The Spray Foam Crisis
Polyurethane spray foam insulation was heavily marketed in the UK as a miracle energy-saving solution. However, when applied incorrectly to the underside of roof tiles and timbers, it causes severe structural issues.
Warning for Homeowners
Closed-cell spray foam completely seals the roof space, preventing natural ventilation. Because surveyors cannot inspect the timbers beneath the foam, most UK banks and equity release companies will now refuse to offer mortgages on properties with spray foam installed.
Our Professional Removal Service
Removing spray foam is a highly specialised, labour-intensive process. It cannot simply be ripped down without risking severe damage to the roof structure or electrical wiring.
- Careful Extraction: We use specialised tools to meticulously scrape and remove the foam from your rafters, felt, and slates, ensuring we do not damage the underlying structure.
- Timber Inspection: Once removed, we can assess the state of your roof timbers and advise if any damp has begun to set in.
- Restoring Breathability: By removing the foam, we restore the necessary airflow to your roof space, saving your home from future structural failure.
- Re-Insulation: We can then install proper, breathable, and building-regulation-compliant Knauf Earthwool on the loft floor, where insulation actually belongs.

Book Urgent Foam InspectionFrequently Asked Questions
Why is spray foam insulation bad?
Closed-cell spray foam seals roof timbers, preventing them from breathing. This traps moisture and causes rapid rotting. Most UK mortgage lenders will not lend on a property with spray foam installed.
Can spray foam be safely removed?
Yes, but it is a highly specialised process. Our experts painstakingly scrape and extract the foam without damaging the underlying slates, felt, or structural timbers.
Do I need to replace the insulation after removal?
Yes. Once the foam is removed from the roofline, we strongly advise installing proper, breathable Knauf Earthwool on the loft floor to maintain your home's thermal efficiency.
