Closed cell spray foam can become a serious problem when you want to sell, remortgage or have your roof assessed.
Next Generation Insulation provides specialist closed cell spray foam removal across Birmingham, Coventry, Stafford and the wider West Midlands, as well as Derby, Nottingham and Leicester.
We assess how the foam has been applied, inspect the condition of the roof and explain the most suitable way to remove it. Where the foam has bonded to roofing materials or damage is found after removal, our roofing team can also carry out the repairs or roof replacement required.
After the agreed work is complete, we provide removal and completion documentation that can be supplied to your lender, surveyor, solicitor or mortgage broker.
We help homeowners who are:
If you are unsure what type of spray foam you have, we can assess this as part of the survey.
Closed cell spray foam is dense, rigid and can bond firmly to roof timbers, membranes, battens and the underside of tiles or slates.
This is one of the main differences between closed cell and open cell spray foam.
The strength of that bond can make closed cell foam harder to remove without affecting the materials underneath it. In some properties, the foam can be removed carefully from inside the loft. In others, sections of the roof covering may need to be removed to gain proper access.
There is no single removal method that is right for every roof.
Before recommending any work, we look at:
This allows us to explain what can realistically be removed and whether any additional roofing work is likely to be required.
Closed cell spray foam can cause problems during a house sale or remortgage because parts of the roof may be difficult for a surveyor or valuer to inspect.
A surveyor may need to assess the:
Where these areas are covered by spray foam, it may not be possible to assess their condition properly.
A lender may then request further investigation, specialist reports or removal before deciding whether to proceed with a mortgage or remortgage.
This does not mean every property containing closed cell spray foam will automatically be refused a mortgage. Requirements differ between lenders, properties and valuers.
Where removal has been requested, exposing the roof structure again can allow it to be assessed more thoroughly.
The removal method depends on the foam, roof structure and how firmly the material has bonded.
We inspect the loft and establish where the foam has been applied, its condition and how strongly it has adhered to the roof.
We also look for visible signs of condensation, moisture, damaged membranes or timber deterioration.
The aim at this stage is to determine whether removal can be completed internally or whether access from outside the roof may be required.
Closed cell spray foam removal can involve a combination of methods depending on the individual roof.
These may include:
Dry-ice blasting can be useful on some installations, but it is not the right method for every property.
Where foam is heavily bonded to membranes, roofing materials or timbers, a different approach may be needed.
We explain the proposed method before work starts.
The foam is removed carefully from the accessible roof structure in accordance with the agreed scope of work.
Closed cell foam removal can be labour intensive because the material may be firmly attached to the surfaces underneath it.
Rushing this stage can increase the risk of unnecessary damage.
One of the main reasons for removing spray foam is to make previously covered parts of the roof accessible for inspection.
Once the foam has been removed, the condition of exposed timbers, membranes and other roofing components can be assessed more clearly.
Removal can reveal problems that were previously concealed.
These may include:
Where additional work is required, we explain the problem and provide a separate quotation before proceeding.
Once the agreed work is complete, we clean the accessible work area and check the completed removal against the agreed scope.
We then prepare the relevant removal and completion documentation.
Yes, some closed cell spray foam can be removed without replacing the complete roof.
It depends on how the foam has been installed and what it has bonded to.
Internal removal may be possible where the foam can be separated from the roof structure without causing unacceptable damage.
A different approach may be required where the foam has bonded heavily to:
In these cases, parts of the roof may need to be stripped externally to gain access.
Real experiences from homeowners who have worked with our team.
A reroof is not automatically required simply because closed cell spray foam is present.
However, there are situations where removing part or all of the roof covering may be the more practical option.
For example, where closed cell foam has adhered firmly to the underside of the roof, trying to separate it internally may damage the existing membrane or other roof components.
The roof covering may then need to be removed from outside.
Depending on the property, this can involve removing:
This also allows previously concealed roof timbers to be inspected.
If damaged timber or other defects are identified, those areas can be repaired or replaced before the roof is rebuilt with suitable membrane, battens, ventilation and roof coverings.
Because Next Generation Insulation provides both spray foam removal and roofing services, you do not need to arrange a separate roofing contractor if additional work is required.
Closed cell spray foam removal does not always finish when the foam has been taken out.
The condition of the roof underneath matters.
Next Generation Insulation can provide:
If additional work becomes necessary, we explain what has been found and provide a clear quotation for the work required.
This gives you one company responsible for the spray foam removal and any related roofing work.
After the agreed removal work has been completed, Next Generation Insulation provides formal removal and completion documentation.
Where applicable, this may include:
We can also forward relevant documentation directly to your solicitor, mortgage broker or other appointed professional on request.
Our removal and completion documentation has previously been accepted by mortgage companies as evidence that spray foam removal work has been completed.
