Spray Foam Stripping and Remediation in Walsall
Beyond just removing the foam, we deal with what it's been hiding — treating damp and rotten timbers and restoring a breathable membrane so the roof actually dries out.
Some roofs come out of foam removal needing nothing more than new insulation. Others reveal a genuine problem — timbers that have been sitting damp for years under a foam seal that trapped moisture rather than letting it escape, sometimes with real rot that needs treating before anything else goes back. This service is specifically for that second situation.
Why foam sometimes causes this rather than just hiding it
Spray foam, particularly closed cell foam, can form a vapour-tight seal against timber. If moisture was already present, or gets in later through a small leak or condensation, that seal can trap it against the wood indefinitely rather than letting it evaporate away as a breathable roof structure normally would. Over years, trapped moisture against timber is exactly the condition rot needs to take hold.
What remediation actually involves
Once foam is stripped away — our loft spray foam removal process — we assess the timbers for the extent of any damp or rot, treat affected areas, and replace or repair timber that's structurally compromised rather than just treated and left. We then restore a breathable membrane where the roof's original one has failed or been compromised, and confirm ventilation at the eaves and ridge is doing its job, since restoring breathability without fixing ventilation just recreates the same trapped-moisture problem in a different form.
Why this differs from a standard removal job
Plenty of roofs come out of foam removal in good condition and just need new insulation, which our removal and reinstatement service covers. This service is for the cases where the survey finds a genuine timber or membrane problem that needs proper treatment, not just insulation.
Getting the roof actually dry
The goal isn't just to patch over what's found — it's a roof that dries out properly and stays sound for the long term, with the breathability and ventilation that should have been there all along.

How It Works
From the first call to the final sign-off — here's what to expect when you work with us.
Free Survey
We assess the extent of any damp or rot in the timbers once foam is stripped.
Timber Treatment
Affected timber is treated, or repaired and replaced if structurally compromised.
Membrane Restored
A breathable membrane is fitted where the original has failed or been compromised.
Ventilation Confirmed
Eaves and ridge ventilation is checked and corrected so the roof can actually dry out.
What Our Customers Say
Trusted by homeowners across Walsall — here's what they have to say.
"Our removal survey found rot on three rafters we had no idea about. Proper treatment, not just a quick patch."
"Explained clearly why the foam had trapped moisture rather than caused it, and what needed doing about the membrane."
"Roof's noticeably drier now the ventilation's actually working as it should."
Frequently Asked Questions
Foam, particularly closed cell foam, can form a vapour-tight seal against timber. If moisture is present or gets in later, that seal traps it against the wood rather than letting it evaporate, which over years creates exactly the conditions rot needs.
No, many roofs come out in good condition and just need new insulation. This service is specifically for cases where a survey finds genuine damp or rot in the timbers or a failed membrane.
Fitting a new membrane where the roof's original has failed or been compromised, so moisture vapour can escape properly rather than becoming trapped again.
Not on its own — ventilation at the eaves and ridge needs to be working properly too, otherwise the trapped-moisture problem can recur in a different form even with a new membrane in place.
Removal and reinstatement covers the standard sequence of removing foam and fitting new insulation. This service is for the more involved cases where genuine timber rot or membrane failure needs treating first.
