Spray foam insulation may seem like a quick energy-efficiency fix — but when incorrectly installed or applied to older roof structures, it can cause serious long-term damage.
As shown in the images above, spray foam can:
• Trap moisture against timber rafters
• Prevent natural ventilation within the loft space
• Accelerate timber rot and structural decay
• Cause mortgage and survey issues when selling your home
• Lead to expensive structural repairs if left untreated
When spray foam is applied directly to roof timbers without proper assessment, condensation becomes trapped. Over time, this creates the perfect conditions for fungal growth, wet rot, and structural deterioration — often hidden until significant damage has occurred.

✔ Safely remove spray foam insulation
✔ Assess and treat timber damage
✔ Restore proper ventilation
