Common Gutter Problems in Coastal Areas – and How to Fix Them
Why seamless aluminium still wins – especially in our climate
Living along KwaZulu-Natal’s South Coast or its nearby inland towns like Kokstad comes with all the beauty – and all the rain. From salty sea air in places like Margate, Port Edward, and Ramsgate, to chilly winters in high-altitude inland areas, your gutter system works harder than you think. But here’s the truth: not all gutters are made to handle our environment.
Whether you’ve got traditional steel gutters, flimsy PVC pipes, or are considering an upgrade, let’s break down the most common gutter issues homeowners face here – and what to do about them.
1.
Rust, Corrosion & Cracks
Coastal areas like Port Shepstone, Margate, and Ramsgate are exposed to high salt content in the air – and that means steel gutters corrode fast. Meanwhile, cheaper PVC gutters may not rust, but they crack, warp or become brittle with UV exposure over time.
Fix it:
Our seamless aluminium gutters are non-corrosive, UV-resistant, and custom-formed on-site — giving you long-term protection with minimal maintenance. They also hold their shape better than PVC in fluctuating temperatures inland.
2.
Blocked Gutters from Coastal Debris
Salt air isn’t the only problem – tropical foliage, wind-blown leaves, and palm fronds clog gutters often along the coast. PVC systems are usually sectional, meaning more joins – and more places for debris to get stuck. And once blocked, everything overflows.
Fix it:
Start with regular maintenance – our gutter care guide shows you what to look for. You can also install custom-fit mesh screens or leaf guards – especially helpful if you’re near lots of trees.
3.
UV Damage & Warping (Particularly in Kokstad or Inland)
Inland areas like Kokstad experience hot, sunny days and chilly nights. This constant expansion and contraction leads to cracks and warping, particularly with PVC gutters, which become brittle over time. Steel handles it better – but still corrodes.
Fix it:
Our aluminium systems are built to handle temperature shifts, UV exposure, and frost. It’s part of what makes them ideal for high-altitude inland homes – they remain structurally sound, no matter the weather.
4.
Poor Alignment or Slope
We see this all the time with PVC systems: the brackets loosen, the plastic bends, and slope is lost, meaning water pools, stagnates, or overflows in the wrong spots. Even steel gutters can warp over time without proper installation.
Fix it:
Our team uses on-site measurement and installation to get your slope 100% right – no water pooling, no sagging. Read more about what to expect during the installation process.
5.
Discolouration & Aesthetics
Sun and salt make PVC gutters fade fast. Steel rusts, peels, and stains. Your home’s curb appeal suffers. Coastal homeowners especially notice how quickly PVC systems start to look dirty or warped.
Fix it:
Our aluminium gutters come in a wide range of durable colour finishes that stay vibrant in the sun – with minimal fading. They’re also seamless, meaning no joins, leaks, or unsightly lines.
6.
Overflow During Rainy Season
PVC systems often have smaller internal volumes and can’t handle heavy summer rains. Overflow doesn’t just mess up your garden – it leads to foundation damage, mould, and wall erosion.
Fix it:
Check out our maintenance checklist, especially ahead of summer. And if you’re upgrading, our team sizes your system specifically for your roof’s square meterage and local rainfall patterns.
BONUS:
Use That Water – Don’t Waste It
Did you know you can redirect your runoff into a water tank? Great for your garden, emergency storage, or household use. In drier inland zones or water-restricted areas, this makes a real difference.
Fix it:

Why Aluminium from Hibiscus Gutters Is a No-Brainer
Aluminium wins every time:
- Stronger than PVC, lighter than steel
- Seamless = fewer leaks and clogs
- Rust-proof (perfect for salt air)
- Custom colour finishes that last
- Built for South African climates – coastal and inland
