Open Cell Spray Foam Removal in Walsall
Soft open cell foam stripped back from the rafters and roof underside, with timbers cleaned and checked properly for damp and rot.
Open cell spray foam is the softer of the two common types used in UK roofs, and while that makes it somewhat more straightforward to remove than closed cell, it still needs doing properly — stripping it back fully rather than leaving patches, and cleaning and checking the timbers underneath once it's gone.
What makes open cell foam different
Open cell foam has a lighter, more sponge-like structure than closed cell foam, and it doesn't bond quite as aggressively to timber or roofing felt. That generally means removal is a somewhat quicker, less invasive process than closed cell — see our closed cell spray foam removal page for how that compares — though "easier" doesn't mean it can be rushed or done half-heartedly.
How we remove it
We work through the rafters and roof underside systematically, stripping the foam back fully rather than leaving residue that could still obscure a surveyor's view of the timber. Because open cell foam is more porous, it can also hold onto moisture if the roof has had any damp issues, so we're careful to check for that as the foam comes away.
Checking the timbers properly
Once each section is cleared, we clean the exposed timber and check it for damp and rot — a step that matters regardless of why you're having the foam removed, since it's often the first real look anyone's had at the roof structure in years.
Waste and certification
All removed foam is cleared from site, and once the job's complete we issue written certification confirming the foam type, the removal, and our findings on the timber condition — suitable for your own records, a surveyor or a lender.

Trusted by homeowners across Walsall — here's what they have to say.

Frequently Asked Questions
Open cell foam has a lighter, spongier structure and doesn't bond as aggressively to timber as closed cell foam, which generally makes removal a somewhat quicker and less invasive process.
Generally yes, though it still needs to be stripped back fully and the timbers underneath properly cleaned and checked — it's not a job to rush even if it comes away more readily.
It can, since it's more porous than closed cell foam and can hold onto moisture if the roof has had any issues. We check for this specifically as the foam comes away.
We identify the type during a free survey. If you're not sure and want to know before committing to removal, our spray foam survey service covers exactly that.
