There are many reasons why homeowners end up searching for spray foam removal. Maybe your mortgage application was denied, you’re selling your home, remortgaging or applying for equity release. Perhaps a surveyor has highlighted the spray foam or maybe you are simply worried the insulation could be hiding problems with your roof.
The good news is open cell foam is softer and less tightly bonded than closed cell foam so it is generally easier to remove. But that does not make it a job for a DIYer. Foam can still be stuck around rafters and other roof timbers and removing it without the right tools can damage the wood or spread dust through the loft. That’s exactly where we come in!
For 10+ years we have helped homeowners with open cell spray foam removal in the UK. Our team has the equipment and experience to remove it carefully and leave the roof ready for inspection. Our contractors understand UK homes and what surveyors and lenders look for after insulation removal. We also take care of all the paperwork and certificates homeowners need when dealing with RICS surveyors, lenders, mortgages or equity release. Lastly our work is fully insured and backed by a 15-year guarantee so you can have complete confidence that your home is properly looked after.

Why Homeowners Should Remove Open Cell Spray Foam
Open cell spray foam is softer and more sponge-like so it does not seal the roof as tightly as closed cell foam. Poor application can also leave gaps where some air can move through the insulation and make it less effective at keeping heat inside.
The result? The roof can lose heat so your heating system has to work harder and your energy bills can increase. Moisture can also build up around the timbers especially where the foam has been poorly fitted or the roof has existing damp problems. Over time this can lead to mould, damp and timber rot that stays hidden beneath the foam until the roof is inspected.
Surveyors or lenders often flag open cell spray foam because they cannot see the roof condition behind it. The current market states the same:
- A research done by Homeowners Alliance and the BBC found that only 25% of mortgage providers and no equity release lenders will lend on houses with upgraded spray foam insulation.
- In another joint research by the Property Care Association and Homeowners Alliance, more than 500 properties were inspected. 35% had at least one defect caused by spray foam.
- RICS also highlights the risk of moisture becoming trapped by spray foam which can cause condensation and damage to the roof timbers. As this damage may be hidden beneath the foam the roof should be checked using the PCA Sprayed Foam Insulation Inspection Protocol.
If your surveyor has flagged your property due to spray foam we can help. We are experienced at professional open cell spray foam removal and provide all documents you need to support a mortgage, sale or property inspection. This includes removal reports, photographs and other evidence showing the foam has been removed and the roof has been inspected.
What You Receive With Our Spray Foam Removal Service
Safe Removal of Isocyanates
Spray foam removal releases toxic isocyanates which are highly reactive chemical compounds to breathe in or swallow. We follow strict HSE safety rules to limit exposure to isocyanates by using industrial extraction fans and negative air pressure units to remove chemical dust from the loft and attic.
Lenders who Accept Our Reports
Our reports provide supporting documentation for mortgage applications and are accepted by lenders such as Nationwide Building Society, NatWest, The Co-operative Bank and Coventry Building Society, subject to each lender’s own criteria and valuation.
RICS-Compliant Removal Report
At the end of every open cell removal job you will receive a detailed report evidencing that the foam is safely removed and timber is properly cleaned. This is the document your RICS surveyor or lender will ask to see.
Photographic Evidence
Every job includes clear before-and-after photos of every area that is improved after foam removal. You can show it to your lenders or surveyors as photographic evidence that the foam is properly removed. See examples in our gallery.
Licensed Waste Disposal
As an Environment Agency (EA)-registered waste carrier we safely transport all removed foam to a licensed commercial waste facility using secure, eco-friendly waste bags. We also provide a Waste Transfer Note (WTN) that tracks the waste from your home until it reaches the approved disposal facility.
Insurance-Backed Guarantee
A 15-year guarantee underwritten by Confederation of Roofing Contractors 2000 Ltd t/a CORC Insurance. This gives you peace of mind that the work has been completed to a high standard.
Post-Removal Certification
After open cell foam removal we provide improved u-value figures, timber moisture readings and an EBR-01 certificate. These documents are proof that the work has improved the property and the roof is now in good condition.
0% Finance Available
We offer 0% finance options to make open cell foam removal easier to afford. Instead of paying the full cost upfront we help homeowners spread the cost of spray foam removal into manageable monthly payments with no interest.

Conservatories are not all built in the same way. The roof material, frame design, shape and connection to the main property can all affect how spray foam has been installed and how it needs to be removed. This is one reason why we visit the site instead of straightaway working on the conservatory roof spray foam insulation removal process.
During the survey, our team inspects for the following factors:
- Moisture readings from accessible roof timbers and other suitable areas to check for signs of trapped moisture, damp or condensation.
- Test openings — by carefully removing small areas of spray foam to check the roof, frame or other materials underneath.
- Conservatory roof inspection covering accessible rafters, beams, timberwork, roof panels, glazing, roofing membranes, tiles and other parts of the roof structure.
- Roof condition to identify any visible leaks, damaged roof panels, broken or damaged tiles, problems around roof joints or other areas that need attention.
We take these details into account before starting work so the removal is suited to your conservatory rather than using the same approach for every property. This also helps us determine whether only partial or targeted removal is needed or if the spray foam needs to be removed from the entire roof area. For example, when spray foam has only been applied to certain sections of the roof or around specific roof components. Or if your surveyor has flagged specific sections of the roof for removal.
