There is no single price for removal, because roofs and foam differ so much.
What changes the price
Roof area, foam type, how firmly it has bonded, access to the roof space and the repairs needed afterwards all play a part. Open-cell and closed-cell foam also take different effort.
Why we survey first
A survey lets us quote from real measurements. Typical houses often run to several thousand pounds, but we give a written figure only after seeing the roof.
