Closed-cell spray foam insulation has become one of the biggest barriers to selling or remortgaging a property in the UK. While it was once marketed as a premium insulation product, lenders, surveyors, and structural assessors now consider it high risk, primarily because of how aggressively it bonds to roof timbers and how easily it can hide structural decay.
As a result, most lenders will not approve a mortgage until the closed-cell spray foam has been professionally removed.
At Countrywide Roofing & Insulation, we are one of the UK’s leading specialists in closed-cell spray foam removal. With more than 1,000 successful removals, our in-house teams work closely with estate agents, banking societies, and RICS surveyors to help homeowners regain mortgageability and protect their property from long-term damage.
Closed-cell spray foam is very different from open-cell foam. It is dense, rigid, and extremely difficult to remove without harming the roof structure, which is why trusted expertise is essential.

Why Removing Closed Cell Spray Foam Is Essential
Closed cell spray foam is known for its strength—but that strength is exactly what causes problems. Once applied, it forms a rock-hard, moisture-resistant shell around the roof timbers. This traps any existing moisture inside the wood, preventing the natural drying cycle that roofs depend on.
The Result?
- Hidden moisture and rot
- Compressed or damaged roofing felt
- Warped or stressed rafters
- A roof that cannot “breathe”
- Structural timber deterioration that surveyors cannot see
Think of closed cell spray foam like concrete poured around your roof timber. Once it’s on, it locks everything in place, including moisture.
Because surveyors cannot assess the condition of the rafters beneath closed cell foam, lenders consider it too risky for lending, even if the homeowner believes the roof is sound.
Removing closed cell spray foam is the only way to restore the roof’s breathability and allow a full structural assessment.
How Closed Cell Spray Foam Causes Mortgage Problems
Mortgage lenders now treat closed cell spray foam as one of the most serious insulation risks in UK homes. The reasons include:
1. It Prevents RICS Surveyors From Inspecting the Roof
If they cannot check timber integrity, they cannot provide a reliable mortgage valuation.
2. It Bonds Aggressively to the Structure
Closed cell foam is so hard and dense that removing it often tears felt and damages rafters if not handled by experts.
3. It Masks Severe Problems
Because no moisture can escape, hidden decay can spread without visible warning signs.
4. It Often Requires Partial or Full Roof Replacement
In some cases, where the foam is too dense or thick, removal may only be possible by stripping the entire roof covering.
These issues mean buyers struggle to secure finance, sales fall through, and homeowners find themselves stuck—unable to sell, remortgage, or release equity.

FAQ Section
1. Why are lenders strict about closed cell spray foam?
Because the foam creates a hard, impermeable shell around rafters, surveyors cannot assess structural integrity. Lenders see this as too risky and often decline finance until the foam is removed.
2. Can I remove closed cell spray foam myself?
No. Closed-cell foam is extremely tough. Attempting DIY removal almost always results in:
- broken rafters
- torn felt
- compromised roof ventilation
- higher repair costs
Closed-cell spray foam must be removed by trained professionals with specialist equipment.
3. How long does closed cell spray foam removal take?
Due to the density of the foam, most projects take 7–14 days, depending on:
- roof size
- foam thickness
- access
- whether partial roof replacement is required
4. How much does closed cell spray foam removal cost?
Closed cell removal is more complex than open cell. Typical costs range from:
£10,000–£50,000+ depending on the extent of removal and remedial work.
