Spray foam insulation was once marketed as an effective way to improve energy efficiency, but many homeowners are now discovering the hidden problems it can create. Across the UK, surveyors and mortgage lenders are increasingly flagging spray foam as a concern due to the potential damage it can cause to roof structures and ventilation systems.
One of the biggest issues with spray foam insulation is trapped moisture. When foam is applied directly to roof timbers and felt, it can prevent the roof from breathing properly, leading to condensation, damp, timber rot, and even structural weakening over time. In many cases, homeowners only become aware of the problem when trying to sell or remortgage their property and a survey identifies the foam as a risk.
