Spray foam insulation in your loft or roof can stop a sale, delay a remortgage, or block equity release. But to satisfy surveyors and lenders, simply removing the foam isn’t enough. You need to follow a clear, lender-compliant process — from selecting the right removal company to prepping for inspection and getting formal sign-off.
This step-by-step spray foam removal checklist ensures your home is mortgage-ready and your documentation is solid.
Step 1: Identify the Problem Early
Confirm spray foam insulation is present in your loft or roof space
You’ve been declined for a sale, mortgage, or equity release due to spray foam
Or you’re preparing for a property survey and want to get ahead of potential issues
Tip: Most UK lenders will not approve a property with any spray foam in the roof. Acting early prevents lost time, buyers, and money.

Step 3: Choose a Trusted Spray Foam Removal Company
Make sure your provider offers:
Specialist spray foam insulation removal (not just general loft clearance)
Manual-only removal (no ice blasting, solvents, or heat tools)
Full photographic documentation: before, during, and after
A spray foam removal certificate accepted by lenders
Advice on ventilation and timber condition
Clear timelines and transparent pricing
Avoid any contractor who:
Offers same-day removal
Won’t put the quote in writing
Doesn’t mention photographic evidence or certification
Step 4: Spray Foam Removal Day – What to Expect
Clear the loft of personal belongings
Ensure access to the loft is safe and unobstructed
The team will remove all visible and hidden spray foam
The loft will be left clean, with all waste professionally disposed of
The process takes 1 to 3 days depending on size and foam thickness
Step 5: What Documents Should You Receive?
Ask for a full documentation pack including:
Spray Foam Removal Certificate
Includes company details, address, removal method, and confirmation of full foam removal
Before, During & After Photos
Show foam coverage, manual removal in progress, and exposed rafters after
Structural Notes
Confirms timbers, battens, and joints are free of damp or damage
Moisture or Ventilation Report (if needed)
Especially important if the foam caused condensation or mould
Step 6: Prepare for the Surveyor’s Visit
Before the survey:
Ensure safe, clear access to the loft
Use a portable light if necessary
Remove anything obstructing the timbers or insulation view
Keep all documentation printed or stored as a single PDF to hand over
Surveyors will look for:
Fully exposed roof timbers and battens
No foam residue
No damp, staining, or mould
Properly completed, credible documentation
Step 7: Lender Review and Final Sign-Off
Once the surveyor completes their report and confirms the foam is gone and the roof is in good condition:
Your lender will review the documentation and photos
If all requirements are met, your sale, mortgage, or equity release can move forward
Spray Foam Removal Tips: Do It Right the First Time
Always use a manual-only removal specialist. This is what lenders prefer.
Don’t rely on a general builder or roofer — many removals fail because they lack experience with spray foam compliance.
Check if your contractor offers a removal certificate as standard — not all do.
Make sure all photos clearly show the same space (before, during, and after) — surveyors want to see continuity.
Avoid re-insulating immediately. Lenders need to inspect the roof in its bare state before any new insulation is applied.
Don’t delay paperwork. The longer it takes to get photos and a certificate, the longer your mortgage process is on hold.
Ask about ventilation. Once the foam is removed, confirm airflow is restored so you don’t end up with future condensation issues.
Common Mistakes to Avoid
Using unqualified contractors who don’t understand lender requirements
Accepting verbal confirmation or a receipt instead of formal documentation
Failing to prep the loft properly before the survey
Rushing to re-insulate before surveyor sign-off
Submitting incomplete photo evidence with no timestamps or consistency
