Spray foam

01 The problem
A roof you can't sell, mortgage, or insure.
Trapped moisture, rotting timbers
Foam forms an impenetrable barrier on rafters. Water that would normally evaporate is held against the wood, leading to decay and structural weakness over months and years often hidden until it's serious.
Surveyors can't see what's underneath
A standard valuation requires visual inspection of roof timbers. Foam makes that impossible, so the surveyor flags the property as a risk lenders default to refuse.
Off-gassing and indoor air quality
Improperly mixed or ageing foam can release isocyanates and VOCs into the loft and the living space below, a concern raised in multiple UK government and industry reviews since 2022.
Insurance and warranty exclusions
A growing list of household insurers now exclude damage linked to spray foam, leaving owners exposed to repair costs they would normally be covered for.
What the UK’s official surveying body says
The Royal Institution of Chartered Surveyors (RICS) recognises in its consumer guidance that spray foam insulation can affect mortgage valuations and surveys because it conceals the roof structure, preventing the visual inspection a surveyor is required to carry out. RICS also notes that where foam is poorly installed or seals in moisture, a leak behind it can go undetected and lead to timber decay. Read the official RICS guidance →
02 2026 lender policies
Who's saying no to spray foam.
Every major UK mortgage lender has tightened its position over the last 24 months. We track each policy weekly. The table below reflects the current public stance of the UK's largest lenders.
Smaller building societies and specialist lenders are following the same trajectory. A lender-recognised completion certificate from Countrywide reverses the position in 96% of cases we've handled.
03 Open-cell vs closed-cell
Open-cell or Closed-cell ?
Two products. Two completely different removal jobs. We handle both, but the cost, time, and structural impact depend entirely on which one's been sprayed onto your timbers.
Softer, Breathable, Recoverable.
Open-cell foam is lower density and remains slightly flexible. Our teams cut, peel, and brush it away from timbers, then inspect each rafter, replace any compromised felt, and re-insulate to current standards.
Sample · Open-cellDense, Bonded, Aggressive.
Closed-cell foam adheres so tightly to roof timbers that removing it intact is rarely possible. Most closed-cell projects involve replacing rafters, stripping the roof externally, and laying new membrane and tiles before re-insulating.

The transformation
speaks for itself.
Spray foam removed cleanly and completely — rafters left dry, clear, and mortgage-ready.

Real results.

"I had a great experience dealing with Countrywide Roofing & Insulation. They explained everything clearly — from the survey right through to the completion certificate. The team were first class, and they even brought the date forward so I could proceed with the estate sale."
"Ours was a difficult and awkward job but the experienced Countrywide teams always had it under control. Staff were courteous and respectful throughout and the inevitable small problems were dealt with speedily."
"Great company. Punctual, efficient, and straightforward to deal with. The spray foam removal team removed the foam manually with scrapers on the rafters. They were courteous, took my feedback into consideration, and left everything spotless."
"Excellent communication. The quote was spot on and the lads worked later until the job was done. Arrived each morning at the agreed time, cleared up after themselves, and were very polite. Highly recommend."

Frequently asked questions
Why do mortgage lenders reject properties with spray foam insulation?
Lenders reject spray foam properties because spray foam traps moisture, damages roof timbers, and creates uncertainty around structural integrity. Professional removal with a lender-recognised certificate is typically required before a mortgage can be approved.
Can I remove spray foam insulation myself?
DIY removal is not recommended. Spray foam is highly adhesive and improper removal will damage your roof and leave residues. Lenders also require a professional completion certificate.
How long does spray foam removal take?
Open-cell removal typically takes 2–5 days. Closed-cell removal takes 7–14 days because timbers often need replacing.
How much does spray foam removal cost?
Open-cell removal typically ranges £3,000 to £10,000. Closed-cell removal ranges £10,000 to £50,000 because of additional timber replacement and roofing works.
Will spray foam removal make my home mortgageable again?
Yes. Once removed and a completion report issued, most UK lenders will consider the property mortgageable again.
What is the difference between open-cell and closed-cell removal?
Open-cell foam is softer and easier to remove. Closed-cell foam is denser and harder, often requiring timber replacement, making it more complex and costly.
