In May 2026 our team removed 40m² of closed cell spray foam from a loft in Birmingham, West Midlands, and laid 30m² of new 300mm loft insulation. The job needed doing quickly: we surveyed it on 11 May and started on 15 May. The work took 2 days.
The loft had closed cell spray foam across about 40m² of the roof, and the job needed doing quickly. Many lenders and surveyors are cautious about spray foam because it hides the roof timbers, so they can't check their condition.
Closed cell foam sets hard and grips the timber, so it takes more work to remove than the softer open cell type.
What we did
Removed 40m² of closed cell spray foam from the roof
Laid 30m² of 300mm loft insulation
The result
Two days after starting, the rafters were clear of foam and the loft floor had new 300mm insulation, as the photo above shows. The roof timbers can be seen again by anyone who needs to inspect them.
A check you can do yourself
Not sure which type of foam you have? Press it gently with a gloved hand. Open cell foam is soft and gives a little. Closed cell foam is hard and rigid. Knowing which you have helps when you ask for quotes.
Questions about this job
Is closed cell spray foam harder to remove?
Generally, yes. Closed cell foam sets hard and grips the timber. On this Birmingham job, 40m² of closed cell foam came out over 2 days, along with new insulation going down.
Do you reinsulate after removing spray foam?
We can. On this job we laid 30m² of 300mm loft insulation once the foam was out.
Why are lenders cautious about spray foam?
Many lenders and surveyors are cautious about spray foam because it can hide the roof timbers, so they can't check their condition. Removing it puts the timbers back on show.
