Black mould on your loft insulation? Here’s what to do
Estimated reading time: 2 minutes
Why is my loft insulation mouldy?
Mould thrives in moist, poorly ventilated conditions. In loft spaces, several factors can contribute to dampness:
- Condensation: Warm, humid air from living areas rises and meets cold surfaces in the loft, leading to condensation.
- Excess moisture due to poor ventilation: Without proper airflow, any moisture trapped in the loft can accumulate over time, allowing mould to grow.
- Roof leaks: Damaged or inadequate roofing materials can allow water to seep through, creating a damp environment which creates perfect conditions for mould growth. You will need to get this fixed by a professional roofing company immediately.
Is it mould on my loft insulation?
Identifying early signs of mouldy loft insulation is key to preventing structural damage to your home. Some signs you should look out for are:
- Discoloration: Mould often appears as black patches on insulation.
- Musty odour: A persistent, damp and earthy smell in your loft is a strong indicator of mould presence.
Regular inspections of your loft space can help catch these signs early.
Although you may only enter your loft infrequently, mouldy loft insulation can be a health hazard. Exposure to mould spores can pose multiple health risks, especially when it comes to respiratory and allergic complications.
