The hidden problems associated with spray foam insulation in roof spaces.
The two main types of spray foam suitable for roof voids are open-cell and closed-cell spray foam. Open-cell foam is soft and flexible, primarily used for insulation, while closed-cell foam is rigid and serves as both insulation and a vapor barrier.
Mortgage Lenders
UK mortgage lenders are hesitant to lend on properties with spray foam roof insulation due to concerns about potential moisture issues and the difficulty of properly inspecting the roof structure. This can make it difficult for homeowners to sell or remortgage their properties.
Inspection Challenges
Lenders’ surveyors may find it difficult to assess the condition of the roof timbers and overall roof structure when spray foam is present.
Uncertainty and Risk
The potential for long-term damage and the difficulty of assessing the situation can lead lenders to view the property as a higher risk.
Moisture and Ventilation
Spray foam can create a near-airtight seal, potentially trapping moisture and reducing ventilation in the roof space. This can lead to condensation, mould growth, and timber decay.
Address Concerns Early:
If considering a mortgage on a property with spray foam, be prepared to address any lender concerns and potentially remove the insulation.
