or scupper, and leave a small gap at the drainage outlet so water exits freely. Blocked balcony drainage is the one genuine way turf causes damage, and it's entirely avoidable.

Cutting around posts and corners

Cut from the back of the turf with a sharp utility knife, and swap blades often because backing dulls them fast. For a post or rail upright, measure its position, cut a slit from the nearest edge to that point, cut the hole slightly undersized, then wrap the turf around. The slit closes up and disappears into the pile. Trim in small passes; you can always take more off, and an undercut edge looks worse than three careful cuts.

Rooftops: wind is the real enemy

Everything above applies to rooftops, with one big addition. A rooftop cops gusts that a recessed balcony never sees, and wind doesn't push turf around so much as get underneath an edge and peel it up. Loose-lay alone is not enough up there.

Secure the perimeter and the wind can't get a grip. Options, roughly in order of commitment: heavy ballast along every edge (planters, pavers, built-in furniture), exterior tape around the full perimeter, or a suitable outdoor adhesive at edges and joins where the surface allows it. On bigger rooftops where you're joining rolls, tape the joins from underneath so the whole area behaves as one heavy sheet, which is much harder to lift than separate panels.

Two rooftop-specific warnings. First, many rooftops are waterproof membranes, and you never screw or glue into a membrane. Ballast and loose-lay protect it; penetrations void it. Second, rooftop use often needs building management sign-off even when a balcony wouldn't, so ask first.

Living with turf in full sun

Be realistic here: artificial turf gets hot in direct summer sun, noticeably hotter than real grass, and an exposed west-facing balcony is the worst case. A quick hose-down cools it in seconds, lighter colours run cooler than dark ones, and shade sails or an umbrella help a lot. Also watch for concentrated reflections off energy-efficient window glass, which can overheat a small patch of any turf.

Ongoing care is minimal. Brush against the pile every few weeks to keep it standing, rinse off dust and bird droppings, and rinse more often if a dog uses it. The full routine is in our maintenance guide, and there's more balcony-specific detail on our turf for balconies page.

Measuring up a balcony

Turf commonly comes in 3.71m wide rolls, and most balconies are narrower than that, which means a single piece with no joins at all. Measure the longest length and the widest width, order that full rectangle, and trim to shape on site. Cutting off excess is normal; going back for a second piece that won't colour-match is the mistake to avoid. Our guide on how to measure your yard for turf walks through odd shapes and door openings.

Frequently asked questions

Will artificial turf damage my balcony tiles?

Loose-laid turf won't damage tiles; it actually protects them from furniture scratches and UV fading. The only risk is adhesive residue from tape, so use a removable exterior-grade tape and test it on a hidden corner first. Lift the turf and rinse underneath once or twice a year so grit and trapped moisture never sit against the surface long-term.

Can I put turf on my balcony if I'm renting?

Yes, and it's one of the few outdoor upgrades renters can genuinely do. Loose-lay the turf with furniture or planters holding the edges, skip glue and screws entirely, and it lifts out in minutes when you move. If your building has bylaws about balcony appearance, a quick written OK from the landlord or strata covers you.

How does water drain through turf on a balcony?

Turf backing has drainage holes punched through it, so rain passes straight to the tiles or concrete underneath and follows the balcony's existing fall to the drain. You only strike trouble if the turf or tape covers a floor waste or scupper, so keep those clear and leave a gap at the outlet. If your balcony already pools water, fix that before laying anything over it.

Will turf blow away on a windy rooftop?

An unsecured piece on an exposed rooftop can lift, because wind gets under a free edge and peels from there. Secure the full perimeter with ballast, exterior tape or adhesive where the surface allows, and tape any joins underneath so the area acts as one sheet. With edges held down, turf is very difficult for wind to move.
