Open-cell foam
Spongy when pressed and lets some water vapour through, which is why it's often sold as "breathable". It's usually more straightforward to remove from inside the loft.
Spray foam removal
Spray foam causing problems with your roof?
Spray foam can look like a simple way to insulate a loft. When it's been wrongly specified or installed, it can cause serious problems. We'll explain what we find, how proper removal works and what you can put back in its place.
Why it matters
The problems spray foam can cause
What may start as a small problem can become a much more expensive one if it isn't identified and dealt with properly.
Damp & mould
- Trapped moisture
- Restricted ventilation
- Condensation and mould
Moisture is one of the biggest concerns with spray foam. If it becomes trapped or ventilation is restricted, the roof space can become damp. Over time, that can lead to mould, condensation and decay in the roof timbers.
It can damage your roof
- Timbers hidden from view
- Moisture damage under the foam
- Costly repairs if left
Spray foam makes it difficult to inspect the roof and its timbers properly. Problems can be hidden beneath it, including moisture damage and timber decay. Depending on the roof's condition, putting things right can be a significant expense. Don't wait until it becomes an expensive repair.
Selling or remortgaging
- Buyer and surveyor questions
- Lender requirements
- Delays and extra surveys
Spray foam can complicate selling your home or arranging a mortgage or remortgage. Buyers, surveyors and lenders may want to know more about the installation and the condition of the roof, which can lead to delays, additional surveys and potentially expensive remedial work.
Know what you have
Open-cell or closed-cell?
There are two main types of spray foam. Which one you have affects how it's removed and what else might need checking, so it's one of the first things we confirm.
Closed-cell foam
Dense, rigid and firmly bonded to whatever it was sprayed on. It doesn't let moisture through, and removing it is generally a more involved job that needs careful planning.
Removal
There's a right way to remove it
Removing spray foam isn't just a case of ripping it off the roof. It needs care to avoid further damage, and so the roof structure can be properly assessed. Not every company does it the same way.

We identify the type of foam and look at the accessible areas of your roof.
- Step 02
Explain
We explain what we've found, what we recommend for your roof and why. Ask us anything.
- Step 03
Remove
Careful removal to limit further damage, with your home kept clean and tidy.
- Step 04
Check & insulate
We explain what should be checked once the foam is off, then talk through replacements.

FAQs
Spray foam questions
Honest answers, including the ones other companies avoid.
Can I remove spray foam myself?
We wouldn't recommend it. Foam is often bonded to the roof membrane and timbers, and can hide electrical cables. Done badly, removal can damage the roof and make it harder to assess properly afterwards.
Does all spray foam need removing?
Not necessarily. It depends on the type of foam, how it was installed, the condition of the roof and your plans for the property. We'll explain what we find and why we would or wouldn't recommend removal.
Will you give me documents and photos?
Yes. Before work starts we explain exactly what documentation and photographs can be provided, so you know what you'll have to show a buyer, surveyor or lender.
Will removal guarantee my sale or mortgage?
No one can honestly guarantee that, because every lender and surveyor makes their own decision. Careful removal with a clear record of the work puts you in a much better position. Check current requirements with your lender or broker.
What if you find damage under the foam?
We'll show you what we've found and explain what other work, if any, may be needed. Nothing extra goes ahead without being explained and agreed with you first.
How long does removal take?
It depends on the size of the roof, the type of foam and access. We'll tell you what to expect, including timescales, before anything begins.
