Overview
Why spray foam has to come out
Spray polyurethane foam was sold across London and the South East as a loft insulation upgrade. Applied to the underside of the roof, it bonds to the rafters, the battens and the felt, seals the ventilation path, and makes the timber it covers impossible to inspect. That last point is the one that ends mortgages: a surveyor who cannot see the structure cannot certify it, and most lenders will not lend against a roof they cannot assess.
Removal means getting the foam off the timbers and the underside of the covering, taking out the material that has bonded to the felt, and reinstating the roof deck so the structure is visible, ventilated and sound again. It is dirty, slow, physical work, and the difference between a proper job and a cheap one is whether the timbers are actually clean at the end or simply less foamy.
We remove spray foam and reinstate the roof so it can be surveyed and mortgaged again. No certificate is issued for the removal itself — none exists — but every removal we have carried out has been signed off by building control and surveyors without issue.
When it is needed
As soon as a lender, surveyor or buyer raises it, and before any re-roofing work — foam has to come out before a covering can be replaced properly.
Why professional help matters
Foam removal that damages rafters, battens or the covering creates a worse problem than the foam. It also has to be paired with a competent assessment of the timber underneath, because that is exactly what the surveyor will be looking at.
What you get afterwards
A roof space that can be inspected, correct ventilation restored, the deck reinstated, and a documented record of the work for your lender, buyer or surveyor.
What Goes Wrong
What leaving spray foam in place actually costs
Foam does not cause a leak you can see. It causes a set of problems that only surface when you try to borrow against, sell or re-roof the property.
Mortgage and equity release refusals
Lenders decline against roofs they cannot survey. That can stop a sale, a remortgage or a later-life equity release outright, regardless of the condition of the rest of the house.
Rot hidden under the foam
Sealing the underside of a roof removes the airflow that kept the timber dry. Condensation forms against the rafters and battens where nobody can see it, and by the time it is found the repair is structural.
Sale price knocked down
Buyers who will proceed at all will price the removal in, usually at more than it would cost you to have it done properly first.
Re-roofing becomes impossible to price
No roofer can quote confidently on a roof whose timbers and battens are encased. The foam has to come out either way, so it may as well come out on your terms.
Common mistakes we are called to fix
- Assuming a 'certificate' exists for spray foam removal — it does not, so judge the contractor by their track record with surveyors instead.
- Having the foam scraped back roughly and leaving residue bonded to the felt and battens.
- Removing the foam without restoring eaves and ridge ventilation, so the condensation problem stays.
- Letting the same company that installed the foam decide whether it needs removing.
- Waiting until a buyer's surveyor raises it, with a chain waiting on the answer.
How It Works
From first call to
a guaranteed finish
- 01
Inspection
We inspect the loft, identify the type and depth of foam, check where it has bonded, and assess as much of the timber and covering condition as is visible before removal.
- 02
Diagnosis and written quote
You get a written scope covering removal, deck reinstatement, ventilation and disposal, with any likely timber issues flagged up front. Free for homeowners; £150 for pre-purchase surveys, deducted from your quote if you proceed.
- 03
Removal
The foam is removed from rafters, battens and the underside of the covering, with the loft protected and the waste bagged and taken away. Where foam has bonded to perished felt, that material comes out with it.
- 04
Deck reinstatement and ventilation
The roof deck is reinstated so the roof is weathertight and inspectable, and the eaves and ridge ventilation path is restored so the roof space breathes again.
- 05
Verification and handover
The finished roof space is walked and photographed so you have a record for your lender, buyer or surveyor. Our removals have consistently been signed off by building control and surveyors without issue.
What You Get
The outcome you are
actually paying for
Mortgageable again
A roof space a surveyor can actually inspect is the whole point, and it is what unlocks the sale, remortgage or equity release.
A track record that stands up
Every removal we have carried out has passed building control and surveyor scrutiny — the closest thing to a certificate that exists for this work.
Hidden defects found
Removal is the only way to see the timber. Anything wrong is photographed and priced rather than discovered by the buyer's surveyor.
Condensation stopped at source
Restoring the ventilation path removes the mechanism that was quietly wetting the timbers under the foam.
One firm, foam to finished roof
If the roof needs re-covering afterwards, the same team carries it through with a 25-year pitched roof guarantee rather than handing you on.
