Closed Cell Spray Foam Removal in Walsall

Closed cell spray foam is the tougher of the two common foam types, and it earns that reputation the moment you try to remove it. It bonds hard — genuinely hard — to roof timbers, felt, and often directly to the underside of slates and tiles. Stripping it out without damaging what it's stuck to takes a specifically careful, mechanical approach, not brute force.

Why closed cell foam is harder to remove

Unlike the softer, more porous open cell foam, closed cell foam has a dense, rigid structure that adheres tightly to whatever surface it was sprayed onto. That's exactly why it was popular as an insulation product — it's a strong, effective seal — but it's also why removal takes real skill rather than just pulling or scraping it away, which risks pulling the roof covering apart along with it.

Careful mechanical stripping

We use mechanical stripping methods suited to how hard the foam has bonded in your specific roof, working section by section rather than forcing large areas away at once. This protects the felt, slates or tiles underneath from the kind of damage that turns a foam removal job into a roof repair job as well.

Checking as we go

As each section comes away, we assess the timber and roof covering underneath for damp, rot or any damage the tightly-bonded foam may have caused or been concealing. Closed cell foam's rigid seal can sometimes trap moisture in ways that aren't obvious until the foam's actually gone.

Disposal and certification

All removed foam is disposed of properly, and once the work's complete we certify it — confirming the foam has been fully stripped, the method used, and our findings on the roof's condition. This is the same certification detailed on our certification for lenders page, suitable for surveyors and mortgage applications.
