Spray foam insulation failing building regulations
Why it happens here
Foam sprayed between rafters often blocks the eaves ventilation the roof needs. That leaves the loft non compliant with Building Regulations Part L, and it shows up the moment a surveyor looks at the roof space during a sale.
Our approach
We remove the foam fully, open up the blocked ventilation, and check the roof can breathe again. You get a written summary of what was removed and what was done, ready to hand to a surveyor or your solicitor.