Clean, contained, insured
Loft protected, waste removed, £1,000,000 public liability cover behind the work.
In Detail
Foam types, removal methods and what happens next
Not all spray foam behaves the same way, and what is underneath it decides how much work follows the removal.
Open cell and closed cell foam
Open cell foam is softer, lower density and more permeable. It generally releases from timber more readily, but it holds moisture and is often found saturated on roofs that have been sealed for years.
Closed cell foam is rigid, dense and strongly adhesive. It bonds hard to battens, rafters and felt, and removal is a slower mechanical process. It is also the type most likely to have taken the felt with it by the time it comes off.
Removal method
Removal is mechanical and manual: cutting the bulk away from between and around the rafters, then working the residue off the timber faces so the structure is genuinely clean and inspectable rather than cosmetically improved.
The loft is protected and the working area contained, with waste bagged and removed from site. Access, ceiling protection and dust control matter as much as the roof work itself, because everything below the loft hatch stays occupied.
Deck reinstatement
Where the original felt has been destroyed by the foam — the usual outcome with closed cell — the roof deck is reinstated so the roof is weathertight and the structure can be seen. That reinstatement is what turns a stripped loft back into a roof a surveyor will sign off.
Where the covering above is also at the end of its life, reinstatement is the natural point to discuss a full re-roof, since the scaffolding, access and stripping overlap and the finished roof carries a 25-year guarantee.
Ventilation and insulation afterwards
A roof that has been sealed with foam has usually lost its eaves ventilation entirely. Restoring airflow at the eaves and, where appropriate, at the ridge is what stops condensation returning once the foam is gone.
Conventional loft insulation at the ceiling level then does the job the foam was sold to do, without hiding the structure, blocking ventilation or costing you a mortgage offer.
Surveys, lenders and paperwork
There is no industry certificate for spray foam removal, and any contractor promising one is describing something that does not exist. What lenders and surveyors respond to is an inspectable roof space, evidence of the work carried out, and a contractor whose removals have consistently been accepted.
We photograph the roof space before and after so you have documentation to hand to your surveyor, lender or buyer's solicitor.
Residential and commercial
The overwhelming majority of foam removal is domestic — houses and bungalows across Morden, Merton, Sutton, Croydon, Kingston and the wider Surrey and London area, usually triggered by a mortgage or sale.
Commercial and mixed-use buildings occasionally carry foam in roof voids for the same reasons, and the same removal and reinstatement approach applies, phased around occupancy.

Questions
Spray Foam Removals
questions we get asked
If your question is not here, call 07808 839833 and speak to a roofer rather than a call centre.
How much does spray foam removal cost?
It depends on the roof area, the type and depth of the foam, how hard it is bonded, and how much deck reinstatement follows. The survey is free for existing homeowners and the work is quoted in writing before it starts.
Will removal get my mortgage approved?
Removal restores a roof space the surveyor can inspect, which is the obstacle in almost every declined case. Lending decisions remain the lender's, but every removal we have carried out has been signed off by building control and surveyors without issue.
Do you issue a certificate for the removal?
No certificate exists for spray foam removal itself. What we provide is a properly reinstated, inspectable roof and photographic documentation — and a track record of removals accepted by building control and surveyors.
How long does removal take?
Most domestic removals are a matter of days depending on area and foam type. Closed cell foam on a large roof takes longer, and deck reinstatement adds to the programme. You get a timeframe with the quote.
Will removal damage my roof?
The felt underneath is often already destroyed by the foam — that is the foam's doing, not the removal's. That is exactly why reinstatement of the deck is part of the job rather than an extra.
Will I need a new roof afterwards?
Not always. If the covering has life left, deck reinstatement is enough. If the covering is at the end of its life, we will show you why and price a re-roof, which carries a 25-year guarantee.
Can I just leave the foam and insulate over it?
It will not solve the lending or survey problem, and it does not restore the ventilation that keeps your timbers dry. If a lender or surveyor has raised it, removal is the route.
What insulation should I use instead?
Conventional insulation at ceiling level, with the eaves ventilation path kept clear. It performs, it is inspectable, and it does not compromise the sale of the house.
Are you insured for this work?
Yes. We hold £1,000,000 public liability cover and details are provided with every quote.
Do you cover my area?
We work from Morden across Greater London, Surrey, Kent, West and East Sussex, Hampshire, Reading and the Isle of Wight.
