RICS Guidance on Spray Foam
What RICS-style survey concerns mean for homeowners with spray foam insulation in the loft.
Why surveyors flag spray foam
Surveyors are asked to comment on property condition and valuation risk. Spray foam can make that harder if it covers timbers, roof felt, fixings, or ventilation paths.
What the report wording means
A report may simply note that foam is present, or it may recommend further investigation, specialist advice, or lender review. The recommended next step depends on that wording.
How to prepare for follow-up
Keep the survey report, any installation paperwork, foam warranty, photographs, and lender comments together. These documents help shape the survey and quote conversation.
Common questions
Does a RICS survey always require removal?
No. A survey can trigger further investigation without automatically requiring removal. Lender policy may be the deciding factor.
Can removal improve survey confidence?
It can if it exposes the roof for inspection and produces clear completion evidence, but acceptance depends on the buyer, lender, and surveyor.
