Common Causes of Roof Leaks and How to Fix Them Quickly

Roof leaks can cause major headaches for homeowners, especially when left untreated. In Ireland, where rain is a regular occurrence, even a small leak can quickly turn into a serious issue. Understanding what causes roof leaks and how to resolve them can help you act fast and prevent extensive damage.
Top Causes of Roof Leaks in Ireland.
Broken or slipped tiles.
One of the most common causes. Strong winds or old age can shift or crack tiles, allowing rainwater to penetrate the underlay.
Cracked flashing.
Flashing seals joints around chimneys, vents, and skylights. Over time, it can corrode or lift, breaking the waterproof seal.
Clogged gutters.
If gutters are blocked, water can back up under the roof edge and seep into your home, especially during heavy downpours.
Ageing roof materials.
Even well-installed roofs degrade over time. Felt, tiles, and ridge caps can all deteriorate, especially after two or three decades of exposure.
Poor workmanship.
Leaks often occur at joints or junctions where poor installation failed to create a proper seal.
How to Spot a Leak Early
Watch out for:
- Water stains on ceilings or walls
- Damp smells in the attic
- Dripping sounds during rain
- Peeling paint or discolouration
Temporary Fixes vs Permanent Repairs.
While placing a bucket under the drip or patching the area with a waterproof sheet can provide temporary relief, the real solution lies in proper repairs.
At Patrick Hannifin Roofing, we identify the source of the leak and repair it properly—whether it’s tile replacement, flashing work, or underlay replacement.
Can I fix a roof leak myself?
Small leaks might seem easy, but accessing the roof can be dangerous. Always call a professional to safely diagnose and fix the issue.
How long does it take to repair a roof leak?
Minor leaks can often be fixed in a day, but more serious damage may require a full inspection and several days of work.
Is roof leak repair covered by insurance?
If the leak is due to storm damage or accidental impact, it might be. Wear and tear, however, is usually not covered.
