Top 5 Questions We Get About Spray Foam Removal – Answered Honestly
If your home has spray foam insulation in the roof, you’re likely already facing the consequences — mortgage lenders refusing applications, buyers pulling out, or surveyors raising red flags.
At National Spray Foam Advice, we hear from homeowners daily. So here are the top 5 questions we get about spray foam removal, answered with honesty and clarity.
1. Do I Really Need to Remove My Spray Foam Insulation?
Yes — if you want to sell, remortgage, or protect your property.
Spray foam insulation is now flagged by almost all UK lenders and surveyors as a serious issue. Even if your roof looks fine from the outside, the foam can hide condensation, damp, or timber decay — and simply removing a section or ignoring it isn’t enough.
✅ Full removal is essential to restore your home’s value and mortgageability.
2. Can I Get a Mortgage After the Spray Foam Is Removed?
Yes — but only with proper documentation.
Once spray foam is fully and professionally removed, and your roof is assessed to be structurally sound, lenders may reconsider your mortgage application. But this hinges on having an official Spray Foam Removal Certificate.
🔒 This certificate is your proof that:
The foam was removed safely and completely
The roof was inspected post-removal
The job met industry standards
Most of our trusted partners include this certificate as part of the removal package — and it’s vital for solicitors, lenders, and buyers.
3. How Much Does Spray Foam Removal Cost?
Typical costs range between:
£2,500 – £4,500 for standard lofts
£5,000+ for larger or complex removals
Re-insulation, timber repair, and certification may be added depending on your situation
We only recommend experienced professionals who are transparent, fairly priced, and include certification as standard.
4. How Long Does It Take to Remove Spray Foam?
Most jobs take 1 to 3 days.
Factors that affect timing:
Size of the loft or roof
Thickness and type of foam
Timber condition and ventilation status
Professional teams will give you a full breakdown of timelines and steps, including when your certificate will be issued.
5. Can I Just Leave the Spray Foam in Place If I’m Not Selling Yet?
We strongly advise against it.
Leaving spray foam in your roof can:
Hide developing issues like rot or damp
Reduce your home’s resale value
Make future sales or remortgaging impossible
Lead to voided warranties or insurance issues
Even if you’re not moving now, getting ahead of the problem protects your home’s future.
📄 Why Certification Matters More Than Ever
Spray foam removal isn’t just about ripping out insulation — it’s about restoring your home’s value and providing evidence that the job was done right.
💼 Without a Spray Foam Removal Certificate, lenders may still reject your property, even after removal.
That’s why we only recommend partners who include certification — no cutting corners.
