At Countrywide Roofing and Insulation, we've seen firsthand how improperly installed spray foam can cause homeowners headaches. This blog will explore why some lenders are reluctant to approve homes with spray foam insulation, the risks involved, and how we can help resolve these issues, we are always on phone to answer any question you have in the blog on 0808 134 2352
The Growing Concern: Spray Foam and Mortgages
Recent findings suggest that a quarter of the UK's largest mortgage providers refuse to lend against properties with spray foam insulation in the roof space. This issue has left many homeowners struggling to sell their homes or secure new mortgage terms.
The concerns arise from the potential risks associated with spray foam insulation, including:
- Poor Ventilation: Improperly installed foam can trap moisture, leading to rot and decay in roof timbers.
- Inspection Barriers: Spray foam often covers structural elements, making it difficult for surveyors to assess the roof's condition.
- Documentation Gaps: Many installations lack proper certification or warranties, raising red flags for lenders.
A Case in Point: The Rowe Family's Experience
Wendy Rowe's story highlights the challenges faced by homeowners with spray foam insulation. Her late father had spray foam installed under the government's Green Homes Grant scheme, believing it would improve his home's energy efficiency. However, prospective buyers were deterred by the foam in the roof when it came time to sell the house.
After failed sales attempts and lender objections, Wendy had to replace the entire roof. This, along with administrative and surveyor fees, cost the family thousands of pounds. Her experience underscores the importance of understanding the implications of spray foam before installation—and the value of professional removal services when problems arise.
What Is Spray Foam Insulation?
There are two primary types of spray foam insulation, each with distinct properties and best-use scenarios:
Closed Cell Spray Foam
Closed-cell spray foam is a dense, rigid form of insulation known for its high thermal resistance and moisture barrier qualities. It can significantly strengthen roof structures and provide exceptional insulation performance. However, this type of foam also expands with considerable force and can put pressure on roof timbers if not carefully applied. More importantly, its impermeable nature means it can trap moisture, leading to condensation problems, timber decay, and reduced airflow—especially if ventilation is inadequate. These issues often arise when closed-cell foam is used in older homes or installed by unqualified contractors.
Open Cell Spray Foam
Open-cell spray foam is lighter and more flexible than its closed-cell counterpart. It allows for some air and moisture permeability, which makes it better suited for domestic roof spaces where breathability is essential. When installed correctly, open-cell foam can provide an effective insulation solution without compromising the integrity of the roof structure. However, it's unsuitable for every situation—especially where proper vapour control layers or ventilation are lacking. Even open-cell foam can contribute to moisture retention and mould growth in such cases.
Why Are Lenders Hesitant?
For mortgage providers, the key concerns are the hidden risks that spray foam can pose to a property. Poor installation can lead to structural damage, such as:
- Rotting Roof Timbers: Trapped moisture caused by restricted airflow can weaken wooden roof structures.
- Increased Repair Costs: Surveyors often recommend costly remedial work before approving mortgages.
- Inspection Challenges: Spray foam can hide underlying damage, making it difficult for valuers to provide accurate property assessments.
In response to these risks, some lenders outright refuse to approve mortgages for homes with spray foam insulation, while others impose strict conditions such as requiring a specialist inspection or documentation proving proper installation.
How Can Homeowners Address These Issues?
If you're dealing with spray foam insulation in your home, there are steps you can take to resolve lender concerns and protect your property:
- Review Documentation: Ensure you have all relevant certificates, warranties, and survey reports.
- Seek Professional Assessments: Have your roof inspected by a qualified surveyor familiar with spray foam insulation.
- Consider Removal: If issues are identified, removing the spray foam may be the best solution.