Individual lenders, valuers and solicitors can still have their own requirements. You should therefore confirm what documentation is required for your particular sale, mortgage or remortgage.
One of the risks with closed cell spray foam is that you may not know what is underneath it until removal starts.
Foam can conceal:
Finding damage during removal does not necessarily mean the whole roof needs replacing.
Some problems can be dealt with through localised repairs.
Where more extensive work is required, we will explain what has been found and discuss the available options with you.
We do not proceed with additional work without discussing it first.
Once the foam has been removed and any necessary roofing work has been completed, you may need to reconsider how the property is insulated.
Removing spray foam does not mean your loft has to remain uninsulated.
Depending on the property, replacement insulation could include insulation installed at loft floor level or another system suitable for the roof construction.
Ventilation also needs to be considered alongside insulation.
Next Generation Insulation provides loft insulation services as well as spray foam removal, so we can discuss the options available after removal where replacement insulation is required.
Professional closed cell spray foam removal typically costs between £40 and £100 per square metre.
For most standard residential properties, the total cost usually falls between £4,000 and £8,000.
Closed cell foam is generally more expensive to remove than open cell foam because it is denser and can bond very firmly to roof timbers, membranes and other roofing materials. Removal often requires more intensive manual or mechanical work, which can make it around 30% to 50% more expensive than removing softer open cell foam.
The exact cost will depend on the individual property and how the foam has been installed.
Factors that can affect the price include:
Roof size
Amount of spray foam
Foam thickness
How strongly the foam has bonded
Roof construction
Loft access
Removal method
Whether external roof access is required
Condition of the roof
Whether repairs are required afterwards
We begin with an assessment so we can establish the likely removal method and provide a clear quotation based on the work required.
Your quotation will explain the agreed scope of work and anticipated charges.
If additional work is identified once access is gained or the foam is removed, we will discuss this with you before any further work is carried out.
Next Generation Insulation provides spray foam removal, roofing and insulation services across the East and West Midlands.
Our team combines experience across spray foam removal, roofing, insulation and property improvement.
This is particularly important with closed cell foam because removing the material can sometimes expose roofing work that also needs attention.

We maintain £5 million public liability insurance for the work covered by our current policy.
We provide a written quotation explaining the agreed work and anticipated charges.
Where something unexpected is identified after removal begins, we discuss the options with you before additional work proceeds.
We provide formal removal and completion documentation following the agreed work, with additional certification and supporting records where applicable.
We explain the proposed removal method, expected work, documentation and any roofing work that may be required.
Our customers regularly comment on the communication, cleanliness and standard of work provided by our team.

Yes. Closed cell spray foam can be removed, although the method required depends on how firmly the foam has bonded to the roof structure and roofing materials.
Some installations can be removed internally. Others may require external roof access or sections of the roof covering to be removed.
Closed cell foam is generally denser and more rigid than open cell foam and can bond strongly to roof timbers, membranes and roofing materials.
This can make removal more labour intensive and means the roof should be assessed before deciding on the most suitable removal method.
The aim is to remove the foam while preserving sound parts of the roof wherever reasonably possible.
However, some closed cell foam is so firmly bonded to membranes or other roofing materials that those materials cannot be retained. We assess this before recommending a removal method.
Not necessarily.
Some properties only require spray foam removal, while others may need localised roof repairs.
A full roof replacement may be recommended where the foam cannot be separated from roofing materials successfully or where significant roof deterioration is identified.
Removal can make previously concealed parts of the roof structure accessible for further inspection.
Whether this satisfies a particular mortgage lender will depend on the lender, valuer, property and any additional documentation or work they require.
Yes. We provide formal removal and completion documentation after the agreed work has been completed.
Where applicable, this may also include CORC certification, photographic records and other supporting documentation.
Yes. Relevant completion documentation can be forwarded to your solicitor, mortgage broker or another appointed professional on request.
Yes. Next Generation Insulation provides roof repairs and full roof replacement as well as spray foam removal.
If removal exposes roofing problems, we can assess the work required and provide a separate quotation.
The timescale depends on the size of the roof, amount of foam, access, removal method and whether roofing work is required.
We explain the anticipated programme after assessing the property.
Closed cell foam is normally harder and denser than open cell foam, but appearance alone is not always enough to determine the installation accurately.
We inspect the foam before recommending a removal method.
If closed cell spray foam is affecting a house sale, mortgage, remortgage or roof inspection, the first step is to establish exactly what has been installed and what will be required to remove it.
Next Generation Insulation provides closed cell spray foam surveys and removal across Birmingham, Coventry, Stafford, Derby, Nottingham, Leicester and the wider East and West Midlands.
We can assess the foam, explain the removal options and provide a clear quotation for the work required.
