Question answered
What evidence do lenders want after spray foam removal?
The short answer
Lenders do not publish one standard checklist, and positions change, so ask yours directly. In practice the strongest file holds dated photographs before, during and after the work, a written description of what was removed and what lay underneath, a report on the condition of the roof timbers, and any completion document the contractor issues. Dated photographs and a written account carry the most weight.
With the foam gone, a sale or remortgage still hangs on paperwork. You need a record that a lender, buyer or surveyor can read and believe.
Lender positions are dated, so ask for yours in writing
An industry report of November 2024, drawing on a broadcast investigation, named lenders that would not lend where spray foam was installed, and others that dealt with each application individually. Treat that as a snapshot, never a rule. Policies move, and what held then may not hold now.
The RICS consumer guide of March 2023 advises asking your own lender, before installation, whether its policy allows these products at all. The same habit pays off after removal. Ask the lender or your broker what they would want to see, and ask for the answer by email, so that you work from their words rather than a guess.
Do this before you pay for any paperwork; the wider picture is on our spray foam insulation removal page. Asking first stops wasted effort. It stops you commissioning documents the lender will never read, and it shows early whether they expect something unusual, such as a particular surveyor's report.
Dated photographs form the spine of the file
Photographs are inexpensive evidence and often the most persuasive, provided they are organised. You want three sets. The first shows the foam before anything is touched: the whole loft, the rafters, the gable ends and the foam against the roof covering. The second records the work as it proceeds, so a reader can watch foam coming away and the surface beneath emerging. The third shows the cleared timbers and underlay afterwards, in the same positions as the first set.
Matching positions matters. A surveyor comparing a before image of one rafter bay with an after image of the same bay sees the change at a glance. Stand in the same spot, face the same direction and keep the date stamp on, or put the date in each file name.
Our written quote arrives with survey photographs of your roof, and we take more when the work is finished. If you have images of your own from earlier, include them. They show the roof as it stood before anyone interfered.
A written account of what was removed and what was found
Photographs show the roof but do not explain it. A short written account should do that. It needs the address, the dates, the area covered, the foam type as far as it could be identified, the method of removal and where the waste went. The type is worth recording because it affects how the foam behaved and how it came off.
The account should also say what lay underneath. Were the timbers dry or damp? Was there staining, mould or softened wood? Were any battens, rafters or the underlay harmed during removal? Record residue plainly. A note that a thin film remained on one rafter edge is more credible than a claim of perfection, and a reader who meets the first kind of note will trust the rest more.
If removal did cause harm, the file should say so and say what was done about it. Our page on roof damage from foam removal shows how that is judged.
A condition report on the roof structure
RICS cautions that poorly fitted insulation may cause dampness and condensation nobody planned for, and wants a qualified professional to do the calculations. It also says foam can sway a surveyor's opinion of value. A condition report answers both worries: it tells the reader whether the roof was affected while the foam was there.
Moisture readings on the timbers, a note of any decay and a view on whether the covering and underlay are sound all belong in that report. If the underlay was damaged or has aged badly, the report should say whether it needs replacing. We cover that decision on the page about a new membrane after spray foam.
Where a lender or buyer's surveyor wants a view from someone independent of the contractor, you may need a separate surveyor's report. That is one more reason to ask the lender what they accept before you commission anything.
Completion documents and what they can prove
People often ask for a removal certificate. No single form is recognised by every lender, so treat the term loosely. What counts is the detail behind the paper. A one-line statement that foam was removed carries little weight. A document naming the property, the dates, the method, the extent, the findings and the waste route, and backed by photographs, carries a good deal more.
Consider too what happens if the contractor has gone by the time you sell. Our page on a spray foam installer that has gone out of business explains why a record you hold yourself is more dependable than one you must request later.
Whichever route you take, keep the whole file in one place, in digital form, and hand over copies rather than originals. Back it up away from the house. A file that can be produced in a minute makes a conveyancing delay much less likely, and it spares you from rebuilding evidence that cannot be recreated once the roof is closed up again.
Evidence for lenders: two more questions
Will a lender definitely lend once the foam has been removed?
No lender can be promised in advance. What good evidence does is let the lender judge the property as it is now, rather than as it was. Ask your lender or broker directly, get their answer in writing, and remember that their policy may have changed since you last checked.
Do I need to keep the evidence if I am not selling for years?
Yes. Photographs, the written account and the condition report cost little to store and are very hard to recreate later. A buyer, surveyor or lender may ask long after the roof has been covered over and the contractor has moved on. Keep copies in two places.
