Stepping out to your driveway in the pouring rain your car bone-dry beneath a sleek, modern shelter. No rust on the frame, no peeling paint, and no worries. The everyday magic of an aluminium carport. But here's the question:
How long do aluminium carports actually last?
Let’s be honest. If you’re investing thousands of pounds in outdoor shelter, you want to know it’ll go the distance. The good news? Aluminium carports are built to last and they really mean it.
What Makes Aluminium So Long-Lasting?
Aluminium doesn’t shout for attention, but it’s quietly powerful. It’s used in aircraft, skyscrapers, and sports cars and for good reason.
Here’s why aluminium stands the test of time:
-
It doesn’t rust like steel
-
It won’t rot like timber
-
It forms a natural oxide layer that protects itself
-
It holds up against UV rays, rain, wind and snow
-
It’s incredibly lightweight yet stronger than you'd think
A well-installed aluminium carport can last 30–40 years (and often longer) with minimal fuss.
Lifespan in Plain Terms
Here’s what you can realistically expect:
Quality Level |
Lifespan Range |
Entry-level (DIY kits) |
15–25 years |
Mid-range models |
25–35 years |
Premium aluminium builds |
35–45+ years |
That’s 3-4 decades of reliable, weatherproof shelter with very little upkeep.
What Impacts the Lifespan of an Aluminium Carport?
Not all carports are created equal. Here's what affects how long yours will last:
1. Build Quality
A flimsy frame won’t cut it. Choose a supplier that offers thicker gauge aluminium and reinforced roof bars.
2. Installation
Professional installation = peace of mind. A poor fit can lead to leaks, frame stress, or even collapse in bad weather.
3. Maintenance
Good news maintenance is minimal. Just hose it down twice a year and check for debris in the gutters.
4. Exposure
If you’re in a coastal area or high-wind zone, ask about marine-grade coatings or reinforced anchoring.
Why It Beats Timber & Steel Every Time?
Still considering wood or steel? Here’s why aluminium wins:
-
No rot, warping or mould
-
No rust or corrosion
-
No painting or sealing required
-
Lighter, quicker, easier to install
-
Fully recyclable and eco-friendly
What Else Do I Need to Know?
You might also be wondering about planning permission. In most cases, you don’t need it if your carport:
-
Is under 2.5m in height
-
Is placed behind your front wall
-
Doesn’t take up more than half your garden area
FAQs
