Closed-cell spray foam is the harder, denser variant — rigid, bonded firmly to roof timbers and felt. Removal demands more time, sharper tools, and experience reading timber condition through tightly-bonded foam. We work it back carefully so the timbers come out undamaged and the lender's surveyor can sign off cleanly. Closed-cell removal in West Yorkshire runs £65-80 per m². A typical detached property comes to £4,500-7,500 all-in including disposal and the paperwork pack.
Soft, flexible foam — quick to identify, faster to remove.
