How Sligo’s Wild Weather Is Turning Roof Spaces Into Mould Havens
The views from Strandhill and Rosses Point are stunning, but coastal living in Sligo comes with a hidden cost that many homeowners overlook: attic mould.
As Sligo faces increased rainfall, storm-force winds, and salt-laden air, we’re seeing more homes suffering from mould infestations in roof spaces – especially those with poor ventilation, older insulation, or unsealed attic hatches.
Whether you live in a cottage near the sea or a modern home facing the Atlantic, this guide will show you how Sligo’s wild weather is turning attic spaces into mould havens – and how to stop it before it spreads to your living space.
🌬️ Why Coastal Weather Wreaks Havoc on Attics
Homes in Strandhill and Rosses Point are exposed to frequent storms and airborne moisture. Over time, this salty, humid air seeps into roof voids, where temperatures fluctuate and ventilation is often inadequate.
These conditions lead to:
-
Condensation on rafters and roofing felt
-
Black mould forming on timber and insulation
-
Structural wood decay
-
Airborne spores entering bedrooms below
💡 Tip: Even small roof gaps or missing soffit vents can disrupt airflow and cause moisture to build up unseen.
🔍 Signs You Might Have Mould in the Attic
Not sure what to look for? Here are some common red flags we see during professional mould surveys in Sligo:
-
Black or green patches on timber or insulation

🧪 Why Attic Mould Is Dangerous
Mould spores in the attic don’t stay in the attic. Through ventilation paths, cracks in ceilings, and attic hatches, spores can drift into bedrooms and living areas.
Health impacts include:
-
Breathing problems (especially for asthmatics)
-
Fatigue and brain fog
-
Persistent coughing
-
Immune suppression in the elderly or children
💡 Our mould DNA testing service can confirm if toxic mould is present, even if you can’t see it.
