If your property has spray foam insulation applied within the roof space, it can sometimes make it difficult to assess the condition of the timbers and structure beneath it. In some cases, incorrectly installed spray foam insulation can trap moisture against timber, reduce ventilation within the roof void, or conceal underlying defects such as leaks or timber decay. A professional spray foam insulation survey is the most reliable way to understand whether the insulation is affecting the condition of your property and whether any further action may be required.
During a Timberwise spray foam insulation survey, an experienced specialist will carry out a detailed inspection of the roof space and the insulation itself. The surveyor will assess how the spray foam has been applied, identify whether it is open-cell or closed-cell insulation, and check whether it has been installed to appropriate standards. In some cases, a small section of the foam may be carefully removed so that the underlying timbers, roofing felt, or other materials can be inspected and moisture readings taken. This helps determine whether the insulation has caused or concealed problems such as timber decay, dampness, or insect activity.
Following the inspection, you will receive clear professional advice outlining the findings and any recommended next steps. The purpose of the survey is to establish whether the spray foam insulation is performing as intended or whether it may be contributing to issues such as moisture retention, condensation within the roof void, or hidden structural defects. By identifying these issues early, appropriate remedial measures can be recommended to protect the condition of the roof structure and surrounding timbers.
