What causes Gutter Failure in homes?

SINEAD MCKENNA • 18 December 2025

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.
