Why Corners Matter

Why Aluminium Guttering is the smart choice for Northern Ireland Homes

Fri, 13 Mar 2026 14:26:48 GMT

If you are thinking about replacing your guttering, the choice of material matters more than most people realise — especially in a county like Tyrone or Fermanagh where the weather does not hold back.

We have been fitting guttering across Northern Ireland for over 30 years. In that time, we have seen every material in action — uPVC, cast iron, steel, and aluminium. And while each has its place, seamless aluminium guttering has become our recommendation for the vast majority of homes we work on. Here is why.

It is made to measure — no joints, no leaks

The biggest cause of guttering failure is joint failure. Every join in a traditional guttering system is a potential weak point — a place where sealant degrades, water backs up, and leaks develop behind your fascia boards.

Seamless aluminium guttering is formed on-site from a continuous coil of aluminium, shaped exactly to the length of your roofline. There are no mid-run joints. The only connections are at corners and downpipes — where joins are genuinely necessary. It is a fundamentally more watertight system from day one.

It handles Northern Ireland weather

Our climate is not kind to buildings. High rainfall, wind-driven rain, frost cycles, and the occasional storm mean that guttering here works harder than almost anywhere else in the UK. Aluminium expands and contracts with temperature changes without cracking or splitting — a significant advantage over uPVC in hard frost conditions. It does not corrode, it does not rust, and it holds its form over decades rather than years.

It lasts — and that matters for your home's value

A well-installed aluminium guttering system, properly maintained, will outlast the roof it protects. We regularly replace uPVC systems on homes where the original aluminium guttering on an extension is still performing perfectly — sometimes after 25 or 30 years. When you are comparing prices, that lifespan has to be part of the calculation.

The supply situation right now

Aluminium is a globally traded commodity and prices move. Current disruption in international shipping — linked to the conflict in the Middle East — has pushed aluminium prices to multi-year highs. If you have been putting off a guttering project, it is worth getting a quote now and locking it in before further increases filter through to the trade supply chain.

We are transparent about this because it affects the advice we give. Our quotes reflect the materials we buy, and right now it pays to move quickly if a job is already planned.

What causes Gutter Failure in homes?

Thu, 18 Dec 2025 14:26:48 GMT

Homes in Tyrone and Fermanagh face unique challenges from harsh weather. High rainfall and strong winds relentlessly stress guttering systems. Problems often develop subtly, leading to costly damage like damp and timber decay. Understanding these common causes helps homeowners take early action and prevent expensive repairs.

Heavy Rainfall & Wind

Consistent heavy rain and strong winds exert continuous pressure on gutters, brackets, and joints. Wind-driven rain can force water into connections, causing leaks and accelerating wear.

Poor Original Installation

Many issues stem from incorrect initial setup. Gutters installed without proper fall or secure fixings will eventually pool water and fail, even years after installation.

Ageing UPVC Joints where plastic guttering was used

UPVC joints and seals naturally degrade over time due to UV exposure, frost, and temperature fluctuations. This leads to hardening and shrinking, causing leaks at connection points.

Incorrect Fall or Undersized Systems

If gutters are too small or lack proper slope, water overflows during downpours or sits stagnant. This increases sagging risks, joint failure, and water spilling onto walls and fascia boards.

Unreset Gutters After Roof Repairs

Gutter alignment is often disturbed during roof work. If not properly reset, even minor shifts can lead to water running behind fascias, causing hidden timber damage.

Regular checks, especially after storms or roofing work, are crucial. Prevent minor gutter faults from escalating into significant, expensive repairs.

Why Corners Matter: The Hidden Weak Spot in Your Guttering System

Mon, 17 Nov 2025 14:26:48 GMT

When people think about guttering, they usually picture long straight runs along the edge of their roof. But the real problems tend to start somewhere else entirely... at the corners. Corners are the point where two lengths of guttering meet. This is also where most leaks begin, where poor installation shows up first and where water damage to fascia, soffits and roof timbers can quickly become costly. As a guttering specialist working across Tyrone, we see the same issue again and again; If the corners aren't installed properly, the whole system fails.

W hy are corners the most common points of leaks?

There is more movement due to expansion and contraction (if PVC Guttering is used)
Two pieces of guttering are connected together
Any small gap becomes a pathway for water
Poor quality sealant used
Poor-quality hangers put pressure on the weakest points of the system
Corners determine the flow of the entire system!

At Clogher Valley Guttering, we use seamless aluminium guttering systems, which means there is less movement compared to PVC gutter systems, seals are stronger and joints are tighter.