Common Open Cell Foam Problems – And Our Solutions.
Many homeowners who come to us for open cell spray foam roof insulation removal have the same concerns: hidden roof damage, rising heating bills, mortgage problems and reduced resale value. The longer these issues go unnoticed, the more difficult and expensive they can become to deal with.
For some homeowners the problem also came as an unwelcome surprise. Many had spray foam installed through schemes such as ECO4 or the Great British Insulation Scheme without being told that it could later cause problems when applying for a mortgage or selling their home. Then in March, 2025 when the government confirmed there was no financial assistance for foam removal, homeowners were left with no choice but to pay for the removal themselves.
At Smart Spray Foam Removal we understand these concerns and have a practical solution for every problem. With the right removal approach we will help you avoid costly repairs and protect your property’s value for coming years.
| What Could Be Wrong With My Spray Foam? | Here’s How We Put it Right: |
|---|---|
| Can I get a mortgage approval if I remove spray foam in my loft? | We provide a written record of the removal that you can share with your mortgage lender, surveyor or estate agent as proof that the spray foam has been removed. |
| Is spray foam hiding damp, leaks, condensation, mould or timber decay in my roof? | We carefully remove the foam and look for signs of damp or rot. If we find timber damage we show you where it is, explain what has caused it and recommend the next step to stop the problem from spreading. |
| Can I afford spray foam removal after ECO4? I wasn’t aware I might later need to pay for its removal. | We can help. Our 0% finance options can make essential spray foam removal easier to afford so homeowners get the work done without paying the full cost upfront. |
| Why is my home still cold with open cell spray foam? Heating bills rise as I try to keep my home warm. | Poor open cell spray foam installation can lead to gaps, thin patches and cold spots. We scrape out the poorly fitted foam and clear away every bit of it. You get a clean and accessible space for a more suitable insulation system. |
| I cannot install a skylight or add wiring or repair damaged parts of the roof because the foam is covering those areas. | We use special equipment to clear foam from even the tiniest spaces so it’s easy to inspect, maintain and repair or install new features in the future. |
| Can old spray foam affect the air I breathe? | We remove the foam in a controlled way, keep the work area contained and make sure no loose foam is left behind to affect the air in your home. |
| Has spray foam affected my roof warranty and could be leading to costly repair bills? | We clear the foam away so your roof can be properly assessed and provide the documentation needed for future repairs, sales or mortgage applications. |
| Can spray foam cause problems in an older property? | Yes, it can put extra strain on older properties. We remove the foam so your roof can be checked properly and any signs of strain or damage are addressed on time. |
| How is old spray foam disposed of? | We hold a valid waste disposal licence with the Environment Agency (EA) and dispose of all removed foam responsibly. Our team also tidies the area before leaving your property. |
Get Your FREE Roof Health Report!
At Smart Spray Foam Removal every project begins with a free site survey. Our open cell spray foam removal specialists thoroughly inspect the insulated area and mention all the details in a free Roof Health Report that is shared with the client. The report shows the roof’s condition, any problems we find before the work begins as well as which tools or removal methods are needed for each area.
Our free Roof Health Report covers:
- Moisture readings taken from the roof timbers for any signs of damp, condensation or mould.
- Test openings — the team removes small sections of foam to check the condition of the roof underneath.
- A full roof inspection including rafters, beams, roofing felt and tiles or slates.
- Hidden damage checks to identify rot, damp or other problems beneath the foam.
If the report shows the roof is in good condition we can safely proceed with the foam removal. But if there is any damage we will identify those areas and explain what needs to be fixed before we start.
Precision Techniques for Open Cell Foam Removal
Have you seen those loft spaces where spray foam has been ripped out in a hurry, leaving damaged roof timbers behind? It happens when the job is rushed, the wrong tools are used or the foam is pulled away without proper care. We don’t work like that.
Our open cell spray foam removal specialists use precise techniques to safely remove the foam. The exact method depends on how thick the foam is, how strongly it is bonded and what it is attached to. The contractors check this during the survey and choose the safest method for each part of the roof.
Hand Removal for Softer Foam
Our experienced technicians physically pull, peel or loosen the foam by hand. They go one section at a time instead of rushing the job. Because open cell foam is softer than closed foam some sections are easier to remove by hand where they have already loosened from the roof timbers.
Hand Tools for Bonded Foam
For tight spaces, corners, and small gaps like around roof timbers, joints or edges where the foam may have expanded we use hand tools to carefully loosen the foam. Specialist scrapers, chisels, utility knives and saws help in removing every bit of foam from the roof.
Our open cell spray foam removal contractors are especially trained to use a controlled approach. As the foam is soft and can come away in large chunks without warning, we remove it carefully to avoid damaging the timber or roofing felt underneath.
Wire Brushing for Remaining Foam
After the main foam has been removed thin layers or small bits are often stuck to the timber. Our team uses a wire brush to gently scrub away these remaining pieces to expose the clean timber underneath. This is especially useful for removing small amounts of foam from uneven surfaces, corners and timber grain.
